[0024] Furthermore, the reinforcement assembly includes a threaded rod 12, an internal threaded sleeve 13, a hinged rod 14, a through hole 15, a reinforcement rod 16, a bevel gear A17, a rotating rod 18 and a bevel gear B19. The bottom of the adjusting plate 3 is sleeved with a threaded rod 12, and the top of the threaded rod 12 is provided with a bevel gear B19. The top of one end of the adjusting plate 3 is sleeved with a rotating rod 18, and one end of the rotating rod 18 extends to the outside of the adjusting plate 3 and is provided with a rotating wheel. The operator can rotate the rotating rod A18 through the rotating wheel. A bevel gear A17 meshing with a bevel gear B19 is provided at one end of 18, three groups of through holes 15 are respectively provided at the bottom of both sides of the adjustment plate 3, and reinforcing rods 16 are sleeved on the inner sides of the six groups of through holes 15, and three groups of internal threaded sleeves 13 are threadedly connected to the outer sides of the threaded rod 12, and hinged rods 14 are hinged on both sides of the three groups of internal threaded sleeves 13, and multiple groups of hinged rods 14 are hinged to the six groups of reinforcement rods 16 on one side away from the threaded rod 12, which can improve the fixing stability of the support leg 2 inserted into the ground.

[0025] Furthermore, the anti-skid ball 4 is made of rubber material, so that the anti-skid ball 4 has a higher friction force, which can improve the anti-skid performance of the device.

[0026] Furthermore, a limit block is provided at the bottom of the outer side of the insertion rod 9, the bottom of the spring 11 is connected to the limit block, and a shift block is provided at the top of the insertion rod 9, which can facilitate pulling the insertion rod 9, and the range of motion of the insertion rod 9 can be limited by the limit block.

[0027] Furthermore, a limiting plate is provided on the top of one side of the inner part of the adjustment plate 3, and the threaded rod 12 is rotationally connected with the limiting plate to cooperate with each other, so as to limit the threaded rod 12 and improve its fixing stability.

[0028] Working principle: When the device is placed in a soft soil area, the three groups of legs 2 can be spread out and inserted into the ground through the plug block 6. Then the operator can rotate the rotating rod 18 through the rotating wheel, and then drive the bevel gear A17 through the rotating rod 18, so that the bevel gear A17 can drive the threaded rod 12 to rotate through the engagement with the bevel gear B19. When the threaded rod 12 rotates, it can drive the internal thread sleeve 13 to move downward, and then the internal thread sleeve 13 can push the multiple groups of reinforcement rods 16 to extend out of the through hole 15 and insert into the ground to form barbs under the connection of the hinged rod 14, so that the three groups of legs 2 are stably fixed to prevent the legs 2 from sliding;

[0029] When the device is used on a hard ground, the plug rod 9 can be pulled out of the socket 7 by pulling the pull block to overcome the elastic force of the spring 11. At this time, the fixation of the adjustment plate 3 can be released, and then the adjustment plate 3 is flipped 180 degrees to exchange the positions of the anti-slip balls 4 and the plug block 6. The elastic force of the spring 11 is used to push the plug rod 9 into another set of sockets 7. The device can be placed on the ground through the anti-slip balls 4, which greatly improves the friction at the bottom of the device and prevents the device from sliding on the hard ground.
