[0028] The card-connecting installation mechanism includes a square block 6, a slider 7, a spring 1 8, a T-block 9, a card block 10, a card slot 11 and a spring 2 12. Four strip grooves are evenly arranged at the top of the diagnostic box 1. A spring 1 8 is fixedly installed inside the strip groove, and the other end of the spring 1 8 is fixedly installed on the slider 7. The slider 7 is slidably installed inside the strip groove. A square block 6 is fixedly installed on the top of the slider 7. The bottom end of the square block 6 fits with the top of the protective plate 5. A T-block 9 is slidably installed on the top of the square block 6. A spring 2 12 is installed on the annular side of the T-block 9, and the two ends of the spring 2 12 fit with the T-block 9 and the square block 6 respectively. The bottom end of the T-block 9 passes through the square block 6, and a card block 10 is fixedly installed at the bottom of the square block 6. The card block 10 is stored at the bottom of the square block 6. A card slot 11 is arranged inside the strip groove. During operation, the user pulls the square block 6, and the movement of the square block 6 drives the slider 7 to move along the strip groove, thereby pressing the spring 1 8. The square block 6 moves to drive the card block 10 to move. When the card block 10 is aligned with the square through slot on the card slot 11, the T-block 9 is pushed downward. The T-block 9 moves downward to drive the card block 10 to move through the square through slot into the cylindrical slot. The T-block 9 moves to squeeze the spring 2 12, and then the T-block 9 is rotated. The T-block 9 rotates to drive the card block 10 to rotate and fit the inner wall of the cylindrical slot.

Inside the card slot 11, fix the position of the square block 6, install the protection plate 5 on the top of the transparent glass plate 4, so that the top of the protection plate 5 is flush with the top of the diagnostic box 1, rotate the T-block 9 in the opposite direction, so that the card block 10 is aligned with the square through slot, and under the action of the elastic force of the spring 2 12, the T-block 9 pulls the card block 10 to move out of the card slot 11, and under the action of the elastic force of the spring 1 8, the slider 7 moves to drive the square block 6 to move back to fit the top of the protection plate 5, thereby completing the installation of the protection plate 5.

[0029] The card slot 11 consists of a square through slot and a cylindrical slot. A square through slot is opened at the bottom end of the strip slot, and a cylindrical slot is opened inside the diagnostic box 1. The top of the cylindrical slot is connected to the square through slot. The cross-section of the bottom end of the card block 10 is the same as the cross-section of the square through slot. When working, this design facilitates the card block 10 to pass through the square through slot and enter the cylindrical slot.

Two T-shaped blocks 16 are symmetrically fixedly installed at the left end of the blocking cover 3, and one end of the T-shaped block 16 passes through the limiting groove 17 and fits with the left end of the circular ring 24. When working, the T-shaped block 16 is clamped in the limiting groove 17, so as to facilitate the installation of the blocking cover 3 on the air intake pipe 2.

[0032] The limiting groove 17 has a square hole groove and an arc groove, and two square hole grooves and two arc grooves are symmetrically opened at the right end of the circular ring 24, and one end of the arc groove fits in the middle position of the square hole groove; when working, the design of the square hole groove facilitates one end of the T-shaped block 16 to pass through the square hole groove and the circular ring 24, and the design of the arc groove facilitates the T-shaped block 16 to be clamped in the limiting groove 17, so as to realize the installation of the blocking cover 3.

[0033] Two receiving grooves are symmetrically provided at the right end of the circular ring 24, and a spring four 18 is fixedly installed inside the receiving groove. A pressure plate 19 is fixedly installed at one end of the spring four 18, and the right end of the pressure plate 19 is in contact with the left end of the blocking cover 3. During operation, during the installation of the blocking cover 3, the blocking cover 3 squeezes the pressure plate 19, and the pressure plate 19 moves to squeeze the spring four 18. The elastic force of the spring four 18 facilitates the reverse pushing of the blocking cover 3, thereby clamping the T-shaped block 16 in the limiting groove 17.

[0034] The right end of the pressure plate 19 is evenly provided with more than two spherical grooves, and balls are rolled inside the spherical grooves. The spherical side of the balls fits with the left end of the blocking cover 3. When working, the design of the balls reduces the friction between the blocking cover 3 and the ring 24 when rotating.

[0038] Working principle: install the protection plate 5 on the top of the transparent glass plate 4 so that the top of the protection plate 5 is flush with the top of the diagnostic box 1, rotate the T-block 9 in the opposite direction to align the card block 10 with the square through slot, and under the action of the elastic force of spring 2 12, the T-block 9 pulls the card block 10 to move out of the card slot 11, and under the action of the elastic force of spring 1 8, the slider 7 moves to drive the square block 6 to move back to fit the top of the protection plate 5, thereby completing the installation of the protection plate 5.

[0039] During the installation of the blocking cover 3, the design of the square hole groove facilitates one end of the T-shaped block 16 to pass through the square hole groove and the circular ring 24, and the design of the arc groove facilitates the T-shaped block 16 to be clamped in the limiting groove 17. The blocking cover 3 squeezes the pressure plate 19, and the pressure plate 19 moves to squeeze the spring four 18.
