Abstract

A mouse including a top cover which has press keys for signal input into the computer, a coupling device at the bottom, a downward rod with a center axle hole, and a plurality of locating posts; a circuit board which has an operation circuit and an IC, a plurality of switches corresponding to the press keys of the top cover shell, and a plurality of locating holes respectively connected to the locating posts of the top cover shell by a respective screw; a case-like intermediate shell which has an opening through which the downward rod of the top cover shell pass, a plurality of hook holes near the rear side, and a plurality of screw holes respectively fixed to the coupling device of the top cover shell by screws; and a bottom shell fitting over the intermediate shell at the bottom which has an upright index rod inserted through the opening of the intermediate shell and fitted into the center axle hole of the downward rod of the top cover shell and having a cable connected to the IC of the circuit board, and a plurality of upright hooks respectively hooked in the hook holes of the intermediate shell.

Claims

1. A mouse comprising:

a top cover shell having a plurality of pivoted press keys at a front side thereof adapted for triggering a respective contact on a circuit board, a coupling device at a bottom side thereof, a downward rod defining a center axle hole, and a plurality of locating posts raised from the bottom side;

a circuit board adapted for connecting to a computer system by a cable thereof for controlling the movement of the cursor, having an operation circuit and an integrated circuit, a plurality of switches corresponding to the press keys of said top cover shell, and a plurality of locating holes respectively connected to the locating posts of said top cover shell by a respective screw;

a case-like intermediate shell having, an opening in the middle, which receives the downward rod of said top cover shell, a plurality of hook holes near a rear side thereof, and a plurality of screw holes respectively fixed to the coupling device of said top cover shell by screws; and

a bottom shell fitting over said intermediate shell at one side opposite to said top cover shell, having an upright index rod inserted through the opening of said intermediate shell and fitted into the center axle hole of the downward rod of said top cover shell and having a cable connected to the integrated circuit of said circuit board, and a plurality of upright hooks respectively hooked in the hook holes of said intermediate shell.

2. The mouse of claim 1 wherein said intermediate shell has a wire hole at a front side thereof for the passing of the cable of said circuit board.
