Specific embodiment
It is described in detail the utility model below with reference to the accompanying drawings.It should be noted that in the absence of conflict, this Shen
Please in embodiment and embodiment in feature can be combined with each other.
Referring to Fig. 1 to Fig. 3.
The utility model replacing spring of circuit breaker specific purpose tool, including mobile screw rod 3, upper internally threaded sleeve 1 and lower interior spiral shell
Line casing 2；The top of the mobile screw rod 3 has right-handed thread with left hand thread, lower part, and the upper internally threaded sleeve 1 has
There is the internal screw thread matched with the left hand thread on the top of the mobile screw rod 3 and is threaded in the upper of the mobile screw rod 3
Portion, the lower internally threaded sleeve 2 has the internal screw thread matched with the right-handed thread of the lower part of the mobile screw rod 3 and screw thread connects
It connects in the lower part of the mobile screw rod 3；Energy is equipped on the outer wall of the upper internally threaded sleeve 1 and the lower internally threaded sleeve 2
The fixation support claw being enough stuck on spring.
In use, first fixed support claw is stuck on spring, then clamps mobile screw rod with tool and gradually rotate, due to it is upper,
Lower internally threaded sleeve is fixed support claw and limits rotational freedom, and therefore, moving in rotation screw rod can make upper and lower internally threaded sleeve
Up and down side is mobile respectively, so that the spacing between upper and lower internally threaded sleeve expands, while fixed support claw is also located remotely from each other, i.e.,
Spring can be stuck to strut the spring of breaker, then detachable later and installation breaker spring.
In one embodiment, the fixed support claw includes that V-shaped pedestal 4 and two are separately fixed at the pedestal 4
Both ends the overhead kick pawl point 6 stretched out outwardly.Pedestal is used to support overhead kick pawl point, and overhead kick pawl point can fasten spring, make spring
