Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0021] Embodiment 1

[0022] As Figs. 1-3 The utility model discloses a kind of expansion water pipe breakage extractors, including cylindrical sleeve 1, sleeve 1 both ends are equipped with progressive advancing mechanism, both sides progressive advancing mechanism are connected with circular table 2 in sleeve 1 inside, circular table 2 is coaxial with sleeve 1 and circular table 2 radius is retracted to sleeve 1 inside;A plurality of axial central symmetrical long slot holes 3 are perforated on the outer wall of sleeve 1, and the long side of slot hole 3 is parallel to the axis of sleeve 1, expansion rack 4 is slidably connected in slot hole 3, and expansion rack 4 bottom is equipped with the inclined surface that is attached to the sidewall of both sides circular table 2.

[0023] Among them, progressive advancing mechanism is two advancing bolts 5 respectively screwed into the both ends of sleeve 1, and same side advancing bolt 5 is coaxially fixedly connected between same side advancing bolt 5 and circular table 2. Knob 6 is rotatably connected on at least one end of sleeve 1, and knob 6 is threadedly connected between same side advancing bolt 5. Power shaft connecting bayonet 7 is formed in the middle of at least one side advancing bolt 5.

[0024] Among them, one side circular table 2 is coaxially fixedly connected with spring sleeve shaft 8 on one side circular table 2, compression spring 9 is sleeved on spring sleeve shaft 8, and one end of compression spring 9 is fixed on same side circular table 2;Another side circular table 2 is coaxially provided with sleeve sleeve hole 10 on another side circular table 2.

[0025] Among them, the top of expansion rack 4 is circular arc shape in the axial direction of sleeve 1.

[0026] In use, the sleeve 1 is placed in the broken water pipe to be extracted, and then the degree of advancement of the advancing bolt 5 in the sleeve 1 is adjusted, which can be adjusted using the knob 6 or the power shaft connection bayonet 7. When the advancing bolt 5 advances into the sleeve 1, the side wall of the circular table 2 on the advancing bolt 5 pushes the expansion spline 4 out of the slot hole 3, thereby clamping the broken water pipe. In addition, the depth of the expansion spline 4 in the broken water pipe can be adjusted to adjust the clamping tightness. During adjustment, the compression spring 9 is compressed between the two circular tables, thereby further tightening the connection between the advancing bolt 5 and the sleeve 1.

[0027] In this embodiment, the advancing bolt 5 is used to control the precise adjustment of the force. According to the actual situation of the broken water pipe, the user can gradually increase or decrease the pressure by adjusting the rotation of the advancing bolt 5, thereby avoiding the problems of excessive force leading to pipe damage or insufficient force leading to the inability to fix the broken head in the traditional broken head extractor. The progressive advancement mechanism makes the force distribution more uniform, ensuring that the broken head can be smoothly extracted without causing secondary damage to the water pipe.

[0028] In this embodiment, the adjustable expansion spline 4 is used. By adjusting the advancing bolts 5 at both ends of the sleeve, the protrusion of the expansion spline 4 in the slot hole can be flexibly adjusted. In addition, since the top of the expansion spline 4 is arc-shaped along the axial direction of the sleeve 1, the depth of the expansion spline 4 in the water pipe can be adjusted. The protrusion and depth of the expansion spline 4 can adaptively clamp water pipes of different sizes, making the device more adaptable and able to handle pipes of different diameters and materials, enhancing the versatility of the equipment and reducing the user's need for multiple tools.

[0029] In this embodiment, the expansion spline 4 can firmly grasp the broken head or residue in the pipe and stably fix it during the advancement process. The combination of the side wall of the circular table 2 and the inclined surface at the bottom of the expansion spline 4 ensures a strong clamping force in the pipe, making it possible to effectively fix and smoothly extract the broken head even in deep or complex pipe environments, significantly improving the success rate of extraction.

[0030] In this embodiment, the compression spring 9 can maintain a compressed state when the advancing bolts 5 on both sides advance inward, thereby providing a counteracting force to the advancing bolts 5 on both sides, making the connection between the advancing bolts 5 on both sides and the sleeve 1 more secure and reducing the likelihood of errors or damage during operation.

In addition, there is no spring sleeve shaft 8, compression spring 9 and sleeve shaft hole 10 structure.
