Abstract
The utility model discloses a packing ring comprising a steel plate. The head end and the tail end of the steel plate are connected together and are provided with upward teeth and downward teeth matched with each other. The upward teeth and the downward teeth disposed on the head end and the tail end of the steel plate respectively are meshed mutually. A fixing sleeve is sleeved on the joint between the head end and the tail end of the steel plate. Wedges are stuffed between the fixing sleeve and the joint between the head end and the tail end of the steel plate. The packing ring is manufactured through rolling with flat steel; the head end and the tail end of the packing ring are provided with teeth which are matched with each other for preventing looseness; and the packing ring is specially used for tensioning fixation of tools and is characterized by reliability and stability.
