[0025] Please see Figure 1-7 This utility model provides a technical solution: a precision test plate for easy comparison of effects, including a base plate 1 and several test plate bodies 3. The top of the base plate 1 is fixedly intercepted by a fixing groove 2. The test plate bodies 3 are inserted into the inner cavity of the fixing groove 2. A movable plate 5 is provided on the front side of the test plate body 3. A first rubber head 6 is fixedly connected to the rear side of the movable plate 5. The rear side of the first rubber head 6 is in contact with the front side of the test plate body 3. Several grooves 4 are opened on the front side of the fixing groove 2. The movable plate 5 is movably inserted into the inner cavity of the adjacent grooves 4. A first connecting plate 7 is fixedly connected to the bottom of the movable plate 5 near the center position. A second connecting plate 8 is provided on both the left and right sides of the first connecting plate 7. A pin 9 is passed through the first connecting plate 7. The pin 9 and the first connecting plate 7 are rotatably connected. The two ends of the pin 9 are fixedly passed through the adjacent second connecting plates 8. The second connecting plates 8 are fixedly connected to the front side of the fixing groove 2. The cross-section of the second connecting plate 8 is L-shaped.

[0026] A second rubber head 10 is provided near the front of the movable plate 5. The second rubber head 10 is in contact with the bottom of the movable plate 5. A movable frame 11 is fixedly connected to the bottom of the second rubber head 10. A limiting plate 12 is provided on the inner side of the movable frame 11. A fixing rod 13 is fixedly connected to the bottom of the limiting plate 12. A through hole 14 is opened at the bottom of the movable frame 11. The bottom end of the fixing rod 13 movably passes through the through hole 14 and is movably fitted with a spring 15. The fixing rod 13 is fixedly connected to the top of the base plate 1.

[0027] Working Principle: This utility model provides a precision test plate for easy comparison. During use, when comparing multiple test plates, first press down on the front side of the movable plate 5. The movable plate 5 drives the first connecting plate 7 to rotate around the pin 9. The movable plate 5 then presses down on the second rubber head 10, which in turn moves the movable frame 11 along the outer edge of the fixed rod 13. As the movable frame 11 moves, it compresses the spring 15, causing the movable plate 5 to flip upwards away from the groove 4. Then, the test plate body 3 is inserted into the inner cavity of the fixed groove 2, and the rear side of the test plate body 3... The movable plate 5 is then slowly released from its force, and the movable frame 11 and the second rubber head 10 move upward under the elastic action of the spring 15. The second rubber head 10 drives the movable plate 5 to flip, and the movable plate 5 drives the first connecting plate 7 to rotate around the pin 9. The movable plate 5 flips to insert into the inner cavity of the groove 4 until the movable plate 5 drives the first rubber head 6 to flip and fit against the front side of the test plate body 3, thereby fixing the test plate body 3. Multiple test plate bodies 3 are fixed in the above way, which facilitates comparative observation.

[0028] The device compresses the movable plate 5 downwards, causing it to flip away from the groove 4. Then, the test plate body 3 is placed in the inner cavity of the fixed groove 2. After releasing the force on the movable plate 5, the movable plate 5 flips under the action of the spring 15. The movable plate 5 drives the first rubber head 6 to flip and fit against the test plate body 3, thereby fixing the test plate body 3. This device fixes multiple test plate bodies 3 in the inner cavity of the fixed groove 2, which is convenient for comparative observation and is simple to operate.
