When the placement plate 501 rotates ninety degrees, the plug-in rod 401 is released again. The elastic force of the spring 402 acts on the side wall of the baffle 403 to improve the stability of the plug-in rod 401 inserted into the hole groove 2 503 and the hole groove 1 305, thereby limiting the rotation of the support component 2 5 and improving the quality of liquid crystal film shearing.
