A pneumatic tool comprises a housing, a cylinder and a pneumatic assembly. The housing includes a compartment, an air entrance channel interconnecting with the compartment, and an air exit channel interconnecting with the compartment. The air exit channel includes an air incoming end, an air outgoing end, and a flow-guiding incline disposed on one side of the compartment, which faces the cylinder, and connected with the rim of the air exit channel partially or completely. The cross section of the air incoming end is larger than the cross section of the air outgoing end. The air incoming end guides the high-speed and high-pressure air to the air exit channel to increase the flow rate at which the high-speed and high-pressure air flows out of the air exit channel. Thereby is solved the operational abnormalities caused by that the conventional pneumatic polishing-grinding machine cannot fully exhaust high-speed and high-pressure air.
A pneumatic tool, comprising a housing, a cylinder and a pneumatic assembly, wherein the housing includes a compartment, an air entrance channel interconnecting with the compartment, and an air exit channel interconnecting with the compartment, and wherein the air exit channel includes an air incoming end and an air outgoing end, and wherein the cylinder includes an air chamber for accommodating the pneumatic assembly, an air inlet hole interconnecting with the air chamber and disposed corresponding to the air entrance channel, and an air outlet hole interconnecting with the air chamber and the compartment, and wherein the pneumatic tool is characterized in that the air exit channel includes a flow-guiding incline disposed on one side of the compartment, which faces the cylinder, and connected with the entire rim or a part of the rim of the air exit channel, and that the cross section of the air incoming end is larger than the cross section of the air outgoing end.
