Description

A cable stripping knife saw

technical field

The utility model relates to a hand tool, in particular to a cable stripping tool used for stripping the insulation layer of cables.

Background technique

Electric maintenance personnel need to use a utility knife and a saw to strip the cable armor and insulation layer when making the cable head. This traditional method has the problems of difficult stripping and low work efficiency, especially when the cable is stripped in a narrow working space. The work is more difficult.

Utility model content

The purpose of the utility model is to provide a cable stripping saw with convenient and safe operation and high working efficiency.

The purpose of this new model is achieved in this way: a cable stripping knife saw, the lower part of the positioning bracket is fixed on the front part of the handle, the upper part of the positioning bracket is arc-shaped, and a shaft is installed on the upper part of the arc-shaped positioning bracket, which can be rotated The ground is equipped with a pulley, and the saw blade is placed in the opening slot at the front of the handle. The blade and the teeth of the saw blade protrude upwards and downwards from the handle respectively, and the fastening bolt passes through the holes on the handle and the saw blade. Secure the knife saw blade to the handle.

The cross-section of the front part of the handle is oval, and the lower part of the positioning bracket is oval similar to the front part of the handle.

The holes on the above-mentioned knife and saw blades are strip holes.

The rear portion of the handle is provided with a non-slip sleeve.

Compared with the prior art, the utility model has the following characteristics:

1. Easy to operate and ensure safety: in order to ensure safety, a pulley is set in the positioning bracket to avoid the operator slipping and hurting the operator when peeling the cable, ensuring the quality of cable stripping, improving work efficiency and saving time .

2. Adapt to cable stripping of different specifications: the height of the blade of the saw blade can be adjusted in a small range through the position of the bolt on the strip hole, so that the distance between the blade of the saw blade and the pulley can be adjusted. To meet the stripping height requirements of cables of different diameters.

The utility model has the characteristics of small and exquisite appearance, easy to carry, easy to manufacture and low cost.
