Claims

[Claims for Utility Model Registration] An ear holder base having an arm provided on a link plate and extending downward and forward and having a pin seat attached to the upper surface of its front end; Supported so that it can swing freely,
In addition, it is composed of a slip-off prevention device having a presser head on the upper part that prevents the sheet-like material held by the pin sheet from coming off the pin, and when the presser head is moved from the presser position to the rearmost position. In an ear holder for a pin tenter that takes the pin tenter to the open position, when the presser head comes to the holding position forward of the pivot center of the ear drop prevention device, it is urged toward the pin seat and moved to the open position. A presser head biasing member that biases the presser head backward is disposed, and its front end is swingably supported by the arm and its rear end is swingably supported by the ear drop prevention device. is composed of a plate body whose front end is swingably supported by the arm and the rear end by the ear drop prevention device, respectively, and a coiled push spring fitted and covered by the plate body; The shaft supporting the rear end of the ear drop prevention device rotates around the pivot shaft as the ear drop prevention device swings, and when the presser head comes to the presser position, the center of the pivot and the plate body rotate. be below the straight line connecting the front end of the plate with the center of the shaft that supports it, and be above the straight line when the presser head is in the open position, and have a notch on one of the front and rear ends of the plate. The shaft that supports the end of the plate on the side where the notch is formed is fitted into the notch, and the shaft that supports the other of the front and rear ends of the plate is fitted into the plate. A stopper for preventing the spring receiver from escaping is provided at the end of the plate body on the side where the notch is formed, and a part of the plate body that is closer to the stopper for preventing the spring receiver from escaping than the push spring. An ear holder for a pin tenter, wherein the spring receiver is slidably and loosely fitted over the plate.
