The diameter of plate is less than the diameter of upper ladder end face, and the pillar is arranged on the center of limiting plate, and the perforation and pillar are horizontal
Section is disposed as circle, and the strut ends through perforation are connected by vertical locating part with plug housing into rotation.
Further, when the plug housing is used in screw thread insertion casing coupling, the described sleeve pipe box cupling other end and sleeve pipe
Thread connection.
Further, the vertical locating part is set to nut, the nut and pillar thread connection.
Further, the agent structure also includes baffle plate, and the baffle plate is fixed with plug housing bottom end seal.
Further, the lateral wall of the upper capping and limiting plate is disposed as smooth, polished face.
Further, the height between the upper ladder and downstairs is less than the height of limiting plate.
A kind of spanner for tubing and casing plug, the spanner sets cascade groove, the shapes and sizes of the groove
Match with the combined shaped and size of the upper capping and antitheft boss.
Further, the groove includes the different big holes and small sircle hole of pore size, and the big hole and small sircle hole are not
With one heart.
Further, the spanner top also sets up projection, and the raised laterally setting second is perforated.
Relative to prior art, a kind of tubing and casing plug of the present invention has the advantage that：
With antitheft boss, and the upper capping decentraction of antitheft boss and plug housing, it is ingenious to be reached using eccentric structure
The effect do not dismantled to non-spanner, plays antitheft effect；
Perforation and pillar and upper capping and boss are disposed as circle, prepare simply, easy to use.
