[0002] At present, the inoculation needles in the prior art can only be used in laboratories and cannot be used for inoculation operations in field environments. Moreover, when piercing the peel for inoculation, multiple inoculation needles cannot adapt to the curvature of the fruit surface, which easily leads to inconsistent penetration depths of multiple inoculation needles into the peel.

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] like Figure 1-5 As shown, a simple field fungus quantitative inoculation needle comprises a connector 1, the upper end of which is connected to the working end of a liquid quantitative control flow meter, the lower end opening of which is communicated with the upper end of a connecting tube 2, the outer peripheral surface of which is slidably connected to a sleeve 4, the lower end of which is communicated with a puncture body 5, and a fastening nut 3 is movably installed on the upper end of the sleeve 4;

[0024] By connecting with the liquid quantitative control flowmeter, quantitative control of the fungal culture solution is achieved, so that the flow rate of the inoculation needle is 1-10 microliters;

[0025] The sleeve can drive the puncture body to move up and down along the outer peripheral surface of the connecting tube to meet the needs of multiple inoculation needles to inoculate fruits at the same time, and can ensure that the depth of each puncture body piercing into the fruit peel remains consistent.

[0026] Specifically, the upper end of the sleeve 4 is configured to be conical, and an external thread is provided on the outer peripheral surface of the upper end of the sleeve 4. When the sleeve moves a certain distance along the connecting pipe, the sleeve is fixedly connected to the connecting pipe by tightening the nut and the upper end thread connection of the sleeve. Furthermore, a sealing sleeve is also provided at the joint between the upper end of the sleeve and the connecting pipe to ensure the sealing performance between the sleeve and the connecting pipe.

[0027] Specifically, a connecting plate 9 is installed on the outer peripheral surface of the lower end of the sleeve 4, and the connecting plate 9 is threadedly connected to the limiting rod 10, so that the lower end of the limiting rod and the needle tip of the piercing body are kept on the same horizontal plane. When the depth of piercing into the peel needs to be adjusted, the limiting rod is adjusted upward. At this time, the height difference between the lower end of the limiting rod and the needle tip of the piercing body is the depth of the piercing body piercing into the fruit;

[0028] Furthermore, scale lines are engraved on the outer circumferential surface of the limit rod, and the zero scale line of the limit rod is located at the lower end of the limit rod.

[0029] Specifically, it also includes a protection component, which is sleeved on the outer peripheral surface of the puncture body 5. The protection component can effectively block the needle of the puncture body to prevent the puncture site of the puncture body from being exposed to the outside air for a long time.

[0030] Specifically, the protection component includes an elastic cavity 6, the elastic cavity 6 abuts against the upper end of the telescopic tube 7, a rubber head 8 is installed at the lower end of the telescopic tube 7, the elastic cavity is fixedly connected to the outer peripheral surface of the puncture body, the telescopic tube can be telescoped relative to the elastic cavity, and the opening diameter of the rubber head is slightly smaller than the outer diameter of the puncture body. When the rubber head is located at the needle position of the puncture body, a blocking operation can be achieved to prevent the external air containing bacteria from contacting the inside of the puncture body;

[0031] Furthermore, a sterilization device is placed in the telescopic tube to sterilize the bacteria on the outer surface of the puncture body;

[0032] The lower surface of the rubber head 8 is flush with the needle tip of the puncture body 5, and the inner ring wall of the rubber head 8 abuts against the outer wall of the puncture body 5, so that the juice and debris after the puncture of the puncture body are blocked on the lower surface of the rubber head;

[0033] During the puncture operation, the lower surface of the rubber head contacts the peel of the fruit. When the inoculation needle is pressed downward, the puncture body is pushed out from the lower surface of the rubber head and pierces into the peel to realize the puncture inoculation operation.

[0034] The method of using the present invention, such as Figure 2-3 As shown:

[0035] When an inoculation needle is installed at the lower end of the liquid quantitative control flowmeter, the depth of penetration into the peel is controlled by adjusting the height difference between the lower end of the limit rod and the needle head of the puncture body. After adjusting the height, the preset working parameters of the liquid quantitative control flowmeter are installed to penetrate into the peel.

[0036] When multiple inoculation needles are installed at the lower end of the liquid quantitative control flowmeter:

[0037] First, loosen the fastening nut to allow the sleeve to droop naturally, and make the lower end of the limit rod abut against the peel. At this time, the rubber heads of multiple inoculation needles will also abut against the peel.

[0038] Then, tighten the fastening nuts respectively so that the sleeves of the multiple inoculation needles are fixedly connected to the connecting tubes;

[0039] Secondly, adjust the limit rod upwards so that the lower end of the limit rod is separated from the peel. The difference in distance between the lower end of the limit rod and the peel is the depth of the piercing body piercing the peel.

[0040] Finally, press down the puncture body, the puncture body extends from the rubber head and pierces into the fruit, completing the inoculation operation according to the preset parameters of the liquid quantitative control flowmeter.

[0041] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variation thereof are intended to cover non-exclusive inclusion, so that a process, method, article or seal including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or seal.

[0042] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
