Description

Tobacco leaf puncture device special for tobacco inoculation test Technical Field The invention relates to the technical field of tobacco inoculation, in particular to a tobacco puncturing device special for a tobacco inoculation test. Background In the scientific research of tobacco breeding, the resistance of the breeding material to virus diseases is known by means of artificial inoculation of diseases. The conventional inoculation method is to use a little silicon carbide (600 meshes) or diatomite to repeatedly and gently rub on the inoculated leaves continuously, and only the epidermal cells of the leaves are required to cause micro-wounds without death, and then the leaves are smeared with virus juice so as to achieve the purpose of infection inoculation. This conventional inoculation method requires high skill of operators, and in addition, in order to ensure success rate of inoculation, the operators need to repeatedly and gently rub, which tends to increase labor intensity of operators and cause low inoculation efficiency. For example, chinese patent CN 207219489U discloses a tobacco leaf puncturing device special for tobacco inoculation test, which comprises a forceps head and a baffle plate arranged below the forceps head, wherein the forceps head is connected with the baffle plate through a bending handle, and a plurality of needles are uniformly distributed at the bottom of the forceps head. The special tobacco leaf puncturing device for the tobacco inoculation experiment of the structure improves the tobacco virus inoculation efficiency and reduces the labor intensity of test operators. The above-mentioned pjncture needle is fixed state, can't protect the tip of pjncture needle when not using, and like this a convenience can lead to the risk that causes the fish tail of relevant personnel easily when not using, influences safe application, and simultaneously, the needle body under the fixed state can't dismantle again, leads to its clearance change comparatively inconvenient, and exposes in outside needle body can cause the fish tail to other regions of tobacco leaf very easily again when puncturing the operation all the time, and influences its own stable growth, for this reason proposes a tobacco leaf special-purpose puncture device of tobacco inoculation test. Disclosure of Invention Based on the above, it is necessary to provide a tobacco puncturing device special for tobacco inoculation test, in which a needling protector (including a fixed cylinder and a protective cylinder) cooperates with a spring, so that the needling needle can be completely retracted into the protective cylinder in a non-use state, thereby avoiding accidental injury to operators or accidental damage to other articles.
