Detailed Description

The invention is described in detail below with reference to the drawings and the detailed description.

As shown in fig. 1 to 4, the connection fastening tool provided by the present embodiment is mainly applied to a straight-line type reinforcing bar straight-thread connection, and clamps and rotates the straight-line type reinforcing bar straight-thread connection. The connecting and fastening tool mainly comprises a handle 10, a fixed binding clip 20, a movable binding clip 30 and a rotating piece 40. The fixing jaw 20 is provided at the front end of the handle 10, and specifically, the fixing jaw 20 is fixed at the front end of the handle 10 by welding. The movable binding clip 30 is hinged to the fixed binding clip 20, and in particular, may be connected by a pin. The rotating part 40 is detachably connected with the handle 10, and the included angle between the rotating part 10 and the handle is 90 degrees. The movable binding clip 30 is used for fitting one side surface of the linear reinforcing steel bar, the fixed binding clip 20 is used for abutting against the other side surface of the linear reinforcing steel bar, and the linear reinforcing steel bar is clamped tightly by matching the movable binding clip and the fixed binding clip. During the use, handheld rotating member 10 is around the circumference rotation of linear type reinforcing bar, and its turned angle is 0-360 degrees, can realize carrying out threaded connection to linear type reinforcing bar uninterruptedly in succession, has improved the connection speed to fastening process moment has evenly guaranteed fastening quality.
