Description

A kind of combination hammer with ratchet spanner

Technical field

The utility model belongs to hardware & tools field, relates to a kind of combination tool, is specially a kind of combination hammer with ratchet spanner.

Background technology

Spanner is a kind of conventional installation and removal instrument.Utilize lever principle to twist bolt, screw, nut and other screw threads and tightly hold the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is usually shaped with clamp holder portion and applies external force shank and apply external force in the one or both ends of shank, just can twist opening or trepanning that bolt or nut hold bolt or nut.During use, threadingly direction of rotation applies external force at shank, just can twist bolt or nut.

Existing spanner is divided into fixed and movable two kinds, and fixed spanner for fixing nominal diameter effect, and can not can only rotate backward in the process used, and adjusts spanner rotational angle and again snap in after needing the securing member of effect of exiting; So, need the spanner being equipped with multiple different model, and use also inconvenient.

Movable spanner is divided into two kinds: a kind of is that spanner tooth is adjustable, and it can adapt to the securing member of different model within the specific limits; Another kind is that rotation direction can be adjusted, and it is in the process of work, and rotate forward after can oppositely dallying firmly, it is represented as ratchet spanner again; But this ratchet spanner is all fixing model size, its structure is complete lasso form; Have no idea at present to use several for the effect of two kinds of monkey wrenches in a spanner.There is many places to be modified in prior art about spanner.

In addition, while use spanner, often can use hammer, therefore hammer also needs to carry, the burden of carrying as this increased, and the applicability of single tool is single.

Utility model content

For realizing above object, the technical solution adopted in the utility model is: a kind of combination hammer with ratchet spanner, it comprises the hammer head (803) of body of recouping losses (8) and the setting of its end, the other end of described body (8) is also provided with driving end (9), described driving end (9) is half arcuate structure, be fixed with spanner hook (5) rotationally by rivet (6) below its arcuate end, the inner side of spanner hook (5) is set to polygon half coil structures connected; The arranged outside of spanner hook (5) is arc-shaped structure; Contact with the outside of spanner hook (5) and be provided with resetting-mechanism, it comprises the spring overcoat (2) be fixed on body (8), be embedded in the spring inner sleeve (3) in spring overcoat (2), and the spring (1) be arranged among spring overcoat (2) and spring inner sleeve (3), and be fixed with ballhead (10) at the end of spring inner sleeve (3), the outer arc shape movable contact of described ballhead (10) and spanner hook (5).

Further, described body (8) is divided into dismountable two parts, comprises spanner handle (801) and hammer handle (802), and the two is matched by threaded rod (805) and thread bush (806).

Further, on described body (8), also cover has taper knob (7), and its outer surface arranges some anti-slop serrations for anti-skidding effect (701).

Further, the spring overcoat (2) of described resetting-mechanism is fixed in described taper knob (7).

Further, the circular arc end of the driving end (9) of described body (8) is provided with spring limit for length card (4) for blocking ballhead (10).

Further, the end face that described spring limit for length card (4) contacts with ballhead (10) is provided with anti-slip tank (401).

Further, tooth-shape structure is provided with outside the circular arc of described driving end (9).

The beneficial effects of the utility model: a kind of combination hammer with ratchet spanner of the utility model, possesses spanner and hammer function simultaneously, save and carry space, applicability is wide; Securing member in a big way in endoadaptation different model specification limit uses, and automatically adjusts locking, and without the need to artificial adjustment, the effect simultaneously possessing ratchet spanner rotates forward firmly after providing and oppositely dallying again, simple and practical convenient.

1, by hammer and spanner integrated, save space, add the applicability of single tool, utilize instrument more efficiently.

2, adjustment and the securing member adapting to different model in a big way, be applicable to multiple use occasion, solve carrying and changing troublesome problem of single model spanner.

3, automatically adjust locking in use, without the need to artificial adjustment, without the need to manual rotation's runner, save regulation time, and self-adaptative adjustment is more accurate, without the need to repeatedly adjusting, does not limit by runner pitch.

4, there is effect of ratchet spanner simultaneously: rotate forward again after namely oppositely idle running is provided firmly, without the need to exit effect securing member after adjust spanner rotational angle and again snap in, save the fastening time and more can adapt to the narrow and small place of the restriction of securing member locus.

5, the utility model adopts resetting structure, controls the scope of activities of spanner hook, solves spanner hook in prior art uncontrolled, the problem of easily rocking.

6, the utility model structure is simple, and low cost is easy to operate, practical.

Detailed description of the invention

The technical solution of the utility model is understood better in order to make those skilled in the art; below in conjunction with accompanying drawing, the utility model is described in detail; the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.

As shown in Figure 1-2, concrete structure of the present utility model is: a kind of combination hammer with ratchet spanner, it comprises the hammer head 803 of recoup losses body 8 and the setting of its end, the other end of described body 8 is also provided with driving end 9, described driving end 9 is half arcuate structure, be fixed with spanner hook 5 rotationally by rivet 6 below its arcuate end, the inner side of spanner hook 5 is set to polygon half coil structures connected; The arranged outside of spanner hook 5 is arc-shaped structure; Contact with the outside of spanner hook 5 and be provided with resetting-mechanism, it comprises the spring overcoat 2 be fixed on body 8, be embedded in the spring inner sleeve 3 in spring overcoat 2, and the spring 1 be arranged among spring overcoat 2 and spring inner sleeve 3, and be fixed with ballhead 10 at the end of spring inner sleeve 3, the outer arc shape movable contact of described ballhead 10 and spanner hook 5.

Preferably, described body 8 is divided into dismountable two parts, comprises spanner handle 801 and hammer handle 802, and the two is matched by threaded rod 805 and thread bush 806.

Preferably, on described body 8, also cover has taper knob 7, and its outer surface arranges some anti-slop serrations 701 for anti-skidding effect.

Preferably, the spring overcoat 2 of described resetting-mechanism is fixed in described taper knob 7.

Preferably, the spring limit for length that the circular arc end of the driving end 9 of described body 8 is provided with for blocking ballhead 10 blocks 4.

Further, described spring limit for length blocks 4 end faces contacted with ballhead 10 and is provided with anti-slip tank 401.

During concrete use, to use the function of hammer, taking out the utility model, holding body 8, hammer head 803 is aimed at the object treating hammering;

To use the function of ratchet spanner, eave tile groove 501 on spanner hook 5 is stuck on to be tightened, then can realize: the taper knob 7 holding spanner, stir the spanner hook 5 of spanner, make to block securing member that is to be tightened or that unclamp inside it, under the effect of spring 1, ballhead 10 withstands the outer arc shape of spanner hook 5, limit after it continues and turn, realize self-locking; Around fastener rotation body 8, realize direction force; Because spanner hook 5 is movable spacing, after rotating a direction, the certain angle that can dally in the other direction carries out forward force again, so, namely reaches the effect of ratchet.
