[0024] Please see Figure 2 and Figure 4 In this embodiment, a fixing ring 101 is provided in the middle of the inner side of the main sleeve 1, and the bidirectional lead screw 4 is rotatably connected to the fixing ring 101. A guide rod 102 is provided in the inner side of the main sleeve 1, and multiple sets of guide rods 102 are provided. The guide rods 102 and the bidirectional lead screw 4 are distributed equidistantly in a ring on the inner side of the main sleeve 1. A second connecting block 201 is provided on the outer side of the rear end of the auxiliary sleeve 2. The second connecting block 201 is slidably connected to the guide rod 102. Multiple sets of second connecting blocks 201 are provided. The second connecting block 201 and the first connecting block 3 are distributed equidistantly in a ring on the outer side of the rear end of the auxiliary sleeve 2. The fixing ring 101 limits the contraction position of the auxiliary sleeve 2. The extension and retraction of the auxiliary sleeve 2 drives the second connecting block 201 to slide along the guide rod 102. The guide rod 102 ensures the stable displacement of the auxiliary sleeve 2.
[0025] Please see Figure 3 and Figure 5In this embodiment, a through groove 501 is provided on one side of the middle part of the main sleeve 1. The driven gear 5 is disposed inside the through groove 501 and the fixing ring 101. The driven gear 5 can pass through the main sleeve 1 and rotate through the through groove 501. A rotating shaft 701 is provided through the inner side of the drive gear 7. Both ends of the rotating shaft 701 pass through the protective shell 6. The rotating shaft 701 is rotatably connected to the protective shell 6. A turntable 702 is provided at both ends of the rotating shaft 701. Rotating the turntable 702 drives the rotating shaft 701 to rotate. Rotating the rotating shaft 701 drives the drive gear 7 to rotate, thereby flexibly controlling the extension and retraction of the secondary sleeve 2. Slide grooves 1001 are symmetrically provided at both ends of the inner side of the fixing frame 8. Slide blocks 1002 are symmetrically provided at both ends of the outer side of the locking tooth 10. The slide blocks 1002 are engaged and slid along the slide grooves 1001. When the locking tooth 10 is raised or lowered, the slide blocks 1002 are driven to slide along the slide grooves 1001 to ensure the stable raising and lowering of the locking tooth 10.
[0026] Please see Figure 4 In this embodiment, a receiving groove 1101 is provided on the inner side of the front end of the secondary sleeve 2. A second adjusting screw 1102 is provided through the front end of the secondary sleeve 2. The second adjusting screw 1102 is threadedly connected to the secondary sleeve 2. The bottom end of the second adjusting screw 1102 is located on one side of the receiving groove 1101. An arc-shaped pressure plate 1103 is provided at the bottom end of the second adjusting screw 1102. The second adjusting screw 1102 is rotatably connected to the arc-shaped pressure plate 1103. The arc-shaped pressure plate 1103 is located on the inner side of the receiving groove 1101. Rotating the second adjusting screw 1102 flexibly adjusts the position of the arc-shaped pressure plate 1103. The arc-shaped pressure plate 1103 is received by the receiving groove 1101. Pressing down the arc-shaped pressure plate 1103 locks one end of the secondary sleeve 2 to the outer wall of the pipe, thus fixing the installation position of the secondary sleeve 2.
[0027] When adjusting the secondary sleeve 2, the main sleeve 1 is sleeved outside the pipe. Rotating the turntable 702 drives the rotating shaft 701 to rotate around the protective shell 6. Rotating the rotating shaft 701 drives the drive gear 7 to rotate, so that the drive gear 7 passes through the through groove 501 and drives the driven gear 5 to mesh and rotate.
[0028] Subsequently, rotating the driven gear 5 drives the bidirectional lead screw 4 to rotate. Rotating the bidirectional lead screw 4 adjusts the spacing of the first connecting block 3, thereby driving the secondary sleeve 2 to flexibly extend and retract on the fixing ring 101 inside the main sleeve 1, so that the second connecting block 201 slides synchronously along the guide rod 102.
[0029] After the secondary sleeve 2 and the main sleeve 1 are adjusted to the appropriate length, the first adjusting screw 9 on the fixing frame 8 is rotated to lower the placement height of the locking tooth 10, thereby driving the slider 1002 to slide down synchronously along the slide groove 1001, so that the locking tooth 10 locks the drive gear 7, locking the position of the drive gear 7, thereby locking the length of the main sleeve 1 and the secondary sleeve 2.
[0030] Finally, rotate the second adjusting screw 1102 to press down the arc-shaped pressure plate 1103, and move the arc-shaped pressure plate 1103 slightly out of the receiving groove 1101 so that the arc-shaped pressure plate 1103 presses against the outer wall of the pipe, locking the positions of the main sleeve 1 and the auxiliary sleeve 2, and protecting the pipe through the main sleeve 1 and the auxiliary sleeve 2.
[0031] Through the above steps, the main sleeve 1 is fitted onto the outside of the pipeline. The protective shell 6 is used to fix the position of the drive gear 7. Rotating the drive gear 7 drives the driven gear 5 to mesh and rotate. Rotating the driven gear 5 drives the bidirectional screw 4 to rotate. Rotating the bidirectional screw 4 adjusts the spacing of the first connecting block 3. The first connecting block 3 is used to connect and fix the auxiliary sleeve 2, thereby controlling the flexible extension and retraction of the auxiliary sleeve 2 within the main sleeve 1. The fixing bracket 8 is used to fix the position of the first adjusting screw 9. After adjusting the main sleeve 1 and the auxiliary sleeve 2 to a suitable length, the first adjusting screw 9 is used to connect and fix the locking teeth 10. Rotating the first adjusting screw 9 adjusts the placement height of the locking teeth 10. The locking teeth 10 lock the drive gear 7, locking its position and thus locking the position of the auxiliary sleeve 2. The pipeline is protected by the main sleeve 1 and the auxiliary sleeve 2. The sleeve length can be flexibly adjusted according to the required pipeline length. The operation is simple and convenient, ensuring effective protection operations, expanding the applicable range of the sleeve, and improving the flexibility of sleeve use.
[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
