Abstract

The invention relates to a compound key ring which comprises a fixed ring and a moveable ring, wherein inlets are formed in both of the fixed ring and the moveable ring; blocking pins are arranged on the fixed ring; the quantity of the blocking pins is more than or equal to 2; bayonets are formed on the moveable ring in the positions corresponding to the blocking pins; and the fixed ring and the moveable ring are buckled through the bayonets. After a key hole is inserted into the fixed ring, the moveable ring is inserted into the key hole, and finally, the fixed ring and the moveable ring are buckled in the manner of pressing, so that a key can be easily inserted into the key ring. The key can be easily taken out through a reverse operation.

Description

technical field [0001] The invention relates to a common accessory, in particular to a composite key ring. Background technique [0002] The existing key rings have contradictions between firmness and ease of use. If the strength or elasticity of the key ring is too small, it is easy to deform. Otherwise, the diameter of the key ring will be large or it will be difficult to pry it open. It is difficult to penetrate when the key edge is large or the key hole is small. or take out. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a composite key ring that is easy to use. [0004] The technical solution adopted by the present invention is: a composite key ring, including a fixed ring and a movable ring, both of which have entrances, and bayonet pins are installed on the fixed ring, and the number of bayonet pins is ≥ 2, Bayonets are formed on the movable ring corresponding to the positions of the bayo...
