Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and cannot be construed to the utility model
Limitation.
As shown in Figure 1, the embodiments of the present invention provide a kind of ratchet spanner final vacuum structure, comprising: shell 1,
One end of the shell 1 is connected with working head 2, and operator holds and rotates fastener using working head 2 after shell 1,
The switch that air flue 3, the air motor 4 in the air flue 3 and the control air flue 3 open and close is provided in the shell 1
The output end of component 5, the air motor 4 is connect by reduction gear section 6 with working head 2, and 4 output power of air motor is given
Working head 2 realizes job step, one end away from the air motor 4 of the air flue 3 equipped with air intake assembly 7, it is described into
Exhaust passage is formed on pneumatic module 7, operator opens air flue 3, pressure-air passes through by finger push switch component 5
Air intake assembly 7 enter air motor 4 in, blow blade drive rotor rotation, and after through tail portion exhaust passage discharge, thus gram
Clothes are existing in the art, and fugitive dust problem caused by front exhaust structure does not influence operator's usage experience.
Further, the air intake assembly 7 includes inlet suction port 8 and bloop 9, and the inlet suction port 8 includes connector
The axial direction of main body 10 and the stud 11 for being fixed on described 10 one end of adapter body, stud 11 and adapter body 10 is coaxially passed through
It wears, so that pressure-air is passed through, in the present embodiment, bloop 9 is designed as cyclic structure, and 9 snare of bloop is in described
On stud 11, inlet suction port 8 is fixedly connected by stud 11 with shell 1, while the abutting of bloop 9 being fixed on shell 1, institute
Bloop 9 is stated equipped with several exhaust holes 12 to form the exhaust passage, the air-flow in air flue 3 is dispersed by exhaust hole 12
It is discharged after reduction.
Further, to further increase noise elimination effect, several exhaust holes 12 are with the stud 11 for center ring
Shape is spaced apart.
Further, several exhaust holes 12 form the first ring and the second ring of radial separations, the first ring and second
