NOVELTY - The invention claims a chromatography silica gel plate, comprising a mounting seat seat and an adjusting mechanism, a screw rod, a connecting rod, a pressing plate, hard silicon rubber plate, a wearable layer, graphene radiating layer and a high temperature resistant layer, wherein the adjusting mechanism a U type placing frame. in order to improve the stability of the silica gel plate, when using the silica gel plate, according to the width of the silica gel plate, adjusting the position of the U type placing frame, rotating the screw thread rod the screw thread rod the U type placing frame lapped on the other side to be close to each other, U type placing frame drives the fixed rod movement connected with it, at the same time, stretching the first spring fixedly connected with it, then the clip-shaped handle drives the pressing plate fixedly connected with it to move upwards through the connecting rod, the extruding plate presses the second spring fixedly connected with it, the second spring is stressed and contracted, then the silica gel plate is placed in the U type placing frame, the second spring resets to drive the extruding plate to extrude on the hard part of the silicon rubber plate, which greatly improves the stability.
