发明名称 Thee hinge pin remover
摘要 This is a device use for removing a hinge pin from its hinge assembly safely, quickly, and easily, using lever action instead of the traditional hammering or banging. This device is placed over the top of the door hinge, where it rests by grabbing the head of the hinge pin. It has a handle that is attached to a gear wheel, which rotates on a shaft, when the handle is moved up and down. It has an L shaped arm that has a thin rod attached to it lower part. The L shaped arm has teeth on it backside, which interlocks with the gear wheel. When the handle is pulled sown, the gear wheel rotates and raised the L shaped arm. This raises the thin rod that is attached to the L shaped arm, which in turn pushes up against the bottom of the hinge pin, thus raising the hinge pin up and out of the door hinge assembly.
