Hold casing to turn to the inside, lockable mechanism is in lockup state at this time.When we press the rear end of poke rod, you can pass through pressure
Bar moves down bar, and grip sleeve can turn to the inside, and lockable mechanism is in the unlocked state at this time.
When clamping jaw is in open configuration, the sliding pin in left side is located at the rear end of regulating tank, since the drive rod in left side is grown
Degree is more than the driving pole length on right side, and therefore, the angle that left side clamping jaw is opened laterally is less than what right side clamping jaw was opened laterally
Angle.Particularly, we can by the torsional spring on clamping jaw at left and right sides of reasonable design and position the pretension elastic force of disc spring with
And the parameter such as coefficient of elasticity so that when needing to clamp electrical body, actuating sleeve can be first moved forward, is then rotated further by actuating sleeve, from
And by connection unit promote drive rod move forward, at this time left side drive rod make left side clamping jaw in grip sleeve inwardly
Rotate, and then keep opposite due to the larger pretension elastic force of positioning disc spring between left side grip sleeve and the flexible core bar of inside
It is fixed.At the same time, right side drive rod makes the flexible core bar on right side first stretch out grip sleeve, and the grip sleeve on right side is then due to turning round
The larger pretension elastic force remains stationary of spring.When we continue to move forward actuating sleeve, the grip sleeve in left side turns to the inside in place,
And be locked out mechanism and be locked at connection status, then its internal flexible core bar overcomes the elastic force of positioning disc spring and forward extends out,
The hook of telescopic core boom end is moved into place in advance.At the same time, the flexible core bar inside the grip sleeve on right side forward extends out
In place, then, grip sleeve overcomes the elastic force of torsional spring together with internal flexible core bar and turns to the inside in place, and is locked out machine
Structure is locked at connection status.The hook of right side telescopic core boom end convex is overlapped on the hook of left side clamping jaw, so as to fulfill a left side
Connection between the flexible core bar in the right side.Then actuating sleeve is rotated backward, so that drive drive rod to be moved rearwards by connection unit, it is right
The drive rod of side forms a pulling force to telescopic core bar, so that left and right is stretched, tightly hooking is together for the hook of core bar.This
Outside, which forms the telescopic core bar on right side one moment of torsion, and flexible core bar turns to the inside by center of rotation of hook, after
And drive the grip sleeve on right side to turn to the inside, in the rear side retraction grip sleeve for the core bar that stretches at this time.And left side is flexible
Sliding pin on core bar first slides on drive rod in regulating tank, and therefore, drive rod does not work the clamping jaw in left side, that is,
Say, the drive rod in left side has a bit of idle stroke.Deng left side flexible core bar on sliding pin against on the drive rod in left side
When adjusting front of the slot, the drive rod in left side forms telescopic core bar one pulling force, which forms one to the telescopic core bar in left side
A moment of torsion, flexible core bar turn to the inside by center of rotation of hook, then drive the grip sleeve in left side to turn to the inside,
Stretch at this time in the rear side retraction grip sleeve of core bar.The grip sleeve that the left and right sides turns to the inside can be formed electrical body
Reliable clamping.
When we need to discharge electrical body, actuating sleeve can be rotated forward again, is driven so as to be promoted by connection unit
Bar moves forward.Right side drive rod promotes the flexible core bar on right side to move forward immediately at this time, the hook of its end and left side
The hook of telescopic core boom end disengages, and the drive rod in left side has an idle stroke due to the presence of regulating tank so that left side
Flexible core bar will not forward extend out, at this time the left and right sides grip sleeve be then turned out at the same time under the action of torsional spring；So
After be moved rearwards actuating sleeve, claw can laterally rotate opening automatically under the action of torsional spring at this time, so as to discharge electrical body.
Finally, as shown in figure 8, we can also have in the outer sheath of grip sleeve it is flexible made of silicon rubber
