Problems solved by technology
However, the handle cover that distinguishes the long hole and the short hole by making small marks is easy to be overlooked just like the long and short holes in the product itself. It can only be prevented by visual inspection before assembly, and the problem of installing the wrong handle cover will still occur.
This in turn also leads to assembly of the wrong type of attachment
And the inspection of the inspection tool is only the inspection after assembly, and the problems cannot be found in time before and during assembly.

Embodiment Construction
[0033] In order to have a clearer understanding of the technical features, purposes and effects of the invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings, in which the same reference numerals represent the same parts.
[0034] Such as figure 1 As shown, the present invention provides a handle 10. The handle 10 has a body 12 and an operating portion protruding from the body 12. There is a shaft hole 122 on the body 12, and the handle 10 can be pivoted through the shaft hole 122. It is arranged on a switchgear, and the operating part 14 extends along the axial direction of the body 12, and the opening and closing of the switchgear can be controlled by toggling the operating part 14.
[0035] It should be noted that, in this embodiment, a protrusion 142 is protruded from the operating portion 14 .
[0036] After the original handle cover with a long hole and the handle cover with a short hole ...

The invention relates to a hand shank. The hand shank (10) is provided with a main body (12) which can be arranged on switch equipment in a shaft manner and an operating part (14) arranged on the mainbody (12) in a protruded manner, wherein the operating part (14) extends along the axial direction of the main body (12), and a bump (142) is arranged on the operating part (14) in a protruded manner. Such a scheme is simple in structure and easy to implement, and thus a hand shank sleeve (a hand shank sleeve with a long hole) can be uniformly used for cooperating correspondingly, and the installation process is greatly simplified.
Description
[0001] This case is a divisional application based on the parent application filed on August 22, 2012, the application number is 201210301921.2, and the invention name is "handle and circuit breaker, multi-stage circuit breaker and circuit breaker with accessories". technical field [0002] The invention relates to a handle, a circuit breaker using the handle, a multi-stage circuit breaker and a circuit breaker with accessories, in particular, a handle that can be used with a handle cover, and a circuit breaker, a multi-stage circuit breaker using the handle Circuit breakers and circuit breakers with accessories. Background technique [0003] The handle of the multi-stage circuit breaker needs a handle cover to connect the handles of all levels, so that the product can be better combined into a whole. At the same time, multi-level products will be assembled with different types of accessories, and the protruding ends of the accessories will also be inserted into the handle c...
