1. A spraying apparatus for discharging the contents of a valve-equipped aerosol can comprising:

  • an elongated, hollow tube having a front and rear end;

    a front housing fixed to the tube at the front end, the front housing including a can holder comprising a hollow cylinder sized to receive an aerosol can;

    a bell crank pivotally mounted in the front housing;

    a trigger rod fixed to a first arm of the bell crank, and mounted within the front assembly and tube for sliding longitudinal movement, such movement causing rotation of the bell crank;

    an actuator rod fixed to a second arm of the bell crank and mounted within the first housing for longitudinal movement between a discharging position, wherein the actuator rod pushes the can valve, and a non-discharging position;

    a biasing spring fixed between the trigger rod and a retaining wall in the front housing, which biases the trigger rod to a position where the actuator rod is in the non-discharging position;

    a rear housing mounted to the rear end of the tube the rear housing including a grip portion;

    a trigger disposed within the rear housing and connected to the trigger rod for reciprocating horizontal movement between a discharging position, wherein the actuator rod is in the discharging position, and a non-discharging position;

    a locker rotationally mounted in the rear housing and rotatable between a non-locking position, wherein only horizontal movement of the trigger is allowed, and a locking position wherein horizontal and vertical movement of the trigger in the discharging position is allowed; and

    a locking land disposed within the rear housing for frictionally receiving a front surface of the trigger when it is moved vertically from the discharging position, the biasing spring biasing the trigger into engagement with the locking land and thus maintaining the trigger in the discharging position.
