In the top of the main body is provided with an upper room for the elastic article and the stopping button and an operating block to be placed in. The lower section of the operating block is placed in the hollow of the stopping button, and a fixing pin is used to penetrate through the passing holes of the main body and the long hole of the operating block so as to make the operating block be pivotally assembled with the main body. The operating block can be operated by one finger to make the stopping button be withdrawn inward for the pressing board to be moved by another finger at the same time so as for the pressing board and the main body as well as the supporting skeleton being shifted together to choose one of the ratchets on the two planks provided in the bottom of the upper plate for the catch portion to catch and fix.
