The outer walls of the opposite ends of the two clamping blocks 11 are fixedly connected with a rubber anti-slip pad 12, an adjustment mechanism 5 is arranged in the U-shaped seat 2, and a rotating mechanism 6 is arranged at the bottom of the base 1.

[0022] Further as Figure 1 and Figure 2 As shown, it is worth specifically explaining that the adjustment mechanism 5 includes a first movable groove 51 and a first motor 52. The first movable groove 51 is opened on the inner wall of the bottom surface of the U-shaped seat 2. The first motor 52 is fixedly connected to the bottom of the outer wall of one side of the U-shaped seat 2. The output end of the first motor 52 is coaxially fixedly connected with a rotating rod 53. The end of the rotating rod 53 away from the first motor 52 rotates through the outer wall of one side of the U-shaped seat 2 and extends to the inside of the first movable groove 51. The end of the rotating rod 53 away from the first motor 52 is coaxially fixedly connected with a driving gear 54, and the driving gear 54 is meshingly connected with a driven gear 55.

[0023] Further as Figure 1 and Figure 3 As shown, it is worth explaining in detail that the rotating mechanism 6 includes a mounting seat 61, a second movable groove 62 is opened on the top surface of the mounting seat 61, and the bottom surface of the second movable groove 62 is rotatably connected to a rotating shaft 63 arranged in a vertical direction, and a worm wheel 64 is fastened and sleeved on the outer surface of the rotating shaft 63, and the worm wheel 64 is meshingly connected to a worm 65, one end of the worm 65 is rotatably connected to an end wall inside the second movable groove 62, and the other end of the worm 65 rotates through the outer wall of one end of the mounting seat 61 and is coaxially fixedly connected to a hand wheel 66.
