Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic tools, in particular to a universal socket for a pneumatic wrench. Background Art

[0002] A pneumatic wrench is a hand-held tool that uses compressed air as a power source. It converts the energy of compressed air into rotational torque through the movement of an internal piston or turbine, so as to quickly tighten or loosen fasteners such as bolts and nuts. The pneumatic wrench has the characteristics of high rotational speed and large torque, and is widely used in industrial occasions such as automobile maintenance, machinery manufacturing, and assembly lines, which can significantly improve work efficiency and reduce the labor intensity of workers. Compared with an electric wrench, a pneumatic wrench is usually smaller in volume, lighter in weight, and does not have the problem of battery life, but it needs to rely on a stable compressed air supply system.

[0003] In the existing pneumatic wrench socket technology, there is generally a design limitation, that is, the socket can only adapt to the bolt disassembly and assembly operations in a single direction. This design often causes the inability to smoothly tighten or remove bolts when there are obstacles at the outlet of the bolt or the space is limited. Due to this unidirectional operation of the pneumatic wrench socket, in narrow or complex environments, such as inside the automobile engine compartment and machinery equipment maintenance, etc., workers encounter great inconvenience when performing bolt operations, which not only reduces work efficiency, but also may increase the operation difficulty and safety risks. Summary of the Utility Model

[0004] An object of the utility model is to provide a universal socket for a pneumatic wrench, so as to solve the problems that due to this unidirectional operation of the pneumatic wrench socket, in narrow or complex environments, such as inside the automobile engine compartment and machinery equipment maintenance, etc., workers encounter great inconvenience when performing bolt operations, which not only reduces work efficiency, but also may increase the operation difficulty and safety risks as mentioned in the above background.

[0005] A universal socket for a pneumatic wrench according to an embodiment of the utility model includes a pneumatic wrench body and a rotating head. One end of the pneumatic wrench body is provided with an output end, and the output end is drivingly connected with the rotating head. The outer end of the rotating head is snap-fitted inside a first socket connecting piece. One end of the first socket connecting piece away from the rotating head is fixedly connected with a fixing rod. One end of the fixing rod away from the first socket connecting piece is fixedly connected with a sphere. The sphere is installed at one end inside a second socket connecting piece. The sphere and the second socket connecting piece are connected by a spherical joint. The outer end of the second socket connecting piece is provided with a socket body, and a multi-angle groove is formed inside the socket body.

[0006] Preferably, the socket body is threadedly connected inside the second socket connecting piece.

[0007] Preferably, the rotating head is drivingly connected inside the output end through a mounting structure.

[0008] Preferably, grooves are formed on both side surfaces of the rotating head, and clamping blocks are slidably connected inside the grooves.

[0009] Preferably, a spring structure is provided between the inner surface of the clamping block and the inner wall of the groove.

[0010] Preferably, a card slot is formed through the surface of the first sleeve connector.

[0011] Preferably, a changeover switch is installed at the upper end of one side of the pneumatic wrench body.

[0012] Preferably, a control switch is installed at the lower end of one side of the pneumatic wrench body.

[0013] The beneficial effects of the present utility model are as follows:

[0014] Through structures such as the sphere and the second sleeve connector provided in the present utility model, when it is necessary to tighten or disassemble a bolt with other parts blocking the end, according to the shape of the nut at the bolt end, a suitable sleeve body is replaced, and the sleeve body is threadedly connected into the second sleeve connector. Subsequently, the rotating head can be driven to rotate by the pneumatic wrench body, thereby driving the first sleeve connector to rotate, and the sphere can rotate freely inside the second sleeve connector, so that different angles are formed between the second sleeve connector and the first sleeve connector to adapt to complex environments. Moreover, as the first sleeve connector rotates, the sphere, the second sleeve connector, and the sleeve body also rotate accordingly, achieving the purpose of tightening or disassembling bolts in complex environments, greatly improving the flexibility and convenience of operation, significantly enhancing the work efficiency and reducing the safety risk, and effectively avoiding the problem that due to the one-way operation of the pneumatic wrench sleeve, in narrow or complex environments, such as inside an automobile engine compartment, machinery equipment maintenance, etc., workers encounter great inconvenience when performing bolt operations, which not only reduces the work efficiency but also may increase the operation difficulty and safety risk;

[0015] Through structures such as the clamping blocks and clamping grooves provided in the present utility model, in the traditional way, the sleeve body is directly sleeved on the end of the rotating head at the output end of the pneumatic wrench for use, which easily leads to the loss of the sleeve. When installing the present utility model, the first sleeve connecting piece is sleeved on the end of the rotating head. The clamping blocks are ejected by the spring structure inside the groove and clamped inside the clamping groove, realizing the clamping connection between the first sleeve connecting piece and the rotating head. When disassembling, manually press the two clamping blocks at both ends into the groove, and the first sleeve connecting piece can be directly pulled out from the end of the rotating head, realizing the stable connection and convenient disassembly between the sleeve and the rotating head of the pneumatic wrench, effectively preventing the accidental detachment of the sleeve during use.
