[0027] In one embodiment, a slide groove 22 is provided on the fork plate 11, and grooves 32 are provided on the two side walls of the slide groove 22. The fork plate 2 is slidably installed in the slide groove 22, and protruding protrusions 31 are provided at both ends of the fork plate 2 12. The protrusions 31 can be slidably inserted into the grooves 32, and the grooves 32 limit the up and down movement of the protrusions 31.
[0028] A rectangular hole 24 is provided on the bottom wall of the slide groove 22, which passes through the fork plate 11. In this embodiment, the rectangular hole 24 is rectangular, and a rectangular hole 25 is provided on the bottom of the fork plate 12. The shape and outline of the rectangular hole 25 are the same as those of the rectangular hole 24, so that the rectangular hole 24 and the rectangular hole 125 can be aligned up and down. After alignment, the limit block 27 can be inserted, and then the screw 28 can be inserted. After the screw 28 passes through the limit block 27, the other end is inserted into the top wall of the rectangular hole 25 and threadedly tightened, so that the upper half of the limit block 27 is located in the rectangular hole 25, and the lower half is located in the rectangular hole 24, so as to achieve the purpose of locking the fork plate 11 and the fork plate 2, so that the fork plate 12 can no longer slide in the fork plate 11.
