The positioning bracket 2011 is welded and set at the bottom of the substrate 1011. The positioning bracket 2011 serves the purpose of positioning.

[0024] like Figures 1 to 9 As shown, in a specific embodiment, a guide slider 2031 is installed on the synchronization plate 203, and the guide slider 2031 is slidably arranged on the surface of the lifting groove 2021. The distance between the transposition groove 2022 and the outer casing of the dual-axis stepper motor 201 is greater than the distance between the lifting groove 2021 and the outer casing of the dual-axis stepper motor 201, and the connection between the transposition groove 2022 and the lifting groove 2021 is chamfered.

[0025] like Figures 1 to 9As shown, further, a pair of slides 2041 are symmetrically installed on the fixed block 204, and a limiting rod 2042 is installed inside each pair of slides 2041, and limiting seats 2043 are installed at both ends of the limiting rod 2042. The limiting seat 2043 is welded to the bottom of the base plate 1011, and a limiting spring 2044 is sleeved on the limiting rod 2042. One end of the limiting spring 2044 is clamped on the limiting seat 2043, and the other end is clamped on the side wall of the slide 2041. During the horizontal sliding of the guide slider 2031, the synchronous plate 203 on the side wall of the guide slider 2031 slides horizontally synchronously. At this time, the connecting block 2032 on the synchronous plate 203 drives the fixed block 204 to slide horizontally, and the slide plate 2041 on the fixed block 204 slides synchronously. The slide plate 2041 slides on the surface of the limit rod 2042 at this time, and the length of the slide plate 2041 from the side wall of the limit seat 2043 changes, thereby compressing the limit spring 2044 between the two, and the limit spring 2044 is used to facilitate the subsequent resetting operation.

[0026] like Figures 1 to 9 As shown, further, each pair of lifting arms 206 is provided with a guide wheel 2061 at the end thereof, the guide wheel 2061 is oval, and the guide wheel 2061 is placed at the bottom of the base plate 1011, and a synchronization shaft 2062 is installed at the rotation center of the plurality of pairs of lifting arms 206, and both ends of the synchronization shaft 2062 are rotationally connected to the inner wall of the frame 101, and the synchronization shaft 2062 is connected to the rotation center of the rocker arm 2052.

When the fixed block 204 slides, the insertion rod 205 on the side wall of the fixed block 204 slides on both sides of the rocker arm 2052, and the sliding rod 2051 on the insertion rod 205 slides on the side wall of the strip groove 2053 of the rocker arm 2052, which can eventually push the rocker arm 2052 to swing, and the synchronization shaft 2062 on the rocker arm 2052 can rotate on the frame frame 101. The synchronization shaft 2062 can drive the jacking arm 206 to rotate downward, and the jacking arm 206 is squeezed against the ground, thereby lifting the entire equipment, thereby ensuring the overall stability of the equipment.

[0027] Embodiment 3: Based on Embodiment 2, the difference between this embodiment and the present embodiment is as follows: Figures 1 to 9As shown, a guide ring 3011 is installed at the bottom of the carrier 301. The guide ring 3011 rotates and penetrates the base plate 1011. The bottom of the guide ring 3011 is connected to the positioning gear ring 3012. The number of teeth of the positioning gear ring 3012 is the same as the number of teeth on the half gear 3013. A positioning shaft 3014 is installed at the center of the bottom of the carrier 301. The bottom of the positioning shaft 3014 is connected to the base plate 1011. As the guide roller 202 rotates, the half gear 3013 on the side wall of the guide roller 202 drives the positioning gear ring 3012 to rotate, and then the guide ring 3011 connected to the positioning gear ring 3012 rotates, and the guide ring 3011 drives the carrier 301 to rotate. The carrier 301 rotates on the positioning shaft 3014, and the angle of the inflation and exhaust assembly 400 installed on the carrier 301 changes, thereby achieving the purpose of adjusting the position of the inflation and exhaust assembly 400.

