[0026] In one possible implementation, a spring ball 610 is also included, which is disposed at the bottom of the floating ring 600 and is arranged in a ring structure around the floating ring 600.

[0027] Specifically, such as Figure 1 As shown, in order to enable the floating ring 600 to work properly, a spring ball 610 is set at the bottom of the floating ring 600. The spring ball 610 is set as a ring structure, with a left and right floating distance of 1.5mm and an angle floating of 3°.

[0029] Specifically, such as Figure 1 As shown, in order to prevent the rivet 500 from falling off during operation, a limiting sleeve 620 is provided. The limiting sleeve 620 is a hollow structure with openings at the top and bottom, so that the rivet 500 can pass through the limiting sleeve 620.

[0035] Specifically, such as Figure 1 As shown, depending on the actual situation, it is necessary to replace the rivet 500. To facilitate the replacement of the rivet 500, a thrust sleeve 640 and a rivet replacement part 650 are provided. The rivet 500 passes through the thrust sleeve 640, and the rivet replacement part 650 is sleeved on the rivet 500. When the rivet 500 needs to be replaced, the plunger 630 is manually pressed, the limit sleeve 620 is rotated and removed, the thrust sleeve 640 is manually pushed, the rivet replacement part 650 is compressed, and the rivet 500 is rotated and removed. After the replacement is completed, the rivet replacement part 650 is compressed and automatically resets. Preferably, the rivet replacement part 500 is made of spring.

[0036] In one possible implementation, an upper riveting motor 700 and a lower riveting motor 800 are also included; the upper riveting motor 700 is disposed at the bottom of the housing 100 and is electrically connected to the transmission rod 200; the lower riveting motor 800 is disposed on one side of the upper riveting motor 700 and is electrically connected to the planetary screw 300.

[0037] Specifically, such as Figure 1 As shown, in order to enable the overall operation, an up riveting motor 700 and a pull riveting motor 800 are provided to supply power to the whole. The up riveting motor 700 is electrically connected to the transmission rod 200 to provide power for the up riveting, and the pull riveting motor 800 is electrically connected to the planetary screw 300 to provide power for the pull riveting.

[0038] In one possible implementation, it also includes an input gear 810, a transmission gear 820, and an output gear 830; the input gear 810, the transmission gear 820, and the output gear 830 are connected in sequence, the input gear 810 is mounted on the riveting motor 800 and electrically connected to the riveting motor 800; the output gear 830 is connected to the transmission gear 820 and the planetary screw 300 respectively.

[0039] Specifically, such as Figure 1 As shown, in order to ensure that the planetary screw 300 can move up and down, an input gear 810, a transmission gear 820 and an output gear 830 are provided. After the input gear 810 receives the load, it rotates, which in turn drives the transmission gear 820 and the output gear 830 to rotate first, and further drives the planetary screw 300 to move up and down.

[0040] In one possible implementation, a coupling 710 is also included, which is disposed between the riveting motor 700 and the transmission rod 200.

[0041] Specifically, such as Figure 1 As shown, in order to better connect the riveting motor 700 and the transmission rod 200, a coupling 710 is installed directly between the riveting motor 700 and the transmission rod 200, preferably a flexible coupling.

[0042] In use, the transmission rod 200 is connected to the riveting motor 700 via a flexible coupling 710. The riveting motor 700 drives the transmission rod 200 to rotate, which in turn rotates the rivet rod 400, compressing the telescopic component 210 and completing the riveting action. An input gear 810 is mounted on the rivet motor 800, and an output gear 830 is mounted on the planetary screw 300, connected via a transmission gear 820. The rivet motor 800 drives the gear to rotate, causing the planetary screw 300 to move up and down, completing the riveting action of the rivet nut. Simultaneously, the planetary screw drives the displacement sensor 310 to move, verifying the riveting distance. When replacing the rivet rod 500, manually press the plunger 630, rotate and remove the limit sleeve 620, manually push the thrust sleeve 640, compress the replacement component 650, rotate and remove the rivet rod 500. After replacement, the replacement component 650 automatically resets after compression.

[0043] This application, through the configuration of a housing 100, transmission rod 200, planetary screw 300, rivet rod 400, and rivet rod 500, enables riveting and rivet insertion. A floating ring 600 is incorporated to generate a floating amount during operation, ensuring uniform force distribution. A displacement sensor 310 is installed on the planetary screw 300 to verify and accurately determine the rivet distance. A plug 630 is provided to secure the limiting sleeve 620 to the floating sleeve 600. A thrust sleeve 640 and a rivet replacement part 650 are also included for easier replacement of the rivet rod 500. Through these configurations, this application achieves a novel overall structure, convenient maintenance, and precise rivet distance control via a displacement sensor. The gear structure transmits high torque, resulting in a compact design that promotes miniaturization and reliability. The front-end floating mechanism ensures uniform force distribution on the floating ring, stable centering performance, and significantly reduced production failure rates. This design solves the technical problems of traditional rivet guns with rigid end connections lacking floating amount, which can easily lead to material jamming and difficulty in finding holes during actual production.
