  • Patent number: 10005098
    Abstract: A power operated dispensing tool includes a housing having a material packing receiving space, and a rod disposed within and movable relative to the housing and having a plunger head that is disposed in the material packing receiving space. The rod is operably coupled to a power transmitting mechanism so as to make a forward movement driven by a power of a motor through the power transmitting mechanism to discharge a dispensing material in the material packing receiving space. The rod has an initiating portion disposed to actuate a sensing member in the housing to deactivate the motor when the rod is moved forwardly to a first stop position. The rod can be moved manually to a second stop position to project the plunger head outwardly so as to permit a plunger kit to be attached thereto.

  • Patent number: 8646657
    Abstract: An electric caulking gun has a body and an actuating assembly. The body has a pushing shaft, a motor, a gearbox, a transmission device, a circuit board and a switch. The gearbox has a sun gear with multiple mounting slots. The actuating assembly is mounted in the body, is connected to the switch and engages the sun gear and has a connecting arm, a linking arm, an actuating element, an oscillating arm and a pressing button. The connecting arm is pivotally connected to the switch. The linking arm is connected to the connecting arm. The actuating element is mounted in the body, selectively engages one of the mounting slots and has a wedge mount and an engaging block. The oscillating arm is connected to the body and is connected to the connecting arm. The pressing button is movably mounted in the body and is connected to the oscillating arm.

  • Patent number: 8573450
    Abstract: An electrical caulking gun has a gun body and a clutching device. The clutching device has a clutching switch, a linking lever, a clutching block and a block spring. The clutching switch is mounted on the gun body and has a pressed segment and a pushing segment having an inclined pushing surface. The linking lever is pivotally mounted in the gun body and has an abutting end and a pushing end. The abutting end abuts with the pushing surface of the clutching switch. The clutching block has an inclined pushed surface and an engaging rod. The engaging rod detachably engages a transmission device of the caulking gun. The block spring provides a force to push the engaging rod on the clutching block to engage the transmission device.
