The invention discloses a novel self-resetting shearing type lead damper. The novel self-resetting shearing type lead damper comprises a left lug plate, an auxiliary cylinder, a first spring, a main cylinder, an outer barrel, a lead core, an end cover, a right lug plate, a second spring, a first baffle and a second baffle, wherein the right end of the main cylinder and the right lug plate are connected into a whole through a thread pair, the left end of the main cylinder is embedded into the auxiliary cylinder to form sliding fit, the left end of the auxiliary cylinder and the left lug plate are connected into a whole through a thread pair, the first spring is arranged on the inner sides of the main cylinder and the auxiliary cylinder, the left end of the first spring and the left lug plate are fixed into a whole, and the right end of the first spring and the right lug plate are fixed into a whole; the outer barrel is arranged outside the main cylinder, the inner side of the left end of the outer barrel is connected with the auxiliary cylinder into a whole through a thread pair, and the inner side of the right end of the outer barrel is connected with the end cover into a whole through a thread pair; the first baffle is vertically arranged on the outer barrel, the second baffle is vertically arranged on the main cylinder, and the second spring is arranged between the first baffle and the second baffle; the lead core is embedded into a gap ring groove formed between the main cylinder and the outer barrel, the main cylinder drives the lead core to slide relatively when sliding, and energy is consumed in a shearing mode.
