Description

M252534 9. Creation instructions (1) [Technical field to which the new type belongs] This creation is about a structural improvement of sawn wood and other suitable hard objects. You Caiyi said that its IS film can adjust the angle with the grip to Convenient for different places, items can be cut with a convenient posture and angle. [Previous technology] According to the current saws for general wood sawing, they all include a handle, and a saw blade is fixed to the handle square. In this fixing method, the angle between the saw blade and the handle cannot be changed. In the case of inconvenient items or places, the work progress will be slow and unsuccessful. In addition, there is also a foldable type, but it is only for convenience and safety, so it also has the above-mentioned lack of use. [New items are slow and slow. A saw blade is provided with a convex point in the front, an index prevention slot is provided, and an inner side is protected.] The saw on or off the place is smooth. Provided by the creation, a positioning center with a receiving groove and a recess on the center surface, a saw, and a central turning projection. When the handle and saw are used to lock the surface, there is no wrong screw, and there is an outer structure. It is a solid method to effectively improve the structure and a sixteen 'receiving groove is provided with a perforation on the arc-shaped bottom edge, the arc-shaped locking knot at the lower portion of the penetrating plate is provided with a through hole, and the positioning screw button is centrally extended, and the above knot is used together' When it is inconvenient to apply force, the progress of work will be included. It includes: a grip, an angle nut, one side of the grip is equidistantly provided with a plurality of positioning holes, and the other is provided with a recessed portion equidistantly provided with a plurality of fixed positions. The thread end of the thread section is convexly provided with a large inner small second-order hole. The angle of the saw can be adjusted.

The dry positioning slot (2 2) is located in the lock knot (2 3), and the threaded section (31) of the set screw (30) is used to facilitate the hand to have a second-order hole with an outer size and an inner size. (4 1) (42). A central hole is provided on the center of the part, a convex shape is provided on the end, and an anti-rotation convex grip is provided. The central side is provided with a flat locking surface and its mouth is exactly as shown in Figure 2. As shown in the combined plan view, the locking portion (21) of the saw blade (20) fits into the holding groove (丨) of the handle (10), and at the same time, the positioning through groove (22) is aligned with the positioning convex point (12). ) Fit each other, '(23) will be perforated (13), and then set screws (30) from the other side, two holes, and anti-rotation bumps (3) will fit into the anti-rotation recess (⑷ 中, = Hex nut (50) snaps into the second-stage hole (41) of the knob (40) for preliminary ^: position, and finally the hex nut (50) on the knob (40) is provided for the above to pass through = The screw (30) is locked and fixed, and the locking surface (42) is used to press the ^ j (2υ) of the saw blade (20) tightly against the groove (11) groove surface of the grip (10). [Same as See the combined cross-sectional view of the creation in Figure 3]. 'When adjusting the angle as much as the saw blade in Figure 4 adjusts the movement of the sound and the picture (also refer to Figure 2 in the creation of Figure 2) Section A ~ a of the figure ^ Figure) 'Simply rotate by hand The knob (40) makes it loosen the set screw (30) and the hex nut (50) with the second hexagonal hole (41) of the same hexagon. At this time, the set screw (30) will also prevent the convex block ( 31) The part is restricted by the rotation-prevention recess (14) to prevent rotation. When the opening is turned to an appropriate height, the positioning slot (22) of the saw blade (20) can be separated from the positioning protrusion (12), and the position can be adjusted. Saw blade (20) through-hole (23) is the center of rotation. Saw blade (20)-appropriate angle is required, and then the knob (40) is tightened. The adjustment process requires no other tools at all.
