Structure improvement of electric grinder

Abstract

The present invention relates to a structure improvement of electric grinder, and more particularly to the structure improvement of an electric grinder whose components can be quickly assembled and disassembled. It mainly comprises a control element formed inside of an outer casing, wherein the control element includes a transmission shaft and on the rod of the transmission shaft includes several lengthwise cutout slots so the front forms several petal-like clip pieces to hold a bit, while the rear section of the transmission shaft is lock connected with a transmission element and the transmission element is connected with a motion element through insertion to proceed grinding motion, wherein the characteristics includes: a transmission element, whose insertion section includes a shaft to prevent the eccentric movement of said transmission element and a connecting element, which includes a groove at the end and more than one holes and after placing round beads and inserting a resilient element, a motion element can be connected by the resilient element, and therefore the uses can quickly disassemble the motion element and the electric grinder.

I claim:  
     
         1 . A structure improvement of electric grinder, mainly comprises a control element formed inside of an outer casing, wherein said control element includes a transmission shaft and on the rod of said transmission shaft includes several lengthwise cutout slots so the front forms several petal-like clip pieces to hold a bit, while the rear section of said transmission shaft is connected with a transmission element, and said transmission element is connected with a motion element through insertion so the rotation of said motion element causes said transmission element to rotate and proceed grinding motion, wherein the characteristics may include: 
 a transmission element, whose insertion section includes a shaft to prevent the eccentric movement of said transmission element;    a connecting element, which includes a groove at the end of said connecting element and holes so after placing round beads and inserting a resilient element, a motion element can be connected by said resilient element;    a motion element, whose main component is a hollow soft tube which further includes a transmission wire, and the top section of said motion element includes a connecting section and a surrounding groove to position said round bead of said groove when said connecting section of said motion element is inserted into the internal trough of said connecting element.
