s2, detaching blade 224: firstly, the upset head scissors 22 are integrally pushed out of the inner pipe 21, an operator pulls the tool apron 27 towards two sides, so that the tool holder 221 drives the blade 224 to fall off from the tool apron 27, and at the moment, the connecting shaft 222 of a new tool holder 221 is clamped into the connecting groove 271, and then the blade 224 can be replaced;
s3, adjusting the opening angle of the heading shears 22: an operator pushes the adjusting teeth 23 clockwise to rotate, the adjusting teeth 23 drive the transmission teeth 231 to rotate, the first pulling rope 235 is wound on the rotating shaft 233, at the moment, the other end of the first pulling rope 235 is towards the connecting bar 225 on the stretching heading scissors 22, so that two ends of the connecting bar 225 are attached to the middle position, and two knife handles 223 are driven to be attached to the middle position, so that the angle between the two blades 224 is reduced, otherwise, the operator pushes the adjusting teeth 23 counterclockwise to rotate, the transmission teeth 231 are driven to rotate through the adjusting teeth 23, the first pulling rope 235 is discharged from the rotating shaft 233, the connecting bar 225 on the stretching heading scissors 22 rebounds by utilizing the elasticity of the connecting bar 225, so that two ends of the connecting bar 225 move towards two sides, and the two knife handles 223 are driven to open towards two sides, so that the angle between the two blades 224 is increased, and the angle adjustment of the heading scissors 22;
s4, locking the opening angle of the heading shears 22: an operator pulls the safety rod 24, so that the latch 242 of the safety rod 24 is clamped on the transmission teeth 231, and the transmission teeth 231 are in a locking state, so that the opening angle of the heading shears 22 is fixed, and the heading shears 22 are prevented from being closed during operation;
s5, adjusting the extension length of the heading scissors 22: an operator drives the transmission shaft 251 to rotate by rotating the adjusting head 25, and as the ball screw 253 is connected with the transmission shaft 251 through the connector 254, the transmission shaft 251 rotates to drive the ball screw 253 to rotate, so that the ball screw nut 252 realizes linear motion on the ball screw 253, the position of the tool apron 27 can be changed by changing the position of the ball screw nut 252, and the extending length of the heading shears 22 can be adjusted;
s6, closing heading scissors 22: an operator pulls the operating handle 26, the operating handle 26 presses down and pulls the second pulling rope 262, at the moment, the second pulling rope 262 pulls the mounting column 265, the mounting column 265 is made to incline by the compression spring 264 and the corrugated pipe 266, when the mounting column 265 inclines, the shell 267 clamps the first pulling rope 235 and pulls the first pulling rope 235, at the moment, the other end of the first pulling rope 235 is attached to the connecting strip 225 on the upset head scissors 22, two ends of the connecting strip 225 are attached to the middle position, the two knife handles 223 are driven to be attached to the middle position, the two knife blades 224 are closed, and the closing of the upset head scissors 22 is achieved.
