Abstract
The utility model discloses a wrench special for butterfly bolts. The wrench special for the butterfly bolts comprises a cylindrical clamp and a cylindrical handle penetrating through one end of the clamp. A pair of U-shaped clamping grooves used for clamping the butterfly bolts is formed in the other end of the clamp. The butterfly bolts are clamped by the clamping grooves, then the operation handle is rotated, the butterfly bolts are stressed evenly, torsion is increased, even female watch keepers with relatively small hand power can screw grounded butterfly bolts easily and unscrew screwed butterfly bolts easily, and the wrench special for the butterfly bolts is convenient to use, simple in structure and easy to manufacture.
Description
Technical field
The utility model relates to a kind of ingot Special bolt wrench.
Background technology
When the earth terminal of connecting wires is used earth stud to connect, solid and reliable for the earth terminal that guarantees earth connection, the ingot bolt must be tightened.But operating personnel's hand-power in practical operation, especially female person on duty's hand-power is limited, can not be by the ingot bolt tightening, thus affect the fastness of ground connection end ground connection.In addition, fastening ground connection ingot bolt is used hand-power also to be not easy dismounting when removing the earth terminal of earth connection.
When using the fastening and demounting bolt of spanner, because the ingot bolt mostly is pig copper casting or is the stainless steel welding, during the use spanner, due to the bolt strained inequality of ingot, easily cause the ingot bolt failure.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of ingot Special bolt wrench easy to use, simple in structure.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of ingot Special bolt wrench, and its key technology is: it comprises columnar jig and the cylindrical handle that is arranged in jig one end; At the other end of described jig, offer a pair ofly for blocking the U-shaped draw-in groove of ingot bolt, described draw-in groove top is hatch frame.
The beneficial effect that adopts technique scheme to produce is: draw-in groove of the present utility model blocks the ingot bolt, then rotating operating handle, make the bolt strained even and torsion increasing of ingot, even the female person on duty of hand-power less also can be easily by ground connection ingot bolt tightening with by fastening ingot Bolt dismantling, very easy to use, and simple in structure, easily make.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1, cylindrical handle; 2, jig; 3, draw-in groove.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to accompanying drawing 1, the utility model comprises columnar jig 2 and the cylindrical handle 1 that is arranged in jig 2 one ends, and jig 2 is stretched out at this cylindrical handle 1 two; At the other end of described jig 2, offer a pair of for blocking the U-shaped draw-in groove 3 of ingot bolt, described draw-in groove 3 upper openings, two corresponding settings of draw-in groove 3, the thickness of turning round handle of the size of draw-in groove 3 and ingot bolt is complementary, and blocks convenient getting final product.
