このような欠点を除去しようとするものである。In a folding type saw of this type, when the handle and the saw blade are connected by a fulcrum shaft, when the saw blade is replaced, the fulcrum shaft is removed and the entire saw is removed. Must be disassembled, and when the saw blade is fixed by a hook attached to the handle,
Not only is the fixing operation troublesome, but there is the inconvenience that the saw blade can only be fixed at a specific position. This type of folding saw is often used for pruning of plant trees, etc., and if the angle between the handle and the saw blade can be freely set depending on the situation at the time of work, it will be very easy to use, When the saw blade is fixed by a hook when in use, the saw blade cannot be set at a convenient angle, and the fixing screw attached to the side is tightened. In this case, the work of tightening or loosening the screw is troublesome, and if such an operation is performed frequently, there is a drawback that the fingertip is damaged. The present invention seeks to eliminate such drawbacks found in conventional configurations.

在の状態となるのである。A handle 2 and a back metal 5 which constitute the saw handle body 1.
Although the above-described configuration is used, the back metal 5 is attached to the handle 2 by attaching the back metal 5 to the gap between the support portions 4 formed on the handle 2 as shown in FIGS. 2, 4, and 5. After inserting the base portion and bringing the hole 6 formed in the support portion 4 and the hole 8 formed in the back metal 5 into the same state, a fulcrum shaft 12 having a head portion 10 is inserted, and the fulcrum shaft 12 of the fulcrum shaft 12 is inserted. This is done by attaching the pressing tool 14 to the tip end portion in a swingable state. That is, the fulcrum shaft 12 is the head 1
0, the angular shaft portion 11, the thick shaft portion, and the paragraph-shaped thin shaft portion are formed, and the hole 13 into which the pin 16 can be inserted is formed near the tip of the thin shaft portion. On the other hand, as shown in FIG. 2, the pressing tool 14 has a through hole 15 into which the pin 16 can be inserted at the edge portion, and a part of the rear surface side of the through hole 15 is projected. Is formed, and a notch 17 having a width into which the tip of the fulcrum shaft 12 can be inserted is formed in the central portion of the edge portion of the fulcrum shaft 12. After the tip portion is made to project from the side surface portion of the support portion 4, the disc-shaped spring 19 is made to be along the side surface portion of the support portion 4 and is inserted and arranged in the notch portion 17 of the pressing tool 14, A hole 1 in which a pin 16 inserted from above the pressing tool 14 is formed on the fulcrum shaft 12 By pledge within,
The pressing tool 14 is attached to the fulcrum shaft 12 so as to be swingable. Therefore, when the pressing tool 14 is swung to the near side, the bulging portion 18 formed on the pressing tool 14 pressurizes the disc spring 19 and simultaneously presses the side surface portion of the support portion 4, The concavo-convex portion 7 formed on the side portion of the support portion 4 and the concavo-convex portion 9 formed on the side portion of the back metal 5 are locked and fixed to fix the handle 2 and the back metal 5, When the pressing tool 14 is raised to the front side, the pressing state by the pressing tool 14 is released, and the engagement state between the uneven portion 7 formed on the support portion 4 and the uneven portion 9 formed on the back metal 5 is released, The back metal 5 is rotatable with respect to the handle 2.
