Description

Multi-specification wrench

Technical Field

The utility model relates to a mechanical tool, more specifically relate to a spanner of many specifications.

Background

A wrench is a common installation and removal tool. Hand tools for turning bolts, screws, nuts and other threaded fasteners for tightening openings or trepanning of bolts or nuts using the principle of leverage.

Common wrenches are basically divided into a dead wrench and an adjustable wrench, the dead wrench is mostly a fixed wrench opening, only one nut can be adjusted, if the encountered nuts have multiple specifications, the dead wrench with the multiple specifications needs to be prepared, and the working efficiency is further reduced when the wrench is replaced for multiple times in the using process; the adjustable wrench has the advantages that the width of the opening can be adjusted within a certain size range, bolts or nuts of different specifications can be screwed, but the wrench is poor in fixity, the nuts can slide out of the wrench opening by carelessly exerting force during screwing, and the safety is poor. The two wrenches are linear wrenches, so that the problems of inconvenience in rotation, incapability of exerting force and the like can be caused when the wrenches are used in a narrow space, and the work efficiency is integrally reduced.

Therefore, a wrench integrating nuts with different specifications needs to be researched, so that the wrench is convenient to carry and use, and the working efficiency can be improved.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art, the utility model provides a spanner of many specifications is fit for the hexagon nut of multiple specification and uses, this spanner convenient to carry, and spanner handle length can be adjusted wantonly, and application range is wide, and work efficiency is high.

The utility model discloses a realize through following technical scheme:

a multi-specification wrench comprises a wrench handle and a wrench head which are arranged on the same straight line, wherein the wrench handle comprises a first wrench handle and a second wrench handle which are connected together through a bolt, a plurality of connecting holes are formed in the first wrench handle or the second wrench handle, and the size of each connecting hole is matched with the bolt; the handle head comprises a first handle head and a second handle head, the starting end of the first wrench handle is fixedly connected with the first handle head, the tail end of the second wrench handle is fixedly connected with the second handle head, a plurality of different wrench openings are formed in the first handle head, and another plurality of different wrench openings are formed in the second handle head.

Furthermore, a common large-caliber hexagon nut wrench opening is arranged on the first crown, and is respectively M12, M14, M16, M18 and M20; the second crown is provided with a common hexagonal nut wrench opening with a small diameter, which is respectively M4, M5, M6, M8 and M10.

Furthermore, the first wrench handle is of a hollow cylinder structure, the second wrench handle is of a solid cylinder, and the diameter of the hollow cavity of the first wrench handle is equal to that of the cylinder of the second wrench handle.

Further, the number of the connecting holes is two.

Furthermore, the first wrench handle and the second wrench handle are rotatably connected through bolts, and the rotating angle range is 0-360 degrees.

Furthermore, the wrench handle is sleeved with an anti-slip sleeve.

The utility model has the advantages that: the wrench of the utility model combines ten kinds of wrenches with common specifications together, which is suitable for hexagon nuts with different specifications; the first wrench handle is hinged with the second wrench handle, so that the first wrench handle and the second wrench handle can rotate freely, and the convenience in use and carrying is improved; in addition, the connecting holes arranged on the wrench handle are connected through bolts, the length of the wrench handle can be adjusted at will, the application range of the wrench is enlarged, the application space of the wrench is enlarged, and the working efficiency is further improved.

In the attached drawings, 1 handle head I, 2 wrench handle I, 3 wrench handle II, 4 handle head II, 5 bolts and 6 connecting holes.

Detailed Description

The attached drawing is a concrete embodiment of the utility model.

As shown in fig. 1-3, a multi-specification wrench comprises a wrench handle and a wrench head which are arranged on the same straight line, wherein the wrench handle comprises a first wrench handle 2 and a second wrench handle 3 which are connected together through a bolt 5, the first wrench handle 2 or the second wrench handle 3 is provided with a plurality of connecting holes 6, and the size of each connecting hole 6 is matched with the bolt 5; the crown comprises a crown first 1 and a crown second 4, the starting end of the wrench handle first 2 is fixedly connected with the crown first 1, the tail end of the wrench handle second 3 is fixedly connected with the

crown second

4, and 5 common large-caliber hexagon nut wrench openings are arranged on the crown first 1 and are respectively M12, M14, M16, M18 and M20; the second crown 4 is provided with 5 common hexagonal nut wrench mouths with small caliber, namely M4, M5, M6, M8 and M10.

Further, wrench handle 2 is cavity cylinder structure, and wrench handle two 3 is solid cylinder, and wrench handle 2's cavity diameter equals with wrench handle two 3's cylinder diameter, makes wrench handle two 3 can stretch into wrench handle 2's cavity just, and wrench handle and crown all adopt carbon element or alloy material's structural steel, and the firmness is strong, resistant use. The first wrench handle 2 and the second wrench handle 3 are rotatably connected through a bolt 5, and the rotating angle range is 0-360 degrees.

Further, the number of the connecting holes 6 is 3, the bolt 5 is fixedly installed in the connecting holes 6, the first wrench handle 2 is movably connected with the second wrench handle 3, the length of the second wrench handle 3 is adjusted by replacing the connecting holes 6 of the fixing bolt 5, and therefore the length of the whole wrench is adjusted, and convenience in use in narrow space is achieved.

Furthermore, the wrench handle is sleeved with the anti-slip sleeve, so that the phenomenon that the wrench slips when in use can be effectively prevented.
