Power twister with adjustable resistance

Abstract

A power twister with adjustable resistance has two elastic components, two handles, two adjusting components, and a positioning assembly. The two elastic components are each respectively made of a rod rolled up spirally. The two handles are each respectively a bar, and are each fixed with a respective one of the two elastic components. The two adjusting components are each fixed with a respective one of the two elastic components, and each has a respective socket. The two sockets of the two adjusting components have multiple teeth meshed together. The positioning assembly has an elastomer disposed between the two sockets, a threaded rod, and a knob. The threaded rod passes through the two sockets and the elastomer, and is mounted with the knob.

What is claimed is: 
     
         1 . A power twister with adjustable resistance, the power twister comprising:
 a first elastic component made of a rod rolled up spirally, being hollow, and having two ends;   a first handle being a bar, and having
 two ends, wherein one of the two ends of the first handle is inserted into one of the two ends of the first elastic component, and is fixed with the first elastic component; 
   a first adjusting component fixed with the other one of the two ends of the first elastic component, and having
 a first socket having
 an upper surface; 
 a first through hole disposed through the first socket; and 
 a first toothed portion having multiple teeth protruding on the upper surface of the first socket and surrounding the first through hole; 
 
   a second elastic component made of a rod rolled up spirally, being hollow, and having two ends;   a second handle being a bar, and having
 two ends, wherein one of the two ends of the second handle is inserted into one of the two ends of the second elastic component, and is fixed with the second elastic component; 
   a second adjusting component fixed with the other one of the two ends of the second elastic component, and having
 a second socket having
 a lower surface; 
 a second through hole disposed through the second socket; and 
 a second toothed portion having multiple teeth protruding on the lower surface of the second socket, surrounding the second through hole, and engaged with the first toothed portion of the first adjusting component; and 
 
   a positioning assembly having
 an elastomer disposed between the first socket and the second socket; 
 a threaded rod passing through the first through hole of the first adjusting component, the elastomer, and the second through hole of the second adjusting component; and 
 a knob having
 a threaded hole screwed with the threaded rod. 
 
   
     
     
         2 . The power twister with adjustable resistance as claimed in  claim 1 , wherein
 the first socket has
 a first groove disposed on the upper surface of the first socket; and 
 the first through hole disposed through a bottom portion of the first socket and communicating with the first groove; 
   the second socket has
 a second groove disposed on the lower surface of the second socket; and 
 the second through hole disposed through a top portion of the second socket and communicating with the second groove; and 
   the elastomer is disposed between the first groove and the second groove.   
     
     
         3 . The power twister with adjustable resistance as claimed in  claim 1 , wherein the other one of the two ends of the first handle is sheathed with a sheath, and the other one of the two ends of the second handle is sheathed with another sheath. 
     
     
         4 . The power twister with adjustable resistance as claimed in  claim 2 , wherein the other one of the two ends of the first handle is sheathed with a sheath, and the other one of the two ends of the second handle is sheathed with another sheath. 
     
     
         5 . The power twister with adjustable resistance as claimed in  claim 1 , wherein the first handle and the second handle are each respectively a bended bar. 
     
     
         6 . The power twister with adjustable resistance as claimed in  claim 2 , wherein the first handle and the second handle are each respectively a bended bar. 
     
     
         7 . The power twister with adjustable resistance as claimed in  claim 3 , wherein the first handle and the second handle are each respectively a bended bar. 
     
     
         8 . The power twister with adjustable resistance as claimed in  claim 4 , wherein the first handle and the second handle are each respectively a bended bar.
