PURPOSE: To cut the end of a clip when the end of the clip is twisted and then the force applied to a grid making member reaches a limit value by providing a mechanism for rotating a front jaw in the closed state when the front jaw closes at the end of the crossing member. CONSTITUTION: When a trigger 37 is pulled, an arm 38 of the trigger is brought into contact with a sliding member 42 by a wheel-like member 39, so that a passage 31 is switched to a position indicated by a longitudinal line Y to communicate with a conduit 33 and then communicate with an air hole 34. When the trigger is further pulled, the sliding members 42, 29 come into contact with each other, so that the compressed air is passed through a portion indicated by a signal 43 by the sliding member 29, and further passed through a conduit 45 to reach a motor 25, thereby rotating the motor. The rotation of the motor is transmitted to a spindle, that is, a shaft 56 by a member indicated by a signal 46, and while force is applied to the tip of the clip, that is, the end part, a jaw 48 is rotated to conduct twisting work and breaking work for the clip end. |
