Abstract
The utility model discloses a multi-functional ratchet wrench, which adopts the engaging means of a double-way ratchet. The double-way ratchet are fixed by a positioning shaft. The two ends of the double-way ratchet are respectively released from the double-way ratchet and engaged with the double-way ratchet. The non-engaging end of the double-way ratchet is exposed on the outer side of the main body of the wrench. One end of the double-way ratchet is always engaged with the double-way ratchet under the action of a steel ball and spring force. Besides, screw bolts are ensured to be tightened under the force and the slip of return stroke can be realized. The multi-functional ratchet wrench has the advantages of simple structure, easy operation and strong applicability.
Description
The utility model relates to a kind of high efficiency multi-functional ratchet spanner, belongs to hand tools.
At present, generally the ratchet spanner of Shi Yonging can only folk prescription to use, as changing direction, must make 180 ° of spanner upsets earlier, though have can change direction, moment is little, can not tighten or loose bolts, therefore use very inconvenient, inefficiency.
The purpose of this utility model just provides a kind of convenience, high efficiency multi-functional ratchet spanner, and it has overcome the deficiency of prior art, and has and change direction and make things convenient for, saves time, easily and have calibration workpiece bolt hole and location function such as conveniently is installed.
The utility model is achieved in that the engagement system that adopts two-way ratchet and two-way ratchet, and two-way ratchet center has plum blossom hole or square opening, and plum blossom hole can be made the plum blossom spanner; The spanner that has square opening can be changed tool heads, makes the sleeve spanner, realizes and commercially available sleeve spanner universal fit.Two-way ratchet places in the main body, and spacing by location lid, two-way ratchet is fixed by a locating shaft, and an end that links to each other with handle in the main body of ratchet spanner has central channel, and stage clip is housed in the groove, and the stage clip top is provided with a steel ball, and steel ball is between two-way ratchet and stage clip.
Two-way ratchet one end and ratchet always are in engagement, and it is convenient that two-way ratchet changes application of force direction, and center of effort is by the locating shaft center, and two-way like this ratchet can bear big moment.
The non-end of engagement of two-way ratchet exposes outside ratchet spanner body shell, when needing to change direction, as long as press exposed end, the positioning end compressing steel ball and the stage clip of so two-way ratchet, then the end of engagement of two-way ratchet is separated from two-way ratchet, an originally exposed end and two-way ratchet engaged, this process is play the guiding role by steel ball.
Calibration bolt hole and easily workpiece being located when installing, the utility model is tapered with handle design, can improve work efficiency.
The utility model is compared with conventional art, following advantage is arranged: the engagement system of two-way ratchet and two-way ratchet makes ratchet be easy to change and is subjected to force direction, and center of effort is by two-way ratchet locating shaft center, so ratchet can bear bigger moment, and applicability is strong.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is further described.
Accompanying drawing is the structural representation of the utility model embodiment.
Description of drawings is as follows:
1, main body, 2, location lid, 3, two-way ratchet
4, two-way ratchet 5, locating shaft, 6, steel ball
7, stage clip 8, handle
Main body (1) is a housing, in two-way ratchet (3) is housed, two-way ratchet (3) is by location lid (2) location, the center has quincunx hole, two-way ratchet (4) is fixing by locating shaft (5), open stage clip (7) is housed in the groove at main body (1) center, stage clip (7) top is provided with steel ball (6), and steel ball (6) is in the middle of two-way ratchet (4) and the stage clip (7).
The a end or the b end of two-way ratchet (4) all can be exposed at outside main body (1) housing.
Handle (8) is a taper, is made of one with main body (1).
The engagement place of two-way ratchet (4) and two-way ratchet (3), the force direction that is subjected to of promptly two-way ratchet (4) passes through the center of locating shaft (5), and two-way like this ratchet can bear big moment.
Two-way ratchet (4) guarantees that under the effect of steel ball (6) and stage clip (7) two-way ratchet (4) and two-way ratchet (3) always are in engagement, can tight a bolt when also guaranteeing the application of force, and can realize that backhaul skids.
During use, coupling box on the two-way ratchet (3) is enclosed within on six square toes of bolt, make bolt tighten (dextrorotation bolt) clockwise, only need a end of two-way ratchet (4) on the spanner is pressed, make its a end and two-way ratchet (3) engagement, the application of force just can tight a bolt rapidly then, the reverse application of force, two-way ratchet skids.If make bolt tighten (left-handed bolt) counterclockwise, only the b end of two-way ratchet (4) need be pressed, itself and two-way ratchet (3) are meshed, this moment, a end can be thrown off, and the counterclockwise then application of force just can tight a bolt rapidly.
The utility model reasonably uses mechanics principle, arrange dexterously the combination of pawl-and-gearing, realized to bear bigger moment and turning to convenience with very little pawl structures, operate very simple, and handle design is tapered, provide operational convenience to the user, simultaneously, improved operating efficiency.
The utility model is simple in structure, and is reasonable in design, processes easily and promotes.
Claims (3)
1, a kind of ratchet spanner, constitute by main body, location lid, ratchet, ratchet and handle, it is characterized in that described ratchet is two-way ratchet, ratchet is two-way ratchet, and it also comprises locating shaft, steel ball and stage clip, the end center that main body links to each other with handle is provided with groove, stage clip is housed in the groove, and there is steel ball the stage clip upper end, and ratchet is located by locating shaft, ratchet and ratchet engaged, steel ball are located between ratchet and the stage clip.
