A sink groove 105 is provided on the side wall of the rotating shaft 104. A plurality of mounting brackets 106 are connected to the rotating shaft 104. A limiting plate 108 is fixed to the inner wall of the concave mounting bracket 101. A cutting knife 107 is rotatably connected to one end of the mounting bracket 106. The other end of the mounting bracket 106 is set in a Y shape. The Y-shaped end of the mounting bracket 106 is connected to a positioning block 109 through an elastic telescopic component 4. Under the elastic force of the elastic telescopic component 4, the positioning block 109 extends into the sink groove 105. The positioning block 109 and the positioning block 109 are connected to the inner wall of the concave mounting bracket 101. The contact surface of the sinking groove 105 and the inside of the sinking groove 105 are both provided with anti-slip grooves; a limiting mechanism 5 is provided on the rotating shaft 104, and when the rotating shaft 104 drives the mounting frame 106 to rotate toward the battery insulating film, the limiting mechanism 5 limits the movement of the mounting frame 106 on the rotating shaft 104; the limiting mechanism 5 includes a guide groove 501 provided in the mounting frame 106, and a limited sliding rod 502 is slidably connected in the guide groove 501, and one end of the limited sliding rod 502 is fixed with a tension spring 2 503, and the end of the tension spring 2 503 is fixed in the guide groove 501, and the rotating shaft 104 is provided with a plurality of limit grooves 504, and the mounting frame 106 is provided with a transmission assembly 6. When the rotating shaft 104 drives the mounting frame 106 to rotate toward the battery insulating film, the transmission assembly 6 drives the other end of the limit slide bar 502 to cooperate with one of the limit grooves 504. The transmission assembly 6 includes an avoidance groove 601 provided on the limit slide bar 502, and the avoidance groove 601 is provided with an inclined surface 602.

The limiting slide bar 502 overcomes the elastic force of the tension spring 503 and moves. The end of the limiting slide bar 502 is inserted into the limiting groove 504 to further limit the mounting bracket 106 from sliding on the rotating shaft 104, thereby fixing the position of the mounting bracket 106 to prevent the mounting bracket 106 from moving when cutting the battery insulating film; in the present invention, the position of the cutting knife 107 can be adjusted, and the mounting bracket 106 can be self-locked by rotation.

[0030] In an embodiment of the present invention, under the guiding action of the vertical slide groove 301, the compression spring 304 pushes the sliding frame 302 to move, the sliding frame 302 drives the tensioning shaft 303 to move, and the tensioning shaft 303 pushes the battery insulating film, thereby tensioning the battery insulating film, making it easier for the cutting knife 107 to cut the battery insulating film.
