[0004] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme:

[0008] A further improvement is that the moving seat drive assembly includes a power source installed below the mechanism base, a cylindrical shaft located below the mechanism base, and a connecting column fixedly connected to the bottom surface of the pre-pressurized moving seat.
[0009] A further improvement is that the power source is a servo motor, the output end of the servo motor is connected to a cylindrical shaft, and a linear bearing matching the cylindrical shaft is provided in the middle of the connecting column, and the linear bearing is sleeved on the cylindrical shaft.
[0010] A further improvement is that the power source can also be a drive cylinder, in which case the output end of the drive cylinder is fixedly connected to a cylindrical shaft, and there is no linear bearing on the cylindrical shaft; the connecting column is directly fixedly connected to the cylindrical shaft.

The first position sensor can detect the start and end points of the movement, and the second sensor can detect the position of the moving base in real time to ensure the position of the pre-pressure.
