[0029] The locking mechanism includes a pressure strip 7, a mounting groove 301 is provided at the front end of the lifting plate 3, and one end of a spring 8 is connected to the bottom wall of the mounting groove 301, and the other end of the spring 8 is connected to the bottom of the pressure strip 7 in the mounting groove 301, and a positioning rod 701 is also installed at the bottom of the pressure strip 7, and a positioning hole 607 matching the positioning rod 701 is provided on the rear arm body 6.

[0030] See also Figure 1 , further, the lifting mechanism includes a threaded adjustment rod 4, a lifting slot 2 is opened at the front end of the mounting frame plate 1, the lifting plate 3 is installed in the lifting slot 2, and a threaded adjustment rod 4 is rotatably installed in the lifting slot 2, and the threaded adjustment rod 4 is threadedly connected to the lifting plate 3;

[0031] Specifically, a threaded hole is provided on the lifting plate 3 , and the threaded adjustment rod 4 is threadedly connected to the threaded hole on the lifting plate 3 , thereby facilitating the lifting and lowering of the lifting plate 3 .

[0032] See also Figure 1 and Figure 2 Furthermore, mounting blocks are provided on both sides of the mounting frame plate 1, and the mounting blocks are connected to the wall by bolts, and the top of the threaded adjustment rod 4 passes through the top of the mounting frame plate 1 and is connected to the turntable.

[0033] See also Figure 2 and Figure 3 , further, the rear arm body 6 includes a rear arm 1 601, an insertion rod 602 is installed at one end of the rear arm 1 601 away from the rotating rod 5, and the insertion rod 602 is inserted into the slot in the rear arm 2 605;

[0034] Specifically, two rotating rods 5 are provided, front and rear, and each rotating rod 5 is rotatably connected to two rear arm bodies 6. A stopper is provided at the connection between the rotating rod 5 and the rear arm body 6 to prevent the rear arm body 6 from sliding downward.
