Embodiment 1

[0038] Such as Figure 1 to Figure 12 As shown, a conveniently adjustable electric wire bending pliers of the present invention includes needle-nose pliers, and the needle-nose pliers include two cross-hinged pliers 1, and the upper ends of the pliers 1 are respectively a left pliers head 11 and a right pliers head 12. The upper ends of the left pliers head 11 and the right pliers head 12 are in the shape of a truncated cone with a small upper part and a larger lower part. The lower end surface of the head 2 is provided with a first conical blind hole 21 matching the upper end of the left pliers head 11, the right end surface of the inverted L-shaped indenter 2 is provided with an arc-shaped gap 22, and the right pliers head 12 is provided with a rectangular block 3, The lower end surface of the rectangular block 3 is provided with a second frustum blind hole 31 matched with the upper end of the right pliers head 12, the upper part of the front end surface of the rectangular b...

Embodiment 2

[0048] Such as Figure 13 As shown, the only difference between this embodiment and the first embodiment is that the inner surface of the clamping block 41 is provided with an opening 43 matching the rectangular block 3 on the side close to the rack 4, and other structures are the same Same as Embodiment 1.

[0049] Such a structural design, when rotating the turntable 52 to drive the two clamping blocks 41 to move to the center, can make the inner side of the clamping block 41 directly above the rectangular block 3, thereby making the distance between the two clamping blocks 41 inner sides It is shorter and can bend wires with smaller angles.

Embodiment 3

[0051] Such as Figure 14 As shown, the only difference between the present embodiment and the second embodiment is that the free end of the rack 4 is provided with a stopper 44 near the side of the gear, and the stopper 44 is provided with a third thread near the end surface of the corresponding rack 4. hole, the rack 4 is provided with a third stepped hole 45 at the position corresponding to the third threaded hole, and a connecting bolt is arranged in the third stepped hole 45, except that, the rest of the structure is the same as that of the second embodiment.

Abstract

The invention belongs to the technical field of wire bending pliers, and in particular to a convenient-to-adjust wire bending pliers, which comprise a needle-nose pliers, an inverted L-shaped press head is sleeved on a left jaw, the lower end surface of the inverted L-shaped press head is provided with a first frustum blind hole which matches the upper end of the left jaw, the right end surface ofthe inverted L-shaped press head is provided with an arc-shaped gap, a rectangular block is sleeved on a right jaw, the lower end surface of the rectangular block is provided with a second frustum blind hole which matches the upper end of the right jaw, the upper portion of the front end surface of the rectangular block is provided with a rectangular hole, the right end surface of the rectangularblock is provided with a first stepped hole at a position corresponding to the rectangular hole, a clamping block is fixed at one end of each rack, one end, which is close to the inverted L-shaped press head, of the side of each clamping block is provided with a V-shaped notch, one end, which is far from the inverted L-shaped press head, of the side of each clamping block is provided with a rectangular notch which matches the other rack, and the right end of a first hexagonal prism passes through the first stepped hole and is connected to a rotary disk. The objective of the invention is to solve the problems of inconvenience in carrying and use and narrow application range caused by the structural defects of conventional tools for the secondary bending of wires.

Description

technical field [0001] The invention belongs to the technical field of electric wire bending pliers, and in particular relates to a conveniently adjustable electric wire bending pliers. Background technique [0002] With the increasing development of the power grid, new substation projects and substation comprehensive automation transformation projects are increasing. In electrical construction, secondary cable construction is one of the important construction projects, and its construction progress and quality are related to the progress and quality of the entire project. [0003] Nowadays, the number of secondary cables for protective screens or switch cabinets in substations is increasing. The workload and difficulty for construction personnel to use the traditional manual bending method for wiring are very large, and manual bending is random. There are differences in the bending arc, the wiring work efficiency is low, the process is not beautiful, and the construction q...
