Abstract
The present invention provides a polarizing sheet removing tool and removing method. The tool includes a handle and a blade mounted on the handle. The handle includes a main body, a piston device mounted on the main body, and a guide tube mounted on the main body. The main body forms therein a channel for containing an adhesive dissolving liquid. The piston device is mounted inside the channel. The guide tube has an end in communication with the channel and an opposite end positioned on the blade to guide the adhesive dissolving liquid contained in the channel to the blade. The present invention uses a tool on which a piston device and adhesive dissolving liquid are provided so that in removing a polarizing sheet, the adhesive dissolving liquid can be guided by a guide tube toward a blade for subsequently flowing toward and dissolving bonding adhesive.
