Description

Technical Field

[0001] This utility model relates to a special sampling knife, belonging to the field of medical devices. Background Technology

[0002] To test the sealing strength of medical heat-sealed bags, an area of ​​the appropriate width needs to be cut from the heat-sealed bag and tested on a sealing tensile testing machine. Currently, there are no professional cutting tools available for heat-sealed bags on the market. Utility knives or scissors are often used for cutting, which is not only inconvenient and inefficient, but also results in inconsistent cut sizes each time, affecting the accuracy of the test. Summary of the Invention

[0003] Based on the problems described in the background, the problem to be solved by this utility model is to provide a special sampling knife that, by setting parallel blades and a protective cover, can effectively solve the problems of inefficiency and inconsistent specifications in cutting heat-sealed bags, as well as the problem of avoiding cuts and injuries.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a special sampling knife is provided, including a handle, a knife body, a knife body fixing bolt, a blade, a blade fixing bolt, and a protective cover. The handle is a cylindrical body with one end rounded. The knife body is covered and installed on the other end of the handle. A knife body fixing bolt is provided in the middle of the knife body, and the knife body fixing bolt passes through the handle and the knife body to fix the knife body on the handle. The blade is installed on the other end of the knife body. The blade fixing bolt passes through the knife body and the blade to fix the blade on the knife body. The protective cover is installed on one end of the blade of the knife body and completely covers the blade.

[0005] Preferably, the protective cover is further provided with a rotating bolt, a spring, and a pressing port. The rotating bolt passes through the blade body and the protective cover to rotatably fix the protective cover to the blade body. The spring is installed on the blade body and is located between the blade body and the protective cover. The other end of the spring is installed on the protective cover. The pressing port is opened on the protective cover away from the rotating bolt and above the blade fixing bolt.

[0006] Preferably, the blade body is further provided with a blade mounting port and a spring mounting port. The blade mounting port is located at the intersection of the blade body and the blade and extends through the entire blade body, while the lower end of the blade mounting port does not extend through the blade body. The spring mounting port is located at the mounting position of the blade body and the spring.

[0007] Preferably, the middle part of the handle is also provided with knurling, which facilitates use and increases friction.

[0008] Preferably, the number of blades is multiple and the blades are arranged in parallel, which can cut the required sealing bag sample in one go and avoid multiple cuts.

[0009] Preferably, the number of blade mounting ports is the same as the number of blades.

[0010] Preferably, the protective cover is fully open in the blade direction to facilitate the use of the blade.

[0011] The beneficial effects of this utility model are:

[0012] 1. Equipped with multiple sets of blades, it can cut to the desired bag style in one go, avoiding multiple cuts, and the sealing strips cut each time are of the same size, which is convenient for testing.

[0013] 2. It is equipped with a protective cover. Under the action of the spring, it is normally held in place. When you need to use the blade, you can gently press down the protective cover to avoid cutting injuries.

[0014] 3. The overall structure is simple, making it easy to assemble and maintain. Attached Figure Description

Detailed Implementation

[0019] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0020] Example 1

[0021] like Figures 1-3 As shown, this utility model includes a handle 1, a blade 2, a blade fixing bolt 3, a blade 4, a blade fixing bolt 5, and a protective cover 6. The handle 1 is a cylindrical body with one end rounded. The blade 2 is mounted on the other end of the handle 1. The blade fixing bolt 3 is located in the middle of the blade 2 and passes through the handle 1 and the blade 2 to fix the blade 2 to the handle 1. The blade 4 is mounted on the top of the other end of the blade 2. The blade fixing bolt 5 passes through the blade 2 and the blade 4 to fix the blade 4 to the blade 2. The protective cover 6 is mounted on one end of the blade 4 of the blade 2 and completely covers the blade 4.

[0022] When using it, simply open the protective cover 6, align it with the style of the resealable bag that needs to be cut, and cut it. This avoids multiple cuts and can be completed in one go, with the sealing strips being the same size.

[0023] It is rather inconvenient to open the protective cover 6 separately during use, so the protective cover 6 is also equipped with a rotating bolt 7, a spring 8, and a pressing port 9. The rotating bolt 7 passes through the blade body 2 and the protective cover 6 to rotatably fix the protective cover 6 to the blade body 2. The spring 8 is installed on the blade body 2 and is located between the blade body 2 and the protective cover 6. The other end of the spring 8 is installed on the protective cover 6. The pressing port 9 is opened on the protective cover 6 away from the rotating bolt 7 and is located above the blade fixing bolt 5.

[0024] After installation, there is no need to open the protective cover 6. Under normal circumstances, the protective cover 6 will be held in place by the action of the spring 8. When using it, simply press the protective cover 6 gently, and the blade 4 will be exposed, and then you can make the cut.

[0025] To facilitate the installation of the blade 4 and the spring 8, the blade body 2 is also provided with a blade mounting port 10 and a spring mounting port 11. The blade mounting port 10 is located at the intersection of the blade body 2 and the blade 4, and the blade mounting port 10 penetrates the entire blade body 2. However, the lower end of the blade mounting port 10 does not penetrate the blade body 2. The spring mounting port 11 is located at the installation position of the blade body 2 and the spring 8.

[0026] For ease of use, the middle part of the handle 1 is also knurled to increase friction.

[0027] To avoid multiple cuts, the number of blades 4 is multiple and they are arranged in parallel, so that the required sealing bag sample can be cut in one go.

[0028] The number of blade mounting ports 10 is the same as the number of blades 4.

[0029] The protective cover 6 is fully open in the direction of the blade 4 for easy use of the blade.
