[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] In this embodiment, refer to Figure 1-Figure 5 , a specific implementation of a vehicle-mounted tool cart that is easy to store includes a frame assembly and a wheel assembly. The wheel assembly includes a wheel body 17 and a hinge structure installed on the upper end of the wheel body 17, the hinge structure includes an upper hinge 1, a lower hinge 2 and a buckle 6, the upper hinge 1 is rotatably installed on one end of the lower hinge 2 through a hinge shaft 3, the upper hinge 1 is fixed on a pressure plate 4, so that the lower hinge 2 can rotate around the hinge shaft 3.

[0022] The wheel body 17 is rotatably mounted on the lower end of the lower hinge 2 , and the buckle 6 is telescopically mounted on the upper end of the upper hinge 1 through the pressing plate 4 .

[0023] The buckle 6 is provided with a fixing groove 18 for accommodating the upper hinge 1 and the lower hinge 2, and the pressure plate 4 is provided with a tension spring 5 for connecting with the buckle 6. Furthermore, a guide portion 16 is provided at one end of the fixing groove 18, so that when the wheel body 17 is opened, the contact surface between the buckle 6 and the hinge structure is provided with the guide portion 16, so that the buckle 6 will move outward under the action of pressure, and the guide portion 16 is designed to be a circular arc surface, or a sloped surface, etc., which will move outward under pressure. When the hinge structure enters the positioning groove, the buckle 6 is reset under the action of the tension spring 5, thereby fixing the hinge structure and making the wheel body 17 stable when in use. When folding the wheel body 17, it is only necessary to pull the buckle 6 outward to release the fixation of the buckle 6 to the hinge structure, so that the wheel body 17 can be folded.

[0024] Furthermore, a handle 13 extending upward is provided at one end of the buckle 6 to facilitate pulling out the buckle 6 .

[0025] Furthermore, a limiting track 19 is provided in the pressing plate 4 , and the buckle 6 can move linearly along the limiting track 19 .

[0026] Furthermore, the frame assembly includes a front frame 9, a rear frame 10 and a frame bottom plate 8, wherein the front frame 9 and the rear frame 10 are connected by a folding structure, wherein the folding structure includes a movable shaft and a movable rod 12, wherein the movable shaft includes a first shaft 14 installed at the upper and lower ends of the front frame 9 and the rear frame 10, and a second shaft 15 for connecting the movable rod 12, and since the movable shaft is fixed, the angle between the movable rods 12 can be changed, so that the front frame 9 and the rear frame 10 can be retracted toward the middle.
