[0006] 2. In the above scheme, the dispensing unit is a photovoltaic dispensing unit.
[0007] 3. In the above scheme, the guide block and the motor are both mounted on a support frame. The lower support plate of the support frame is mounted on a base plate through at least two spaced columns. The two motors are spaced on the upper surface of the upper support plate of the support frame.
