         [0019]    With reference to  FIGS. 1 ,  2 , and  3  shown respectively as a partial 3D exploded perspective view of a lavatory faucet with two lever handles, a partial 3D exploded perspective view of a water inlet passage, and a 3D exploded view of a quick release joint unit, the lavatory faucet with two lever handles mainly comprises a faucet body  60 , two valves  10 , two quick release joint units  20 , two watertight units  30 , two water pipes  40 , and two joint units  50 . 
         [0020]    A gateway  61  is formed in the faucet body  60 , and a water inlet  62  and a water outlet  63  are formed at the outside of faucet body  60  that is opposite to two ends of the gateway  61 . 
         [0021]    Each of the two valves  10  is connected to a water outlet passage  11  and a water inlet passage  12 . The water outlet passages  11  are connected to a water inlet  62  of the faucet body  60 . The outsides of water inlet passages  12  are formed with threads  123 , the water passages  12  are concave and then formed with a joint slot  121 . A shift limit slot  122  is formed around the inner circumference of each of the joint slots  121 . 
         [0022]    The quick release joint unit  20  is correspondingly arranged in the joint slot  121  and comprises an outer ring  21  and a locking jaw  22 . The outer ring  21  is set around the outside of locking jaw  22 , and the inner circumferential side of outer ring  21  is an inclined plane  211 . Further, the outer circumference of outer ring  21  is formed with several protruding clamping slices  212  spaced at a distance of intervals and fixed in the shift limit slot  122 . The locking jaw  22  has four chucks  221 . Next, each of the outsides of chucks  221  is formed with a flange  222 , and several shift limit slices  223  opposite to the flanges  222  are formed at the inner sides of chucks  221 . A shift limit ring  224  is provided at the bottom side of locking jaw  22 . The outer ring  21  pivots between the flange  222  and the shift limit ring  224 . 
         [0023]    The watertight units  30  are watertight O-rings that are provided between the joint slots  121  and the quick release joint units  20 . 
         [0024]    The water pipes  40  are plastic hoses one end of each of which is arranged in the quick release joint units  20 .

Each of the outsides of joint units  50  is further formed with outer threads  52  and spirally joined with a blockage unit  53 , a screw nut  54 , and the joint units  50  are used to fix the faucet to washbasin. 
         [0026]    With reference to  FIGS. 1 and 2 , when the faucet is installed, only the water pipe  40  is required to pass through the quick release joint unit  20  and the watertight unit  30 , thereby the connection procedure being finished. When the water pipe  40  is outwards pulled by a force, because the outer ring  21  is fixed into the joint slot  121 , the locking jaw  22  that is subject to the friction withdraws from the outer ring  21  with the water pipe  40 . Being subject to the shift limit of inclined plane  211  on the outer ring  21 , the flange  222  on the chuck  221  makes the chuck  221  cause a force of grip, which makes the shift limit slice  223  in the chuck  221  fix the water pipe  40  and thus makes the water pipe  40  not fall off; for example, to remove the water pipe  40 , the locking jaw  22  is upwards pushed to prevent the locking jaw  22  from withdrawing with the water pipe  40  and thus eliminate the force of grip that is caused by the chuck  221  on the water pipe  40 . Thus, the pipeline of faucet may quickly removed without any tool. The water pipe  40  is made of plastics so that the lead content in water may be effectively lowered to increase the quality of water for the security of water use.
