Preferably, the pressing plate is L-shaped.

The present invention uses process as follows:

Rotate the handle to increase the distance between the outer frame and the pressure plate, push the whetstone into the outer frame and close to the end of the pressure plate, turn the handle clockwise to lower the pressure plate until the whetstone is firm and not loose, and hold the tail of the outer frame to repair it back and forth on the grinding wheel when trimming. When the strip loss is close to the outer frame, turn the handle counterclockwise to extract the rest of the whetstone strip, and keep 20mm in the outer frame for secondary compression, and continue to use it until it is close to the end of the outer frame.

Compared with the prior art, the beneficial effects of the present invention are: the utility model has simple structure and easy operation, and the current situation is improved by clamping. A clamp is installed at one end of the whetstone bar, and half of the grinding wheel is placed in the clamp. The operator only needs to Hold the jig for correction. When the whetstone strip is worn down to close to the jig, turn the handle to open the pressure plate, extract the remaining part of the whetstone strip, and continue to use the compressed part. The utilization rate is 50% of the original, and it is increased to 90%. Improve the utilization rate and avoid potential safety hazards.
