Preferably, one end of the big end of the arc-shaped part is close to the retainer ring, and the small end of the arc-shaped part is attached to the surface of the polish rod.
Adopt above-mentioned technical scheme, through the microcephaly one side of arc portion and the nearly device of pegging graft to make its inside of the nearly device of first threaded rod grafting that can be better, thereby make it laminate as much as possible.
Preferably, the surface of the plug is provided with a clamping groove, and the clamping groove is formed in a circular ring shape.
Adopt above-mentioned technical scheme, be provided with the joint groove through the one side at the bayonet joint to when the device is pegged graft near mechanical inside, can cup joint the rubber band, thereby when making first threaded rod insert near device inside, have fine fastening effect.
Preferably, the diameters of the first threaded rod and the second threaded rod are equal, and the diameters of the plug connector and the fixed head are smaller than the diameters of the first threaded rod and the second threaded rod.
Adopt above-mentioned technical scheme, diameter through first threaded rod and second threaded rod is the same to the convenience is regular to the nut size, and bayonet joint and the fixed head that sets up at both ends simultaneously make things convenient for laying and pegging graft of device, thereby makes the installation convenience more of this bolt.
