If it is difficult to disassemble the scissors, It is also possible to mount it on the member 400.

Then, the support bar 300 is rotated to place the scissors blade 10 mounted on the clamp member 400 at a desired polishing angle. First, as shown in FIG. 5A, the reference member 500 is rotated so that the reference bar 510 is supported on one side of the latching portion 240 of the support block 200. At this time, the reference bar 510, the reference scale 520, and the support bar 300 are aligned in the same direction.

Next, as shown in Fig. 5 (b), the support bar 300 is rotated while the reference member 500 is fixed, and the scissors blade 10 is laid down at a desired polishing angle. The supporting bar 300 and the scissors blade 10 are rotated at a desired angle by aligning the scale 321 of the scale member 320 with respect to the reference scale 520 of the reference member 500 . For example, when the scales 321 of the scale member 320 are uniformly formed at intervals of 1 degree along the periphery, the user can rotate the support bar 300 in units of 1 degree until a desired angle is obtained.

After the support bar 300 and the scissors blade 10 are rotated at a desired angle, the pressing member 600 is fastened in the direction of the reference member 500 so that the reference member 500 presses and supports the scaling member 320 do. At this time, the reference member 500 and the graduation member 320 come into close contact with each other and rotate integrally.

Then, the link member 700 is appropriately expanded or collapsed according to the distance between the abrasive machine and the base block 800, thereby bringing the blade portion of the scissors blade into contact with the surface 20 of the abrasive machine. The grinder grinds the blade portion of the scissors blades 10 while rotating or linearly moving, at which time the scissors blades 10 are polished at a constant blade angle.

5 (b), the reference bar 510 is caught by the catching part 240 in a state where the reference member 500 is pressed against the scale member 320, The scissors blade 10 is restricted from rotating in one direction (clockwise direction in the drawing). 5 (c), when the support bar 300 and the scissors blade 10 are rotated in opposite directions (counterclockwise in the drawing), the scissors blade 10 is detached from the grinder, The work will not be performed. Accordingly, the scissors blade 10 mounted on the jig 100 according to the embodiment of the present invention always maintains a constant grinding angle during the grinding operation, and the scissors blade 10 is polished at a desired blade angle You can do it.

In this case, when the user folds or unfolds the link member 700, the support bar 300 may be curved in a curved shape, So that the blade or the scissors blade 10 can be polished. It goes without saying that the blade portion can be uniformly polished at a desired blade angle.
