Description

Technical Field

[0001] The utility model relates to the technical field of wire strippers, in particular to a multi-purpose wire stripper. Background Art

[0002] Wire strippers are common tools in power repair and maintenance. They are used by electricians to strip the surface insulation layer of the wire head. They generally have the basic functions of cutting and clamping. They can cut, clamp and pull the insulation layer on the surface of the wire. At the same time, multi-purpose wire strippers also have the function of cutting the inner core wire ends of the wire, and there is no need to keep changing scissors to cut it.

[0003] The current multi-purpose wire strippers have both cutting and stripping functions. When stripping the outer skin of the wire, the outer skin of the wire is cut through the wire stripper cutting groove, and the wire stripper is pulled to one side to strip off the outer skin. However, this operation method may damage the inner core of the wire and may affect its stripping efficiency. Utility Model Content

[0013] Beneficial effects:

[0014] 1. The multi-purpose wire stripper cuts the outer skin of the wire through the cutting groove. At the same time, when the cutting groove contacts the wire, the jacket clamps the front end of the wire, and drives the driving plate to move through the second inclined surface on the driving platform. The driving plate drives the slide bar to slide toward the end close to the end of the wire. At this time, the tension spring is stretched by force, and the slide sleeve always applies a certain force to the jacket through the connecting rod. When the cutting groove completely cuts the outer skin of the wire, the outer skin of the wire after cutting is directly fallen off under the action of the tension spring, the slide sleeve, the connecting rod and the jacket, thereby effectively improving the efficiency of wire stripping and effectively preventing the inner core of the wire from being damaged when the outer skin is pulled to one side after cutting.

[0015] 2. The multi-purpose wire stripper effectively improves the friction between the wire and the outer skin by arranging the friction pad, thereby facilitating the removal of the outer skin of the wire and effectively preventing the jacket from excessively squeezing the wire and affecting the stripping process.

[0016] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model effectively improves the efficiency of wire stripping and effectively prevents the inner core of the wire from being damaged when the outer skin is pulled to one side after cutting.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Example 1: Reference Figure 1-Figure 5 A multi-purpose wire stripper comprises: two pliers 1, and also comprises: a limit pin 104, which penetrates the two pliers 1, and the two pliers 1 are rotatably connected to the limit pin 104; a cutting head 2, which is fixed on the pliers 1, and the two cutting heads 2 match; a plurality of cutting grooves 201, which are equidistantly arranged on the cutting head 2; a plurality of sliding rods 3, which slide on the cutting head 2 at an equal distance, and the sliding rods 3 match the cutting head 2; a sliding sleeve 401, which slides on the sliding rod 3; a connecting rod 402, which is fixed on the sliding sleeve The sleeve 401 is on the connecting rod 402; the sleeve 4 is fixed on the connecting rod 402, and the two adjacent sleeves 4 match each other, and the sleeve 4 matches the cutting groove 201; the limiting piece 303 is fixed on one end of the sliding rod 3, and a tension spring 304 is fixedly connected between the limiting piece 303 and the sliding sleeve 401; it is used to drive the sliding rod 3 to slide in the driving assembly; the first inclined surface 202 is arranged at the cutting groove 201 of the cutting head 2; the cutting part 203 is arranged at one end of the cutting head 2 close to the limiting pin 104.

[0025] The driving assembly includes a driving plate 301 fixed between multiple sliding rods 3, and the end of the cutting head 2 is fixedly connected to a driving platform 404 matching the driving plate 301. The driving platform 404 is provided with a second inclined surface 405 matching the driving plate 301, and a first spring 302 is fixedly connected between the driving plate 301 and the cutting head 2.

[0026] The driving plate 301 is provided with a rounded corner 305 matching the driving platform 404 .

[0027] A friction pad 403 is fixedly connected inside the jacket 4 .

[0028] When stripping the wire, first put the wire into a suitable cutting groove 201, hold the pliers body 1 to rotate the cutting head 2 along the axis of the limit pin 104, and cut the outer skin of the wire through the two opposite cutting grooves 201. At the same time, when the cutting groove 201 contacts the wire, the jacket 4 clamps the front end of the wire, and drives the driving plate 301 to move through the second inclined surface 405 on the driving platform 404, and the driving plate 301 drives the slide bar 3 to slide toward the end close to the end of the wire. At this time, the tension spring 304 is stretched by the force, and the sleeve 401 always applies a certain force to the sleeve 4 through the connecting rod 402. When the cutting groove 201 completely cuts the outer skin of the wire, the outer skin of the wire after cutting is directly fallen off under the action of the tension spring 304, the sleeve 401, the connecting rod 402 and the jacket 4, thereby effectively improving the efficiency of wire stripping and effectively preventing the inner core of the wire from being damaged when the outer skin is pulled to one side after cutting.

[0029] If the wire core has a shielding layer, the shielding layer is cut by the cutting part 203 .

[0030] The first inclined surface 202 on the cutting groove 201 facilitates pushing the cut outer skin of the wire to a side close to the end of the wire for a distance, thereby effectively improving the peeling effect.

[0031] By providing the friction pad 403, the friction force between the jacket and the outer skin of the wire is effectively increased, thereby facilitating the removal of the outer skin of the wire, and effectively preventing the jacket 4 from excessively squeezing the wire and affecting the stripping process thereof.

[0032] The diameters of the plurality of cutting grooves 201 become smaller in sequence.

[0033] Example 2: Reference Figure 1-Figure 5 A multi-purpose wire stripping pliers is basically the same as the embodiment 1, and further, a sheath 101 is fixedly connected to the pliers body 1, and an arc spring 102 is fixedly connected between the two sheaths 101.

[0034] A push rod 103 is fixedly connected to the sheath 101 , and two adjacent push rods 103 match each other.

[0035] By arranging the arc spring 102 between the sheaths 101, the clamp body 1 can be automatically reset after one stripping process, so as to facilitate the next stripping process and effectively improve the stripping efficiency.

[0036] By providing the push rod 103, it is possible to effectively prevent the wire from being cut excessively and causing damage to the inner core of the wire.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
