Abstract
A pneumatic tool including a cylindrical main body in which a speed-adjusting section is disposed and a hollow barrel-shaped plastic sleeve fitted around the main body. The speed-adjusting section has an end section which is radially connected with an inner annular wall. Two opposite pin seats are disposed on one side of the plastic sleeve. Each pin seat has a pinhole. A pin member is fitted through two lugs of a press lever and the pinholes of the pin seats to pivotally connect the press lever with the plastic sleeve. After the plastic sleeve is fitted around the main body, an annular receiving space is defined between an outer circumference of the annular wall of the main body and an inner circumference of the plastic sleeve. The annular receiving space is not occupied by any other component so that an annular muffling member can be accommodated in the annular receiving space. In addition to the original annular muffling member, another annular muffling member with the same size and specification can be further installed in the rear end of the plastic sleeve to enhance the muffling effect.
