[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figures 1 to 4 shown, the present invention provides an adjustable new type of quick gun head insertion device, including a fixed frame 1. A cover plate 2 is attached to the upper surface of the fixed frame 1 to enclose the cover plate 2 above the fixed frame 1 for sealing. The inside of the fixed frame 1 further includes an adjusting cord assembly 3;

[0028] The adjusting cord assembly 3 includes a track lock block 34 slidably arranged inside the guide grooves on both sides of the fixed frame 1. A limit shaft 35 is fixedly arranged at the middle position between the two track lock blocks 34. A jack 36 is opened at the middle position of the limit shaft 35. A cord 33 passes through the inside of the jack 36. The cord 33 passes through the jack 36 of the limit shaft 35 to form a traction structure, adjusting the interval distance between adjacent cords 33 to screen different pipette gun heads. A limit rod 11 is inserted into one side of the bottom end of the fixed frame 1, and the limit rod 11 is in contact with the lower movable buckle 37, so as to facilitate the extraction of the limit rod 11 structure and open the lower notch, and the gun head between the cords 33 can be removed.

[0029] Specifically, a housing 31 is fixedly arranged at a corner of the fixed frame 1. A torsion spring shaft 32 is rotatably arranged at the top end of the housing 31, and the torsion spring shaft 32 passes through the housing 31 and is rotatably arranged therewith. The cord 33 is wound around the torsion spring shaft 32. A movable buckle 37 is fixedly arranged on the outer side of the track lock block 34, and the movable buckle 37 is located outside the fixed frame 1. By rotating the torsion spring shaft 32 inside the housing 31, the cord 33 is driven to be wound around the outer side of the torsion spring shaft 32 for winding and restraint.

[0030] Further, the fixed frame 1 is set as a slidable two - half structure. At one end of the fixed frame 1 adjacent to the other fixed frame 1 on one side, a connecting block 5 is fixedly arranged, and the connecting block 5 is slidably arranged inside the slot of the fixed frame 1 on the other side. A telescopic frame 6 is rotatably arranged on the outer side of the connecting block 5. An elastic sheet 8 is fixedly arranged at the middle position between the two telescopic frames 6. An anti - slide block 7 is attached to the side of the telescopic frame 6 close to the inner wall of the slot of the fixed frame 1, and the anti - slide block 7 is set as a rubber semi - circular block. By stretching the two fixed frames 1 to expand, a larger accommodating space is formed after opening, and the two fixed frames 1 are kept stable in the expanded state through the docking of the telescopic frames 6.

[0031] It is worth noting that positioning holes are respectively opened at the four corners of the side of the cover plate 2 close to the fixed frame 1. A positioning head 4 is magnetically attracted and arranged inside the positioning holes of the cover plate 2, and the positioning head 4 is fixedly arranged with the fixed frame 1. A separating fork 10 is attached to the bottom of the fixed frame 1. A clamping plate 9 is inserted into the left - hand side interior of the separating fork 10, and the clamping plate 9 is attached to the left side of the fixed frame 1. The cover plate 2 is covered on the upper opening of the fixed frame 1 for closing. At the end of sorting, the clamping plate 9 and the separating fork 10 are inserted into the bottom of the fixed frame 1 to separate the gun heads. A row of slots is opened at the connection between the clamping plate 9 and the separating fork 10.

[0032] Among them, the fixed frame 1 and the cord 33 are prior arts and will not be elaborated here; meanwhile, the present utility model also includes a power source, a controller, a switch, etc., which are not the main technical points of this patent and will not be elaborated here.

[0033] Working principle and process:

[0034] According to the size of the pipette tip to be inserted as required by the operator, the operator moves the track locking block 34 inside the guide groove of the fixed frame 1, and moves the structure of the track locking block 34 and the limiting shaft 35 between them to a position closer to or farther from each other, so as to control the adjustment of the distance of the cord 33 passing through the inside of the limiting shaft 35, complete the adjustment operation of the tip limiting gap, and put the pipette tip of the same batch of tip sizes into the inside of the fixed frame 1. According to the number of pipette tips to be inserted, the operator stretches the two sides of the fixed frame 1, and through the connecting block 5 structure of one side of the fixed frame 1, controls the outer telescopic frame 6 to be pulled out from the slot inside the fixed frame 1. After unfolding, a fixed frame 1 with a larger accommodation space is formed, and the elastic piece 8 is used to push the telescopic frame 6 to unfold, and the anti-slip block 7 is pressed against the inner wall of the slot of the fixed frame 1 for anti-slip operation to maintain the opened state. At the same time, the torsion spring shaft 32 inside the outer shell 31 rotates, traction the outer cord 33, and pulls it open through the jack 36 of the limiting shaft 35. After putting the pipette tip in, cover the cover plate 2 outside the positioning head 4, and then pour the tips into the cover of the fixed frame 1 and shake gently until all the tips are stuck in the gap of the cord 33. After shaking and approaching, the dividing fork 10 located below can be horizontally inserted under the fixed frame 1 to separate the tips. After the separation interval, at the same time, according to the number of sorted tips, different numbers of dividing forks 10 can be inserted into the corresponding slots for horizontal sorting adjustment. After inserting the tips into the corresponding 96-well tip box, the bottom limiting rod 11 structure of the fixed frame 1 can be pulled out, and the tips can be withdrawn from the inside of the fixed frame 1 in sequence.
