[0022] like Figure 1-Figure 5 As shown, a foldable structure proposed in this embodiment includes a front handle 1, a connecting frame 2, a rear handle 3 and a limiting component.

[0023] The connecting frame 2 is fixedly connected to the front handle 1 through a first rivet 8, and is rotatably connected to the rear handle 3 through a second rivet 9. The first rivet 8 can be connected to multiple. A limit rivet 7 is provided on the rear handle 3, and a handle sleeve 4 is mounted on the rear handle 3 to improve the comfort of the user when holding it. The rear handle 3 is a U-shaped structure. After the foldable structure is unfolded, the limit assembly limits the rear handle 3 from rotating outward relative to the connecting frame 2. When the rear handle 3 of the U-shaped structure rotates inward, it automatically drives the connecting frame 2 and the front handle 1 to rotate inward.

[0024] The connecting frame 2 includes two limiting plates and a plurality of connecting plates stacked and connected between the two limiting plates, and has a slideway 201 located on the limiting plates.

[0025] The limiting assembly includes a push button 5 and an elastic member. The elastic member is tensioned and connected between the push button 5 and the connecting frame 2. The elastic member can be a spring 6. The push button 5 has a groove for the spring 6 to extend into, and the spring 6 is not easy to fall off. The push button 5 is slidably arranged on the slide 201. The top and bottom ends of the push button 5 both have a slide portion 52 that can slide on the slide 201, that is, both sides have a slide portion 52 that slides on the slides 201 of the two limiting plates respectively, and the slide 201 also limits the range of movement of the push button 5. The side of the push button 5 has an anti-slip groove to facilitate the user to push the push button 5, and the push button 5 moves in the inclined direction. The push button 5 has an outwardly protruding blocking platform 51. When the blocking platform 51 is blocked at the limiting rivet 7, it can limit the rotation of the rear handle 3 relative to the connecting frame 2. As Figure 6 As shown, when the foldable structure is connected to a riveting tool, the connection is made through the front handle 1, and the connection position is the same as the connection position of the handle in the existing riveting tool.

[0026] After folding, the present embodiment has a smaller size, saves packaging costs, and is more convenient to carry and transport. After unfolding, the handle sleeve 4 is held for use, the entire handle is long, and the operation is labor-saving. The spring 6 can push the push button 5 outward, and the push button 5 is stably blocked at the limit rivet 7 to prevent the rear handle 3 from rotating relative to the connecting frame 2. When folding, the push button 5 is pushed inward to compress the spring 6, release the limit on the limit rivet 7, and rotate the rear handle 3 outward with the second rivet 9 as the center axis and fold it. After folding, the overall length becomes shorter, which is convenient for storage and carrying.

[0027] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
