Shaft with bolts, bolts and nuts
By combining the opening degree in parallel at 14
Even if an elastic body is not interposed, the inner surface of the second bracket 12 is urged to press the outer surface of the third bracket 7B, 8B so that the inner surface of the third bracket 7B, 8B is arbitrarily bent by stepwise locking at the uneven portion 17. The angle can be maintained. At this time, the second
The degree of opening of the bracket 12 is made smaller than that in the parallel state (FIG. 17C), and the third bracket 7B, 8B whose degree of opening is made larger than that in the parallel state is assembled so that the degree of opening becomes parallel. If this is the case, the pressing force between the two brackets 7B and 12, and 8B and 12 becomes large, so that an arbitrary bending angle can be held more reliably, and the third bracket 7B,
8B can be assembled by distributing the outward pressing force of the second bracket 12 to the inward pressing force of the second bracket 12, and the amount of deformation is smaller than in the case where only the outward pressing force of the third brackets 7B and 8B is used. It is possible to avoid the possibility of breaking the waist.

Even if an elastic body is not interposed, the inner surface of the second bracket 12 is urged to press the outer surface of the third bracket 7B, 8B so that the inner surface of the third bracket 7B, 8B is arbitrarily bent by stepwise locking at the uneven portion 17. The angle can be maintained. At this time, the second
The degree of opening of the bracket 12 is made smaller than that in the parallel state (FIG. 17C), and the third bracket 7B, 8B whose degree of opening is made larger than that in the parallel state is assembled so that the degree of opening becomes parallel. If this is the case, the pressing force between the two brackets 7B and 12, and 8B and 12 becomes large, so that an arbitrary bending angle can be held more reliably, and the third bracket 7B,
8B can be assembled by distributing the outward pressing force of the second bracket 12 to the inward pressing force of the second bracket 12, and the amount of deformation is smaller than in the case where only the outward pressing force of the third brackets 7B and 8B is used. It is possible to avoid the possibility of breaking the waist.

当たってしまう虞を無くすことができる。According to the present invention, a pair of first and second handle portions rotatably connected via a first shaft at the intersecting portions are connected to a pair of first and second handle portions via first and second universal joints. The base ends of the first and second scissor blades are connected to each other, and the substantially central portions of the first and second scissor blades are crossed, and the crossing portion is rotatably connected via a second shaft. In the mowing scissors, the first and second universal joints are located between the base ends of the first and second scissor blades and the first and second universal joints.
Mowing scissors characterized in that a joint for bending the scissor blade body is provided, wherein the angle between the handle and the scissor blade body is changed at any angle. Is pivotally connected via the first shaft at the tip end of the handle, so that the force applied to the grip portion is transmitted to the universal joint attached to the tip of the handle portion, which is substantially coplanar, by leverage. In addition, the universal joint reliably transmits the cutting edge of the scissors blade body on the substantially same plane, so that, for example, the grass on the step surface or under the standing tree can be adjusted to any angle suitable for the situation. It can be used as a cutting scissor by extending the handle and the scissors blade almost straight, and the use thereof can be expanded. By bending the first and second scissor blades toward the handle, the scissor blades do not become bulky during transportation, and may be inadvertently hit by the scissor blades during product display. Can be eliminated.
