When the adjustment rod 207 slides to the right end of the adjustment slot 303, the right end of the robot arm 302 will tilt upward to adjust the angle. Conversely, the electric push rod 205 pulls the adjustment rod 207 downward, and the right end of the robot arm 302 will move downward to adjust the angle. The angle of the robot arm 302 is adjusted to facilitate clamping or carrying of goods. An electric cylinder 208 is fixedly installed in the middle of the top of the support seat 2, and a mold block 3 is slidably installed at the upper end of the top of the support seat 2, and a through circular hole is opened at the right end of the mold block 3.
