Abstract

A safe remover for window curtain rope is suitable for the connection with a window curtain rope. The safe remover comprises a main body, a buffer seat, an elastic element, and a combined element. The main body comprises a first end portion, a second end portion arranged oppositely to the first end portion, and a chamber defined by the first and second end portions. The buffer seat is insertably arranged in the chamber. The elastic element provides a force for keeping the buffer seat away from the first end portion all the time. The combined element is assembled with the buffer seat by the first end portion and is adapted to be connected with the window curtain rope. Accordingly, when the user exerts a large force to pull the window curtain rope, the force is weakened by the elastic element, and if pull force is continuously increased, the combined element will detach from the buffer seat, thereby ensuring the safety of the user.
