## Background
FIELD OF THE INVENTION
The present invention relates to a computer mouse, and more particularly to a bendable computer mouse.
BACKGROUND OF THE INVENTION
Traditionally, when a computer mouse is used to move on an object (such as a desk top, a mouse pad and etc.), the friction is inevitably and continuously generated between the computer mouse and the object. For increasing the abrasion resistance of a traditional computer mouse, at least one foot pad is generally attached to a bottom end surface of the computer mouse by adhesive or screw-connected thereto by screws.
However, the foot pad of the traditional computer mouse is installed by adhesive or screws, so that the installation is relatively complicated and has no aesthetic appearance.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide a computer mouse, which has simpler installation and aesthetic appearance and thus can overcome the disadvantages existing in the conventional technologies, as described above.
To achieve the above object, a computer mouse of the present invention comprises a mouse main body, a rubber cover and a foot pad. One end of the computer mouse is provided and has a mouse main body, a rubber cover and a foot pad. The mouse main body has one end formed with at least one engagement hole. The rubber cover is covered on an outer side of the mouse main body and has one end formed with at least one opening. The foot pad has a flat foot-pad main body which has one end formed with at least one engagement member. The engagement member 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 toward two lateral sides to form an umbrella-like engagement portion. The connection portion of the engagement member can pass through the opening of the rubber cover and then be received in the engagement hole. Meanwhile, the engagement portion is engaged against an inner edge of the engagement hole.
As described above, when installing the computer mouse, the connection portion of the engagement member of the foot pad passes through the opening of the rubber cover and then received in the engagement hole. The first end of the connection portion connected to the engagement member has the height matched with that of the engagement hole, so as to ensure to install the foot pad on the computer mouse without shifting upward or downward. The umbrella-like engagement portion of the engagement member is engaged against the inner edge of the engagement hole. Thus, the foot pad is firmly mounted on an outer side of the computer mouse, so that the computer mouse has simpler installation and aesthetic appearance.
