The present invention forms a sickle blade on the back of the sickle used for farming in rural use, and when used as a sickle, the sickle blade is taken out of the sickle house and fixed in a "a" shape, and when used as a saw, the sickle blade is unfolded safely in a straight type. It relates to a folding device of a sickle that has a saw that can also be used as a saw.

The conventional sickle is configured to be used only as a sickle, so that the inner tube is inserted into the exterior fixed to the sickle even in the folding device, and the screw of the inner tube is soldered into the insertion hole of the screw to lead the screw to form the insertion hole. The bow is made by folding the sickle into the bowl and rotating the sickle counter-clockwise to make the sickle stand upright or to be folded at an angle of 90 degrees. A fixed sickle formed by fixing the inner tube, and a sliding mortar having a quadrilateral jaw on the outer circumference, and a rotating exterior with perforated guides on both sides, inserting a sickle, and then folding a sickle (Bob 67-861). Although this is known, all of them are designed to be attached to the sickle with a sickle and detached from the sickle. There was a hassle to complete the bolt frequently.

In order to correct this bleeding, the main office addressed the swivel plate on the back side of the sickle, and in this swivel plate, three fasteners were drilled and the fasteners installed at the upper part of the sickle were allowed to enter and exit the sickle. Folded in sickle, pulled out, and according to the purpose of use, it can be used stably and with a sickle and saw while safely and easily operated in "a" shape and upright state. .

On the other side, a sickle blade (1) is formed, and on the other side, a scorching plate (4) is to be spoken to the fuzl part of the sickle (3), and the pivoting plate (4) is to be spoken. Three rotating holes 5, 5 'and 5' 'are drilled to open passages 6 and 6' in each of the rotating holes 5, 5 'and 5' '. In the upper part of the sickle bag (7), the sliding hole (8) in which the pivoting plate (4) of the sickle (3) can be slitted is cut so that the driving surface (9) can pass through the table surface. ) Perforated the fittings 11, 11 'for fitting the support plates 10, 10', and then the fasteners 12, 12 'and guides 13, 13'. ) Is fitted into the fitting holes 11, 11 'by fitting the support plates 10 and 10' into the fitting holes 11 and 11 ', respectively, and the bolts 14, 14' and 14 " 9 ') (9' '), fasteners 15, 15' and anchoring holes 16, 16 ', respectively, are embedded with sliding bolts 17, 17' in the sliding hole 8 and the bolt ( 14) (14 ') (14' ') of the threaded portion through the screwing holes (18) (18') to be screwed up and down the threaded portion of the screw 16 (16 ') but the bolt (14) (14' 14 " is aligned with the face plates 17 and 17 'such that the ends of the " 14 " do not protrude outward from the mounting holes 16 and 16'.

In the figure, reference numeral 14 '' 'is the bolt, 15' 'and 15' '' are the fixture 3 'is the fixture of the sickle, 19 is the coil spring 20 is the driving, 21 is the wheel, 22 is the guide, 23 is sawing , 24 is fixed and 25 is nut.

The present invention constructed as described above inserts a tackle 17, 17 'into a sliding hole 8 cut off at the upper end of the sickle stool 7, and a rotating plate of the sickle 3 between the tackle 17, 17'. (4) is reinserted so that the fasteners 18 perforated on the pivoting plate 4 are fasteners 15, 15 'on the tackle 17, 17' and the fasteners 15 of the sickle (7). (15 '' ') is finished to be in communication with each other and then the bottom of the fixing rod 24 is screwed into the nut 25 by inserting the fixing rod 24.

The driving rod 20 in which the coil spring 19 is installed on the lower side is inserted into the upper portion from the bottom of the driving hole 9, and the driving interval 20 drives the driving hole 9 ″ punched in the plate 17 ′. Through the rotating hole 5 'of the rotating plate 4 and the driving hole 9' of the plate 17 again, the driving hole 9 in the fitting hole 11 recessed on the surface of the sickle 7 is provided. Allow the tip of the drive rod 20 to be exposed, and then insert the support plates 10, 10 'into the upper and lower fitting holes 11, 11', respectively, to the bolts 14, 14 ', 14 " '' '), So that only the base plate 10, 10' and the plate 17, 17 'are attached, the rotating plate 4 inserted between the plate 17, 17' is a sickle ( 1) It does not interfere with the rotation when standing up or folding, and the driving rod 20 is the driving hole 9 '' of the slide plate 17 'and the rotating hole 5' of the rotating plate 4). When inserted into the driving hole 9 'of the plate 17 and the driving hole 9 of the bag 7 via the driving force, it is driven by the elastic force of the coil spring 19. The tip of the 20 is exposed on the guide 13 installed in the support plate 10, and the wheel 21 of the drive rod 20 is pushed in the rotational hole 5 'so that the sickle 3 Is fixed at a position of 90 degrees.

When the angle of the sickle 3 is to be changed again, the drive shaft 20 is pushed in the pivoting hole 5 'by artificially pressing the tip of the drive shaft 20 protruding on the guide 13. Lower the wheel wheels 21 of the guide rods 22 to enter the pivot hole 5 ', and then the sickle 3 is erected or chopped. The driving rod that was pressurized while entering the upright turning hole 5 or the folding turning hole 5 '' via the passages 6 and 6 'which are cut between 5') and 5 ''. When the tip portion of the 20 is relaxed, the driving wheel 20 is raised by the elastic force of the coil spring 19 while the wheel wheel 21 of the driving wheel 20 is moved back into the rotation hole 5 (5 '' '). The sickle 3 does not flow at all in use because it enters and becomes in a close state, and the sickle 3 is folded according to the purpose of use while simply pressing the upper end of the driving rod 20 by a button type. Or 90 can also be used to expand proudly erect position by using a sickle or free with a saw.
