What is claimed is: 
     
         1 . A mounting device configured to mount an air conditioner to a structure, the mounting device comprising:
 a fixing frame configured to support the air conditioner;   a moving frame configured to be movable up and down relative to the fixing frame;   a rail provided on the moving frame, configured to be movable up and down together with the moving frame, and having teeth extending along a direction of movement of the moving frame;   a moving shaft provided on the fixing frame, configured to be movable in a first direction toward the teeth and in a second direction away from the teeth, the moving shaft including a locking protrusion formed at a first end thereof and configured to engage with the teeth;   a handle provided at a second end of the moving shaft and configured to move the moving shaft in the second direction; and   a handle locking part configured to lock the handle to restrict movement of the moving shaft in the first direction while the moving shaft is in a state of having been moved in the second direction by the handle.   
     
     
         2 . The mounting device of  claim 1 , further comprising:
 a spring configured to elastically bias the moving shaft in the first direction.   
     
     
         3 . The mounting device of  claim 2 , wherein, in a state in which the handle locking part does not fix the handle, the locking protrusion of the moving shaft is maintained in engagement with the teeth of the rail by the spring. 
     
     
         4 . The mounting device of  claim 2 , wherein the moving shaft is further configured to be in:
 a first state in which the locking protrusion is engaged with the teeth;   a second state in which engagement between the locking protrusion and the teeth is released; or   a third state in which engagement between the locking protrusion and the teeth is released and the handle locking part fixes the handle to restrict movement in the first direction.   
     
     
         5 . The mounting device of  claim 4 , wherein the moving shaft is further configured to:
 be switched from the first state to the second state when a predetermined force is applied to the handle in the second direction, and   be switched from the second state to the first state when the predetermined force is removed from the handle.   
     
     
         6 . The mounting device of  claim 4 , wherein the second state of the moving shaft is a state in which the moving shaft has been moved in the second direction from the first state. 
     
     
         7 . The mounting device of  claim 4 , wherein the second state of the moving shaft is a state in which the moving shaft has been moved in the first direction from the third state. 
     
     
         8 . The mounting device of  claim 1 , further comprising:
 a case detachably coupled to the fixing frame and configured to accommodate at least a portion of the moving shaft,   wherein the handle locking part is formed on the case.   
     
     
         9 . The mounting device of  claim 1 ,
 wherein one of the handle and the handle locking part includes a locking protrusion, and   wherein other end of the handle and the handle locking part includes a locking groove corresponding to the locking protrusion.   
     
     
         10 . The mounting device of  claim 1 , wherein the handle locking part further includes an inclined surface inclined upward along the second direction. 
     
     
         11 . The mounting device of  claim 10 , wherein the handle is further configured to be movable on the inclined surface, and to be caught and fixed by the handle locking part by being separated from the inclined surface in the second direction. 
     
     
         12 . The mounting device of  claim 1 ,
 wherein the rail includes:
 a first section in which the teeth are formed, and 
 a second section other than the first section, the second section being arranged along a moving direction of the moving frame with respect to the first section, and 
   wherein the second section is configured to prevent the moving frame from being separated from the fixing frame by moving upward with respect to the fixing frame.   
     
     
         13 . The mounting device of  claim 12 , wherein the second section includes:
 a receiving portion configured to receive at least a part of the locking protrusion; and   a supporting portion provided below the receiving portion and configured to interfere with a lower end of the locking protrusion.   
     
     
         14 . The mounting device of  claim 1 ,
 wherein the teeth has a tapered shape that narrows upward, and   wherein the moving frame is further configured to be movable upward and restricted from moving downward when the locking protrusion is engaged with the teeth.   
     
     
         15 . The mounting device of  claim 14 , wherein an inclination angle of the teeth with respect to a horizontal direction is 50 degrees. 
     
     
         16 . An air-conditioning apparatus comprising:
 an air conditioner; and   a mounting device configured to mount the air conditioner,   wherein the mounting device includes:
 a first frame part configured to support the air conditioner, 
 a second frame part extending upward from one side of the first frame part, 
 a third frame part extending in parallel with the second frame part from other side of the first frame part, 
 a fourth frame part connecting the second frame part and the third frame part, constituting a fixing frame; 
 a moving frame including a fifth frame part configured to be movable relative to the second frame part and a sixth frame part configured to be movable relative to the third frame part; 
 a rail disposed on at least one of the fifth frame part and the sixth frame part of the fixing frame and including teeth; 
 a moving shaft disposed on the fourth frame part, configured to be movable along an extending direction of the fourth frame part, and including a locking protrusion configured to engage with the teeth; and 
 a handle configured to move the moving shaft. 
   
     
     
         17 . The air-conditioning apparatus of  claim 16 , wherein the moving shaft is configured to have a first state in which engagement between the locking protrusion and the teeth is released by applying a predetermined force to the handle, and a second state in which the locking protrusion and the teeth are engaged again by removing the predetermined force from the handle.
