Torque spring and synchronous mechanism can make two cams synchronous to closing up in the middle or separate to both sides.Usually cam is in torsion
Close up under the action of spring.When fixed cable is inserted into two cams of clamper, cam separates automatically, insertion
Power very little.Cam compressing cable surface generates frictional force after insertion, this frictional force can prevent cable from pulling out.It suitably chooses convex
The shape for taking turns material and cam curve, can achieve such mechanics effect --- and no matter external pull has much, is impossible to
Cable is pulled out from clamper.When dismantling cable, manually reversely exerts a force to cam, overcome spring torsion, synchronization mechanism handle
Cam is separated to both sides, and cable disengages with cam and deviates from automatically.
Obviously, the technical program has the following advantages:
(1) handling cable need not use the specific purpose tools such as spanner；
(2) charge and discharge operations are simple and fast laborsaving；
(3) pressing force is automatically generated by clamp structure, and pressing force is little under normal circumstances, pressure when cable is strongly pulled
