[0054] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0062] The rotating assembly 31 includes a rotating outer tube 311 rotatably disposed in the hole 116 of the partition plate and sleeved on the lower cylinder 131, and a driving gear 312 formed on the rotating outer tube 32 above the horizontal partition plate 115, and a driven rack 23 is meshed in front and rear of the driving gear 312 respectively;

[0071] This solution can automatically clamp the track 9 and realize the automatic centering of the target 8:

[0078] Rotating the height-adjusting spindle 51 and the externally threaded rod 53 drives the internally threaded tube 54 and the anti-rotation longitudinal hole 55 to move along the anti-rotation longitudinal rod 134 , and drives the longitudinal beam 41 , the transverse wheel axle 42 , and the height-limiting roller 43 to move in the longitudinal direction relative to the frame 1 .
