Description

A kind of Novel universal ratchet spanner

Technical field

The utility model relates to a kind of spanner, especially a kind of Novel universal ratchet spanner.

Background technology

Spanner is the instrument that people relatively commonly use, but in use, in order to adapt to bolt and the nut of different size, people often need the spanner wearing different size, not only weigh, and very inconvenient, and in use, especially, under requiring larger condition to handle pendulum angle, spanner needs constantly handling, very inconvenient.

As can be seen here, prior art needs to improve further and improve.

Summary of the invention

A kind of Novel universal ratchet spanner, comprise Wrench head, driving shaft, ratchet, cover plate, plectrum, handle and sleeve, described Wrench head is cylindrical, there is a hexagonal hole lower end, and upper end is provided with a driving wheel, and driving wheel interlude has cylindricality striped, the lower end of driving wheel is an axle, have a foursquare hole in the middle of the axle of driving wheel upper end, cover plate is fixed on the upper end of driving wheel by four screws, and the axle of driving wheel upper end is arranged in the circular port in the middle of cover plate.

Described driving wheel side is provided with a ratchet, the shape of ratchet is crescent, the medial surface of ratchet there is the striped of cylindricality, ratchet top and bottom are respectively fixed with an axle, ratchet lower end axle is arranged in the ratchet holes of Wrench head upper end, ratchet upper shaft is through a hole of cover plate, plectrum is fixed by a pin to the upper end of ratchet upper shaft, the rear side of ratchet mid portion has two grooves, ratchet rear is provided with a spherical post, ball head column withstands in a groove of ratchet, and the rear end of ball head column is provided with a spring.

Described sleeve stack up be placed on Wrench head lower end hexagonal hole in, the cross section in the middle of handle be circle, and handle has an elbow bend, respectively there is one section of square cylinder at handle two ends.

Owing to have employed technique scheme, the beneficial effect acquired by the utility model is:

1. in use, sleeve can be superimposed and put the hexagonal hole of Wrench head lower end into, by superposition sleeve quantity and the difference of size, adapts to bolt or the nut of different size, makes to carry and very easy to use.

2. in use, stir plectrum, make one end of ratchet lean against on driving wheel, ball head column withstands in a groove of ratchet rear end, pulls handle by positive direction, and Wrench head can be driven to rotate, and toward pulling handle in the other direction, Wrench head does not rotate.

Detailed description of the invention

As depicted in figs. 1 and 2, a kind of Novel universal ratchet spanner, comprise Wrench head 1, driving wheel 2, ratchet 7, handle 9 and sleeve 8, Wrench head 1 is cylindrical, and upper end is provided with driving wheel 2, and driving wheel 2 interlude has cylindricality striped, the lower end of driving wheel 2 is fixed with installation shaft, have a foursquare hole in the middle of the axle of upper end, cover plate 6 is fixed on the upper end of driving wheel by four screws 4, and the axle of driving wheel 2 upper end is arranged in the circular port in the middle of cover plate 6.

As shown in figures 1 and 3, the side of described driving wheel 2 is provided with ratchet 7, and the shape of ratchet 7 is crescent, the medial surface of ratchet 7 there is cylindricality striped, the lower end of ratchet is fixed with an installation shaft, and the upper shaft of ratchet 7 is through cover plate 6, and the upper end of axle is provided with a plectrum 3 by pin; The groove that the rear end of ratchet 7 has two transition mild, groove back has a ball head column 10 to withstand in a groove, and ball head column 10 back is provided with spring 11.

As shown in Figure 1 and Figure 4, there is a hexagonal hole lower end of described Wrench head 1, and sleeve 8 is hexagon, and the sleeve of different size can be superimposed and put into the hexagonal hole of Wrench head 1 lower end.

Operation principle of the present utility model is: when specifically using, plectrum 3 is pushed a position, one end of ratchet 7 leans against on driving wheel 2, and ball head column 10 is under the effect of spring 11, withstand in a groove of ratchet 7, inserted one end of handle 9 in the square hole of driving wheel 2 upper shaft, forward pulls handle 9, and ratchet 7 is stuck on driving wheel 2, driving wheel 2 is made to drive Wrench head 1 to rotate forward, oppositely pull handle 9, driving wheel 2 and ratchet 7 relative sliding, can not drive Wrench head 1 to rotate; Plectrum 3 is pushed another position, the other end of ratchet 7 leans against on driving wheel 2, ball head column 10 is under the effect of spring 11, withstand in another groove of ratchet 7, forward pulls handle 9, ratchet 7 and driving wheel 2 relative sliding, handle 9 can not drive Wrench head 1 to rotate, oppositely pull handle 9, ratchet 7 leans against on driving wheel 2, makes driving wheel drive Wrench head 1 to reversely rotate.

The part do not addressed in the utility model adopts or uses for reference prior art and can realize.

In description of the present utility model, it will be appreciated that, term " lower end ", " upper end ", " rear end ", " on ", the orientation of the instruction such as D score, "front", "rear" or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
