As a preferable technical scheme of the utility model, the specification and the size of the protective shell are matched with those of the threaded rod, and two clamping rods are symmetrically distributed on the inner side of the protective shell.

As a preferred technical scheme of the utility model, the specification and the size of the spring are matched with those of the clamping rods, and the spring is arranged between the two clamping rods.

As a preferable technical scheme of the utility model, the inner side of the protective cover is provided with a clamping groove, and the position and the size of the clamping groove are matched with those of the clamping rod.

Compared with the prior art, the utility model provides an oil hole plug screw for oil exploitation equipment, which has the following beneficial effects:

1. this oil hole plug screw for oil development equipment can make the oil hole plug screw obtain good leakproofness when using through threaded rod, elastic layer, sealing ring, rubber circle, and when equipment production rocked, the elastic layer can reduce and rock the influence to the oil hole plug screw, improves the practicality of oil hole plug screw simultaneously.

2. This oil hole plug screw for oil development equipment can be through installing sealing ring and protective housing on the threaded rod through threaded rod, sealing ring, protective housing, kelly, spring, guard shield, and the outside at the protective housing is fixed with the guard shield to the block of rethread kelly and draw-in groove, and then can prevent that the oil hole plug screw from in the use, because the influence of dust moisture content etc. takes place to corrode, influences the oil hole plug screw normal use's condition and takes place.
