Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention based on the embodiments of the present invention.

Examples

Referring to fig. 1-4, the present invention provides the following technical solutions:

an explosion-proof dual-purpose knocking double offset ring spanner, includes:

a wrench head 1;

the first handle 2 is fixedly arranged on the circumferential surface of the wrench head 1;

the second handle 3 and the first handle 2 are symmetrically and fixedly arranged on the circumferential surface of the wrench head 1;

the hammer head 4 is fixedly arranged at the end part of the second handle 3 and is used for knocking;

the sliding chute 12 is communicated and arranged on the wrench head 1 and the first handle 2; and

the adjusting mechanism is arranged on the first handle 2, is in sliding fit with the sliding groove 12 and the wrench head 1, and is used for adjusting the diameter of a wreath of the wrench head 1.

In this embodiment: adjust wrench head 1's wreath bore through adjustment mechanism for wrench head 1 can also twist the bolt that is less than per se wreath bore on can only twisting the basis of changeing the same bolt with model per se, and application range is wider, meets the difficult condition of twisting the commentaries on classics of bolt and can use earlier tup 4 to strike the bolt and make its not hard up back reuse wrench head 1 twist the commentaries on classics during the dismantlement.

Specifically, the adjustment mechanism includes:

the rotating shaft hole 13 is formed in the first handle 2 and communicated with the sliding groove 12;

the limiting rotating shaft 5 is rotatably arranged on the rotating shaft hole 13;

the movable clamping block 6 is sleeved on the surface of the limiting rotating shaft 5 and slides in the sliding groove 12; and

spring 7, fixed locate between removal clamp splice 6 and first handle 2, wherein:

when the spring 7 is in an initial state, the movable clamping block 6 is positioned outside the wrench head 1.

In this embodiment: the movable clamping block 6 is provided with a sleeve hole 14, the surface of the limiting rotating shaft 5 is sleeved with the sleeve hole 14, before the wrench is used, when the spring 7 is in an initial state, a chuck of the movable clamping block 6 is positioned on the outer side of the wrench head 1, when the plum blossom caliber of the wrench head 1 needs to be adjusted, the first handle 2 is held by a hand and the hand behind the movable clamping block 6 is tightly held in a palm direction, the chuck of the movable clamping block 6 can slide into the wrench head 1 from the outer side of the wrench head 1, the first handle 2 is continuously held after the clamping of the parts such as the bolt and the like by matching with the wreath of the wrench head 1, the bolt can be rotated after rotating around the bolt, the finger is loosened after the installation or the disassembly of the bolt is completed, the movable clamping block 6 can restore to the initial state under the elastic acting force of the spring 7, and the chuck slides to the outer side of the wrench head 1 from the wrench head 1.

Preferably, the movable clamping block 6 is provided with anti-skid threads 10.

In this embodiment: when the first handle 2 is gripped and the clamping block 6 is moved, fingers need to exert force, friction force can be increased by arranging the anti-skidding threads 10, the hands are prevented from skidding, the situation that the fingers slip when the bolt is screwed is avoided, and the safety of personnel is ensured.

The top of the hammer head 4 is provided with a first groove 8; and

the bottom of the hammer 4 is provided with a second groove 9.

In this embodiment: first recess 8 and second recess 9 that the size is different have been seted up with the bottom in 4 tops of tup, if meet with parts such as its size unanimity bolt or nut at the during operation, then can avoid adjusting the wreath diameter of wrench end 1 to use wrench end 1, save the trouble of regulation.

Because need rotate first handle 2 hard when screwing the nut, the finger needs a impetus hard, so stress groove 11 has all been seted up to the top and the bottom of first handle 2 and second handle 3 symmetry, and first handle 2 and second handle 3 all can regard as the arm of force and can use simultaneously.

In this embodiment: when the first handle 2 is held by a hand to rotate, fingers can be placed in the stress groove 11, so that the fingers can be supported at the edge of the stress groove 11 to be held more tightly and stably during rotation, and meanwhile, the first handle 2 can be held by one hand and the second handle 3 can be held by the other hand to rotate forcibly, so that parts such as bolts can be screwed or loosened more easily.

The utility model discloses a theory of operation and use flow: when installing or dismantling the bolt, during parts such as nut, if the specification of parts such as nut is unanimous with wrench head 1 wreath diameter, directly use wrench head 1 can, if the specification of parts such as nut is unanimous with first recess 8 or second recess 9 on tup 4, directly use first recess 8 or second recess 9 can, if the specification of parts such as nut is less than wrench head 1 wreath diameter also with first recess 8 and second recess 9 when inconsistent, just need to adjust wrench head 1's wreath diameter, hold first handle 2 and removal clamp 6 back hand point to palm direction and tightly hold with the hand simultaneously, the chuck of removal clamp 6 will slide and reduce its wreath diameter in wrench head 1, after carrying out the centre gripping to parts such as bolt, put the thumb on atress groove 11 when continuing to hold first handle 2 and removal clamp 6, then rotate its part such as around the part such as nut and can rotate the part and install or dismantle, if discover not to screw up when dismantling, can use its handle 2 to screw up the bolt 4 earlier and can also make its handle 2 not be more convenient when using the first handle to screw up again, it simultaneously and the handle can more easily.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
