Block, two-phase is abutted against between contact block formed with stopper slot, by turning the conflict block being provided with groove so that two-phase abut against contact block it
Between formed with stopper slot, by the conflict block of setting, add and turn the strong point, then ensure that during installation, can be with
The convenient degree of installation is improved, the groove inwall of stopper slot is further arranged to arc-shaped, convex structure is improved and pacified
Flexible conflict between assembly parts, so as to reduce the possibility of stopper slot damage.
The utility model is further arranged to：It is in that angle is 60 ° between two adjacent stopper slots.
It is in that angle is 60 ° by using above-mentioned technical proposal, between two adjacent stopper slots, by by two adjacent stopper slots
Between be in that angle is arranged to 60 °, and the number of stopper slot is 6, ensure that being uniformly distributed for stopper slot, to improve installation
Convenient degree, and the uniform stressed of bolt head is ensure that, so as to improve the service life of bolt.
