[0028] The end surface of the worm 52 is provided with a hexagonal groove.

[0029] A second rod 11 is provided on the support member 1; the worm 52 is passed through the second rod 11; a slot 12 is provided on the second rod 11; a limiting rod 6 is rotatably connected to the worm 52; a plurality of slots 12 are provided in a circular array; when the limiting rod 6 is inserted into the slot 12, the worm 52 is stationary and the seat cushion 3 maintains the current height; when adjustment is required, the limiting rod 6 is moved out of the slot 12 and then the worm 52 is rotated by the hexagonal bolt, thereby driving the seat cushion 3 to move up and down.

[0030] The support member 1 is arranged on the vehicle body, and an adjusting rod 2 is slidably connected to the support member 1. The adjusting rod 2 controls the seat cushion 3 to move up and down and supports the seat cushion 3. The seat cushion 3 is arranged on the top of the adjusting rod 2, and a guide strip 21 is arranged on the side wall of the adjusting rod 2. The guide strip 21 is penetrated by the support member 1. The guide strip 21 prevents the direction of the seat cushion 3 from being deviated when the height of the seat cushion 3 is adjusted up and down, so that there is an angular deviation between the driver and the seat cushion 3. A first rod 4 is rotatably connected inside the support member 1. The first rod 4 is a threaded rod. The first rod 4 is threadedly penetrated by the adjusting rod 2. A worm gear 51 is fixedly connected to the bottom of the first rod 4. A worm 52 is rotatably connected to the bottom of the support member 1. The worm 52 meshes with the worm gear 51. The worm 52 can drive the worm gear 51 to rotate, but the worm gear 51 cannot cause the worm 52 to rotate. Therefore, when the user is on the seat cushion 3, the height of the seat cushion 3 will not deviate. A scale 22 is opened on the side wall of the adjusting rod 2. There are several scales 22 along the adjustment rod 2, and the scales 22 show the current height of the seat cushion 3 from the support member 1 and are converted into a size number suitable for a group of people of a certain height. A hexagonal groove is provided on the end surface of the worm 52, and the hexagonal groove can be adapted to the hexagonal wrench currently on the market. A second rod 11 is provided on the support member 1, and the second rod 11 is coaxial with the worm 52. The worm 52 is penetrated by the second rod 11, and a slot 12 is provided on the side wall of the second rod 11. The worm 52 is rotatably connected to the limit rod 6, and the limit rod 6 can be retracted into the worm 52 when not in use. The limit rod 6 corresponds to the slot 12. Several groups of slots 12 are provided along the second rod 11, and the slots 12 are all located at different angles. When the limit rod 6 is inserted into the slot 12, the worm 52 is stationary and the seat cushion 3 maintains the current height; when adjustment is required, the limit rod 6 is moved out of the slot 12 and then the worm 52 is rotated by the hexagonal bolt, thereby driving the seat cushion 3 to move up and down.

[0031] The support member 1 is arranged on the vehicle body, and an adjusting rod 2 is slidably connected to the support member 1. The adjusting rod 2 controls the seat cushion 3 to move up and down and supports the seat cushion 3. The seat cushion 3 is arranged on the top of the adjusting rod 2, and a guide strip 21 is arranged on the side wall of the adjusting rod 2. The guide strip 21 is penetrated by the support member 1. The guide strip 21 prevents the direction of the seat cushion 3 from being deviated when the height of the seat cushion 3 is adjusted up and down, so that there is an angular deviation between the driver and the seat cushion 3. A first rod 4 is rotatably connected inside the support member 1. The first rod 4 is a threaded rod. The first rod 4 is threadedly penetrated by the adjusting rod 2. A worm gear 51 is fixedly connected to the bottom of the first rod 4. A worm 52 is rotatably connected to the bottom of the support member 1. The worm 52 meshes with the worm gear 51. The worm 52 can drive the worm gear 51 to rotate, but the worm gear 51 cannot cause the worm 52 to rotate. Therefore, when the user is on the seat cushion 3, the height of the seat cushion 3 will not deviate. A scale 22 is opened on the side wall of the adjusting rod 2. The scale 22 is opened along the adjusting rod 2 There are several, the scale 22 shows the current height of the seat cushion 3 from the support member 1 and is converted into a size number suitable for a certain height group of people, a hexagonal slot is provided on the end surface of the worm 52, the hexagonal slot can be adapted to the hexagonal wrench currently on the market, the support member 1 is provided with a second rod 11, the second rod 11 is coaxial with the worm 52, the worm 52 is penetrated by the second rod 11, a slot 12 is provided on the side wall of the second rod 11, the worm 52 is rotatably connected to the limit rod 6, and the limit rod 6 can be used when not in use To retract the worm 52, the limit rod 6 corresponds to the slot 12. The slot 12 is provided in several groups along the second rod 11 and the slots 12 are located at different angles. When the limit rod 6 is inserted into the slot 12, the worm 52 is stationary and the seat cushion 3 maintains the current height. When adjustment is required, the limit rod 6 is moved out of the slot 12 and then the worm 52 is rotated by the hexagonal bolt, thereby driving the seat cushion 3 to move up and down, thereby realizing the rapid and precise adjustment of the height of the seat cushion 3.
