[0030] Specifically, the fixed tube 1 provides a stable sliding track for the mobile tube 17, and the mobile tube 17 can slide freely inside the fixed tube 1, so that the equipment has greater flexibility during operation. A threaded groove 3 is designed on the right side of the inner wall of the mobile tube 17, so that the mobile tube 17 can be precisely threadedly connected with other components. A groove 4 is opened on the right side of the outer wall of the mobile tube 17. The sealing gasket 5 installed on the inner side of the groove 4 ensures the sealing of the connection part and effectively prevents possible leakage. An extension tube 7 is also provided inside the mobile tube 17. A threaded ring 6 is fixedly connected to the left side of the outer wall of the extension tube 7, and the right side of the sealing gasket 5 is fixedly connected to the threaded ring 6. In this way, when the extension tube 7 is threadedly connected to the threaded groove 3 on the inner wall of the mobile tube 17 through the threaded ring 6, the sealing gasket 5 plays a key sealing role and ensures the stability and sealing of the connection part.

[0031] Reference Figure 1 and Figure 3 The positioning mechanism 2 includes a bottom plate 201, which is arranged at the bottom of the fixed tube 1. A second fixed block 203 is fixedly connected to the left side of the top of the bottom plate 201. The top of the second fixed block 203 is fixedly connected to the fixed tube 1. A first fixed block 202 is fixedly connected to the right side of the top of the bottom plate 201. The top of the first fixed block 202 is fixedly connected to the moving tube 17. The front and rear sides of the right end of the second fixed block 203 are fixedly connected to a guide rod 204. The right side of the guide rod 204 passes through the first fixed block 202 and is fixedly connected to a fixed plate 205. The left side of the fixed plate 205 is fixedly connected to the bottom plate 201.

[0032] Specifically, the bottom plate 201 is arranged at the bottom of the fixed tube 1, and the left side of the top end of the bottom plate 201 is fixedly connected to the second fixed block 203, so that the second fixed block 203 can stably support and fix the fixed tube 1 above, and the front and rear sides of the right end of the second fixed block 203 are fixedly connected with the guide rod 204. The function of the guide rod 204 is to provide stable guidance and support to ensure that the structure can remain stable during movement or operation. The right side of the guide rod 204 passes through the first fixed block 202 and is fixedly connected to the fixed plate 205. The first fixed block 202 can move along the guide rod 204 and maintain its relative position with the bottom plate 201 unchanged. At the same time, the top of the first fixed block 202 is fixedly connected to the mobile tube 17. When the mobile tube 17 needs to move or adjust its position, the first fixed block 202 moves accordingly to maintain stability while achieving flexible operation and adjustment.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A slide bar 15 is fixedly connected to the middle of the top of the bottom plate 201, a slide groove 16 is provided at the bottom of the first fixed block 202, and the first fixed block 202 is slidably connected to the slide bar 15 through the slide groove 16; positioning blocks 13 are fixedly connected to the four corners of the outer wall of the bottom plate 201, and positioning holes 14 are provided on the outer sides of the multiple positioning blocks 13; flange rings 9 are fixedly connected to the outer sides of the fixed tube 1 and the extension tube 7, and multiple screws 10 are threadedly connected to the outer sides of the flange rings 9;

[0034] Specifically, a slide bar 15 is fixedly connected to the middle part of the top of the bottom plate 201. The function of the slide bar 15 is to provide a sliding track for the first fixed block 202. A slide groove 16 matching the slide bar 15 is provided at the bottom of the first fixed block 202. When the first fixed block 202 needs to slide along the slide bar 15, the slide groove 16 will play a guiding and supporting role to ensure that the first fixed block 202 can move steadily and smoothly. The four corners of the outer wall of the bottom plate 201 are fixedly connected with positioning blocks 13. The outer side of the positioning block 13 is provided with a positioning hole 14. The function of the positioning hole 14 is to provide a positioning reference for other components to ensure that they can be accurately installed in the specified position. The outer side of the connection method of the fixed tube 1 and the extension tube 7 is fixedly connected with a flange ring 9. On the outer side of the flange ring 9, there are multiple screws 10 threadedly connected. The screws 10 can tightly connect the two flange rings 9 together, thereby further improving the firm connection between the fixed tube 1 and the extension tube 7.

[0035] Reference Figure 1 and Figure 2 A pad 18 is fixedly connected to the outside of the fixed tube 1; a handle 11 is fixedly connected to the top of the pad 18, and a cushion 12 is fixedly connected to the outside of the handle 11; a hose 8 is fixedly connected to the left side of the inner wall of the fixed tube 1, and the right side of the outer wall of the hose 8 is fixedly connected to the middle part of the inner wall of the mobile tube 17;

[0036] Specifically, a protective pad 18 is fixedly connected to the outer side of the fixed tube 1. The presence of the protective pad 18 not only provides additional protection for the fixed tube 1 to prevent wear or impact during daily use, but also provides a comfortable gripping point for the user. A handle 11 is fixedly connected to the top of the protective pad 18, and a layer of soft pad 12 is fixedly connected to the outer side of the handle 11. The soft pad 12 not only increases the comfort of holding, but also can reduce hand fatigue caused by long-term use to a certain extent. On the left side of the inner wall of the fixed tube 1, a hose 8 is fixedly connected. The hose 8 can further enhance the protective effect of the pipes installed in the embedded pipes at a later stage. The right side of the outer wall of the hose 8 is fixedly connected to the middle part of the inner wall of the mobile tube 17. This connection method not only ensures the stability of the hose 8, but also allows it to move with the movement of the mobile tube 17.

[0037] Working principle: Before using the device, first, the mobile tube 17 is moved along the fixed tube 1 to realize the expansion and contraction of the embedded pipe. The extension tube 7 is additionally connected and fixed on the outside of the mobile tube 17 through the threaded connection between the threaded ring 6 and the threaded groove 3. At the same time, the engagement of the groove 4 and the sealing gasket 5 improves the sealing between the extension tube 7 and the mobile tube 17. In this way, without affecting the extension effect, the additional pipeline can be connected and fixed to improve the expansion and contraction effect, thereby reducing the practicality of the device. The device can be firmly fixed through the base plate 201 to improve its stability after installation and burial. The first fixed block 202 and the second fixed block 203 are connected to the fixed tube 1 and the mobile tube 17, so that when the mobile tube 17 moves, the first fixed block 202 is driven to move along the guide rod 204 on the fixed plate 205. At the same time, it is ensured that this process not only does not affect the firm fixing effect of the base plate 201 on the device, but also does not damage its stability during movement, thereby improving the reliability of the device.
