ABSTRACT:
A membrane packing dispenser includes a rotary shaft sleeve and a holding sleeve. The cylindrical portion of the rotary shaft sleeve is step-shaped and formed with a lower portion to be fitted with a membrane reel and an upper portion for receiving the cylindrical portion of the holding sleeve. The lower portion of the rotary shaft sleeve has its outer wall bored with plural slots respectively disposed therein with a tightening plate having its upper opposite sides respectively fixed with an engage projection. Thus, the lower portion of the rotary shaft sleeve can be firmly engaged with the end of a membrane reel by the engage projections of the tightening plates. The engage projections can be elastically adjusted to shift; therefore, the rotary shaft sleeves are applicable to various membrane reels with a little difference in size.
