They are only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this patent.

[0024] In the description of this patent, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," and "set" should be understood in a broad sense. For example, they can refer to fixed connection or set, detachable connection or set, or integral connection or set. Those skilled in the art will understand the specific meanings of the above terms in this patent based on the specific circumstances.

[0025] like Figure 1-2As shown, a preferred embodiment of the present invention shows a Chinese medicine drug sensitivity agar plate puncher, comprising a base column 1, a plurality of brackets 4 and a second screw 6. The base column 1 has a cylindrical hollow portion 11. The cylindrical hollow portion 11 is provided with an internal thread, and the first screw 2 matches the cylindrical hollow portion 11, so that the free end of the first screw 2 can be rotated through the cylindrical hollow portion 11 to extend to the outside and be fixed by a nut 3. The plurality of brackets 4 are evenly distributed on the periphery of the base column 1. Each bracket 4 has a rectangular hollow portion 41, and the inner periphery of the rectangular hollow portion 41 is covered with a rubber gasket 5. The second screw 6 is arranged at the rectangular hollow portion 41. The second screw 6 matches the rectangular hollow portion 41, so that the free end of the second screw 6 can extend through the rectangular hollow portion 41 to the outside and be fixed by a nut 7. Second screw 6 can translate or slide vertically within rectangular hollow portion 41, generating friction between second screw 6 and rubber washer 5, securing second screw 5 within rectangular hollow portion 41. Bracket 4 is connected to base column 1 at one end and has a support leg 8 at the other end. Bracket 4 can be fixed to the periphery of base column 1 by any method feasible in the art, including but not limited to welding.

[0026] Furthermore, the base column 1 has a circular, quadrilateral, pentagonal, or hexagonal shape. When the base column 1 has a circular shape, the number of brackets 4 can be 4, 5, or 6. When the base column 1 has a quadrilateral shape, the number of brackets 4 is 4; when the base column 1 has a pentagonal shape, the number of brackets 4 is 5; and when the base column 1 has a hexagonal shape, the number of brackets 4 is 6.

[0027] Furthermore, the rectangular hollow portion 41 of the bracket 4 is provided with scale lines ranging from 0 to 5 cm.

[0028] Furthermore, the height of the support foot 8 is 1.5-2.0 cm. The support foot 8 is provided with a thread, and the height of the support foot 8 can be increased by using different types of full-cover nuts.

[0029] Furthermore, both the first and second screws 2, 6, are marked with scale lines. The height of the first and second screws 2, 6 is 2-4 mm lower than the height of the support foot 8. When the nut 3 is tightened on the first screw 2, it is 0.1-0.15 cm away from the bottom surface of the plate. The diameter and depth of the hole can be adjusted by adjusting the nut and screw structure. The second screw 6 is marked with a 50-μl height. For example, a 0.5 cm diameter nut has a horizontal line at 0.26 cm.

[0030] Furthermore, the base column 1, the bracket 4 and the support leg 8 are all made of stainless steel. At the same time, the first screw 2 and the second screw 6 and the corresponding nuts 3 and 7 are also made of stainless steel.

[0031] The working principle of the hole punch of this utility model is as follows: before drilling, the approximate hole distribution is calculated based on the diameter of the culture dish. First, the scale and height of the second screw on the bracket are adjusted so that the punching structure composed of the bracket and the second screw maintains the same scale size, and then the nuts of each screw are tightened. When the hole punch is inserted while pouring the agar plate, it is removed after cooling to obtain a plate with five holes around the perimeter and one hole in the center. This agar plate hole punch eliminates the steps of sealing the bottom and selecting the agar after drilling, while also ensuring that the six holes are evenly and beautifully distributed.

[0032] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the methods and technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
