Detailed Description

As shown in fig. 1 to 6, a preferred embodiment of the cable stripping tool for a construction site includes at least two electrician knives, the electrician knives are disposed on a movable wire clamp, the movable wire clamp is provided with at least two mounting holes, the mounting holes are used for mounting the electrician knives, and the electrician knives include movable blades; the movable wire clamping hoop comprises a first arc-shaped hoop 1 and a second arc-shaped hoop 2, one end of the first arc-shaped hoop 1 is hinged to one end of the second arc-shaped hoop 2, and the other end of the first arc-shaped hoop 1 is detachably connected with the other end of the second arc-shaped hoop 2 through a connecting piece 3.

This technical scheme installs electrician's sword on movable wire clamp, movable wire clamp is used for binding round on the cable, when sliding or rotating electrician's sword, the cutter can be avoided coming off to movable wire clamp, and the size of movable wire clamp and cable diameter phase-match (behind first arc hoop 1 and the locking of second arc hoop 2, the inner circle size of movable wire clamp slightly is greater than needs cutting cable diameter), after the blade is adjusted to certain length, the electrician's sword of operating again skins the cable, the process of skinning is not only safer, and the cutting process is more stable. In addition, the cutting depth of the blade is constant, and the core wire cannot be damaged due to human misoperation.

Further, the electrical knife includes an electrical knife for circular cutting 4 and an electrical knife for axial cutting 5, the electrical knife for circular cutting 4 is provided with a movable blade for circular cutting 41, and the electrical knife for axial cutting 5 is provided with a movable blade for axial cutting 51. The electrical knife 4 for circular cutting is used for cutting the cable sheath in an annular mode, the electrical knife 5 for axial cutting is used for scratching the cable sheath in an axial direction, and the general wire stripping operation is as follows: firstly, axial cutting is carried out, and then annular cutting is carried out.

Further, a connecting sleeve 6 is arranged at the mounting hole; the electrical knife 4 for circular cutting is mounted on the connecting sleeve 6 of the first arcuate clamp 1, and the electrical knife 5 for axial cutting is mounted on the connecting sleeve 6 of the second arcuate clamp 2. The electrician knife can be inserted and connected with the mounting hole, and the connecting sleeve 6 can be fixed by a locking screw or by glue.

Furthermore, the electrician knife adopts a knife with a telescopic blade, and the blade telescopic mechanism can adopt a knob or a direct pushing type. The specific structure disclosed in this embodiment is:

the circular cutting electrical knife 4 comprises a shell 42, a circular cutting blade 41 is inserted into the shell 42, a strip-shaped opening 43 is formed in the circular cutting blade 41, a rack 44 is arranged on the strip-shaped opening 43, the rack 44 is meshed with a gear 45, the gear 45 is coaxially connected with a knob 46, and the knob 46 is rotatably arranged on the shell 42. The rotation of knob 46 is equipped with certain resistance, because the size of knob 46 is far greater than the size of gear 45, therefore it is laborsaving process when rotatory knob 46 drives the blade and removes, on the contrary, after the length adjustment of blade finishes, the blade slides from top to bottom if drive gear 45 rotates, need overcome great resistance, and electrician's sword receives vertical power less in the cutting process, and the blade is difficult for reciprocating. Alternatively, the transmission of the blade can adopt other structures, such as a direct-push type belt knife structure with a limit position or a knife with a worm gear structure.

The structure of the electric knife for circular cutting 4 is the same as that of the electric knife for axial cutting 5, and the installation angle of the electric knife for circular cutting 4 is ninety degrees different from that of the electric knife for axial cutting 5.

Further, in this embodiment, the connecting member 3 includes a rotating rod 31 hinged to the end of the second arc-shaped hoop 2, the rotating rod 31 is in threaded connection with a butterfly nut 32, the butterfly nut 32 is configured to cooperate with a U-shaped slot, and the U-shaped slot is disposed at the end of the first arc-shaped hoop 1.

In this embodiment, the movable wire clamp with one size corresponds to a cable with one diameter, in order to further improve the applicability of the tool, the movable wire clamp and the electrical knife can be designed to be detachable, and the electrical knife 4 for circular cutting and the blade 41 for circular cutting are simultaneously provided with the movable wire clamps with various models.

The using process is as follows:

step one, as shown in fig. 4, loosening the butterfly nut 32, separating the first arc-shaped hoop 1 and the second arc-shaped hoop 2, and clamping the movable wire clamping hoop from the side of the power cable;

step two, the butterfly nut 32 is locked, the movable wire clamping hoop is sleeved on the power cable 7, as shown in fig. 5, the knob of the electrical knife 5 for axial cutting is rotated, the blade 51 for axial cutting is extended out, the extending length of the blade 51 for axial cutting is judged according to the thickness of the cable sheath and the operation experience, and then the cable sheath is axially scratched.

And step three, as shown in fig. 6, performing annular cutting on the cable sheath by using an electrical knife 4 for annular cutting to finish the peeling operation.

The above-mentioned embodiments are merely preferred embodiments of the present invention, and should not be considered as limitations of the present invention, and the protection scope of the present invention should be defined by the technical solutions described in the claims, and includes equivalent alternatives of technical features in the technical solutions described in the claims. Namely, equivalent alterations and modifications within the scope of the invention are also within the scope of the invention.
