Description of the Related Art The inventor has previously devised a rocking clamp provided with a contact piece for reinforcing the connection strength as an improvement of a steel frame clamp (Utility Model Registration No. 2146102). This rocking clamp provides a rocking clamp with extremely high connection strength by fixing the two side edges of the substantially T-shaped contact piece in a state of always contacting the section steel. . This rocking clamp is composed of a substantially U-shaped side connecting piece that is connected and fixed to a steel frame, and a clamp body that grips a temporary pipe. The clamp body is provided with a substantially T-shaped contact piece, Regardless of whether the mounting angle of the clamp body is horizontal or vertical, the two contacting portions reinforce contact with the steel frame to increase the connection strength of the clamp body.

など、作業の妨げになることがわかってきた。However, in the swing clamp invented by the present inventor, the connection strength could be increased by a substantially T-shaped contact piece, but the swing clamp was provided outside the connection body. Since the T-shaped abutting piece is exposed, it has been found that the abutting piece hinders the work, such as being hooked on a worker's clothes after connection and mounting.
