[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1:

[0024] Please refer to Figures 1-5 , the present invention provides a technical solution: an inoculation loop with a needle, including an inoculation loop body 1 and an inoculation needle 2, wherein the inoculation loop body 1 and the inoculation needle 2 can be spliced and installed up and down, and a splicing component 3 is arranged between the inoculation loop body 1 and the inoculation needle 2. The inoculation loop body 1 includes a main handle 11, an extension rod 12 is longitudinally arranged at the upper end of the main handle 11, a conical surface 13 is arranged at the upper end of the extension rod 12, and an inoculation loop 14 is arranged at the upper end of the conical surface 13;

[0025] The inoculation needle 2 includes a first sub-handle 21 and a second sub-handle 22, and inoculation needle tips 23 are arranged at the lower ends of the first sub-handle 21 and the second sub-handle 22, and the lower end of the inoculation needle tip 23 is a contact end 231.

[0026] Specifically, the splicable inoculation loop body 1 and inoculation needle 2 can greatly meet the functions of culturing colonies and selecting colonies, which is conducive to operation and convenient for staff to culture colonies and select single colonies for research.

[0027] As Figure 1 shown: a vertically downward concave slot 211 is arranged on the upper end surface of the first sub-handle 21, and a downward extending clamping groove 212 is arranged at the lower end of the slot 211. This design can connect to the splicing component 3, so as to install the inoculation loop body 1 and the inoculation needle 2 together.

[0028] The splicing component 3 includes a hollow insertion rod 31 fixedly installed at the lower end of the main handle 11. A plug 32 is provided at the lower end of the hollow insertion rod 31, and an inwardly recessed U-shaped recess 33 is provided at the lower end of the plug 32. The hollow insertion rod 31 is inserted into the slot 211, and the plug 32 is inserted into the clamping groove 212. This design can stably insert the inoculation loop body 1 at the upper end of the first sub-handle 21.

[0029] The plug 32 is designed in a trapezoid shape, which can make the connection between the inoculation loop body 1 and the first sub-handle 21 more firm.

[0030] The outer diameter of the inoculation loop 14 is 2.2 mm, and the inner diameter of the loop is 0.8 mm.

[0031] The outer diameter of the inoculation needle 23 is designed to be 1.3 mm.

[0032] The specific working principle of this embodiment is as follows: When culturing bacteria, first hold the main handle 11, place the inoculation loop 14 in the solid medium, and use the streak inoculation method to inoculate bacteria for culture. After the expected culture, single colonies can be obtained.

[0033] In addition to inoculating colonies, the staff also needs to select individual colonies that have completed culturing for research. At this time, one hand pinches the outer wall of the main handle 11, and the other hand pinches the outer wall of the first sub-handle 21, and applying force in opposite directions can pull out the inoculation needle 2. When pulling out the inoculation needle 2, the plug 32 will be squeezed and deformed due to the force, and it will return to its original shape only after the inoculation needle 2 is completely pulled out.

[0034] At this time, hold the first sub-handle 21, align the contact end 231 of the inoculation needle 23 with the colony that has been cultivated in the culture dish, pick out an individual colony for research, and transfer it to the corresponding liquid medium for culture.

[0035] Embodiment 2:

[0036] The difference between this embodiment and Embodiment 1 is that as Figures 4-5 shown: An inwardly recessed part groove 221 is provided at the top of the second sub-handle 22. A connecting seat 222 is provided at the inner bottom of the part groove 221. A spherical shell 223 is provided on the upper end surface of the connecting seat 222. A plurality of hollow grooves 224 are evenly provided on the outer wall of the spherical shell 223. The design of the plurality of hollow grooves 224 on the outer wall of the spherical shell 223 enables the whole spherical shell 223 to be opened to connect to the upper sphere 341.

[0037] The splicing component 3 includes a plug shaft 34 fixedly installed at the lower end of the main handle 11. A sphere 341 is provided at the lower end of the plug shaft 34. The sphere 341 can be stuck inside the spherical shell 223. This design can stably plug the inoculation loop body 1 at the upper end of the second sub-handle 22.

[0038] The specific working principle of this embodiment is as follows: When picking a single colony after cultivation, hold the outer wall of the main handle 11 with one hand and hold the outer wall of the second sub-handle 22 with the other hand, and apply force in opposite directions to pull out the inoculation needle 2. When pulling out the inoculation needle 2, as the sphere 341 is pulled out, the spherical shell 223 will be deformed. Until it is completely pulled out, the spherical shell 223 will return to its original shape. At this time, hold the second sub-handle 22, and a single colony can be picked out for research.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
