## Abstract

A flashlight tamper-proof structure for preventing a lamp cover fastened to an end of a flashlight from being unfastened manually is characterized in that: an appropriate section of an opening of a body of the flashlight forms a dented area having an internally threaded hole; an end of an opening of the lamp cover extends to form a carrying section, such that a connection element fits tightly inside the carrying section; an end of the connection element extends to form a rod section; a protruding portion having an inward-penetrating hole is formed at an end of the rod section, such that the protruding portion at the end of the rod section is positioned at the dented area on one side of the body; afterward, a screw is inserted into the hole at the end of the rod section and screwed to the internally threaded hole of the dented area.

## Claims

### Claim 1

A flashlight tamper-proof structure for preventing a lamp cover fastened to an end of a flashlight from being unfastened manually, characterized in that: a dented area having an internally threaded hole is defined in an appropriate section of a body of the flashlight, wherein the dented area is positioned proximate to an opening of the body; an end of an opening of the lamp cover extends to form a carrying section, such that a connection element is fitted tightly inside and engaged with an outer periphery of the carrying section; an end of the connection element extends to form a rod section; a protruding portion having an inward-penetrating hole is formed at an end of the rod section, such that the protruding portion at the end of the rod section of the connection element is positioned at the dented area on one side of the body; and a screw is inserted into the hole at the end of the rod section and screwed to the internally threaded hole of the dented area, thereby preventing the lamp cover fastened to an end of the flashlight from being unfastened manually.

### Claim 2 (depends on 1)

The flashlight tamper-proof structure of claim 1, wherein an outer diameter of the carrying section formed by extending the end of the opening of the lamp cover has to be slightly larger than an inner diameter of the connection element fitted inside the carrying section, such that the connection element and the carrying section at the end of the lamp cover are tightly positioned in place.

### Claim 3 (depends on 1)

The flashlight tamper-proof structure of claim 1, wherein, after removing the screw otherwise screwed to the rod section positioned at the dented area on one side of the body, the connection element tightly engaged with an end of the opening of the lamp cover is removed from the body together with the lamp cover to render it easy to change a power-supplying battery of the flashlight.
