The present invention relates to a whetstone pedestal that can be quickly changed to a whetstone, to fix whetstone of various lengths, and to adjust the tilt.

A grindstone is used to sharpen a knife or planer blade, etc., and a grindstone stand for fixing the grindstone is required.

When working with a knife, a rough grinding wheel is first used to build a basic blade, and then a fine grinding wheel is used to build the blade. Therefore, you need a whetstone base that can be changed quickly.

1 is a view showing an example of another whetstone pedestal conventionally.

As shown in FIG. 1, the length adjustment of FIG. 1 loosens or tightens the threaded portion 3 of the guide rod 1 with a nut 2 so that the guide rod 1 and the threaded portion 3 slide in the through hole 4. To adjust the length.

Therefore, there is a problem in that the threaded portion of the threaded portion 3 is caught by the sliding surface inside the through hole 4 and thereby wears.

In addition, since there are two fastening members for tightening the whetstone, there is a problem of slow exchange of the whetstone.

2 is a view showing an example of another whetstone pedestal conventionally.

As shown in FIG. 2, if the whetstone (S) is larger than the whetstone pedestal (6), the whetstone (S) protrudes back and forth of the whetstone pedestal (6). There is a problem that can hurt.

In addition, the grindstone pedestal 6 of Figure 2 is a fixed inclination has a problem that the user can not use a convenient inclination.

The present invention is to solve such a conventional problem is to provide a whetstone pedestal that can quickly change the whetstone to the whetstone and can fix the whetstone of various lengths and improved the bearing capacity.

Still another object of the present invention is to provide a whetstone pedestal for arbitrarily adjusting the inclination.

The present invention consists of a "holding member" for supporting a grindstone, a "tightening member" for fixing various grindstones, and a "supporting member" for improving the bearing capacity of the grindstone base, and another object is an "angle adjusting member" for tilt adjustment. Consists of

To achieve the purpose for the quick change of the whetstone, the fastening of the whetstone of various lengths and the improved support of the whetstone pedestal for the purpose of the present invention

The "support member" is composed of a front support portion (10) supporting the front part in the grindstone and a back support portion (11) supporting the rear part in the grindstone, and the circular support featured in the present invention for preventing damage to the grindstone and for quick replacement. The part 12 was made into one and comprised so that it may support the grindstone middle lower part.

"Tightening member" is composed of one fast exchange to the grindstone, and the threaded portion 22 is coupled to the fixed bolt for fastening bolts 24, so the threaded portion to the threaded portion 22 is processed a lot of variable type The whetstone can be fixed.

In other words, the fastening bolt 21 is fastened to the fastening bolt nut 24 by fastening bolt 21 with one handle 20, so that it can be quickly replaced with a whetstone and configured to fix various whetstones in a variable type.

"Support member" is composed of a variable type to improve the bearing capacity of the variable grinding wheel pedestal.

That is, the shaft screw portion 31 is fixed to the shaft nut 32 and the sliding shaft 30 is configured to slide the shaft guide ring 33 to support the whetstone pedestal in a variable type.

To achieve another purpose, the purpose for the whetstone base with adjustable tilt

"Angle control member" has a reference pin and a fixed pin 36 to prevent slipping, and the height can be adjusted by the upper and lower bolts 35 to the fixed upper and lower bolts nut 37 to adjust the angle, so that the convenient inclination It was configured to use a whetstone pedestal.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

Figure 3 is a perspective view of the present invention and Figure 4 is a plan view of the present invention in detail "support member" Figure 5 is a cross-sectional view of the "tightening member" and "support member" in the present invention in detail and Figure 6 is an "angle The adjustment member "is expressed in detail.

As shown, the whetstone base supports the front part on the whetstone to the front support part 10 and the back part opposite to the back support part 11 and prevents damage to the whetstone and sees the lower part of the middle part on the whetstone for quick exchange. To support the circular support 12 characterized by the design

It consists of a "support member".

Therefore, the circular support portion 12, which is characterized in the present invention, acts as a sliding action on the tightening bolt 21 of the "tightening member", while smoothly rotating the tightening bolt 21 while supporting the lower portion of the grindstone, so that it breaks on the grindstone. And the "tightening member" can be composed of one to allow for quick exchange of the grindstone.

As shown in detail in FIG. 5, when the tightening bolt 21 is tightened with the handle 20, the screw part 22 is coupled to the nut 24 for the tightening bolt, and thus the front support part 10 and the back support part 11 are provided. The "tightening member" is configured with a variable type so as to fix the whetstone in between.

Therefore, the present invention is composed of a single "tightening member" is quick to exchange on the grindstone, and by processing a lot of threaded portion on the threaded portion 22 to be able to fix a variety of grindstone to the grindstone base.

And in order to increase the bearing capacity of the grindstone pedestal to the variable type, the "support member" is fixed to the shaft nut part 31 and the sliding shaft 30 is the shaft guide ring as shown in detail in FIG. It is comprised so that it may slide along (33).

Therefore, even if the whetstone pedestal of the variable type fixed the whetstone of various lengths, the sliding shaft 30 in the "support member" while sliding to the guide ring 33 to increase the support force to the whetstone pedestal in a variable type at various lengths.

In addition, "angle control member" so that the use of the grindstone pedestal at a convenient inclination constitutes a fixing pin 36 to prevent the reference height and slip on the grindstone as shown in detail in Figure 6 and fastened to the nut 37 for the upper and lower bolts The height of the upper and lower bolts 35 is adjusted to adjust the angle and is configured to use a grindstone pedestal with a convenient slope.

Therefore, the upper and lower bolts 35 and the fixed pin 36, the pointed end portion is fixed at various angles on the bottom surface and does not slip on the bottom surface during knife grinding operation so that the grindstone pedestal does not flow.

In addition, by adjusting the height of the upper and lower bolts (35) to use a grindstone pedestal with a convenient slope.

As described in detail above, the front support portion 10, the rear support portion 11 of the "support member" to support the bottom of the front and rear to the wheel and the handle 20 of the "tightening member" to the circular support portion 12 characterized in the present invention Rotating the tightening bolt 21, the threaded portion 22 is coupled to the fastening bolt nut 24 to fasten the whetstone of various lengths, and the "support member" is the sliding shaft 30 is the shaft guide ring ( 33) to support the grindstone stand in various length variations.

In addition, the upper and lower bolts 35 and the lower end of the fixing pin 36 of the "angle control member" do not flow the grindstone base when cutting the knife and the upper and lower bolts 35 to the nut 37 for the upper and lower bolts. The grindstone stand can be used on a slope with easy height adjustment.
