Claims

[Scope of utility model registration request]

A receiver having a base having a locking part on the outer surface and a collar formed at the upper end thereof, and an insertion hole that opens at least upwardly at the center of the base and the collar, and a receiver that is inserted into the insertion hole. A locking device comprising an insertion member, wherein the holder is provided with a slit passing through the center of the base, the collar portion is formed to be expandable and contractible, and the insertion hole of the holder is provided with a slit that passes through the center of the base. A fitting part with a smaller diameter than the upper part is formed in the lower part,
The insertion member is composed of a large diameter part formed at the upper part and a small diameter part formed at the lower part, and when the insertion member is inserted into the insertion hole, the small diameter part fits into the fitting part of the insertion hole. 2. A locking tool, characterized in that the large diameter portion fits into the upper part of the insertion hole, so that the upper part of the receiver expands substantially parallel to the lower part.
