[0002] It is well known that the isolation knife (commonly known as "knife gap") is the most used electrical appliance in electrical appliances, and its working principle and structure are relatively simple. The isolation knife can open the circuit, interrupt the current or make it flow to other electronic components of the circuit. The most common isolation knife is a mechanical and electrical device operated by people, which has one or several electronic contacts. The "closed" of the contact indicates that the electronic contact is conductive, allowing the current to flow; the "open" of the switch indicates that the electronic contact is not conductive to form an open circuit, which does not allow the current to flow.
[0003] However, the isolation knife used in the market at present, because the manufacturers reduce the cost as the purpose, makes the isolation knife to appear the bending of a certain degree under the long time high strength use, leads to unable normal use. SUMMARY
[0004] The utility model discloses a kind of isolation knives, to solve the isolation knife used in the market mentioned in above background art, because manufacturers reduce the cost as the purpose, makes the isolation knife to appear the bending of a certain degree under the long time high strength use, leads to unable normal use.

[0006] Preferably, the surface of the isolation knife main part is equipped with notch in adjusting hole side, and the notch is connected with adjusting hole.
[0007] Preferably, the surface bottom of the isolation knife main part is fixedly connected with contact block in notch two sides.
[0008] Preferably, the surface of the isolation knife main part is equipped with guide circle in recess notch and reinforcing rib surface.
[0009] Preferably, the isolation knife main part and reinforcing rib adopt integral cold-pressing structure design.
[0010] Beneficial effects
[0011] Compared with prior art, the utility model has the beneficial effects that:
[0012] In combination with the structural design of the utility model, the reinforcing rib is additionally arranged on the surface of the isolation knife main body, so that the isolation knife is not easy to bend under high strength use, the service life is improved, and meanwhile the reinforcing rib and the isolation knife main body are integrally cold-pressed, the strength is effectively improved, and thus the problems in the background art are solved.
