[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please refer to Figures 1-4. In this embodiment of the present invention, a small lifting device that is easy to move includes a base 1, an air pump column 2 for lifting and lowering the hook is installed at the top of the base 1, a traveling wheel 3 for moving the base 1 is installed at the top of the base 1, and a limiting mechanism 4 is provided on the base 1 and the traveling wheel 3 to limit the movement of the traveling wheel 3.

[0031] The limiting mechanism 4 includes a transmission unit and a limiting unit;

[0032] The transmission unit is used to control the movement of the limit unit;

[0033] The limiting unit is used to limit the rotation of the traveling wheel 3;

[0034] =The limiting unit includes a limiting block 401 and a gear 402;

[0035] The limiting block 401 is vertically slidably installed on the outer wall of the traveling wheel 3. The limiting block 401 is used to limit the rotation of the gear 402.

[0036] Gear 402 is fixed to the outer wall of the wheel shaft of the traveling wheel 3. Gear 402 is used to synchronously drive the wheel of the traveling wheel 3 to rotate.

[0037] The transmission unit includes a guide rod 403, a movable rod 404, a pressing ring 405, a spring 406, and a connecting rod 407;

[0038] The guide rod 403 is vertically slidably installed inside the base 1, and the guide rod 403 is used to synchronously drive the pressing ring 405 to move;

[0039] The movable rod 404 is axially slidably connected to the inner wall of the guide rod 403 and extends to the outside of the base 1. The movable rod 404 is used to limit the vertical movement of the guide rod 403.

[0040] The pressing ring 405 is fixed to the bottom end of the guide rod 403. The pressing ring 405 is used to apply downward pressing force to the limiting block 401.

[0041] The two ends of the spring 406 are respectively engaged inside the base 1 and the top of the guide rod 403. The spring 406 is used to give the guide rod 403 a downward compressive force.

[0042] The connecting rod 407 is fixed to the outer wall of the pressing ring 405. The connecting rod 407 is used to synchronously drive the two pressing rings 405 to move synchronously.

[0043] In this embodiment: When using this device, by moving the base 1 to the desired position, and by applying a pushing force to one side to the movable rod 404 using the foot, the movable rod 404 moves axially along the "L"-shaped sliding groove on the outer wall of the base 1, causing the movable rod 404 to contact the "L"-shaped sliding vertical groove. At this time, the movable rod 404 will drive the guide rod 403 to move downward synchronously under the elastic force of the spring 406. The downward-moving guide rod 403 will also drive the pressing ring 405 to move synchronously. The pressing ring 405, which surrounds the outer wall of the traveling wheel 3, will move downward along the outer wall of the traveling wheel 3. The pressure ring 405 contacts the top of the limiting block 401, giving the limiting block 401 a downward pushing force. The limiting block 401 gives the elastic block a squeezing force, and the bottom end of the limiting block 401 will also be engaged in the tooth groove of the gear 402, limiting the rotation of the gear 402, thereby limiting the rotation of the traveling wheel 3. The downward movement of the pressure ring 405 will also drive another pressure ring 405 to move downward through the connecting rod 407, thereby giving another limiting block 401 a downward squeezing force. This achieves the purpose of simultaneously limiting the rotation of multiple traveling wheels 3, further improving work efficiency.

[0044] Please refer to Figures 1-4. The guide rod 403 has an "L"-shaped sliding groove inside for one end of the movable rod 404 to move axially. The outer wall of the base 1 has a movable groove for the movable rod 404 to move in an "L" shape. The outer wall of the guide rod 403 is in an "L" shape. The bottom end of the "L" shape of the guide rod 403 is fixedly connected to the top end of the pressing ring 405. The pressing ring 405 is in a hollow ring structure. The pressing ring 405 surrounds the outer wall of the traveling wheel 3. The inner wall of the traveling wheel 3 has a groove for the vertical movement of the limiting block 401. An elastic block that provides an upward elastic thrust to the limiting block 401 is installed in the groove.

[0045] In this embodiment: when the base 1 needs to be moved, the movable rod 404 can be pushed upward by this structure, so that the movable rod 404 moves along the "L"-shaped movable groove of the base 1. When the movable rod 404 moves to the corner of the movable groove, the movable rod 404 is pushed axially, so that the movable rod 404 abuts in the transverse sliding groove of the "L"-shaped movable groove, thereby limiting the vertical movement of the guide rod 403.
