Shrinking refers to putting the pre-formed thermos cup body on a rotating rotating spindle mold, then pressing the thermos cup body against the rotating spindle mold through a head mechanism so that the thermos cup body rotates with the rotating spindle mold, and finally using a rotatable shrinking roller or shaping disk to press against the outer side of the thermos cup body to shrink the corresponding position of the thermos cup body. In the prior art, the shrinking wheel of the shrinking machine may cause the head mechanism to deviate when it rises, causing problems in the shrinking operation of the thermos cup body, thereby increasing the defective rate. Therefore, a head mechanism and a shrinking machine with a limit locking function are provided to solve the above problem. Utility Model Content
