## 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 end of an opening of a body of the flashlight extends to form a carrying portion; an internal thread section penetrates a front end of the carrying portion; a hole is formed at a corresponding point of a rear end of the carrying portion, to allow a screw to be inserted into the carrying portion, such that the screw is screwed to the internal thread section with a tool; concave indentations are formed at the periphery of the opening of the lamp cover fastened to the end of the opening of the body of the flashlight; and the screw screwed to the internal thread section is moved forward with the tool to reach the concave indentations.

## 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: an appropriate section of an end of an opening of a body of the flashlight extends to form a carrying portion; an internal thread section penetrates a front end of the carrying portion; a hole is formed at a corresponding point of a rear end of the carrying portion, to allow a screw to be inserted into the carrying portion, such that the screw is screwed to the internal thread section of the front end with a tool; a plurality of concave indentations is formed at a periphery of an opening of the lamp cover fastened to the end of the opening of the body of the flashlight, such that the screw screwed to the front end of the carrying portion on one side of the body of the flashlight can be moved forward with the tool to reach the concave indentations at the periphery of the lamp cover, and thus the lamp cover fastened to an end of the flashlight cannot be unfastened manually.

### Claim 2 (depends on 1)

The flashlight tamper-proof structure of claim 1, wherein the internal thread section penetrating the front end of the carrying portion formed by extending the appropriate section of the end of the opening of the body of the flashlight can be implemented by a nut embedded at the front end of the carrying portion.

### Claim 3 (depends on 1)

The flashlight tamper-proof structure of claim 1, wherein the carrying portion formed by extending the appropriate section of the end of the opening of the body of the flashlight forms a channel-shaped container opening at the top thereof to allow the screw screwed to the internal thread section at the front end of the carrying portion to fall into between the carrying portion after the screw has been unfastened, such that the screw can be conveniently screwed again at any time and moved forward to reach the concave indentations at the end of the lamp cover.

### Claim 4 (depends on 1)

The flashlight tamper-proof structure of claim 1, wherein the diameter of the hole at the rear end of the carrying portion formed by extending the appropriate section of the end of the opening of the body of the flashlight permits admission of an end of the tool for use in fastening the screw.
