[0029] To keep the following description of the embodiments of the present utility model clear and concise, the detailed descriptions of known functions and known components are omitted in the present utility model.

[0030] Embodiment 1

[0031] Please refer to Figures 1-4 As shown, in this embodiment, a coater is provided, including: a support rod 1, a coating head 2, a locking component, and an adjusting component;

[0032] Specifically, the support rod 1 serves as the main structure, and a rotating frame 7 is fixedly installed at one end thereof for supporting and rotating the coating head 2.

[0033] The coating head 2 is designed in a triangular shape and is composed of a coating rod and two connecting rods. Such a design is beneficial for evenly coating the bacterial solution. One ends of the two connecting rods are fixedly installed together with a rotating block 8. The rotating block 8 is rotatably connected to the rotating frame 7 through a clamping structure of a clamping column, enabling the coating head 2 to flexibly adjust its angle.

[0034] To limit the rotation angle of the coating head 2, a locking component is designed in this embodiment. The locking component includes an abutting rod 4 slidably disposed inside the support rod 1. One end of the abutting rod 4 slidably penetrates one end of the support rod 1 and the rotating frame 7, and the other end is fixedly installed with a spring 6. The other end of the spring 6 is fixedly connected to the inner wall of one side of the support rod 1 to provide a restoring force for the abutting rod 4. A plurality of card slots 12 are formed on the outer wall of the rotating block 8, and these card slots 12 cooperate with one end of the abutting rod 4; when one end of the abutting rod 4 is caught in any one of the card slots 12, the rotation of the rotating block 8 can be restricted, and thus the angle of the coating head 2 can be fixed.

[0035] In addition, an adjusting component is designed in this embodiment to assist in the rotation adjustment of the coating head 2. The adjusting component includes two fixing rods 13 fixedly installed on the outer wall of the rotating block 8. One of the fixing rods 13 is rotatably connected to a traction spring 11 through a hook. The traction spring 11 is used to complete the pushing and pulling traction of the fixing rod 13. The other end of the fixing rod 13 is fixedly connected to an installation collar 9. The installation collar 9 is slidably sleeved on the outer wall of the support rod 1. One side of the installation collar 9 is rotatably connected to an internally threaded collar 10. The internally threaded collar 10 is also sleeved on the outer wall of the support rod 1 and is threadedly connected to a threaded section formed on the outer wall of the support rod 1; by rotating the internally threaded collar 10, the installation collar 9 can be pushed to move axially along the support rod 1, and then the rotating block 8 and the coating head 2 can be driven to rotate through the traction spring 11 and the fixing rod 13 to achieve angle adjustment.

[0036] This application can be used in the technical field of microbiological experimental equipment and can also be used in other fields applicable to this application.

[0037] Embodiment 2

[0038] Refer toFigure 2 , 3 , based on the improvement of Example 1: a microbial liquid applicator, which is applied to the technical field of microbial experimental equipment;

[0039] In order to facilitate the operation of the locking assembly, a lever 5 is also fixedly installed on the outer wall of the abutment rod 4. One end of the lever 5 passes through the outer wall of the support rod 1 and slides in an adjustment groove opened on the outer wall of the support rod 1. By pulling the lever 5 outward, the abutment rod 4 can be pushed to compress the spring 6 and disengage from the slot 12, thereby releasing the lock on the rotating block 8 and allowing the coating head 2 to rotate freely.

[0040] In order to improve the comfort of use, a handle 3 is fixedly sleeved on the end of the support rod 1 away from the coating head 2. The handle 3 is made of anti-slip materials such as rubber, which is convenient for users to hold stably and operate.

[0041] In order to further facilitate the user to operate the internal threaded ring 10, the present embodiment adds a plurality of protrusions on the outer wall of the internal threaded ring 10. These protrusions not only increase the friction of the outer wall of the internal threaded ring 10, but also provide the user with a better fulcrum, making it easier to rotate the internal threaded ring 10 and less prone to slipping.

[0042] The use process and working principle of the technical solution of this utility model are as follows:

[0043] When in use, the user can adjust the angle between the coating head 2 and the support rod 1 as needed to facilitate uniform coating of the microbial liquid; in the coating device, the coating head 2 is connected to the rotating frame 7 by the rotating block 8 to complete the angle adjustment with the support rod 1; when it is necessary to adjust the rotation angle of the coating head 2, first, the user can disengage the abutment rod 4 from the slot 12 by toggling the toggle lever 5, thereby releasing the locking state of the rotating block 8, and then the user can rotate the internal threaded collar 10, and use the threaded connection between the internal threaded collar 10 and the threaded section of the outer wall of the support rod 1 to make the coating head 2 rotate. The internal threaded ring 10 moves axially along the support rod 1. The movement of the internal threaded ring 10 will drive the movement of the mounting ring 9 and the fixing rod 13, and then drive the rotating block 8 and the coating head 2 to rotate accordingly through the traction of the traction spring 11; when the coating head 2 is adjusted to the desired angle, release the lever 5, and the elastic force of the spring 6 will push the abutment rod 4 back to its original position, so that it will be re-engaged in the groove 12 on the outer wall of the rotating block 8. The cooperation between the abutment rod 4 and the groove 12 can complete the locking of the rotating block 8, thereby ensuring that the coating head 2 maintains a stable rotation angle during the coating process.
