Equipped with the positioning head；The handle is equipped with hook groove close to the side of the fixed plate, is plugged with the hook in the hook groove
The end of head, the gib head is fixed in the handle by screw and nut；The inside of the handle is equipped with described for holding
The storage chamber of screwdriver, the other end inner wall of the storage chamber are equipped with screw thread and are connected with sealing cover, the screw together
The both ends of knife are respectively equipped with drill bit and screw thread two.
Preferably, protrusion forms thimble, the insertion hole of the thimble and iron chair forward for one end of the positioning head
It is used cooperatively.
Preferably, the gib head can be rotated around the screw, the gib head is used cooperatively with the positioning head.
Preferably, the drill bit is arranged towards the sealing cover.
Preferably, the screw two is used cooperatively with the screw thread one, the outer diameter of the screwdriver body is less than institute
State the internal diameter of storage chamber.
Preferably, the sealing cover is equipped with link block towards one end of the storage chamber, the link block is equipped with
The screw thread three being used cooperatively with the screw thread one, the link block are made of rubber material.
Preferably, being socketed with protective case on the handle, the surface of the protective case is equipped with anti-skid chequer.
The utility model has the following beneficial effects: it is reasonable in design, solve the problems, such as that spring crosses installation, user
Just, effect is obvious, can accurately control and be inserted into the distance between hole end surface with iron chair on the inside of the small arc-shaped of spring tail portion；One object is more
With, it is also used as screwdriver and uses, easy to carry, saving space.
