A leveling mechanism 2 is installed around the bottom end of the base 3, pillars 9 are installed on both sides of the upper end of the base 3, an adjusting rod 10 is installed on the inner side of the pillar 9, a sliding sleeve 5 is installed on one side of the bottom end of the adjusting rod 10, the sliding sleeve 5 is slidably installed on the upper side of the pillar 9, a first fixing bolt 6 is installed on the outer side of the sliding sleeve 5, the bottom end of the adjusting rod 10 is installed on the upper side of the adjusting mechanism 8, the bottom end of the adjusting mechanism 8 is installed on the upper end of the base 3, a battery 13 is installed inside the base 3, the bottom end of the buffer mechanism 12 is installed on the upper end of the adjusting rod 10, and the bottom end of the top plate 11 is installed on the upper side of the buffer mechanism 12.

[0032] The application of one aspect of this embodiment is: when in use, the supporting device 1 is placed at a specified position through the base 3, and the base 3 is leveled by the leveling mechanism 2. When support is needed, the adjusting mechanism 8 drives the adjusting rod 10 to move upward, and the adjusting rod 10 drives the top plate 11 to move. After the adjusting rod 10 is moved, the sliding sleeve 5 pillar 9 is fixed by the first fixing bolt 6, so that the adjusting rod 10 and the pillar 9 can be fixed. In this utility model, the adjusting mechanism 8 drives the adjusting rod 10 to move upward, and the height of the supporting device 1 is adjusted by the adjusting rod 10, so as to facilitate the support of lanes at different heights, and the lanes are temporarily supported by the top plate 11. During support, the support of the lanes is buffered by the buffer mechanism 12.

[0033] In this embodiment, the leveling mechanism 2 is composed of a threaded rod 24 and a threaded barrel 23. The threaded barrel 23 is installed around the bottom end of the base 3, and the threaded rod 24 is rotatably installed inside the threaded barrel 23. When the leveling mechanism 2 is in use, the threaded rod 24 is rotated. When in use, the threaded rod 24 is moved up and down by the action of the threaded barrel 23, so that the base 3 can be leveled, which facilitates the stable placement of the base 3.

[0034] In this embodiment, a handle 21 is installed at the upper end of the threaded rod 24, and a base plate 25 is rotatably installed at the lower end of the threaded rod 24. A friction pad 20 is attached to the lower end of the base plate 25 by adhesive. The handle 21 is provided for the convenience of the staff to hold it, thereby facilitating the rotation of the threaded rod 24. The base plate 25 is provided for increasing the contact area between the bottom end of the base plate 25 and the ground, and the friction pad 20 is provided for increasing the friction between the bottom end of the base plate 25 and the ground to avoid the base plate 25 sliding during use.

[0035] In this embodiment, a second fixing bolt 22 is provided on the outside of the threaded barrel 23. The second fixing bolt 22 is rotatably installed on the outside of the threaded barrel 23. When in use, the second fixing bolt 22 can increase the friction between the threaded rod 24 and the threaded barrel 23, thereby avoiding the phenomenon of thread slippage between the threaded barrel 23 and the threaded rod 24 during use.

[0036] In this embodiment, the buffer mechanism 12 is composed of an insertion rod 17 and a mounting tube 16. The mounting tube 16 is installed at the upper end of the pillar 9, and the insertion rod 17 is installed at the lower end of the top plate 11. The lower end of the insertion rod 17 is inserted into the mounting tube 16. A spring 19 is installed inside the mounting tube 16 at the lower end of the insertion rod 17. When the buffer mechanism 12 is in use, when the top plate 11 contacts the tunnel, the insertion rod 17 will shrink due to the action of the spring 19. During the support process, the buffer mechanism 12 buffers the top plate 11 to avoid high instantaneous pressure, and buffers the pressure on the pillar 9 and the adjusting rod 10 to avoid bending of the pillar 9 and the adjusting rod 10 during use.

[0037] In this embodiment, a limiting column 15 is installed at the bottom end of the mounting tube 16, and a damping sleeve 18 is installed at the upper end of the mounting tube 16, which is located outside the insertion rod 17. The limiting column 15 is provided to limit the contraction range of the spring 19 to avoid that the insertion rod 17 exerts a large pressure on the spring 19 during use, causing the spring 19 to lose its elasticity. The damping sleeve 18 is provided to increase the resistance between the insertion rod 17 and the mounting tube 16 to avoid the insertion rod 17 from shaking during use.

[0038] In this embodiment, the adjusting mechanism 8 is composed of a screw rod 7, a screw rod nut 4 and a motor 14. The screw rod nut 4 is installed between the bottom ends of the adjusting rod 10, the screw rod nut 4 is rotatably installed at the outer side of the screw rod 7, the bottom end of the screw rod 7 is rotatably installed at the upper end of the base 3, the bottom end of the screw rod 7 passes through the base 3 and is installed on the upper side of the motor 14, and the motor 14 is installed inside the base 3. When the adjusting mechanism 8 is in use, the motor 14 is turned on by a switch, and the motor 14 will drive the screw rod 7 to rotate. During the rotation process, the screw rod 7 will drive the adjusting rod 10 to move upward through the screw rod nut 4 and be supported by the adjusting rod 10.
