Two electro-hydraulic push rods 11 are fixedly installed on the front and rear sides of the inner cavity of the first cavity, and the two electro-hydraulic push rods 11 are arranged left and right. The power ends of two horizontally adjacent electro-hydraulic push rods 11 are fixedly connected to the same moving plate 9. The bottom ends of several rotating shafts 6 pass through the adjacent rectangular slots and second cavities respectively, and are rotatably connected to the top of the moving plate 9. Each rotating shaft 6 has a worm gear 7 fixedly fitted onto its outer wall. Several worm gears 7 that are laterally adjacent are meshed with the same worm 8. The top of each of the two moving plates 9 is fixedly connected to a fixed plate near the left and right sides, and a first bearing is fixedly connected to the fixed plate. The top of each of the two moving plates 9 is fixedly installed with a drive motor 10 near the left side. The right ends of the two worms 8 are respectively inserted into the inner cavity of the adjacent first bearing, and the left ends of the two worms 8 respectively pass through the inner cavity of the adjacent first bearing and are fixedly connected to the power output end of the adjacent drive motor 10. The top of the platform 1 is fixedly connected to a support plate 12 near the right side, and a horizontal plate 13 is fixedly connected to the top of the support plate 12. A hydraulic rod 14 is fixedly installed at the bottom of the horizontal plate 13 near the left side, and a lifting chamber 15 is fixedly connected to the power end of the hydraulic rod 14. The circular saw body 16 is fixedly installed in the inner cavity of the lifting chamber 15. A distance control mechanism is provided on the right side of the circular saw body 16, and a support mechanism is provided at the bottom of the circular saw body 16.

[0029] The distance control mechanism includes a distance plate 28, which is located on the right side of the platform 1. A threaded sleeve 29 is fixedly connected to the top of the distance plate 28, and a threaded rod 30 is screwed into the inner cavity of the threaded sleeve 29. Two fixed plates are fixedly connected to the bottom of the horizontal plate 13, and the two fixed plates are arranged left and right. A second bearing is fixedly connected to the fixed plate on the right side. The left end of the threaded rod 30 is rotatably connected to the adjacent fixed plate, and the right end of the threaded rod 30 passes through the inner cavity of the second bearing and is fixedly connected to a hand crank 31. A pressure sensor 34 is fixedly installed on the left side of the distance plate 28 near the bottom. A controller 35 is fixedly installed on the bottom of the platform 1 near the left side. A sliding plate 32 is fixedly connected to the top of the threaded sleeve 29, and the other side of the sliding plate 32 extends to the front side of the horizontal plate 13 and fits against the front side wall of the horizontal plate 13. A scale line 33 is provided at the top front side of the horizontal plate 13, which can precisely control the cutting length of the metal rod.

[0030] Working Principle: In use, the operator places a metal rod into the conveying trough 3 between two sets of rollers 4. By activating the electro-hydraulic actuator 11, two moving plates 9 are pushed relative to each other, causing the outer walls of the front and rear rows of rubber sleeves 5 to adhere to the metal rod, thus clamping and fixing it. Next, when two drive motors 10 are activated via an external power source, they rotate adjacent worm gears 8. The rotation of the worm gears 8 drives several adjacent worm wheels 7, which in turn rotate the rotating shaft 6. The rotating shaft 6 then rotates the rollers 4, which in turn rotate the rubber sleeves 5. Through the clockwise rotation of the front rubber sleeve 5 and the counterclockwise rotation of the rear rubber sleeve 5, combined with the external thread, the metal rod can be moved towards the side closer to the circular saw body 16. During the conveying process, when the right end of the metal rod comes into contact with the pressure sensor 34, the pressure sensor 34 sends a signal to the controller 35. The controller 35 temporarily shuts down the two drive motors 10. Subsequently, the hydraulic rod 14 is activated to push the lifting chamber 15 downward and bring the circular saw body 16 close to the metal rod. The circular saw body 16 can then be started by an external power supply to cut the metal rod. When it is necessary to adjust the cutting length of the metal rod, the hand crank 31 can be turned to rotate the threaded rod 30. The rotation of the threaded rod 30 causes the threaded sleeve 29 to move horizontally. The horizontal movement of the threaded sleeve 29 causes the spacer plate 28 to move synchronously. The cutting length of the metal rod can be adjusted by adjusting the horizontal distance between the spacer plate 28 and the table 1.

[0031] Example 2:

[0032] The support mechanism includes a support plate 18, which is located on the right side of the platform 1. The top of the support plate 18 is on the same horizontal plane as the bottom of the inner cavity of the conveying trough 3. A movable shaft 20 is fixedly fixed through the support plate 18 near the left side. Two connecting plates 19 are fixedly connected to the right side of the platform 1, and a third bearing is fixedly connected to the connecting plate 19. The front and rear ends of the movable shaft 20 are respectively inserted into the inner cavity of the adjacent third bearing. Rotating gears 21 are sleeved and fixedly attached to the outer wall of the movable shaft 20 near the front and rear ends. A movable rack 17 is meshed on the top of the rotating gear 21. Push plates 22 are fixedly connected to the left side of the two movable racks 17. Two electric telescopic rods 23 are fixedly installed at the bottom of the inner cavity of the conveying trough 3 near the right side. The power end of the electric telescopic rod 23 is fixedly connected to the left side wall of the adjacent push plate 22.

[0033] Mounting plates 24 are bolted to the right side of both support legs 2 located on the right side, and the same load-bearing plate 25 is fixedly connected to the right side of both mounting plates 24.

The two first limiting strips are slidably connected to the inner cavity of the adjacent first sliding grooves. A finished product collection box 27 is attached to the right side of the debris collection box 26, and a second handle is welded to the right side of the finished product collection box 27.

Two front and rear second sliding grooves are opened on the top of the load-bearing plate 25 near the right side, and the second sliding grooves are open. The two second limiting strips are slidably connected to the inner cavity of the adjacent second sliding grooves.

[0034] Working principle: When in use, the pallet 18 provides horizontal support to the right end of the metal bar during the cutting process of the circular saw body 16, thus preventing pressure from the circular saw body 16 from affecting the flatness of the cut. The chip collection box 26 collects the chips that fall during the cutting process. After the cutting is completed, the two electric telescopic rods 23 can be activated to push the two push plates 22 to the right, which in turn moves the moving rack 17 to the right. The moving rack 17 rotates the rotating gear 21, which in turn rotates the movable shaft 20, causing the right side of the pallet 18 to flip downwards, so that the cut product can be poured into the inner cavity of the finished product collection box 27.
