Intake and exhaust guide device for pneumatic tool

Abstract

An intake and exhaust guide device for pneumatic tool comprises mainly a handle furnished with an intake passage and an exhaust passage, of which each outer end is furnished with a screw hole for directly or indirectly connected with an connector of an intake tube or an exhaust tube; the two connectors of the pneumatic tool are connected respectively with two pressure tubes fastened together in parallel; one of the two pressure tubes is connected with an output end of the compressed air, while the other pressure tube is connected with a muffler; during the pneumatic tool being operated, the compressed air can be exhausted simultaneously without having any exhaust noise as a result of the two pressure tubes being fastened together in parallel.

1 . An intake and exhaust guide device for pneumatic tool comprising:
 a pneumatic tool including a handle with a cock and a body; one end of said body furnished with a tool assembly; said handle having an intake passage and an exhaust passage therein; said intake passage extended from inner passage to a screw hole on outer end thereof;   a first screw hole furnished in one end of said handle; said first screw hole being connected with an intake connector via a replaceable part, or connected directly with said intake connector; said screw hole having a suitable diameter extended to one end of a valve in said handle;   a second screw hole furnished in one end of said handle; said second screw hole being connected with an exhaust connector via a replaceable part, or connected directly with said exhaust connector; said screw hole having a suitable length extended to said exhaust passage;   two pressure tubes fastened together in parallel mounted with a fastener at one end thereof, and said two pressure tubes being separated from said fastener, and each of them connected with a connector; other end of said two pressure tubes also being separated, in which one intake end of said pressure tube connected with a three-way connector, and one exhaust end of said pressure tube connected with a muffler via a connector.   
   
   
       2 . An intake and exhaust guide device for pneumatic tool as claimed in  claim 1 , wherein said two pressure tubes are separated at one end thereof, and one separated pressure tube in an exhaust system is connected with a three-way connector.
