Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be known that the present utility model provides a technical solution: a tool cart with an extendable tabletop, including a tool cart body 1, universal wheels 2 and a handle 3;

[0023] The bottom end of the tool cart body 1 is provided with universal wheels 2. One side of the tool cart body 1 is welded with a handle 3. The top end of the tool cart body 1 is provided with an extension mechanism 4 extending to the outside. The extension mechanism 4 includes a threaded rod 401, a rotating wheel 402, an extension plate 403, a support arm 404, an empty slot 405, a locking rod 406, a pull ring 407, a spring 408, a locking slot 409 and a bolt 410. The top end inside the tool cart body 1 is provided with a threaded rod 401 connected by a bearing. One side of the threaded rod 401 is welded with a rotating wheel 402 extending to the outside of the tool cart body 1. The surface of the threaded rod 401 is threadedly connected with an extension plate 403. One side of the tool cart body 1 away from the handle 3 is rotatably connected with a support arm 404 connected to the extension plate 403 through a hinge seat. An empty slot 405 is opened inside the top end of the support arm 404. Symmetrically distributed locking rods 406 are arranged inside the empty slot 405. One end of the locking rod 406 is welded with a pull ring 407 extending to the outside of the support arm 404. A spring 408 is welded between the locking rod 406 and the empty slot 405. One end of the extension plate 403 close to the locking rod 406 is provided with a locking slot 409. A bolt 410 is arranged on the surface of the support arm 404. One end of the locking rod 406 is welded with a T-shaped slider 5. A T-shaped sliding groove 6 is opened at one end of the empty slot 405 close to the T-shaped slider 5. The locking rod 406 and the empty slot 405 form a sliding structure through the T-shaped slider 5 and the T-shaped sliding groove 6.

[0024] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 it can be known that by rotating the rotating wheel 402 to drive the extension plate 403 to move, and rotating the support arm 404 to support the extension plate 403. By pinching the pull ring 407, the locking rod 406 is placed inside the extension plate 403. Through the reset effect of the spring 408, the locking rod 406 can be locked with the locking slot 409, so that the support arm 404 can be fixed at the bottom end of the extension plate 403, making the extension plate 403 more stable during use.

[0025] Referring to Figure 1 , Figure 2 and Figure 5 it can be known that a stable placement mechanism 7 is arranged at the bottom end of the tool cart body 1. The stable placement mechanism 7 includes a fixed seat 701, a gear 702, a motor 703, a rack 704 and a stable seat 705. The bottom end of the tool cart body 1 is provided with a fixed seat 701. Symmetrically distributed gears 702 are connected inside the fixed seat 701 through a support shaft. A motor 703 connected by a coupling is installed outside the fixed seat 701. One side of the gear 702 is meshed with a rack 704 extending to the outside of the fixed seat 701. The bottom end of the rack 704 is welded with a stable seat 705.

[0026] Referring to Figure 1 ,Figure 2 and Figure 5 It can be seen that by starting the motor 703 to drive the rack 704 and the stable seat 705 to move, the stable seat 705 can be in contact with the ground when moving to support the tool vehicle body 1, so that the tool vehicle body 1 can be more stable when placed and used.

[0027] In summary, the tool vehicle is a common tool, which is usually used in locomotive assembly. When the tool vehicle body 1 is in use and the tabletop of the tool vehicle body 1 is not enough, in this process, by rotating the runner 402 to drive the threaded rod 401 to rotate, at the same time the threaded rod 401 drives the extension plate 403 to move, and the rotating support arm 404 can support the extension plate 403. By pinching the pull ring 407, the locking rod 406 can squeeze the spring 408, so that the locking rod 406 is placed inside the extension plate 403. Through the reset effect of the spring 408, the locking rod 406 can be locked with the locking groove 409, so that the support arm 404 can be fixed at the bottom end of the extension plate 403, making the extension plate 403 more stable when in use, and thus making it more convenient for the tool vehicle body 1 to extend the tabletop. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
