[0022] The horizontal moving device 201 is specifically a rodless cylinder, and is used to drive the rotating disc 203 to perform a horizontal moving action. A pulley 302 is rotatably connected to a lower part of the positioning seat 301, and an arc surface is arranged on a side of the position matching slope plate 4 close to the positioning seat 301. When performing a reversing feeding action, the rotating disc 203 and the seat plate 3 will perform a rotating reversing action under the action of the guide seat 202 and the guide rod 204 during the horizontal moving process of the seat plate 3, and the pulley 302 is tangent to the arc surface of the position matching slope plate 4.

[0023] A positioning groove is arranged on the positioning seat 301, and is used to position a folding angle support 8. The clamping assembly 5 comprises a cylinder seat 501, a limiting cylinder 502, and a folding angle limiting rod 503. The extension and retraction of a piston rod of the limiting cylinder 502 is used to drive the folding angle limiting rod 503 to perform a horizontal moving action, and a conical surface is arranged at an end of the folding angle limiting rod 503, so that the folding angle support 8 can be better positioned. The extension and retraction of the piston rod of the limiting cylinder 502 is used to drive the folding angle limiting rod 503 to perform a limiting action.
