When the vehicle moves forward, because the middle connecting pipes 101-6 and 102-5 of the first shaft rods of the two sets of ground grabbing mechanisms are respectively in close contact with the outer sides of the front and rear parts of the lower ends of the wheels 2, the lower parts of the outer tyres of the wheels 2 can drive the shaft rods 101-4 and 102-3 of the two sets of ground grabbing mechanisms to rotate, the driving gears 101-1 and 102-1 of the two sets of ground grabbing mechanisms rotate along with the rotation, the driven gears 101-2 and 102-2 of the two sets of ground grabbing mechanisms are respectively driven by the driven gears 101-2 and 102-2 of the two sets of ground grabbing mechanisms to rotate, the ground grabbing wheels 101-5 and 102-4 of the two sets of ground grabbing mechanisms rotate anticlockwise, after the wheels 101-5 and 102-4 rotate in accordance with the steering direction of the wheels 2, as a plurality of toothed protruding rods 101-8 and 102-7 are welded on the outer surfaces of the annular wheels 101-5 and 102-4 at a certain distance, the lower ends of the wheels 101-5 and 102-4 of the two sets of ground grabbing mechanisms are contacted with the ground, and the other parts of the wheels are spaced at a certain distance (about 8 cm) from the ground, so that the wheels 101-5 and 102-4 with the toothed protrusions can effectively contact with the snow ground and enter the lower ends of snow and the like, thereby improving the passing performance of the wheels, ensuring that the vehicle can safely run on the snow ground and the like, and reducing traffic accidents. In practical application, when the two driving gears 101-1 of the first set of ground grabbing mechanism are driven by the wheels 2 to rotate clockwise, the two driving gears 101-1 respectively drive the two following gears 101-3 to rotate clockwise, the two following gears 101-3 respectively drive the two straight toothed plates 302-5 at the upper parts of the left lower ends of the two rectangular sleeves of the second set of connecting brackets to move forwards, the distance between the front inner ends and the rear inner ends of the first shaft rod middle connecting pipes 101-6 and 102-5 of the two sets of ground grabbing mechanisms is smaller than the length of the contact parts between the front inner ends and the rear inner ends of the lower parts of the wheels 2, so that the tight contact between the front outer sides and the rear outer sides of the first shaft rod middle connecting pipes 101-6 and 102-5 of the two sets of ground grabbing mechanisms and the front outer sides and rear outer sides of the wheels 2 can be effectively ensured, and the power of the wheels is effectively transmitted to the first shaft rod middle connecting pipes 101-6 and 102-5 of the two sets of ground grabbing mechanisms. When the connecting bracket is used and needs to be disassembled, an operator presses the upper end of the middle part of the rectangular sleeve at the front end of the first set of connecting bracket by hand/>Rear upper end of movable clamping plate 301-6, upper end of middle part of rectangular sleeveThe rear end of the movable clamping plate 301-6 moves downwards against the elastic force of the spring 301-7, the front part moves upwards, and the upper end/>, at the middle part, of the rectangular sleeve pipeThe front lower part of the movable clamping plate 301-6 and the middle section of the helical tooth groove 302-6 in the middle of the front end of the rectangular sleeve of the second set of connecting brackets are separated from each other, and are not clamped into the middle section of the helical tooth groove 302-6 in the middle of the upper end of the rectangular sleeve any more, so that an operator can pull out the two rectangular sleeves 302-2 of the second set of connecting brackets from the two rectangular sleeves 301-2 of the first set of connecting brackets by slightly exerting force on the rear side, and the purpose of disassembly is achieved. The disassembled parts are placed in a trunk and the like in the vehicle. The invention is used for a plurality of sets, and a plurality of wheels are respectively installed and have better passing performance. 4 is the ground. After the support frame 5 and the sliding wheels 6 are in a vertical state, the wheels can contact the rear sides of the front sliding wheels 6 when moving forwards too much, the wheels can contact the front sides of the rear sliding wheels 6 when moving backwards too much, and the sliding wheels 6 play a role in positioning the wheels.
