Description
Technical Field
The utility model relates to an auxiliary assembly is used in bacterial inoculation, specifically indicates a bacterial inoculator.
Background
When the strains are inoculated to the liquid culture medium, hyphae in the test tube are taken out by adopting a corresponding inoculation transfer device and then are inoculated to the corresponding liquid culture medium. The existing inoculation transfer device generally adopts a metal rod with a draw hook, the metal rod is stretched into a test tube, strains are hooked out through the draw hook, and the strains are inoculated into a corresponding liquid culture medium in a sterile environment. Due to the fact that the drag hook is fixed in position, hypha is not convenient to hook, and after the hypha is inoculated to the liquid culture medium, the hypha is difficult to separate from the drag hook, inoculation time is prolonged, and production efficiency is reduced. Consequently, design a section and can take out the hypha from the test tube fast, and can after the hypha inoculates the liquid medium, make the hypha break away from the inoculation translator fast is the utility model discloses a research purpose.
SUMMERY OF THE UTILITY MODEL
To the problem that above-mentioned prior art exists, the utility model aims to provide a kind of bacterial inoculator can effectively solve the problem that above-mentioned prior art exists.
The technical scheme of the utility model is that:
a strain inoculator comprises a connecting rod and a telescopic rod, wherein a through hole communicated with the upper end and the lower end of the connecting rod is formed in the center of the connecting rod, the telescopic rod is movably sleeved in the through hole, and a positioning plate is fixedly connected to the top end of the telescopic rod; the top end of the connecting rod is provided with a loose spring through a spring mounting groove, and one end of the spring, which is not connected with the connecting rod, is fixedly connected below the positioning plate; two hollow hemispherical shield plates are arranged at the bottom end of the telescopic rod in parallel up and down, a plurality of lotus-shaped grabbing blades are arranged below the shield plates, and the top ends of the grabbing blades are arranged between the two shield plates; the middle position of the grabbing blade is provided with an arc-shaped through hole which is communicated with two side edges of the grabbing blade; the bottom end of the connecting rod is provided with a polygonal frame, and the polygonal frame is connected with the outer side wall of the connecting rod through an L-shaped rod fixedly connected to an end corner of the polygonal frame; the polygonal frame is formed by connecting end to end round rollers which have the same number with the grabbing blades and penetrate through arc-shaped through holes of the grabbing blades.
And the connecting rod is provided with an annular limiting plate at the outer side of the spring mounting groove.
The grabbing blade is at least three pieces.
The utility model has the advantages that:
the utility model discloses a on the reset mechanism's that traditional connecting rod, telescopic link and spring constitute basis, set up two hemispherical guard shield plates of cavity at the telescopic link low side, and be provided with between the guard shield plate and communicate the blade that snatchs in the guard shield plate outside, snatch the blade and can carry out sliding connection through the multilateral frame that sets up through connection, multilateral frame rigid coupling is in the connecting rod outside. Therefore, when the spring is compressed, the grabbing leaves form an open lotus shape to cover above the hyphae, and when the spring is reset, the grabbing leaves form a closed lotus shape to grab the hyphae. Through the closure of snatching the blade with open and be used for the extraction and the inoculation of hypha, through the state of opening that contracts of its result and spring, the compression spring makes when using before will extracting and inoculating and snatch the blade and open, and the removal in-process between extraction and inoculation uses the spring that resets to avoid traditional aversion to need artifical incessant compression spring to get the inoculator of material, the utility model discloses the manual control time is short, and the mistake that it leads to also can corresponding reduction, and the hypha snatchs the possibility and the quantity that drops in-process and can reduce.

Detailed Description
To facilitate understanding of those skilled in the art, the structure of the present invention will now be described in further detail with reference to the following examples:
referring to fig. 1-4, a strain inoculator comprises a connecting rod 1 and a telescopic rod 2, wherein a through hole communicated with the upper end and the lower end of the connecting rod 1 is formed in the center of the connecting rod 1, the telescopic rod 2 is movably sleeved in the through hole, and a positioning plate 5 is fixedly connected to the top end of the telescopic rod 2; the top end of the connecting rod 1 is provided with a loose spring 4 through a spring mounting groove 3, and one end of the spring 4, which is not connected with the connecting rod 1, is fixedly connected below the positioning plate 5; two hollow hemispherical shield plates 6 are arranged at the bottom end of the telescopic rod 2 in parallel up and down, and the outer diameter of each shield plate 6 is smaller than that of each through hole; a plurality of lotus-shaped grabbing blades 7 are arranged below the shield plates 6, and the top ends of the grabbing blades 7 are arranged between the two shield plates 6; the middle position of the grabbing blade 7 is provided with an arc-shaped through hole 71 communicated with two side edges of the grabbing blade 7; the grabbing blades 7 form a closed lotus shape and form an accommodating cavity capable of loading hyphae; the bottom end of the connecting rod 1 is provided with a polygonal frame 8, and the polygonal frame 8 is connected with the outer side wall of the connecting rod 1 through an L-shaped rod 9 fixedly connected to an end corner of the polygonal frame 8; the polygonal frame 8 is formed by connecting end to end circular rollers 81 which are the same as the grabbing blades 7 in number and penetrate through the arc-shaped through holes 71 of the grabbing blades 7; the round roller is of an arc-shaped structure and is matched with the grabbing blade; the middle of the grabbing blade 7 penetrates through the round roller 81 through the arc-shaped through hole 71 and is slidably mounted on the polygonal frame 8.
