Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] like figure 1 , 2 . As shown in 3, an operating lever that can rotate the fuse assembly of a fuse is characterized in that it includes a handle 1 and a working head 2 installed on the handle, the handle is an insulating rod, and the working Below the head is a section of circular tube 3 on which a clip 4 is installed. The clip is a round hoop, and the inner side of the hoop has two fan-shaped baffles 5 arranged at intervals. Between the two fan-shaped baffles is a fan-shaped The vacancy 6, the arc length of the sector-shaped baffle is shorter than the arc length of the sector-shaped vacancy.

[0020] When the joystick is used, it is required that the fuse assembly of the circuit breaker to be loaded and unloaded has a structure that holds the fan-shaped block of the joystick, that is, there are two assembly blocks set at intervals under the fuse assembly tube ...

Abstract

The invention relates to the technical field of electrical engineering, in particular to an operating rod capable of rotatably assembling and disassembling a fuse assembly of a fuse protector. The operating rod is characterized in that the operating rod comprises a handle and a working head mounted on the handle; the handle is an insulating rod; a section of circular pipe is arranged below the working head; a clamping piece is mounted above the circular pipe and is a circular hoop; two fan-shaped blocking pieces are arranged on the inner side of the circular hoop in a spaced mode; a fan-shapedvacant part is formed between the two fan-shaped blocking pieces, and the arc lengths of the fan-shaped blocking pieces are smaller than the arc length of the fan-shaped vacant part; limiting pieceswith the side faces each in a table shape and made of plastic are arranged in the circular pipe; and table-shaped cavities are formed in the limiting pieces, and openings of the cavities are formed towards the circular hoop. The operating rod can assemble and disassemble the breaker fuse assembly, and has the advantages of being simple, convenient and safe.

Description

technical field [0001] The invention relates to the field of electric technology, in particular to an electric operating lever. Background technique [0002] The circuit breaker includes a housing and a fuse assembly inside the housing. The fuse assembly further includes a fuse assembly tube and a fuse in the fuse assembly tube. When in use, the fuse in the fuse assembly tube When the fuse is blown, the entire fuse assembly must be replaced. Because the circuit breaker is generally installed at a higher position, there is no tool for replacing the fuse assembly of the circuit breaker in the prior art, and electricians need to climb up to operate, which has the disadvantages of troublesome operation and unsafety. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned shortcomings, and provide a simple, convenient and safe operation lever for loading and unloading the fuse assembly of the circuit breaker. [0004] The technic...
