Abstract: A laser level with adjustable laser projection line comprises a support bracket, a housing, a switch, a laser generator which project a fanned laser beam to the surface of the work piece to form a line, and wherein a rotating mechanism is coupled to rotate the laser generator thereby causing rotation of the line. There is also a positioning device to position the laser level on an arbitrary surface.

Abstract: A device for adjusting a foot plate of a saw. The device includes a locking member with a fastener connected therewith for fastening the foot plate to a housing of a saw. A rotatable sleeve is connected to the locking member for rotating the locking member. A rotatable actuator assembly is pivotally connected to the rotatable sleeve for turning the rotatable sleeve. The rotatable sleeve and locking member can be engaged or disengaged with each other by effect of a biasing member or spring therebetween. Therefore, when the rotatable sleeve and locking member are engaged with each other, the rotatable actuator assembly can be turned to rotate the rotatable sleeve, and the bolt which is fixed to the locking member is rotated consequently to adjust the tightness or looseness between the foot plate and housing of a saw.

Abstract: A mixer paddle for a mixer to mix particulate substances is provided including a main shaft for transferring rotation that acts thereon, at least one mixing shaft eccentric from the main shaft, and at least one paddle member mounted on the at least one mixing shaft and being freely rotatable thereabout. With such a structure, during the operation, the paddle member rotates around the main shaft and synchronously rotates around the mixing shaft due to the resistance produced by the particulate substances, so that power consumption is decreased, and mixing efficiency is improved.

Abstract: The present invention relates to a power tool with battery power supply comprising a main body and a detachable battery package which are connected with each other via a securing frame and a locking assembly. The securing frame includes a guiding device, an locking/unlocking button located on one of the main body and the battery package. An electrical connection is provided between a motor in the main body and the battery package, and includes a plurality of electrode connectors and corresponding electrode contact tabs. A mechanism for creating a non-mechanical force is located between the main body and the battery package for pushing the battery package out of the securing frame.

Abstract: The present invention discloses a power tool with a tool storage compartment. The power tool includes a housing and a tool storage compartment detachably mounted onto the outside of the housing for storing spare tools and power tool accessories. The power tool housing contains at least one guide bar and a sliding slot is disposed on a surface of the tool storage compartment acting with the housing. The guide bar and the sliding slot are engageable with each other, such that the tool storage compartment is slidable relative to the housing. The tool storage compartment and the housing respectively comprise fixing means for engaging with each other. The tool storage compartment can be automatically locked when it slides along the guide bar and reaches a predetermined position. Additionally, the tool storage compartment further includes a mechanism for fastening the tools and a device for conveniently accessing the tools.

Abstract: A line-marking device with rotatable laser disclosed in the present invention comprises a laser rotating and locating system including a fixing member and a rotating member, one of which has a gear-shaped component, and the other member of which has a component that can be engaged with the gear-shaped component, and an elastic member pressing the engaged component to the gear-shaped component. The laser-emitting device is fixedly connected to the rotating member. A straight line formed by the laser on a wall can be rotated along with the rotating member. In an effect of the elastic member and by the interaction between the gear-shaped component and the engaging component for it, a location can be obtained when the two component is rotated across a space of a tooth, so that a fan-shaped beam emitted from the laser line-marking device can not only be rotated from the 0 degree to the 360 degrees, but also be reliably located at a plurality of angles.

Abstract: An electrical plug for a power tool is disclosed. The electrical plug comprises a housing having a first end, a second end and a sidewall. The first end of the housing is connected to an electrical cord, and at least one prong protrudes from the second end of the housing. The electrical plug also includes at least one groove formed into the sidewall of the housing. The groove is provided for clasping a portion of said electrical cord.
