Claim 0:
1. An air compressor being received in an accommodation box and comprising a body, and the body including:
multiple positioning orifices which are a first positioning orifice and a second positioning orifice;
a cylinder connected on the body and communicating with an air storage holder;
a motor fixed on the body, a small gear being received in the first positioning orifice, and a connection seat of the motor being accommodated in the first orifice, wherein the motor further includes two dissipation holes symmetrically formed on an outer wall of a casing thereof and configured to circulate airs and to dissipate heat from the motor, and the motor includes a magnetic coil fitted thereon and made of metal material so as to guide magnetism efficiently, when the motor operates;
a transmission mechanism actuating a piston to move in the cylinder reciprocately so as to produce compressed airs;
wherein the motor includes two locking extensions symmetrically extending from the magnetic coil which is fitted on the motor and configured to engage the motor with the body, each of the two locking extensions has a neck formed on a distal end thereof, wherein a width of each of the two necks is less than a width of the respective one of the two locking extensions, and each of the two necks has a wing extending from a distal end thereof, wherein a width of each of the two wings is equal to the width of the respective one of the two locking extensions, and the body further includes two receiving grooves defined on two sides thereof and corresponding to the two wings of the two locking extensions, wherein the two receiving grooves are a first receiving groove and a second receiving groove, and the two wings are located at the two receiving grooves of the body, wherein a pressing tool is configured to press the two wings into the first receiving groove and the second receiving groove of the two receiving grooves to form a first bent tab and a second bent tab, and the first bent tab and the second bent tab are pressed into the two receiving grooves, hence the motor is fixed on the body securely without using any screws.
