Problems solved by technology

At present, most of the semi-conductive layer stripping tools are used. After stripping, the insulating layer is damaged to a certain extent, and the surface stripping lines are obvious, which needs to be re-polished. The price is relatively high, but the effect is not ideal. No damage, smooth surface, cheap cutting tools, widely used in the production of distribution network cables, but requires high strength control for production personnel

Abstract

The invention discloses a cutter capable of controlling the cutting depth. The cutter capable of controlling the cutting depth comprises a cutter handle (11), a fixed cutter support (9), a blade (7) and the like. The cutter is characterized in that the front end of the fixed cutter support (9) is provided with a cutting depth control device composed of a movable cutter support (4), a blade pressing plate (8), a blade fixing screw (5), a movable cutter support pressing plate (3), a movable cutter support fixing screw (1), a spring clamp (2) and the like, the movable cutter support (4) is provided with a movable cutter support moving groove (6), and the moving length L1 between the movable cutter support (4) and the fixed cutter support (9) is 1 mm to 5 mm larger than the tooth pitch L2 of a positioning tooth (13). The cutter is simple in structure, easy to machine, low in manufacturing cost, easy to popularize and easy to operate, an insulation layer is not damaged during cutting, the surface of the insulation layer is smooth, the electric field distribution state of a cable connector is improved, the service life of a cable is prolonged, and the cable accident rate is effectively decreased.

Description

[0001] Technical field: [0002] The invention relates to a cutting tool, in particular to a cutting depth-controllable cutting tool, which can be widely used in all fields requiring the cutting depth of cables, and is especially suitable for installing cable accessories for substation inspection and maintenance. [0003] Background technique: [0004] In the production process of cable terminals, the link that is most prone to quality problems is the stripping of the semiconductive layer. Often in the production process of this link, due to the uneven level of production personnel, the quality cannot be guaranteed, leaving a gap for cable terminals during production. defects in quality. Cutting depth requires a high degree of control for the production staff when using the tool. Cutting too shallow will make it difficult to peel off the semi-conductive layer. Cutting too deep will damage the electric field distribution of the cable, reduce the service life of the cable, and di...
