[0017] 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 technical personnel in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 - Figure 5 , the utility model provides a technical solution:

[0019] A short-tail rivet comprises a flat nail body 1, one side of the top of the flat nail body 1 is fixedly connected with an extrusion block 2, the middle part of the top of the flat nail body 1 is fixedly connected with a tightening nail body 3, the outer surface of the tightening nail body 3 is fixedly connected with a transverse protrusion 4, and the side of the tightening nail body 3 away from the flat nail body 1 is fixedly connected with a bare rod nail body 5. In the process of using the equipment, a hole matching the diameter of the rivet is pre-drilled on the wooden board to ensure that the hole is clean and free of debris. The rivet cap 8 is placed on the tightening nail body 3 to ensure that the transverse groove 10 of the rivet cap 8 is aligned with the transverse protrusion 4 on the tightening nail body 3. At this time, the rivet is inserted and one end of the flat nail body 1 of the rivet is inserted into the pre-drilled hole in the wooden board to ensure that the rivet completely passes through the board. The design of the flat nail body 1 increases the contact area with the board and improves the stability of the connection. A rivet gun or special tools is used during the riveting process.

[0020] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a short and thin annular groove nail body 6 is fixedly connected to the side of the bare rod nail body 5 away from the tightening nail body 3, and an engaging block 7 is fixedly connected to the outer surface of the short and thin annular groove nail body 6. A rivet cap 8 is movably connected to the top of the flat nail body 1. The engaging block 7 at the other end of the flat nail body 1 is connected to the pull rod of the rivet gun. The rivet gun applies an outward pulling force to move the rivet cap 8 upward along the rivet. In this process, the transverse groove 10 of the rivet cap 8 fits with the transverse protrusion 4 of the tightening nail body 3 to form a tight connection. As the pulling force increases, the connection becomes more secure. The extrusion block 2 of the rivet is a columnar object with a thick bottom and a thin head made of easily deformable material. When the rivet cap 8 is deformed by the pulling force, the extrusion block 2 will be driven to deform, thereby increasing the contact area between the rivet and the plate and improving stability.

[0021] In this embodiment, Figure 4 and Figure 5 As shown, the rivet cap 8 is movably connected with the tightening nail body 3, and the inner cavity of the rivet cap 8 is provided with an extrusion chamber 9. The inner wall of the extrusion chamber 9 is fixedly connected with a transverse groove 10, and the transverse groove 10 is meshed with the transverse protrusion 4. After riveting is completed, when the rivet cap 8 moves to a certain position, the rivet gun will release a sudden force to further tighten the rivet cap 8 on the tightening nail body 3. This sudden force presses the rivet bare rod nail body 5 partly into the plate to form a solid riveting point. The short and thin ring groove nail body 6 and the engaging block 7 at the tail of the rivet ensure that the riveter can be firmly engaged during the riveting process to prevent slipping and damage.

[0022] The use method and advantages of the utility model: When the short-tail rivet is used, the working process is as follows:

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in the process of using the equipment, a hole matching the diameter of the rivet is pre-drilled on the wooden board to ensure that the hole is clean and free of debris, the rivet cap 8 is placed on the tightening nail body 3, and the transverse groove 10 of the rivet cap 8 is aligned with the transverse protrusion 4 on the tightening nail body 3. At this time, the rivet is inserted, and one end of the flat nail body 1 of the rivet is inserted into the pre-drilled hole in the wooden board to ensure that the rivet completely passes through the board. The design of the flat nail body 1 increases the contact area with the board and improves the stability of the connection. During the riveting process, a rivet gun or special tool is used to connect the engaging block 7 at the other end of the flat nail body 1 to the pull rod of the rivet gun, and an outward pulling force is applied through the rivet gun to move the rivet cap 8 upward along the rivet. In this process, the transverse groove 10 of the rivet cap 8 is aligned with the transverse protrusion 4 on the tightening nail body 3. The lateral protrusions 4 of the tightening nail body 3 fit together to form a tight connection. As the pulling force increases, the connection becomes more secure. The extrusion block 2 of the rivet is a columnar object with a thick bottom and a thin head made of easily deformable material. When the rivet cap 8 is deformed by the pulling force, the extrusion block 2 will be deformed, thereby increasing the contact area between the rivet and the plate and improving stability. After the riveting is completed, when the rivet cap 8 moves to a certain position, the rivet gun will release a sudden force to further tighten the rivet cap 8 on the tightening nail body 3. This sudden force presses part of the rivet bare rod nail body 5 into the plate to form a solid riveting point. The short and thin ring groove nail body 6 and the engagement block 7 design at the tail of the rivet ensure that the riveter can be firmly engaged during the riveting process to prevent slippage and damage.

[0024] The above shows and describes the basic principle, main features and advantages of the utility model.
