Description

Technical Field

[0001] The utility model relates to the technical field of cable stripping, in particular to a small cable stripping knife. Background Art

[0002] As a key carrier for power and signal transmission, cables play an irreplaceable role in every field of modern society. From lighting and household appliances in daily life to the operation of large-scale machinery in industrial production, from data signal transmission in the communications field to control systems in transportation, cables are everywhere.

[0003] When reliable connections between cables, between cables and various electrical devices, or when a cable fault occurs, the cable sheath must be peeled back to expose the internal conductors. Connectors, such as wiring terminals and bolts, ensure close contact between the conductors to ensure smooth current or signal transmission. Currently, cable sheathing is performed using a utility knife or specialized tools.

[0004] However, during the stripping process of current cable stripping tools, workers need to exert force, which is difficult to control and the cutter may slip. Excessive slippage can easily cause injury to others or themselves, posing a major safety hazard. Utility Model Content

[0005] The purpose of the utility model is to provide a small cable stripping knife to solve the problem that the current cable stripping tools are easy to cause injuries to others and oneself and have great potential safety hazards.

[0006] To achieve the above-mentioned purpose, the basic solution provided by the utility model is: a small cable stripping knife, comprising a handle, a blade detachably connected to the handle, a through hole formed on the blade, a safety ring sleeved on the through hole, and clamping components for clamping the cable are respectively provided on both sides of the safety ring.

[0007] The working principle of the utility model is as follows: a small cable stripping knife, when it is necessary to strip the cable, first hold the knife handle with your hand, gently apply force to remove the safety ring from the raised end of the knife handle to separate it from the knife handle, then continue to pull the safety ring to rotate and unfold the safety ring around the hinge point, after opening the blade, put the safety ring on the cable to be stripped, and after confirming that the cutting position of the blade is appropriate, start the cable stripping operation; when the cable stripping work is completed, first take out the safety ring sleeved on the cable, then fold the blade into the storage groove of the knife handle, and re-hook the safety ring on the raised end of the knife handle to ensure the safety of the tool during carrying.

[0008] The beneficial effects of the present invention are as follows: the safety ring is sleeved on the through hole of the blade. During the peeling operation, when the tool accidentally slips, the safety ring can play a limiting role, greatly reducing the risk of the tool directly scratching the skin and causing serious injury. Moreover, when the blade is folded, the safety ring can also be hooked on the raised end of the tail of the handle to play the role of a safety lock, which can prevent the blade from accidentally slipping out. At the same time, by fine-tuning the clamping assembly, the splint can be made to fit the surface of the small cable more closely, thereby playing a stabilizing role.

[0009] Option 2 is the preferred option of the basic option. The clamping assembly includes a screw, a threaded hole is provided on the safety ring, the screw is threadedly connected to the threaded hole, a splint is provided at one end of the screw, and a plurality of steel balls are rotatably connected to the splint; through the cooperation of the splint, the screw and the steel balls, the screw is fine-tuned to make the splint fit the surface of the cable.

[0010] Option three is a preferred option of the basic option. The knife handle is hinged to the blade, and a storage slot is provided on the knife handle. By hingedly connecting the knife handle to the blade and providing the storage slot, the blade can be folded and stored in the storage slot of the knife handle, which is convenient for carrying and storage.

[0011] Option 4 is the preferred option of the basic option. The tip of the blade is arc-shaped. Setting the tip of the blade into an arc shape facilitates better fitting the curvature of the cable surface during the cable stripping operation, is more conducive to cutting on the cable sheath, and improves the quality and efficiency of stripping.

[0012] Option 5 is the preferred option of the basic option. The knife handle is provided with anti-slip grooves. The anti-slip grooves on the knife handle increase the friction between the hand and the knife handle, effectively preventing the worker's hand from slipping on the knife handle when performing cable stripping operations.

[0013] Option six, which is the preferred option of the basic option, is provided with a hook and a hanging rope on the knife handle; the hook and the hanging rope are provided on the knife handle to facilitate hanging the skinning knife on the wrist, tool belt or other fixed position.

[0014] Option seven is a preferred option of option two, in which a grip wheel is provided on the screw rod; the grip wheel is provided on the screw rod to facilitate the rotation of the screw rod. BRIEF DESCRIPTION OF THE DRAWINGS
