Anti-theft cat eye device

Abstract

The invention discloses an anti-theft cat eye device. A connecting structure comprises multiple circles of first reverse teeth, multiple circles of second reverse teeth, at least one open groove and a hoop sleeve, wherein the first reverse teeth are formed at the end of the insertion end of a hollow inner side pipe or a hollow outer side pipe, the second reverse teeth are formed at the end of the insertion end of the hollow outer side pipe or the hollow inner side pipe and are suitable for being meshed with the first reverse teeth and being reversely buckled together with the first reverse teeth, the open grooves are axially formed in the side wall of the insertion end of the hollow inner side pipe or the hollow outer side pipe so that the first reverse teeth and the second reverse teeth can be conveniently matched, the hoop sleeve is arranged on the hollow inner side pipe provided with the open grooves or the hollow outer side pipe provided with the open grooves in a sleeved mode, and the hoop sleeve is moved towards the open grooves when pushed by an installation tool so as to tightly hoop pipe openings of the open grooves. Due to the arrangement of the connecting structure, the anti-theft cat eye device is easy to assemble, and matching between the hollow inner side pipe and the hollow outer side pipe can be adjusted before locking is conducted.

Description

technical field [0001] The invention relates to a cat's eye device, in particular to an anti-theft cat's eye device with anti-theft function. Background technique [0002] Cat's eye, also known as door mirror, is a small optical instrument installed on the door of a residential house, which is convenient for residents to observe the outdoor situation.
