Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] In this embodiment, the transmission mechanism 3 includes a lead screw 3-1 and a lead screw nut threadedly connected to the lead screw 3-1, and the drive plate 5 is disposed on the lead screw nut.

[0018] In this embodiment, the transmission mechanism 3 further includes a bearing seat 3-2, which is disposed on the base plate 1, and the two ends of the lead screw 3-1 are disposed in the bearings of the bearing seat 3-2.

[0019] In this embodiment, the driving mechanism is a motor, and the lead screw 3-1 is mounted on the power output shaft of the motor via a coupling.

[0020] In this embodiment, the drive plate 5 is provided with a guide rail 5-1, and the displacement direction of the guide rail 5-1 and the drive plate 5 has an angle N. The sliding platform 4 is provided with a sliding groove 4-3 that cooperates with the guide rail 5-1, and the displacement direction of the sliding groove 4-3 and the drive plate 5 also has an angle N.

[0021] In this embodiment, the limiting mechanism 2 includes rollers 4-5 on the sliding platform 4, support columns 7 on the base plate 1, and baffles 8 on the top surface of the support columns 7. The rollers 4-5 are located on both sides of the sliding platform 4 in the direction of movement of the drive plate 5 and are mounted on the support columns 7.

[0022] In practical use, the sliding platform is also provided with a mounting groove 4-1 for mounting the roller mounting component 4-4 and the mounting roller 4-5.

[0025] The advantage of this invention is that a small displacement of the upper part can be achieved through bottom displacement. With an angle of 3 degrees (N), the displacement ratio is 1:20, meaning a 0.2mm movement at the bottom corresponds to a 0.01mm movement at the top. This allows for more precise adjustment and provides more accurate data for processing and experimentation. Positions for motor mounting and manual rollers on the shaft are provided, allowing for both electric and manual operation.
