A special tweezers of stamen adjustability are got rid of to rice, includes the body, and the body includes first tweezers handle and second tweezers handle, and a tip of first tweezers handle and a tip of second tweezers handle are connected, are equipped with the through -hole on first tweezers handle, are equipped with the bar hole on second tweezers handle, and the pole portion of screw wears to establish on through -hole and bar hole to threaded connection has the nut in the pole portion of screw, and first tweezers handle and second tweezers level holder are between the cap portion and nut of screw.
Description
Technical field
This utility model belongs to the technical field of tweezers, concretely relates to a kind of Oryza sativa L. and removes stamen adjustability Special-purpose forceps.
Background technology
At present, tweezers are used to artificial removal's Oryza sativa L. stamen organ in rice breeding process, carry out artificial hybridization and realize the simplest and modal instrument of different germ plasm resource gene exchange.Technical operation personnel with shears rice glume cut one domatic after, with in tweezers deeply grain husk shell, each piece of flower pesticide (male organs) is pressed from both sides out thus reaching the purpose of artificial removal's stamen, pollination (hybridization) for realizing allos pollen is ready, and this is also the current Oryza sativa L. the most safe and effective method of artificial hybridization.But use tweezers to carry out that the process of artificial removal's stamen exists techniques below problem: (1) different rice glume openings of sizes is different, remove the flower pesticide in each piece of clever shell to be required for readjusting tweezers caliber size and could safety be deep in grain husk shell, tweezers effectively use frequency and efficiency all very low；(2) by the flower pesticide process of pressing from both sides out, operator is careless slightly, and tweezer mouth magnifies, and grain husk shell cannot be used to hybridization by damaged.Obviously, efficiency is low and fragile grain husk problem, this efficiency directly affecting artificial hybridization and the success or failure such as shell to use the process that stamen removed by tweezers to exist.
Summary of the invention
The purpose of this utility model is to provide a kind of Oryza sativa L. and removes stamen adjustability Special-purpose forceps, and it can improve working performance, and it can be avoided that grain husk shell damages in operation process.
For solving above-mentioned technical problem, the purpose of this utility model is achieved in that
A kind of Oryza sativa L. removes stamen adjustability Special-purpose forceps, including body, body includes the first tweezer handle and the second tweezer handle, the one end of the first tweezer handle and the one end of the second tweezer handle are connected, being provided with through hole in the first tweezer handle, be provided with bar hole in the second tweezer handle, the bar portion of screw is located on through hole and bar hole, and threaded in the bar portion of screw have nut, and the first tweezer handle and the second tweezer handle are clipped between cap portion and the nut of screw.
On the basis of such scheme and as the preferred version of such scheme: be provided with block in the bar portion of screw, this block offsets for nut, and block is threadeded with the bar portion of oncomelania, and block is positioned at the outside of nut.
This utility model highlights and useful having the technical effect that compared to existing technology
Oryza sativa L. of the present utility model removes stamen adjustability Special-purpose forceps, owing to the first tweezer handle and the second tweezer handle are clipped between cap portion and nut, furthermore nut is threadeded with screw, the tweezer mouth size so making body is adjustable, before using, tweezer mouth is adjusted to suitable size, grain husk shell can be effectively prevented from when operation and damage.Furthermore, tweezer mouth is relatively small, and the speed of such tweezer is compared comparatively fast, improves the efficiency of artificial hybridization.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is partial structurtes enlarged drawing of the present utility model.
Detailed description of the invention
This utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1 Fig. 2；
This gives a kind of Oryza sativa L. and remove stamen adjustability Special-purpose forceps, including body 1, screw 2 and nut 3.Wherein, body 1 includes the first tweezer handle 4 and the second tweezer handle 5, the one end of the first tweezer handle 4 and the one end of the second tweezer handle 5 and is connected, and is provided with through hole in the first tweezer handle, and the internal diameter of through hole is slightly less than the cap portion of screw.Being provided with bar hole 8 in the second tweezer handle, the width of bar hole 8 is slightly less than the external diameter of nut.The bar portion of screw is located on through hole and bar hole, and threaded in the bar portion of screw has nut 3, and the first tweezer handle and the second tweezer handle are clipped between cap portion and the nut of screw.Generally, the aperture of tweezer mouth 6 is 3mm ~ 8mm.Owing to the first tweezer handle and the second tweezer handle are clipped between cap portion and nut, furthermore nut is threadeded with screw, and the tweezer mouth size so making body is adjustable, before using, tweezer mouth is adjusted to suitable size, can be effectively prevented from grain husk shell when operation and damage.Furthermore, tweezer mouth is relatively small, and the speed of such tweezer is compared comparatively fast, improves the efficiency of artificial hybridization.
As shown in FIG., being provided with block 7 in the bar portion of screw 2, block 7 is threadeded with the bar portion of oncomelania, and this block offsets for nut 3, and block 7 is positioned at the outside of nut 3.Adopt this structure, it is possible to be effectively prevented nut pine and move back, in use ensure tweezer mouth open after size do not change.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
