[0015] The technical solution of the present invention will be further described below with reference to the accompanying drawings and implementation examples.
[0016] 1-4 , the device comprises an arc-shaped cavity (1), a pipe (2), a short cavity (3), a switching valve (4), a connecting rod (5), a guide rail (6), a fixed body (7), a fixed frame (8), a fluid inlet (9), a feedback rod (10), a small piston body (11), a main piston (12), and a feedback valve (13).
[0017] During use, pressurized fluid enters the fluid inlet 9 and flows through the pipe 2 into the hole on the side of the fixed frame 8 in two ways, flowing to the switching valve 4. The hole on one side of the fixed frame 8 is also connected to the pipe 2 to the feedback valve 13. The fluid flows through the feedback valve 13 and pushes the small piston body 11 in the short chamber 3. At this time, the connecting rod 5 on one side pulls the switching valve 4, closing one side of the switching valve 4 and releasing pressure on the other side. The fluid passes through the switching valve 4 on one side into the arc chamber 1, pushing the main piston 12 in an arc motion, pushing the guide rail 6 and the fixed body 7. The fixed body 7 pushes the feedback rod 10, causing the feedback valve 13 to switch. At the same time, the direction of fluid inflow changes, causing the small piston body 11 in the short chamber 3 on one side to push the connecting rod 5 to change the closure and pressure relief of the switching valves 4 on both sides, while the small piston body 11 in the short chamber on the other side releases pressure. Changing the input fluid pressure can change the arc reciprocating motion rate.

Any equivalent replacement or modification made by a person skilled in the art within the technical scope disclosed in the present invention and in accordance with the technical solution and inventive concept of the present invention shall be covered by the scope of protection of the present invention.
