A vacuum sucker is installed on a robotic arm to suck an object. The robotic arm includes a body and a tip axis. The tip axis is disposed with an adapter plate. The vacuum sucker includes a housing, an actuator, and a flexible suction cup. The actuator passes through the housing and includes a main part, a thrust rod, and an elastic element. The main part has a first end and a hollow slot. The flexible suction cup is sleeved on the first end and is formed with an air chamber. When the thrust rod is located at the first position, the air chamber and the hollow slot are not intercommunicated with each other. When the thrust rod is driven by the adapter plate to move to a second position, the air chamber and the hollow slot are intercommunicated with each other.

A quick-release fastener structure includes a body portion and an engaging portion. The body portion is fitted to a first object. The engaging portion is movably fitted to the body portion. The engaging portion has a head portion, a bar portion with an end connected to the head portion, and an engaging-connecting portion disposed at another end of the bar portion. The engaging-connecting portion is insertedly engaged with or separated from a second object. Therefore, the quick-release fastener structure operates by fitting the body portion to the first object and allowing the engaging portion to be engagedly connected to the second object or removed from the second object, such that the at least two objects are coupled together and separated repeatedly and quickly.

A fastener for securing a first object to a second object includes a push member, a rigid shaft, an engaging member, a biasing member, and an anchor. The push member and the anchor are fixed to opposite ends of the rigid shaft. The engaging member is slideably coupled to the rigid shaft between the push member and the anchor. The biasing member is disposed between the push member and the engaging member to urge the engaging member toward the anchor. In a particular embodiment, the anchor is deployable.

A counter mount fluid dispenser has a spout having an opening for dispensing a fluid. The connection shaft extends downwardly from the spout. A swivel base is mounted to the connection shaft. The swivel base swivels relative to the connection shaft. The swivel base includes a mounting shaft having a mounting shaft nut that is configured with the spout to engage a countertop by clamping force. The mounting shaft nut has a mounting shaft nut lower extension. A mounting shaft nut external thread is formed on an external surface of the mounting shaft nut lower extension. A mounting shaft nut retainer is threaded to the mounting shaft nut lower extension.

A tie-down anchor for use with decking boards, or the like, having a gap with a longitudinal axis located between adjacent decking boards. The tie-down anchor includes a continuously formed anchor having a lower leg extending in a first direction in a first horizontal plane, a vertical section connected to the lower leg and perpendicular to the first horizontal plane, an upper leg that is parallel to the lower leg and lies in a second horizontal plane spaced above the first horizontal plane by the length of vertical section, and a loop above the vertical section and the upper leg. Wherein the lower leg can be inserted within the gap between adjacent decking boards and the loop turned to trap the anchor between the decking boards such that the upper leg and lower leg are perpendicular to the longitudinal axis of the gap.
