Abstract: A power tool has a body, a trigger, a motor, a shaft set, a ball screw, and a pre-fastening module. The pre-fastening module has a first pre-fastening detecting member and a second pre-fastening detecting member. The first pre-fastening detecting member is moved with a connecting shaft of the shaft set in an axial direction. The second pre-fastening detecting member is located on a moving path of the ball screw. When a threaded spindle of the shaft set is inserted in a rivet nut and the connecting shaft is pressed to move inward the body, the first pre-fastening detecting member is moved to align with the second pre-fastening detecting member, and the motor is started automatically to drive the threaded spindle to rotate relative to the rivet nut. The motor will be stopped automatically after the rivet nut is pre-fastened on the threaded spindle, and this is convenient in use.

Abstract: A fastening tool includes a housing, a handle, an anvil, a pin-gripping part, a motor, and a driving mechanism. The driving mechanism is configured to move the pin-gripping part along a first axis defining a front-rear direction, relative to the anvil. The driving mechanism includes a rotary member, a movable member, a driving gear and an idler gear. The rotary member has a driven gear formed on its outer periphery and is rotatable around the first axis. The movable member is connected to the pin-gripping part and configured to be linearly moved in the front-rear direction by rotation of the rotary member. The driving gear is configured to be rotated around a second axis extending in parallel to the first axis below the first axis. The idler gear is engaged with the driving gear and the driven gear.

Abstract: A power tool for joining a deformable element having a threaded shaft to a workpiece. The joining tool comprising a threaded dowel adapted to receive the threaded shaft and rotatably within the housing. A nose is arranged around the threaded dowel, and the dowel is slidably movable relative to the nose. A motor drives a drive train to rotate the threaded dowel. A hydraulic system drives another drive train to move the threaded shaft and compress the deformable element. The joining tool includes a sliding unit. The nose is attachable to the sliding unit, and in an attached position the nose is slidably connected to the housing so that the hydraulic system may move the nose axially to compress the deformable element.

Abstract: A mandrel collector includes a case body and an end plate. The case body has a connecting end for being connected to a rivet gun. The end plate is engaged with the case body and is opposite to the connecting end. The end plate has at least one receiving hole, wherein a hole section of the receiving hole is a hexagonal hole with six walls. The walls include three first walls and three second walls. Each of the first walls is connected between adjacent two of the second walls. The hole section is defined to have a central axis and a reference plane perpendicular to the central axis. On the reference plane, a side length of at least one of the first walls is smaller than side lengths of the second walls. With such design, the receiving hole could receive a head of an adapter and could rotate the adapter as a screwdriver.

Abstract: A fastening tool includes a motor, a fastening mechanism, a tool body and a main handle. The motor includes a motor body and a motor shaft. The fastening mechanism is configured to fasten workpieces via a fastener by pulling a pin of the fastener rearward relative to a tubular part of the fastener along a driving axis defining a front-rear direction of the fastening tool. The tool body houses the motor and the fastening mechanism. The main handle extends in a direction crossing the driving axis and connected to the tool body such that the main handle and the tool body together form an annular part. A rotational axis of the motor shaft extends parallel to the driving axis. A portion of the main handle is located in a rear space extending behind the motor body.

Abstract: A fastening tool includes a bolt-gripping part, an anvil, a motor, and a control part. When the bolt-gripping part grips an end region of a shaft part and moves relative to the anvil in a first direction of a longitudinal-axis direction, the anvil presses a collar fitted onto the shaft part in a second direction opposite to the first direction of the longitudinal-axis direction and inward in a radial direction of the collar, so that a hollow part of the collar is crimped to a groove while the workpiece is clamped between the collar and a head part, whereby swaging of a fastener is completed while the end region remains integrated with the shaft part. The control part completes swaging of the fastener by terminating a movement of the bolt-gripping part in the first direction relative to the anvil based on driving current of the motor.

Abstract: An impacting apparatus includes a spring anvil assembly and a drive mechanism that alternatively engages a the spring anvil assembly to actuate the spring anvil assembly to store potential energy in the spring anvil assembly, and which drive mechanism alternatively disengages the spring anvil assembly to allow the spring anvil assembly to launch and accelerate toward an impact target to deliver impact energy from the spring anvil assembly to the impact target. In an embodiment, the spring anvil assembly is biased to a start position by one of the impact target and the weight of the apparatus. The spring anvil assembly may comprise a gas spring or a spring, for example. The apparatus is capable of delivering multiple impacts to an impact target.
