[0019] The following further describes this utility model in conjunction with the embodiments. The following only describes a part of the embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of this utility model.

[0020] Figure 1:The riveting pliers for narrow construction spaces mainly consist of a short pressing piece 1, a long pressing piece 2, a force - applying handle 3, a rotating shaft screw 4, a rolling ring 5, a spring 6, a threaded riveting head 7, a upsetting block 8, etc. This device mainly completes riveting by the interaction between the short pressing piece 1 and the long pressing piece 2; by adjusting the threaded length of the riveting head 7, it can adapt to rivets of various lengths.

[0021] As shown in the Figure 1 , 2 figure, a manual riveting tool for narrow spaces is provided, which mainly includes seven parts: a short pressing piece 1, a long pressing piece 2, a force - applying handle 3, a rotating shaft screw 4, a rolling ring 5, a spring 6, a threaded riveting head 7, and a upsetting block 8. Among them, loosen the force - applying handle 3, let the short pressing piece 1 and the long pressing piece 2 open freely to the maximum, align the opening with the rivet to be riveted, and then press down the force - applying handle 3 forcefully so that the short pressing piece 1 and the long pressing piece 2 apply pressure to the rivet head and the rivet rod to complete riveting.

[0022] The following further explains the utility model of the riveting pliers for non - open areas of the present utility model with reference to the attached drawings: As shown in the figure, a riveting pliers tool for narrow construction spaces is provided, which mainly includes seven parts: a short pressing piece 1, a long pressing piece 2, a force - applying handle 3, a rotating shaft screw 4, a rolling ring 5, a spring 6, a threaded riveting head 7, and a upsetting block 8. During operation, first loosen the force - applying handle 3. Under the action of the pulling force of the spring 6 and through the rotation of the rotating shaft screw 4, the opening between the short pressing piece 1 and the long pressing piece 2 is widened. Then, by adjusting the protruding length of the threaded riveting head 7, the gap between the two threaded riveting heads 7 is controlled to match the length of the rivet. Align the upsetting block 8 with the rivet cap and place it in the central position, and then place the rivet cap on the other threaded riveting head 7. By applying a downward pressure to the force - applying handle 3, and through the lever action between the force - applying handle 3 and the rotating shaft screw 4, after reducing the friction force through the rolling ring 5, a force is applied to the short pressing piece 1. Then, through the lever action between the short pressing piece 1 and the rotating shaft screw 4, the short pressing piece 1 moves downward relative to the long pressing piece 2 to squeeze. Finally, through the extrusion force acting between the upsetting block 8 and the threaded riveting head 7, a rivet upset head is formed and the rivet riveting is completed.

[0023] The riveting pliers for narrow construction spaces have a compact and simple structure. It can be adjusted to adapt to rivets of different lengths, which not only solves the problem of the mismatch between the tool and the rivet length, but also can replace different riveting heads to adapt to different types of rivets.
