     TECHNICAL FIELD 
     The application relates to the technical field of vehicle-mounted charging and relates to a vehicle-mounted charger. 
     BACKGROUND 
     A vehicle-mounted charger is an accessory which is convenient for a vehicle owner to charge electronic products at all times and places with a vehicle-mounted charging power supply. 
     As a shell of a conventional vehicle-mounted charger often protrudes out of an end surface of an inlet end of a power taking port after being inserted into the power taking port of a vehicle-mounted power supply and it is hard for a handle to better fit the shell so as to store and hide the handle because the handle and the shell of the vehicle-mounted charger are usually mounted in a separated manner, a user is unable to better seal the power taking port of the vehicle-mounted power supply via a cover body when not using the vehicle-mounted charger, and thereby, huge hidden dangers are brought to safe use of the vehicle-mounted power supply. 
     Technical Problem 
     The application is mainly intended to provide a vehicle-mounted charger to solve the technical problem that the power taking port of the vehicle-mounted power supply cannot be better sealed via the cover body under a condition of an existing vehicle-mounted charger. 
     Technical Solution 
     A vehicle-mounted charger includes a shell, a charging interface, a circuit board and a handle, where the shell is capable of being completely inserted into a power taking port of a vehicle-mounted power supply, the charging interface is embedded into a first end of the shell, the circuit board is mounted in the shell and is connected with the charging interface, the first end of the shell is provided with a locking slot, the handle is rotatably arranged at the first end and is capable of being completely moved in and clamped into the locking slot or being moved out from the locking slot via its own rotation, and the first end is an end of the shell deviated from the power taking port; the handle is provided with a first connecting portion, an axle hole passes through the first connecting portion, a connecting shaft passes through the axle hole, and two ends of the connecting shaft pass through two opposite sides of the first end. 
     The present invention has the beneficial effects: 
     As the shell is designed to be capable of being completely inserted into the power taking port of the vehicle-mounted power supply, it is ensured that the shell will not protrude out of the end surface of the inlet end of the power taking port when being inserted into the power taking port; moreover, the first end of the shell is provided with the locking slot, the handle is rotatably arranged at the first end and is capable of being completely moved in and clamped into the locking slot or being moved out from the locking slot via its own rotation, and the user is able to drive the handle to rotate via an external force, so that the handle is moved out from the locking slot when it is required to use and is completely moved in and clamped into the locking slot without protruding out of the end surface of the first end of the shell when it is not required to use, and therefore, the handle is stored and hidden conveniently. Thus, it is ensured that the user is able to better seal the power taking port by fitting the cover body and the end surface of the inlet end of the power taking port when not using the vehicle-mounted charger, thereby overcoming the potential safety hazards of the vehicle-mounted power supply in use. The handle is provided with the first connecting portion which can increase the connecting area between the handle and the first end, so that it is labor-saving and safe. Furthermore, the sense of beauty of the whole structure formed by assembling the vehicle-mounted charger and the vehicle-mounted power supply can be further enhanced.

Thus, it is ensured that the user is able to better seal the power taking port  21  by fitting the cover body and the end surface of the inlet end of the power taking port  21  when not using the vehicle-mounted charger  10 , thereby overcoming the potential safety hazards of the vehicle-mounted power supply  20  in use. The handle  500  is provided with the first connecting portion which can increase the connecting area between the handle  500  and the first end, so that it is labor-saving and safe. Furthermore, the sense of beauty of the whole structure formed by assembling the vehicle-mounted charger  10  and the vehicle-mounted power supply  20  can be further enhanced. 
     Referring to  FIG. 1  to  FIG. 3 , provided is vehicle-mounted charger  10 , specifically including a shell  110 , a charging interface  120 , a circuit board  200  and a handle  500 , where the shell  110  can be completely inserted into a power taking port  21  of a vehicle-mounted power supply  20 , the charging interface  120  is embedded into a first end of the shell  110 , the circuit board  200  is mounted in the shell  110  and is connected with the charging interface  120 , the first end of the shell  110  is provided with a locking slot  114 , the handle  500  is rotatably arranged at the first end and can be completely moved in and clamped into the locking slot  114  via its rotation or can be moved out from the locking slot  114 , and the first end is an end of the shell  110  deviated from the power taking port  21 ;
