The cross section of the first engaging groove 130 is an inverted trapezoid, and the length of the bottom of the trapezoid is equal to the length of the two sides, and the included angle is 120 degrees. The second card slot 230 is identical in structure to the first card slot 130. In the closed state, the first engaging groove 130 and the second engaging groove 230 can enclose to form a regular hexagonal prism-shaped hole structure 300, and the axial direction of the hole structure 300 is along the length direction of the forceps handle. The hexagonal prism-shaped hole pattern 300 is capable of mating with the shank of a screwdriver bit, extending outwardly from the distal end of the bit when the screwdriver bit is inserted into the hole pattern 300.
The pliers (10) have two parallel planes perpendicular to the hinge axis of the first and second clamping members (100, 200), and the locking device (400) is disposed on one of the planes (600) at the junction of the hinge of the first and second clamping members (100, 200) and the handles of the pliers.
Specifically, the locking device 400 includes a lever 410 and a locking slot 430.

Compared with the structure in which the hole structure 300 is provided at the bit 110, the hole structure 300 of the present embodiment is closer to the hinge axis of the first clamping member 100 and the second clamping member 200, so that the moment to the hinge axis formed by the reaction force of the screwdriver bit to the bit shank 120 is smaller, and thus the load borne by the locking device 400 is smaller.
In some alternative embodiments, the cross section of the first slot 130 is rectangular, and the length of the bottom side is twice as long as that of the two sides. The second card slot 230 is identical in structure to the first card slot 130. In the closed state, the first and second engaging grooves 130 and 230 can enclose a hole structure 300 in the shape of a regular quadrangular prism.
In other alternative embodiments, the aperture structure 300 formed by the first card slot 130 and the second card slot 230 has a regular triangular prism shape.
In alternative embodiments, the locking mechanism 400 may also be located on the jaws, such as by providing a threaded hole in one jaw and a through hole in the other jaw, and tightening the screw to hold the jaws together. In alternative embodiments, the locking device 400 may also be provided on the handles, such as a collar provided at the end of the handles, or a catch provided between the handles. So long as the structure can prevent the clamp head or the clamp handle from opening and does not influence the holding of an operator.
In some alternative embodiments, the locking groove 430 of the second clamping member 200 is arc-shaped and concentric with the axis 420 of the first end 411 of the driving lever 410, the cross section of the locking groove 430 is rectangular, and the depth direction of the locking groove 430 is parallel to the axial direction of the axis 420. Correspondingly, the distance between the boss 413 on the lever 410 and the axis 420 of the first end 411 of the lever 410 is equal to the radius of the arc-shaped locking groove 430. The boss 413 of the second end 412 can enter the locking groove 430 or be released from the locking groove 430 when the lever 410 is rotated. The toggle 410 prevents the binding clip/handle from opening when the boss 413 is in the locking slot 430.
