A lift buffering structure includes a hollow column-shaped housing, a holding seat fixedly connected to an inner wall surface of the hollow column-shaped housing, an inner stem disposed in the hollow column-shaped housing and slidably extended through the holding seat, an elastic element having an end connected to the inner stem and another end to the holding seat to limit a travel stroke of the inner stem, an abutting unit disposed at one side of the holding seat opposite to the elastic element and having a width downward reduced gradually along a height direction of the hollow column-shaped housing, and an anti-slip unit connected to a lower end of the inner stem and located between the abutting unit and the inner wall surface of the hollow column-shaped housing. The lift buffering structure having the above structure can overcome a lot of problems in the conventional gas and oil struts.

A telescoping support stand comprising handle mounted below a connection housing and a plurality of extendable legs pivotably engaged near the top of the connection housing.

An electrical connector for removably engaging a welder to a spot welding tool having a first arm in a pivoting engagement to a second arm. The connector features an electrically conductive member engaged to or forming a powered translating shaft of a welder which is surrounded by a housing. The connector engages within a passage formed in a coupling to communicate forward and rearward movement and electric current to a first arm of a spot welding tool.

A lift adjuster is depicted and described for adjusting seating furniture and/or reclining furniture, with a housing and an adjustment bracket. The adjustment bracket is maintained in the housing and can be partially pulled out of the housing. In order to enable comfortable adjustment, it is proposed that at least one clamping element is provided displaceable with respect to the adjustment bracket between a clamping position and at least one adjustment position in that the at least one clamping element is received in a clamping manner in the clamping position in a clamping gap between the adjustment bracket and the housing such that the adjustment bracket is prevented from sliding into the housing.

A device for locking a rod member is provided. The device includes a body section having a vertical hole therein, and a ring-type locking unit and a piston serially arranged along the hole, wherein the rod member is disposed in the hole to be axially movable through the locking unit and the piston. The locking unit may be a lock block including an outer ring having an inclined surface on one side thereof, thereby defining a wedge-type space, an inner ring coaxially disposed in one side of the outer ring and accommodating a pressurizing member interacting with the inclined surface, and a spring disposed in the other side of the outer ring so as to elastically connect the outer ring and the inner ring.

The present disclosure may include a leg comprising first and second tubes, the first tube inside of the second tube, a lock mechanism within the second tube, the lock mechanism including a plug, a ramp, and bearings configured to roll along the ramp and contact the ramp and at least an interior wall of the first tube such that as the one or more bearings contact the ramp and the interior wall of the first tube, motion of the second tube relative to the first tube is inhibited, and a third tube inside of the second tube, and in response to the third tube being substantially disposed within the second tube, a proximate end of the third tube configured to push the one or more bearings towards the plug, reducing the interference of the one or more bearings with the interior wall of the first tube.

An accessory or gun-mounted support stand apparatus including a release mechanism and locking mechanism configured to allow or prevent longitudinal movement of telescoping legs.
