Ergonomic leveler

Abstract

An ergonomic leveler has a base and a spin cover. The base has a clamping board, a connecting slice, and a connecting rod. The spin cover is detachably connected to the base and has a screw portion and a spin portion. The screw portion is disposed on a top of the spin cover and is connected to the connecting rod. The spin portion is connected to the screw portion, is a cover structure with an opening facing downward, and has at least one rotating strip. The at least one rotating strip is disposed curvedly on and extends out of an external surface of the spin portion along a direction from the screw portion toward the opening. Each one of the at least one rotating strip has an abutted-curved face disposed on an outer side of the rotating strip away from the screw portion.

         4 . The ergonomic leveler as claimed in  claim 3 , wherein
 each abutted hole is a non-circular structure; and   each auxiliary contact surface is connected to the abutted-curved face of one of the two adjacent rotating strips.   
     
     
         5 . The ergonomic leveler as claimed in  claim 4 , wherein the spin cover has a reminder symbol disposed on at least one of the auxiliary contact surfaces. 
     
     
         6 . The ergonomic leveler as claimed in  claim 1 , wherein the spin cover has a pressing flange annularly formed on a bottom of the spin portion. 
     
     
         7 . The ergonomic leveler as claimed in  claim 1 , wherein the screw portion has multiple protruded ribs formed on an external surface of the screw portion at spaced intervals. 
     
     
         8 . The ergonomic leveler as claimed in  claim 1 , wherein the clamping board has
 a clamping face disposed on a top side of the clamping board; and   at least one clamping portion disposed on each one of two ends of the clamping board, and each one of the at least one clamping portion having multiple abutted teeth arranged in a stepped manner on a bottom surface of the clamping portion.   
     
     
         9 . The ergonomic leveler as claimed in  claim 2 , wherein the clamping board has
 a clamping face disposed on a top side of the clamping board; and   at least one clamping portion disposed on each one of two ends of the clamping board, and each one of the at least one clamping portion having multiple abutted teeth arranged in a stepped manner on a bottom surface of the clamping portion.   
     
     
         10 . The ergonomic leveler as claimed in  claim 3 , wherein the clamping board has
 a clamping face disposed on a top side of the clamping board; and   at least one clamping portion disposed on each one of two ends of the clamping board, and each one of the at least one clamping portion having multiple abutted teeth arranged in a stepped manner on a bottom surface of the clamping portion.   
     
     
         11 . The ergonomic leveler as claimed in  claim 4 , wherein the clamping board has
 a clamping face disposed on a top side of the clamping board; and   at least one clamping portion disposed on each one of two ends of the clamping board, and each one of the at least one clamping portion having multiple abutted teeth arranged in a stepped manner on a bottom surface of the clamping portion.   
     
     
         12 . The ergonomic leveler as claimed in  claim 5 , wherein the clamping board has
 a clamping face disposed on a top side of the clamping board; and   at least one clamping portion disposed on each one of two ends of the clamping board, and each one of the at least one clamping portion having multiple abutted teeth arranged in a stepped manner on a bottom surface of the clamping portion.   
     
     
         13 . The ergonomic leveler as claimed in  claim 8 , wherein the connecting slice is connected to the clamping face of the clamping board and has a through hole formed through the connecting slice between the clamping board and the connecting slice. 
     
     
         14 . The ergonomic leveler as claimed in  claim 9 , wherein the connecting slice is connected to the clamping face of the clamping board and has a through hole formed through the connecting slice between the clamping board and the connecting slice. 
     
     
         15 . The ergonomic leveler as claimed in  claim 10 , wherein the connecting slice is connected to the clamping face of the clamping board and has a through hole formed through the connecting slice between the clamping board and the connecting slice. 
     
     
         16 . The ergonomic leveler as claimed in  claim 11 , wherein the connecting slice is connected to the clamping face of the clamping board and has a through hole formed through the connecting slice between the clamping board and the connecting slice.
