However, when the metal pipe is bent, the bending angle at the connecting joint is limited and it is easy to be damaged. There is no device for buffering and protecting the connection.

DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] Example: Figure 1-5 As shown, the utility model provides a bending-resistant metal pipe of a joint protection device, including a pipe 1, a connecting piece 11 is fixedly installed at one end of the pipe 1, a first fixing ring 2 is fixedly installed on one side of the connecting piece 11, a second fixing ring 3 is provided on one side of the first fixing ring 2, and a plurality of first springs 31 distributed in an array are fixedly installed on one end, a first limiting ring 32 is fixedly installed on one end of the plurality of first springs 31, a plurality of second springs 321 distributed at equal intervals are fixedly installed on the inner wall of one side of the first limiting ring 32, a second limiting ring 322 is fixedly installed on one end of the plurality of second springs 321 away from the first limiting ring 32, and one end of the second limiting ring 322 away from the second spring 321 contacts the outer wall of the pipe 1.
[0019] A fourth spring 34 is fixedly installed on the outer surface of one side of the second fixing ring 3, and a third fixing ring 4 is fixedly installed on the other end of the fourth spring 34. The inner wall of the third fixing ring 4 contacts the outer surface of the second fixing ring 3. A plurality of first limiting grooves 35 distributed in an array are provided on one side of the second fixing ring 3, and second limiting beads 351 are slidably clamped inside the plurality of first limiting grooves 35. By setting the first limiting grooves 35, the diameter of the inner wall of the first limiting groove 35 close to the second fixing ring 3 is opened to be smaller than the second limiting bead 351, thereby preventing the second limiting bead 351 from falling from one side of the inner wall of the first limiting groove 35.
[0020] A third spring 33 is fixedly installed on one side of the second fixing ring 3 close to the first spring 31 , and a first limiting bead 331 is fixedly installed on the other end of the third spring 33 . By setting the third spring 33 , the first spring 31 can be ejected under the reaction force of the third spring 33 .
[0021] A plurality of second limiting holes 41 distributed in an array are provided on the inner wall of one side of the third fixing ring 4, and a plurality of first limiting beads 331 are slidably clamped inside the second limiting holes 41. By setting the second limiting holes 41, while completing the fixation of the second fixing ring 3, the second limiting hole 41 is located in front of the first limiting beads 331. Under the reaction force of the first spring 31, the first limiting beads 331 are clamped inside the second limiting holes 41, thereby limiting the third fixing ring 4.
[0022] A second limiting groove 42 is provided on the inner wall of the second fixing ring 3 on the side away from the first spring 31. By providing the second limiting groove 42, when the second fixing ring 3 is pushed toward the first fixing ring 2, the second limiting bead 351 will first enter the interior of the second limiting groove 42 due to the squeezing of the first fixing ring 2, so that the second fixing ring 3 is smoothly pushed toward the first fixing ring 2.
[0023] Two symmetrically distributed first sliders 36 are fixedly installed on the inner wall of one side of the second fixing ring 3, and two symmetrically distributed slide grooves 22 are opened on one side of the first fixing ring 2. The first slider 36 is slidably clamped inside the slide groove 22. By setting the first slider 36, when the second fixing ring 3 is pushed toward the first fixing ring 2, the first slider 36 is slidably inserted into the slide groove 22, thereby avoiding rotation when the second fixing ring 3 is moved toward the first fixing ring 2, and it is not easy to align the second limiting bead 351 with the first limiting hole 21.
[0024] A plurality of first limiting holes 21 distributed in an array are provided on one side outer wall of the first fixing ring 2, and a plurality of second limiting beads 351 are slidably clamped inside the first limiting holes 21. By setting the first limiting hole 21 and sliding the second limiting beads 351 inside the first limiting hole 21, the second fixing ring 3 is fixed.
[0025] A third limiting groove 43 is provided on the inner wall of one side of the third fixing ring 4, and the fourth spring 34 is slidably clamped inside the third limiting groove 43. By setting the third limiting groove 43, the fourth spring 34 is slidably clamped inside the third limiting groove 43, and the third fixing ring 4 is pushed under the action of the third limiting groove 43.
[0026] Working principle: In actual use, when the pipe 1 bends and contracts, the outer wall of the pipe 1 and the second limiting ring 322 come into contact with each other, and the bending of the pipe 1 is firstly buffered by the reaction force of the second spring 321, and then the force is transmitted to the first spring 31 through the first limiting ring 32, and the bending of the pipe 1 is buffered by the reaction force of the first spring 31;
[0027] By pulling the third fixing ring 4, the second limiting groove 42 is located directly behind the second limiting bead 351, and the second fixing ring 3 is moved in the direction of the first fixing ring 2. When the specified position is reached, the third fixing ring 4 is released, and the third fixing ring 4 is moved in the direction of the first fixing ring 2 under the reaction force of the fourth spring 34, so that the second limiting bead 351 is clamped inside the first limiting hole 21, thereby completing the fixation of the second fixing ring 3.
[0028] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
