The first tube body 21 is installed on the cross bar 12. The second tube body 22 is used to be sleeved on the steel bar 3, so as to limit the support frame 1.

[0026] Furthermore, the first tube body 21 is slidably sleeved with the cross bar 12, a first stop screw 23 is screwed on the first tube body 21, and a second stop screw 24 is screwed on the second tube body 22. In this way, the position of the support frame 1 can be moved left and right, and the height of the sleeve 2 can be positioned and adjusted by the second stop screw 24 on the second tube body 22. When in use, refer to Figure 2 , by moving the adjusting sleeve 2 up and down, the second tube body 22 slides up and down along the steel bar 3, and after adjusting to a suitable position, the second limiting screw 24 is tightened, and the second limiting screw 24 abuts against the steel bar 3, thereby limiting the adjusting sleeve 2 and the steel bar 3. Similarly, when the left and right positions of the support frame 1 are adjusted, the first limiting screw 23 is tightened to limit the support frame 1 and the first tube body 21.

[0027] In one embodiment, the pressing device 4 includes a pressing member 42, which is installed on the top of the longitudinal rod 11 by bolts. In this embodiment, the pressing member 42 is a plate body, a threaded hole is set on the top of the longitudinal rod 11, and the pressing member 42 is installed on the top of the longitudinal rod 11 by bolts.

[0028] In another embodiment, see Figure 2 The pressing device 4 includes an insert rod 41 and a pressing piece 42. The pressing piece 42 is fixedly connected to the top of the insert rod 41.
