The rear end of the moving rod 84 is fixedly connected with the pressing block 85. The recess at the upper end of the clamping block 81 is fixedly connected with the supporting spring 86. The supporting spring 86 supports and limits the moving block 87. When the pressing groove 89 is no longer subjected to extrusion, the supporting spring 86 is reset, driving the movable block 88 to move upwards and moving the limiting block 810 upwards, so that the limiting block 810 leaves the gap of the clamping block 812, thereby releasing the effect on the clamping block 81, so that the clamping block 81 is not affected during movement. The upper end of the supporting spring 86 is fixedly connected with the moving block 87. The two ends of the moving block 87 are fixedly connected with the movable block 88. The rear side of the movable block 88 is provided with the pressing groove 89.
