Abstract:
A nailer includes a base seat and at least one abutment member. The base seat has at least one engaging structure. The abutment member has at least two engaging portions that are spaced apart from each other, and a connecting portion that is connected between the engaging portions. The engaging structure engages detachably one of the engaging portions. Each of the engaging portions has an engaging surface that is connected to the connecting portion and that abuts against the engaging structure. The other one of the engaging portions further has an abutment surface that is opposite to the engaging surface thereof, and that is for abutting against the object.
Abstract:
A firing-operation totalizing device for a gas nail gun includes two pressure areas, a pressure feedback unit mounted in a body, and an electric control unit. The pressure areas are constituted by an interior of a combustion chamber and an interior of a cylinder body. The pressure feedback unit outputs a pressure signal in response to each pressure change of at least one of the pressure areas. The electric control unit includes a control circuit that totalizes the number of the firing operations based on the pressure signals received thereby. As such, the totalized number of the firing operations is increased only when a pressure change of the at least one of the pressure areas occurs due to an explosion to totalize accurately the number of effective firing operations.
Abstract:
A nail magazine for a power nail-driving tool includes an elongated magazine unit and a leaf spring unit which includes an elongated body and first and second guiding members. The elongated body has a rearward end fixed to the elongated magazine, and a forward end which is movable between a blocking position and a yielded position. The first guiding member has a barrier shoulder configured to block loading movement of a nail strip when the nail strip is loaded in a wrong orientation. The second guiding member has a ramp-up region configured to permit the nail strip to depress the forward end to the yielded position when the nail strip is loaded in a correct orientation.
Abstract:
A bar connecting apparatus is used for firing a string of clips one at a time to connect two intersecting bars together. The bar connecting apparatus includes: a main body having a front end portion formed with an ejection opening; a driving unit including a hammer disposed in the main body, and a drive disposed in the main body for reciprocating the hammer; and a magazine unit including a magazine connected to the main body and adapted for storing the clips, and a clip pushing device for pushing one of the clips into the ejection opening so that a portion of the one of the clips extends outwardly from the main body through the ejection opening.
Abstract:
A pneumatic pallet nailer includes a nailer body, a trigger member, a pallet clamp controlling member, a pallet clamp cylinder and a pallet clamp. The trigger member is disposed on the nailer body. The pallet clamp controlling member is disposed on the nailer body and includes an internal space, a first pipe, a second pipe, a third pipe and an actuating valve. The air in the nailer body is communicated with the internal space by the first pipe and the second pipe. The third pipe is communicated with the internal space. The actuating valve is movably disposed in the internal space, and the actuating valve is actuated and positioned at a first position or a second position. The pallet clamp cylinder is communicated to the third pipe. When the trigger member is pressed, the pallet clamp is actuated by the pallet clamp cylinder to clamp a workpiece.
Abstract:
A nail gun includes a gun body, a safety unit and an adjusting unit. The safety unit includes a first safety member movable relative to the gun body, and a second safety member for being pushed by the first safety member. The adjusting unit includes a switch member movable between a deep-drive position and a shallow-drive position. The switch member has a first abutment surface aligned with the first safety member when the switch member is at the deep-drive position, and a second abutment surface aligned with the first safety member when the switch member is at the shallow-drive position.
Abstract:
A nail gun includes a body, a valve unit, a nail striking member and a detector. The body has a nail path, an air chamber, and an intake chamber guiding flow of air into the air chamber. The nail striking member is drivable by air pressure in the air chamber for striking a nail in the nail path. The valve unit is operable to switch between unblocking and blocking states to respectively permit and prevent fluid communication between the intake chamber and the air chamber. The detector is connected pivotally to the body, and is contactable with the valve unit such that, when there is no nail in the nail path, the valve unit is controlled by the detector to be in the blocking state.
Abstract:
An electric power tool includes a motor, a lifter, a firing pin, an electromagnet, a driving circuit, a latch, and a controller. The lifter is driven by the motor to drive the firing pin to perform a firing action. The driving circuit provides electric current to excite the electromagnet. The latch is moved by the electromagnet from a blocking position where the latch blocks the firing pin to move in a firing direction to a non-blocking position where the latch does not block the firing pin when the electromagnet is in an excited state. The controller, during an excitement period, controls the driving circuit to provide constant current for a first time period to excite the electromagnet to the excited state, and provide pulsating current for a second time period to keep the electromagnet in the excited state.
Abstract:
A pneumatic electric nail gun includes a muzzle unit, a striking cylinder that is connected to the muzzle unit, a piston rod subunit that extends movably from the striking cylinder into the muzzle unit, an electric unit that drives movement of the piston rod subunit from a standby position to a nail-striking position for striking a nail, and a connecting unit that includes a plurality of fasteners and a plurality of buffer members. The fasteners extend through the electric unit and secure the electric unit to the muzzle unit. Each of the buffer members surrounds a respective one of the fasteners and fills a space between the respective one of the fasteners, the electric unit and the muzzle unit for shock absorption during a nail-striking process.
Abstract:
An electric nail gun includes a nail-striking subunit that is adapted to strike a nail, a lifting wheel that is movable to become engageable and not engageable with the nail-striking subunit, a driving member that is rotatable by a motor, and a transmission shaft that is movably connected between the driving member and the lifting wheel, and that is convertible between a first position, where the lifting wheel is engageable with the nail-striking subunit such that rotation of the driving member results in movement of the nail-striking subunit, and a second position, where the lifting wheel is not engageable with the nail-striking subunit such that rotation of the driving member does not result in movement of the nail-striking subunit.
