Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
The present 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 providing a thorough and complete disclosure. In the drawings, the size and relative sizes of structures and regions may be exaggerated for clarity.
As shown in fig. 1-3, the utility model provides a cotton swab breaking device for nucleic acid sample collection, including placing case 1, case lid 2, recess 3, sample groove 4, cutter groove 5, splint groove 6, cutter 7, splint 8 and inductive switch 9. A box cover 2 is hinged to one side of the top of the placing box 1; the plurality of grooves 3 are arranged at the top of the placing box 1 in parallel and are perpendicular to the hinged part of the box cover 2 and the placing box 1, one side of each groove 3, far away from the box cover 2, is communicated, so that a nucleic acid kit can be conveniently placed, a plurality of sample grooves 4 are formed in the bottoms of the grooves 3 in a matched mode, and the nucleic acid kit is placed into the sample grooves when the kit placing box is used;
a pair of knife grooves 5 and a pair of clamping plate grooves 6 are symmetrically formed in the opposite side walls of the groove 3, the knife grooves 5 are located right above the clamping plate grooves 6, a pair of cutters 7 are arranged in the cutter grooves 5 in a matched and sliding mode, the two cutters can slide relatively and penetrate through the knife grooves 5 to be abutted with each other to cut off cotton swabs, the cutters 7 are connected with a first driving device, the opposite sides of the cutters 7 can be abutted with each other, a pair of clamping plates 8 are arranged in the clamping plate grooves 6 in a matched and sliding mode, the pair of clamping plates 8 can slide relatively and penetrate through the clamping plate grooves 6 to extrude the cotton swabs, and rubber cushions are arranged on the opposite sides of the pair of clamping plates 8 in the embodiment; splint 8 is connected with second drive arrangement, is provided with inductive switch 9 near the recess 3 opening, is provided with infrared inductor in the inductive switch 9, and inductive switch 9 is connected with first drive arrangement and second drive arrangement, and a pair of cutter 7 is unanimous with the direction of motion of a pair of splint 8, and in this embodiment, the velocity of motion in opposite directions of a pair of splint 8 is greater than the velocity of motion in opposite directions of a pair of cutter 7, and the velocity of motion in opposite directions of a pair of splint 8 is less than the velocity of motion in opposite directions of a pair of cutter 7.
