When there is a higher shelf on one side and no shelf on the other side in the service position, the support frame 2 on one side is put on the shelf, and if the ground is slippery, the support frame 2 may slide from the shelf to a lower position. To solve this problem, in this embodiment, specifically, the universal wheel 3 includes a steering shaft 3-1 and a wheel body 3-2, the wheel body 3-2 is rotatably connected to one end of the steering shaft 3-1, the rotation axis of the wheel body 3-2 is perpendicular to the steering shaft 3-1, the rotation axis of the wheel body 3-2 is located at the side of the steering shaft 3-1, the center of gravity of the universal wheel 3 is located at one side of the rotation axis of the wheel outside the central axis of the steering shaft 3-1, and the wheel body 3-2 is rotatably connected to the end of the support frame 2 through the steering shaft 3-1.
The rotating shaft of the wheel body 3-2 is positioned at the side part of the steering shaft 3-1, and the gravity center of the universal wheel 3 is positioned at one side of the rotating shaft of the wheel outside the central axis of the steering shaft 3-1, so that the wheel body 3-2 always enables the rotating shaft to downwards under the action of gravity, and the wheel body 3-2 can be used as a limiting mechanism to limit the rotating shaft to downwards slide.
Further, the gesture control mechanism comprises a remote controller 6, a controller 5, a first rotating shaft 1-1, a second rotating shaft 2-1 and an electric telescopic rod 4-6; the first rotating shaft 1-1 is fixedly connected to the main frame body 1, and the first rotating shaft 1-1 is parallel to the connecting rotating shaft 1-2; the second rotating shaft 2-1 is rotatably connected to the supporting frame 2, and the supporting frame 2 is parallel to the connecting rotating shaft 1-2; the electric telescopic rod 4-6 is respectively connected with the first rotating shaft 1-1 and the second rotating shaft 2-1 in a rotating mode, the electric telescopic rod 4-6 is electrically connected with the controller 5, and the controller 5 is electrically connected with the remote controller 6.

When the electric telescopic rod is unfolded, the closer the included angle between the support frame 2 and the main frame body 1 is to 180 degrees, the smaller the included angle between the electric telescopic rod 4-6 and the support frame 2 is, so that the smaller the moment for the electric telescopic rod 4-6 to rotate the support frame 2 is, and when the space of a position to be overhauled is very narrow, the device can possibly be lifted and cannot be overhauled;
After folding, when the included angle between the support frame 2 and the main frame body 1 is closer to 0 degree, the angle between the electric telescopic rod 4-6 and the support frame 2 is closer to 180 degrees, so that the moment for rotating the support frame 2 by the electric telescopic rod 4-6 is smaller, and the support frame 2 is difficult to unfold or the second rotating shaft 2-1 is easy to crush when being unfolded again.
In order to solve this problem, in this embodiment, further, the second rotating shaft 2-1 includes a main shaft 2-1-1 and a secondary shaft 2-1-2, the main shaft 2-1 includes two main shafts 2-1-1 respectively fixedly connected to two ends of the secondary shaft 2-1-2; the main shaft 2-1-1 is rotationally connected to the support frame 2 through an angle limiter 2-2, the angle limiting range of the angle limiter 2-2 is-90 degrees to 90 degrees, the angle limiter 2-2 limits the secondary shaft 2-1-2 to the side, far away from the electric telescopic rod 4-6, of the support frame 2, and the plane where the secondary shaft 2-1-2 and the main shaft 2-1-1 are located is perpendicular to the support frame 2; the angle limiter 2-2 limits the secondary shaft 2-1-2 to be positioned on one side of the support frame 2 close to the electric telescopic rod 4-6 when the angle is 90 DEG, and the plane of the secondary shaft 2-1-2 and the main shaft 2-1-1 is vertical to the support frame 2; the secondary shaft 2-1-2 is parallel to but not coincident with the primary shaft 2-1-1, and the second rotating shaft 2-1 is rotatably connected with the electric telescopic rod 4-6 through the secondary shaft 2-1-2.
When the included angle between the support frame 2 and the main frame body 1 is more approximate to 180 degrees, the electric telescopic rod 4-6 contracts and pulls the secondary shaft 2-1-2 of the second rotating shaft 2-1 to rotate around the main shaft 2-1-1, and the plane where the secondary shaft 2-1-2 and the main shaft 2-1-1 are located is perpendicular to the support frame 2 under the limitation of the angle limiter 2-2. Therefore, the included angle between the electric telescopic rod 4-6 and the supporting frame 2 is more close to 90 degrees, and the same pulling force can provide larger moment, so that the lifting capacity of the device is improved.
Although the moment of rotating the support frame 2 is still small after the electric telescopic rod 4-6 is folded, the electric telescopic rod 4-6 stretches in the unfolding process to push the secondary shaft 2-1-2 to rotate around the main shaft 2-1-1 until the included angle between the electric telescopic rod 4-6 and the support frame 2 approaches to the position of-90 degrees, at this time, the included angle between the electric telescopic rod 4-6 and the support frame 2 is closed to 90 degrees, so that the moment of rotating the support frame 2 by the electric telescopic rod 4-6 is increased, the support frame 2 and the main frame body 1 are easier to unfold, and the possibility of damage to the second rotating shaft 2-1 is reduced.
In order to solve this problem, in this embodiment, further, the first rotating shaft 1-1 is adjustably connected to the main frame 1 along the length direction of the main frame 1 through a position adjusting mechanism, because the stroke of the electric telescopic rod 4-6 is limited, so that the change of the included angle between the supporting frame 2 and the main frame 1 is limited.
