Abstract: A computer mouse is provided and has a mouse main body, a rubber cover and a foot pad. The mouse main body has engagement holes. The rubber cover is covered on the mouse main body and formed with an opening. The foot pad has a flat foot-pad main body which has engagement members, each of which has a connection portion. The connection portion has a first end connected to the engagement member and having a height matched with that of the engagement hole, and a second end protruded to form an umbrella-like engagement portion. When installing the computer mouse, the connection portion passes through the opening and is then received in the engagement hole, and the engagement portion is engaged against an inner edge of the engagement hole, so that the foot pad is firmly mounted on the computer mouse. Thus, the computer mouse has simpler installation and aesthetic appearance.

Abstract: A key structure of a keyboard includes a cap having a cover and a key post protruded under the cover, a key base which has a base board, restraining posts and a guiding post protruded on the base board with being arranged and spaced to surround a receiving space thereamong, and a resilient dome with a recessed passageway mounted between the cover and the base board to receive the key post and the posts in the passageway. The key post includes a base pillar and guiding ribs arranged around the base pillar. A guiding channel is opened in an inside of the guiding post to communicate with the receiving space and passes through a top of the guiding post. The key post is movably inserted in the receiving space with one guiding rib being slidably inserted in the guiding channel and the other guiding ribs being resisted against the respective restraining posts.

Abstract: A computer mouse is provided, and has a mouse main body, a rubber cover and a foot pad. The mouse main body has at least one engagement hole. The rubber cover is covered on an outer side of the mouse main body and formed with at least one opening corresponding to the engagement hole. The foot pad has a flat foot-pad main body which has at least one engagement member. The engagement member has an elastic arm and an engagement fastener protruded from a distal end of the elastic arm. The engagement member passes through the opening, and then engaged and received in the engagement hole. When installing the computer mouse, the engagement fastener can be engaged and received in the engagement hole, so that the foot pad is firmly mounted on the computer mouse. Thus, the computer mouse has simpler installation and aesthetic appearance.

Abstract: Disclosed is a bendable mouse, comprising an operating portion, a bendable portion and a rubber body. The bendable portion comprises a base and a bendable body. The base is fixed to the operating portion. The base comprises a base plate and an attached body. The base plate is jointed with the bendable body. The attached body is fixed with the base plate. A fixing block is positioned at the attached body. The rubber body covers the bendable portion and comprises a base joint sleeve and bendable sleeve. An inserter is formed at the bendable sleeve toward the inside of the base joint sleeve and inseparably adheres with the fixing block. The bendable mouse can prevent the separation phenomenon of the rubber body from the base and ensures the rubber body to remain adhering closely with the bendable portion when it changes from the curved status to the straight status.

Abstract: A key structure has a fixing base. The fixing base includes a fixing board, and a plurality of platforms extending upwards from a top of the fixing board and spaced away from each other. Each of the platforms is formed with a restraining hole at a top thereof. A resilient assembly adhered onto the fixing board has a resilient portion which is placed among the platforms. A key cap is resiliently supported by the resilient portion to suspend above the fixing base, and has a plurality of guiding rods extending downwards from a bottom thereof and movably inserted into the corresponding restraining holes for guiding the key cap to move upwards and downwards with respect to the fixing base.
