The first rotational force can be given by the power of the drive motor 380 as well as the first rotational force.

The driving motor 380 may be a servo motor. The servomotor has a built-in variable resistor for measuring the rotation angle of the motor, and can be rotated by a desired angle according to the duty ratio of the input pulse. Therefore, the output from the control module 390 It is possible to follow the accurate position and speed according to the control signal.

In addition, the drive motor 380 may be a general AC motor or a stepping motor in consideration of the manufacturing cost.

The control module 390 may control the rotation speed of the driving motor 380 by varying the frequency of the driving motor 380 when power is applied to the driving motor 380. The control module 390 may include various protection circuits for stable power supply and may include a plurality of operation buttons for user operation.

As described above, the height of the first support portion 30 can be easily adjusted by the length adjusting means. By adjusting the height of the front end of the main plate 10, the first support portion 30 can be closely attached to the loading space 1, .
