[0002] A pneumatic wrench, also known as a ratchet wrench and electric tool combination, is mainly a tool that provides high torque output with minimal consumption. It uses a continuous power source to accelerate the rotation of an object with a certain mass, and then instantly hits the output shaft, thereby obtaining a relatively large torque output.

[0003] Existing pneumatic wrench fixing working devices have limitations in adapting to different usage scenarios. For example, the utility model with patent number CN216464317U, although this device can effectively fix the pneumatic wrench, its design does not take into account the need for angle adjustment in actual operation. When the staff needs to tighten or loosen the screws at different angles, this device cannot meet the needs. Since the practical angle cannot be adjusted, its scope of application is greatly limited. It is often necessary to adjust one's own position or the position of the workpiece in order to find a suitable operating angle, which not only increases the complexity of the work, but also reduces work efficiency.

A bottom plate 16 is provided at the bottom of the base 2, and a plurality of fixed blocks are sleeved on the bottom plate 16 on the outside of the threaded rod 11 and the sleeve 10. The threaded rod 11 is rotated to move it, thereby pushing the hydraulic oil inside the oil cylinder 12 into the sleeve 10, pushing the push blocks 15 symmetrically arranged inside the sleeve 10, so that they push the stop block 9, and finally drive the pull rod 8 to move, so that the stop block 14 fixed at the end of the pull rod 8 presses the angle plate 13 to limit its rotation, and finally the slide bar 3 stops at the desired angle.

[0024] Furthermore, a fixing plate 1 is sleeved on the end of the slide rod 3, and a plurality of fixing frames 6 are provided on the base 2 below the fixing plate 1. The fixing frames 6 fix the starting wrench and cooperate with the fixing frames 6 to tighten the bolts.

[0025] Furthermore, a piston is sleeved inside the end of the oil cylinder 12 close to the threaded rod 11, and the piston is fixed to the end of the threaded rod 11 away from the rocker 7. The threaded rod 11 pushes the piston to move, pushing the hydraulic oil inside the oil cylinder 12 into the sleeve 10.

[0026] Furthermore, the angle disc 13 is circular and cooperates with the stop block 14 to limit the slide bar 3 to a desired angle.

[0027] Furthermore, the bottom plate 16 is T-shaped, and cooperates with the T-shaped groove formed in the base 2 to protect the sleeve 10 , the pull rod 8 , the cylinder 12 and the threaded rod 11 .

[0028] Furthermore, a protruding portion is provided at one end of the fixing pin 4 to clamp the angle disc 13 to prevent the angle disc 13 from being separated from the fixing pin 4 .

[0030] Working principle: The device is mainly composed of a base 2, a slide bar 3, an angle plate 13, a fixed pin 4, a limit block 5, a stop block 14, a pull rod 8, a stop block 9, a push block 15, a sleeve 10, a cylinder 12, a threaded rod 11 and a rocker 7. During operation, first put the workpiece to be operated into the fixed frame 6, then put the starter wrench into the fixed plate 1 and fix it, then rotate the rocker 7 to drive the threaded rod 11 to rotate, and the thread on the threaded rod 11 and the thread in the fixed block 17 cooperate with each other to push the threaded rod 11 to move, so that the hydraulic oil inside the cylinder 12 is pushed between the sides of the push blocks 15 set in the sleeve 10 that are close to each other, and the push blocks 15 symmetrically set in the sleeve 10 are pushed to both sides, so that they push the stop block 9, and finally drive the pull rod 8 to move.

[0031] In order to improve stability and safety, a fixed plate 1 is sleeved on the end of the slide bar 3, and a plurality of fixed frames 6 are arranged on the base 2 below the fixed plate 1. The fixed plate 1 fixes the pneumatic wrench and cooperates with the fixed frame 6 to process the workpiece. It can ensure that the workpiece will not move or loosen during the processing. In the design of the oil cylinder 12, a piston is assembled inside one end of the oil cylinder 12 near the threaded rod 11, and the piston is fixed to the end of the threaded rod 11, and this end is far away from the rocker 7. When the threaded rod 11 rotates, it pushes the piston to move, and then pushes the hydraulic oil in the oil cylinder 12 to the sleeve 10. The angle disc 13 arranged on both sides of the base 2 is designed to be circular, and works with the stop block 14 to limit the movement of the slide bar 3 to a specific angle. The bottom plate 16 below the base 2 is designed to be T-shaped, which matches the corresponding T-shaped groove on the base 2, and can effectively protect the sleeve 10, the pull rod 8, the oil cylinder 12 and the threaded rod 11 from external influences. In order to prevent the angle disc 13 from accidentally falling out, a protruding part is provided at one end of the fixing pin 4 to ensure that the angle disc 13 is firmly locked in place. It not only ensures the stability of the machinery, but also improves the safety and accuracy of the operation.
