Description

Skin grinder with form

Technical field

The utility model relates to a kind of skin grinder, refers to that especially a kind of operation has the skin grinder of form easily.

Background technology

Existing milling tool can be said with reference to patents such as TaiWan, China I329547 or M349818, and main compressed gas-driven air motor capable of using further utilizes air motor to drive abrasive disk and rotates, and supplies operations such as the user grinds, polishing to use.

Because this kind milling tool mainly is to utilize abrasive disk that surface of the work is ground, after using certain hour, abrasive disk will consume gradually and the needs of changing abrasive disk are arranged.When the dismounting and change abrasive disk,, directly rotate abrasive disk and will rotate together with the rotating shaft of air motor because abrasive disk is assembled in the rotating shaft of air motor; And can't dismantle smoothly, the user need squeeze and open the guard shield at abrasive disk rear with spanner or similar means; Stretch between abrasive disk and the guard shield; Further clamp just can be avoided the rotating shaft of air motor when dismounting, to rotate arbitrarily, and can rotate the dismounting abrasive disk smoothly in rotating shaft or abrasive disk locking place.

By on can know that the user need push during abrasive disk and makes the guard shield distortion in dismounting, could instrument be stretched into the abrasive disk rear, not only very inconvenience in the operation also maybe be because of shortening its life-span with the guard shield torsional deformation arbitrarily.In addition, when the user stretched into instrument, owing to receive shield blocks, whether the instrument of can't seeing was relative with the position of desiring clamp, further causes the obstruction of manipulating.
