Interconnectable candle holder

An interconnectable candle holder, having a top surface formed with an opening, the opening extending inward along a longitudinal direction of the interconnectable candle holder to form a receiving space, the receiving space being configured for allowing insertion of a candle into the receiving space, the interconnectable candle holder having a lateral surface which is adjacent to the top surface and is formed with a groove, the groove extending along the longitudinal direction of the interconnectable candle holder to a bottom surface of the interconnectable candle holder and communicating with the receiving space, the interconnectable candle holder forming a convex surface corresponding in position to the groove, the interconnectable candle holder further having a lateral surface which is adjacent to the top surface and is formed with a ridge, the ridge extending along the longitudinal direction of the interconnectable candle holder to the bottom surface of the interconnectable candle holder, the ridge having an end surface which faces away from the interconnectable candle holder and is concavely provided with a concave surface, the ridge corresponding in configuration to the groove, the concave surface corresponding in configuration to the convex surface, wherein when a first said interconnectable candle holder is connected to a second said interconnectable candle holder having a same height as the first interconnectable candle holder by the groove of the first interconnectable candle holder and the ridge of the second interconnectable candle holder, a space into which the candle is still insertable is defined by the receiving space of the first interconnectable candle holder and the concave surface of the ridge of the second interconnectable candle holder.
