One side of the base 201 is fixedly connected with a convex shell 202. A motor 203 is fixedly installed on one side of the convex shell 202. Both transmission shafts 207 are drivingly connected to the output shaft of the motor 203 through the main shaft 206, and the convex shell 202 can support the motor 203;

[0025] A worm 204 is rotatably connected inside the convex shell 202. One end of the worm 204 is connected to the output shaft of the motor 203. The worm 204 is meshed with a worm gear 205, and the worm gear 205 is fixedly connected to one end of the transmission shaft 207.

[0026] On both sides of the main shaft 206, a first helical gear 208 is fixedly provided. In the middle of both transmission shafts 207, a second helical gear 209 is fixedly provided. The two second helical gears 209 are respectively meshed with the two first helical gears 208. On both sides of both transmission shafts 207, a third helical gear 2010 is fixedly provided. The main shaft 206 can drive the two transmission shafts 207 to rotate through the first helical gear 208 and the second helical gear 209;

[0027] On both sides of the bottom end of the base 201, two telescopic openings 2014 are provided. At the four corners of the bottom end of the base 201, ground wheels 2013 are installed. A first cover plate 2011 is installed on the surface of the base 201, and a second cover plate 2012 is installed on the surface of the convex shell 202. The first cover plate 2011 and the second cover plate 2012 can play a protective function, and the base 201 can be moved through the ground wheels 2013.

[0028] Embodiment 2:

[0029] All four support components 3 include driven shafts 301. All four driven shafts 301 are rotatably connected to the inside of the base 201. The four driven shafts 301 are respectively drivingly connected to the two transmission shafts 207. At the top ends of the four driven shafts 301, a sliding table 303 is connected through a lead screw 308. On one side of each of the four sliding tables 303, a support leg 305 is fixedly provided;

[0030] At the bottom of all four driven shafts 301, a fourth helical gear 302 is fixedly provided. The four fourth helical gears 302 are respectively meshed with the four third helical gears 2010. The third helical gear 2010 can drive the driven shaft 301 to rotate through the fourth helical gear 302;

[0031] The bottom ends of the four lead screws 308 are respectively fixedly connected to the bottom ends of the four driven shafts 301. The top ends of the four lead screws 308 are all rotatably connected to the inner wall of the top end of the base 201. Threaded holes 304 are formed in the middle of the four sliding tables 303, and the four threaded holes 304 are respectively threadedly connected to the four lead screws 308. The thread directions of two of the four lead screws 308 are opposite to those of the other two lead screws 308, which can offset the inconsistent rotation directions of the lead screws 308 caused by the bevel gear three 2010, and can make the support legs 305 lift synchronously.

[0032] One side of each of the four support legs 305 is fixedly provided with a guide block 306. Each of the four guide blocks 306 is slidably connected to a guide rail 307. One side of the four guide rails 307 is respectively fixedly connected to the inner walls on both sides of the base 201. The four support legs 305 are respectively slidably connected to the four telescopic openings 2014. The guide rails 307 and the guide blocks 306 can guide the support legs 305, and can ensure the vertical movement of the support legs 305.

[0033] During use, the base 201 can support the bottom end of the laser cutting machine body 1. When it is necessary to move the laser cutting machine body 1, the staff first drives the worm 204 through the motor 203. The worm 204 drives the main shaft 206 to rotate through the worm gear 205. The main shaft 206 drives the two transmission shafts 207 to rotate through the bevel gear one 208 and the bevel gear two 209. The two transmission shafts 207 drive the four driven shafts 301 to rotate simultaneously through the bevel gear three 2010 and the bevel gear four 302. The lead screws 308 rotate with the driven shafts 301. Through the threaded holes 304, the rotational movement can be converted into the linear movement of the sliding tables 303. Since the thread directions of two of the four lead screws 308 are opposite to those of the other two lead screws 308, the inconsistent rotation directions of the lead screws 308 caused by the bevel gear three 2010 can be offset, and the four lead screws 308 can drive the four support legs 305 to rise synchronously. After the bottom ends of the support legs 305 are suspended, the four ground wheels 2013 can land, and then the laser cutting machine body 1 can be moved through the four ground wheels 2013. After moving to the designated location, the staff reversely drives the worm 204 through the motor 203. After the bottom ends of the support legs 305 land, the ground wheels 2013 can be suspended. During this process, the exposed length of the support legs 305 can be adjusted, and then the height of the laser cutting machine body 1 can be adjusted, which is convenient for staff of different heights to operate.
