The inner wall of the receiving cavity 303 is provided with a guide groove 304 and a limiting groove 305. The outer side of the first extending panel 301 is provided with a guide rod 306 and a stop block 307.

[0028] The side panels 3 can be extended or retracted to both sides by the first extension panel 301 and the second extension panel 302;

[0029] The retraction mechanism 6 is specifically composed of a storage tube 601, a retraction rod 602 and a limiting plate 603. The retraction rod 602 is provided in the storage tube 601, and a limiting plate 603 is provided at one end of the retraction rod 602.

[0030] The limiting plate 603 can prevent the retractable rod 602 from being separated from the storage tube 601 .

[0031] In this embodiment, the limiting plate 603 is fixedly mounted on one end of the retractable rod 602, and one end of the retractable rod 602 extends into the storage tube 601. The retracting mechanism 6 has several groups. The end of the storage tube 601 is adapted to the retractable rod 602, and the limiting plate 603 is adapted to the internal space of the storage tube 601. The outer sides of the limiting plate 603 and the retractable rod 602 are coated with silicone and fit closely to the storage tube 601.

[0032] Specifically, the storage tube 601 can provide the retractable rod 602 with sufficient retracting space, and the silicone setting ensures the friction between the retractable rod 602, the limiting plate 603 and the storage tube 601 to prevent the vehicle body from shaking due to overly sensitive retraction.

[0033] In this embodiment, a plurality of groups of retracting mechanisms 6 are fixedly connected end to end to form side bars 5. There are four groups of side bars 5 and they form a square structure. The cross bars 7 are fixedly installed in the square structure formed by the side bars 5. The cross bars 7 have the same structure as the side bars 5.

[0034] Specifically, the cross bars 7 can support the square structure formed by the side bars 5 .

[0035] In this embodiment, the connecting net 8 is fixedly installed between the cross bars 7 and between the cross bars 7 and the side bars 5, and the moving wheels 2 are fixedly installed at the bottom of the base frame 1 and at the four corners;

[0036] Specifically, the movable wheels 2 can ensure the flexible movement of the entire tool cart.

The first extending plate 301 is installed in the receiving cavity 303, and the guide rod 306 corresponds to the guide groove 304, and the limit block 307 corresponds to the limiting groove 305.

[0038] Specifically, the guide rod 306 and the guide groove 304 can make the first extension plate 301 and the second extension plate 302 more stable when extending and retracting to avoid tilting. The limiting groove 305 and the limit block 307 can limit the extension length of the first extension plate 301 and the second extension plate 302.

[0039] In this embodiment, the outer side of the second extension plate 302 is provided with a correspondingly sized stopper 307 and a guide rod 306. The first extension plate 301 is provided with a receiving cavity 303, a guide groove 304, and a limiting groove 305 adapted for the second extension plate 302. The mounting structure of the second extension plate 302 is the same as that of the first extension plate 301. The outer sides of the first and second extension plates 301, 302 are both coated with silicone.

[0040] Specifically, the silicone covering the outer sides of the first extension plate 301 and the second extension plate 302 can ensure the friction between the first extension plate 301, the second extension plate 302 and the corresponding storage cavity 303 to prevent the vehicle body from shaking due to excessive contraction.

[0041] In this embodiment, there are four groups of side panels 3 with the same structure. The connecting rods 4 are fixedly installed at the four corners of the top of the base frame 1. The second extension panels 302 of two adjacent groups of side panels 3 are fixedly connected to the connecting rods 4. The bottom of the side panels 3 except the first extension panels 301 and the second extension panels 302 are fixedly connected to the side rods 5.

[0042] Specifically, the side bars 5 can form an overall frame of the base frame 1 .

[0043] When the tool trolley is in a state of being moved, the lifting device 21 can be used to lift the tool trolley and adjust the size of the tool trolley so that the lifting device 21 is in a state of being moved.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
