Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

This invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather as being provided for the purpose of illustration and description. In the drawings, the size and relative sizes of structures and regions may be exaggerated for clarity.

As shown in fig. 1-3, the present invention provides a pipette tip insertion device, which comprises a horizontal plate 1, a support plate 2, a rotating plate 3, a barrier strip 4, a separation block 5, a sliding plate 6, a tip box 7, a tip slot 8, an adjusting button 9, and a baffle plate 10. A pair of supporting plates 2 are vertically arranged at both sides of the transverse plate 1, a plurality of groups of through grooves are arranged on the transverse plate 1 in a run-through way, the plurality of groups of through grooves are vertical to the pair of supporting plates 2, a pair of rotating plates 3 are symmetrically hinged at the tops of the through grooves, the movable ends of the rotating plates 3 are positioned in the through grooves, because of the limitation of the rotating plate 3, the gun head can not slide out from the bottom of the through groove, a plurality of groups of barrier strips 4 are arranged above the transverse plate 1 and are parallel to the through groove, the barrier strips 4 are positioned at one side of the opening at the upper end of the through groove, one side of the barrier strips 4 close to the through groove is provided with a sliding groove, a plurality of groups of separating blocks 5 are arranged in the sliding groove in a matching way, a sliding motor is arranged in the separating blocks 5, when a plurality of gun heads are placed in the through grooves, the gravity action of the gun heads is utilized to enable the gun tips to be arranged downwards, the gun heads are shifted to be tightly arranged in the through grooves, then a sliding motor switch is turned on, the separating blocks 5 slide out and are inserted between the gun heads, and a certain gap is formed between the gun heads;
