[0040] Specifically, the right side of the rivet is passed through the object to be fixed, and the right side of the rivet flange 11 is pressed against the object. Under this configuration, the core rod 7 is installed according to the tool, and the rotating plate 5 is rotated along the U-shaped block 3, while driving the positioning block 4 and the clamping block 6 thereon to rotate. This process realizes the engagement of the clamping block 6 with the connecting groove 8, and fixes the core rod 7 to the fixing block 1. In this fixed state, pulling the core rod 7 will drive the movement of the connecting rod 9 and the nail head 10. This action enables the nail head 10 to squeeze the expansion part 12, thereby realizing riveting. It should be emphasized that during the entire core pulling process, riveting and fixing can be conveniently performed without using specific tools. This design provides a simple and efficient riveting solution, which is suitable for operation scenarios that do not require special tools.

[0041] Reference Figure 2 and Figure 3The connecting mechanism 2 includes a first threaded column 201, which is fixedly connected to the right side of the connecting rod 9. A first threaded hole 202 is provided on the left side of the nail head 10. The first threaded column 201 is threadedly connected to the first threaded hole 202. A second threaded column 203 is fixedly connected to the right side of the fixing block 1. A second threaded hole 204 is provided on the left side of the connecting rod 9.

The outer sides of the first threaded column 201 and the second threaded column 203 are both provided with mounting grooves 205.

[0042] Specifically, by fixing the first threaded column 201 and the first threaded hole 202, it is convenient to disassemble and replace different nail heads 10 according to actual needs. At the same time, through the connection between the second threaded column 203 and the second threaded hole 204, the core rod 7 structure can be taken out after riveting is completed without breaking the connecting rod 9. This design facilitates the recycling of rivets and improves the reuse rate of materials.

[0045] Working principle: Before using the device, first pass the right side of the rivet through the object to be fixed, and make the right side of the rivet flange 11 against the object. At this time, install the core rod 7 according to the tool, and by rotating the rotating plate 5 along the U-shaped block 3 and driving the positioning block 4 and the clamping block 6 thereon to rotate, the clamping block 6 can be engaged with the connecting groove 8, and the core rod 7 can be fixed to the fixing block 1. At this time, pull the core rod 7 to drive the connecting rod 9 and the nail head 10 to move, so that the nail head 10 can squeeze the expansion part 12 to achieve riveting. It does not require the use of specific tools during the core pulling process to perform riveting and fixation, thereby reducing the practicality of the device, and by fixing between the first threaded column 201 and the first threaded hole 202, it is convenient to disassemble and replace different nail heads 10 according to actual needs, and through the connection between the second threaded column 203 and the second threaded hole 204, the core rod 7 structure can be taken out after riveting is completed, without breaking the connecting rod 9, so as to facilitate the recovery of the rivet, thereby improving the reliability of the device.
