And the left and right tool rests are respectively provided with a wire stripping blade.

And one end of the second vertical section, which is connected with the inclined section, is provided with a roller, the second vertical section is sleeved with an elastic part, two ends of the elastic part respectively abut against the roller and the shell, and the elastic part is a compression elastic part.

The end part of the push rod is provided with a driving wheel which is abutted against the cambered surface and is positioned above the roller.

Due to the adoption of the technical scheme, the problem that potential safety hazards exist due to clamping injury easily caused when the conventional wire stripping is used is effectively solved. Through the arrangement of the connecting piece and the matching of the push rod which is rotatably arranged, when force is continuously applied to the two handles in a single step, the clamping heads are released, the two clamping heads are far away from each other and are unfolded, and a cable or fingers or the like clamped between the cable clamping heads are released from the two clamping heads.

Detailed Description

Referring to fig. 1-6, the anti-pinch wire stripper comprises a shell 1, a first handle 01 and a first chuck 02, wherein the shell 1 comprises a second handle 11 and a second chuck 12, a limiting hole 121 is formed in the second handle 12, the first chuck 02 and the second chuck 12 form a cable chuck 2, a left tool rest 3 and a right tool rest 3 are arranged in the cable chuck 2, a torsion spring is arranged between the left tool rest 3 and the right tool rest 3, and the cable chuck 2 is in an open state under the condition of no external force under the action of the torsion spring, such as the state shown in fig. 1-2; one end, far away from the left knife rest 3, of the first chuck 02 is provided with an arc surface 021, a straight surface 022 and a transition surface 023 which are sequentially connected, and the end is provided with a through hole 024 and an abdicating through groove 025, wherein the abdicating through groove 025 is communicated with the through hole 024; the left and right tool rests 3 are rotatably connected with a connecting piece 4, the connecting piece 4 comprises a first vertical section 41, an inclined section 42 and a second vertical section 43, the connecting piece 4 penetrates through the through hole 121, the second vertical section 43 is inserted into the limiting hole 121, as shown in the attached drawing 4, the first vertical section 41 is parallel to the second vertical section 43, and the first vertical section 41 is rotatably connected with the left and right tool rests 3; the push rod 5 is rotatably connected in the first handle 01, and a torsion spring is arranged between the push rod 5 and the first handle 01.

The left and right knife rests 3 are respectively provided with a wire stripping blade 31.

One end of the second vertical section 43, which is connected with the inclined section 42, is provided with a roller 6, the second vertical section 43 is sleeved with an elastic part 7, two ends of the elastic part 7 are respectively abutted against the roller 6 and the shell 1, and the elastic part 7 is a compression elastic part.

The end of the push rod 5 is provided with a driving wheel 51, the driving wheel 51 is abutted against the cambered surface 021, and the driving wheel 51 is positioned above the roller. As shown in fig. 5, the push rod 5 is bent.

As shown in figure 1, the first chuck 02 is rotatably connected with the shell 1 at a point A, and the first handle is rotatably connected with the shell at a point B. Holding a first handle (01) and a second handle (11) by hand and applying force, as shown in the attached drawing 2, a push rod (5) pushes a first chuck (02) to rotate around a point A to drive a cable chuck (2) to be gradually closed, meanwhile, a left knife rest (3) and a right knife rest (3) in the first handle are gradually closed, when the cable chuck (2) is completely closed and continues applying force to the two handles, the first handle (01) cannot be pushed any more, a driving wheel (51) on the push rod (5) pushes a roller (6) to move downwards along an inclined section (42), the roller (6) drives a connecting piece (4) to continue moving towards a compression elastic piece (7), as shown in the attached drawing 6 and combined with the attached drawing 2, the connecting piece (4) drives the left knife rest (3) movably connected with the connecting piece to downwards to peel off a cable skin; when the driving wheel 51 slides to the transition face 023 along the straight face 022, the end of the first chuck 02 which is acted by the torsion spring in the left and right knife rests 3 is reset under the action of the driving wheel 51, namely, the cable chuck 2 is opened, at the moment, the roller 6 is propped against the limiting step 122 in the shell 1, and the two handles cannot be continuously close to each other. When the force applied to the two handles is released, the two handles are all reset to the initial state, as shown in the state of figure 2.

The wire stripping device effectively solves the problem that the existing wire stripping device is easy to clamp and damage and has potential safety hazard. Through the arrangement of the connecting piece and the matching of the push rod which is rotatably arranged, when force is continuously applied to the two handles, the first chuck 02 is disengaged, the two chucks are far away from each other and are unfolded, and a cable or a finger or the like clamped in the middle of the cable chuck 2 is disengaged from the two chucks.

It is to be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are intended to be within the scope of the utility model.
