摘要： An electrical connector configured to connect terminals of battery units in a battery pack includes a body made of an electrically conductive material, the body having at least a first body part and a second body part, and at least one terminal connection part disposed adjacent the first body part configured to connect to the terminal of the battery unit. The at least one terminal connection part includes a first connection component and a second connection component spaced apart from each other. Each of the first and second connection components includes a contact part for contacting the terminal of the battery unit, and a stem connecting the contact part to the body. The stem has a smaller cross section than the contact part. The stem is operable as a fuse configured to cut off an excessively high current.

摘要： Disclosed in the present invention are a grass-cutting robot and a control method therefor. The grass-cutting robot comprises a travelling apparatus, a motive power apparatus, a detection apparatus and a control apparatus. The travelling apparatus is configured to facilitate travel of the grass-cutting robot on a physical surface in a first direction. The motive power apparatus is configured to drive the travelling apparatus. The detection apparatus is configured to detect an attitude of the grass-cutting robot. The control apparatus is configured to apply a control signal to the grass-cutting robot when the attitude meets a predetermined condition, the control signal causing resistance to arise in the travelling apparatus, and the resistance causing a tendency of at least part of the travelling apparatus to move in the first direction to be hindered. Further disclosed in the present invention is a control method for a grass-cutting robot. The grass-cutting robot and control method therefor according to one or more embodiments of the present invention can improve the precision of grass-cutting robot control, and increase work effectiveness and safety.

摘要： A powered fastener driver includes a first cylinder, a first piston positioned within the first cylinder, a second cylinder in fluid communication with the first cylinder, and a second piston positioned within the second cylinder. The first piston is moveable between a top-dead-center position and at or near a bottom-dead-center position and the second piston is moveable between a top-dead-center position and a bottom-dead-center position to initiate a fastener driving cycle. A drive blade is coupled to the second piston for movement therewith and a drive mechanism is configured to drive the first piston between the top-dead-center position and at or near the bottom-dead-center position. The drive mechanism includes a crank arm that rotates less than 360 degrees for moving the first piston from at or near the bottom-dead-center position and the top-dead-center position and then back to at or near the bottom-dead-center position to complete the fastener driving cycle.

摘要： A tool stand includes a table having a tool support surface and a plurality of legs movable relative to the table to define a first configuration and a second configuration of the tool stand. The plurality of legs includes a first leg and a second leg, each pivotable about a first axis, and the plurality of legs further includes a third leg and a fourth leg, each pivotable about a second axis parallel to the first axis. The tool stand further includes a base frame coupled to the third and fourth legs, and a latch mechanism including a latch element movable between a latched position and an unlatched position. The latch mechanism is configured to inhibit movement of each of the legs relative to the table when the latch element is in the latched position and the tool stand is in the first configuration.

摘要： A fastener tool which contains a motor, a drive mechanism connected to the motor and adapted to drive a piston, and a locking module. The locking module includes a rotating member coupled with the drive mechanism and adapted to rotate with a spindle and define a rotation axis; and a receiving member adapted to engage with the rotating member at and engaging portion. The rotating member includes a latch and a biasing member, wherein the biasing member moveably supports the latch in a direction substantially perpendicular to the rotation axis. Therefore, the locking module provides a locking mechanism that prevents back driving of the fastener tool that increases the lifespan and efficiency of the tool.
