[0020] 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.

[0021] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention. Example

[0022] See also Figure 1-Figure 4 As shown, this embodiment provides a quick-change rivet rod mechanism for a rivet gun, including a mounting ring 1, a surface of the mounting ring 1 is provided with a limiting tube 3 for installation through a connecting ring 2, the interior of the connecting ring 2 is provided with a rebound component 4 for automatic pop-up, the interior of the limiting tube 3 is clamped with a quick-change structure 5, and a rivet rod 6 is fixedly installed at one end of the quick-change structure 5.

[0023] The rivet rod 6 is clamped in the interior of the limiting tube 3 through the quick-change structure 5. After clamping, when the personnel need to replace the rivet rod 6, the positioning cover 7 is opened, and the limiting rod 505 slidably connected inside the positioning cover 7 is pulled out. After being pulled out, the rebound component 4 will pop out the rivet rod 6. After popping out, the personnel can replace the rivet rod 6, thereby achieving the effect of quickly replacing the rivet rod 6.

[0024] like Figures 1 to 4As shown, the quick-change structure 5 includes a clamping tube 501 inserted into the limiting tube 3, the internal thread of the clamping tube 501 is connected to the mounting rod 502, one end of the mounting rod 502 is provided with a first spring 503, one end of the first spring 503 is fixedly installed with an extrusion block 504, the surface of the extrusion block 504 is slidably connected to the limiting rod 505, the position of the extrusion block 504 close to the limiting rod 505 is set to a cone, both sides of the surface of the clamping tube 501 are provided with positioning grooves, the internal thread of the positioning groove is connected to the positioning cover 7, the surfaces of the mounting rod 502 and the clamping tube 501 are provided with through grooves, the internal thread of the through groove passes through the limiting bolt 8, the limiting bolt 8 is inserted between the mounting rod 502 and the clamping tube 5 01, so as to fix the positions of the mounting rod 502 and the clamping tube 501. At the same time, a mounting groove is opened inside the positioning cover 7, and the size of the mounting groove is adapted to the size of the limiting rod 505. The limiting rod 505 is slidably set in the mounting groove. When the mounting rod 502 rotates inside the clamping tube 501 and moves toward the inside of the clamping tube 501, the mounting rod 502 pushes the extrusion block 504 toward the direction close to the mounting ring 1 by pushing the first spring 503. At this time, the conical surface of the extrusion block 504 squeezes one end of the limiting rod 505, so that the two limiting rods 505 move in the direction away from the extrusion block 504, so that the two limiting rods 505 slide in the mounting groove.

[0025] When the rivet rod 6 is in use, the personnel inserts the clamping tube 501 into the interior of the limiting tube 3, and then the personnel rotates the rivet rod 6. When the rivet rod 6 is rotated, the installation rod 502 is driven to move forward. When the installation rod 502 moves forward, the extrusion block 504 is driven to move forward through the first spring 503, and the extrusion block 504 squeezes the limiting rod 505 sliding inside the clamping tube 501, and the limiting rod 505 slides to the interior of the positioning cover 7. The limiting rod 505 fixes the rivet rod 6. After fixation, the limiting bolt 8 is used to fix the other end of the clamping tube 501. When the rivet rod 6 needs to be replaced after fixation, the positioning cover 7 is unscrewed, and the limiting rod 505 is taken out after unscrewing. The rebound component 4 will pop out the clamping tube 501 for replacement, thereby achieving the effect of quickly replacing the rivet rod 6.

[0026] like Figures 1 to 4 As shown, the rebound assembly 4 includes a telescopic rod 401 arranged inside the connecting ring 2, a second spring 402 is sleeved on the surface of the telescopic rod 401, and one end of the telescopic rod 401 is overlapped on one end of the clamping tube 501.

[0027] During use, after the personnel release the fixing of the card tube 501, since the telescopic rod 401 and the second spring 402 are always compressed, the telescopic rod 401 and the second spring 402 will automatically rebound when they are not squeezed, and the card tube 501 will be ejected, thereby cooperating with the quick-change structure 5 to replace the rivet rod 6.

[0028] The working principle and use process of the utility model are as follows: the installation ring 1 and the rivet gun are connected. After the connection, the personnel insert the clamping tube 501 into the interior of the limiting tube 3, and then the personnel rotates the rivet rod 6. When the rivet rod 6 rotates, it will drive the installation rod 502 to move forward. When the installation rod 502 moves forward, the extrusion block 504 will be driven to move forward through the first spring 503, and the extrusion block 504 will squeeze the limiting rod 505 sliding inside the clamping tube 501, and the limiting rod 505 will slide to the interior of the positioning cover 7, and the limiting rod 505 fixes the rivet rod 6. After fixing, use the limiting bolt 8 to fix the other end of the clamping tube 501. When the rivet rod 6 needs to be replaced after fixing, the positioning cover 7 is twisted open, and the limiting rod 505 is taken out after twisting open, and the rebound component 4 will pop out the clamping tube 501 for replacement.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
