[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0017] See also Figures 1 to 3 , which is the first embodiment of the present invention, and provides a technical solution: a long-handled purse-string pliers with flexible angle adjustment, comprising a first pliers handle 1 and a second pliers handle 2 rotatably connected together by a rotating shaft, wherein the first pliers handle 1 and the second pliers handle 2 are rotated to realize the biting action of the first pliers head 4 and the second pliers head 3, and the left ends of the first pliers handle 1 and the second pliers handle 2 are respectively equipped with the first pliers head 4 and the second pliers head 3, and the ends of the second pliers head 3 and the first pliers head 4 are both equipped with toothed chucks 6 for subsequent clamping actions, and angle adjustment mechanisms 5 are provided between the first pliers handle 1 and the first pliers head 4 and between the second pliers handle 2 and the second pliers head 3, so that the angle between the pliers head and the pliers handle can be flexibly adjusted by rotation;

[0018] The angle adjustment mechanism 5 includes a rotating head 51, a U-shaped notch 52, a bolt 53, a nut 54 and an annular gear ring 55. One end surface of the second pliers head 3 and the first pliers head 4 are both provided with an integrated rotating head 51, and the left end surfaces of the first pliers handle 1 and the second pliers handle 2 are both provided with a U-shaped notch 52 corresponding to the rotating head 51. The rotating head 51 is rotatably installed in the U-shaped notch 52 by the bolt 53 to achieve smooth rotation of the rotating head 51. The nut 54 is sleeved and installed on one end of the bolt 53. Due to the U-shaped design of the left ends of the first pliers handle 1 and the second pliers handle 2, when the nut 54 is tightened, the left ends of the first pliers handle 1 and the second pliers handle 2 will undergo a certain deformation, thereby pressing the rotating head 51 to achieve the limitation of the rotating head 51. Annular gear rings 55 are fixed on both side surfaces of the rotating head 51, and gear ring grooves 56 corresponding to the annular gear ring 55 are provided on the inner walls on both sides of the U-shaped notch 52, so that after the nut 54 is tightened, the annular gear ring 55 will be embedded in the gear ring groove 56 to stably limit the rotating head 51.

[0019] Among them, the surfaces of the rotating head 51, the first pliers handle 1 and the second pliers handle 2 are all provided with through holes, and the through holes are adapted to the bolts 53 for the smooth passage of the bolts 53. The right end surfaces of the first pliers handle 1 and the second pliers handle 2 are both provided with pliers rings for subsequent operators to take the pliers, and a rack is provided on the pliers rings.

[0020] In summary, when the long-handled purse-string pliers are in use, the first pliers handle 1 and the second pliers handle 2 can be rotated and swung to realize the biting or opening action of the second pliers head 3 and the first pliers head 4. At the same time, the angle between the pliers head and the pliers handle can be flexibly adjusted according to different usage requirements. When adjusting, first loosen the nut 54 so that the left ends of the first pliers handle 1 and the second pliers handle 2 are no longer in tight contact with the rotating head 51, causing the annular gear ring 55 to move out of the gear ring groove 56, and the limit on the rotating head 51 can be released. At this time, the second pliers can be The head 3 and the first pliers head 4 are rotated at an angle through the rotating head 51. When adjusted to a suitable angle, the nut 54 is rotated and tightened again, so that the left ends of the first pliers handle 1 and the second pliers handle 2 are squeezed and deformed to a certain extent, and fit tightly with the rotating head 51, and the annular gear ring 55 is stuck in the gear ring groove 56, so that the stable positioning of the rotating head 51 can be achieved, and the stable positioning of the second pliers head 3 and the first pliers head 4 after rotation can be achieved, thereby changing the angle between the pliers head and the pliers handle, which is convenient for different usage environments and needs. Example

[0021] See also Figures 1 to 5 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the second clamp 3 and the first clamp 4 can be connected together through a limiting telescopic rod 7, so that the second clamp 3 and the first clamp 4 can be rotated simultaneously for angle adjustment and keep the second clamp 3 and the first clamp 4 aligned at all times.

[0022] Specifically, a limiting telescopic rod 7 is rotatably installed between the second clamp head 3 and the first clamp head 4 to ensure that the second clamp head 3 and the first clamp head 4 can be rotated at the same time for angle adjustment, and when the second clamp head 3 and the first clamp head 4 are subsequently rotated to open and close, the limiting telescopic rod 7 will also rotate accordingly without affecting the smooth engagement of the two clamp heads. The limiting telescopic rod 7 consists of a bottom sliding sleeve and a top sliding rod. The bottom end of the top sliding rod is slidably installed in the bottom sliding sleeve. A connecting mechanism 71 is provided between the limiting telescopic rod 7 and the first clamp head 4 and between the limiting telescopic rod 7 and the second clamp head 3.

[0023] When the lock is unlocked, the locking lever 720 is unlocked, and the locking lever 720 is unlocked, so that the lock is unlocked, and the winch 7 is unlocked, so that the winch 7 can be unlocked.

[0024] Among them, an L-shaped rubber pad 715 is fixed to one side surface of the T-shaped plug 714, and the L-shaped rubber pad 715 extends to the surface of the slide 713. The inner surface of the L-shaped rubber pad 715 is provided with an integrated circular protrusion 717, and the surface of the slide 713 is provided with a rectangular slot 718 corresponding to the circular protrusion 717. The circular protrusion 717 is embedded in the rectangular slot 718 to realize auxiliary limiting of the T-shaped plug 714 during daily use.

[0025] In summary, when the limiting telescopic rod 7 needs to be removed for inspection and replacement later, it is only necessary to pull the T-shaped plug block 714 to separate the L-shaped rubber pad 715 from the slide seat 713, and move the end of the T-shaped plug block 714 out of the annular groove 716 to release the limit on the limiting telescopic rod 7. At this time, the limiting telescopic rod 7 can be moved sideways and directly separated from the rotating seat 711 and the shaft rod 712, thereby realizing the rapid disassembly of the limiting telescopic rod 7 and ensuring the convenience of subsequent maintenance.

[0026] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
