Description

Technical Field

[0001] The utility model relates to a tweezer knife, in particular to a tweezer knife special for tissue culture. Background Art

[0002] Plant tissue culture is a new asexual reproduction technology developed in recent decades. Based on the totipotency of plant cells, this technology places explants in vessels such as tissue culture bottles, and performs tissue culture under sterile conditions to obtain tissue culture seedlings. Scientific research units can quickly obtain plant materials that have been growing steadily, and production can be highly intensive and easy to automate. It is the development direction of future agricultural factory seedling cultivation. In the material transfer process of conventional tissue culture, when the material volume is large or the bottle seedling is high, the material should be taken out with tweezers first, and then cut or shortened with a scalpel, or cut or shortened with scissors, and then transferred to fresh culture medium with tweezers.

[0027] The specific usage scenario of this embodiment is: by setting the scissor blade 200 to cut the tissue culture structure clamped by the forceps head 1 300 and the forceps head 2 330, by setting the scissor mouth 333 to facilitate the rotation of the scissor blade 200 from the inside of the scissor mouth 333 when the scissor blade 200 is pressed, so as to cut the tissue culture structure and avoid motion interference between the scissor blade 200 and the inner wall of the forceps head 2 330, by setting the latch piece 2 332 and the latch piece 1 310 to be used in conjunction with the forceps head 1 300, the forceps head 2 330 and the forceps frame 100, the stability of the installation of the forceps head 1 300 and the forceps head 2 330 is improved.

[0028] Example 3: Figure 1 and Figure 2 , including a tweezers frame 100, an opening 130 is opened on the inner wall of one side of the tweezers frame 100, and a scissor blade 200 can be detachably plugged into the inner wall of the opening 130, a slot 120 is opened on the end of the tweezers frame 100 close to the scissor blade 200, and a tweezers head 330 is plugged into the inner wall of the slot 120, and a tweezers head 300 is opened on the end of the tweezers frame 100 away from the scissor blade 200, and the tweezers head 330 and the connection between the tweezers head 300 and the inner wall of the tweezers frame 100 are detachably fixedly connected by bolts, and the latch piece 332 is plugged into the inner wall of the slot 120, and a clamp plate 331 is fixedly installed on the front outer wall of the tweezers head 330, and a clamp plate 320 is fixedly installed on the front outer wall of the tweezers head 300, and the clamp plate 320 and the clamp plate 331 cooperate to clamp the tissue culture structure.

[0029] The specific usage scenario of this embodiment is: by setting the splint 1 331 and the splint 2 320 for use together, it is convenient to press the outer walls on both sides of the tweezers frame 100, so that the splint 1 331 and the splint 2 320 can clamp the tissue culture structure, thereby improving the stability of the clamped tissue culture structure.

[0030] The working principle of the utility model is as follows: when using the utility model, a technician in this field plugs and connects the tweezer head 1 300 and the tweezer head 2 330 with the slot 1 120 and the slot 2 110 inside the tweezer frame 100 respectively, and then fixes and connects the tweezer head 1 300 and the tweezer head 2 330 with the tweezer frame 100 at the connection point by a bolt 340, thereby improving the stability of installing the tweezer head 1 300 and the tweezer head 2 330, and then plugs and connects the scissor blade 200 with the inner wall of the opening 130. When using the tweezer knife, by holding the tweezer frame 100, the tweezer head 1 300 and the tweezer head 2 330 are aligned. The quasi-tissue culture structure is achieved by pressing the outer walls on both sides of the forceps frame 100 so that the forceps head 1 300 and the forceps head 2 330 move toward each other synchronously, thereby clamping and fixing the tissue culture structure through the two forceps heads 1 300 and the forceps head 2 330. When the tissue culture structure needs to be cut, the push rod 220 on the outer wall of the scissor blade 200 is pressed so that the scissor blade 200 cuts the tissue culture structure between the forceps head 1 300 and the forceps head 2 330. When the scissor blade 200, the forceps head 1 300 and the forceps head 2 330 are damaged, the single damaged component can be replaced by removing the single damaged component.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
