The slide grooves 31 penetrate into the interior of the support frame 3. An adjusting mechanism is provided on the support frame 3, and the adjusting mechanism includes a connecting block 32 and a slider 51. The connecting block 32 is provided on the support frame 3, and the slider 51 is provided on the clamping plate 5. The connecting block 32 is provided at the upper and lower ends of the slide groove 31, and a threaded hole 321 is provided on the connecting block 32. The clamping plate 5 is symmetrically and slidably provided on the inner wall of the support frame 3, and the slider 51 is slidably provided in the slide groove 31. The slider 51 extends from the slide groove 31 to the outside of the support frame 3, and the slider 51 and the connecting block 32 are docked. A rotating hole 52 is provided on the slider 51, and the threaded hole 321 is aligned with the rotating hole 52. A bolt 54 is provided in the threaded hole 321, and the bottom end of the bolt 54 is rotatably provided in the rotating hole 52. The distance between the two clamping plates 5 can be adjusted by rotating the bolt 54.

[0032] like Figure 1 , 3 As shown in , 4, 5, and 6, a notch 53 is provided at one end of the clamping plate 5, and the notch 53 is provided at a symmetrical position of the two clamping plates 5.
