The protective sleeve 63 is sleeved on the end of the rotating rod 61 away from the hinge shaft 62. The cutting assembly 7 includes two cutting knives 71, one cutting knife 71 corresponds to a rotating rod 61, the cutting knife 71 is located at one end of the rotating rod 61 close to the hinge shaft 62, the cutting knife 71 and the rotating rod 61 are integrated, the rotating rod 61 drives the cutting knife 71 to move, when the coil lead head needs to be cut, the person holds the rotating rod 61, moves the cutting knife 71 close to the lead wire that needs to be cut, and places the lead wire between the two cutting knives 71, and the person moves the two rotating rods 61 toward each other, and the two cutting knives 71 can cut the lead wire.

[0009] By adopting the above technical solution, when it is necessary to use the pneumatic shearing tool for the coil lead head, first, connect the drive component to the external power supply, then move the coil lead pneumatic shearing tool close to the lead head that needs to be cut, so that the lead head that needs to be cut is located between the two shearing knives, and then start the drive component. The drive component drives the pusher to slide along the axis of the outer cylinder, and the pusher can drive the two shearing handles to move toward each other. At the same time, the shearing knives move synchronously with the shearing handles, and the two shearing knives can move toward each other. The two shearing knives can cut the lead head. After the cutting is completed, start the drive component again, and the drive component The part drives the pushing part to move, and the pushing part moves toward the side away from the cutting handle. At this time, the two cutting handles move toward the side away from each other, which can drive the two cutting knives to move toward the side away from each other. According to the above steps, the remaining lead heads can be cut. Compared with the related art, the present application brings the pneumatic cutting tool of the coil lead head close to the lead head so that the lead head is located between the two cutting knives, and then starts the driving component. The driving component drives the pushing part to move, which can drive the two cutting knives to move toward or away from each other, thereby cutting the lead head without manual cutting. This is beneficial to improving the problem of increased labor intensity of personnel.

[0010] Optionally, the pushing member includes a pushing rod, which is coaxially arranged with the outer cylinder, and a conical groove is provided on the side of the pushing rod close to the shear handle for the two shear handles to extend into, and the diameter of the conical groove gradually decreases along the axial direction of the outer cylinder from the shear handle toward the side away from the shear handle, and the driving assembly is connected to the pushing rod.

[0011] By adopting the above technical scheme, when it is necessary to cut the lead head, start the driving assembly, and the driving assembly drives the push rod to move in the outer cylinder toward the cutting handle until the two cutting handles extend into the conical groove, and continue to start the driving assembly, and the driving assembly continues to drive the push rod to move. At this time, the two cutting handles can slide in the conical groove toward the side away from the cutting handles. During the movement of the cutting handles, the two cutting handles move toward each other, and the shearing knives move synchronously with the cutting handles. The two cutting knives can cut the lead head. The conical groove is provided on the pushing rod, which facilitates the connection between the pushing rod and the cutting handle. When the cutting handle extends into the conical groove, the two cutting handles can be moved during the movement of the pushing rod, which is conducive to the pushing rod pushing the cutting handles to move, and further helps to improve the problem of increased labor intensity of personnel.

[0012] Optionally, the end of the shear knife away from the shear handle is blade-shaped, the shear knife is inclined from the shear handle to the shear knife toward a side away from the shear knife, and the two shear knives are inclined toward a side close to each other.

[0013] By adopting the above technical solution, when the lead head is located between the two shear knives, the driving assembly can drive the shear handles to move toward or away from each other. During the movement of the shear handles, the shear knives move synchronously with the shear handles. The side of the shear knife away from the shear handles is in the shape of a blade, which facilitates cutting of the lead head.

[0014] Optionally, an adjustment component is also included, which includes two adjustment bolts, one of which corresponds to one of the shear handles, and the adjustment bolt passes through the outer cylinder and abuts against the side of the shear handle close to the outer cylinder, and the adjustment bolt is threadedly connected to the outer cylinder.

[0015] By adopting the above technical scheme, when it is necessary to cut the lead head, when the thickness of the lead head to be cut is relatively thick, the personnel screw the two adjusting bolts at the same time, and the adjusting bolts are separated from the cutting handles. At this time, the two cutting handles rotate away from each other, and the two cutting knives rotate away from each other, and the distance between the two cutting knives becomes larger, until the two cutting knives are adjusted to a suitable position so that the lead head is located between the two cutting knives. When the thickness of the lead head to be cut is relatively thin, the personnel screw the adjusting bolts in the opposite direction, and the adjusting bolts push the cutting handles to move toward each other, and the distance between the chain cutting knives becomes smaller. By setting the adjustment component, on the one hand, the distance between the two cutting knives can be adjusted to facilitate the cutting of lead heads of different thicknesses; on the other hand, the adjusting bolt abuts against the cutting handle, which is convenient for positioning the cutting handle and is conducive to the cutting handle extending into the conical groove.

The driving component continues to push the push rod to move. At this time, the reset spring is compressed, and then the shear handle can be extended into the conical groove, so that the two shear knives can shear the lead head. After the two shear knives have completed the shearing, the reset spring restores its deformation. At this time, the reset spring can drive the push ring to move toward the side away from the shear handle. By setting the reset spring, the push rod can be moved after the lead head is sheared.
