Handle and ballhead cause handle stock both ends not depart from from mounting hole.
As the further limits scheme of the utility model, spacing threaded hole is radially provided with quarter butt；Even
A rotary stopper notch is equipped with female connector cylinder and teeth sleeve；Branch sleeve and teeth sleeve are respectively sleeved at two quarter butts
On, and screwed by caging bolt by rotary stopper notch on spacing threaded hole, and one end protrusion of caging bolt
Outside spacing threaded hole.Enable to branch sleeve and teeth sleeve removable using the design of limit hole, caging bolt and notch
Unload formula and be installed on insulation axis both ends, be convenient for changing the branch sleeve and teeth sleeve of different model size；Simultaneously because switch
After dead point is crossed by mechanism, spring, which is released, mechanism can be made to continue to rotate under effect of inertia for operation, therefore sets rotary stopper notch
Large-scale idle stroke is provided, avoiding spring from releasing can be to the impact injury of operator's arm, the idle stroke of rotary stopper notch
Scope is 180 °.
As the further limits scheme of the utility model, anti-sliding rib is equipped with the outer circumferential walls of insulated handle.Using
Anti- sliding rib can play the role of anti-skidding during insulated handle use.
The beneficial effects of the utility model are：Teeth sleeve and collet head are installed using at the both ends of insulation axis, from
And realize the function of operating handle, moreover it is possible to form insulation system between handle stock, avoid Danger Electric shock risk, effectively enhance behaviour
Make the security of handle；Using insulated handle and ballhead handle stock both ends will not be departed from from mounting hole.
