bolt portion includes the bolt, the bottom integrated into one piece of bolt has the wedge head, the both sides of bolt have all been seted up with two sets of bolt grooves, bolt groove and the mutual adaptation of the boss that corresponds the position, screens under bolt first state and the second state can be realized to upper and lower two sets of bolt grooves, is the first state during the initial position, is the second state when forcing the jack catch upset, can keep cross state under the initial state, under upset state, the lower extreme upset of jack catch to both sides and compress tightly on panel for the buckle possesses fixed function.

Preferably, the diameter of the wedge-shaped head is smaller than that of the plug pin, and the bottom of the wedge-shaped head is designed to be a convex head, so that the wedge-shaped head can be more conveniently propped against the crossed part of the clamping jaw and force the clamping jaw to overturn.

Preferably, the clamping jaws are 7-like in shape, one end of each clamping jaw is vertically arranged below the root of each clamping jaw, the other ends of the two groups of clamping jaws are in a cross shape and are arranged right below the wedge-shaped heads, the cross state can be kept in an initial state, and the lower ends of the clamping jaws are turned over to two sides and are tightly pressed on plates in an overturning state, so that the buckle has a fixing function.

Preferably, the claw root is made of deformable materials and can be in a plastic state, and the wedge-shaped head can force the claw to overturn through the deformable materials at the claw root, so that the fixing function can be achieved.

Preferably, the length of bolt with the degree of depth that leads to the groove equals, and the top of bolt is the fillet setting for when pushing up on panel, the top of bolt finally keeps the parallel and level state with the top of buckle base.

Preferably, the quantity of bolt recess is four, and two bolt recess settings are in the left side of bolt inner wall, and two remaining bolt recess settings are on the right side of bolt inner wall, and use the perpendicular bisector for the bolt to set up as symmetry axis symmetry between the bolt recess of both sides, and screens under bolt first state and the second state can be realized to upper and lower two sets of bolt recesses, is the first state during initial position, is the second state when forcing the jack catch upset, can realize fixing more firm effect.

The working principle is as follows: as shown in figure 1 in the initial state, the jaw can keep the cross state in the initial state, the bolt is pressed into the buckle base, the lower end of the jaw is turned over to two sides and is pressed on the plate, and as shown in figure 2, the buckle has a fixing function, so that the buckle has the advantages of small assembling force, large disassembling force and firmer fixation.

Compared with the prior art, the invention has the following advantages:

according to the invention, the wedge-shaped head is in the first state at the initial position and is in the second state when the clamping jaw is forced to turn over, the crossing state can be kept at the initial state, and the lower end of the clamping jaw is turned over to two sides and is tightly pressed on a plate in the turning state, so that the buckle has a fixing function, and has the advantages of small assembling force, large disassembling force and firmer fixing.
