However, the following problems still exist:

[0003] During actual use, the water pump is energized to extract the hydraulic oil inside the hydraulic oil tank through the first water pipe, and the extracted hydraulic oil is transported to the inside of the fixed block through the second water pipe. The piston disc slides under pressure, driving the return spring to extend, causing the pull rod to move upward, pushing the slider to slide, and causing the slider to rotate, driving the guide rail to rotate, causing the guide rail to squeeze the timing chain, thereby adjusting the tension of the timing chain. However, the side of the chain rubs against the two sides of the body, which causes damage to the engine body, sealing cover or chain, further affecting the engine's intake and exhaust, making it inconvenient to use.

[0006] Preferably, the plurality of positioning holes are symmetrically distributed with the axis of the base plate as the center.

[0007] Preferably, the surface of the cover plate is fixedly connected to the main body through a plurality of the mounting holes.

[0008] Preferably, the first connection hole is located above the second connection hole, and the plurality of connection plates are symmetrically distributed around the axis of the shell.

[0009] Preferably, two ends of the hydraulic spring are fixedly connected to the inner wall of the housing and the surface of the push plate respectively.

[0010] Preferably, the interior of the hydraulic sleeve is filled with hydraulic oil, and the plurality of hydraulic sleeve bodies are symmetrically distributed with the axis of the housing as the center.

[0011] The beneficial effects of the utility model are:

[0012] By setting a sliding connection between the hydraulic slide rod and the surface of the shell, the hydraulic spring on the inner wall of the shell pushes the push plate at one end of the hydraulic slide rod to move inward, and the adjusting gear is rotationally connected to the surface of the push plate through the wheel axle.
