Description
Technical field
The utility model system is relevant for a kind of ratchet spanner stopping means, more detailed it, particularly, see through and set up a stopping means at the rotation effect of ratchet D head, this D head of control must be rotated or spacing switching state.
Background technology
The structure of at present general box spanner, mainly be divided into ratchet-type and fixed two kinds, wherein fixed box spanner unloads on the application of force of operation in lock, need rotation with nut (bolt) and spanner relational angle to change and constantly clamping and conversion gesture again, cause it to implement to go up quite inconvenience and trouble, but can possess the advantage of spanner acrotorque output.
And the box spanner of ratchet-type is when the lock that carries out nut (bolt) unloads operation, system can unidirectional rotating characteristic by it, after making it rotate to suitable angle, can dally circles round again replys former application of force angle, do not need again conversion gesture constantly and clamping again so that make its lock unload operation, and then obtain comparatively easily lock and unload operation and implement, but because the rotation of ratchet spanner only relies on fastening of ratchet in the D head, so exportable torsion then is lower than fixed box spanner.
Therefore so, above-mentioned two kinds of box spanner structures all have its pluses and minuses, and these two kinds of sleeve barrel tools also frequently are used in industry and the daily life, should remain to manage to solve improvement.
The utility model content
Main purpose of the present utility model provides a kind of ratchet spanner stopping means, particularly at the rotation effect of ratchet D head, sees through and sets up a stopping means, and this D head of control must be rotated or spacing switching state.
To achieve these goals, ratchet spanner stopping means of the present utility model is made up of a spanner handle and a driving end, be characterized in, be to comprise on its structure:
The front end of driving end is provided with placement section and the ratchet hole that is provided with for the D head, and the placement section rear end is provided with a storage tank that communicates again, and digs downwards in storage tank and establish a perforation, and the bottom of this perforation then is formed with a groove;
One stopping means, be installed in the perforation of driving end, it is that a resisting block is arranged, and be extended with a cylinder in resisting block below, and the center section part of cylinder is provided with a hole slot, then is equipped with a spring in the hole slot, and covers a cap post in the outer end of spring cover, and dig and is provided with a circular groove groove at the square body place under the cap post, and must be in the circular groove groove in conjunction with a C shape buckle device;
One D head, it is installed in the placement section and the place, ratchet hole of driving end, and the scarce portion that the outer rim of its cover plate system has array to be provided with;
By pressing down stopping means its resisting block is positioned in the storage tank, and the rotation of restriction D head makes its resisting block break away from storage tank through raising stopping means again, discharge the cover plate of D head according to this, make ratchet spanner carry out the revolution operation.
The space system that the scarce portion of this cover plate links to each other with storage tank presents the space, location of stopping means resisting block.
The cap post of this stopping means is outwards pushed by spring, and is the state of pushing against with the inwall of boring a hole.
The diameter range of this C shape button is greater than the diameter range of perforation.
Cylinder place between this hole slot and circular groove groove must be embedded a steel ball.
The utlity model has following useful technique effect:
1,, the D head of giving ratchet spanner is switched on rotate or spacing state through being installed in the stopping means of driving end and the counter structure of D head.
2, see through to adjust the location of stopping means, make the rotation or the spacing state of control ratchet spanner D head, reach according to this and have big torsion output or unidirectional rotating use effect concurrently, and increase the value of its commercial use.

The specific embodiment
Reach the aspect relevant for structure composition of the present utility model, technological means and effect, sincerely cooperate graphic the giving again of preferred embodiment further to specify for example in the back:
At first, see also Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, ratchet spanner 10 of the present utility model is on structural design, mainly formed by a spanner handle 11 and a driving end 12, and driving end 12 front ends are provided with for D 20 placement section 13 and the ratchet holes 14 that are provided with, and placement section 13 rear ends are provided with a storage tank that communicates 15 again, and dig downwards in storage tank 15 and establish a perforation 16, the bottom of this perforation 16 then is formed with the groove 17 of a broad, then is equipped with a stopping means 30 in this perforation 16.
In addition, above-mentioned stopping means 30 mainly system has a resisting block 31, and be extended with a cylinder 32 in resisting block 31 belows, and the center section part of cylinder 32 is provided with a hole slot 33, then be equipped with a spring 34 in the hole slot 33, and cover a cap post 35 in the outer end of spring 34 cover, cylinder 32 places of these hole slot 33 belows are embedded with a steel ball 36 again, and dig again in 36 times square body 32 places of steel ball and to be provided with a circular groove groove 37, and must be in conjunction with C shape button 38 devices in the circular groove groove 37.
Again, the scarce portion 22 that cover plate 21 outer rims of above-mentioned D 20 system has array to be provided with is the space, location that can present stopping means 30 resisting blocks 31 and should lack the space that portion 22 links to each other with storage tank 15.
Moreover, this stopping means 30 is in perforation 16, this cap post 35 will outwards pushing because of spring 34, and be the state of pushing against with perforation 16 inwall, 36 location that can strengthen stopping means 30 of this steel ball again, in addition the C shape button 38 of below because of diameter range greater than perforation 16, so can prevent the disengaging of stopping means 30; Therefore, as Fig. 1 and shown in Figure 4, this stopping means 30 is to present pressed status, and 31 of this resisting blocks are positioned in storage tank 15 and the scarce portion 22 formed spaces, and then reach the effect of the rotation of restriction D 20, so can meet the operational requirements of big torsion output.
In addition, please consult Fig. 5 and shown in Figure 6 again, this stopping means 30 sees through and raises its resisting block 31 and break away from the space that storage tanks 15 and scarce portion 22 form, and this moment, D 20 21 of cover plates presented release conditions, and is like this then can normally use the revolute function of ratchet spanner.
In sum, the utility model system provides ratchet spanner to produce the variation of switching D head location fast or discharging by the composition design of mechanism, give ratchet spanner according to this and have big torsion output or unidirectional rotating use effect concurrently, really can effectively solve the disappearance that general box spanner uses, also significantly increase the convenience of operation, generally speaking, has industrial utilization.
