[0018] The present invention provides an extrusion component, which can compress the first elastic airbag based on the connecting plate when the output end of the electric telescopic cylinder retracts, causing the second elastic airbag to expand. The extrusion seat moves inside the driving wheel, gradually extruding the sliding rod outward, so that the anti-slip part is close to the rotating seat to facilitate transmission through friction.

[0019] In the present invention, when the output end of the electric telescopic cylinder is extended, the gas is replenished into the first elastic airbag. Based on the contraction of the second elastic airbag, the extrusion seat reduces the degree of extrusion on the sliding rod, so that the anti-slip part is separated from the rotating seat. At this time, the rotating seat can rotate, so that when the positioning column is inserted into the positioning groove, if the positioning plate is skewed, it can be easily corrected, which helps to accurately position the positioning plate and improves reliability.

[0020] The present invention sets a rotation sensor assembly, which can use the rotation sensor assembly to detect whether the rotation angle of the rotating rod meets the requirement, so as to control the positioning part to perform positioning, or timely discover abnormal situations, that is, the driving part fails to rotate to the corresponding angle after working, so as to facilitate timely resolution and improve reliability.

Based on the operation of the extrusion component, the clutch state of the anti-slip part and the rotating seat 15 is adjusted, and then the driving component is operated to drive the various anti-slip parts on the driving wheel 29 to move, thereby realizing the flipping drive of the photovoltaic frame 2.
