Then, two racks 5 are symmetrically arranged on the top of the support pads 3, and a gear 6 is meshed and connected to the back surfaces of the two racks 5. Then, at the center of the two gears 6, a gear 6 is meshed and connected to the back surfaces of the two racks 5. A rotating shaft 8 is fixedly penetrated at each position, and the two rotating shafts 8 are connected to the box frame 1 through a limit block, and then a worm wheel 7 is provided at one end of the two rotating shafts 8 and the end away from the gear 6, and a worm 9 is meshed and connected above the two worm wheels 7, and then a rotating rod 10 is commonly penetrated and connected at the central axis position of the two worm gears 9, and the two ends of the rotating rod 10 are limitedly connected to the box frame 1 through a connecting block, and one end of the rotating rod 10 is connected and movably penetrated through the connecting block and connected to a rotating crank 11, and the setting of Taikoo Oh 1 can adjust the rotation of the rotating rod 10;

[0022] When the device is in use, the rotating handle 11 is turned to adjust the rotating rod 10, and then the two worms 9 are driven to rotate through the rotating rod 10, and the worm 9 is meshed with the worm wheel 7 through the rotation adjustment, and then the rotating shaft 8 is rotated, and then the gear 6 is driven to rotate through the rotating shaft 8, and the rotating gear 6 is meshed with the rack 5, so that the rack 5 is moved downward, and the downward-moving rack 5 drives the support pad 3 and the rubber sheet 4 set at the bottom of the rack 5 to move downward, so that the support pad 3 and the rubber sheet 4 are in contact with the ground, so as to limit and fix the device for easy use. When it is necessary to move and transport the device, the rotating crank 11 is rotated in the opposite direction, so that the rack 5 drives the support pad 3 to move up and be stored in the storage chamber 2 again, so that the four steering wheels 18 are in contact with the ground, and then the entire device can be moved and transported by the four steering wheels 18;

[0023] As a further implementation of this embodiment, Figure 1-4 As shown, a saw body frame 16 is arranged in the box frame 1, and then two folding panels 17 are movably connected to the upper surface of the saw body frame 16 through hinges, and three lifting blocks 15 are evenly arranged on the left and right side walls of the saw body frame 16, and then two cross bars 12 are symmetrically arranged on the left and right sides of the box frame 1, and a threaded rod 13 is connected to the upper surface of the cross bar 12 for limited rotation, and then two guide rods 14 are symmetrically arranged on the upper surface of the cross bar 12 and on both sides of the threaded rod 13, and the guide rod 14 is movably passed through the surface of the lifting block 15, and the threaded rod 13 is threadedly passed through the surface of the lifting block 15, and at the same time, an adjusting button for rotating and adjusting the threaded rod 13 is connected to the top of the threaded rod 13;

[0024] When it is necessary to use the saw blade assembly in the saw body frame 16 to cut the plate, the threaded rod 13 can be adjusted and rotated by the adjusting knob, and then the lifting block 15 drives the saw body frame 16 to move up and out of the box frame 1 under the threaded drive of the threaded rod 13 and the guiding action of the guide rod 14. At the same time, the height of the saw body frame 16 can be adjusted according to the height of the staff. When not in use, the threaded rod 13 can be rotated in the opposite direction to adjust the saw body frame 16 so that the saw body frame 16 moves down and is stored in the box frame 1, and then the two folding panels 17 are flipped and closed to the top of the saw body frame 16;

[0025] Specific working principle:

[0026] When it is necessary to cut the plate through the device, the rotating rod 10 is adjusted by rotating the crank 11, and then the two worms 9 are driven to rotate by the rotating rod 10, and the meshing of the worm 9 and the worm wheel 7 is adjusted by rotation, so as to rotate the shaft 8, and then the gear 6 is driven to rotate by the shaft 8, and the meshing of the rotating gear 6 and the rack 5 is used to move the rack 5 downward, and the support pad 3 and the rubber sheet 4 arranged at the bottom of the rack 5 are driven downward by the downwardly moved rack 5, so that the support pad 3 and the rubber sheet 4 are in contact with the ground, so as to limit and fix the device, and then the rotating threaded rod 13 is adjusted by the adjusting knob, and then the lifting block 15 drives the saw body frame 16 to move up and out of the box frame 1 under the threaded drive of the threaded rod 13 and the guiding action of the guide rod 14. At the same time, the height of the saw body frame 16 can be adjusted according to the height requirements of the staff. When not in use, the adjusting threaded rod 13 can be rotated in the opposite direction to make the saw body frame 16 move down and be stored in the box frame 1, and then the two folding panels 17 can be flipped over and closed to be placed on the top of the saw body frame 16. When the device needs to be moved and transported, the rotating crank 11 is rotated in the opposite direction to make the rack 5 drive the support foot pad 3 to move up and be stored in the storage chamber 2 again, so that the four steering wheels 18 are in contact with the ground, and then the entire device can be moved and transported by the four steering wheels 18. The setting of this structure can quickly realize the lifting and lowering of the support foot pad 3, and then through the cooperation with the steering wheel 18, the fixed use and mobile transportation of the device can be quickly adjusted, thereby improving the practicality of the device.
