[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] This utility model provides a sleeve, such as Figure 1 , Figure 2As shown, the device includes a cylindrical body 1 with one open end. The inner wall of the cylindrical body 1 is provided with internal threads for threaded connection with corresponding components. The cylindrical body 1 is provided with an inner cylinder 2, which is composed of a first inner cylinder 3 and a second inner cylinder 4 that are slidably connected. The first inner cylinder 3 is tightly fitted to the cylindrical body 1 to ensure the stability of the structure. A sliding assembly 5 is provided on the outer wall of the cylindrical body 1. The sliding assembly 5 includes a first slider 6, a second slider 7, a first limiting block 8, and a second limiting block 16. The outer wall of the cylindrical body 1 is provided with two receiving grooves 9. The sliding assembly 5 is slidably connected to the receiving grooves 9. The bottom of each receiving groove 9 is provided with an L-shaped through groove 10. A part of the sliding assembly 5 is slidably connected to the through groove 10. This design allows the sliding assembly 5 to slide flexibly within a specific range to meet different usage requirements.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, a reinforcing rod is provided between the slider and the limiting block. The first reinforcing rod 11 is fixed between the first slider 6 and the first limiting block 8 and is slidably connected to the through groove 10. The second reinforcing rod 17 is fixed between the second slider 7 and the second limiting block 16. The setting of the reinforcing rod enhances the connection strength between the slider and the limiting block and improves the stability and reliability of the entire sliding assembly 5.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, the outer wall of the first inner cylinder 3 is provided with a first limiting groove 12 and a through hole 13. The first limiting block 8 is slidably connected to the first limiting groove 12. The outer wall of the second inner cylinder 4 is provided with a second limiting groove 18. The second limiting block 16 is slidably connected to the second limiting groove 18, and the second reinforcing rod 17 is slidably connected to the through hole 13. Through this sliding connection, the inner cylinder 2 can be extended and adjusted to a certain extent during use. The rear end of the cylinder 1 is provided with anti-slip ridges 14, which increases the friction during operation and prevents slippage. The cylinder 1 is made of high-strength alloy steel, which has good strength and wear resistance. The surface of the slider is evenly distributed with multiple protrusions 15 made of rubber material, which further increases the friction and comfort during operation. The first inner cylinder 3 and the second inner cylinder 4 have the same length. The inner diameter of the first inner cylinder 3 is 1-3cm, and the inner diameter of the second inner cylinder 4 is 0.8-2.5cm.

[0020] Working principle: First, the internal threads on the inner wall of the cylinder 1 are used for threaded connection with external components, achieving fastening and fixation. The design of the inner cylinder 2, especially the close-fitting structure of the first inner cylinder 3 and the second inner cylinder 4, increases the adaptability of the sleeve. When it is necessary to accommodate components of different sizes, the first inner cylinder 3 and the second inner cylinder 4 can slide relative to each other to adjust the size of the internal accommodating space. The sliding component 5 on the outer wall of the cylinder 1, including a slider and a limiting block, can change the nut specification corresponding to the sleeve by sliding within the accommodating groove 9, to adapt to different working environments and operational requirements. For example, when it is necessary to screw... When turning a smaller nut, slide the slider outward. The presence of the reinforcing rod ensures the stability and connection strength of the slider and the limiting block during the sliding process, preventing loosening or detachment. The sliding connection between the limiting groove on the outer wall of the first inner cylinder 3 and the limiting block ensures the accuracy and stability of the inner cylinder 2 during telescopic adjustment, avoiding misalignment or displacement. The anti-slip thread at the rear end of the cylinder 1 increases friction during operation, preventing hand slippage and improving the safety and accuracy of operation. The rubber protrusions 15 on the surface of the slider further enhance friction, making operation easier and more reliable.
