Description

The ratchet box spanner

The utility model belongs to a kind of hand tools, is specifically related to a kind of ratchet box spanner.

Spanner is an instrument commonly used in the daily life, and its type is varied, as monkey wrench, fork spanner, double offset ring spanner, box spanner etc., their structures are different, and characteristics are respectively arranged on the function, and are simple in structure as monkey wrench, the scope of application is wide, but its swing angle spends greatly, generally all greater than 60 °; It is very inconvenient to use for very narrow workplace, those spaces, and double offset ring spanner, box spanner etc., are whenever twisted entirely during the Zhou Huixuan of garden doing that fastening action is obstructed, and all will take out spanner to retreat to put and twist, have both delayed man-hour, bother again.

The purpose of this utility model proposes a kind ofly also can handle very skillfully high efficiency, ratchet box spanner flexible and convenient to use in the space-constrained workplace.

This ratchet box spanner is pulled and mouthful is formed by pull body and sleeve that the two ends band is pulled mouthful, and pulling that the inwall of body two end plates mouth and outer wall that sleeve is pulled mouth all have can intermeshing ratchet.

During use, select corresponding jacket casing on nut or screw rod, be enclosed within sleeve and pull outside the mouth with corresponding body (the pulling mouth) end of pulling then, because ratchet is meshing with each other, the rotation of exerting oneself is pulled body and can be tightened, as will unclamp the time, the reverse side work that only needs pull mouthful and pull body with sleeve get final product, and the distribution of this cover spanner ratchet is many, and the minimum angle of circling round is little, the large size sleeve is pulled a mouthful outer wall 18 pawls that distribute, and minimum degree of circling round is 360 °/18=20 °.Small size sleeve is pulled mouthful outer wall 12 pawls that also distributed, and minimum swing angle is 360 °/12=30 °, therefore, and for narrow local very convenient to use in workplace.Simultaneously, because ratchet all to a direction, has only a direction ability stressed, opposite direction is then skidded, when the turn of the screw is obstructed and entirely during the Zhou Huixuan of garden, as long as the moving body of pulling of counter rotation slides into starting point by it and just can work on, therefore, its operating efficiency is that other spanner can not be compared.

This cover spanner can be processed into the plurality of specifications of different-diameter according to actual needs, to satisfy the needs that plurality of specifications nut, screw rod tighten or loosen, has efficient, convenient and practical characteristics.

Below in conjunction with accompanying drawing in detail the utility model is described in detail.

Fig. 1 is that the utility model is pulled the body schematic diagram.

Fig. 2 is that Figure 1A-A is to cutaway view.

Fig. 3 is that the utility model sleeve is pulled a mouthful main apparent direction schematic diagram.

Fig. 4 is that Fig. 3 overlooks the direction schematic diagram.

Among Fig. 1, pull body 1 two ends its have that diameter do not wait pull mouthfuls 2, it is pulled mouthful 2 inwalls and is processed into ratchet shape, as shown in Figure 2, Fig. 3 middle sleeve is pulled mouthful 3 outer walls and is had and pull mouthful intermeshing ratchet 4 of 2 inwalls, it is 8-14MM and 7-24MM series that the specification of its sleeve has diameter, purposes is very extensive, during use, select corresponding sleeve to pull mouth 3 and be enclosed within on nut or the screw rod, be enclosed within sleeve and pull outside the mouth with corresponding body (pulling mouth) 2 one ends of pulling then, because ratchet 4 is meshing with each other, firmly rotate and pull body and can tighten, as will unclamp nut or screw rod the time, the reverse side work that only needs pull mouthful and pull body with sleeve gets final product.
