[0024] Furthermore, a bearing 7 is installed in the middle of the upper arm 1, and is rotatably connected to the first transverse slider 303 through the bearing 7. While the upper arm 1 moves in a straight line with the first transverse slider 303, it can also rotate relative to the transverse mechanism 3 around the bearing 7.

[0025] Specifically, such as Figure 6 As shown, the second screw adjustment mechanism 6 includes a second adjusting screw 601 and a second cylindrical spring 602 sleeved and installed on the second adjusting screw 601; one end of the second adjusting screw 601 is provided with a slider bracket 603, which is connected to the second transverse slider 304 through the slider bracket 603; the other end is provided with a pin seat 604, which is rotatably connected to the end of the large arm 1 through a first pin 605.

[0026] In this embodiment, an adjusting nut is provided at one end of the second adjusting screw 601 near the slider bracket 603. By turning the adjusting nut, the second adjusting screw 601 moves in a straight line, thereby driving the upper arm 1 to rotate around the bearing 7, so as to adjust the angle of the upper arm 1.
