Embodiment Construction

[0019] as seen from Figure 1 to Figure 5 It can be seen that the present invention comprises an outer housing 11 , a motor housing 21 , a switch 31 and a switch 41 .

[0020] The outer casing 11 has a receiving space 12 , two opposite through holes 13 and a handle 14 . The handle 14 has an air inlet channel 141 and an air inlet channel 142 . An air inlet passage 141 is formed protruding from the underside of the nozzle 143 of the handle 14 to be connected to a compressed air pipe. The air outlet channel 142 forms a plurality of air outlet openings 144 on the underside of the handle 14 .

[0021] The motor housing 21 is an outer housing 11 in the receiving space 12 which accommodates the motor (not shown) inside and has a receiving recess 22 on the bottom side on the inner wall with a forward rotating air inlet channel on one side 23 and a Rückwärtsdreh-connection air inlet duct 24, which is connected to the engine. When compressed air enters through the forward rotation i...

Abstract

The invention discloses an impact wrench with an improved change-over switch. The change-over switch comprises a shell (11), a motor shell (21), a switch (31) and a change-over switch body (41). The change-over switch body comprises a pushing rod (43) and a change-over valve (42). The pushing rod (43) and the change-over valve (42) are connected with each other in the horizontal direction. The axial direction of the change-over valve is perpendicular to the axial direction of the switch, thus the impact wrench has a change-over function, and a handle (14) is not arranged additionally.

Description

technical field [0001] The invention relates to an impact wrench, in particular an impact wrench having an improved switch. Background technique [0002] Will Figure 8 and Figure 9 A conventional impact wrench is shown, the upper end 71 of the lever in the handle 7 is placed to receive the air intake valve 72 , which is closed by a valve sleeve 73 . The valve sleeve 73 has a forward rotation air opening 731 and a reverse rotation air opening 732 . The intake valve 72 has a forward rotation air inlet 721 corresponding to a forward rotation air opening 731 and a reverse rotation air opening 732 . and counter-rotating air inlet 722. The intake valve 72 is rotated relative to the valve sleeve 73 by the switch lever 74 . When the air suction valve 72 of the forward rotation air inlet 721 is aligned with the valve sleeve 73 of the forward rotation air opening 731, the impact wrench rotates forward. When the counter-rotating air inlet 722 of the intake valve 72 has the valve...
