Claims

[Claims for Utility Model Registration] An improved drill grinder consisting of the following parts: A main frame; A grinding wheel movably attached to a grinding device mounted on the main frame; A rib formed on the upper part; a first sheet mounted on top of the main frame, a second sheet having ribs perpendicular to the ribs of the first sheet, a second sheet mounted on top of the first sheet and movable along the ribs of the first sheet; movably mounted on the second seat;
a third sheet movable along the ribs of the second sheet; an L-shaped stand pivotally mounted above the third sheet and capable of changing its position relative to the grinding wheel of the polishing device; a block attached to one end of the handle of the stand, the block having a dovetail groove, and the block having a recess in which a gear is attached; and is constructed so that the gear can be turned by turning a knob attached to the gear through the block; it has a dovetail tenon that fits into the dovetail groove of the block; A sliding seat capable of sliding along a groove, which is attached to the dovetail tenon and has a rack that engages the gear of the block, so that when the gear rotates in a predetermined manner, the sliding seat slides along the dovetail groove of the block. A clamping device that slides up and down, and further has a support plate on the sliding sheet, the center line of which intersects the center line of the sliding sheet at an angle of 45 degrees; a clamping device consisting of a first sheet and a second sheet; the first sheet is close to the second sheet and can be adjusted so that the drill bit can be sandwiched between them;
and the clamping device is mounted on the support plate of the sliding seat, where the drill bit is configured to come into contact with the grinding wheel; an L-shaped positioning seat with a slot, along which the positioning member is moved; The stereotactic member has a screw that allows it to be fixed at a specific position, and the mark on the stereotactic sheet is configured to indicate the specific position of the stereotactic member.
