Summary of the invention
The utility model provides a kind of two-way bolt tightener, and it can solve the production efficiency of prior art existence and hang down problems such as reaching waste of manpower.
The utility model has designed two-way bolt tightener in order to overcome the problems referred to above, utilizes this device, and producers can finish the fastening of bolt and nut by single one hand, and are simple, raise labour efficiency, and save manpower.
In order to reach the purpose that solves the problems of the technologies described above, technical solutions of the utility model are, a kind of two-way bolt tightener, comprise nut ratchet spanner and bolt ratchet spanner, it is characterized in that: the fastening and disassembly direction of described nut ratchet spanner and bolt ratchet spanner is a rightabout, on the described nut ratchet spanner long nut sleeve is housed, lag bolt cap sleeve tube is housed on the described bolt ratchet spanner, the together interlinked mechanism of interlock is housed between the body of rod of described nut ratchet spanner and described bolt ratchet spanner.
In the technical solution of the utility model, also have following supplementary technology scheme:
Described interlinked mechanism comprises length adjustment fixed cover, spring, pipe, motion bar and trip bolt, and described pipe is connected with described length adjustment fixed cover, and the socket of described length adjustment fixed cover is fixed on the body of rod of described bolt ratchet spanner; Described motion bar is fixed on the body of rod of described nut ratchet spanner by the installing hole suit of its end, described spring is contained in the described pipe, one end of described spring is connected with the end of described length adjustment fixed cover in pipe, described motion bar is inserted in the described pipe, and it inserts the end and is connected with described spring.
Described pipe and length adjustment fixed cover are by being threaded.
Described pipe and length adjustment fixed cover are one by being welded to connect.
Described length adjustment is fixing to be fixed on the body of rod of described bolt ratchet spanner by trip bolt.
Described motion bar is fixed on the body of rod of described nut ratchet spanner by trip bolt.
The utility model is adjusted to rightabout with the fastening direction of two ratchet wrenches, and when fastening, fixation is played on the right during the rotation of the left side, and fixation is played on the left side during rotation of the right, and along with fastening carrying out, nut moves right and screwed.In this process, spring is compressed, and finishes up to fastening.
Advantage of the present utility model and beneficial effect be, when the construction bolt nut, can realize single one-handed performance, and be applicable to the bolt and nut of different size, and convenient disassembly, simple and practical.Especially can when clamp nut, reach single one-handed performance, save manpower, enhance productivity.

The specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of two-way bolt tightener comprises nut ratchet spanner 1 and bolt ratchet spanner 4, and the fastening and disassembly direction of described nut ratchet spanner 1 and bolt ratchet spanner 4 is adjusted to rightabout.On the described nut ratchet spanner long nut sleeve 2 is housed, long nut sleeve 2 is used for adorning nut; Lag bolt cap sleeve tube 3 is housed on the described bolt ratchet spanner 4, and lag bolt cap sleeve tube 3 is used for adorning the turret head of bolt.The together interlinked mechanism of interlock is housed between the body of rod of described nut ratchet spanner 1 and described bolt ratchet spanner 4.
The concrete technical scheme of interlinked mechanism is: described interlinked mechanism comprises length adjustment fixed cover 5, spring 6, pipe 7, motion bar 8 and trip bolt 5-1,9.Described pipe 7 is socketed on the body of rod of described bolt ratchet spanner 4 by length adjustment fixed cover 5, and fixes with trip bolt 5-1; Described motion bar 8 is sleeved on the body of rod of described nut ratchet spanner 1 by the installing hole of its end, and it is fixing with trip bolt 9, described spring 6 is contained in the described pipe 7, and described motion bar 8 is inserted in the described pipe 7, and motion bar 8 inserts the end and is connected with an end of described spring 6.Described pipe 7 and length adjustment fixed cover 5 are by being threaded, and promptly pipe 7 one ends have internal thread, and length adjustment fixed cover 5 has one section external screw thread, and internal and external threads connects fuses both.The other end of spring 6 is connected with length adjustment fixed cover 5 male end.So just constitute two-way bolt tightener of the present utility model.
When using two-way bolt clamp device of the present utility model, earlier the long nut sleeve 2 on the nut ratchet spanner 1 is inserted in fastened nut, and the lag bolt cap sleeve tube 3 on the bolt ratchet spanner 4 is inserted on the turret head of bolt.Nut ratchet spanner 1 and bolt ratchet spanner 4 adopt ratchet spanner and fastening direction are adjusted to rightabout, are respectively clockwise and counterclockwise, can reach two-way fastening purpose.When fastening, can single singlehanded rotating bolt ratchet spanner 4, owing to have interlinked mechanism, nut ratchet spanner 1 is interlock together, and spring 6 is compressed, because the pulling of spring 6, motion bar 8 is done horizontal movement to the right with nut, until bolt with nut is fastened finishes.
Motion bar 8 and pipe 7 adopt matched in clearance, and the surface is coated with lubricating oil, so that the smooth and easy work of nut spanner.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
