It is suitable for use in the fields of automobile manufacturing, construction industry, furniture manufacturing, machinery manufacturing, etc.

[0003] A rivet gun with publication number CN219378858U is designed with mechanisms on two parallel lines, wherein the straight line where the power assembly is located is responsible for providing power, the straight line where the slide rail slider and the rivet rod assembly are located is responsible for contacting the rivet, and a discharge channel is designed in the rivet rod assembly, through which broken rivets can be sucked out, thereby achieving the technical purpose of automatic integration of punching and discharge. However, the equipment size at the front end of this rivet gun is fixed, and it is difficult to meet the connection requirements of rivet nuts of different sizes. It is necessary to provide a rivet nut fastening mold that can be easily replaced to facilitate the fastening operation of rivet nuts of different sizes. At the same time, since the rivet gun is driven by pneumatics, the simple button operation makes the rivet gun easy to be accidentally touched, and safety cannot be guaranteed.

[0004] In view of the above problems, a rivet gun with a transformable rivet nut fastening die is proposed. Utility Model Content

[0005] The utility model aims to provide a rivet gun with a transformable rivet nut fastening die, which solves the problem that the size of the front end die of the existing rivet gun in the background technology is fixed, which makes it difficult to meet the connection requirements of rivet nuts of different sizes; at the same time, since the rivet gun is driven by pneumatics, the simple button operation makes the rivet gun easy to be accidentally touched and the safety cannot be guaranteed.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rivet gun with a transformable rivet nut fastening mold, comprising a rivet gun fixing mechanism, an adjustable safety adjustment mechanism is inserted into the upper end of the rivet gun fixing mechanism, a replaceable front mold conversion mechanism is snap-connected to one side of the rivet gun fixing mechanism, the rivet gun fixing mechanism comprises a gun housing, a slot is opened at the upper end of the gun housing, the safety adjustment mechanism comprises a fixed block and a guide block fixedly arranged on both sides of the upper end of the slot, an L-shaped plug block arranged between the fixed block and the guide block, an adjustment rod threadedly connected to the L-shaped plug block and the guide block, the front mold conversion mechanism comprises a built-in plug arranged on one side of the gun housing, a sealing block inserted into the built-in plug, and a connecting mold threadedly connected to the built-in plug.

[0007] Preferably, the fixing mechanism of the rivet gun includes a handheld component fixedly arranged at the lower end of the gun housing, and the handheld component includes a connecting rod screwed to the gun housing, and a U-shaped gripping rod fixedly arranged on one side of the connecting rod.

[0008] Preferably, an internal tube is provided inside the gun housing, a front bayonet is provided on one side of the gun housing corresponding to the front mold conversion mechanism, and a slot is provided on the internal tube.

[0009] Preferably, two groups of guide rods are fixedly provided on one side of the L-shaped plug block, and the two groups of guide rods are correspondingly inserted into the guide block.

[0015] 1. The utility model provides a rivet gun with a transformable rivet nut fastening mold. Through the setting of a safety adjustment mechanism, a slot set on the gun housing is blocked by an L-shaped plug. The L-shaped plug slides between a fixed block and a guide block. The rotation of an adjustment rod drives the L-shaped plug to rise and fall to realize the opening and closing control of the gun housing. The setting of this structure requires that when the rivet gun is used, the L-shaped plug needs to be rotated out and raised. Under normal storage conditions, the L-shaped plug is lowered to block the pneumatic control port of the gun housing to ensure safety. This solves the problem that the existing rivet gun is easily touched by mistake due to the use of pneumatic drive and the simple button operation makes the rivet gun unable to ensure safety.

[0016] 2. The utility model provides a rivet gun with a transformable rivet nut fastening mold. Through the setting of the front mold conversion mechanism, the built-in plug rod is engaged between the sealing block and the gun housing. This structure makes the connecting mold replaceable.

[0026] Specifically, the slot 123 provided on the gun housing 12 is blocked by the L-shaped plug 23, the fixed block 21 and the guide block 22 are connected and fixed to the built-in tube 121, and the L-shaped plug 23 slides between the fixed block 21 and the guide block 22. The rotation of the adjusting rod 24 drives the L-shaped plug 23 to rise and fall to realize the opening and closing control of the gun housing 12. The setting of this structure makes it necessary for the L-shaped plug 23 to be rotated out and raised when the rivet gun is in use. Under normal storage conditions, the L-shaped plug 23 is lowered to block the pneumatic control port of the gun housing 12 to ensure safety. The built-in plug rod 31 is engaged between the sealing block 32 and the gun housing 12, and the sealing block 32 and the gun housing 12 are connected to each other. The connecting mold 34 is rotated on the built-in plug rod 31 for fixing. This structure makes the connecting mold 34 replaceable, and only one side needs to be connected to the built-in plug rod 31. The built-in plug rod 31 is also detachable, and the internal situation of the gun housing 12 can be checked, and the operation of disassembling and replacing the connecting mold 34 is relatively simple.

[0027] The utility model is further described below in conjunction with embodiments.

The through rod 242 is movably set in the L-shaped plug block 23. The through rod 242 is sleeved in the L-shaped plug block 23 and can rotate in the L-shaped plug block 23. The threaded rod 241 is threadedly connected to the guide block 22. The rotation of the threaded rod 241 drives the through rod 242 to rise and fall, thereby driving the L-shaped plug block 23 sleeved on the outside of the through rod 242 to rise and fall, thereby realizing the blocking control of the slot 123.

[0033] Embodiment 2:

[0034] Combination Figure 4 and Figure 5 The front mold conversion mechanism 3 also includes screws 33 connected to the gun housing 12 and the sealing block 32. There are four groups of screws 33. The screws 33 realize threaded fixation of the gun housing 12 and the sealing block 32, and can fix the built-in insertion rod 31 between the gun housing 12 and the sealing block 32.

[0035] The built-in insertion rod 31 includes a locking block 311 set on one side of the locking sealing block 32, and one end of the built-in insertion rod 31 is set as a side threaded edge 312. The locking block 311 is matched with the opening shape of one side of the sealing block 32. The setting of the side threaded edge 312 facilitates rotation and replacement connection with the connecting mold 34.

[0036] The connecting mold 34 includes a nut frame 342 set on the rotatable connecting side thread edge 312. A rivet pin socket 341 is opened at one end of the connecting mold 34.
