摘要： A machine tool with an auxiliary cushion structure includes a machine tool having a grip portion and a trigger switch mounted on the grip portion. The grip portion has a control lever pivotally mounted thereon to enable the control lever to rotate against the grip portion, so as to press the trigger switch during rotation and drive the machine tool to operate. The grip portion further has an auxiliary cushion mounted thereon and a gap is formed between the auxiliary cushion and the control lever. The auxiliary cushion has a supporting surface which is tilted upwards from one end close to the control lever to the other end. Thus no matter the control lever is pressed by the operator or released, the operator's hand can rest on the supporting surface to alleviate or ease the fatigue.

摘要： A negative pressure dust collection structure aims to be used on a power tool which is coupled with an application tool operable in a working space surrounded by a dust collection hood. The dust collection hood includes at least one flow conduction vent communicating with an airflow duct through a negative pressure enhancing duct. The negative pressure enhancing duct has a negative pressure enhancing chamber communicating with the flow conduction vent. The negative pressure enhancing chamber is formed at a cross section shrunk gradually from the flow conduction vent towards the airflow duct to increase suction of the negative pressure enhancing duct to collect dust in the dust collection hood. Moreover, the negative pressure enhancing chamber has an opening edge mating the shape of the inner side of the wall of the dust collection hood to increase covering range of the airflow.

摘要： A bidirectional cross airflow machine tool includes a housing chamber to hold a tool spindle and air inlets and air outlets at two sides thereof. The tool spindle is coupled with a balance weight member which includes a first balance weight portion and a second balance weight portion arranged in an up and down fashion so that the tool spindle generates eccentric rotation against the machine tool. The first and second balance weight portions respectively have a first vane set and a second vane set. The first vane set sucks air via the air inlets at one side of the machine tool during rotation of the tool spindle. The air is transmitted from the first vane set to the first and second balance weight portions, and then is discharged via the second vane set through the air outlets at another side of the machine tool to form cross cooling airflow.

摘要： A dust proof structure for a machine tool includes a flow guiding element located therein. The machine tool includes a housing chamber to hold a spindle and the flow guiding element. The housing chamber has an air intake section and an air discharge section communicating with the air intake section. The machine tool further has an air inlet communicating with the air intake section and an air outlet communicating with the air discharge section. The spindle is coupled with an action member outside the air outlet. When the spindle drives the action member to operate, the flow guiding element introduces external air through the air inlet to the air intake section, and directs the air to the air discharge section to be discharged towards the action member. Hence dust generated by the action member during operation of the machine tool does not enter the machine tool through the air outlet.

摘要： A machine tool with a heat conduction structure comprises a machine tool and a heat dissipation seat installed on the machine tool. The machine tool has a handle. The handle has an accommodation space accommodating a circuit board and having an opening at one end. The heat dissipation seat has a heat dissipation member arranged on the opening and a carrying member connected with the heat dissipation member and extended to the accommodation space. The carrying member carries the circuit board, contacts heat sources of the circuit board, and conducts heat to the heat dissipation member. As the machine tool is exempted from forming heat dissipation holes on the handle, the present invention can effectively prevent dust from entering the handle and damaging the circuit board. Further, the present invention can dissipate heat generated by the circuit board and maintain normal operation of the circuit board and the machine tool.
