For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figures 1 to 4 As shown, the sleeve adjustment structure of the utility model includes: a sleeve body 1, the sleeve body 1 has a separable first part 11 and a second part 12; wherein the first part 11 is formed with a thread groove 111 at one end facing the second part 12, and the second part 12 is formed with an extension part 121 facing the first part 11, and the surface of the extension part 121 is provided with a thread matching the thread groove 111; a reinforcement plate 2, the reinforcement plate 2 is arranged on the outer surface of the second part 12, and when the first part 11 and the second part 12 are away from each other, the reinforcement plate 2 at least blocks part of the extension part 121.

[0035] See also Figures 1 to 3The reinforcing plate 2 is sleeved on the outer surface of the second part 12. The reinforcing plate 2 has a channel with the same diameter as the middle of the first part 11 and the second part 12. The reinforcing plate 2 is used to reinforce the extension part 121 to prevent external parts from touching the extension part 121 and causing damage to it, thereby affecting the service life of the sleeve body 1.

[0036] When the length of the sleeve body 1 needs to be changed, the second part 12 is rotated relative to the first part 11. Since the extension part 121 of the second part 12 is in a threaded connection with the first part 11, the second part 12 is moved away from the first part 11 to achieve the change of the length of the sleeve body 1. It has the characteristics of simple structure and convenient operation.

[0037] In one or more embodiments, a limiting mechanism is further included between the first part 11 and the second part 12. When the distance between the first part 11 and the second part 12 along the axial direction is fixed, the limiting mechanism is used to limit the relative rotation of the first part 11 and the second part 12. The limiting mechanism includes: a countersunk hole 31, a through hole 33, a stepped layer 35 and a blocking unit; the countersunk hole 31 is arranged at the bottom of the first part 11, and the countersunk hole 31 is provided with a support block 32, and the support block 32 is threadedly connected with the countersunk hole 31; the through hole 33 vertically passes through the top of the first part 11 through the countersunk hole 31, and the through hole 33 is located on the side close to the central axis of the first part 11 relative to the thread groove 111, and a blocking rod 34 is arranged in the through hole 33, and the blocking rod 34 is rotatably mounted on the support block 32; the stepped layer 35 is formed at the bottom of the second part 12, and is located on the side close to the central axis of the second part 12 relative to the extension portion 121; the blocking unit is arranged on the stepped layer 35 to connect the blocking rod 34 and the second part 12.

[0038] See also Figures 2 to 4 The countersunk hole 31 is opened from the bottom of the first part 11 to the top of the first part 11, and the depth of the countersunk hole 31 is roughly equivalent to the depth of the thread groove 111 of the first part 11, so that the maximum height to which the support block 32 supports the blocking rod 34 to rise can be equivalent to the farthest distance between the first part 11 and the second part 12, so that the blocking rod 34 is connected to the second part 12 through the blocking unit, thereby limiting the rotation of the second part 12 relative to the first part 11, fixing the adjusted distance between the second part 12 and the first part 11, and improving the use effect of the present application.

[0039] When the spacing between the second part 12 and the first part 11 is adjusted, the six head holes at the bottom of the support block 32 are used to control the rotation of the support block 32. Since the support block 32 and the countersunk hole 31 are threadedly connected, the support block 32 can rise in the countersunk hole 31, and then the blocking rod 34 is lifted by the support block 32, so that the blocking unit at the top of the blocking rod 34 is connected to the step layer 35 of the second part 12, and the first part 11 and the second part 12 are snapped together, so that the adjusted spacing between the second part 12 and the first part 11 is fixed.

[0040] In other possible embodiments, the support block 32 is not threadedly connected to the side wall of the countersunk hole 31, and the top surface of the support block 32 is connected to the top surface of the countersunk hole 31 through an elastic member, and a handle is installed on the bottom surface of the support block 32. In the initial state, under the action of the elastic member, the support block 32 pushes the blocking rod 34 to rise to a static position, so that the blocking unit at the top of the blocking rod 34 is connected to the second part 12 to achieve a clamping effect. In this way, it has the characteristics of simple structure and convenient operation.

[0041] In the first embodiment of the blocking unit, the blocking unit is a ratchet gear 351 installed on the stepped layer 35 and a blocking block 352 arranged at the end of the blocking rod 34 , and the blocking block 352 can extend into the ratchet gear 351 .

[0042] In the second embodiment of the blocking unit, the blocking unit is a limiting hole opened on the stepped layer 35, and the top of the blocking rod 34 can extend into the limiting hole. It should be noted that there are a plurality of limiting holes, and when the second part 12 rotates, the top of the blocking rod 34 can still be inserted into the limiting hole at a predetermined position.

[0043] In one or more embodiments, the reinforcing plate 2 is detachably mounted on the second portion 12 by screws. With this arrangement, the reinforcing plate 2 can be replaced. When the second portion 12 is relatively far away from the first portion 11, a gap will appear between the second portion 12 and the first portion 11 due to the distance of the reinforcing plate 2. By replacing the reinforcing plate 2 with a matching size, the gap can be blocked, thereby realizing the protection of the outer wall of the first portion 11 by the reinforcing plate 2.

[0044] In one or more embodiments, the reinforcing plate 2, the stopper rod 34, the stopper 352, and the ratchet gear 351 are made of steel. Through this arrangement, the connection strength between the first part 11 and the second part 12 can be ensured, and the service life of the sleeve body 1 can be improved.

[0045] In one or more embodiments, the depth of the thread groove 111 is 5-15 cm. The depth of the thread groove 111 can be 5 cm, 10 cm, or 15 cm, without limitation.

[0046] In one or more embodiments, the outer surface of the reinforcing plate 2 disposed outside the second portion 12 is flush with the circumferential surface of the first portion 11. This arrangement can ensure the installation of the sleeve body 1 and improve the application range of the sleeve body 1.

[0047] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
