Description

Technical Field

[0001] The utility model relates to an electrician's tool, in particular to a small-sized wire stripper which is easy to carry. Background Art

[0002] At present, there are many types of wire stripping tools, but ordinary electricians usually use wire stripping pliers. It is easy for wire stripping pliers to handle wires with small wire diameters and short stripping lengths. However, in some electrical operations, large wire diameters or long stripping lengths are often encountered, and ordinary wire stripping pliers are powerless. The utility model patent with application number 201921600159.1 discloses "a waste wire stripping machine", which can be used to strip the outer skin and core of the wire. It is mainly used for stripping waste wires and has a good use effect. However, since it is aimed at waste wires, it does not consider the damage to the core during stripping. In terms of structure, it adopts a design of a guide wheel and a blade, and the cutting depth of the blade is not easy to adjust. When the blade cuts the outer skin of the wire, it will also go deep into the core and scratch the core. Therefore, it is not suitable for normal wire stripping during wire laying operations. Summary of the invention

[0003] The technical problem to be solved by the utility model is: in view of the above problem, a portable wire stripper with good use effect is provided.

[0004] The technical solution of the utility model is: a wire stripper, comprising a bracket, a guide wheel and a blade, the circumference of the guide wheel ring is provided with a "V" groove, the bracket is a rectangular frame composed of a plate material, the side plates on both sides of the bracket are provided with vertically arranged sliding grooves, the guide wheel is rotatably arranged on the bracket below the sliding groove through a guide wheel shaft, a "door"-shaped adjustable knife holder is provided above the guide wheel, a wire pressing wheel is provided at the bottom of the adjustable knife holder, the wire pressing wheel is composed of two wheels that can rotate independently and are spaced at a certain gap, the wheel axle of the wire pressing wheel is parallel to the guide wheel shaft, and its two ends extend from the side of the adjustable knife holder and extend into the sliding grooves of the side plates on both sides of the bracket, the blade is arranged in the gap in the middle of the wire pressing wheel, the tip of the blade faces the middle position of the guide wheel, the top end of the bracket is screwed with an adjusting bolt, and the bottom of the adjusting bolt is rotatably connected to the top of the adjustable knife holder.

[0005] The technical effect of the utility model is that it has the advantages of simple structure, small size, easy to push and use. The wire diameter and stripping depth of the wire can be adjusted, and it is suitable for stripping common wires. It can be operated manually or driven by electric tools such as electric drills to complete the stripping of wires. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 2It is a structural schematic diagram of the adjustable tool holder part of the utility model. DETAILED DESCRIPTION

[0008] like Figure 1 and 2 As shown, a wire stripper comprises a bracket 1, a guide wheel 2 and a blade 3. The guide wheel 2 is provided with a "V" groove on its circumference. The "V" groove can play a role in aligning the tip of the knife. The bracket 1 is a rectangular frame composed of a plate material. The side plates on both sides of the bracket 1 are provided with vertically arranged slide grooves 4. The guide wheel 2 is rotatably arranged on the bracket 1 below the slide groove 4 through a guide wheel shaft 5. An adjustable knife holder 6 in the shape of a "door" surrounded by a top edge and two side edges is provided above the guide wheel 2. A wire pressing wheel 7 is provided at the bottom of the adjustable knife holder 6. The wire pressing wheel 7 consists of two wheels that can rotate independently and are spaced apart by a certain gap. The wheel axle 8 of the wire pressing wheel 7 is parallel to the guide wheel shaft 5, and its two ends extend from the side edges of the adjustable knife holder 6 and extend into the slide grooves 4 of the side plates on both sides of the bracket 1. The blade 3 is arranged in the gap in the middle of the wire pressing wheel 7, and the tip of the knife faces the middle position of the guide wheel 2. An adjusting bolt 9 is screwed on the top of the bracket 1, and the bottom of the adjusting bolt 9 is rotatably connected to the top of the adjustable knife holder 6. Turning the adjustment bolt allows the adjustment knife holder to slide up and down along the slide slot. Insert the wire into the groove between the guide wheel and the wire pressing wheel. The wire pressing wheel can be pressed tightly against the wire by adjusting the bolt, and the tip of the knife can be inserted into the outer skin of the wire. Pulling the wire or turning the guide wheel can slit the outer skin of the wire axially. The bracket and the adjustable knife holder can limit the left and right clearance of the adjustable knife holder by retaining a small gap, or the two ends of the wire pressing wheel axle can be processed into a flat shape, and the left and right clearance of the adjustable knife holder can be limited by matching the step with the inner side of the bracket side plate, so that the axle can only slide up and down, but cannot move forward, backward, left or right.

[0009] A blade fixing portion 10 is provided above the crimping wheel 7, a hole is opened on the wheel shaft 8 of the crimping wheel 7, and a blade 3 is fixed on the blade fixing portion 10 and passes through the hole on the wheel shaft 8 of the crimping wheel 7. The blade can be a wallpaper blade.

[0010] The blade fixing part 10 is vertically provided with a blade fixing hole, which can be opened in three directions for easy disassembly. The blade 3 is fixed to the blade fixing part 10 by a locking screw 11. The length of the blade tip extending can be adjusted by adjusting the position of the blade up and down, so as to more accurately control the depth of the blade tip cutting the outer skin of the wire. The locking screw can be inserted into the tool through the slide slot on the bracket to be twisted.

[0011] The adjacent wheel rims of the two wheels of the crimping wheel 7 are provided with a concave arcuate annular groove. The arcuate annular groove can be used to have greater contact with the wire skin, so that the blade can cut the wire skin more easily.

[0012] One end of the guide wheel shaft 5 extends out of the bracket for a distance as a connection portion with the driving device, so as to facilitate connection with electric tools such as electric drills for driving.

[0013] A handle 12 is provided at the bottom of the bracket 1 .

[0014] The "V"-shaped groove surface of the guide wheel 2 is provided with anti-skid patterns. The anti-skid patterns are arranged transversely along the surface, and can prevent the wire from sliding when driven by an electric tool, so as to ensure stable feeding of the wire.
