Abstract
The utility model provides a novel prevent fungus cake hole puncher of blocking up, including ejector pin (1), spring (2), push rod (3), handle (4), a section of thick bamboo (5) that punches. The diameter of the punching cylinder is set to 0.75 cm; the push rod cavity is located a punching section of thick bamboo, and the diameter slightly is less than a punching section of thick bamboo diameter, hugs closely a punching section of thick bamboo inner wall, and the ejector pin is connected on the top, and middle winding spring coupling handle and ejector pin press the ejector pin, and the usable push rod of compression spring is complete with the fungus cake release. The utility model discloses prevent stifled hole puncher, easy operation is convenient, has solved the adhesion of fungus cake and has been in the difficult problem that drops of a section of thick bamboo inner wall that punches, has guaranteed the complete of fungus cake, has reduced the waste of experimental materials, has reduced miscellaneous fungus pollution's possibility, has improved experimental efficiency greatly.
Description
Technical Field
The utility model belongs to the technical field of the microbial cultivation, concretely relates to fungus cake hole puncher who prevents blocking up.
Background
In the microbial cultivation experiment, the hole puncher is as a widely used instrument, involves in the relevant experiment of inoculating the fungus on the culture medium, and the common practice in laboratory at present is simply cut with scalpel, tweezers etc. simply, moves with tweezers and gets, leads to miscellaneous fungus pollution easily, influences the experiment progress. The more standard method is to adopt a common T-shaped puncher to punch holes on the surface of the fungus cakes, pick up the fungus cakes by using a fungus inoculation needle, and inoculate the fungus cakes onto a new culture medium with the reverse side facing upwards. But at the in-process that punches, the fungus cake is difficult for droing appearing easily, blocks up the condition in the hole puncher, in case block up, need disinfect the hole puncher on the alcohol burner again after taking out, and this process has increased the chance that miscellaneous fungus pollutes, influences the fungus effect of connecing, greatly reduced experimental efficiency.
Disclosure of Invention
For solving the shortcoming that exists among the prior art, the utility model provides a prevent hole puncher of fungus cake jam, the simple operation improves experimental efficiency.
In order to achieve the purpose, the utility model adopts the following technical proposal: a novel anti-blocking fungus cake puncher comprises an ejector rod (1), a spring (2), a push rod (3), a handle (4) and a punching barrel (5). The push rod is hollow and located in the punching barrel, the top end of the push rod is connected with the ejector rod, the middle of the push rod is wound with the spring to be connected with the handle and the ejector rod, the ejector rod is pressed, and the compressed spring can completely push out the fungus cakes by the push rod.
The utility model discloses prevent that further technical scheme that stifled fungus cake hole puncher took has: according to the size requirement of the commonly used fungus cake in the microorganism inoculation experiment, the diameter of the punching cylinder is set to be 0.75 cm, the diameter of the push rod is slightly smaller than the diameter of the punching cylinder, the push rod is tightly attached to the inner wall of the punching cylinder, the completeness of the fungus cake can be guaranteed when the push rod is pushed, and the loss of the fungus cake is reduced.
The utility model discloses prevent that further technical scheme that stifled fungus cake hole puncher took has: when using the alcohol burner to disinfect before punching, press ejector pin compression spring, the terminal protractile of push rod is punched a section of thick bamboo end and is disinfected in the lump, effectively reduces the possibility that miscellaneous fungus pollutes, has improved the success rate of experiment.
The utility model discloses prevent that further technical scheme that stifled fungus cake hole puncher took has: above-mentioned ejector pin, push rod, handle, a section of thick bamboo that punches all adopt stainless steel, and high temperature resistant can directly use the alcohol burner to disinfect, but reuse, and the suitability is strong.
The utility model has the advantages of it is following: the utility model discloses prevent stifled fungus cake hole puncher improves on the basis of current T type hole puncher, has effectively solved solid medium and has punched the back fungus cake adhesion and be difficult for the problem that drops on the section of thick bamboo inner wall that punches, has reduced the possibility that miscellaneous fungus pollutes, has guaranteed the complete of fungus cake, has avoided the waste of experimental materials, has saved the experimental time, has guaranteed the progress of experiment.
Drawings
Fig. 1 is a schematic structural view of the punching device of the present invention.
Fig. 2 is a schematic structural view of the compression state of the perforating device of the present invention during use.
Detailed Description
The structure of the utility model is schematically shown, and the utility model is further explained.
As shown in figure 1, the utility model comprises a mandril (1), a spring (2), a push rod (3), a handle (4) and a punching cylinder (5). As shown in figure 2, before the utility model is used, the ejector rod (1) is pressed to compress the spring (2) to push out the push rod (3), and the push rod and the punching cylinder (5) are sterilized by using the alcohol lamp together to avoid pollution. When in use, the push rod (3) can be utilized to completely push out the fungus cakes which are easy to adhere to the inner wall of the perforating cylinder, thereby reducing the loss of the fungus cakes.
In the structure, when in use, firstly, the handle (4) is held by the index finger and the middle finger, the push rod (1) is pressed downwards by the thumb, the punching cylinder (5) and the tail end of the push rod (1) are sterilized by an alcohol lamp, then the thumb is lifted, the punching cylinder (5) is used for punching holes on a culture dish, the push rod (1) is pressed downwards by the thumb when being lifted, the handle (4) is lifted upwards by the index finger and the middle finger simultaneously, the punched fungus cakes are completely pushed out, and then the fungus cakes are inoculated to a new culture medium reversely by the fungus inoculating needle.
The above description is only the preferred embodiment of the present invention, but the present invention is not limited to the above embodiments. According to the utility model discloses all deformations of going on are all covered within the scope of protection of the utility model.
Claims (4)
1. The utility model provides a novel prevent fungus cake hole puncher who blocks up which characterized in that: comprises a mandril (1), a spring (2), a push rod (3), a handle (4) and a punching cylinder (5); the push rod is hollow and located in the punching barrel, the top end of the push rod is connected with the ejector rod, the middle of the push rod is wound with the spring to be connected with the handle and the ejector rod, the ejector rod is pressed, and the compressed spring can completely push out the fungus cakes by the push rod.
