20150097641 | SWITCH ASSEMBLY FOR ELECTRIC TOOL - A switch assembly includes a circuit board mounted in the housing of an electric tool and carrying multiple magnetic sensor components, a first button having hooks slidably coupled to the circuit board and a press portion exposed to the outside of the housing for pressing by a user and a first magnetic member mounted at the press portion and movable with the first button relative to the housing to induce and change the magnetic flux of one magnetic sensor component, and a second button mounted in the housing and movable back and forth relative to the housing and carrying a second magnetic member that is movable with the second button to induce and change the magnetic flux of the other magnetic sensor component. | 04-09-2015 |
20150096775 | HYDRAULIC PULSE TOOL HAVING A SHUTOFF FUNCTION AND SHUTOFF CONTROL METHOD USED IN SAME - A hydraulic pulse tool includes a power supply unit, a drive unit electrically connected to the power supply unit, a hydraulic pulse torque generating unit coupled to the drive unit and rotatable by the drive unit to produce impacts for causing the drive to produce an electric current change, and a control unit for judging the electric current change and controlling the operation of the drive unit subject to the judgment result. Subject to the above-stated technical characteristics, the hydraulic pulse tool, in addition to the shutoff function, can reduce errors in judgment and achieve multi-stage torque output control. | 04-09-2015 |
20150040373 | ELECTRIC RIVETER CAPABLE OF RIVET PRE-PULLING AND OPERATION METHOD FOR THE SAME - An electric riveter capable of rivet pre-pulling includes an operating unit, a controlling unit, a driving unit, and a clamping unit. The controlling unit controls the driving unit according to the way in which a user operates the operating unit, the clamping unit is driven by the driving unit to move between an initial position, a pre-pulling position, and a severing position. The operation method for the electric riveter entails: providing a rivet when the clamping unit is at the initial position; operating the operating unit in a first operation mode to move the clamping unit to the pre-pulling position and clamp the rivet; and operating the operating unit in a second operation mode to move the clamping unit to the severing position and sever the rivet. Accordingly, the rivet is prevented from falling off during the operation process, thereby enhancing ease of use of the electric riveter. | 02-12-2015 |
20100139067 | RIVETING UNIT FOR ELECTRIC RIVET GUN - A riveting unit is assembled with an electric rivet gun, including a transmission unit, a clamping jaw having a locating portion driven by the transmission unit to be moveable between a first position and a second position, a first sensor detecting whether the locating portion of the clamping jaw is located at the first position, and a second sensor detecting whether the locating portion of the clamping jaw is located at the second position. When the locating portion of the clamping jaw is located at the first position, a blind rivet can be installed in the clamping jaw, and when the locating portion of the clamping jaw is located at the second position, the blind rivet can be ejected, and meanwhile the second sensor can allow the transmission unit to stop the movement of the clamping jaw, thereby preventing the clamping jaw from moving backwards excessively. | 06-10-2010 |
20100139066 | RIVETING TOOL WITH A RIVET ROD EXPELLING FUNCTION - A riveting tool with a rivet rod expelling function is disclosed to include a tool body having a base and a grip extended from the base. The base has a rivet passage defined therein and an opening located on the peripheral wall thereof in communication with the passage and adjacent to the grip for quick discharge of each broken rivet rod during the riveting operation. | 06-10-2010 |
20090242225 | PNEUMATIC TOOL WITH NOISE REDUCTION FUNCTION - A pneumatic tool capable of reducing noise includes a housing having an air intake passage and an exhaust passage, a pneumatic unit mounted in the housing, and an air-guiding member detachably mounted in the exhaust passage. The air-guiding member has an end plate with at least one hole and a lateral wall mounted on a periphery of the end plate to define an air-guiding chamber therebetween and extending divergently from the end plate and provided with at least one hole. Thus, when compressed air goes through the pneumatic tool from the air intake passage to the exhaust passage, it goes into the air-guiding chamber through the holes of the end plate and the lateral wall, and then goes out of the housing. | 10-01-2009 |
