ABSTRACT:
A portable pneumatic tool includes a housing composed of two symmetric half shells or several partially cut-away shells; an air inlet module unit, a valve actuating module unit and an operating (or functioning) module unit fluidically communicated with one another and connected with flexible hoses among the module units; and a shock-absorbing unit retained between the operating module unit and the housing; whereby upon embedding or fixation of all the module units into the corresponding cavities in the shells and upon combination of the shells, a portable pneumatic tool will be instantly obtained having advantages of light weight, shock-absorbable property, easy assembly, lower production cost and convenient maintenance.
