[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0031] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a pull-off rivet, comprising a connecting rod 7, a sliding sleeve 1 is slidably connected to the outer wall of the connecting rod 7, a sliding cylinder 6 is slidably connected to the outer wall of the connecting rod 7, a hoop 4 is fixedly connected to the outer wall of the hoop 4, a clamping ring 5 is fixedly connected to the outer wall of the hoop 4, a clamping head 3 is fixedly connected to the outer wall of the clamping head 3, the outer wall of the connecting rod 7 is slidably connected to the outer wall of the connecting rod 7, and a clamping assembly is provided on the outer wall of the connecting rod 7;

[0032] Specifically, first, the chuck 3 is connected to a manual or automatic tool as a driving component to apply force to push the slide 6 to move along the inner wall of the sleeve 1. The slide 6 is a hollow cylindrical component, and may have one or more raised parts inside, which is used to drive the hoop 4. As the slide 6 moves, the hoop 4 is compressed and driven, and gradually expands to adapt to the inner diameter of the sleeve 1. The hoop 4 is a closed annular component, which is compressed or expanded by the action of the slide 6. Once the hoop 4 is fully expanded and clamped into the inner side of the sleeve 1, it retracts through its own elasticity and is tightly fixed to the inner wall of the sleeve 1. The clamping ring 5 on the hoop 4 is designed to increase the friction with the inner wall of the sleeve 1, thereby preventing the hoop 4 from being fixed on the fixed object. This device can provide a strong fixing force to ensure that the object will not fall off from the other side when it is fixed. It is faster than the traditional rivet fixing method because there is no need to operate from the other side. In addition, due to the elasticity of the hoop 4, it can maintain the fixing force in an environment of vibration or temperature change. The working principle and advantages of this fixing device make it an ideal choice for occasions that require a fast, reliable and strong fixing solution. When using this fixing device, it is necessary to ensure that the material strength of the sliding sleeve 1 and the hoop 4 is sufficient to withstand the expected load. In order to achieve the best fixing effect, the inner wall of the sliding sleeve 1 and the surface of the hoop 4 may need to be specially treated to increase the friction between them.

[0033] Reference Figure 1 - Figure 3 The clamping assembly includes a slider 8, the outer wall of the slider 8 is fixedly connected to the outer wall of the connecting rod 7; the outer wall of the slide tube 6 is arranged on the inner wall of the sliding sleeve 1; the outer wall of the slider 8 is fixedly connected to the support block 9; the outer wall of the support block 9 is arranged on the inner wall of the sliding sleeve 1; the outer wall of the slider 8 is arranged on the inner wall of the sliding sleeve 1; the outer wall of the sliding sleeve 1 is fixedly connected to the support plate 2; the inner wall of the support plate 2 is slidably connected to the outer wall of the connecting rod 7;

[0034] Specifically, first, the rivet is inserted into the pre-drilled hole between the two objects to be fixed. Next, the rivet gun is operated to pull the connecting rod 7. The connecting rod 7 pulls the slider 8 and the support block 9 to move in the direction of the sleeve 1 through mechanical linkage. At the same time, the rivet gun also pushes the clamping head 3 to move in the direction of the sleeve 1. The slider 8 drives the support block 9 during the movement, so that it is stuck in the sleeve 1. The function of the support block 9 is to support the sleeve 1, thereby applying pressure to one of the objects to achieve fixation. The main advantages of this fixing method are fast speed, simple operation, and can be completed without relying on external power supply or complex tools. The pressure applied to the object by the sleeve 1 supported by the support block 9 ensures the stability of the fixation. It is suitable for occasions where the fixing operation needs to be completed quickly on site. To ensure the fixing effect, the materials and sizes of components such as the sleeve 1, slider 8 and support block 9 need to be selected according to the load requirements in actual applications.

[0035] Working principle: when a pull-off rivet is needed, the rivet is inserted between the two objects to be fixed, the connecting rod 7 is pulled by the rivet gun, the slider 8 and the support block 9 are pulled toward the direction of the sleeve 1 by the connecting rod 7, and the clamping head 3 is pushed toward the direction of the sleeve 1 by the rivet gun, so that the support block 9 is clamped inside the sleeve 1 by the slider 8, and one of the objects is fixed by the sleeve 1 supported by the support block 9, so as to achieve the effect of quickly fixing the object, and then the slide 6 and the hoop 4 are clamped on the other side of the sleeve 1 by the clamping head 3, and the hoop 4 is driven by the slide 6 to clamp into the inner side of the sleeve 1, and the hoop 4 is clamped on the inner wall of the sleeve 1 by the clamping ring 5 on the hoop 4, so as to prevent the object from falling off from the other side when fixed, so as to achieve the effect of stably fixing the object by rivets.
