[0026] The base 1 is slidably connected with a moving base 4, and both sides of the moving base 4 are fixedly connected with displacement bases 301, and the top of the displacement base 301 is connected with a mounting base 3. Under the action of the displacement base 301, the moving base 4 and the mounting base 3 move more stably on the base 1. The mounting base 3 is provided with:

[0027] The mobile unit includes a positioning seat 5, which is located on both sides of the mounting seat 3. The positioning seat 5 is slidably connected with the mounting seat 3. The mobile unit is used to adjust the distance between the mounting seat 3 and the positioning seat 5. By sliding the positioning seat 5 with the mounting seat 3, the positioning seats 5 on both sides of the mounting seat 3 are adjusted to be in a suitable position;

[0028] The adjusting unit includes a mounting block 6, a rotating rod 601 and a threaded rod 603. The mounting block 6 is slidably connected to the positioning seat 5. The mounting block 6 is rotatably connected to the rotating rod 601. The threaded rod 603 is fixedly connected to the bottom end surface of the positioning seat 5. The rotating rod 601 is slidably connected to the threaded rod 603. The adjusting unit is used to adjust the distance between the mounting block 6 and the positioning seat 5. The rotating rod 601 slides along the threaded rod 603 to push the mounting block 6 to slide relative to the positioning seat 5. When multiple mounting blocks 6 are in appropriate positions, mechanical parts of different sizes are installed through four mounting blocks 6. At the same time, the mechanical parts are supported under the action of the rotating rod 601 to facilitate the stability of the mechanical parts on the mounting seat 3.

[0029] The moving seat 4 is threadedly connected to the driving screw 401 . When the driving screw 401 rotates, the moving seat 4 is controlled to slide on the base 1 , thereby driving the displacement seat 301 and the mounting seat 3 to move.

The bidirectional screw rod 501 is driven to rotate on the mounting seat 3 by rotating the rotating block 504 .

[0031] The bidirectional screw rod 501 is threadedly connected to the positioning seat 5. When the bidirectional screw rod 501 rotates, the positioning seats 5 on both sides of the mounting seat 3 move in opposite directions or toward each other.
