[0033] Specifically, there are motors 9 on the left and right sides of the workbench 1, and the rotation of the motor 9 drives the second threaded rod 3 to rotate, so that the first slider 4 moves and drives the first rotating shaft 5. The second rotating shaft 7 also rotates through the connecting rod 6, so that the connecting rod 6 gradually vertically lifts the support plate 11. Turning on two motors 9 at the same time can make the support plate 11 raised in parallel. If only one motor 9 is turned on, only one side of the support plate 11 will be lifted to achieve the purpose of adjusting the angle. The anti-slip pad 13 on the top of the support plate 11 and the L-shaped plates 12 at the four corners can effectively prevent the objects supported on the support plate 11 from slipping.

[0034] Reference Figure 1 and Figure 3The support mechanism 2 includes a hollow column 202, and a plurality of hollow columns 202 are respectively fixedly connected to the four corners of the bottom of the workbench 1. A rocker 201 is rotatably connected to one side of the plurality of hollow columns 202. One end of the rocker 201 passes through the hollow column 202 and is fixedly connected to an active bevel gear 208. A first threaded rod 206 is rotatably connected to the top of the inner side of the hollow column 202. The outer side of the first threaded rod 206 is threadedly connected to a movable column 204. The middle and upper part of the outer wall of the first threaded rod 206 is fixedly connected to a gear from A movable bevel gear 207, a plurality of driven bevel gears 207 are respectively meshed and connected with the corresponding active bevel gears 208, a level ruler 209 is fixedly connected to the front side of the workbench 1, a plurality of liquid level tubes 210 are fixedly connected to the inside of the level ruler 209 at equal intervals, a second slide groove 203 is opened on the left and right sides of the inner walls of the plurality of hollow columns 202, a second slider 205 is fixedly connected to the left and right sides of the outer walls of the plurality of movable columns 204, and the plurality of second sliders 205 are respectively slidably connected to the inside of the corresponding second slide groove 203;

[0035] Specifically, the support mechanism 2 can adjust the height to make the workbench 1 more stable and convenient to use. The horizontal ruler 209 on the front side of the workbench 1 can determine how the support mechanism 2 should be adjusted. The rocker 201 on the outside of the hollow column 202 drives the internal driving gear to rotate, and the meshing driven gear also rotates accordingly, driving the first threaded rod 206 to rotate, and the movable column 204 threadedly connected to the first threaded rod 206 will move, thereby achieving the effect of adjusting the workbench 1 to be stable. The second slide groove 203 and the second slider 205 can effectively move the movable column 204.

[0036] Reference Figure 1 , a storage box 15 is fixedly connected to the left front end of the workbench 1;

[0037] Specifically, the storage box 15 can be used to store tools that workers need to use.

[0038] Reference Figure 4 , an angle ruler 17 is fixedly connected to the middle of the rear side of the workbench 1;

[0039] Specifically, the current tilt angle of the support plate 11 may be observed.

[0040] Reference Figure 1 and Figure 5 A switch 16 is fixedly connected to the front end of the right side of the workbench 1, and the switch 16 is electrically connected to the motor 9. A protective cover 14 is arranged on the outer side of the switch 16, and one side of the protective cover 14 is rotatably connected to the right side of the workbench 1;

[0041] Specifically, the switch 16 can control the running and stopping of the motor 9, and the protective cover 14 has a certain protective effect on the switch 16 to prevent damage and accidental touch during movement and collision.

[0042] Working principle: when using the adjustment pad frame for coal mining, first place the coal mining device on the support plate 11, turn on the switch 16 to let the left and right motors 9 work and drive the second threaded rod 3 to rotate, and at the same time, the first sliders 4 outside the second threaded rods 3 on both sides move outward, so that the first rotating shaft 5 on the top of the two first sliders 4 rotates accordingly, and the second rotating shaft 7 also rotates through the connecting rod 6, so that the connecting rod 6 gradually forms a vertical state to lift the support plate 11 to achieve the effect of adjusting the height. When the angle needs to be adjusted, only one motor 9 can be used according to actual needs to lift one side of the support plate 11 to achieve the effect of adjusting the angle, which not only improves the practicability of the device, but also meets the different needs of users, and when the adjustment pad frame for coal mining is placed in the use position, it can be observed by working The state of the liquid level tube 210 in the horizontal ruler 209 on the front side of the workbench 1, if it is found that the liquid in the liquid level tube 210 is tilted, it means that the adjustment pad frame is in an unstable state. At this time, the four supporting mechanisms 2 under the workbench 1 can be adjusted to make it reach a stable state as needed. When using the supporting mechanism 2, the rocker 201 on the outside of the hollow column 202 drives the active bevel gear 208 inside the hollow column 202 to rotate. Because the driven bevel gear 207 is meshed with the active bevel gear 208, it will also rotate. The first threaded rod 206 fixedly connected to the driven bevel gear 207 will also rotate accordingly, so that the movable column 204 on the outside of the first threaded rod 206 can move up and down. By adjusting the supporting mechanism 2, the workbench 1 can become more stable and convenient for users to use.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
