Embodiment 1

[0039] Such as Figure 1-8 As shown, the present embodiment provides a folding medium cutting knife, including 8 cross-cutting knives and 6 vertical cutting knives, and the cross-cutting knives include 4 first cross-cutting knives 101 and 4 second Cross-cutting knife 102, the length of the first cross-cutting knife 101 is less than the length of the second cross-cutting knife 102, and the length of the first cross-cutting knife 102 includes 2 first longitudinal cutting knives 111 and 4 second longitudinal cutting knives 112. The length of the first slitter 111 is smaller than the length of the second slitter 112 .

[0040] The length of the first cross-cutting knife 101 and the second cross-cutting knife 102 is n*15mm, wherein 1≦n≦5, in this embodiment, the first cross-cutting knife 101 is set to 45mm, and the second cross-cutting knife 102 is set to 75mm . The length of the first slitting knife 111 and the second slitting knife 112 is N*15mm, where 1≦N≦7. In this embodiment...

Embodiment 2

[0054] Such as Figure 9 , 10 As shown, this embodiment further optimizes the design on the basis of Embodiment 1, specifically: add a casing 133, firstly put the core 131 in the casing 133, and then put the casing 133 in the casing 132, This makes the connection more stable and prevents the core 131 from slipping out of the opening of the housing 132 during use.

[0055] The sleeve body 133 has a hollow cylinder structure, the hollow structure just accommodates the core body 131, and holes are also provided on the side wall of the cylinder body. The closed end is parallel to the surface of the housing 132, which prevents the core 131 from slipping out of the housing 132 during rotation.

Embodiment 3

[0057] Such as Figure 11 As shown, the present embodiment provides a foldable medium cutting knife, including 4 cross-cutting knives and 6 longitudinal cutting knives, and the cross-cutting knife is installed on the longitudinal cutting knife through the rotation of the core body 1301 and the housing 1302. on the knife. The cross-cutting knife comprises 2 first cross-cutting knives 101 and 2 second cross-cutting knives 102, the length of the first cross-cutting knife 101 is less than the length of the second cross-cutting knife 102, and the longitudinal cutting knife comprises 2 first longitudinal cutting knives 111 With four second slitting knives 112 , the length of the first slitting knife 111 is smaller than the length of the second slitting knife 112 .

[0058] Wherein, the length of the first cross-cutting knife 101 is 30 mm, the length of the second cross-cutting knife 102 is 50 mm; the length of the first slitting knife 111 is 15 mm, and the length of the second slit...

Abstract

The invention relates to a foldable culture medium cutter which comprises two or more groups of parallelly arranged transverse cutting knives. Two or more groups of parallelly arranged longitudinal cutting knives are vertically arranged on the transverse cutting knives, a shell is arranged on the transverse cutting knives, a core body is arranged on the longitudinal cutting knives, the longitudinal cutting knives are installed on the transverse cutting knives in a rotating fit mode through the core body and the shell, and independent cutting units are formed after the transverse cutting knivesand the longitudinal cutting knives are installed and connected. A detachable handle is mounted on each transverse cutting knife or each longitudinal cutting knife, the handle comprises two cross-connected arm supports, telescopic supports are mounted at two ends of each transverse cutting knife or each longitudinal cutting knife, sliding blocks are movably mounted at the bottoms of the supports,and the surfaces of the sliding blocks are smooth curved surfaces. The culture medium cutter is simple in structure, convenient to operate, small in size and convenient to carry, damage to the culture medium structure can be reduced when a culture medium is adopted, culture medium pollution cannot be caused, and the culture medium separation time is short and the accuracy is high.

Description

technical field [0001] The invention belongs to the technical field of culture medium separation, and in particular relates to a foldable culture medium cutter. Background technique [0002] The culture medium in the solid culture medium is distributed on the surface of the petri dish. When it is necessary to take the culture medium at different positions for analysis, in the prior art, a sterile blade is usually used to separate the culture medium. In the process, the structure of the medium will be destroyed, and it will also cause contamination of the medium; when multiple mediums in different positions are required, a sterile knife is used to separate the medium, which takes a long time and cannot keep a straight line during the cutting process , medium separation is not accurate. [0003] At present, there is a cutting knife, including a cutting knife body. The cutting knife body is composed of a plurality of parallel horizontal knife units. There is a blade under the ...
