Description

Adapter suitable for narrow space

Technical Field

The invention belongs to the technical field of accessories of wrenches, and particularly relates to an adapter suitable for a narrow space.

Background

The inner hexagonal wrench is a common mounting and dismounting tool, and is a manual tool for screwing a screw by utilizing the lever principle. However, the hexagon socket wrench is required to have a certain moving space and limited by the layout space, the space where a plurality of screws are installed is narrow, and the arms and even fingers of a person cannot extend into the space, so that the installation and the disassembly of the screws are greatly limited. Therefore, the adapter applicable to the narrow space is provided.

Disclosure of Invention

The invention provides an adapter suitable for a narrow space, and aims to enable an inner hexagon screw to be conveniently mounted and dismounted in the narrow space.

In order to achieve the purpose, the invention adopts the technical scheme that:

an adapter applicable to a narrow space comprises a screw sleeve and a screwdriver sleeve, wherein the screw sleeve is connected with the screwdriver sleeve in a welding mode, and the center of the screw sleeve is of a hollow structure matched with a nut of an inner hexagon screw;

the adapter is embedded with the socket head cap screw in the screw sleeve, the pin shaft of the ratchet wrench is embedded into the screwdriver sleeve, and the ratchet wrench is twisted to fix or loosen the socket head cap screw by the pin shaft of the ratchet wrench.

Furthermore, a connecting rod is arranged between the screwdriver sleeve and the ratchet wrench.

Further, the adapter is made of stainless steel.

Compared with the prior art, the invention has the following beneficial effects:

the inner hexagon screw adapter is arranged between the ratchet wrench and the inner hexagon screw and comprises a screw sleeve and a screwdriver sleeve which are welded together, the center of the screw sleeve is of a hollow structure and is matched with a nut of the inner hexagon screw and used for fixing the inner hexagon screw, the screwdriver sleeve is used for being connected with the ratchet wrench, a pin shaft of the ratchet wrench is embedded into the screwdriver sleeve and is in contact with the inner hexagon screw, and the screw can be installed and disassembled by rotating the ratchet wrench. The adapter occupies a small space, and the screws are ensured to be installed and detached in the minimum space. A connecting rod can be added between the socket head cap screw adapter and the ratchet wrench, so that the device can be used for mounting and dismounting the socket head cap screw in a slender and narrow space through torque transmission. This adapter collocation ratchet spanner is practical, is applied to in most mechanical device, and simple structure does not occupy the extra space, has solved the installation of screw and has dismantled the problem that snatchs the difficulty in narrow and small space, and the range of application is wide, and the commonality is strong, and convenient operation has improved work efficiency greatly.

The screw sleeve is made by stainless steel material, has certain elasticity for the nut of centre gripping hexagon socket head cap screw to guaranteed when installation and dismantlement screw in narrow and small space, can the set screw, avoided because of dropping the risk that is not convenient for pick up in narrow and small space.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, 3 and 4, the present invention provides an adapter suitable for a narrow space, which includes a screw sleeve 2 and a driver sleeve 3, wherein the screw sleeve 2 and the driver sleeve 3 are connected by welding, and the center of the screw sleeve 2 is a hollow structure adapted to the nut of the socket head cap screw 4. The screw sleeve 2 is made of stainless steel materials, has good elasticity, and can enable the socket head cap screws to be clamped in the screw sleeve 2 all the time.

As shown in fig. 2, when the wrench is used, the socket head cap screw 4 is embedded into the screw sleeve 2, the socket head cap screw 4 is fixed, the pin shaft of the ratchet wrench is embedded into the screwdriver sleeve 3, the pin shaft is enabled to abut against the socket head cap screw, the handle of the ratchet wrench is rotated, the adapter 1 is used as a fulcrum, and the screw can be installed and detached in a narrow space through the transmission of torque. Simultaneously, in darker narrow and small space, be connected through adding the connecting rod between adapter 1 and ratchet spanner, rotatory ratchet spanner makes the moment of torsion pass through the connecting rod transmission, just enables the screw and installs and dismantle in darker narrow and small space.

The preferred embodiments of the invention disclosed above are intended to be illustrative only. The preferred embodiments are not intended to be exhaustive or to limit the invention to the precise embodiments disclosed. Obviously, many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and the practical application, to thereby enable others skilled in the art to best utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
