[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a folding handle includes: a base shaft 20, which is cylindrical, as is existing technology, and therefore will not be described in detail here.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a folding structure is installed on the wall of the base shaft 20 to control the rotation of the base shaft 20. The folding structure includes: a fixed plate 21, a fixed shaft 22, an adjusting plate 24, an adjusting groove 25, a rib 27, and a sliding rod 30. The fixed plate 21 is symmetrically fixedly connected to the top of the base shaft 20, the fixed shaft 22 is fixedly connected between the symmetrical fixed plates 21, the adjusting plate 24 is slidably connected to the top of the base shaft 20, the adjusting groove 25 is symmetrically opened on the top of the adjusting plate 24, the rib 27 is symmetrically fixedly connected to the top of the adjusting plate 24, and the sliding rod 30 is slidably connected to the wall of the symmetrical rib 27. The sliding rod 30 and the rib 27 can be folded above the base shaft 20.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the fixed plate 21 is a rectangular block, the fixed shaft 22 is cylindrical, and the adjusting plate 24 is a rectangular plate. The symmetrical fixed plates 21 can pass through the symmetrical adjusting grooves 25. The wall surface of each bone rod 27 also has the same adjusting groove 25. The fixed plates 21 can slide simultaneously within the adjusting grooves 25 on the wall surface of the bone rod 27. The bone rod 27 is a rectangular rod, and its length is consistent with the top of the adjusting plate 24. The sliding rod 30 is a U-shaped frame. The cavity of the sliding rod 30 can fit against the side wall surface of the symmetrical bone rod 27. The cavity of the sliding rod 30 can adapt to the movement of the symmetrical bone rod 27. The folding structure also includes bolts 23, locking grooves 26, sliding grooves 28, connecting plates 29, and connecting columns 31. Bolts 23 are threaded to the top of the fixed shaft 22. The locking groove 26 is opened through the top of the adjusting plate 24. The sliding groove 28 is also open through the top of the adjusting plate 24. 8 is opened through the side wall of the bone rod 27. The connecting plate 29 is fixedly connected to the end of the symmetrical bone rod 27. The connecting column 31 is symmetrically fixedly connected to the opening of the slide rod 30. The sliding groove 28 can communicate with the adjustment groove 25 on the wall of the bone rod 27. The sliding groove 28 on the inner side of the symmetrical bone rod 27 can be adapted to the sliding of the fixed plate 21. The sliding groove 28 on the outer side of the symmetrical bone rod 27 can be adapted to the sliding of the connecting column 31. The connecting column 31 is cylindrical. The bolt 23 can penetrate from the top of the fixed shaft 22. The locking groove 26 can be adapted to the size of the bolt 23. The bottom front and rear ends and the middle section of the adjustment plate 24 are respectively opened with the same locking groove 26. The connecting plate 29 is a rectangular plate with a circular groove on the top. A cylindrical magnet is fixedly connected in the circular groove of the connecting plate 29. The magnet on the wall of the connecting plate 29 can attract the bottom of the slide rod 30.

[0032] In practical use, when it is necessary to control the rotation of the base shaft 20, slide the slide rod 30 in a direction where there is room for rotation. As the slide rod 30 slides, it will drive the connecting column 31 to slide synchronously along the slide groove 28. As the slide rod 30 gradually slides, the end of the bone rod 27 will align with the opening of the slide rod 30. At this time, moving the slide rod 30 in the desired direction will cause the adjusting plate 24 and the fixed plate 21 to contact through the bone rod 27, and then drive the base shaft 20 to rotate. After the slide rod 30 is used, slide the slide rod 30 back in the original direction. When it slides to the original position, the magnet on the wall of the connecting plate 29 will attract the bottom of the slide rod 30, thereby fixing the position of the slide rod 30. When adjustment is needed, the slide rod 30 can be moved back to its original position. When the plate 24 is positioned at the top of the base shaft 20 to accommodate the space, the bolt 23 is tightened. When the bolt 23 is tightened upwards, it will separate upwards from the corresponding locking groove 26. At this time, the adjusting plate 24 can slide along the top of the base shaft 20. As the adjusting plate 24 is unlocked, the slide bar 30 at the top of the adjusting plate 24 will also move synchronously with the movement of the adjusting plate 24. The adjusting plate 24 can slide from the bottom left side to the bottom right side of the base shaft 20. When it is necessary to fix the position of the adjusting plate 24, the bolt 23 is turned downwards again to drive the bolt 23 to be inserted into the corresponding locking groove 26 to fix the position of the adjusting plate 24.

[0033] In summary, by setting a folding structure, the base shaft 20 can be controlled to rotate even in confined spaces by unlocking and locking the adjustment plate 24 to slide on top of the base shaft 20. This solution enables the base shaft 20 to rotate even in confined spaces.

[0034] like Figure 2 and Figure 5 As shown, a capsule-shaped groove is opened through the front arc surface of the base shaft 20. The size of the capsule-shaped groove on the wall of the base shaft 20 is the same as one-third of the size of the arc surface of the base shaft 20. A gripping block 32 is fixedly connected to both sides of the slide rod 30. The gripping block 32 is a semi-circular block. Multiple identical gripping blocks 32 are fixedly connected to each side of the slide rod 30. A rounded corner block 33 is fixedly connected to the front wall of the slide rod 30. The rounded corner block 33 is a semi-circular block. When the bottom of the slide rod 30 contacts the top of the bone rod 27, the bottom of the rounded corner block 33 can be flush with the bottom of the adjustment plate 24.

[0035] In practical use, when the structure at the top of the base shaft 20 breaks, the rotation of the base shaft 20 can be controlled by inserting the broken part into the capsule-shaped groove on the front wall of the base shaft 20. When the slide bar 30 is turned, it can be turned by holding the gripping block 32.

[0036] In summary, by setting the capsule-shaped groove on the front wall of the base shaft 20, it can be used in an emergency when the device breaks and the rotation of the base shaft 20 needs to be controlled urgently. The grip block 32 and the rounded corner block 33 can reduce the sharp corners of the grip part, thereby improving the ease of operation of the slide bar 30 and preventing the sharp corners of the slide bar 30 from scratching the workers.

[0037] like Figure 1 As shown, a flanged ball valve includes a valve body 10 and a folding handle as described above, wherein the base shaft 20 is fixedly connected to the valve stem of the valve body 10 at its bottom.

[0038] By setting a folding handle, the valve stem of the valve body 10 can be controlled to rotate manually even in confined spaces.

[0039] Working principle: When it is necessary to control the rotation of the base shaft 20, slide the slide rod 30 in one direction where there is room to rotate. When the slide rod 30 slides, it will drive the connecting column 31 to slide synchronously along the slide groove 28. As the slide rod 30 gradually slides, the end of the bone rod 27 will align with the opening of the slide rod 30. At this time, the slide rod 30 can be turned in the desired direction, and the bone rod 27 will drive the adjusting plate 24 and the fixed plate 21 to contact, and then drive the base shaft 20 to rotate. After the slide rod 30 is used, slide the slide rod 30 back in the original direction. When it slides to the original position, the magnet on the wall of the connecting plate 29 will attract the bottom of the slide rod 30, thereby fixing the position of the slide rod 30.
