Restriction device for preventing deformation of restriction plate of reel

Abstract

A restriction device for preventing deformation of restriction plate of reel is disclosed. The restriction device includes a first circular restrictor, a second circular restrictor, a block member and a first push member. A clamping space exists between the first and second circular restrictors mounted on a shaft and is configured to accommodate a reel mounted on the shaft. The second circular restrictor is able to be moved on the shaft in an axial direction, the block member is fixed on the shaft and the first push member is placed between the block member and the second circular restrictor. The first push member is configured to apply a force to push the second circular restrictor toward the first circular restrictor to press a first restriction plate of the reel such that the deformation of the first restriction plate is prevented.
