Description

Technical Field

[0001] The utility model relates to an impact wrench, in particular to the technical field of impact wrench supporting accessories. Background Art

[0002] Impact wrenches, due to their powerful impact force and high torque output, are suitable for applications requiring high-intensity work, such as heavy machinery maintenance and automotive repair. However, the weight of impact wrenches can cause fatigue to workers who use them for extended periods, reducing work efficiency and even causing them to slip due to insufficient grip, posing a safety hazard. Therefore, Chinese utility model patent CN202090000315.5 proposes adding a support member to the top of the impact wrench, allowing it to be hung from the user's work belt.

[0003] However, this only addresses the risk of the impact wrench falling to the ground, and does not solve the fatigue problem caused by holding the impact wrench for a long time. In addition, the support structure in the above-mentioned patent document generally adopts a design in which a bracket holds the lifting ring, which allows the lifting ring to fall in a certain direction. However, impact wrenches sometimes need to operate in corners and confined spaces, which further requires adjusting the hanging angle of the impact wrench. The current design is difficult to meet this requirement. Summary of the Invention

[0004] In order to solve the above problems, the utility model provides an impact wrench.

[0005] In order to achieve the above purpose, the technical solution of the utility model is:

[0006] An impact wrench comprising:

[0007] Motor;

[0008] a first housing in which the motor is installed;

[0009] Gearbox;

[0010] a second housing in which the gear box is installed, wherein the first housing is locked to the second housing via a locking member to form a housing body;

[0011] Suspension parts;

[0012] The bearing part comprises a bracket mounted on the shell body and a rotating bearing connected to the suspension member, wherein the rotating bearing has a first direction and a second direction orthogonal to each other, and the suspension member can be offset along the first direction and / or the second direction.

[0013] Furthermore, the bracket includes a base extending along the first direction and the second direction, and a first lifting lug provided on the base, and the rotating bearing member is rotatably connected to the first lifting lug.

[0014] Furthermore, the suspension member has a lifting ring and a second lifting lug, and the second lifting lug is rotatably connected to the rotary bearing member.

[0015] Furthermore, the bracket further includes feet, and the feet are locked to the housing body by locking members.

[0016] Furthermore, the rotary bearing member includes a cross shaft having a first direction and a second direction, and the cross shaft is mounted on the bracket through bearings.

[0017] Furthermore, the bearing is a ball bearing.

[0018] Even further, the bearing is a damping bearing.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] The present utility model suspends the impact wrench by connecting the suspension member through the bearing portion, avoiding the fatigue problem caused by the long-term operation of the impact wrench and improving the work efficiency. At the same time, a rotary bearing member with multiple angles is adopted to replace the commonly used bracket design in the prior art, enabling the impact wrench to change the angle of its body according to needs when suspended to adapt to complex working environments.
