[0026] As a technical optimization solution of the present utility model, a rotating structure 3 is provided on the support frame 1. The rotating structure 3 includes a fixed seat 301, a rotating shaft 302 is fixedly connected to the fixed seat 301, the rotating shaft 302 is rotatably connected to the rear plate 202, a threaded rod 303 is rotatably connected inside the rear plate 202, a threaded block 304 is threadedly connected to the threaded rod 303, the threaded block 304 is slidably connected to the rear plate 202, a clamping block 305 is fixedly connected to the bottom end of the threaded block 304, and a clamping groove 306 is provided on the rotating shaft 302; the threaded rod 303 is in a cylindrical structure, and the threaded block 304 is in a multi-prism structure; the clamping block 305 is engaged with the clamping groove 306, and the cross-section of the bottom end of the clamping block 305 is in a semi-circular structure; thus, it is convenient to drive the clamping block 305 to engage with the clamping groove 306 by moving the threaded block 304 to limit the rear plate 202.

[0027] As a technical optimization solution of the present utility model, a rotating rod 307 is fixedly connected to the bottom end of the rotating block 205. The rotating rod 307 is rotatably connected to the rear protection plate 204, the rotating rod 307 is slidably connected to the rear plate 202, a limiting block 308 is fixedly connected to the bottom end of the rotating rod 307, a limiting groove 309 is provided on the threaded rod 303, and the limiting block 308 is engaged with the limiting groove 309; the rotating rod 307 is in a cylindrical structure, the limiting block 308 is in a multi-prism structure, and the limiting groove 309 is in a multi-prism groove structure; thus, it is convenient to disengage the fixed column 206 from the fixed groove 207 and at the same time disengage the clamping block 305 from the clamping groove 306 to release the limit on the rear plate 202.

[0028] When the utility model is in use, first, when it is necessary to transfer materials, if it is necessary to place materials with a relatively high height, the rotating blocks 205 at both ends of the rear baffle 204 can be rotated, so that the fixing columns 206 at the bottom side of one end of the rotating block 205 are engaged with the fixing grooves 207 on the two side baffles 203, connecting the two side baffles 203 and the rear baffle 204. Subsequently, the motor externally connected to the worm 210 drives the worm 210 to rotate, and drives the lead screw 208 in the two side plates 201 to rotate through the engagement of the worm 210 and the worm wheel 211 at the bottom end of the lead screw 208. When the lead screw 208 rotates, through the threaded connection between the lead screw 208 and the side baffle 203 and the limit of the guide rod 209 on the side baffle 203, the side baffle 203 can be driven to slide upward in the side plate 201, and the height of the side baffle 203 can be adjusted according to the height of the material. Moreover, when the side baffle 203 rises, the rear baffle 204 and the side baffle 203 can be driven to rise synchronously through the engagement of the fixing column 206 and the fixing groove 207. When placing materials, the two side baffles 203 and the rear baffle 204 are used to protect the materials to prevent the materials from tipping over. When the heights of the side plate 201 and the rear plate 202 themselves meet the requirements for placing materials, the worm 210 can be reversed, and the lead screw 208 is driven to rotate through the engagement of the worm wheel 211 and the worm 210, and then the side baffle 203 and the rear baffle 204 are driven to descend and reset. When the rear baffle 204 descends, the rear baffle 204 can drive the rotating block 205 and the rotating rod 307 on the rotating block 205 to move together. After the rear baffle 204 is reset, the multi-faceted limiting block 308 at the bottom end of the rotating rod 307 can be engaged with the multi-faceted groove limiting groove 309 on the threaded rod 303. At this time, the clamping block 305 at the bottom end of the threaded block 304 is engaged with the clamping groove 306 on the rotating shaft 302 to limit the rear plate 202, preventing the rear plate 202 from rotating and opening when placing materials, which threatens the safety of workers. When the length of the material to be placed is relatively long and it is inconvenient to place the material due to the obstruction of the rear plate 202, the side baffle 203 and the rear baffle 204 can be adjusted to the reset state. At this time, the multi-faceted limiting block 308 at the bottom end of the rotating rod 307 is engaged with the multi-faceted groove limiting groove 309 on the threaded rod 303. Rotate the rotating block 205 to drive the fixing column 206 to no longer be engaged with the fixing groove 207. When the rotating block 205 rotates, the threaded rod 303 is driven to rotate through the engagement of the limiting block 308 at the bottom end of the rotating rod 307 and the limiting groove 309 on the threaded rod 303. Then, the threaded block 304 is driven to move upward through the threaded connection between the threaded rod 303 and the threaded block 304, so that the clamping block 305 at the bottom end of the threaded block 304 no longer engages with the clamping groove 306 on the rotating shaft 302 and no longer prevents the rear plate 202 from rotating. At this time, the fixing column 206 also no longer engages with the fixing groove 207 on the side baffle 203 and no longer limits the rear plate 202 from above. At this time, the rear plate 202 can be rotated to make the rear plate 202 lie flat, facilitating the entry of materials with a relatively long length between the two side plates 201 from the rear plate 202.
