Description

A kind of fungi transfer needle

Technical field

The utility model relates to a kind of fungi transfer needles, belong to strain inoculating tool technical field.

Background technique

Currently, existing fungi transfer needle is a metallic rod, a wire is filled at its end, for straight or curves hook Shape.When inoculation the mycelia seldom for single mycelia or quantity can very easily direct picking, but in the training for being put into inoculation Mycelia is easy to be stained on the end of transfer needle when supporting on base, it has not been convenient to do from transfer needle, and mycelia cannot be very accurate Ground is seeded on culture medium designated position, is made troubles to inoculation work.

Utility model content

In view of the deficiencies of the prior art, the utility model provides the fungi transfer needle of new structure, utilizes the inoculation Needle can easily do mycelia from transfer needle end, and can accurately be seeded in the position specified on culture medium.

The technical solution of the utility model is as follows:

A kind of fungi transfer needle, including main body, are provided with push top and handle in main body, and handle and push top connect, pass through Handle pushes push top by the mycelium inoculation of body ends on culture medium.

Preferably, by sleeve connection between the handle and push top, push top, sleeve, handle sleeve are in main body.

Preferably, felt layers are provided on the inner wall of the sleeve and body contact.The benefit of this design is to increase sleeve Frictional force between main body, prevents sleeve from surprisingly sliding in main body.

Preferably, it is connected between the handle and push top by stock, offers slideway in main body, stock is placed in slideway It is interior.The benefit of this design is that user pushes handle, by sliding of the stock in slideway, to make push top move, while can Prevent the rotation having a haircut in main body radially.

Preferably, the push top is a disk, and center opening, the inner ring in hole is connected with cross open silica gel piece.This design Benefit be, when push top is sleeved in main body, cross open silica gel piece lock ring in main body, increase push top main body between Frictional force prevents have a haircut unexpected sliding and rotation.

The utility model has the beneficial effects that:

1) the utility model transfer needle is pointedly improved on the basis of conventional vaccination needle, has both been saved existing The shortcomings that having the advantages of transfer needle, and overcoming existing transfer needle simultaneously.

2) mycelia can be pushed down by push top from the end of transfer needle on the utility model transfer needle, while can be disposable Ground is seeded in the position specified on culture medium, and high-efficient, accuracy rate is also high.

3) there is the utility model transfer needle smart structural design, easy to operate, easy to use good user to use body It tests, is worthy of popularization.

Detailed description of the invention

Fig. 2 is the structural schematic diagram (slideway structure) of 2 transfer needle of embodiment；

Fig. 3 is the top view of Fig. 2；

Fig. 4 is the structural schematic diagram having a haircut in the utility model；

Wherein: 1, main body；2, it has a haircut；3, sleeve；4, handle；5 slideways；6, silica gel piece.

Specific embodiment

The utility model is described further by way of example and in conjunction with the accompanying drawings, but not limited to this.

Embodiment 1:

As shown in Figure 1 and Figure 4, it the present embodiment provides a kind of fungi transfer needle, including main body 1, is provided with and pushes away in main body First 2 and handle 4, handle 4 connect with push top 2, pushed by handle 4 have a haircut 2 by the mycelium inoculation of 1 end of main body in culture medium On.

Specifically, main body is a long cone, end is tip, is used to the single mycelia of picking or a part of mycelia, handle 4 It is connect between push top 2 by sleeve 3, push top 2, sleeve 3, handle 4 are sleeved in main body.Push top 2, sleeve 3, handle 4 are one Forming structure manufactures, and offers on push top 2 and handle 4 for the perforative through-hole of main body 1.

Felt layers are provided on the inner wall that sleeve 3 is contacted with main body 1.Felt layers can increase between sleeve 3 and main body 1 Frictional force prevents the unexpected sliding on the body 1 of sleeve 3.

2 are had a haircut as a disk, center opening, the inner ring in hole is connected with cross open silica gel piece 6.When push top is sleeved on main body When upper, cross open silica gel piece lock ring increases the frictional force between push top and main body in main body, prevent from having a haircut unexpected sliding and Rotation.

In the present embodiment, in addition to silica gel piece, other structures are all made of 304 stainless steel materials and are made.

In use, tip, is then aligned on culture medium by the tip picking hypha,hyphae of experimenter's transfer needle main body The position to be inoculated with, pushes forward handle, and the mycelia on tip is pushed the position to be inoculated on culture medium by the push top of front. Whole process is easy to operate, efficiently and accurately, and once-through operation can be inoculated with success.

Embodiment 2:

As shown in Figure 2, Figure 3 and Figure 4, a kind of fungi transfer needle, structure is as described in Example 1, the difference is that: It is connected between hand 4 and push top 2 by stock, offers slideway 5 in main body 1, stock is placed in slideway 5.User pushes handle 4, by sliding of the stock in slideway 5, so that push top 2 moves forward, while turn of push top 2 radially in main body 1 can be prevented It is dynamic.

Claims (1)

1. a kind of fungi transfer needle, including main body, which is characterized in that be provided with push top and handle, handle and push top in main body Connection pushes push top by the mycelium inoculation of body ends on culture medium by handle；Pass through set between the handle and push top Cylinder connection, push top, sleeve, handle sleeve are in main body；Felt layers are provided on the inner wall of the sleeve and body contact；It is described It is connected between handle and push top by stock, offers slideway in main body, stock is placed in slideway；The push top is a disk, Center opening, the inner ring in hole are connected with cross open silica gel piece.
