Abstract
The utility model relates to a reversible spanner provided with a handle, an outer reversing body and an inner hole. The reversible spanner is characterized in that the inner hole and the outer reversing body are arranged in an eccentric mode, and an inner reversing body is arranged in the inner hole. The outer edge of the inner reversing body is provided with a ratchet wheel groove engaged with a ratchet wheel pin. The utility model has the advantages of simple structure, high strength, convenient use and reversible capability.
Description
The utility model relates to a kind of hand-held tool, specifically a kind of spanner that reverses.
We know, the slow-witted spanner of hexagonal in oil well also uses when the flange disc changing-over always, and the moving angle of nut of revolution all will be lifted spanner during use, changes an individual angle and is inserted in nut more again and rotates, goes down so repeatedly, and troublesome poeration, efficient are very low.
The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple structure, spanner easy to use, reversible.
For achieving the above object, the utility model can be realized by following measure: it is provided with handle, external gyrorotor, endoporus, and its technical characterictic is to be set for the eccentric between endoporus and the external gyrorotor, is provided with interior revolving body in the endoporus, the outer of interior revolving body is provided with ratchet slot, ratchet pin and ratchet slot engagement.
The utility model also can be realized by following measure: ratchet slot is for semicircle.The front end of ratchet pin is a back taper.
The utility model is simple in structure, and intensity is big, and is easy to use, can reverse.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of ratchet pin.
Fig. 4 is the upward view of Fig. 3.
From Fig. 1, Fig. 2, Fig. 3, Fig. 4 as can be seen, the utility model handle 1 is structure as a whole with external gyrorotor 6, be processed with circular inner hole on the external gyrorotor 6, be set for the eccentric between endoporus and the external gyrorotor 6, the position that is endoporus is to the leading section position of external gyrorotor 6 off-centre, and circular interior revolving body 5 is installed in interior hole site, and interior revolving body 5 endoporus are hexagon, outer around interior revolving body 5 is processed with a plurality of ratchet slots 7, the cross section semicircular in shape of ratchet slot 7.External gyrorotor 6 radially be processed with pin-and-hole, pin-and-hole is equipped with ratchet pin 4, spring 2 from inside to outside successively, and sell and fill in 3 shutoff, 5 ° of shapes of front end addition back taper of ratchet pin 4, each gap is compensated, with the contact azimuth of assurance ratchet pin 4, prolong service life of the present utility model with ratchet slot 7.Effect bottom ratchet wheel pin 4 and ratchet slot 7 engagements at spring 2.When interior revolving body 5 was enclosed within on the bolt, revolving body 5 rotated in 6 drives of forward rotation external gyrorotor, backwards rotation external gyrorotor 6, and then external gyrorotor 6 can rotate with respect to interior revolving body 5.
When the utility model uses, interior revolving body 5 is enclosed within on the hex nut, twisting handle 1, the check configuration of revolving body 5 in utilizing, make angle of nut rotation, need not lift spanner, negative side's rotary handle 1, because the one-way of the certain tightness of nut and screw and the ratchet slot 7 of interior revolving body 5, ratchet pin 4 is return in ratchet slot 7, arrived certain angle, ratchet pin 4 is under spring 2 effects, be locked in next ratchet slot 7, so repeatable operation tightens bolt, same principle, with handle 1 counter-rotating, bolt can be unloaded.
Claims (3)
1, a kind of spanner that reverses, it is provided with handle, external gyrorotor, endoporus, it is characterized in that being set for the eccentric between endoporus and the external gyrorotor, is provided with interior revolving body in the endoporus, and the outer of interior revolving body is provided with ratchet slot, sour jujube pin and ratchet slot engagement.
2,, it is characterized in that said ratchet slot is for semicircle according to the described spanner that reverses of claim 1.
3, according to the described spanner that reverses of claim 1, the front end that it is characterized in that said ratchet pin is a back taper.