[0028] like Figures 1 to 9 As shown, in a specific embodiment, a through slot 3023 is provided on the base plate 1011, the through slot 3023 and the unlocking slot 303 are located on the same plane, and the unlocking slot 303 and the through slot 3023 are adapted to each other in specifications, the synchronization rod 3021 movably passes through the through slot 3023, and a guide rod 3022 is movably installed inside the synchronization rod 3021, and both ends of the guide rod 3022 are respectively connected to the side walls of the through slot 3023. The guide rod 3022 and the through slot 3023 ensure that the connected synchronization rod 3021 can only slide horizontally.

[0029] The implementation principle of a movable automatic filling and discharging system of the present invention is as follows: When the equipment moves to the approximate position, the operator first starts the dual-axis stepper motor 201, and drives the guide rollers 202 on both sides to rotate on both sides of the connecting seat 2012 through the dual-axis stepper motor 201. A combination groove is provided on the connecting seat 2012. At this time, the lifting groove 2021 and the transposition groove 2022 in the combination groove rotate synchronously. When the lifting groove 2021 rotates, the lifting groove 2021 can drive the guide slider 2031 to slide horizontally. When the guide slider 2031 slides to the surface of the transposition groove 2022, the half gear 3013 on the guide roller 202 is just meshed with the positioning gear ring 3012.

[0030] During the horizontal sliding of the guide slider 2031, the synchronous plate 203 on the side wall of the guide slider 2031 slides horizontally synchronously. At this time, the connecting block 2032 on the synchronous plate 203 drives the fixed block 204 to slide horizontally, and the slide plate 2041 on the fixed block 204 slides synchronously. The slide plate 2041 slides on the surface of the limit rod 2042 at this time, and the length of the slide plate 2041 from the side wall of the limit seat 2043 changes, thereby compressing the limit spring 2044 between the two, and the limit spring 2044 is used to facilitate the subsequent resetting operation.

[0031] When the fixed block 204 slides, the insertion rod 205 on the side wall of the fixed block 204 slides on both sides of the rocker arm 2052, and the sliding rod 2051 on the insertion rod 205 slides on the side wall of the strip groove 2053 of the rocker arm 2052, which can eventually push the rocker arm 2052 to swing, and the synchronous shaft 2062 on the rocker arm 2052 can rotate on the frame frame 101. The synchronous shaft 2062 can drive the jacking arm 206 to rotate downward, and the jacking arm 206 is squeezed against the ground, thereby lifting the entire equipment, thereby ensuring the overall stability of the equipment.

[0032] During the horizontal sliding of the synchronization plate 203, the circular frame 302 on the synchronization plate 203 slides on the side wall of the guide roller 202, and the synchronization rod 3021 on the circular frame 302 slides in the through groove 3023 at this time. The synchronization rod 3021 slides along the guide rod 3022 passing through it to achieve the purpose of guidance, and the top of the synchronization rod 3021 finally slides along the unlocking groove 303, and can finally slide into the annular groove 3031, that is, the limit of the support platform 301 is unlocked.

[0033] When the guide slider 2031 slides to the transposition groove 2022, the half gear 3013 and the positioning gear ring 3012 are meshed, and as the guide roller 202 continues to rotate, the above-mentioned lifting and unlocking operations are stopped synchronously. However, as the guide roller 202 rotates, the half gear 3013 on the side wall of the guide roller 202 drives the positioning gear ring 3012 to rotate, and then the guide ring 3011 connected to the positioning gear ring 3012 rotates, and the guide ring 3011 drives the support platform 301 to rotate, and the support platform 301 rotates on the positioning shaft 3014, and the angle of the inflation and exhaust assembly 400 installed on the support platform 301 changes, thereby achieving the purpose of adjusting the position of the inflation and exhaust assembly 400.

[0034] At this time, the operator starts the inflation and exhaust component 400. The inflation and exhaust component 400 is a prior art, and its working principle will not be described in detail here.
