[0021] Depend on Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the utility model includes a connecting plate 10, a first support plate 11 and a second support plate 12 detachably connected to the connecting plate 10, a support plate 13 hingedly connected between the first support plate 11 and the second support plate 12, and a baffle 14 vertically arranged on one side of the support plate 13, and the other side of the support plate 13 is provided with a partition 15 screwed to the second support plate 12. The first support plate 11, the second support plate 12, the support plate 13, the baffle 14 and the partition 15 together form a box structure that can carry objects; a limit assembly is provided on the first support plate 11, the support plate 13 is fixedly connected to one end of the hose 2, and the other end of the hose 2 is provided with a wrench assembly for installing and removing tire bolts; a roller 16 is provided on the support plate 13.

[0022] Specifically, the first support plate 11 and the second support plate 12 are both screwed to the connecting plate 10 , and a cover plate 17 is screwed between the first support plate 11 and the second support plate 12 .

[0023] The limiting assembly includes a connecting rod 20 hingedly arranged on the outer side wall of the first support plate 11, a positioning groove 111 is provided on the first support plate 11 at a position corresponding to the connecting rod 20, and a limiting groove 202 is provided on the connecting rod 20 at a position corresponding to the positioning groove 111. A limiting pin 201 is passed through the non-hinge end of the connecting rod 20, and an insertion hole is provided on the first support plate 11 at a position corresponding to the limiting pin 201. The protruding end of the limiting pin 201 extends into the insertion hole, so that the connecting rod 20 is fixedly connected to the first support plate 11, and the positioning groove 111 and the limiting groove 202 together form a hole-shaped structure.

[0024] The wrench assembly includes a sleeve 21 connected to one end of the hose 2, a bearing is embedded in the sleeve 21, a support rod 22 is passed through the center hole of the bearing, a handle 23 is provided at one end of the support rod 22, and a connecting shaft 24 for sleeve-connecting the sleeve head is provided at the other end.

[0025] Four rollers 16 are provided at the lower end of the support plate 13 , and upwardly convex grooves are provided at positions corresponding to the rollers 16 on the support plate 13 . A support rod 25 is passed through each roller 16 , and its two ends are respectively connected to the groove walls on both sides of the corresponding groove.

[0026] The baffle 14 is provided with a clearance groove 141 for the support rod 22 to move; the second support plate 12 is provided with a storage groove 121.

[0027] The operating principle of this utility model is as follows:

[0028] like Figures 1 to 4As shown, before changing the tire, the first support plate 11 and the second support plate 12 are flipped to a vertical position and screwed to the connecting plate 10 respectively, and the vertically placed partition 15 is screwed to the second support plate 12. In this way, the first support plate 11, the second support plate 12, the support plate 13, the baffle 14 and the partition 15 together form a box structure that can carry objects, and the jack (not marked), the hose 2 and the sleeve 21 connected to it and the support rod 22 are all placed in the box structure, and then the cover plate 17 is screwed to the upper end surfaces of the first support plate 11 and the second support plate 12. In this way, a tool box that can prevent falling is formed; at this time, the protruding end of the limit pin 201 extends into the insertion hole to fix the connecting rod 20 on the first support plate 11.

[0029] When the tire needs to be changed, unscrew and remove the cover plate 17, take out the jack, and then remove the partition 15. Finally, remove the first support plate 11 and the second support plate 12 from the connecting plate 10, flip the two support plates, and make the upper end surfaces of the two support plates flush with the upper end surface of the support plate 13, and place the support plate 13 on the ground.

[0030] Next, use a jack to lift the vehicle frame and lift the damaged tire off the ground. Then, remove the limit pin 201, flip the connecting rod 20 horizontally outward to expose the notch of the positioning groove 111, move the positioning groove 111 to the outer wall position of the jack, move the connecting rod 20 back, and insert the limit pin 201 into the socket. In this way, the positioning groove 111 and the limit groove 202 together form a hole-like structure that is sleeved on the outside of the jack, and the support plate 13 can only move in a horizontal circular direction with the jack position as the center; therefore, before placing the jack, it is necessary to determine the placement position of the support plate 13 to avoid misalignment between the tire and the support plate 13.

[0031] Subsequently, the support plate 13 is pushed under the tire to be replaced, and the height of the frame is lowered by the jack, that is, the lower end wheel surface of the tire is lowered to a position where it is in contact with the upper end surface of the support plate 13. At this time, not only the height difference of the tire falling is reduced, but the baffle 14 can also prevent the tire from tipping over after it becomes loose. At the same time, the convex groove corresponding to the position of the roller 16 also limits the rotation of the tire in the front and rear directions. In addition, the socket connection between the roller 16 and the jack ensures the stability of removing the tire and putting in the new tire.

[0032] Finally, insert the sleeve head on the connecting shaft 24, align the sleeve head with the wheel hub bolts, and pull the handle 23 to remove the wheel hub bolts and remove the tire in turn. During use, in order to prevent interference in use, a clearance groove 141 is provided on the baffle 14 to prevent interference in use of the support rod 22, so as to facilitate the movement of the sleeve head in a certain range of upper and lower positions, so as to quickly tighten the bolts; since the clearance groove 141 is only provided on one side of the baffle 14, before removing the last wheel hub bolt, it is necessary to adjust the jack to lift the frame, rotate the wheel, and move the unremoved bolts to the position of the clearance groove 141, then lower the frame, and remove the wheel hub bolts according to the above-mentioned relevant content; similarly, place the new tire on the support plate 13, adjust the alignment height with the screw hole by the jack, and tighten the wheel hub bolts in turn.

[0033] After changing the tire, push out the support plate 13, remove the limit pin 201, move the first support plate 11 from the outside of the jack, screw the first support plate 11 and the second support plate 12 to the connecting plate 10, screw the partition 15, put the jack, hose 2 and its connected sleeve 21 and support rod 22 into the enclosed box structure, and screw the box cover 17.

[0034] It should be pointed out that, for special off-road vehicle styles, the utility model can be placed in the trunk, that is, a box structure formed by an internal enclosure; and for large vehicles, the connecting plate 10 can also be connected to the vacant and exposed position of the frame of the large vehicle, so as to screw and disassemble the first support plate 11 and the second support plate 12, that is, a box structure formed by an external enclosure, which is flexible to use and has a wide range of applications.

[0035] In order to facilitate the placement of bolts and other tools and materials, a storage groove 121 is provided on the second support plate 12 .

[0036] In order to reduce weight and facilitate manual movement, the first support plate 11, the second support plate 12, the supporting plate 13, the baffle 14, the partition plate 15 and the cover plate 17 are all made of nylon 66 material, which is light and has high strength.
