[0058] Working process or working principle:

[0059] Step 1: Adjust the handle to adjust the size of the large glass to be cut and correspond to the scale on the base support 54.

[0060] Step 2: Move the large glass between the cutting frame 7 and the breaking frame 6 under the hoisting equipment. At this time, the large glass is directly cut and broken during the hoisting process.

[0061] Step 3: The clamping cylinder 63 acts, and the slide plate I 62 drives the clamping block to clamp the large glass.

[0063] Step 5: The tool rest seat 2 moves driven by the transmission lead screw 11. The tool rest on the tool rest seat 2 is pushed by the tool rest cylinder 21, and the tool head adheres to the surface of the large glass. The pressing piece I and the pressing piece II play a protective role for the large glass.

[0064] Step 6: The transmission lead screw 11 drives the tool rest seat 2 and the tool rest and the tool head thereon to move on the surface of the large glass, from bottom to top or from top to bottom.

[0065] Step 7: After cutting is completed, the breaking cylinder II 43 acts to drive the double parallel crank mechanism 42 to change the angle. At this time, the large glass is broken.

[0066] In Steps 6 and 7, the negative pressure suction pipeline 8 is opened, and the glass debris is sucked out.

[0067] When the tool head and tool holder cylinder 31 needs to be replaced, the connecting plate 32 drives the ratchet pawl II 37 to push the ratchet 35 forward, and the ratchet 35 drives the tool handle 33 to rotate to replace the tool head.
