Then, by starting two motors (four), the two screws (two) are driven to rotate. The two motors (four) can bring the two positioning plates (two) and the four clamping plates and the two triangular shovels closer to each other through the two U-shaped plates. Then, by starting motor (two), the output shaft of motor (two) drives the reciprocating screw (one) to rotate, and the two clamping plates can be brought closer to each other through the two sliding plates (two). The air source heat pump cooling and heating unit can be clamped. At the same time, through the two The triangular shovel can support the air source heat pump cooling and heating unit, and then start the motor three to drive one of the sprockets eight to rotate.
