[0023] The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model, and obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of protection of the utility model.

[0024] In this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0025] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0026] like Figures 1-6 As shown, an embodiment of the present application provides a tool for riveting nuts. In some embodiments, the tool 10 includes a mounting rod 11, a mounting groove 12 is provided on one side of the mounting rod 11, a groove wall 13 is provided on the inner periphery of the mounting groove 12, and the groove wall 13 is polygonal. The nut 20 is placed in the mounting groove 12, and the outer wall of the nut 20 is engaged with the groove wall 13 of the mounting groove 12; a bottom hole 14 is provided on one side of the mounting groove 12, and the mounting groove 12 is coaxial with the bottom hole 14.

[0027] In some embodiments, the sum of the depths of the bottom hole 14 and the mounting groove 12 is equal to the thickness of the mounting rod 11. Figure 4 For example, the bottom hole 14 and the mounting groove 12 are Figure 4 The sum of the depths in the vertical direction is equal to the depth of the mounting rod 11 in Figure 4 Through this design, the mounting groove 12 and the bottom hole 14 run through the entire mounting rod 11, making it easy for the head of the rivet gun 40 to extend into the mounting groove 12 and the bottom hole 14 to rivet the nut 20.

[0028] Optionally, the groove wall 13 is octagonal, the outer wall of the nut 20 is also octagonal, and the octagonal outer wall of the nut 20 is embedded in the octagonal groove wall 13 of the installation groove 12.

[0029] In this embodiment, the groove wall 13 of the mounting groove 12 is polygonal and is adapted to the outer wall of the nut 20, so that the polygonal outer wall of the nut 20 can be embedded in the polygonal groove wall 13 of the mounting groove 12. When the rivet gun 40 rivets the nut 20, since the polygonal outer wall of the nut 20 is embedded in the polygonal groove wall 13 of the mounting groove 12, the two polygons are embedded, which can effectively prevent the nut 20 from rotating with the gun head of the rivet gun 40 during riveting, so that the mounting groove 12 can fix the nut 20 and prevent the nut 20 from rotating, thereby ensuring the effective riveting operation.

[0030] Optionally, the mounting rod 11 is a rectangular parallelepiped structure, and the mounting groove 12 is provided at a middle position on one side of the mounting rod 11 .

[0031] In some embodiments, the cross section of the bottom hole 14 is smaller than the cross section of the mounting slot 12. With this design, the mounting slot 12 can support the nut 20 and prevent the nut 20 from falling out of the mounting slot 12.

[0032] In some embodiments, the cross section of the bottom hole 14 is circular.

[0033] In this embodiment, the bottom hole 14 is configured as a circular hole, which can be adapted to the gun head of the rivet gun 40 , making it easy for the gun head of the rivet gun 40 to extend into the bottom hole 14 , thereby facilitating riveting operations.

[0034] In some embodiments, the cross section of the mounting rod 11 is smaller than the cross section of the inner wall of the pipe 30. With this design, the mounting rod 11 can extend into the inner cavity of the pipe 30, thereby moving the nut 20 to the rivet hole 31 of the pipe 30.

[0035] like Figures 5-7 As shown, during use, the nut 20 is placed in the mounting groove 12 of the mounting rod 11, with the polygonal outer wall of the nut 20 embedded in the polygonal groove wall 13 of the mounting groove 12. The mounting rod 11 is inserted into the inner cavity of the pipe 30, and the mounting rod 11 is moved so that the nut 20 fixed in the mounting rod 11 moves to the rivet hole 31 opened in the pipe 30. The gun head of the rivet gun 40 is passed through the upper end of the rivet hole 31, and the gun head of the rivet gun 40 is rotated and lowered to extend into the inner hole of the nut 20 in the inner cavity of the pipe 30, and engages with the inner thread of the nut 20. The mounting rod 11 is lowered, and the gun head of the rivet gun 40 is rotated and raised to install the nut 20 on the inner wall of the rivet hole 31 of the pipe 30 by means of pull rivets. Repeat the above steps until all rivet holes 31 in the pipe 30 are installed with nuts 20 by means of pull rivets.

[0036] In summary, the nut pull rivet of the utility model provides a tool, the tool simple structure, convenient to use, fast operation, can install the nut in the pipe inner wall in the way of pull rivet, be applicable to install the nut in the special installation structure such as pipe material etc.
