[0017] This utility model provides a blade sharpness tester with a reciprocating structure.

[0018] Please see Figure 1 It includes a main base plate 1 and a main support plate 2. The upper surface of the main base plate 1 is fixedly connected to a blade protective shell 19. The purpose of setting the blade protective shell 19 is to achieve the protective effect and prevent accidental contact with the blade body 20 during operation. At the same time, it facilitates the installation and testing of the blade body 20. The blade protective shell 19 is inserted into the blade body 20, and the blade body 20 is compatible with the slot of the blade protective shell 19.

[0019] Please see Figure 1 and Figure 2The main support plate 2 is fixedly connected to the upper surface of the main base plate 1 by an L-shaped bracket 18. The purpose of setting the L-shaped bracket 18 is to effectively support the main support plate 2, so that the main support plate 2 can be suspended. The main support plate 2 is fixedly connected to a control display 21. The purpose of setting the control display 21 is to control the DC motor 3 and pressure sensor 12 in this application. The control display 21 is electrically connected, which facilitates the user to operate the tester of this application. The control display 21, DC motor 3 and pressure sensor 12 are all existing public technologies. This application will not elaborate on the working principle, appearance, etc. of the three.

[0020] Please see Figure 2 and Figure 5 A DC motor 3 is fixedly connected to one side of the main support plate 2. The output shaft of the DC motor 3 is fixedly connected to the control slide plate 4. The purpose of setting the DC motor 3 is to provide sufficient power support for the rotation of the control slide plate 4 and ensure that the control slide plate 4 can move smoothly.

[0021] Please see Figure 4 and Figure 5 The inner wall of the control plate 4 is slidably connected to a linkage cam 5. The linkage cam 5 is slidably connected in a limiting groove 6 opened in the main support plate 2. The linkage cam 5 is controlled by both the control plate 4 and the limiting groove 6. The limiting groove 6 can provide power support for the movement of the linkage cam 5, while the limiting groove 6 can control the movement position of the linkage cam 5.

[0022] Please see Figure 4 and Figure 5 The linkage cam 5 is rotatably connected to one side of the mounting part 7. The mounting part 7 can apply a control effect to the linkage cam 5 to ensure that the linkage cam 5 can rotate in place and will not fall off. In addition, the setting of the linkage cam 5 can reduce the frictional resistance between the components. The bottom of the mounting part 7 is fixedly connected to the linkage part 8. The mounting part 7 and the linkage part 8 are integrated designs and maintain the linkage effect.

[0023] Please see Figure 1 and Figure 3 One end of the linkage component 8 is fixedly connected to the control housing 11. The linkage component 8 and the control housing 11 are in a direct connection state, and the two maintain the linkage effect. The inner wall of the control housing 11 is slidably connected to the linkage slide plate 13. The setting of the control housing 11 can apply the control effect to the linkage slide plate 13, ensuring that the linkage slide plate 13 can only move vertically up and down within the control housing 11.

[0024] Please see Figure 3A U-shaped bracket 15 is fixedly connected to one side of the linkage slide plate 13. The linkage slide plate 13 and the U-shaped bracket 15 are directly connected and maintain the linkage effect. There are two U-shaped brackets 15. The setting of two U-shaped brackets 15 can effectively support the test paper. At this time, the test paper is between the two U-shaped brackets 15.

[0025] Please see Figure 3 Two U-shaped brackets 15 are respectively fixedly connected to threaded plates 16. The inner wall of the threaded plate 16 is threaded with fixing bolts 17. The purpose of setting the fixing bolts 17 is that by rotating the fixing bolts 17, the position of the fixing bolts 17 will change, thereby the fixing bolts 17 can strongly press the test paper to ensure the stability of the test paper and prevent it from falling off.

[0026] Please see Figure 3 A resilient spring 14 is fixedly connected to the top of the linkage slide plate 13. One end of the resilient spring 14 is fixedly connected to the inner wall of the control housing 11. The purpose of setting the resilient spring 14 is to use the rebound characteristic of the resilient spring 14 to make the linkage slide plate 13 stably reset.

[0027] Please see Figure 3 A pressure sensor 12 is fixedly connected to the inner wall of the control housing 11. The pressure sensor 12 is in contact with the linkage slide plate 13. When the linkage slide plate 13 rises, it can apply pressure to the pressure sensor 12. The pressure sensor 12 then transmits the data to the control display 21, so that the sharpness data of the blade body 20 can be obtained.

[0028] Please see Figure 1 and Figure 4 The linkage 8 is slidably connected to the inner wall of the control component 9. The purpose of setting the control component 9 is to effectively control the linkage 8, ensuring that the linkage 8 can move up and down within the control component 9 without the phenomenon of component separation. The control component 9 is slidably connected to the outer wall of the dovetail track 10. The purpose of setting the dovetail track 10 is to effectively control the control component 9, so that the control component 9 can only move left and right in the horizontal direction. The dovetail track 10 is fixedly connected to the other side of the main support plate 2.

[0029] Working principle: During use, the blade body 20 to be tested is placed inside the blade protective shell 19 beforehand. Then, the test paper is placed between the two U-shaped brackets 15. By manually rotating the fixing bolts 17, the test paper can be reinforced to ensure its stability. The test paper is also horizontally staggered away from the blade body 20 to prevent the user from accidentally touching the blade body 20 during the installation of the test paper, thus improving the safety factor. Then, the DC motor 3 is controlled to rotate forward by the control display 21. The DC motor 3 will drive the control slide plate 4 to move. At this time, the control slide plate 4 applies a force to the linkage cam 5. The linkage cam 5 is restricted by the limit groove 6, causing the linkage cam 5 to slide within the control slide plate 4. At the same time, the linkage cam 5 will drive the linkage 8 to slide within the control component 9 through the mounting part 7. At this time, the control component 9 will translate outside the dovetail track 10. Therefore, the linkage 8 drives the control component 9 to slide outside the dovetail track 10. The shell 11 moves in an arc, allowing the test paper to smoothly enter the blade protective shell 19 and contact the blade body 20. As it continues to move, the reaction force causes the test paper to move upward through the threaded plate 16 and the fixing bolt 17, which in turn causes the linkage slide plate 13 to apply pressure to the pressure sensor 12 until the test paper breaks due to the blade body 20. At this point, the pressure application stops, and the linkage slide plate 13 quickly resets under the action of the toughness spring 14. At this time, the pressure sensor 12 transmits the test data to the control display 21. After processing the information, the control display 21 displays the sharpness test result of the blade body 20. Similarly, after the test is completed, the DC motor 3 reverses, which resets the control shell 11, making it easy to remove the broken test paper. This achieves the purpose of reciprocating movement and solves the problem that the hand can easily touch the blade body 20 when disassembling and assembling the test paper.
