The utility model relates to the field of ejection hooks, in particular to an arrow-shaped ejection hook which comprises a base band and hook bodies evenly distributed on the surface of the base band, each hook body comprises a connecting column body and a connector arranged on the connecting column body, two barb portions inclining towards the two sides respectively are formed on the top of each connector, and the two barb portions are arranged on the base band. The two inclined barb parts are arranged on the two sides of the connector, the two barb parts are symmetrically arranged on the two sides of the connector, the bottoms of the two barb parts are respectively provided with an arc-shaped hook face which is concave inwards, and a circular arc-shaped transition face is formed at the connecting vertex of every two adjacent inclined barb parts. The bottom of the barb part is designed to be an inwards-concave arc-shaped hook surface, so that the connection firmness and reliability of the hooked grid and the barb part are further ensured, the pressing and buckling use of an external matching tool is reduced, on the contrary, when the grid is disassembled, the damage to the hooked grid is reduced through the arrangement of the arc-shaped hook surface, and therefore the bonding use efficiency and convenience of the ejection hook are improved.
