In the initial state, the glass substrate placement platform 205 moves upward relative to the glass substrate placement base 101 due to the pushing of the pushing spring 204. The seat sleeve outer gear ring 107 rotates counterclockwise by driving the convex slide rod 106 and the spiral guide rail groove 202. At this time, a structure for releasing the clamping and approaching of the glass substrate packaged product 500 is formed between the first glass substrate clamping arm assembly 300 and the second glass substrate clamping arm assembly 400. Protective rubber pads are provided on the top surface of the glass substrate placement platform 205 and the inner surface of the auxiliary clamping arm 306. When the glass substrate packaged product 500 is clamped and approached between the first glass substrate clamping arm assembly 300 and the second glass substrate clamping arm assembly 400, the driving gear 309 moves on the edge gear plate 109.

Through the gearing cooperation between the seat sleeve outer gear ring 107 and the gear arm 302, At this time, a structure for clamping the finished glass substrate package 500 is formed between the first glass substrate clamping arm assembly 300 and the second glass substrate clamping arm assembly 400. Through this mechanism, the glass substrate packaged product 500 can be supported, placed and clamped by its own weight. This placement rack is convenient and reliable to use. At the same time, the U-shaped slide table 303 slides back and forth in the end limit groove 102, and the driving gear 309 is engaged with the edge gear plate 109. The first glass substrate clamping arm assembly 300 and the second glass substrate clamping arm assembly 400 form a structure for clamping the finished glass substrate package 500. When the glass substrate packaged product 500 is in the clamping and closing structure, the driving gear 309 moves on the edge gear plate 109. At this time, the internal threaded seat blocks 304 at both ends of the bidirectional threaded screw 308 move closer to each other. At this time, the extension arm 305 is extended, and multiple auxiliary clamping arms 306 are set at multiple central axis points of the extension arm 305. Through the extension and retraction of the extension arm 305, the multiple auxiliary clamping arms 306 form a telescopic side clamping arm structure for the glass substrate packaged product 500. Through this extension clamping structure, the clamping and limiting requirements of the side of the glass substrate packaged product 500 of different heights are met.
