The utility model discloses a split-type reed clip for a small-sized tubular stapler, which comprises a upper clip reed and a lower clip reed connected to the lower end of the upper clip reed, and the upper clip reed and the lower clip reed have the same cross-sectional outer diameter. The upper clasp reed is a tubular structure with upper and lower through the insertion holes in the middle, and a symmetrically arranged clasp reed is arranged on the tube wall of the upper clasp reed. The lower clarinet is a rod like structure. The upper end of the lower clip reed is provided with a connecting platform, which is a cylindrical convex platform structure whose cross-sectional diameter is less than the lower clip reed. The lower end of the lower clip reed pipe is provided with a clip connection groove which penetrates both sides of the lower clip reed pipe and has an opening downward, and the lower clip reed pipe on both sides of the clip connection groove is provided with a penetrating pin shaft hole. The upper end of the lower clarinet is connected with the insertion hole at the lower end of the upper reed pipe through the connecting table. The utility model divides the clasp reed tube into upper clasp reed tube and lower clasp reed tube. The single length is shorter, the machining is easier, the processing stability is better, the processing of the lower solid rod structure is simpler, and the processing yield is improved.
