         2 . The sight as claimed in  claim 1  further comprising a light source, an adjusting seat and an adjusting axle, wherein the light source is disposed on the adjusting seat, and the adjusting dial is configured to move the adjusting seat and the light source through the adjusting axle for elevation adjustments. 
     
     
         3 . The sight as claimed in  claim 2 , wherein the body further comprises an opening, the adjusting axle passes through the opening of the body, and the opening of the body fits the adjusting axle in shape so that the adjusting axle can only be linearly moved but cannot be rotated. 
     
     
         4 . The sight as claimed in  claim 2  further comprising a screw nut, a pressure ring, a hollow screw, a fixing screw, a spring and a steel ball, wherein the screw nut is fixed in the body, the hollow screw comprises internal threads to inwardly engage with the adjusting axle and external threads to outwardly engage with the screw nut and the adjusting dial, the pressure ring is fixed in the body to compress the hollow screw so that the hollow screw can only be rotated but cannot be linearly moved, the fixing screw is fixed to the adjusting dial, and the steel ball is compressed between the hollow screw and the screw nut via the spring. 
     
     
         5 . The sight as claimed in  claim 1  further comprising a light source, an adjusting seat and an adjusting axle, wherein the light source is disposed on the adjusting seat, and the adjusting dial is configured to move the adjusting seat and the light source through the adjusting axle for windage adjustments. 
     
     
         6 . The sight as claimed in  claim 5 , wherein the body further comprises an opening, the adjusting axle passes through the opening of the body, and the opening of the body fits the adjusting axle in shape so that the adjusting axle can only be linearly moved but cannot be rotated. 
     
     
         7 . The sight as claimed in  claim 5  further comprising a screw nut, a pressure ring, a hollow screw, a fixing screw, a spring and a steel ball, wherein the screw nut is fixed in the body, the hollow screw comprises internal threads to inwardly engage with the adjusting axle and external threads to outwardly engage with the screw nut and the adjusting dial, the pressure ring is fixed in the body to compress the hollow screw so that the hollow screw can only be rotated but cannot be linearly moved, the fixing screw is fixed to the adjusting dial, and the steel ball is compressed between the hollow screw and the screw nut via the spring. 
     
     
         8 . The sight as claimed in  claim 5  further comprising a stop part, a spring and a convex axle, wherein the stop part is fixed to the body, the convex axle is fixedly connected to the adjusting seat, the spring is outwardly sleeved on the convex axle and propped against between the stop part and the adjusting seat, and the adjusting seat is located between the spring and the adjusting axle. 
     
     
         9 . A sight, comprising:
 a body comprising a surface; and   an adjusting dial disposed on the surface of the body and protruded from an edge of the surface of the body.   
     
     
         10 . The sight as claimed in  claim 9  further comprising a light source, an adjusting seat and an adjusting axle, wherein the light source is disposed on the adjusting seat, and the adjusting dial is configured to move the adjusting seat and the light source through the adjusting axle for elevation adjustments. 
     
     
         11 . The sight as claimed in  claim 10 , wherein the body further comprises an opening, the adjusting axle passes through the opening of the body, and the opening of the body fits the adjusting axle in shape so that the adjusting axle can only be linearly moved but cannot be rotated. 
     
     
         12 . The sight as claimed in  claim 10  further comprising a screw nut, a pressure ring, a hollow screw, a fixing screw, a spring and a steel ball, wherein the screw nut is fixed in the body, the hollow screw comprises internal threads to inwardly engage with the adjusting axle and external threads to outwardly engage with the screw nut and the adjusting dial, the pressure ring is fixed in the body to compress the hollow screw so that the hollow screw can only be rotated but cannot be linearly moved, the fixing screw is fixed to the adjusting dial, and the steel ball is compressed between the hollow screw and the screw nut via the spring. 
     
     
         13 . The sight as claimed in  claim 9  further comprising a light source, an adjusting seat and an adjusting axle, wherein the light source is disposed on the adjusting seat, and the adjusting dial is configured to move the adjusting seat and the light source through the adjusting axle for windage adjustments. 
     
     
         14 . The sight as claimed in  claim 13 , wherein the body further comprises an opening, the adjusting axle passes through the opening of the body, and the opening of the body fits the adjusting axle in shape so that the adjusting axle can only be linearly moved but cannot be rotated. 
     
     
         15 . The sight as claimed in  claim 13  further comprising a screw nut, a pressure ring, a hollow screw, a fixing screw, a spring and a steel ball, wherein the screw nut is fixed in the body, the hollow screw comprises internal threads to inwardly engage with the adjusting axle and external threads to outwardly engage with the screw nut and the adjusting dial, the pressure ring is fixed in the body to compress the hollow screw so that the hollow screw can only be rotated but cannot be linearly moved, the fixing screw is fixed to the adjusting dial, and the steel ball is compressed between the hollow screw and the screw nut via the spring. 
     
     
         16 . The sight as claimed in  claim 13  further comprising a stop part, a spring and a convex axle, wherein the stop part is fixed to the body, the convex axle is fixedly connected to the adjusting seat, the spring is outwardly sleeved on the convex axle and propped against between the stop part and the adjusting seat, and the adjusting seat is located between the spring and the adjusting axle.
