Description

Technical Field

[0001] The utility model relates to the technical field of wrenches, in particular to a torque wrench which is convenient for installing nuts. Background Art

[0002] A wrench is a commonly used installation and disassembly tool. It is a hand tool that uses the principle of leverage to twist bolts, screws, nuts and other threaded fastening bolts or nuts to open or socket the openings or holes of the hardware.

[0003] For example, the Chinese patent with publication number CN216030457U proposes a Bluetooth wrench with adjustable torque. The component can be connected to the sleeve through a ratchet wrench head to twist the bolt, and the motor can drive the screw to rotate during twisting, so that the moving rod extends to the outside of the fixed tube, increasing the length of the fixed tube, so that people can increase the force arm when twisting the bolt through the wrench, thereby increasing the torque for twisting the bolt or nut, so that the same person can provide different torques to tighten the bolt or nut, avoiding the situation where the bolt or nut cannot be tightened due to insufficient torque, and is easy to use through the limit groove The cooperation with the limit block can limit the moving distance of the moving rod to prevent the moving rod from separating from the fixed cylinder. The rubber sleeve can increase the insulation of the wrench handle, so that the wrench can lock the charged bolts or nuts. The anti-slip groove can increase the friction of the rubber sleeve, so that people can hold the fixed cylinder firmly. The support rod can provide support for the ratchet wrench head to prevent the moving rod from being deformed due to the excessively long force arm when twisting the bolt. However, in this solution, when the wrench faces a narrow space, it is not easy to complete the locking of the nut due to the fixed length of the fixed cylinder. For this reason, we propose a torque wrench that is convenient for nut installation. Utility Model Content

[0004] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a torque wrench that is convenient for nut installation, so as to solve the problems mentioned in the background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A torque wrench for facilitating nut installation comprises: a handle, a wrench head is fixedly mounted on one end of the handle, a fixing groove is provided on the bottom surface of the wrench head, a hexagonal bolt sleeve is fixedly mounted inside the fixing groove; and an extension component, the extension component is arranged on one side of the handle and is used to extend the handle.

[0007] By adopting the above technical solution and setting a hexagonal bolt sleeve, when in use, the nut is sleeved by the hexagonal bolt sleeve, and the nut is locked by turning the handle. When faced with a narrow space, the length of the handle can be extended by extending the component, which makes it convenient for workers to lock the nuts in the narrow space and improves practicality.

[0008] Preferably, the extension component includes: an extension groove, which is opened on the top surface of the handle, and movable grooves are respectively opened on both sides of the extension groove, and a rotating rod is fixedly installed inside the movable groove; a first extension handle, which is sleeved inside the extension groove, and a movable hole is opened on one side of the first extension handle, and the movable hole is movably sleeved on the outer wall surface of the rotating rod.

[0009] By adopting the above technical solution and setting the first extension handle, when it is necessary to lock the nut in a narrow space, the first extension handle is rotated to rotate the first extension handle out of the extension groove, thereby extending the overall length of the handle, making it easier for the staff to lock the nut in the narrow space.

[0011] By adopting the above technical solution and setting a fixing screw, when the length of the extended handle of the first extension handle is still not enough for use, the fixing screw is removed by rotating the fixing screw to cancel the restriction on the second extension handle. At this time, the staff takes out the second extension handle and inserts it at the front end of the first extension handle, and then fixes the second extension handle at the front end of the first extension handle by inserting the fixing screw into the threaded hole, thereby further extending the use length of the handle and improving the convenience of using the wrench in a narrow space.

[0013] By adopting the above technical solution, a limiting screw is set and inserted into the limiting hole, so that the first extension handle is limited inside the extension groove, avoiding the need for the staff to manually pinch the first extension handle when the extension handle is not needed, thereby improving practicality.

[0014] Preferably, anti-slip pads are fixedly installed on the left and right sides of the handle respectively.

[0015] By adopting the above technical solution and providing an anti-skid pad, the friction between the handle and the hand is increased through the anti-skid pad, thereby improving the stability of hand holding.

[0016] Preferably, a lighting groove is provided on one side of the wrench head, and a fill light is fixedly installed inside the lighting groove.

[0017] By adopting the above technical solution and setting a fill light, fill light operation can be performed in a narrow space, so as to avoid poor lighting in a narrow space and the inability to see the nut with the naked eye, which affects the use, and further improve the convenience of using the wrench in a narrow space.

[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] By providing a hexagonal bolt sleeve, when in use, the nut is sleeved by the hexagonal bolt sleeve, and the nut is locked by turning the handle. When it is necessary to lock the nut in a narrow space, the first extension handle is rotated to make the first extension handle rotate out of the extension groove, thereby extending the overall length of the handle, which is convenient for the staff to lock the nut in the narrow space. When the length of the extended handle of the first extension handle is still not enough for use, the fixed screw is removed by rotating the fixing screw to cancel the restriction on the second extension handle. At this time, the staff takes out the second extension handle and inserts it back at the front end of the first extension handle, and then fixes the second extension handle at the front end of the first extension handle by inserting the fixing screw into the threaded hole, thereby further extending the use length of the handle, and improving the convenience of using the wrench in a narrow space.

[0020] By setting a limit screw and inserting the limit screw into the limit hole, the first extension handle is limited inside the extension groove, avoiding the need for the staff to manually pinch the first extension handle when the extension handle is not needed, thereby improving practicality; by setting a fill light, fill light operation can be performed in a narrow space, avoiding poor light in a narrow space and inability to see the nut with the naked eye, affecting use, and further improving the convenience of using the wrench in a narrow space.
