[0017] The utility model has the advantages of the following:

[0018] 1. Rotating the lead screw on one side inside the connecting cylinder causes the lead screw to rotate and move the blocking block to the top.

During use, the blocking block can be adjusted to different distances from the bottom of the extrusion tube, effectively adjusting the pressing height of the extrusion tube. This allows for adjustment of the space between the bottom of the extrusion tube and the top of the feed tube that can be compressed in one press, thereby adjusting the amount of material extruded in one press. Simultaneously, rotating another lead screw causes it to move the moving block, which in turn moves the connecting ring. This causes the connecting ring to push the compression spring at the top, adjusting the compression degree of the compression spring. This allows for adjustment when the compression spring is loose or has excessive elasticity, facilitating extrusion.

[0019] 2. By rotating the rotating plate around the rotating axis, the angle of the rotating plate can be adjusted, thereby adjusting the position and angle of the extrusion nozzle to meet different extrusion needs. At the same time, the extrusion nozzle can be pulled, which in turn moves the slide rod. Through the mutual sliding between the slide rod and the inside of the rotating plate, the position of the extrusion nozzle can be easily adjusted. Furthermore, the extrusion nozzle can be pulled further, causing the slide rod to disengage from the inside of the rotating plate, and thus the extrusion nozzle to disengage from the rotating plate. At this point, the extrusion nozzle can be easily moved to any position through the connection between the delivery pipe and the extrusion nozzle, making it convenient for users to press and use without moving the entire device.

[0034] Working principle: in use, the top connecting plate 4 can be pressed to drive the connecting plate 4 to move the bottom extrusion pipe 301 through the bottom connecting pipe 3, thereby extruding the spring 502 and reducing the space between the bottom of the extrusion pipe 301 and the top of the feeding pipe 2, so that the material can be extruded into the connecting pipe 3 through the connecting pipe 5, and then transported to the position of the extrusion nozzle 6 through the conveying pipe 601 at the top of the connecting pipe 3, thereby realizing extrusion.

Another screw 101 can also be rotated to drive the moving block 203 to move, thereby moving the connecting ring 201 to push the extrusion spring 502 at the top and adjust the extrusion degree of the extrusion spring 502, thereby adjusting the extrusion when the extrusion spring 502 is loose or the elastic force is too high.

[0035] During use, the rotating plate 401 can be rotated around the rotating shaft 402 to adjust the angle of the rotating plate 401, thereby adjusting the position angle of the extrusion nozzle 6 to meet different extrusion needs.
