Axis direction motion.When blade tooth 52 moves to it is inconsistent with steel cap 2 when, blade tooth 52 will apply at the steel cap 2 to insulator grabs
Holding force.Now, if blade tooth 52 is subjected to displacement, insulator will be driven to move therewith.
To ensure that blade tooth 52 has sufficiently large grasping force to insulator, the quantity of blade tooth 52 is at least three.The application
In, the quantity of blade tooth 52 is three, and three blade tooths 52 are uniformly arranged on rotation fixed ring 51.Certainly, art technology
Personnel can be according to the quantity for being actually needed adjustment blade tooth 52, such as 4,5 or 6 etc., and it belongs to the protection model of this area
Enclose.
In multiple blade tooths 52, including at least a main tooth 521, other blade tooths 52 are secondary tooth 522.In the application, if
A main tooth 521 is put, certainly, people in the art can adjust the quantity of main tooth 521, have no effect on making for insulator assembly and disassembly pawl
With with effect.In the application, main tooth 521 is applied not only to grasp insulator, is additionally operable to contradict with the locking pin of insulator 22.
When being rotatablely connected screw mandrel 41, locking pin 22 defines the rotation of grasping piece 5, so that connection wire rod 41 occurs with grasping piece 5
Relative motion.Illustrated here, conflict occurs with locking pin 22 to main tooth 521, the length of main tooth should meet：Insulator is assembled and disassembled
After pawl is connected with insulator, be rotatablely connected screw mandrel or rotation fixed ring, make blade tooth that relative motion occur with insulator, when blade tooth with
When insulator relative distance reaches maximum, main tooth can still contradict with locking pin.
Compared to main tooth 521, secondary tooth 522 has shorter length, its role is to grasp insulator, without with locking pin
22 is inconsistent.
With reference to the size of insulator steel cap 2, the span of the main length of tooth 521 is 5.0-6.0cm, the secondary length of tooth 522
Span is 3.5-4.5cm.In this example, the main length value of tooth 521 is 5.6cm, and the secondary length value of tooth 522 is 3.6cm.
