A placement hole 301 and at least one clamping hole 302 are provided on the upper surface of the basic workbench 3 corresponding to the clamping block, and rubber pads are embedded on the hole walls of the placement hole 301 and the clamping hole 302 to enhance the friction force of the clamping block when the clamping block is clamped into the placement hole 301 or the clamping hole 302, and the clamping block can move freely in the placement hole 301 to enhance the stability during clamping.

[0022] In a specific implementation, the two bracket bodies may be symmetrically distributed about the connecting assembly.

[0023] In a specific implementation, the two bracket bodies can be arranged parallel to each other, and the central axes of the corresponding placement grooves 601 on the upper plates 6 of the two bracket bodies are arranged on the same straight line to ensure the effective placement of the pipette.

[0024] In a specific implementation, the connecting assembly can be an X-shaped structure, which includes a first connecting rod 401, a second connecting rod 402 and a connecting shaft 403. The first connecting rod 401 and the second connecting rod 402 are cross-distributed, and the connecting shaft 403 is arranged at the intersection and overlap of the first connecting rod 401 and the second connecting rod 402. Both side ends of the first connecting rod 401 and both side ends of the second connecting rod 402 are inserted into the gap 2. One end of the first connecting rod 401 is hinged to the base 1 and / or the basic workbench 3 on the first bracket body, and the other end of the first connecting rod 401 is movably connected to the base 1 and / or the basic workbench 3 on the second bracket body (such as: the base on the second bracket body A sliding track groove 303 is arranged on the workbench 3, and a slider 404 is arranged on the other end of the first connecting rod 401, and the slider 404 passes through the sliding track groove 303 and can slide along the sliding track groove 303); one end of the second connecting rod 402 is hinged to the base 1 and / or the basic workbench 3 on the second bracket body, and the other end of the second connecting rod 402 is movably connected to the base 1 and / or the basic workbench 3 on the first bracket body (for example: a sliding track groove 303 is arranged on the basic workbench 3 on the first bracket body, and a slider 404 is arranged on the other end of the second connecting rod 402, and the slider 404 passes through the sliding track groove 303 and can slide along the sliding track groove 303).

[0025] In specific implementation, the rotating and fixing mechanism can directly select the existing connection structure on the market that can realize the folding and fixing of the plate 6 on the main support, and the reverse folding and resetting function. Figures 1 to 4The rotating fixing mechanism shown in the figure comprises a hinge 9, a positioning pin 8, a first positioning hole 504 and a second positioning hole 502 arranged on the rotating worktable 5, and a positioning groove 603 and a third positioning hole 602 arranged on one end surface of the plate 6. Compared with the plate 6, the first positioning hole and the second positioning hole 502 are arranged on the same side. The first positioning hole 504 is matched with the positioning groove 603, the second positioning hole 502 is matched with the third positioning hole 602, and the first positioning hole 504, the second positioning hole 502, the positioning groove 603 and the third positioning hole 602 are all set for the positioning pin 8. One or more hinges 9 are set between the plate 6 and the rotating table 5 to realize the rotatable connection between the plate 6 and the rotating table 5. The part of the hinge 9 connected with the plate 6 can avoid the positioning groove 603, the third positioning hole 602 and the placement groove 601, and the part of the hinge 9 connected with the rotating table 5 can avoid the connection groove 501, the first positioning hole 504 and the second positioning hole 502. The upper surface of the rotating table 5 on the other side of the plate 6 is protruded, and the protruded surface and the first positioning hole are respectively set on both sides of the plate 6. When the plate 6 is flipped into position (standing upright), one end face of the plate 6 contacts the protruding portion of the rotating table 5 to form a preliminary positioning to prevent the plate 6 from rotating excessively; and at this time, the central axis of the positioning groove 603 coincides with the central axis of the first positioning hole.

[0026] In a specific implementation, the cross section of the positioning pin 8 in the vertical direction is L-shaped.

[0027] The working principle of the above-mentioned foldable pipette stand can be:

[0028] To unfold the foldable pipette rack, pull one or two bracket bodies so that the end of the first connecting rod 401 and the end of the second connecting rod 402 in the same bracket body between the bracket bodies move toward each other to shorten the distance, thereby expanding the distance between the two bracket bodies so that the foldable pipette rack can be unfolded in the horizontal direction. When the bracket body is unfolded to the desired position, stop pulling the bracket body, and then rotate the rotating workbench 5 on the bracket body to move the rotating workbench 5 to the desired height, insert the block at the lower end of the support member 7 connected to the bottom of the rotating workbench 5 into the corresponding card hole 302, and finally rotate the plate 6 to make the plate 6 vertical. At this time, one side end surface of the plate 6 is in contact with the protruding part 503 of the rotating workbench 5, and the first positioning hole 504 on the other side of the plate 6 is connected to the positioning groove 603 to form a positioning hole member when unfolded, and insert the positioning pin 8 into the positioning hole member when unfolded, and fix the plate 6 by the positioning pin 8 (such as: forming a Figure 1The structure shown in the figure prevents the plate 6 from rotating in the opposite direction to restore the initial position. Repeat this step to unfold the rotating table 5 and the plate 6 on the foldable pipette rack. Then, the placement grooves 601 on all the plates 6 in the foldable pipette rack can be used to place the pipette, that is, the two side ends of the pipette can be placed in the placement grooves 601 on different bracket bodies respectively to form a stable placement effect.

[0029] Close the folding pipette stand and combine Figure 1-Figure 3 As shown in the figure, pull out the positioning pin 8 inserted into the positioning hole when unfolding. Figure 4 The content shown in the figure is rotated in the reverse direction (rotated in the direction of the second positioning hole 502, i.e., in the direction of the Figure 4 The plate 6 is rotated in the direction indicated by the middle arrow 1.1 to restore the plate 6 to its initial position. At this time, the second positioning hole 502 is connected with the third positioning hole 602 to form a hole for fixing the plate 6. The positioning pin 8 is inserted into the hole (the positioning pin 8 is along the Figure 4 Insert in the direction indicated by the middle arrow 1.2, the locating pin 8 and the hole piece can be detachably connected by using threads or blocks), and the locating pin 8 is used to fix the plate 6 on the rotating table 5 to prevent the plate 6 from flipping over at will when not in use, and at the same time, the locating pin 8 can be effectively stored to prevent it from falling. Then release the connection between the block at the lower end of the support 7 and the corresponding hole 302, and rotate the rotating table 5 to fall to the initial position. At this time, the block at the lower end of the support 7 is connected to the placement hole 301 to form a preliminary fixation. Repeat the above operation until all the plates 6 and the rotating table 5 are restored to the initial position, and then push the bracket body in the direction of the other bracket body. At this time, the end of the first connecting rod 401 and the end of the second connecting rod 402 in the same bracket body move back to back to expand the distance, the distance between the two bracket bodies is reduced, and the two bracket bodies are closed to the initial position.

[0030] The above-mentioned matters can be achieved by using existing technologies, so they will not be elaborated here.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several similar modifications and improvements without departing from the inventive concept of the present invention, and these should also be regarded as within the protection scope of the present invention.
