However, both the L-shaped wrench and the T-shaped wrench have the problem that one type of bolt corresponds to one wrench, the universal performance is poor, when bolts of various specifications are needed, a large number of wrenches of different models and specifications need to be carried, the wrenches are tedious and troublesome, the selection and storage are inconvenient, the working efficiency is reduced, the wrenches are very easy to lose, in addition, during operation, a workpiece is sleeved on the wrench, after the wrench is rotated for a certain angle, the wrench needs to be dismounted and returned, and the workpiece can be continuously rotated after being sleeved again, so that the wrench is very inconvenient.
Disclosure of Invention
The utility model provides an above-mentioned problem, provide a novel hexagonal ratchet spanner in.
In order to achieve the purpose, the invention adopts the technical scheme that:
the utility model provides a novel hexagonal ratchet spanner in, its characteristic includes handle, hexagonal subassembly in, spanner body and ratchet, the handle passes through interior external screw thread connection with the spanner body, the spanner body is bottom open structure, and its inner wall is equipped with the pawl, the bottom of spanner body is connected through interior external screw thread with the end cover, the ratchet cooperatees with the pawl, the terminal surface of ratchet links to each other with a terminal surface of connecting piece, another terminal surface and the hexagonal subassembly of connecting piece pass through threaded connection, hexagonal subassembly in include a plurality of hexagonal prism cover bodies and a hexagonal prism entity, the mutual sliding fit of accessible recess between the hexagonal prism cover body, but hexagonal prism entity and hexagonal prism cover body sliding fit link to each other through the spring between hexagonal prism entity and the connecting piece.
As the utility model discloses a further optimization, the screw thread of allen key subassembly and connecting piece revolves to the opposite direction with the ratchet.
As a further optimization of the utility model, the length of the internal recess of hexagonal prism cover is less than the length of the cover body itself, prevents to lead to droing because of surpassing the maximum length of recess between the hexagonal prism cover body.
As a further optimization of the utility model, the screw thread turning direction of the end cover and the wrench body is opposite to the ratchet wheel turning direction.
The utility model has the advantages that:
1. the adjustable nested hexagonal prism cover body of a plurality of each other of this spanner, applicable in the hexagon socket head cap screw of many specifications, the practicality is strong, conveniently carries, and simple structure, and is efficient.
2. The wrench can be used for a working face which is difficult to contact with a common wrench in a narrow space, and has a wide application range.
3. After the inner hexagonal assembly of the wrench is sleeved with a workpiece, the wrench is rotated clockwise to tighten the inner hexagonal bolt, the wrench is rotated anticlockwise, the inner hexagonal bolt is kept still, and the inner hexagonal assembly is reset under the action of the spring after the bolt is screwed. The operation is very simple.
