The purpose of this utility model is at the deficiencies in the prior art, and a kind of novel pressure pump is provided, its design science, easy for operation, and pressure release control is effective.

For achieving the above object, the utility model adopts following technological scheme: a kind of novel pressure pump, it comprises handle, the pump housing, pressure gauge, conduit, connecting head, the pump housing is the hollow columnar housing, handle is connected with an end of the pump housing, handle is provided with pressure relief device, the handle axle center is passed and is provided with the push rod that the surface has screw thread, the tail end of push rod is connected with knob, place the push rod head end in the pump housing to be connected with piston, the other end of the pump housing is connected with connecting head by conduit, and pressure gauge is installed in the upper end of the pump housing and conduit joint, is in outside the pump housing.

Described pressure relief device by handle and about the trigger, facing, the lid that switch constitute, in the facing mounting hole spring is housed, the facing bottom is provided with the screw thread with the push rod engagement with screw thread, and trigger cooperates with facing by lid, screw in the containing groove of handle; Trigger left and right sides switching controls is advanced to cooperate with facing and pressure is increased progressively have the pressure release function concurrently;

Described connecting head is connected with conduit by hose coupling, is provided with seal ring, transparent cover body between connecting head and the hose coupling;

The tail end of described push rod is connected with knob by screw;

Described conduit is a high-pressure conduit;

Described trigger upper surface is provided with a plurality of friction particles and forms attrition surface.

The utility model beneficial effect is: handle is provided with pressure relief device, the handle axle center is equipped with the push rod that the surface has screw thread, the tail end of push rod is connected with knob, place the push rod head end in the pump housing to be connected with piston, the other end of the pump housing is connected with connecting head by conduit, pressure relief device is made of trigger, facing, lid, in the facing mounting hole spring is housed, the facing bottom is provided with the screw thread with the push rod engagement with screw thread, its design science, easy for operation, pilot pressure size well during pressure release, the pressure relief press button mounting point is beneficial to operation technique.
