Fig. 2 is the side structure schematic view of one embodiment of the invention.
Fig. 3 is the overlooking structure diagram of one embodiment of the invention.
The label of each component in attached drawing are as follows: internally threaded sleeve, 2 lower internally threaded sleeves, 3 mobile screw rods, 4 pedestals, 5 limits on 1
Position block, 6 overhead kick pawl points, 7 boss, 8 middle part shoulder blocks.
Specific embodiment
It is next below with reference to the accompanying drawings that the present invention will be described in detail.It should be noted that in the absence of conflict, in the application
Embodiment and embodiment in feature can be combined with each other.
Referring to Fig. 1 to Fig. 3.
Replacing spring of circuit breaker specific purpose tool of the present invention, including mobile screw rod 3, upper internally threaded sleeve 1 and lower inner screw sheath
Pipe 2；The top of the mobile screw rod 3 with left hand thread, lower part have right-handed thread, the upper internally threaded sleeve 1 have with
Internal screw thread that the left hand thread on the top of the mobile screw rod 3 matches and the top for being threaded in the mobile screw rod 3, institute
Stating 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 is threaded in
The lower part of the mobile screw rod 3；Being equipped on the outer wall of the upper internally threaded sleeve 1 and the lower internally threaded sleeve 2 can block
Fixation support claw 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
It does not shift, dystopy, designs in this way, fixed support claw may be implemented and be firmly stuck on spring, securely and reliably.
In one embodiment, the middle part of the mobile screw rod 3 is equipped with the middle part shoulder block 8 of on-circular cross-section.Middle part shoulder block is used for
The clamping of the tools such as spanner, is rotated convenient for clamping mobile screw rod, is easy force；Preferably, the middle part shoulder block 8 is in hexagonal prisms
Shape is simultaneously coaxially arranged with the mobile screw rod 3, designs in this way, the tools such as spanner suitable for existing most of type, practicability
More preferably.
In one embodiment, the maximum gauge of the middle part shoulder block 8 is greater than the outside diameter of thread of the mobile screw rod 3.This
Sample design, torque is larger, convenient for force.
In one embodiment, at least one end face of the mobile screw rod 3 is equipped with the boss 7 of on-circular cross-section.Boss is used
It in being caught in box spanner, is rotated convenient for clamping mobile screw rod, is easy force；Preferably, the boss 7 in hexagon simultaneously
It is coaxially arranged with the mobile screw rod 3, it designs in this way, suitable for six rib sleeves and box spanner in existing most of type,
Practicability is more preferable.
In one embodiment, the maximum gauge of the boss 7 is less than the outside diameter of thread of the mobile screw rod 3.It sets in this way
Meter is easy molding installation.
In specific implementation, nut-welding is can be used directly in corresponding position system in the middle part shoulder block 8 and the boss 7
At easy production.
In one embodiment, the inner wall of the upper internally threaded sleeve 1 and/or the lower internally threaded sleeve 2 is equipped with and is used for
The limited block 5 that the mobile screw rod 3 is limited.Limited block can guarantee that mobile screw rod in the activity in range that limits, is prevented
Only overexertion damages screw thread silk tooth.
In one embodiment, it is on-circular cross-section that the middle part of the mobile screw rod 3, which has one section of cross section,.It designs in this way,
It spanner etc. can be used securely clamps mobile lead screw and rotated.
In specific implementation, service personnel voluntarily can neatly select the proper implements such as spanner, sleeve revolve boss or
Middle part shoulder block makes upper and lower internally threaded sleeve distinguish up and down side mobile, so that set tube spacing expands, while fixed support claw is along straight
Line movement, the spring of breaker is strutted, to be disassembled and installed.
