[0025] For details, see Figure 1 The support base 1 is provided with supporting feet 14 , which are distributed on the support base 1 in a triangular shape. The support base 1 is provided with rollers 15 , and the bottom ends of the rollers 15 are higher than the bottom ends of the supporting feet 14 .

[0026] Preferably, the support base 1 is a triangular plate-shaped structure, and support plates 16 are symmetrically provided on the side walls of the support base 1 . A rotating shaft 17 is provided on the support plate 16 , and the roller 15 is installed on the rotating shaft 17 .

[0027] Preferably, the legs 14 are welded at three corners of the support base 1 .

[0028] In the above setting, the support foot 14 contacts the ground to provide support for the support base 1, so that the entire bracket is stably placed on the ground, providing stable support for the entire bracket. The setting of the roller 15 allows the bracket to be tilted so that the roller 15 contacts the ground when moving the entire bracket, and the support foot 14 is off the ground, making it easier to move the entire bracket.

[0029] For further information, see Figure 2 A sliding cavity 18 is provided inside the supporting sleeve 2, the inner diameter of the sliding cavity 18 is larger than the outer diameter of the moving sleeve 3, and the moving sleeve 3 is slidably installed in the sliding cavity 18; the limiting member 7 includes a vertical groove 701 arranged on the inner wall of the sliding cavity 18 and a slider 702 arranged on the outer wall of the moving sleeve 3, and the slider 702 is slidably connected to the vertical groove 701.

[0030] Preferably, the support sleeve 2 is a hollow cylinder, and a sliding cavity 18 is formed in the hollow interior of the support sleeve 2 .

[0031] Preferably, the vertical groove 701 runs through the entire sliding cavity 18 , and the sliding block 702 is arranged at the bottom end of the movable sleeve 3 adjacent to the supporting base 1 .

[0032] In the above arrangement, the slider 702 is slidably connected to the vertical groove 701 to limit the freedom of the movable sleeve 3 so that the movable sleeve 3 can only move up or down along the supporting sleeve 2, thereby preventing the movable sleeve 3 from rotating when the adjusting sleeve 8 and the movable sleeve 3 are threaded.

[0033] For further information, see Figure 3 A first meshing tooth 19 is provided on the outer wall of the adjusting sleeve 8, and an internal thread is provided on the inner wall of the adjusting sleeve 8; a second meshing tooth 20 is provided on the outer wall of the adjusting rod 9, and the axis of the adjusting rod 9 is skewed and perpendicular to the axis of the adjusting sleeve 8, and the first meshing tooth 19 meshes with the second meshing tooth 20.

[0034] Preferably, the adjusting sleeve 8 is a turbine and the adjusting rod 9 is a worm.

[0035] Preferably, an external thread is provided on the outer wall of the movable sleeve 3 .

[0036] In the above arrangement, by rotating the adjusting rod 9, the first meshing teeth 19 and the second meshing teeth 20 are meshed, driving the adjusting sleeve 8 to rotate, and under the action of the thread, the movable sleeve 3 moves up or down in the sliding cavity 18.

[0037] For further information, see Figure 1 , 3 A mounting shell 21 is provided on the end of the movable sleeve 3 away from the supporting base 1 , and a mounting cavity 22 is provided in the mounting shell 21 . The adjusting rod 9 and the adjusting sleeve 8 are both rotatably arranged in the mounting cavity 22 .

[0038] Preferably, the mounting shell 21 is a hollow cylinder with openings at both ends, the hollow interior of the mounting shell 21 is connected to the sliding cavity 18, the mounting cavity 22 is a circular cavity arranged on the inner wall of the hollow interior of the mounting shell 21, and the mounting cavity 22 is parallel to the horizontal plane.

[0039] Preferably, a first through hole 23 and a second through hole 24 are coaxially disposed on the inner wall of the installation cavity 22 , and one end of the adjustment rod 9 passes through the first through hole 23 and is rotatably connected to the second through hole 24 .

[0040] Preferably, a handle 25 is provided on one end of the adjusting rod 9 located outside the first through hole 23 .

[0041] In the above arrangement, the adjusting sleeve 8 is installed in the installation cavity 22 to limit the position of the adjusting sleeve 8. The adjusting rod 9 is driven to rotate by rotating the rotating handle 25, thereby driving the adjusting sleeve 8 to rotate.

[0042] For further information, see Figure 4 The moving rod 10 is provided with a limit rod 26 located in the observation window 5; the distance from the top of the identification ring 13 to the bottom of the tray 11 is equal to the distance from the top of the reference line 6 to the top of the moving sleeve 3.

[0043] Preferably, the identification ring 13 and the identification line are both formed by spraying yellow paint.

[0044] Preferably, the resilient member 12 is a spring.

[0045] In the above arrangement, the setting of the limit rod 26 prevents the bearing tray 11 from separating from the movable sleeve 3; when the bearing tray 11 moves up with the movable sleeve 3 and abuts against the automobile chassis, the spring is compressed, and the movable rod 10 moves toward the bottom of the sliding cavity 4. When the identification ring 13 is aligned with the identification line, the bottom of the bearing tray 11 is in contact with the top of the movable sleeve 3, so that the bearing tray 11 abuts against the automobile chassis to provide stable support for the automobile chassis.

[0046] In this embodiment, the support base 1 provides stable support for the entire bracket, and the adjusting rod 9 is driven to rotate by rotating the handle 25, and the adjusting sleeve 8 is driven to rotate under the meshing of the first meshing tooth 19 and the second meshing tooth 20, and the movable sleeve 3 is moved upward under the action of the thread, thereby driving the bearing tray 11 to move up and abut against the automobile chassis. After the bearing tray 11 is subjected to force, the movable rod 10 compresses the spring. As the movable sleeve 3 moves upward, the observation window 5 moves upward accordingly, so that the identification ring 13 is aligned with the reference line 6, so that the bearing tray 11 abuts against the top of the movable sleeve 3, providing stable support for the automobile chassis; the adjusting rod 9 and the adjusting sleeve 8 respectively adopt a worm gear and a turbine. Through the self-locking of the turbine, the movable sleeve 3 cannot drive the adjusting sleeve 8 to rotate, so that the entire bracket is more stable when supporting the automobile chassis.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
