Description

combination wrench

technical field

The utility model relates to the field of mechanical tools, in particular to a combined wrench.

Background technique

A wrench is a commonly used installation and removal tool. Hand tools for turning bolts, screws, nuts, and other open or socketed fasteners whose threads hold bolts or nuts tightly by the principle of leverage. The wrench is usually formed with an opening or a sleeve hole for clamping a bolt or a nut at one or both ends of the handle. When in use, an external force is applied to the handle along the thread rotation direction to twist the bolt or nut.

When disassembling or assembling bolts, it is usually necessary to use a wrench to fix the nuts or bolts, and then use another wrench to twist the bolts or nuts to complete. When the operating space of mechanical parts is small, workers’ hands cannot pass through. Do not use a wrench to fix the other end of the bolt, which makes it inconvenient to disassemble and assemble the bolt.

Utility model content

Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the utility model is: how to provide a combination wrench which can conveniently fix the other end of the bolt and facilitate the disassembly of the bolt.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A combination wrench, characterized in that it includes a "C"-shaped wrench frame as a whole, one end of the wrench frame is fixed with a sleeve positioning rod set towards the other end, and the end of the sleeve positioning rod is detachably A positioning sleeve is installed; the other end of the wrench frame has a guide hole coaxially arranged with the sleeve positioning rod, and a wrench rod is movably worn in the guide hole, and the wrench rod faces the A ratchet sleeve matched with the positioning sleeve is detachably mounted on one end of the sleeve positioning rod, and one end of the wrench rod outside the wrench holder is bent into an L shape.

With the above structure, the worker can hold the wrench holder, fit the positioning sleeve on the bolt to be disassembled from the gap of the machine, and then move the wrench rod along the axial and circumferential directions of the guide hole, so that the ratchet sleeve is set on the bolt that needs to be disassembled. On the other end of the bolt, in this way, the bolt can be easily and quickly disassembled.

As an optimization, the wrench frame includes a guide hole connecting rod, a first right-angle connecting rod, a straight connecting arm, a second right-angle connecting rod and a positioning rod connecting block that are detachably connected in sequence, and the guide hole is arranged on the guide On the connecting rod of the hole, the sleeve positioning rod is fixedly arranged on the connecting block of the positioning rod.

With the above structure, the wrench holder can be disassembled and assembled, which is convenient for storing and taking the wrench, and is easy to carry.

As an optimization, the connecting rod for the guide hole also has a first connecting hole that is offset from the guide hole, the axis of the first connecting hole is 90 degrees to the axis of the guide hole, and the first right angle One end of the connecting rod is axially movably mounted on the first connecting hole; each of the two ends of the straight connecting arm has a positioning hole for inserting the first right-angle connecting rod and the second right-angle connecting rod respectively, The first right-angled connecting rod and the second right-angled connecting rod are respectively inserted into the positioning holes; the positioning rod connecting block also has a second connecting hole set in a misplaced position with the sleeve positioning rod. The axis of the second connecting hole is 90 degrees to the axis of the sleeve positioning rod, and one end of the second right-angled connecting rod is axially movably mounted on the second connecting hole.

Since the first right-angle connecting rod can be axially moved through the first connecting hole, and the second right-angle connecting rod can be axially moved through the second connecting hole, so that the distance between the straight connecting arm and the bolt to be disassembled can be The adjustment can be applied to devices with different space sizes, and the application range is wide.

As an optimization, the first right-angle connecting rod and the second right-angle connecting rod are all hexagonal wrenches, and the first connecting hole, the second connecting hole and the positioning hole are all hexagonal holes.

With the above structure, since the inner hexagonal wrench is mostly set in an L-shaped structure, using the inner hexagonal wrench as the first right-angle connecting rod and the second right-angled connecting rod can reduce the parts of the combined wrench. At the same time, after the combined wrench is disassembled, the inner The hex wrench can also be used alone, which can increase the applicability of this combination wrench.

In summary, the utility model has the advantages of being able to fix the other end of the bolt conveniently, facilitate the disassembly of the bolt, be applicable to equipment with different spaces, and have a wide application range.

Fig. 1 is a schematic structural view of an embodiment of the utility model.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail.

During specific implementation: as shown in Figure 1, a combination wrench includes a "C"-shaped wrench frame 1 as a whole, one end of the wrench frame 1 is fixed with a sleeve positioning rod 2 set towards the other end, the sleeve The end of the cylinder positioning rod 2 is detachably installed with a positioning sleeve 3; the other end of the wrench holder 1 has a guide hole coaxially arranged with the sleeve positioning rod 2, and the guide hole is movable A wrench lever 4 is installed, and one end of the wrench lever 4 towards the sleeve positioning lever 2 is detachably installed with a ratchet sleeve 5 matched with the positioning sleeve 3, and the wrench lever 4 is located on the One end outside the wrench holder 1 is bent into an L shape.

With the above structure, the worker can hold the wrench holder, fit the positioning sleeve on the bolt to be disassembled from the gap of the machine, and then move the wrench rod along the axial and circumferential directions of the guide hole, so that the ratchet sleeve is set on the bolt that needs to be disassembled. On the other end of the bolt, in this way, the bolt can be easily and quickly disassembled.

During implementation, the wrench frame 1 includes a guide hole connecting rod 11, a first right-angle connecting rod 12, a straight connecting arm 13, a second right-angle connecting rod 14 and a positioning rod connecting block 15 that are detachably connected in sequence. The hole is arranged on the connecting rod 11 of the guide hole, and the sleeve positioning rod 2 is fixedly arranged on the connecting block 15 of the positioning rod.

With the above structure, the wrench holder can be disassembled and assembled, which is convenient for storing and taking the wrench, and is easy to carry.

During implementation, the guide hole connecting rod 11 also has a first connection hole that is set in a misplaced position with the guide hole, the axis of the first connection hole is 90 degrees to the axis of the guide hole, and the first connection hole One end of the right-angle connecting rod 12 can be axially moved through the first connecting hole; The positioning hole installed, the first right-angle connecting rod 12 and the second right-angle connecting rod 14 are respectively inserted in the positioning hole; the positioning rod connecting block 15 also has a The second connection hole is provided, the axis of the second connection hole is 90 degrees to the axis of the sleeve positioning rod 2, and one end of the second right angle connection rod 14 can be axially moved through the second connection hole.

Since the first right-angle connecting rod can be axially moved through the first connecting hole, and the second right-angle connecting rod can be axially moved through the second connecting hole, so that the distance between the straight connecting arm and the bolt to be disassembled can be The adjustment can be applied to devices with different space sizes, and the application range is wide.
