A long-
tail clamp comprises a clamp body, wherein the clamp body comprises clamping edges and a
ridge portion, a clamping groove is formed in the
ridge portion, one face of the clamping groove is open, and the opening of the clamping groove points to the clamping edges. The clamping groove comprises a first straight baffle and first transverse baffles, wherein the first straight baffle is fixed to the
ridge portion, the first transverse baffles are connected to the first straight baffle in a
lap joint mode, a strip-shaped protrusion is arranged on the portion, located on the opening of the clamping groove, of the ridge portion, the height of the strip-shaped protrusion is smaller than the height of the first straight baffle, an inclined block is arranged on the side, inside the clamping groove and close to the opening, of the ridge portion, the height of the inclined block gradually decreases from the opening to the bottom of the clamping groove, and the height of the inclined block is smaller than that of the strip-shaped protrusion. A
label is arranged in the clamping groove, and the
label is matched with the clamping groove. The
label is arranged on the long-
tail clamp, the label is well combined with the clamping groove and is not prone to falling, files are convenient to find, time is saved, and daily working efficiency is improved.
