Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4The utility model provides a fastener fastening state detection structure, comprising: a carrier 1, a motor 2 installed on the outer wall of one side of the carrier 1, a first mounting plate 3 and a second mounting plate 4 installed on the outer wall of the motor 2, and also comprising: a torque increasing component 5 rotatably installed on one end of the top of the first mounting plate 3, a rotating column 6 rotatably installed on one end of the bottom outer wall of the second mounting plate 4, and the outer wall of the rotating column 6 is provided with mounting grooves 8 distributed at equal distances, and the inner walls of the mounting grooves 8 are all installed with elastic components 7, and each elastic component 7 is rotatably installed with a first inner hexagon socket 9, a second inner hexagon socket 10, a third inner hexagon socket 11 and a fourth inner hexagon socket 12, and the tops of the first inner hexagon socket 9, the second inner hexagon socket 10, the third inner hexagon socket 11 and the fourth inner hexagon socket 12 are all provided with slots 13.

[0020] It should be noted here that the first hexagon socket 9, the second hexagon socket 10, the third hexagon socket 11 and the fourth hexagon socket 12 can be interchanged by rotating the rotating column 6, and can be used alternately according to screws of different sizes. When the first hexagon socket 9 is selected, the first hexagon socket 9 can be rotated to the bottom of the torque increasing component 5, and the elastic component 7 is provided to facilitate the connection between the first hexagon socket 9 and the bottom of the torque increasing component 5. After the connection, the bottom of the first hexagon socket 9 can be put on the screw nut, and the torque increasing component 5 can be driven to rotate by the motor 2, thereby driving the first hexagon socket 9 to rotate, applying reverse torque to the screw for a certain period of time, and observing whether the screw is loose. The torque increasing component 5 can amplify the torque and reduce the rotation speed, thereby preventing the first hexagon socket 9 from slipping on the nut due to excessive rotation.

[0021] In a preferred embodiment, the torque increasing assembly 5 includes a rotating rod 501, a first gear 502 fixed on the outer wall of the rotating rod 501, a second gear 503 meshing with the first gear 502, a dial 504 fixed on the outer wall of the rotating rod 501 and an insert plate 505 installed at the bottom of the rotating rod 501, and the second gear 503 is fixed on the output shaft of the motor 2.

[0022] It should be noted here that the insert plate 505 can be inserted into the slot 13 at the top of the first hexagonal socket 9, and the motor 2 can drive the second gear 503 to rotate, thereby driving the first gear 502 and the rotating rod 501 to rotate, and then driving the insert plate 505 and the first hexagonal socket 9 to rotate.

[0023] In a preferred embodiment, the elastic component 7 includes a sliding rod 701 , a spring 702 sleeved on the sliding rod 701 , a slider 703 sleeved on the sliding rod 701 , and a movable plate 704 fixed on an outer wall of one side of the slider 703 .

[0024] It should be noted here that: in the process of rotating the first hexagon socket 9 to the bottom of the plug plate 505, the first hexagon socket 9 can be pulled downward, driving the movable plate 704 and the slider 703 to descend, while squeezing the spring 702. When the first hexagon socket 9 is rotated to the bottom of the plug plate 505, the first hexagon socket 9 is released. Under the action of the spring 702, the first hexagon socket 9 is reset and raised, so that the plug plate 505 is inserted into the slot 13 at the top of the first hexagon socket 9 to complete the connection.

[0025] In a preferred embodiment, a pointer 14 is fixed to one end of the bottom outer wall of the first mounting plate 3 , and an annular scale line is engraved on the top outer wall of the dial 504 .

[0026] It should be noted here that: when the screw is not installed tightly and rotates loose due to torque, the dial 504 will rotate with the rotating rod 501, and the number of the circular scale line corresponding to the bottom of the pointer 14 will change, which is convenient for directly observing the looseness of the screw.

[0027] In a preferred embodiment, the hexagonal notches at the bottoms of the first hexagonal socket 9, the second hexagonal socket 10, the third hexagonal socket 11 and the fourth hexagonal socket 12 are enlarged in sequence.

[0028] It should be noted here that it is convenient to replace screws of different sizes.

[0029] In a preferred embodiment, the gear ratio between the first gear 502 and the second gear 503 is 3:1.

[0030] It should be noted that the second gear 503 drives the first gear 502 to rotate, which can achieve the effect of reducing speed and increasing torque.

[0031] Working principle: the first hexagon socket 9, the second hexagon socket 10, the third hexagon socket 11 and the fourth hexagon socket 12 can be interchanged by rotating the rotating column 6, and can be used alternately according to screws of different sizes. When the first hexagon socket 9 is selected, the first hexagon socket 9 can be rotated to the bottom of the plug plate 505. In the process of rotating the first hexagon socket 9 to the bottom of the plug plate 505, the first hexagon socket 9 can be pulled downward to drive the movable plate 704 and the slider 703 to descend, and at the same time squeeze the spring 702. When the first hexagon socket 9 is rotated to the bottom of the plug plate 505, the first hexagon socket 9 is released. Under the action of the spring 702, the first hexagon socket 9 is reset and raised, so that the plug plate 505 is inserted into the slot 13 at the top of the first hexagon socket 9 to complete the connection;

[0032] The bottom of the first hexagon socket 9 can be put on the screw nut, and the second gear 503 can be driven to rotate by the motor 2, thereby driving the first gear 502 and the rotating rod 501 to rotate, and then driving the plug plate 505 and the first hexagon socket 9 to rotate, and applying a reverse torque to the screw for a certain period of time to observe whether the screw is loose. The second gear 503 drives the first gear 502 to rotate, which can have the effect of slowing down and increasing torque, and prevent the first hexagon socket 9 from slipping on the nut due to excessive rotation. When the screw is not installed tightly and rotates loose due to torque, the dial 504 will rotate with the rotating rod 501, and the number of the annular scale line corresponding to the bottom of the pointer 14 will change, so that it is convenient to directly observe the looseness of the screw.
