Specifically, the connecting sleeve 11 of the present embodiment is a cylindrical structure with an opening at one end and a through hole at the other end, and the opening diameter of the connecting sleeve 11 is slightly larger than the outer diameter of the fixing portion 53, so that the fixing portion 53 of the rotating shaft 51 is inserted from the opening of the connecting sleeve 11 and is fixed in the connecting sleeve 11 in a limited manner; in addition, a first screw hole is axially formed at the fixing portion 53 corresponding to the through hole of the connection sleeve 11 so that a screw rod passes through the through hole of the connection sleeve 11 and is screwed into the first screw hole of the fixing portion 53, and the fixing portion 53 of the rotation shaft 51 is detachably mounted in the connection sleeve 11 of the connection arm 10 by the screw rod.

In this way, the upward force of the compression spring 57 can be used to freely rise when the rotary ram 56 needs to be adjusted upward. Further, a plurality of limiting pins 58 may be disposed on the limiting portion 54 in parallel along the axial direction of the rotating shaft 51, and correspondingly, a limiting insertion hole for inserting the limiting pins 58 is disposed at the end of the rotating press head 56 with smaller outer diameter along the axial direction thereof.

In other words, by providing the first limiting step 13 on the connection sleeve 11, the rotation range of the rotation sleeve 21 can be limited, and the rotation range of the rotation sleeve 21 is prevented from being too large to be easily impacted on other devices. The shapes of the first limiting step 13 and the second limiting step 24 may be arc-shaped structures, and the arc length of the first limiting step 13 and the arc length of the second limiting step 24 may be set according to actual limiting angles.
