The applicant found that such a design has insufficient structural strength and is prone to deformation under external force, which can lead to internal structural interference or even damage. Utility Model Content

[0003] To achieve the above objectives, this utility model provides a sharpening cylinder assembly, including a clamping cylinder and two semi-cylindrical bodies. One end of each semi-cylindrical body is integrally formed with a side plate extending from it. The two semi-cylindrical bodies are closed and fixed together to form a first accommodating space for installing a sharpening locking assembly between the two semi-cylindrical bodies and a second accommodating space for installing a dial assembly between the two side plates. A riveting through hole is provided at the connection between the semi-cylindrical bodies and the side plates. One end of the clamping cylinder is provided with a riveting claw. The clamping cylinder is sleeved on the semi-cylindrical bodies, and the riveting claw is bent and riveted into the riveting through hole to fix the two semi-cylindrical bodies together.

[0004] In some possible embodiments, a mounting cylinder is formed at one end of the clamping cylinder, the inner diameter of the mounting cylinder being smaller than the inner diameter of the clamping cylinder and equivalent to the outer diameter of the semi-cylinder, and the riveting claw is formed at one end of the mounting cylinder.

[0005] In some possible embodiments, the semi-cylinder and the side plate are connected by a transition plate, the riveting through hole is formed between the transition plate and the side plate, and the maximum distance between the two semi-cylinders is greater than the maximum distance between the two side plates.

[0006] In some possible embodiments, one end of one of the side plates is bent to form a base plate, the end of the base plate having a positioning protrusion, and the other side plate having a positioning hole that mates with the positioning protrusion.

[0007] In some possible embodiments, the length of the semi-cylinder is greater than the length of the clamp.

[0008] In some possible embodiments, an intermediate sleeve is further included, which is fitted between the clamp and the half-cylinder. The intermediate sleeve has a semi-spiral guide groove on its side. One of the half-cylinders has an elastic protrusion on its side, which is integrally formed with the half-cylinder.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0018] Reference Figures 1 to 3 The illustrated sharpening cylinder assembly includes a clamping cylinder 1 and two semi-cylinder bodies 2. A side plate 21 is integrally formed extending from one end of each semi-cylinder body 2. The two semi-cylinder bodies 2 are closed and fixed together to form a first accommodating space for installing a sharpening locking assembly. The two side plates 21 are also closed and fixed together to form a second accommodating space for installing a dial assembly. A riveting through hole 5 is provided at the connection between the semi-cylinder bodies 2 and the side plates 21. A riveting claw 11 is provided at one end of the clamping cylinder 1. The clamping cylinder 1 is inserted into the semi-cylinder body from one end of the side plate 21. The two semi-cylinders 2 are fixedly connected by the riveting claws 11 bent and riveted into the riveting through hole 5. The cylindrical assembly of this utility model integrates the side plate 21 and the semi-cylinder 2 into one piece, which effectively improves the structural strength between the semi-cylinder 2 and the side plate 21 and avoids the problem of bending or even breaking between the side plate 21 and the semi-cylinder 2 when subjected to external force. The two semi-cylinders 2 are then fixed by the clamping sleeve 1, which solves the problems of insufficient connection strength and low assembly efficiency in the prior art. It has the advantages of simple structure, stable connection and convenient assembly.

[0019] In some possible embodiments, a mounting cylinder 12 is formed at one end of the clamping cylinder 1. The inner diameter of the mounting cylinder 12 is smaller than the inner diameter of the clamping cylinder 1 and is approximately equal to the outer diameter of the half-cylinder 2. A riveting claw 11 is formed at one end of the mounting cylinder 12. That is, the clamping cylinder 1 positions the two half-cylinders 2 by fitting the mounting cylinder 12 to ensure accurate docking of the two half-cylinders 2 during riveting. This structural design makes the connection between the clamping cylinder 1 and the half-cylinder 2 more stable, and the mounting cylinder 12 also facilitates the bending and riveting operation of the riveting claw 11.

[0020] In some possible embodiments, the semi-cylinder 2 and the side plate 21 are connected by a transition plate 22. A riveting through hole 5 is formed between the transition plate 22 and the side plate 21. The maximum distance between the two semi-cylinders 2 is greater than the maximum distance between the two side plates 21. The two semi-cylinders 2 enclose a first accommodating space in the shape of a circular hole, and the two side plates 21 form a second accommodating space in the shape of a rectangle. The transition plate 22 increases the connection strength between the semi-cylinder 2 and the side plate 21, and also provides space for the riveting through hole 5.

[0021] In some possible embodiments, one end of the side plate 21 is bent to form a base plate 23, and the end of the base plate 23 extends with a positioning protrusion 24. The other side plate 21 has a positioning hole 25 that mates with the positioning protrusion 24. This structural design makes the positioning between the two side plates 21 more accurate and also facilitates assembly operations.

[0022] In some possible embodiments, the length of the semi-cylinder 2 is greater than the length of the clamping cylinder 1. This design allows the semi-cylinder 2 to occupy more space in the sharpening cylinder assembly, enabling the sharpening locking assembly to be installed within the first receiving space and to reciprocate axially.

[0023] In some possible embodiments, an intermediate sleeve 6 is also included, which is fitted between the clamping cylinder 1 and the half-cylinder 2. The intermediate sleeve 6 has a semi-spiral guide groove 61 on its side. One half-cylinder 2 has an elastic protrusion 26 on its side, which is integrally formed with the half-cylinder 2. The elastic protrusion 26 is positioned within the guide groove 61 and can move relative to the guide groove 61, allowing the intermediate sleeve 6 to extend or retract relative to the clamping cylinder 1. This structural design allows the intermediate sleeve 6 to extend or retract relative to the clamping cylinder 1 as needed, thereby meeting different usage requirements.

[0024] In some possible embodiments, the side of the clamp 1 is provided with an elastic inner protrusion 13, which is integrally formed with the clamp 1. The outer side of the intermediate sleeve 6 is provided with two positioning pin holes 62, and the elastic inner protrusion 13 can be inserted into the positioning pin holes 62. This structural design makes the connection between the intermediate sleeve 6 and the clamp 1 more stable, and also facilitates the positioning and assembly of the intermediate sleeve 6.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
