碟形彈簧, 內(nèi)部滾輪以及卡輪的組合, 能使模具的開合具有良好的平衡性。 滾輪的旋轉(zhuǎn)能較好的防止偏心磨損的發(fā)生。 鎖緊套爲(wèi)上下對稱式, 所以若有磨損也可倒置安裝以再次使用 。 因爲(wèi)鎖緊座的背面有避空位, 所以模板上有臺階時也可以使用。
       Disc spring, and a combination of internal roller card wheel, can make the opening and          closing of the mould has good balance. Wheel rotation can better prevent eccentric wear occurs.          The locking sleeve is symmetric, so if the wear can also be installed to use again. Because the back of          the locking seat is avoiding vacancy, can also use so the template has the steps.
