[0002] The detachable foot assembly is a furniture part that is convenient to disassemble and assemble, and is mainly used for the support structure of furniture such as chairs. The detachable foot assembly is usually composed of a five-star foot and a plurality of detachable feet in the shape of a tube and penetrating front and back. The five-star foot includes a cylindrical fixing sleeve and a plurality of hollow tubular mounting feet. The detachable foot is sleeved on the other end of the mounting foot and is detachably fixedly connected with the mounting foot. This structure makes the detachable foot have the advantages of convenient disassembly and assembly and facilitation of transportation. However, in the actual production process, the center hole processing of the five-star foot has always been one of the key links restricting product quality.

[0003] The five-star foot is connected with a water gate material formed by injection molding after injection molding. The water gate material needs to be cut off first in the post-processing process of the five-star foot. The existing water gate waste cutting process is mainly in the form of manual operation. The worker needs to place the five-star foot in a fixed processing position and then use a handheld tool to cut. Although this method is simple and easy to implement, it has low processing efficiency, high labor intensity, and safety hazards in the operation process. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the present application provides a five-star foot waste cutting device that can automatically cut off the water gate waste of the five-star foot, thereby improving the processing efficiency.

Start the driving member to drive the cutter 12 to move downward, and the wavy blade 121 of the cutter 12 can effectively cut the irregularly shaped nozzle waste. The first sensor 14 and the second sensor 15 monitor the state of the five-star foot and the cutter 12 in real time to ensure the safety and accuracy of the processing process.
