[0023] An L-shaped support plate 9 is horizontally fixed directly below the fixed plate 8. A circular linkage disk 15 is horizontally placed directly below each threaded hole 10 between the support plate 9 and the fixed plate 8. Connecting rods 24 are fixed to the upper and lower sides of the linkage disk 15, respectively. A through hole 12 is provided on the linkage disk 15, the purpose of which is to facilitate ventilation and drainage. The two adjacent groups of linkage disks 15 are connected by a connecting plate 23. The front and rear ends of the connecting plate 23 are respectively rotatably connected to the connecting rods 24 on the two adjacent groups of linkage disks 15. It should be noted that in this embodiment, several groups The linkage disk 15 is placed along the length and width direction of the support plate 9, the connecting plate 23 above the linkage disk 15 is placed along the length direction of the support plate 9, and the connecting plate 23 below the linkage disk 15 is placed along the width direction of the support plate 9. The purpose is to enable a plurality of groups of linkage disks 15 to have linkage connections. An annular guide groove 13 is provided on the support plate 9 directly below each threaded hole 10. The connecting rod 24 located at the lower side of the linkage disk 15 is slidably connected to the guide groove 13. The purpose is to be used to connect the linkage disk 15 with the support plate 9 The connecting support guides the rotation trajectory of the linkage disk 15. A plurality of through holes 14 are provided on the support plate 9 for the purpose of facilitating ventilation and drainage. A circular placement disk 16 is horizontally fixed to the upper end of the connecting rod 24 on the upper side of the linkage disk 15. A hollow fixed cylinder 21 is vertically fixed to the middle of the upper side of the placement disk 16. An extension cylinder 20 is vertically slid on the fixed cylinder 21. The lower side of the extension cylinder 20 is connected to the bottom side of the inner wall of the fixed cylinder 21 through a telescopic spring 26. An insertion rod 19 is fixed to the upper side of the extension cylinder 20. The lower end of the test tube column 6 is provided with a plug rod 19. The rod 19 is plugged into the positioning hole 25, and a driven wheel 22 is arranged on the upper side of one group of placement plates 16.
