At this time, the slide block 6 slides on the slide bar 14 to assist the propulsion platform 5 to move. The propulsion platform 5 is used to drive the support column 11 to move, so that the top frame 22 on the support column 11 and the bracket 16 can extend into the interior of the mixing tank 36.
[0025] A rod frame 15 is fixedly installed at the end of the sliding rod 14, and the rod frame 15 plays a role of fixing the sliding rod 14.

The moving rod 13 drives the No. 1 gear plate 18 to move, and then drives the No. 1 gear 17 to rotate, so that the multiple top frames 22 on the support column 11 rotate synchronously to make it stand up. In this process, the bracket 16 is hindered by the wall of the mixing tank 36 and flipped, so that the bracket 16 adjusts itself to an inclined state and fits against the inner wall of the mixing tank 36 for support.
[0029] The flipping and resetting member includes a No. 2 groove seat 33 fixedly mounted on the middle part of the lower end of the bracket 16, and the other end of the top frame 22 is located inside the No. 2 groove seat 33.

The other end of the top frame 22 is rotatably mounted on the outer surface of the No. 2 connecting shaft 32. The No. 2 connecting shaft 32 plays a connecting role. One end of the No. 2 connecting shaft 32 is coaxially inlaid with the No. 2 gear 31. The front end of the top frame 22 is elastically mounted with a No. 2 tooth plate 27. The No. 2 tooth plate 27 is meshed with the No. 2 gear 31. The No. 2 tooth plate 27 and the No. 2 gear 31 play a role in flipping and resetting the bracket 16.
[0030] A bearing frame 30 is fixedly installed at the front end of the top frame 22, and an directional column 23 is fixedly installed between the upper and lower end surfaces of the bearing frame 30. The bearing frame 30 supports the directional column 23. A sliding sleeve 24 is slidably fitted on the outer surface of the directional column 23. The directional column 23 guides the sliding sleeve 24. A spring body 29 is wound around the outer side of the directional column 23. One end of the spring body 29 is fixed to the inner bottom surface of the bearing frame 30. The spring body 29 pushes the sliding sleeve 24, and the other end of the spring body 29 is fixed to the lower end of the sliding sleeve 24. Two positioning ears 25 are symmetrically fixedly installed on the outer surface of the sliding sleeve 24. The sliding sleeve 24 and the positioning ears 25 are integrally formed. Positioning grooves 28 are penetrated on both sides of the bearing frame 30. The positioning ears 25 and the positioning grooves 28 limit the flipping angle of the bracket 16. The positioning ears 25 pass through the inside of the positioning grooves 28, and the positioning ears 25 and the positioning grooves 28 are slidably matched. A fixing frame 26 is fixedly installed on the end of one of the positioning ears 25. The fixing frame 26 fixes the No. 2 tooth plate 27, and the end of the fixing frame 26 is fixed to the No. 2 tooth plate 27.
[0031] When in use, the servo motor 2 works to drive the threaded rod 3 to rotate, so that the pushing platform 5 threadedly connected to the threaded rod 3 can move. At this time, the slider 6 slides on the slide rod 14 to assist the pushing platform 5 to move, and the pushing platform 5 is used to drive the support column 11 to move, so that the top frame 22 on the support column 11 and the bracket 16 can extend into the interior of the mixing tank 36. At this time, the limit plate 12 is inserted into the tank mouth of the mixing tank 36, and then the servo push cylinder 8 works to drive the moving rod 13 to slide in the support column 11, and the moving rod 13 is used to drive the No. 1 gear plate 18 to move, and then drive the No. 1 gear 17 to rotate, so that the multiple top frames 22 on the support column 11 rotate synchronously to make it stand up. In this process, the bracket 16 is hindered by the wall of the mixing tank 36 and flips over, so that the bracket 16 adjusts itself to an inclined state and fits the inner wall of the mixing tank 36 for support. At the same time, the bracket 16 will drive the No. 2 gear 31 to rotate during the flipping process, so that the No. 2 gear The plate 27 moves downward, the sleeve 24 slides on the directional column 23, and the spring body 29 contracts and deforms, and then the screws on the mixing tank 36 can be loosened, the tank mouth of the mixing tank 36 can be disassembled, and then the push platform 5 moves in the opposite direction to remove the tank mouth of the disassembled mixing tank 36, and then the interior of the mixing tank 36 can be inspected. When the inspection is completed and the mixing tank 36 is assembled, if the manipulator needs to be taken out of the mixing tank 36, the servo push cylinder 8 can drive the moving rod 13 to move in the opposite direction, and then drive the erected top frame 22 to rotate to a horizontal state. At this time, the contracted spring body 29 recovers its deformation to push the sleeve 24, and at the same time the positioning ear 25 slides in the positioning groove 28, driving the No. 2 tooth plate 27 to move, and then driving the No. 2 gear 31 to rotate, so that the inclined bracket 16 can reset itself, that is, flip to a horizontal state, reducing the space occupied by the manipulator, and then it can be taken out.
