Abstract:
    The utility model relates to a secondary lifting mechanism for internal stay of full-automatic oil hydraulic toe-lasting machine, including primary oil cylinder and corresponding primary lifting cylinder rod. Internal stay on the top realizes joint operation with primary lifting cylinder rod. Secondary oil cylinder and corresponding secondary lifting cylinder rod are available under the internal stay. The bottom of secondary lifting cylinder rod works jointly with primary lifting cylinder rod. Besides, its top interlinks with internal stay. The utility model firstly utilizes primary lifting cylinder rod to lift the internal stay to the designated place and reserves redundancy and then utilizes the secondary lifting cylinder rod to slightly go up and then enlarges, thus ensuring even tightness of upper textile, proper clamping force and no textile burst so as to improve shaping quality of front vamp and production efficiency.
