Detailed Description

In the description, numerous specific details are provided to provide a thorough understanding of embodiments of the utility model; however, it will be apparent to one skilled in the art that the present utility model may be practiced without one or more of these specific details; in other instances, well-known details are not shown or described in order to avoid obscuring the utility model.

The detailed description and technical content of the present utility model are described below with reference to the drawings, which are, however, provided for reference and illustration only and are not intended to limit the present utility model.

Referring to fig. 1 to 4, there are respectively a schematic exploded view of the support blade and the blade set in two lateral directions and a perspective view of the wire stripper 1 in two lateral directions. The utility model relates to a wire stripper 1 with a cutting support structure, which comprises a first clamp handle 10, a second clamp handle 20, a blade set 30, a spring 40 and a pair of support baffles 50. The first clamp handle 10 and the second clamp handle 20 are pivoted to each other. The blade set 30, the spring 40 and the pair of support tabs 50 are disposed between the first jaw 10 and the second jaw 20.

The second handle 20 is pivotally connected to the first handle 10 by a pivot 25. The first clamp 10 comprises a first clamp base 11. The second jaw 20 further includes a second jaw 22 disposed in correspondence with the first jaw 12.

The blade set 30 includes a first blade 31 and a second blade 32 disposed on opposite sides of the first jaw 10 and the second jaw 20, respectively. The first blade 31 and the second blade 32 are locked to the first grip 10 and the second grip 20 by a plurality of screws 35. Specifically, the blade set 30 is locked to the first jaw handle 10 and the second jaw handle 20 near the pivot 25. It should be noted that the screws 35 may be removed and replaced when the first blade 31 or the second blade 32 is worn.

In practice, the blade set 30 may be configured such that only the first blade 31 is disposed on the first jaw 10 and an anvil is disposed on the second jaw 20. Alternatively, the blade set 30 may be provided with a second blade 32 only on the second jaw shank 20 and a cutting board on the first jaw shank 10.

The two ends of the spring 40 are respectively fixed to the first clamp handle 10 and the second clamp handle 20.

Furthermore, the pair of support flaps 50 are disposed between the pivot shaft 25 and the blade set 30. The pair of support tabs 50 are each an arcuate sheet, preferably a metal sheet. The pair of support tabs 50 includes a first support tab 51 and a second support tab 52 respectively coupled to opposite sides of the first jaw handle 10 and the second jaw handle 20. In addition, the pair of supporting stoppers 50 are respectively disposed at one side of the blade set 30.

In this embodiment, one ends of the first support baffle 51 and the second support baffle 52 are coupled to the first handle 10 by a plurality of rivets 55, and the other ends extend to the second handle 20. The pair of support flaps 50 can provide a supporting force to the first and second handles 10 and 20 when the blade set 30 is cut.

Further, the pair of supporting blocks 50 can mainly provide supporting force for the first and second handles 10 and 20 when the blade set 30 is cut, so as to avoid displacement between the first and second handles 10 and 20 due to pushing by external force.

In an embodiment of the present utility model, the wire stripper 1 further includes a wire stripping structure 60. The wire stripping structure 60 is disposed at one end of the first jaw 11 and the second jaw 21. The wire stripping structure 60 includes a blade holder set 61 disposed on the first jaw 11 and a clamping holder set 62 disposed on the second jaw 21. The blade holder set 61 provides cutting operations, and includes a movable blade holder 611 and a fixed blade holder 612. The clamping set 62 provides clamping operation, and includes a movable clamping seat 621 and a fixed clamping seat 622. The stripper 1 can smoothly strip an insulation sheath of a cable under the combined force of the tool holder set 61 and the clamping seat set 62.

In one embodiment of the present utility model, the first clamp handle 10 further includes a first clamp sleeve 12; in addition, the second clamp handle 20 further includes a second clamp sleeve 22. The first sleeve 12 is sleeved outside the first clamp handle 10, and the second sleeve 22 is sleeved outside the second clamp handle 20. The first clamp sleeve 12 and the second clamp sleeve 22 provide a preferred gripping force.

It should be noted that the wire stripper 1 further includes a crimping structure 70. The press-connection structure 70 is disposed on two opposite sides of the first handle 10 and the second handle 20. More specifically, the press-fit structure 70 includes a plurality of concave cambered surfaces 71 and a plurality of convex portions 72 that are adjacent to each other. The concave cambered surfaces 71 and the convex portions 72 can be used for various crimping operations by a user, so that the convenience in use is improved.

Referring to fig. 5 to 7, a front view of the wire stripper of the present utility model when not in use, a plan view of the wire stripper when in use, and a cross-sectional view of the wire stripper at the support blade are shown. As shown in fig. 5, when the user does not apply force to the first clamp handle 10 and the second clamp handle 20, the spring 40 is not applied with an external force and is in a compressed state, and at this time, the first clamp handle 10 and the second clamp handle 20 are opened, and the blade set 30 is opened, so that a cable (not shown) can be inserted between the blade sets 30 to cut the cable.

As shown in fig. 6, when a user applies force to the first and second handles 10 and 20, the spring 40 is under an external force to be in a stretched state, and at this time, the first and second handles 10 and 20 are closed, and the blade set 30 cuts a cable passing between the blade sets 30.

As shown in fig. 7, it should be noted that the length of the pair of supporting tabs 50 extending to the second handle 20 is greater when the blade set 30 is closed than when the blade set 30 is opened, that is, the pair of supporting tabs 50 provides more supporting force to the second handle 21 when the blade set 30 is closed (cutting is performed), thereby preventing the first handle 10 and the second handle 20 from being displaced due to the pushing of the external force, so as to prevent the dislocation of the blade set 30 from being able to cut.

Referring to fig. 8, an exploded perspective view of another embodiment of the blade set of the wire stripper of the present utility model is shown. The present embodiment differs from the previous embodiment in the manner in which the support flaps 50 are arranged. In this embodiment, the pair of support tabs 50 includes a first support tab 51 coupled to the first jaw 10 and a second support tab 52 coupled to the second jaw 20.

In this embodiment, one end of the first supporting rib 51 is coupled to the first handle 10 by a plurality of rivets 55, and the other end extends to the second handle 20. In addition, one end of the second supporting rib 52 is coupled to the second jaw 20 by a plurality of rivets 55, and the other end extends to the first jaw 10. Accordingly, the first supporting baffle plate 51 and the second supporting baffle plate 52 are combined on opposite sides of the first clamp handle and the second clamp handle in a staggered manner, so as to provide balanced supporting force.

However, the above-mentioned embodiments are merely preferred embodiments of the present utility model, and the scope of the utility model is not limited thereto, i.e. the utility model is not limited thereto but is intended to be limited thereto. The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description. The present utility model is capable of other and further embodiments and its several details are capable of modification and variation in light of the present utility model, as will be apparent to those skilled in the art, without departing from the spirit and scope of the utility model as defined in the appended claims.
