The working principle of the rivet nut is as follows:
in the initial state, as shown in fig. 5 and fig. 15, the loaded rivet nut connector 21 is at the extreme position of the rear end, and the length of the thread engagement between the transmission member 3 and the transmission member 2 is designed so that the rivet nut connector 21 will stop moving axially after the rivet nut connector follows the transmission member 3 to the extreme position, and the threads of the transmission member 3 and the transmission member 2 are always in the initial state of engagement under the action of the spring 28 and the valve core 27 inside the transmission member 3; meanwhile, the pull ring 15 is completely positioned in the radial gap 16 of the side handle 8, and the front end of the positioning column 10 is positioned in the positioning hole 9 of the cylindrical handle 1 under the action of the compression spring 14, so that the cylindrical handle 1 and the safety side handle 5 are in a mutually fixed rigid connection state;
in an initial state, as shown in fig. 6 and fig. 15, the rotating part 2 is connected with the driving device, and a steering direction which can enable the transmission part 3 to extend forwards is selected, so that the rotating part 2 rotates along with the driving device, the transmission part 3 is pushed to move forwards under the action of thread transmission until the rivet nut connector 21 extends completely, and the rotating part 2 and the transmission part 3 are disengaged from thread engagement;
in the next state, as shown in fig. 7 and 16, the pull ring 15 is integrally pulled out of the radial gap 16 of the side handle 8, and is rotated by a certain angle, so that the pull ring is stably clamped on the end surface of the side handle 8, the positioning column 10 moves downwards along with the pull ring 15, the front end of the positioning column leaves the positioning hole 9 of the tubular handle 1, so that the tubular handle 1 and the safety side handle 5 are separated, and the two can rotate relatively;
in the last state, as shown in fig. 8 and 16, the steering of the driving device is changed, because the cylindrical handle 1 and the safety side handle 5 are separated, and a set of bearings 17 is arranged, the cylindrical handle 1 can carry the front rivet nut connector 21 to smoothly rotate along with the driving device, in the process, the corresponding rivet nut can be attached to the front end thread of the rivet nut connector 21, and the rivet nut can be engaged and assembled on the rivet nut connector 21 along the thread until the rivet nut is installed in place;
in the last state, as shown in fig. 9 and 17, the pull ring 15 is rotated and retracted into the radial notch 16 of the side handle 8, and the positioning column 10 moves upward under the action of the compression spring 14 until contacting the cylindrical handle 1, but since the cylindrical handle 1 rotates along with the driving device in the last step, the front end of the positioning column 10 has a large probability of contacting the outer cylindrical surface of the cylindrical handle 1, since the rotating member 2 and the thread of the transmission member 3 have good lubrication, the cylindrical handle 1, the outer cylindrical surface are supported by the positioning column 10, there is a rotation stopping stage with small resistance, the driving device continues to drive the rotating member 2, the cylindrical handle 1 does not rotate along with the rotation, and instead, the rivet nut connector 21 and the transmission member 3 move backward under the action of the thread of the rotating member 2 until the end surface of the rivet nut is flush with the end surface of the guide nozzle assembly 20;
in the last state, as shown in fig. 10 and fig. 15, at this time, the tubular handle 1 and the safety side handle 5 can rotate relatively, the driving device continues to drive the rotating member 2, because the pulling force of the riveting rivet nut is far greater than the resistance generated when the positioning column 10 abuts against the outer cylindrical surface of the tubular handle 1, the tubular handle 1 will rotate along with the driving device until the positioning hole 9 on the tubular handle 1 is aligned with the positioning column 10, and the front end of the positioning column 10 enters the positioning hole 9 of the tubular handle 1 under the action of the compression spring 14, so that the tubular handle 1 and the safety side handle 5 become almost rigidly connected again, and at the same time, a sound of "resetting" is given to remind the user that the user has been reset and injured due to improper use;
in the previous state, as shown in fig. 11 and 15, the rivet nut has completed the pre-riveting work, the rivet nut is vertically placed into the hole of the riveting member, the side handle 8 is held and the trigger is continuously pulled, the rivet nut connector 21 and the transmission member 3 move backwards together under the driving of the thread of the rotating member 2, so that the rivet nut is deformed by pulling until the riveting process is completed;
in the previous state, as shown in fig. 12 and 15, the driving device is changed in rotation direction to push the rivet nut connector 21 forward by a suitable length;
in the last state, as shown in fig. 14 and 16, the pull ring 15 is pulled out of the radial gap 16 of the side handle 8 and rotated by a certain angle to be clamped on the end surface of the side handle 8, so that the cylindrical handle 1 and the safety side handle 5 are separated again, as shown in fig. 13 and 16, the driving device is continuously driven to drive the rotating member 2, and the direction of the cylindrical handle 1 is adjusted, so that the thread at the front end of the rivet nut connector 21 is not tightly attached to the inner thread of the rivet nut, the friction force generated by the friction force is smaller than the force generated by the threaded engagement of the rotating member 2 and the transmission member 3, and the rivet nut connector 21 and the cylindrical handle 1 rotate together with the driving device and are released from the threaded engagement of the rivet nut, so that one riveting action is completed;
after the previous action is completed, the state of fig. 7 is restored, and if the extending length of the rivet nut connector 21 is suitable, a new rivet nut can be directly installed, and a new riveting is performed.
