[0021] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0022] Please refer to Figures 1-4 The utility model provides a novel disposable inoculation device technical scheme: including inoculation needle 1, inoculation ring 2, roller 4, handle 3, switching structure, the inoculation needle 1 with inoculation ring 2 all are fixed on roller 4, roller 4 rotates and is installed in handle 3, switching structure acts on roller 4, makes roller 4 rotate,

[0023] The switching structure comprises a sliding rail 62 arranged on the handle 3, a sliding block 63 mounted on the sliding rail 62, a push block 64 connected with the sliding block 63, and a connecting rod 61 hingedly mounted on the push block 64; the sliding block 63 slides along the sliding rail 62, so that the push block 64 drives the connecting rod 61 to move; the other end of the connecting rod 61 is hingedly connected with the roller 4.

[0024] Working principle: by pushing the sliding block 63, the push block 64 moves, and then the connecting rod 61 moves, and the rotation of the roller 4 is driven by the pulling of the connecting rod 61, since the inoculation needle 1 and the inoculation ring 2 are fixed on the roller 4, so that the rotation of the roller 4 changes the positions of the inoculation needle 1 and the inoculation ring 2, thereby achieving the purpose of switching the inoculation needle 1 and the inoculation ring 2.

[0025] Further, the handle 3 is hollow inside for placing the switching structure.

[0026] The front end of the handle 3 is in a sheet shape, and an axle seat 5 is arranged at the front end of the handle, the roller 4 is sleeved on the axle seat 5, so that the roller 4 is rotationally connected with the handle 3. The front end of the handle 3 is designed in a sheet shape, which is convenient for the installation of the roller 4, and the roller 4 can be directly sleeved on the axle seat 5, and the inoculation needle 1, the inoculation ring 2 and the roller 4 can be used as disposable products, which can be quickly taken out after use, so that the new roller 4 and the inoculation needle 1 and the inoculation ring 2 can be replaced, so that there is no need to replace the new handle 3.

[0027] Further, the handle 3 is hollow inside for placing the switching structure.

[0028] The roller 4 is in a hollow cylindrical shape, the axle seat 5 is in a cylindrical shape, the length of the axle seat 5 is shorter than the length of the roller 4, and the protrusion 41 is located on the front surface of the roller 4. In this way, the installed connecting rod 61 will not be affected by the axle seat 5 when it moves.

[0029] The inoculation needle 1 and the inoculation ring 2 are fixed on the side surface of the roller 4, and when the roller 4 rotates, the inoculation needle 1 and the inoculation ring 2 on the side surface will rotate, and in one embodiment, the inoculation needle 1 and the inoculation ring 2 are placed at 90°, and the arc length of the protrusion 41 rotating 90° with the roller 4 is equal to the length of the push block 64 that can be displaced, so that when the sliding block 63 slides to the leftmost position, it corresponds to the inoculation needle 1, and when it slides to the rightmost position, it corresponds to the inoculation ring 2. Further, the surface of the sliding block 63 has a pattern for preventing the fingers from slipping.

[0030] Further, the connecting rod 61 is made of stainless steel, so that the connecting rod 61 has certain strength to facilitate force conduction, and has certain toughness to facilitate disassembly and assembly with the protrusion 41.

[0031] Further, in order to avoid splashing of the inoculation needle and aerosol pollution, the inoculation needle 1 has a pre-notched gap 11 at the end, so that the inoculation needle 1 is separated from the roller 4; after use of the inoculation needle 1 is finished, the inoculation needle can be broken along the pre-notched gap 11 and discarded.

[0032] Working principle: by pushing the slider 63 to slide on the slide rail 62, the push block 64 connected with the slider 63 moves, and in turn drives the connecting rod 61 hinged on the push block 64 to move; the other end of the connecting rod 61 is hinged with the roller 4, so that the movement of the connecting rod 61 will pull the roller 4 to rotate; since the inoculation needle 1 and the inoculation ring 2 are both fixed on the roller 4, the rotation of the roller 4 will change the orientation of the inoculation needle 1 and the inoculation ring 2, so as to realize the switching of the inoculation needle 1 and the inoculation ring 2.

[0033] The above shows and describes the basic principles and main features of the present application and the advantages of the present application, and it is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or essential characteristics of the present application.
