In the initial state, the lever 313 does not act on the rotating member 311, but the elastic member 314 downwardly presses the rotating member 311, so that the rotating member 311 drives the locking rod 312 to approach the tooth portion 20, and the locking rod 312 resists against the tooth portion 20, at this time, the sliding roller 22 has sound and hand feeling, enters a general roller mode, and can perform the original function of the sliding roller 22.

When the switch member 32 is pressed downward to drive the end portion of the lever member 313 abutting against the switch member 32 to swing downward, so that the lever member 313 rotates, the end portion of the lever member 313 extending to the rotating member 311 tilts upward to drive the rotating member 311 to rotate counterclockwise, the rotating member 311 drives the locking lever 312 to leave the tooth portion 20, the locking lever 312 is separated from the resistance to the tooth portion 20, and meanwhile, the elastic member 314 elastically deforms, so that the sliding roller 22 is silent, and is converted into a shuttle flying roller mode, and a page (picture) can be rapidly scrolled when the sliding roller 22 is slid.

When the switch element 32 is pressed down again, the switch element 32 moves up to reset, which drives the two ends of the lever element 313 to reset, and under the elastic restoring force of the elastic element 314, the switch element acts on the rotating element 311 again to drive the rotating element 311 to rotate clockwise, so that the rotating element 311 drives the locking rod 312 to approach the direction of the tooth-shaped portion 20, the locking rod 312 resists the tooth-shaped portion 20, and at this time, the normal roller mode is entered again.

It can be seen from the above that, the swing of the lever member 313 is controlled by the switch member 32, the swing of the lever member 313 drives the rotation member 311 to rotate, so as to drive the clamping rod 312 to switch between being close to the tooth portion 20 and being far away from the tooth portion 20, thereby realizing the free switching of the mouse between the general roller mode and the shuttle roller mode, satisfying different operation requirements of the user, and because the roller is not pressed during the operation, therefore, the realization of the original function of the roller pressing can not be influenced, being beneficial to expanding the functional application range of the mouse, and improving the operation and control convenience.
