Description

Technical Field

[0001] The invention relates to a cutting type manual wire stripping device. Background Art

[0002] As a kind of electric wire for connection, it is usually necessary to peel off the protective skin of the wire head to expose the metal wire inside to obtain a connecting wire head, and then connect the connecting wire head to an external appliance or external wire. At present, there are many kinds of wires on the market. Some thicker and harder wires generally have thicker and harder metal wires inside. In order to facilitate the connection of external appliances or external wires, the wire heads are generally set longer, that is, the stripping time is longer. However, the common wire stripping tools such as wire strippers cannot effectively meet the stripping requirements, and the stripping efficiency is low. Summary of the invention

[0005] The wire stripping device in the present application, when in use, inserts the thick and hard wire into the fixed sleeve and the second rotating sleeve in turn, and fixes the wire through the fixed sleeve, holds the fixed sleeve with one hand, and then presses the pressing part with the other hand, so that the cutting knife enters the inner hole of the second rotating sleeve in a radial direction and contacts the protective skin of the wire, and then the sliding knife seat is axially moved back and forth repeatedly to make the cutting knife cut the protective skin, and after the protective skin is cut, the wire is removed from the fixed sleeve and the second rotating sleeve, and then cut with scissors or directly torn off; in the present application, the fixing effect of the fixed sleeve is conducive to holding the wire by hand, which is conducive to improving the wire stripping efficiency, and the second rotating sleeve and the fixed sleeve are coaxially arranged and rotatably connected, and the worker can rotate the second rotating sleeve by a certain angle according to the needs to cut the protective skin again, so that the protective skin is cut into multiple pieces, which is conducive to further improving the stripping efficiency, and at the same time, the entire second rotating sleeve only has one tool sliding groove, which is less destructive to the structure of the second rotating sleeve, and the overall structure is stronger and has a longer service life.

[0006] Preferably, the reset mechanism includes a reset spring disposed in the radial adjustment groove and connected to the limit portion, a guide rod sleeved in the reset spring and having one end passing through the limit portion, and the other end of the guide rod is connected to a connecting plate that can slide axially in the radial adjustment groove. This arrangement allows the cutter to reset back to the cutter sliding groove after cutting the protective skin, thereby preventing the metal wire from being scratched.

[0007] Preferably, the limiting portion is provided with a guide rod through hole for mounting the guide rod.

[0008] Preferably, the stripping knife can extend axially beyond the end surface of the second rotating sleeve. This arrangement is intended to enable the stripping knife to cut the end of the protective skin to improve the wire stripping efficiency.
