Transmission apparatus

Abstract

The present invention relates to a transmission apparatus, which comprises a base, a transmission module, a first protection sleeve, and a second protection sleeve. The transmission module is disposed on the base and includes a moving unit. The first protection sleeve is disposed around the outer periphery of the transmission module and on the base. One end of the second protection sleeve is covered by the first protection sleeve. The second protection sleeve is disposed around the moving unit and moves linkedly along the moving unit. Thereby, the transmission apparatus according to the present invention may protection the transmission module.

What is claimed is: 
     
         1 . A transmission apparatus, comprising:
 a base;   a transmission module, disposed on said base, and having a moving unit;   a first protection sleeve, surrounding the outer periphery of said transmission module, and disposed on said base; and   a second protection sleeve, having one end surrounding said first protection sleeve and surrounding said moving unit, and moved linkedly by said moving unit.   
     
     
         2 . The transmission apparatus of  claim 1 , further comprising a third protection sleeve, surrounding the other end of said second protection sleeve and fixed on said base. 
     
     
         3 . The transmission apparatus of  claim 2 , further comprising one or more sealing ring disposed at the overlap of said second protection sleeve and said third protection sleeve. 
     
     
         4 . The transmission apparatus of  claim 3 , further comprising one or more injection hole, being a hole and disposed at said third protection sleeve. 
     
     
         5 . The transmission apparatus of  claim 2 , further comprising a protection lid surrounding one end of said third protection sleeve and disposed on said base. 
     
     
         6 . The transmission apparatus of  claim 2 , further comprising:
 a displacement sensing rod, disposed on said base, said second protection sleeve and said third protection sleeve surrounding the outer periphery of said displacement sensing rod; and   a location sensor, disposed at said second protection sleeve, opposing to said displacement sensing rod, and said third protection sleeve surrounding the outer periphery of said location sensor.   
     
     
         7 . The transmission apparatus of  claim 2 , wherein said first protection sleeve, said second protection sleeve, and said third protection sleeve are hollow cylinders, respectively, and the axis of said first protection sleeve, the axis of said second protection sleeve, and said axis of said third protection sleeve are coaxial. 
     
     
         8 . The transmission apparatus of  claim 1 , further comprising one or more sealing ring disposed at the overlap of said first protection sleeve and said second protection sleeve. 
     
     
         9 . The transmission apparatus of  claim 8 , further comprising one or more injection hole, being a hole and passing through said first protection sleeve. 
     
     
         10 . The transmission apparatus of  claim 1 , wherein said first protection sleeve and said second protection sleeve are hollow cylinders, respectively, and the axis of said first protection sleeve opposing to the axis of said second protection sleeve. 
     
     
         11 . The transmission apparatus of  claim 1 , further comprising a transport mechanism, said transport mechanism including a carrier, a moving module, and a plurality of clipping units, said carrier disposed on said base, said moving module disposed at and moved linkedly by said second protection sleeve, said moving module moving with respect to said carrier, and said plurality of clipping units disposed on said carrier and said moving module, respectively. 
     
     
         12 . The transmission apparatus of  claim 11 , wherein said base further comprises a first base body, a second base body, and one or more fixing rod; said fixing rod is disposed between said first base body and said second base body; said moving module includes a moving platform and a moving base; said moving platform is disposed on said moving base; said moving base is disposed at and moved linkedly by said second protection sleeve; and said fixing rod passes through said moving base. 
     
     
         13 . The transmission apparatus of  claim 11 , wherein each said clipping unit includes a channel, a press member, and a push member; said press member is disposed corresponding to said channel; and said push member is against to said press member. 
     
     
         14 . The transmission apparatus of  claim 11 , wherein said plurality of clipping units are arranged in line. 
     
     
         15 . The transmission apparatus of  claim 11 , further comprising a conductive member disposed at one end of said carrier.
