Specific embodiments

[0021] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model in conjunction with the attached drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. For the convenience of narration, words such as "upper", "lower", "left", and "right" hereinafter only represent the same directions as the upper, lower, left, and right directions of the attached drawings itself, and do not limit the structure.

[0022] Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments of the following disclosure.

[0023] Embodiment, such as Figures 1 to 6As shown in the figure, the utility model provides a bark collection device for the research on the prevention and control of pests and diseases of ginkgo trees, including a handle 1, and a blade assembly 2 is arranged at the end of the handle 1. Specifically, the blade assembly 2 includes a U-shaped tool rest 21. At the front end of the tool rest 21, there is a main blade 22. The main blade 22 is of an arc structure and the direction of its center is away from the handle 1. The main blade 22 becomes thicker from bottom to top. At the bottom of the main blade 22, there is an arc-shaped cutting edge 23. At both ends of the main blade 22, there are guard plates 24 integrally welded with the tool rest 21. At the bottom of the tool rest 21 close to the handle 1, there is a secondary blade 25. The secondary blade 25 is of an arc structure and its thickness gradually narrows from both sides to the middle. On the side of the secondary blade 25 facing the main blade 22, there is an arc-shaped bevel edge 26. On the tool rest 21 in the direction close to the handle 1, there are two connecting shafts 27. A multifunctional roller assembly 3 that cooperates with the tool rest 21 is rotatably arranged on the connecting shafts 27. The multifunctional roller assembly 3 is used to guide the sample cut by the main blade 22 and is used to manually apply pressure to the secondary blade 25.

[0024] In this device, the guard plates 24 located at both ends of the main blade 22 can play a balancing role, provide strength support for the main blade 22, and can effectively support both sides in the cutting direction to ensure the stability of the cutting direction of the main blade. The main blade 22 is used to cut and sample from the tree trunk. After its cutting edge 23 is sharpened, it has the cutting ability and can cooperate with the cylindrical surface of the tree trunk. Finally, a rectangular long strip incision is formed. For example, when holding the handle 1, the main blade 22 can be tilted against the sampled tree trunk, and pulling down the main blade 22 can cut the bark to achieve sampling. Moreover, the cutting distance, that is, the sampling area, can be flexibly controlled to meet the needs of the research on the lesions at this position. Pressing down the secondary blade 25 makes the main blade 22 leave the tree trunk in a lever manner, and pushing up the secondary blade 25 can cut off the sample, thus completing the bark sampling. Further, when the multifunctional roller assembly 3 is flipped around the connecting shaft 27 to the direction of the main blade 22, it can be used as a sample export structure, so that the cut bark can be exported from behind the main blade 22 and in front of the multifunctional roller assembly 3. If it is flipped to the direction of the secondary blade 25, it can act as a pressure wrench, making the bevel edge 26 better press on the root of the sample, improving the efficiency of cutting off the sample, and further improving the sampling efficiency.

[0025] In order to improve the utilization rate of the multifunctional roller assembly 3, the multifunctional roller assembly 3 provided by the present utility model includes a rotating flap 31 axially connected to a connecting shaft 27. On one side of the rotating flap 31 facing the tool rest 21, there is a two-way braking groove 32 that cooperates with the top edge of the tool rest 21. On the outer side of the rotating flap 31, there is a compression spring piece 33 that elastically cooperates with the side edge. Between the tops of the two rotating flaps 31, there is a roller shaft 34. Among them, the compression spring piece 33 can exert pressure on the rotating flap 31 to make the two-way braking groove 32 brake forward, and the normal state of the roller shaft 34 is the export state, that is, it forms a rolling surface for exporting the sample with the main blade 22; by flipping the rotating flap 31 backward, the two-way braking groove 32 brakes backward, and the roller shaft 34 is located obliquely above the auxiliary blade 25, which is convenient for manually pressing on the auxiliary blade 25.

[0026] Further, the two-way braking groove 32 includes a front notch 321 and a rear notch 322. The front notch 321 and the rear notch 322 are connected to form an L shape. Flipping the rotating flap 31 forward can make the front notch 321 press on the top surface of the tool rest 21, and flipping the rotating flap 31 backward can make the rear notch 322 press on the top surface of the tool rest 21, thereby defining the limit positions in two directions and enabling the multifunctional roller assembly 3 to fully exert the functions of sample export and manual pressing.

[0027] In order to improve the practicality of the compression spring piece 33, the compression spring piece 33 provided by the present utility model includes a connecting section 331 connected to the rear end of the tool rest 21. On the connecting section 331, there is a pressing tongue section 332 located on one side of the tool rest 21. The pressing tongue section 332 is in contact and cooperation with the rear side of the rotating flap 31, and the pressing tongue section 332 is used to exert an elastic restoring force on the rotating flap 31, so that the roller shaft 34 can realize rolling support for the sample and facilitate the stable export of the sample.

[0028] In order to improve the structural strength of the tool rest 21, the present utility model is provided with a reinforcing rib 4 on the outer side of the tool rest 21.

[0029] In order to improve the utilization rate of the present device, the handle 1 in the present utility model adopts a telescopic structure, which is a telescopic rod.

[0030] The above is only the preferred embodiment of the present utility model, and it is not a limitation to the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model.
