The two curved clamping plates 203 are both in contact with the outer wall of the tank body 4. A bottom block 2018 is arranged below the curved support plate 202. The top of the bottom block 2018 is provided with a bottom block 2018. The top of the movable column 2016 passes through the arc support plate 202 and is rotatably connected to the support column 2013. The top of the support column 2013 is fixed to the bottom of the arc clamping plate 203, and the movable column 2016 is movably connected to the arc support plate 202. A spring 2017 is fixedly connected between the bottom block 2018 and the arc support plate 202. The spring 2017 is sleeved on the outside of the movable column 2016. A screw 209 is fixedly installed on the top of the arc support plate 202. The arc clamping plate 203 is sleeved on the outside of the screw 209. The arc clamping plate 203 A nut 2010 is provided at the top, and the nut 2010 is threadedly sleeved on the outer side of the screw rod 209. A positioning column 2012 is fixedly installed at the bottom of the arc clamping plate 203. A positioning cylinder 2015 is fixedly installed on the top of the arc support plate 202. The inner diameter value of the positioning cylinder 2015 is equal to the outer diameter value of the positioning column 2012. A limiting rod 2011 is fixedly installed on the top of the arc support plate 202. A limiting groove 2014 is provided on the outer side of the movable column 2016.

Two slide plates 207 are symmetrically threadedly sleeved on the outer side of the bidirectional screw rod 208. L-shaped seats 205 are fixedly installed on the sides of the two slide plates 207 away from each other. The two L-shaped seats 205 are respectively fixed to the bottom of the two arc-shaped support plates 202, and the two L-shaped seats 205 both penetrate the U-shaped frame 201 and are movably connected to the U-shaped frame 201. Support wheels 206 are fixedly installed on the bottom of the two L-shaped seats 205, and the two support wheels 206 are both located on the top of the base 1;

[0025] When in use, first rotate the bidirectional screw rod 208, and respectively drive the two L-shaped seats 205 to move through the two slide plates 207, and drive the two arc-shaped support plates 202 to move, so as to adjust the distance between the two arc-shaped support plates 202 according to the size of the tank body 4, and then place the tank body 4 on the arc-shaped placement plate 204 and the two arc-shaped support plates 202, and then move the arc-shaped clamping plate 203 upward to drive the movable column 2016 to move vertically upward, so that the positioning column 2012 originally located in the positioning cylinder 2015 moves upward, and the spring 2017 is compressed.

The tooth plate 305 is located below the bidirectional screw rod 208. A gear 302 is fixedly installed in the middle of the outside of the bidirectional screw rod 208. The gear 302 is meshed and connected with the tooth plate 305. A screw rod 303 is provided below the guide rod 306. The screw rod 303 is arranged parallel to the guide rod 306. One end of the screw rod 303 is rotatably connected to one of the L-shaped frames 301, and the other end of the screw rod 303 passes through the other L-shaped frame 301 and is fixedly installed with a turntable 307. The outer side of the screw rod 303 is threadedly sleeved with a screw sleeve 304, and the screw sleeve 304 is fixed to the bottom of the tooth plate 305.

[0027] When in use, first rotate the turntable 307 to drive the rotation of the screw rod 303, and drive the tooth plate 305 to slide along the guide rod 306 through the screw sleeve 304. Since the tooth plate 305 is meshed with the gear 302, the rotation of the bidirectional screw rod 208 is finally realized, which is convenient for adjusting the distance between the two arc-shaped support plates 202.
