Preferably, a third gear 8 is arranged between the fourth gear 7 and the limiting chuck 3, the third gear 8 is rotatably connected with a side plate of the frame 1, the fourth gear 7 is in meshed connection with the third gear 8, a tooth space 33 is formed on the outer circumferential side of the limiting chuck 3 and can be meshed with the third gear 8, the fourth gear 7 is a missing gear and has a quarter of tooth number, when the limiting chuck 3 rotates to make the rotating shaft 21 come out of the arc-shaped limiting groove 301, the tooth space 33 drives the fourth gear 7 to rotate through the third gear 8, as shown in fig. 4 and 6, when the rotating shaft 21 completely comes out of the arc-shaped limiting groove 301, the push block 9 extends to the lower side of the molding supporting plate 2 to lift the left end of the molding supporting plate 2, at this time, the limiting chuck 3 is continuously controlled to rotate counterclockwise through the first cylinder 13, at this time the straight inclined plane 3011 of the limiting chuck 3 drives the rotating shaft 21 to move upward and then move leftward, and brings the rack 23 into meshing contact with the fifth gear 10.

In some embodiments, the forming support plate 2 can be manually restored to the initial state, that is, the forming support plate 2 is manually driven to rotate clockwise, but it is relatively laborious, in this embodiment, a next mode is preferably adopted, the end, away from the fixed block 105, of the through hole of the rack 1 is provided with the wire roller shaft 16, the wire roller shaft 16 is wound with the pull rope 17, the end, away from the rack 23, of the bottom surface of the forming support plate 2 is provided with the cable buckle 22, the movable end of the pull rope 17 is tied on the cable buckle 22 by bypassing the guide roller 109, one end of the wire roller shaft 16 is connected with the motor, that is, the wire roller shaft 16 is driven to rotate by the motor, further, the forming support plate 2 is driven to rotate clockwise by the pull rope 17, the adopted motor does not have a self-locking function, that is, the wire roller shaft 16 can rotate forward and backward after the motor is turned off.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", etc., indicating an orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are used merely for convenience in describing the present invention and for simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, or be operated, and thus, should not be construed as limiting the present invention.

Furthermore, the method is simple. The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

It will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the spirit and scope of the invention, and any equivalents thereto, such as those skilled in the art, are intended to be embraced therein.
