The invention discloses an integral light manual pump which comprises a
steering wheel, a pump shaft, a pump body, plungers, an
oil distribution shaft, a cylinder body and a rear cover. The pump body and the rear cover are matched to form a pump cavity. The pump shaft is arranged in the pump cavity. The left end of the pump shaft penetrates out of the pump cavity. The
steering wheel is arranged at the left end of the pump shaft. The right end of the pump shaft is sleeved with the cylinder body. The pump shaft is in
interference fit with the cylinder body. A plurality of
plunger sleeves are arranged on the cylinder body. The front end of the
oil distribution shaft is located in the cylinder body. The plungers are located in the
plunger sleeves. A pump body oblique face is arranged in the pump body and is of a reinforcing rib structure. The pump body oblique face and the pump body are integrally formed through finish
casting. The pump body oblique face is rotatably sleeved with a
retainer plate. The front ends of the plungers are connected to the
retainer plate. The pump body is made of aluminum
alloy. The pump body of the integral light manual pump is made of aluminum
alloy, and an original all-steel structure is replaced. The pump body oblique face is of the reinforcing rib structure, so that the weight is reduced. In addition, the pump body oblique face and the pump body are integrally formed through finish
casting, the structure is compact, and the size is small.
