Abstract

The utility model relates to an electrician blade. An original electrician knife whose knife tip is easy to slip from the cable sheath can hurt the hands of the staff at the time of stripping the cable sheath. The blade shape of the utility model in formed by the connection between a section of convex circular arc line and a section of concave circular arc line. The convex part is used for longitudinally cutting the cable sheath in a pressing way, and the concave part is used for cutting the cable sheath in a loop way. thus the cable sheath can be quickly effectively and conveniently stripped.

Description

Electrotechnic blade

The utility model relates to a kind of Electrotechnic blade that cuts cable sheath.

Cable needs the crust of its termination is cut off in use, connects with the metallic cable that exposes wherein.When carrying out this operation, instrument commonly used is an electrician's knife, earlier with electrician's point of a knife along vertically one section of cutting of cable socket, and then cut a circle around cable, the crust of cable socket is cut away.

Existing electrician's knife is very bad usefulness when carrying out this operation, because the distance of point width handle of a knife is far away, the distance of centre of gravity cable of handle of a knife is far away during use, and therefore very easily slippage damages staff's hand.

The purpose of this utility model provides a kind of novel Electrotechnic blade that is used for cable peeling, and it can peel cable sheath convenient, quickly and easily with special blade shapes.

The utility model is achieved in that

It has a knife back (1), and the front of the knife back (1) is combined with blade (2), and the cutting edge shape of blade (2) is to be formed by the circular arc line (3) of one section protrusion and one section recessed circular arc line (4) handing-over together.On the knife back, can load onto handguard (5).Also can load onto handle of a knife (7) on the knife back, can be equipped with on the handle of a knife (7) and can fold into the cutter that folds, saw and screwdriver.

During with this Electrotechnic blade strip cable crust, can the one hand-held knife back (1), with recessed circular arc line knife edge part around first circle of the cut cable of desiring to cut away and incision, then with circular arc line (3) knife edge part that protrudes along cable socket vertically by cutting post-tensioning, cable sheath is vertically cutd open also, thereby finish the operation of strip cable crust.

The utility model has the advantages that and rapidly, effectively, also to peel cable sheath at an easy rate, be difficult for staff is damaged, improved operating efficiency.
