摘要： A snap hook includes a body, a gate, a connection link, and a coupling. The body has a central portion positioned between an upper portion and a lower portion. The gate is pivotally coupled proximate the central portion. The gate and the body selectively form a closed configuration that defines a hook connection passage and an open configuration that provides access to the hook connection passage. The connection link has an upper end pivotally coupled proximate the central portion of the body and a lower end including a body connection aperture. The coupling interconnects the lower end and the lower portion. The coupling is configured to break when a select amount of force is applied to the lower end and release the lower end from the lower portion to redirect the select amount of force from the lower portion to the central portion of the body.

摘要： An enhanced safety hook includes a hook body, a latch member, an operation handle and a spring member. The hook body includes a hook hole having a hook opening, a hook end formed at a top end thereof, a pin slot at a position below the hook opening, and a guide slot. The latch member includes a main plate and two side plates define an upside-down U-shape frame, a peripheral edge bridged between the two side plates in such a manner that a top end of the latch member constructs a mouth for receiving the hook end, a guide arm connected to the two side frames to couple with the guide slot, and a pin element coupling with the pin slot. The pin element is movably provided in the pin slot in such a manner that the mouth of the latch member is capable of detaching from the hook end, so that the latch member unlocks the hook opening by means of rotation of the pin element in the pin slot, while the guide arm slides in the guide slot for preventing the latch member from having contact with the inner wall of the hook body along the hook hole. The operation handle has a rotation hole for the pin element to pass through so as to enable the pin element to move in the pin slot. The spring member retains the latch member in a position that the latch member tends to lock the hook hole.

摘要： A precision safety ring-shaped hook provides a timing gauge structure which is composed of a sliding groove, a pair of rail members, and a block pin. Each of the rail members has an arc surface. When a first locking axle is moved to an open slot, a first end of a hook body is moved away from the first guiding member and, at the same time, a block pin moves to the arc surface area, so that when the first locking axle is swung in a hook cavity of the hook body, a driving pin is able to position at the arc surface and thus a locking member can be guided by the arc surface to open the opening of the hook body. Accordingly, the opening or shutting of the opening of the hook body by the locking member can thus be precisely operated at one time to provide an advance precision value for the hook and eliminate the interference and impacting drawbacks.

摘要： A carabiner includes a fixed C-shaped body equipped with a securing part, and a gate movable around a pivoting axis between a closed position and an open position. The gate includes a latching part and a locking ring fitted coaxially around the gate. An end head of the gate partially surrounds the securing part in the closed position, and includes a shoulder acting as end-of-travel stop for the ring in the locked position.

摘要： A safety hook includes: a hook body having a base segment that has front and rear end portions, the rear end portion being formed with an elongate groove that is defined by a groove-defining wall which has a lower surface; a latch locking unit including a limiting rod that extends through the elongate groove and that is in sliding contact with the lower surface of the groove-defining wall; and a latch unit pivoted to the front end portion. The latch unit has a limiting arm unit extending toward the limiting rod, disposed above the limiting rod, and arrested by the limiting rod when moving downwardly.

摘要： A karabiner comprises a generally C-shaped body, with its free ends curved towards each other and forming a gap therebetween, and a gate for closing the gap, the gate being formed of a wire member shaped and located on one free end of the body, such that it is constrained to close the gap and the other end of the gate having a slot for receiving a shaped end of the gate.
