Claims

[Scope of claim for utility model registration] A temporary frame ratchet handle used for tightening formwork for pouring concrete during construction or civil engineering work, which has a wrench part connected to a ratchet mechanism at one longitudinal end. The other end in the longitudinal direction has a socket accommodating part which is a hollow part and accommodates a socket attached to the handle, and the socket accommodating part has a hexagonal top part of the socket in a continuous part between the large diameter part and the small diameter part. are formed by facing each other to expose elongated holes, and in the vicinity of each of these elongated holes are arranged holes in which a spring protrusion disposed on the socket side engages when the hexagonal top of the socket faces the elongated hole. A temporary frame ratchet handle characterized by being formed.
