[0031] The support mechanism 2 includes an extension assembly 21 and a drive assembly 22, and the drive assembly 22 is arranged on one side of the extension assembly 21;

[0032] The extension assembly 21 includes four lead screws 211. The four lead screws 211 are respectively rotatably connected to the inside of the base body 1. One end of each lead screw 211 is fixedly connected with a bevel gear 212. The surface of the bevel gear 212 is meshed with a bevel gear ring 213. The bottom end of the bevel gear ring 213 is rotatably connected to the inside of the base body 1. A cross bar 214 is threadedly connected to the surface of the bevel gear 212. Two ends of one side of the cross bar 214 are respectively fixedly connected with a limiting rod 215. One end of the limiting rod 215 is fixedly connected with a T-shaped rod 216. One bottom end of one side of the T-shaped rod 216 is fixedly connected with a support bar 217. One end of the support bar 217 is fixedly connected with the bottom end of one side of the T-shaped rod 216. Guide grooves are respectively opened at four ends inside the base body 1. The surface of the cross bar 214 is slidably connected to the inside of the guide grooves. A limiting hole is opened inside the base body 1. The surface of the limiting rod 215 is slidably connected to the inside of the limiting hole.

[0033] Further, the driving assembly 22 includes a support plate 221. The support plate 221 is fixedly connected to the front surface of the base body 1. A motor pole 222 is fixedly connected to the top of the support plate 221. A driving wheel 223 is fixedly connected to the bottom end of the motor pole 222. There are two driving wheels 223. The surfaces of the two driving wheels 223 are respectively drivingly connected with a transmission belt 224. A T-shaped plate 225 is fixedly connected to the inside of the driving wheel 223 at the back end. The surface of the T-shaped plate 225 is fixedly connected to the inside of the bevel gear ring 213.

Furthermore, when driving the bottom wheels 33 to move, the bottom wheels 33 support the ground, thereby improving the supporting stability of the base body 1, and further facilitating the machining operation of the base body 1 and the workpiece 4 on the workpiece.

[0034] Embodiment 2

[0035] Refer to Figures 1-6 , and on the basis of Embodiment 1, it is further obtained that the braking mechanism 3 includes a T-shaped wheel frame 31. The T-shaped wheel frame 31 is fixedly connected to the bottom end of the T-shaped rod 216. There are two T-shaped wheel frames 31. The top of the other T-shaped wheel frame 31 is fixedly connected to the bottom end of the cross bar 214. A wheel rod 32 is rotatably connected to the inside of the T-shaped wheel frame 31. A bottom wheel 33 is fixedly connected to the surface of the wheel rod 32. A positioning disc 34 is fixedly connected to one end of the wheel rod 32.

[0036] Further, a threaded hole is formed in the inside of one side of the T-shaped wheel frame 31. The surface of the bolt 35 is threadedly connected to the inside of the threaded hole. A positioning hole is formed in the surface of the positioning disc 34. The surface of the bolt 35 is matched with the inside of the positioning hole. The bolt 35 can be inserted into the inside of the positioning disc 34, and then one end of the bolt 35 passes through the inside of the T-shaped wheel frame 31 and corresponding threading and tightening operations are performed. Thus, after the stable movement adjustment of the base body 1, the supporting stability of the base body 1 can be further enhanced.

[0037] During the actual operation process, when this device is in use and the equipment is being used, the motor pole 222 drives the driving wheel 223 to rotate. Then, when the T-shaped plate 225 rotates, it drives the bevel gear ring 213 to rotate. Accordingly, when the bevel gear 212 rotates, it drives the lead screw 211 to rotate and drives the cross bar 214 to move. During this process, the cross bar 214 drives all the T-shaped rods 216 on the base body 1 to move outwards by means of the supporting connection of the limiting rod 215 and the supporting bar 217. Further, when the bottom wheel 33 moves, it supports the ground, thereby improving the supporting stability of the base body 1 and facilitating the processing operation of the base body 1 and the workpiece 4 on the workpiece.

[0038] After the movement of the bottom wheel 33 is completed, the bolt 35 can be inserted into the positioning disk 34 at this time. Then, one end of the bolt 35 passes through the T-shaped wheel frame 31 and corresponding thread tightening operations are carried out. Thus, after the stable movement adjustment of the base body 1, the supporting stability of the base body 1 can be further enhanced.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the said element.
