Patent ID: 7963045

Claim:
A detection device for detecting whether a distance between centers of a first and a second through holes defined in a panel of an article meets determined specifications, the device comprising: a support member; a base member set on a first end of the support member, to enter the first through hole; and a measurement member set on a second end opposite to the first end of the support member, wherein a distance between a center of the base member and a center of the measurement member is substantially equal to a normal distance between centers of the first and second through holes, wherein the measurement member can enter the second through hole in response to an actual distance between the first and second through holes substantially equal to the normal distance; the measurement member cannot enter the second through hole in response to the actual distance between the first and second through holes being unequal to the normal distance; wherein two holes are defined in the support member, the base member and the measurement member respectively extend through the holes and slide in a direction perpendicular to the support member; wherein the measurement member comprises a main body, an extending body extending from a first end of the main body, and a securing portion formed around the first end of the main body, a groove is defined in a circumference of a second end opposite to the first end of the main body to engage with a fixing member, to prevent the measurement member from disengaging from the support member; the main body of the measurement member is cylinder-shaped, a diameter of the extending body of the measurement member is substantially equal to a diameter of the second through hole minus twice of a permissible error.
