One end of the handle rod is installed with a handle head, and the other end is installed with a handle grip. The handle rod is composed of a handle assisting rod, a connecting piece and an extension connecting rod. One end of the handle assisting rod and the extension connecting rod are respectively connected by the connecting piece, and the handle rod and the extension connecting rod after connection are perpendicular to each other, forming a handle rod with an overall L-shaped structure. A handle grip and a handle head are respectively installed at the other ends of the handle assisting rod and the extension connecting rod. The extension connecting rod is used to extend the operation length space of the handle, and the handle assisting rod is used to reduce the force applied during the handle operation. On the end face of the handle head away from the handle assisting rod, a plug adapted to the operation interface of the 10kV switch cabinet circuit breaker is provided for convenient operation.

[0006] Preferably: The connecting piece is a cylindrical connecting seat. A first installation groove and a second installation groove are respectively provided on the bottom surface and the side surface of the cylindrical connecting seat. The extension connecting rod and the handle assisting rod are respectively inserted and installed in the first installation groove and the second installation groove, and are installed by means of threaded connection or bolt fixation, which is convenient for the overall installation and disassembly.

[0007] Preferably: A handle grip is detachably installed on the outside of the end of the handle assisting rod. The handle grip partially wraps the handle assisting rod. Uniformly arranged convex points or knurling are provided on the outer side surface of the handle grip to improve the friction force of the operator's hand holding the grip.

[0008] Preferably, the handle assist rod and the extension link are made of metal, and the handle grip is made of rubber to ensure safety during use.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] The 10KV switchgear circuit breaker maintenance operation handle designed by the present utility model removes the original handle grip part and only leaves the handle head, and installs an extension rod compatible with ordinary socket tools on the handle head to extend the operation length space of the handle. Various tools equipped in the socket tool can be used to operate the circuit breaker trolley to be inserted and removed without restriction. The handle assist rod is used to reduce the force applied during handle operation. The operation handle of the present utility model can also cooperate with an electric wrench for faster operation, saving precious maintenance time, enabling faster completion of maintenance power transmission, and reducing power outage time.
