[0025] When using the tire frame, the two bases 1 are placed horizontally on the ground at a certain distance, and then the bottom ends of the two connecting rods 23 are respectively snapped into the mounting holes 22. At this time, the guide rod 24 is extended and retracted according to the distance between the two bases 1, so that a certain limit can be set between the two bases 1, which is convenient for subsequent use.

[0026] The vertical pole 2 is provided with a first adjustment component 4 for adjusting the height of the L-shaped support frame 3, the first adjustment component 4 includes a T-shaped slot 7 evenly provided on the vertical pole 2, a T-shaped block 8 is fixedly provided on one side of the L-shaped support frame 3, the T-shaped block 8 cooperates with the T-shaped slot 7, a card slot 9 is provided above the T-shaped slot 7 on one side of the vertical pole 2, a hydraulic telescopic rod 10 is fixedly provided on one side of the L-shaped support frame 3, and the other end of the hydraulic telescopic rod 10 cooperates with the card slot 9;

[0027] The base 1 is provided with a second adjustment component 5 for adjusting the vertical pole 2, the second adjustment component 5 includes a bidirectional screw 11 rotatably arranged in the base 1, a symmetrical screw block 12 is slidably arranged in the base 1, the screw block 12 is threadedly connected to both ends of the bidirectional screw 11, and two screw blocks 12 are fixedly connected to the two vertical poles 2, a handle 13 is rotatably arranged on one side of the base 1, the handle 13 is coaxially fixedly connected to the bidirectional screw 11, a first through hole 14 is opened on the handle 13, a second through hole 15 is arranged around the handle 13 on one side of the base 1, the first through hole 14 cooperates with the second through hole 15, and a latch 16 is inserted on the first through hole 14 and the second through hole 15;

[0028] Support components 6 are provided on both sides of the bottom of the base 1, and the support components 6 include a placement screw 17 fixedly provided at the bottom of the base 1, an adjustment ring 18 is provided on the placement screw 17, the adjustment ring 18 is threadedly connected to the placement screw 17, and an anti-slip pattern 19 is provided on the adjustment ring 18, a support seat 20 is rotatably provided at the bottom of the adjustment ring 18, and a symmetrical sliding wheel 21 is fixedly provided at the bottom of the base 1;

[0029] The working principle of the utility model is as follows: first, when using the tire frame, the two bases 1 are placed horizontally on the ground at a certain interval, and then the bottom ends of the two connecting rods 23 are respectively clamped into the mounting holes 22. At this time, the guide rod 24 is extended and retracted according to the distance between the two bases 1, so that a certain limit can be set between the two bases 1. Then, according to the use requirements, the L-shaped support frame 3 is slidably clamped into the T-slot 7 through the T-block 8, and then the hydraulic telescopic rod 10 is started, and the output end of the hydraulic telescopic rod 10 is clamped into the clamping slot 9, so that the L-shaped support frame 3 is installed on the vertical pole 2. At the same time, the height of the two groups of L-shaped support frames 3 can be adjusted by the cooperation of the T-block 8 and the T-slot 7, which is suitable for the use of equipment with different heights and sizes. Then, the handle 13 is turned, and the handle 13 drives the bidirectional screw 11 to rotate, and the bidirectional screw 11 drives the two screw blocks 12 to move closer to or away from each other in the base 1, thereby driving the two vertical poles 2 to move closer to or away from each other, thereby adjusting the distance between the two vertical poles 2, so that it is suitable for the use of equipment with different widths and sizes, expanding the actual scope of application.

[0030] When it is necessary to adjust the spacing between the two bases 1, the anti-slip grooves 19 are used to drive the adjusting ring 18 to rotate, and then the adjusting ring 18 moves on the placement screw 17, and then the adjusting ring 18 drives the support seat 20 to move. When the sliding wheel 21 contacts the ground and the support seat 20 leaves the ground, the adjusting ring 18 is stopped from rotating, and then the device as a whole is moved, which is convenient for adjusting the position between the two bases 1. When it is not necessary to move, the adjusting ring 18 is driven to rotate in the opposite direction through the anti-slip grooves 19, and then the adjusting ring 18 moves on the placement screw 17, and then the adjusting ring 18 drives the support seat 20 to move. When the support seat 20 contacts the ground, the sliding wheel 21 leaves the ground, and the base 1 is placed horizontally, the adjusting ring 18 is stopped from rotating, thereby stabilizing the placement of the entire device. At the same time, it can prevent the base 1 from being placed directly on the ground, and the uneven ground affects the horizontal placement of the base 1, and then affects the horizontal placement of the device body, thereby making the device easy to tip over and affecting subsequent use.

[0031] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
