A control device including a first shell; a battery pack mounting part; a first control unit, which is provided in the first shell and is used for cutting off power transmission from a battery pack to an electric power tool when the battery pack is abnormal; a first user operation unit, which is arranged on the first shell and is operated by a user to control the electric power tool; and a first interface, electrically connected to the first user operation unit. An electric power tool system comprises the control device and the electric power tool. The control device can be adapted to different types of electric power tools, and the control device is not provided with a control portion used for adjusting working parameter of the electric power tool, such that the control device can more flexibly match an upgraded new electric power tool.

Control device and electric power tool system

A portable cutting tool includes a blade and a motor for driving the blade to rotate. The motor has a motor output shaft. A guard assembly includes an upper guard and a lower guard which is used for receiving the motor. A base is connected to the upper guard. The base further includes a front portion connected to the upper guard, a rear portion extending longitudinally, and a gripping portion disposed between the front portion and the rear portion. The blade shaft is perpendicular to the motor output shaft.

Portable cutting tool

The present embodiment discloses a hand-held tool and a clamping device thereof. The clamping device of a hand-held tool includes: a mounting base; a clamping unit configured to fasten a working tool in an axial direction; and an operation assembly, including an operating member and a driving member, where the operating member is capable of performing compound motion relative to the mounting base, and the operating member is operable to drive the driving member to selectively mate with and disengage from the clamping unit. In this way, the hand-held tool of the present embodiment has the clamping device. By way of compound motion, not only comfort of operation can be achieved, but also parts can be saved, thereby making the structure simpler and more reliable.

Hand-held tool and clamping device thereof

An oscillatory power tool that is capable of using various types of cutting tools is disclosed. The power tool includes an output shaft for mounting one of the cutting tools and driving the cutting tool in an oscillating rotary motion. An end of the output shaft has a driving section for engaging with a securing section of the cutting tool. The power tool further includes a fastener connected to the output shaft at the end and connectable to the securing section of the cutting tool for fastening the cutting tool to the end of the output shaft. The driving section has a fitting surface for contacting a surface of the securing section. Through a close fit between the friction surface and the surface of the securing section, the power tool can be connected with different types of cutting tools, which greatly improves the universality and convenience of the power tool.

Multifunctional machine

A combination of electric tools includes a first electric tool and a second electric tool respectively having an independent power supply. The second electric tool starts working automatically responding to the startup of the first electric tool. Thereby the second electric tool starts automatically after the first electric tool is started to operate by a user without an extra operation of the user, which is convenient to the user.

Combination of electric tools and start method thereof

A worktable including an opening and an upper surface for supporting a workpiece; a supporting unit for supporting the worktable; a cutting mechanism mounted on a lower surface of the worktable and contained within the supporting unit including: a motor for outputting a rotation motion; a reciprocating rod driving a saw blade moving reciprocately through the opening; a motion conversion mechanism converting the rotation motion of the motor into a reciprocating motion of the reciprocating rod; and a saw blade clamp for clamping and releasing the saw blade; the saw blade clamp including an operating element which is disposed on the external surface of the worktable or the supporting unit.

Cutting machine with blade clamp

A vegetation pruning device includes a cutting element; a guide bar for supporting the cutting element, the guide bar having a guide bar plane, the guide bar being pivotable in the guide bar plane about a fixed axis; a motor having a motor shaft for rotatably driving the cutting element; a motor housing for receiving the motor; a guiding mechanism connected to the motor housing, the guiding mechanism having a longitudinal axis; a handle assembly operable to move linearly along the longitudinal axis; and a transmission device for connecting the handle assembly to the guide bar through, the transmission device converting a linearly movement of the handle assembly to a pivoting movement of the guide bar, the cutting element thereby approaching or withdrawing from a workpiece to be sawn.

Vegetation trimmer

The present invention relates to a clamping device comprising an elongate support structure carrying a fixed jaw and a movable jaw and an advancing clamping mechanism mounted on the support structure for advancing the movable jaw toward the fixed jaw in a longitudinal direction. The clamping device further comprises a transportation mechanism for convenient transportation.

Clamping device

An electric power tool including a housinghaving a motive power, and a tool holdercoupled to said motive powerfor receiving a cutting tool, a base platehaving an openingthrough which said cutting tool extends, said base platebeing adjustable mounted to said housing by guide arms, the position of said cutting tool being varied by adjusting the position of the base platerelative to the housing, said tool holderbeing able to extend through the openingof the base platefor easier access to the tool holder, a slave pinin the housingadapted to engage a recess in the tool holder to lock the tool holderagainst rotation to enable single-handed removal of a tool from the tool holderfrom above a tool table, such as a router table.

Electric power tool

A circular saw including a frame, a drive means mounted to the frame coupled to a planar saw blade for rotation about a drive axis within a cutting plane and a base pivotably mounted to the frame about a first axis substantially parallel to the cutting plane and a second axis which is generally substantially parallel to the drive axis. In one aspect, the relative pivotal movement of the frame about the first axis is determined by a trim adjuster including disengageable position locator which is operable to provide a plurality of predetermined discrete engaged positions and a locking means for locking the position of the frame relative to the base over a continuous range of settings. The invention also provides a mounting assembly including a course adjustment means and a fine adjustment means to determine the pivotal movement of the frame about the second axis relative to the base.
