[0030] like Figure 2 As shown, in one embodiment, a mounting hole 19 is provided on the inner side of the fixing block 2, and the fixing block 2 can be connected to a ground support or the like by bolts, so that the fixing block 2 can be fixed to the ground for use, thereby improving adaptability.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, a handle 20 is fixed to one end of the two telescopic rods 9, and both handles 20 are made of rubber material for easy hand-held rotation.

[0032] Embodiment 2:

[0033] like Figure 4 As shown, in the second embodiment, the adjustment mechanism includes two mounting grooves 10 symmetrically arranged on the inner side of the rotating plate 5, and two sliders 11 symmetrically fixed to the lower side of the U-shaped plate 6, wherein a threaded rod 12 is rotatably connected to the inner side of one of the mounting grooves 10, and a rotating disk 13 is fixed to one end of the outer side of the threaded rod 12, and one of the sliders 11 is rotatably connected to the outer side of the threaded rod 12 through a thread;

The slide plate 16 is slid along the outer side of the slide rod 15 to release the limit between the limit rod 161 and one of the limit holes 18. The turntable 13 is held and rotated. The rotation of the turntable 13 drives the threaded rod 12 fixed thereto to rotate synchronously. The rotation of the threaded rod 12 drives the U-shaped plate 6 to move through the threaded engagement, and then the two limit blocks 7 move accordingly. Move to adjust the spacing. After the adjustment is completed, the elastic potential energy of the spring 17 is used to make the limit rod 161 again plugged into the corresponding limit hole 18 for limiting.
