Abstract

The invention relates to a handle knife. The handle knife comprises a bottom plate and a vertical plate, wherein the vertical plate is welded at a rear part of the bottom plate, a split shaft is arranged on the vertical plate by a bearing, an upper vertical rod and a lower vertical rod are hinged with the split shaft, a pull spring is arranged between an upper part of the upper vertical rod and alower part of the lower vertical rod and is connected with the upper vertical rod and the lower vertical rod via hooks, a connection end is arranged at the bottom of the lower vertical rod, and an outer wiring end, an input wiring end and a ground wiring end are respectively arranged at a left side, a middle part and a right side of a front part of the bottom plate. The handle knife is simple in structure, the on / off of the circuit can be controlled by manual in a mode that operation is convenient, moreover, energization and breakage stability also can be ensured, and a circuit fault is effectively prevented.

Description

technical field [0001] The invention relates to a circuit control device, in particular to a switch knife with a handle. Background technique [0002] Switch knife, also known as isolating switch, is an electrical component mainly used to control circuit on and off. Generally, in relatively simple circuits, in order to save costs, only manual control handles are usually used. This method is simple and convenient, but the problem is that it is often difficult to accurately control the on-off switch of the circuit by manual operation. Control on-off points. Contents of the invention [0003] Now, in order to meet the above-mentioned requirement for accurate control of circuit on-off, the present invention proposes a handle switch knife. [0004] The technical problem to be solved by the present invention adopts the following technical solutions to realize: [0005] A handle switch knife, comprising a bottom plate and a vertical plate welded to the rear of the bottom plate...
