The invention discloses a mechanical structure and a use method of a compact hand-held tape
winding machine. The mechanical structure of the compact hand-held tape
winding machine comprises a case mechanism, a
handle mechanism, a key regulating mechanism, a feeding mechanism, a heat dissipating mechanism, and an elastic opening expanding mechanism. The case mechanism comprises a case shell in which a motor, a fan, a key regulating module and a controller are arranged. The
handle mechanism and the case mechanism are integrally formed. A trigger unit, a
wireless communication module and a
power module are arranged inside the
machine. The case mechanism in the mechanical structure of the compact hand-held tape
winding machine is fixed at a side edge of a gearbox, thus reducing side space waste of the gearbox and providing more compact structure and small overall dimension of the whole
machine; therefore, the
machine can be manipulated and stored conveniently. An air inlet is formed in the back of the fan to draw outside air into the shell of the case mechanism; air outlets are formed in two side surfaces of the motor so as to form an
air cooling channel near the motor and the controller; the
handle mechanism and the gearbox are arranged front and back to ensure that the opening is consistent with an object approaching direction, which is convenient for an operator to make a judgement.
