方向に変形させるようにしている。As a fastening tool for the hose band, the one described in US Pat. No. 3,216,291 has been conventionally known. In this fastener, a push claw is provided at each tip of a pair of handles that can be opened and closed, and the bent portion 14 of the hose band is positioned between the pair of open claws to grip the pair of handles. By operation, the pair of push claws are moved inward to deform the pair of side walls 14a of the bent portion 14 inward.

る。By the way, in the above-mentioned fastener, it is necessary to increase the lever ratio of the length from the opening / closing center of the handle to the force point of the handle and the length from the opening / closing center to the point of action of the push claw. Although the hose band can be tightened with a small force, in this case, the total length of the tightening tool becomes long, and the opening / closing angle of the pair of handles becomes large, which causes a problem in operability. On the other hand, if the lever ratio is reduced, a large force is required to tighten the hose band.

【実施例】以下、この発明の実施例を添付図面に基づい
て説明する。Embodiments of the present invention will be described below with reference to the accompanying drawings.
【0011】図1乃至図3に示すように、一対のハンド
ル1a、1bの先端部は軸2を介して開閉自在に連結さ
れている。As shown in FIGS. 1 to 3, the tip ends of the pair of handles 1a and 1b are connected via a shaft 2 so as to be openable and closable.
【0012】一対のハンドル1a、1bの先端部外側に

ガイド孔7内にスライド自在に挿入される。Inside the support frame 3, a pair of levers 5a,
5b is inserted. The intersection of the pair of levers 5a, 5b is openably and closably connected by a pin 6, and both ends of the pin 6 are slidable in a guide hole 7 formed of an elongated hole formed in each side plate 4 of the support frame 3. Inserted in.

ホースバンド11の幅寸法より大きくなっている。The rear end portions of the pair of levers 5a and 5b are connected to the front end portions of the handles 1a and 1b through connecting pins 8. Further, the tip ends of the pair of levers 5a and 5b are bent in opposite directions to form push claws 9a and 9b, and the width dimension of the push claws 9a and 9b is the width dimension of the hose band 11 shown in FIG. It is getting bigger.
【0015】いま、一対のハンドル1a、1bを開放す
ると、一対のレバー5a、5bの後端部が離反する方向
に動くため、一対の押し爪9a、9bが開放する。Now, when the pair of handles 1a, 1b is opened, the rear end portions of the pair of levers 5a, 5b move in the direction of separating, so that the pair of push claws 9a, 9b are opened.

内方向に変形させる。When tightening the hose band 11 shown in FIG. 4, with the pair of push claws 9a and 9b opened, the hose band 1 is placed between the pair of push claws 9a and 9b.
One bent portion 14 is positioned, and in that state, the pair of handles 1a and 1b are gripped, and the pair of push claws 9a and 9b are moved in the closing direction to deform the pair of side walls 14a of the bent portion 14 inward.

下げられ、ガイド孔7に沿って移動する。When the pair of push claws 9a, 9b move in the closing direction, the handles 1a, 1b and the lever 5 are moved.
Since the pin 6 connecting the a and 5b moves in an arc around the shaft 2 which is the opening / closing center of the handles 1a and 1b,
The pin 6, which is the opening / closing center of the pair of levers 5 a and 5 b, is pulled down and moves along the guide hole 7.
【0018】このため、一対の押し爪9a、9bは閉じ

って端壁14bが成形される。Therefore, the pair of push claws 9a and 9b move toward the end surface 10 of the support frame 3 while moving in the closing direction, and as shown in FIG.
4b contacts the end surface 10 of the support frame 3, and the end surface 10 forms the end wall 14b.
【0019】このとき、支持枠3は、軸2とピン6によ
