Enormous benefits.
Utility model content
The purpose of this utility model be to provide it is a kind of it is convenient tighten and anti-loosening screw, set by the side in movable block
The spike set, when use, are heavily hit embedded body surface, bolt and workpiece are kept opposing stationary, by circular hole and bolt head
The six rib slots in portion are matched with six prismatic protrusions of screw rod bottom, and bolt head can be convenient for carrying out tightening behaviour using tool with movable block
Make so that bolt is convenient to be screwed up with nut, fastens；A certain amount of lubricating oil can be added in oil-way during bolt use, recessed
Slot design can prevent from causing lubricating oil to drip during installation bolt, while can store a part of lubricating oil, to list of bolts
Face carries out continuous lubrication, prevents from getting rusty and corrode, and whole device setting is reasonable, be greatly improved fixing bolt the safety used,
Convenience.
To achieve the goals above, the utility model is realized using following technical scheme：It is a kind of convenient to tighten and locking
Dynamic screw, including bolt head, the bolt head are internally provided with six rib slots, and the side of the bolt head is provided with activity

Bar is filled, coordinates at the top of the mounting rod and elastic washer is installed, the bottom of the screw rod is provided with six prismatic protrusions, the screw thread
It is used cooperatively with nut.
Further, the movable block is internally provided with circular hole, and the side of the movable block is provided with connecting shaft, described
The bottom of movable block is provided with spike.
Further, the bolt head bottom is internally provided with oil-way, and the top of the nut is provided with coarse
Surface.
Further, the connecting shaft is made by high-carbon steel material, and the six ribs slot is matched with six prismatic protrusions.
The beneficial effects of the utility model are：
1, by the spike being arranged in the side of movable block, when use, is heavily hit embedded body surface, by bolt and workpiece
It keeps opposing stationary, improve the installation effect of bolt and uses fixed effect.
2, by be arranged the six prismatic protrusions and screw head of six rib slots inside circular hole and bolt head and screw rod bottom with
The bulk that movable block is formed so that bolt is convenient to be screwed up with nut, fastens.
What 3, elastic washer improved bolt installation process agrees with effect, it is ensured that the stationarity of installation.
4, oil-way can store a part of lubricating oil when mounted, persistently be lubricated antirust to bolt, improve spiral shell
The using effect of bolt.
