[0025] Working principle:

[0026] Working stage

[0027] After turning on the main power switch, the engine drives the pulley 7 on the crankshaft 8 to rotate when working. The pulley 7 drives the tensioner 5 to rotate continuously through the timing belt 2. The distance between the tensioner 5 and the guide wheel 6 limits the movement of the timing belt 2, making the timing belt 2 more stable during operation. The outer wall of the timing belt 2 will also have a cleaning effect on the rubber wheel 301 inside the connecting strip 302. At the same time, the timing belt 2 drives the cam 403 on the lug shaft 402 to rotate. The cam 403 will pull the valve 404 up and down at 306 degrees, so that the valve 404 drives the lower piston 9 to move synchronously. At the same time, the crankshaft drives the upper piston 9 of the outer wall to move, so that the inside of the piston 9 is in a moving state, thereby achieving the working effect.

[0028] Adjustment phase

[0029] By controlling the fixing rod 306 on the collar 307 to penetrate into the connecting hole 305 on the surface of the connecting belt 304, the connecting belt 304 drives the connecting strip 302 and the rubber wheel 301 on the connecting block 303 to pull the timing belt 2, so as to control the tightness between the timing belt 2 and the pulley 7, the timing wheel 401 and the guide wheel, and the rubber wheel 301 cleans the foreign matter on the surface of the timing belt 2, so as to reduce the friction between the timing belt 2 and the contact parts and increase the service life of the timing belt 2.
