The structural design of the cam 416 can avoid the direct contact between the bottom surface of the lower tool apron 41 and the upper surface of the middle carriage 2, but the contact between the lower tool apron 41 and the upper surface of the middle carriage 2 through the cam 416 reduces friction, prolongs the service life, and ensures the smoothness of the sliding of the lower tool apron 41 on the middle carriage 2.
The remainder is the same as in example 1 or 2.
While the invention has been described in detail in terms of general description and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made or some functional modules can be deleted based on the invention. Accordingly, such modifications or improvements or omissions may be made without departing from the spirit of the inventions.
