[0008] Furthermore, mounting holes are provided at the four corners of the bottom plate, and a reinforcing block is provided between the fixing plate and the bottom plate.

[0009] Furthermore, the central shaft is rotatably mounted on the fixed plate via a bearing, and reinforcing rods are fixedly connected to both sides of the central shaft, and the other end of the reinforcing rods is fixedly connected to the U-shaped frame.

[0010] Furthermore, one of the electric push rods is fixedly mounted on the output end of the rotary cylinder, and the other electric push rod is rotatably mounted on the mounting seat.

[0011] Furthermore, the two sides of the outer part of the rectangular frame are symmetrically fixed with limit strips, the back of the fixing plate is symmetrically fixed with two limit posts, and the limit posts are provided with limit grooves matched with the limit strips.

[0012] The advantages of the utility model compared with the existing technology are: the utility model enables the rectangular frame to drive the rack to move through the extension and retraction of the electric push rod 2, and the rack drives the central axis to drive the U-shaped frame to rotate through the gear, so that the U-shaped frame can be adjusted to a vertical or horizontal state, so that the device itself can be used on horizontal and vertical processing equipment, and has a wide range of applications.
