[0002] In the field of modern industrial production and mechanical equipment maintenance, sockets are a common tool accessory that is widely used in the tightening and removal of screws and nuts. Traditional socket designs often have a single function, focusing mainly on providing an interface that adapts to hand tools (such as wrenches and pneumatic tools) to rotate the workpiece, while not enough consideration is given to the installation, clamping, and quick release of the workpiece. As a result, in actual operations, workers often need to use additional tools or place and remove workpieces by hand, which is not only inefficient, but may also cause damage to the workpiece or personal injury due to improper operation.

[0003] Therefore, in order to solve the problem of cumbersome manual work, automation improvements have been made in the prior art. For example, the invention patent with publication number CN112975802A discloses a sleeve, which includes: a main rod, an outer sleeve and an ejection mechanism. The outer sleeve is movably sleeved on the main rod, and the ejection mechanism is arranged inside the main rod. The ejection mechanism includes an elastic member and a push member, and the elastic member drives the push member to push against a first object. However, its design is cumbersome and the structure is complex, which reduces the work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings.

[0023] Embodiment 1

[0024] like Figure 1 and Figure 2 As shown, this embodiment provides a multifunctional sleeve, including a sleeve body 4, the sleeve body 4 is hollowed out to form a hollow channel, a mounting portion 41 and a clamping portion 42 are respectively provided at both ends of the hollow channel, a pushing portion 43 is provided between the mounting portion 41 and the clamping portion 42, the pushing portion 43 includes a pushing rod 431 arranged toward the clamping portion 42, and the pushing rod 431 moves toward the clamping portion 42 to push the workpiece in the clamping portion 42 out.

[0025] By arranging the ejection portion 43 and the ejection rod 431 between the mounting portion 41 and the clamping portion 42 of the sleeve body 4, the workpiece can be quickly and conveniently ejected. The structure is simple, the production cost is low, the work efficiency is improved, and at the same time, the damage that may be caused by manual removal of the workpiece is avoided, thereby enhancing the convenience and safety of use.

[0026] Furthermore, chamfers are provided at both ends of the hollow channel to facilitate installation and guidance.

[0027] Preferably, the cross section of the hollow channel at the mounting portion 41 is rectangular, and a slot 411 is provided on the side wall of the hollow channel of the mounting portion 41. The cross section of the hollow channel is designed to be rectangular, and the slot 411 is added to the side wall of the mounting portion 41, so that it can be fixed more stably with a square or rectangular tightening rod or other parts to prevent rotation or sliding, thereby improving the stability and applicability of the workpiece installation.

[0028] Preferably, the ejection portion 43 further includes an ejection reset spring 432 disposed between the ejection rod 431 and the sleeve body 4. By adding the ejection reset spring 432 between the ejection rod 431 and the sleeve body 4, it is not only ensured that the ejection rod 431 can automatically reset after ejecting the workpiece, reducing the operation steps, but also extending the service life of the ejection mechanism, thereby improving the automation level and durability of the overall device.

[0029] A mounting step is formed between the hollow channel of the push-out portion 43 and the hollow channel of the clamping portion 42, and a first hollow-core permanent magnet 433 is fixedly mounted on the mounting step, and the push-out rod 431 is slidably inserted into the hollow core of the first hollow-core permanent magnet 433. By fixing the first hollow-core permanent magnet 433 on the mounting step and sliding the push-out rod 431 therein, not only is the push-out rod 431 able to slide smoothly, but also the attraction of the magnet is used to enhance the fixing effect of the installation to other components, thereby improving the stability of the clamping and the flexibility of the operation.

[0030] The portion of the ejection rod 431 that is not inserted into the first hollow-core permanent magnet 433 extends radially to form a limit platform 4311, and a push-out reset spring 432 is installed on one side of the limit platform 4311, and the other side is arranged against the first hollow-core permanent magnet 433. The design of the limit platform 4311 effectively limits the motion range of the ejection rod 431, ensuring the precise control of the ejection action; at the same time, the use of the first hollow-core permanent magnet 433 further optimizes the reset mechanism of the ejection rod 431, making the entire ejection process smoother and more reliable.

[0031] Furthermore, a second hollow permanent magnet 434 is fixedly mounted on one side of the hollow channel of the clamping portion 42 facing the pushing portion 43 , and an end surface of the second hollow permanent magnet 434 and a side wall of the hollow channel together form a clamping cavity of the clamping portion 42 .

[0032] At least one adsorption magnetic column 421 is disposed on the outer end surface of the clamping portion 42. Preferably, four adsorption magnetic columns 421 are evenly disposed on the outer end surface of the clamping portion 42 along the central axis of the sleeve body 4.

[0033] At least one adsorption magnetic column 421 is arranged on the outer end face, which expands the adaptability of the multifunctional sleeve to different types of workpieces, especially for small or thin workpieces that require additional magnetic suction to assist in fixing, significantly improving the working efficiency and flexibility. Evenly arranging four or more adsorption magnetic columns 421 not only balances the distribution of adsorption force on the workpiece, ensuring the uniformity and stability of clamping, but also improves the workpiece holding capacity during multi-directional operation, which is suitable for precise operation requirements in complex working environments.

[0034] The utility model also provides a sleeve changer, which is used to load and unload the multifunctional sleeve as described above. The sleeve body 4 of the multifunctional sleeve is a cylinder, and the middle section of the outer cylindrical surface of the sleeve body 4 is recessed toward one side of the axis of the sleeve body 4 to form an annular groove.

[0035] Preferably, the sleeve changer includes a U-shaped seat 9, which is arranged horizontally, and a limit opening 91 is opened on the top surface of the U-shaped seat 9, and the limit opening 91 is larger than the diameter of the annular groove and smaller than the diameter of the sleeve body 4, and a positioning pin 92 is arranged on the bottom surface of the U-shaped seat 9 corresponding to the limit opening 91, and a position sensor 93 is arranged on the side surface of the U-shaped seat 9 corresponding to the position between the limit opening 91 and the positioning pin 92.

[0036] The U-shaped seat 9 is equipped with a limit opening 91, a positioning pin 92 and a position sensor 93, which not only accurately locates the position of the multifunctional sleeve, ensuring the accuracy of the replacement process, but also improves the safety and intelligence level of the operation through electronic monitoring, making the sleeve replacement process more automated and efficient.
