(4) setting of spring can make the first clamp and the second clamp be restored to the free state of spring, when spring is
When the first clamp of free state and the second clamp are acute angle, spring elongation deforms when compressing snap ring, after snap ring compresses, bullet
Spring is restored to free state, when spring be the first clamp of free state and parallel the second clamp when, need first compressed spring to
So that after the first clamp and the second clamp are at an acute angle, swivel nut, snap ring, conductor are placed into mounting groove, reduce compression in this way
The power that snap ring needs.Since clamp have certain thickness, the setting of spring stack that spring can be made to be shunk on the direction of horizontal plane.
(5) setting of bottom tub can reduce the contact between clamp and pedestal, reduce friction.
(6) setting of bulge loop can block swivel nut in madial wall, prevent swivel nut from being moved in mounting groove.
(7) setting of conductor slot is the length for preventing the length of conductor to be more than swivel nut, and after installing to swivel nut, conductor is located at
Outside swivel nut.
(8) since the first clamp and the second clamp need certain rigidity, so certain thickness is needed, but snap ring
Thickness value it is smaller when, cut down slot setting can prevent clamp thickness be more than snap ring thickness.
(9) setting of cylindrical handle increases the contact area of hand and equipment, and the setting of Anti-slip cover can increase hand and set
Standby frictional force.
