Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0016] This application designs a ring pressing tool for operation in confined spaces, as shown in the attached document. Figure 1-3 As shown, it includes a handle 1, an upper pressure block 2, a slide groove 3, a rotating block 6, a lower pressure block 8, a slider 10, an elastic rotating shaft 11, and a storage groove 12; The upper pressure block 2 is fixedly connected to the bottom of the handle 1, and the slide groove 3 is opened on both sides of the upper pressure block 2. The slide groove 3 is semi-circular. There are two sliders 10. The sliders 10 are movably connected to the slide groove 3. The elastic rotating shaft 11 is fixedly connected to the sliders 10. The elastic rotating shaft 11 includes a torsion spring, which can automatically rebound to reset the rotating block 6. The rotating block 6 is rotatably connected to the elastic rotating shaft 11. The sliders 10 are driven by a motor. The rotating block 6 and the upper pressure block 2 have the same arc and are located on the same circumference. Therefore, when rotating to the lower position, it is still located below the upper pressure block 2, thus avoiding occupying extra space. The storage groove 12 is located inside the rotating block 6. The lower pressing block 8 is movably connected to the storage groove 12. The lower pressing block 8 is a quarter arc shape. The two lower pressing blocks 8 and the upper pressing block 2 work together to form a complete circumference, which is used to crimp the pipe interface.

[0017] Furthermore, a screw 7 is threadedly connected to the side of the rotating block 6, and the screw 7 passes through the inside of the storage groove 12 and is rotatably connected to the lower pressure block 8; The storage slot 12 is fixedly connected to the internal limit rod 15. The outer wall of the lower pressure block 8 is provided with a through hole 13. The through hole 13 is fixedly connected to the internal limit strip 14. The through hole 13 is sleeved on the outside of the limit rod 15. The side of the limit rod 15 is provided with a slot that is movably connected to the limit strip 14. A spring 16 is provided on the outside of the limiting rod 15. The two ends of the spring 16 are fixedly connected to the rotating block 6 and the lower pressing block 8, respectively. The spring 16 is used to provide support force and enhance the fixing effect on the lower pressing block 8.

[0018] Furthermore, a limiting plate 4 is fixedly connected to the outer wall of the upper pressure block 2. The limiting plate 4 has the same curvature as the rotating block 6. The ends of both the limiting plate 4 and the rotating block 6 are rounded. The limiting effect of the limiting plate 4 drives the rotating block 6 to rotate and clamp.

[0019] Furthermore, the inner ring of the upper pressure block 2 is fixedly connected with pressure strip 5, and the inner ring of the lower pressure block 8 is fixedly connected with pressure strip 9. Pressure strip 5 and pressure strip 9 have the same curvature. Pressure strip 5 and pressure strip 9 are used to directly contact the pipe and crimp the pipe.

[0020] Working principle: Place the upper pressure block 2 above the pipe to be crimped, then start the sliders 10 on both sides to move along the slide groove 3. When the rotating block 6 passes the limiting plate 4, the limiting plate 4 presses down the rotating block 6, so that the rotating block 6 and the upper pressure block 2 are on the same circumference, thereby unfolding the rotating block 6. Then, the lower pressure block 8 is pushed out by the screw 7, so that the second pressure strip 9 and the first pressure strip 5 are on the same circumference. The pipe is surrounded and squeezed by the first pressure strip 5 and the second pressure strip 9, thereby completing the crimping of the pipe.

[0021] The above embodiments are only some embodiments of this utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the protection scope of this utility model.
