Bolt, and caging bolt screw lifting contiguous block on；After then so setting, the angle of big gun head can be adjusted at any time by connection sheet,
So that the blow mold of different angles can be used in big gun head, the scope of application is wider, so as to reduce use cost.
Preferably, instruction block of the exposed end of the rotating shaft provided with wedge shape, connecting hole is attached in the connection sheet
Near be provided with can show the scale of rotational angle, and indicate that the tip of block faces scale；After then so setting so that user can
Accurately to adjust big gun brilliance degree, the angle when forward gun head also can be intuitively observed, the user's that is more convenient for using and operating.
Preferably, being located at auxiliary stopper block on the lifting contiguous block, the auxiliary stopper block is provided with auxiliary stopper
Bolt, the auxiliary stopper bolt upper end is supported with connection sheet closes spacing, and auxiliary stopper bolt and supporting for connection sheet close position position
At the position rotated between connecting hole and arcuate socket；After then so setting, the stability of connection sheet in use is more preferable,
Also the stability and accuracy of big gun head when in use are ensured that, so as to can further improve yield rate.
Preferably, the second cylinder is provided with baffle plate on the hoistable platform, and baffle plate is angularly disposed, the baffle plate is near
One end of taut material bar is provided with the indent of " U " font, and when taut material bar is in vertical state, the material bar that stretches tight is located in indent；Then so
After setting so that blank and other foreign objects are difficult to have influence on the normal work of taut material bar and the second cylinder, it is ensured that taut material bar and the
Two cylinder stability in uses and reliability, so as to extend the service life of taut material bar and the second cylinder.
Preferably, first cylinder is located on the position between slide unit and swash plate；After so setting, overall structure is tight
Preferably, space-consuming is smaller for gathering property, and slide unit also acts the effect of the first cylinder of protection, so as to ensure the stability in use of mechanism
And reliability.
Preferably, the angle between the extension block and vertical line is 0.5 °~3.5 °；Then in this angular range, stretch tight
During material, the situation for getting stuck or splitting blank is less prone to, it is ensured that stability and reliability during taut material.
