Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and implement
Example is described in further detail the utility model.It should be appreciated that specific embodiment described herein is only to explain this reality
With novel, it is not used to limit the utility model.
The short-circuit grounding wire that one kind of the utility model can temporarily lock out, as shown in Figure 1, including regular jaw 1, mobile pincers
Mouth 2, junction block 3, connecting tube 4, pull rod 5, hand lever 6, hook 7, elastic component 8 and handle 9, regular jaw 1, which is fixed at, to be connect
On line seat 3, the setting that moved jaw 2 slides is used for clamping line on junction block 3, through regular jaw 1 and the composition of moved jaw 2
The clip of head.One end of connecting tube 4 is fixed on junction block 3, and handle 9 is arranged in the other end, and pull rod 5 is arranged in connecting tube 4
It is interior, and can be moved in connecting tube 4, the both ends of pull rod 5 protrude from the both ends of connecting tube 4, one end and moved jaw 2
Hand lever 6 is arranged in connection, the other end；By pulling hand lever 6 to drive moved jaw 2 mobile, so that clip is opened.Elastic component 8
It is mounted on moved jaw 2, applies the thrust to regular jaw 1 to moved jaw 2 always, provide enough for clip by line
The clamping force of head clamping.Hook 7 is arranged on hand lever 6, and locking device 10 is arranged on handle 9.When in use,
Locking device is set on the handle；When locking, the locking device is closed, and hook 7 is locked in the locking dress
In setting, when unlocking, the locking device is opened, hook is separated with the locking device.Operator is in the item rationally having an effect
Under part, hand lever 6 is pulled, and then overcomes elastic component 8 to the thrust of moved jaw 2, locking device 10 is caught on by hook 7, is made
Clip remains opening state, and then clip is placed on designated position by operator, opens locking device 10, so that hook 7
It is separated with locking device 10, moved jaw 2 is mobile to regular jaw 1 by the thrust of elastic component 8, and then the end of a thread is clamped.
Specifically, as shown in Figure 1-3, locking device 10 includes reinforcing rod 101, bolt 102 and lever 103, reinforcing rod 101
It is fixed at the inside of 9 side of handle, 101 inside of reinforcing rod is axial to be arranged perforative guide hole 104, what bolt 102 slided
It is arranged in guide hole 104, lever 103 is rotatably provided on handle 9, and one end is flexibly connected with bolt 102, utilizes lever
103 driving bolts 102 are mobile.One end of rigid lever 103 is pushed out, the other end pushes bolt 102 mobile, so that the one of bolt
Distal process is for reinforcing rod 101, so that hook 7 is locked in the protrusion of bolt 102；When moved jaw 2 unlocks, pressing
One end of lever 103, tilts the other end, and then it is certain into reinforcing rod 101 to push bolt 102, and then makes bolt 102 and hang
Hook 7 separates.But in actual operation, due to the opening of regular jaw 1 and moved jaw 2 at side, use according to practical feelings
The direction of condition meeting earth wire is changed, and is unfavorable for the operation of operator.Therefore, two, and phase is arranged in locking device 10
To setting, enables operator to carry out selection according to actual direction and use one of locking device 10, can also make simultaneously
With two locking devices 10.Preferably, in order to increase the service life of bolt 102, and lock timed hook 7 and bolt are improved
Stability and reliability when 102 locking open up bolt on the reinforcing rod 101 of another opposite locking device 10 of bolt 102
Hole 105.
In one embodiment, elastic component 8 can be spring.Spring pops up in use in order to prevent, and spring pocket is mounted in
On pull rod 5.When in use, pull rod 5 is equivalent to the guiding bar of spring, keeps spring power output more stable.
In order to further increase the service life of ground line, and guarantee stability when clamping, regular jaw 1 and wiring
Seat 3 is wholely set, and be in U-shape structure.
In one embodiment, what the both ends of hand lever 6 were slided is connected on the two sides of handle 9.It can be moved pulling
Guiding role is played when jaw 2.In one embodiment, lantern ring 61 is arranged in the both ends of hand lever 6, and lantern ring 61 is sleeved on handle 9
On two sides, so that hand lever 6 has certain freedom degree when moving, it is effectively prevent 6 angle offset of hand lever in drawing process,
It causes hand lever 6 stuck, can not continue to move to.
In one embodiment, bolt 102 and 104 clearance fit of guide hole, it is contemplated that repeatedly after locking, bolt 102 may
There is micro deformation, if bolt 102 and 104 perfect matching of guide hole, are unfavorable for the long-time service of bolt 102.It can think
It arrives, pin hole 105 and bolt 102 are also clearance fit.
When the utility model is used, as shown in Figure 1-3, operator rationally have an effect under conditions of, pull hand lever 6,
And then overcome elastic component 8 to the thrust of moved jaw 2, make bolt 102 protrude from reinforcing rod 101 by lever 103, and insert
Enter in pin hole 105, hook 7 catches on bolt 102, and moved jaw 2 is carried out temporary locking.Wire clamp is placed on designated position
Afterwards, push bolt 102 to move into reinforcing rod 101 by presses lever 103 so that hook 7 is separated with bolt 102, at this time by
To the restoring force of elastic component 8, moved jaw 2 is mobile to 1 direction of regular jaw, and then the end of a thread is clamped.
The above is only the preferred embodiments of the utility model, are not used to limit the scope of the utility model；If
The spirit and scope for not departing from the utility model, are modified or replaced equivalently the utility model, should all cover in this reality
In novel scope of protection of the claims.
