[0044] In the embodiment, the support 4 is provided with an annular groove, and the mouse shell is provided with a support corresponding to the annular groove, which is not shown in the figure. The support 4 can be swung by rotating the shaft sleeve 10 around the connection between the support and the annular groove through an external force. Thus, the left swing key 20 or the right swing key 21 can be pressed by the pressing portion 22 at the bottom, the support 4 can move downward, the middle key 2 can be pressed, and the functions of the mouse can be diversified, so that the mouse can be applied to different fields.

[0045] Specifically, the light sensing component includes an optical receiver 23 and an optical transmitter 24, both of which are arranged in the support 4. The surface of the magnetic outer shaft 8 is uniformly provided with light transmission holes 25.

[0046] In the embodiment, the optical transmitter 24 transmits an optical signal, which can be received by the optical receiver 23. The optical signal can be received by the optical receiver 23 only when it passes through the light transmission holes 25 on the magnetic outer shaft 8. The rotation of the shaft sleeve 10 can be determined by detecting the intermittent optical signal, so that the effect of flipping a webpage can be achieved.

[0047] In use, the finger touches the rubber roller 16 on the shaft sleeve 10, and the shaft sleeve 10 rotates through the friction between the finger and the rubber roller 16. Since the shaft sleeve 10 is connected to the magnetic outer shaft 8 through the limiting rubber ring 15, and the metal shaft 5 and the magnetic inner shaft 6 are integrally molded, the shaft sleeve 10 will drive the magnetic outer shaft 8 to rotate synchronously. The light transmission holes 25 on the magnetic outer shaft 8 rotate with the magnetic outer shaft 8. The optical transmitter 24 in the light sensing component emits an optical signal, which can be transmitted to the optical receiver 23 through the light transmission holes 25.

One optical signal is transmitted for each degree, 24 signals are transmitted for each rotation, the webpage can be flipped, the light transmission holes 25 are provided with 12 holes, and the light transmission holes 25 can rotate through the rotation of the magnetic outer shaft 8.

[0048] The magnetic inner shaft 6 and the magnetic outer shaft 8 are both magnetic, the first magnetic teeth 7 on the magnetic inner shaft 6 protrude towards the magnetic outer shaft 8, the second magnetic teeth 9 on the inner wall of the magnetic outer shaft 8 protrude towards the magnetic inner shaft 6, the first magnetic teeth 7 and the second magnetic teeth 9 are both uniformly arranged, one-to-one correspondence in the natural state, in the process of rotating the magnetic outer shaft 8 by the shaft sleeve 10, when the first magnetic teeth 7 correspond to the second magnetic teeth 9, the attraction between them is the strongest, as the first magnetic teeth 7 and the second magnetic teeth 9 are misaligned, the attraction gradually weakens, and then the attraction strengthens again, so that a paragraph feeling can be generated during use, the first magnetic teeth 7 and the second magnetic teeth 9 are both arranged as 24, one rotation is 24, and each paragraph has a paragraph feeling, one rotation corresponds to an optical signal, one rotation sends 24 signals, and the reaction to the computer is the page turning function of the mouse wheel;

[0049] When the shaft sleeve 10 is rapidly rotated by force, the external force will overcome the attraction between the first magnetic teeth 7 and the second magnetic teeth 9, and under the action of inertia, the shaft sleeve 10 will continue to rotate, and the attraction between the first magnetic teeth 7 and the second magnetic teeth 9 will assist the shaft sleeve 10 to continue to rotate after losing the external force, so that the shaft sleeve 10 drives the magnetic outer shaft 8 to continuously rotate, and the extremely fast function can be realized, which is convenient for quickly browsing web pages, and finally the magnetic outer shaft 8 stops rotating under the action of resistance and the attraction between the first magnetic teeth 7 and the second magnetic teeth 9, and the first magnetic teeth 7 and the second magnetic teeth 9 correspond one-to-one;

[0050] The support 4 is provided with an annular groove, and the mouse shell is provided with a support part corresponding to the annular groove, which is not shown in the figure, and the shaft sleeve 10 is rotated around the connection between the support part and the annular groove by external force, so that the swing of the support 4 can be realized, so that the left swing key 20 or the right swing key 21 can be squeezed by the upper pressing part 22, the support 4 can be moved downward, the squeezing of the center key 2 can be realized, and the multi-function can be realized, so that the function of the mouse is more, and it is convenient to be applied to different scenes.

[0051] In summary, the magnetic damping extremely fast optical wheel solves the problem that the mechanical encoder is too mechanical and not smooth enough to affect the hand feeling by arranging the pressing part 22 and the shaft sleeve 10.
