[0025] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0026] Embodiment 1:

[0027] This embodiment provides a multifunctional broken wire extractor for water pipes, which is characterized by comprising:

[0028] A main body 1, one end of which is provided with a tap 2, and the other end is a rotating part 3;

[0029] A square hole 5, which is arranged on the end surface of the rotating part 3;

[0030] A fixing hole 6, which is opened along the radial direction of the rotating part 3 and communicates with the square hole 5;

[0031] The hexagonal portion 7 is provided on the outer wall of the rotating portion 3 .

[0032] The main body 1 is an integrated structure and is made of high-strength alloy. One end of the main body 1 is a tap 2 and the other end is a rotating part 3. A square hole 5 is provided on the end face of the rotating part 3. The square hole 5 can be connected to an electric drill or a manual wrench and rotated through the square hole 5. The fixing hole 6 is opened radially along the rotating part 3 and is connected to the square hole 5. When inserting the joint into the square hole 5, a pin can be set to pass through the fixing hole 6 to penetrate the joint to the other end of the rotating part 3 to achieve a fixed connection between the rotating part 3 and the joint, so that the joint is not easy to fall out of the square hole 5 when rotating. A hexagonal part 7 is formed on the outer wall of the rotating part 3. A wrench can be used to clamp the hexagonal part 7 to rotate the main body 1. The tap 2 is carefully placed on the position of the broken thread to ensure that it is consistent with the direction and angle of the thread residue. Gently rotate the tap 2 and gradually move it downward until it begins to cut and remove the residue of the broken thread.

[0033] When one of the driving modes is damaged, it can be replaced by another alternative driving mode, or when a large torque is required, the hexagonal portion 7 can be screwed by a wrench and then screwed by the electric driving mode.

[0034] Embodiment 2:

[0035] This embodiment provides a multifunctional broken wire remover for water pipes, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0036] The hexagonal portion 7 and the square hole 5 are arranged at different positions on the axis.

[0037] The hexagonal portion 7 and the square hole 5 are arranged at different positions on the axis, that is, positions without overlap, so that the position of the hexagonal portion 7 is solid and has greater hardness.

[0038] The corners of the square hole 5 are rounded 8 .

[0039] The rounded corner 8 can reduce the collision between the joint and the square hole 5, and can protect the joint.

[0040] The size of the tap 2 is one-quarter or one-sixth.

[0041] Furthermore, it also includes:

[0042] A fixing device is provided on the inner wall of the fixing hole 6, and the fixing device includes: a spring groove 9, which is provided on the inner wall of the fixing hole 6, and the inner diameter of the opening of the spring groove 9 is smaller than the diameter of the spring groove 9; a fixing ball 12, which is provided in the spring groove 9 and abuts against the opening of the spring groove 9; a fixing spring 10, which is provided between the fixing ball 12 and the bottom of the spring groove 9; and a fixing pin 13, which is provided with a clamping groove 14 that cooperates with the fixing ball 12.

[0043] Multiple fixing devices can be provided symmetrically to enhance stability.

[0044] The fixing pin 13 penetrates the joint to realize the connection between the joint and the extractor, and the fixing device prevents the fixing pin 13 from shifting and preventing the fixing pin 13 from being thrown out and injuring people during rotation.

[0045] During disassembly, the fixing pin 13 is rotated and then withdrawn.

[0046] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific embodiments. The above-mentioned specific embodiments are merely illustrative and not restrictive.
