[0039] Referring to Figures 5-9As shown, the sealing machine housing 11 is provided with a containing groove 116 on the side wall, and a buckle detection device 40 is arranged in the containing groove 116. The buckle detection device 40 comprises a sliding block 41 arranged in the containing groove 116. One side of the sliding block 41 is connected with a compression spring 42, and the other end of the compression spring 42 abuts against the inner side wall of the sealing machine housing 11.
