2, and the holding pieces 53 and 54 formed at the protruding end of the handle 52 so as to protrude in the shape of a pair of wings in the left-right direction with respect to the protruding direction of the handle 52. Although it is the same as the usual one, the pair of wing-like holding pieces 53 and 54 formed at the protruding end of the handle 52 are one side as shown in FIGS. 3 to 5. The length 1 of the holding piece 53 is short and the length 1 of the holding piece 54 of the other holding piece 54 is long. The protruding end 53 of the long holding piece 54 in the rolled-up state follows the aspect of the cord 2 to be held.
a is formed to a length that is located in front of the inside of the long holding piece 54 (FIG. 6), and the long side holding piece 54 is formed with a short side holding piece 54 along the circumferential surface of the cord 2 to be held. The length of the piece 53 is such that the protruding end 54a thereof overlaps the upper surface of the holding piece 53 on the short side when the piece 53 is rolled up.

In addition, in the embodiment, the protruding length of the pair of holding pieces 53 and 54 is such that when the cord holding lug 5 is attached to the body 1, the body 1 is held with the left hand and the cord holding lug 5 is held. When the pieces 53 and 54 are located on the right hand side holding the tool; as shown in FIG. 4, the holding piece 53 on the front side is short and the holding piece 54 on the opposite side is short.
Although the holding pieces 53 and 54 are formed to be long, this is to suit the normal work of bending and caulking the holding pieces 53 and 54 with a tool, and in the state shown in FIG. The holding piece 53 on the front side may be formed to be long.
