When the rotating rod rotates, the threaded sleeve is threadedly connected to the surface of the rotating rod, and then the receiving rod is moved in the limiting block under the drive of the threaded sleeve, and the fixed rod provides support force for the rotation of the driven bevel gear. The receiving rod abuts the fixed block against the piston surface, thereby fixing it in the fixed plate, starting the first servo motor to drive the belt to rotate, thereby causing the rotating shaft to drive the cutting knife to rotate in the baffle, starting the second servo motor to drive the threaded rod to rotate, thereby driving the fixed plate and the receiving block to move toward the cutting knife at the same time.

[0004] However, this patent still has some shortcomings. When used, this patent mainly adopts one of the fixed plates with a positioning block and other structures to fix the piston rod, while the fixed plate at the other end only plays a supporting role. When the piston rod is too long or the piston rod is heavy, the piston rod is easily affected by gravity and deflected, resulting in skewed cutting. Therefore, a piston rod processing and cutting mechanism with a limiting function is proposed to solve the above problem. Utility Model Content

[0012] First, the present invention provides a bottom fixing platform, an adjustment fixing platform, and fasteners. When the piston rod is fixed, the bottom fixing platform and the adjustment fixing platform are locked by bolts and nuts. Then, the fastening screw is rotated, and the fastening screw drives the fastening plate to press the piston rod to complete the fixation. When the piston rod lengths are different and need to be adjusted, the user can rotate the moving button to change the position of the movable block, so that the bottom fixing platforms and the adjustment fixing platforms on both sides can provide stable support. This can provide more stable support during cutting and reduce the occurrence of cutting deflection due to cutting vibration or the piston rod's own gravity.

[0013] Secondly, the utility model provides a water collection tank, a water pump and a nozzle. When cutting is in progress, the water pump is turned on to draw water from the water collection tank through the pipe into the nozzle, thereby cooling the cutting blade and extending its service life.
