[0027] Preferably, the linear drive is an air cylinder 5.

[0028] It is worth noting that the top end of the inclined plate 6 can also be a slope gradually decreasing away from the air cylinder 5, that is, the top end of the inclined plate 6 is a slope uniformly rising along the moving direction of the output end of the air cylinder 5.

[0029] When the support blocks 8 are located at the lowest end of the limiting grooves 21, the top end of the outer support 4 and the horizontal jack 1 is not higher than the wheel 3.

[0030] A plurality of guide rails II 14 are installed between the outer wall of the inner support frame 2 and the inner wall of the outer support 4, and the length direction of the guide rails II 14 is vertical.

[0031] A movement stabilizing assembly is installed between the inner support frame 2 and the outer support 4, the movement stabilizing assembly comprises a rack 15 installed on the outer support 4 near the handshaking end of the horizontal jack 1, corresponding symmetrical gears 16 are rotatably installed on the outer wall of the inner support frame 2, and the rack 15 and the gears 16 are meshingly connected.

[0032] Preferably, a blocking tooth plate 17 is also slidingly installed on the inner support frame 2, the blocking tooth plate 17 is provided with a limiting hole 19 through the inner support frame 2 near one side of the horizontal jack 1, a pull rod 18 is slidingly installed on the inner support frame 2 near one side of the horizontal jack 1, the pull rod 18 passes through the limiting hole 19, and a limiting rod 20 which can pass through the limiting hole 19 is installed on the pull rod 18.

[0033] Preferably, the limiting hole 19 and the limiting rod 20 are both rhombic.

[0034] When the cylinder 5 pushes the inclined plate 6 to slide, the inner support frame 2 drives the gear 16 to lift, and the gear 16 is engaged with the rack 15; when the inclined plate 6 is stationary, the gear 16 is stationary, the blocking tooth plate 17 is pulled outward to make the blocking tooth plate 17 engaged with the gear 16 while the limiting rod 20 passes through the limiting hole 19, the limiting hole 19 is located between the limiting rod 20 and the inner support frame 2, the limiting rod 20 is rotated to form an angle with the limiting hole 19 by rotating the pull rod 18, and the limiting rod 20 limits the blocking tooth plate 17.

[0037] Working principle: when the inner support frame 2 is at the lowest point of the inclined plate 6, the horizontal jack 1, the wheel 3 and the outer support 4 are all lower than the chassis of the sports car, so that the jack is suitable for sports cars, when the height needs to be adjusted, the cylinder 5 is started, the cylinder 5 pushes the inclined plate 6 to slide along the guide rail one 7, because the guide rail two 14 makes the inner support frame 2 can only slide in the vertical direction, so the inclined plate 6 pushes the inner support frame 2 to rise through the supporting block 8, at the same time, the gear 16 is engaged with the rack 15, when it is raised to the appropriate height, the cylinder 5 stops, the blocking tooth plate 17 is pulled outward to make the blocking tooth plate 17 block the gear 16 from continuing to rotate, the limiting rod 20 passes through the limiting hole 19, the rotating pull rod 18 drives the limiting rod 20 to rotate and limit the blocking tooth plate 17, the inclined plate 6 hooks the lifting inclined plate 10 through the T-shaped rails 13, when the inclined plate 6 slides, it pushes the lifting inclined plate 10 to slide downwards along the guide rail one 12, the lifting inclined plate 12 drives the support plate 11 to support the ground, so that the device is more stable.
