At the same time, the trigger lever 18 projects into the interior of the slide groove 19. When the trigger section 181 touches the outer cover 211, the trigger section 181 drives the outer cover 211 to move towards the outer side of the spacing post 6, so that the adduction spring 24 is stretched. When the inclined surface 26 of the inner core 212 contacts with the guiding inclined surface inside the clamping block, the telescopic rod 21 and the limiting column 6 can rotate counterclockwise under the action of the outer pushing spring 213, so that the inner core 212 can be inserted into the key slot of the clamping block to limit the circumferential rotation between the limiting column 6 and the clamping block.
After the template is moved to the designated position, the control electromagnet 14 is powered off, and the ceramic spring 15 drives the movable sleeve 11 away from the clamping block through elastic force. In the process, the triggering section 181 is gradually close to the clamping claw 5922, and the telescopic rod 21 is gradually retracted into the limiting column 6 under the action of the inward-retracted spring 24, so that the inner core 212 is removed from the key groove of the clamping block.
The above are only typical examples of the present invention, and besides, the present invention may have other embodiments, and all the technical solutions formed by equivalent substitutions or equivalent changes are within the scope of the present invention as claimed.
