The quick release interconnect includes a mount member that includes a cleat and a top hanger seat. An attachment member includes a lower jaw that is spring-biased into an open condition that can be secured closed by a cam-lock lever. An upper jaw hanger is also provided to permit the attachment member to be hung on the top hanger seat while the attachment member and object are oriented in place. The upper jaw hanger member is located over the top hanger seat and then the attachment member is rotated in place so the lower jaw is aligned with the cleat. The cam lock lever is rotated to clamp the lower jaw into communication with the cleat portion of the mount member to secure the attachment member securely to the mount member. To release the attachment member, the process is reversed.

A pin-type connection apparatus includes a first connecting seat, a second connecting seat, a connecting shaft, and a locking component, wherein a receiving hole and a locking hole on the adjacent side of the receiving hole are disposed on the second connecting seat, one end of the connecting shaft is fastened to the first connecting seat, a clamping hole is disposed at the other end of the connecting shaft, the connecting shaft can extend into the receiving hole, a first clamping protrusion is disposed in the clamping hole, a second clamping protrusion is disposed at one end of the locking component, and the locking component can pass through the locking hole and extend into the clamping hole; and when the locking component is rotated to a lockout position, the first clamping protrusion can abut against the second clamping protrusion and restrain the second clamping protrusion from exiting the clamping hole.

A fastener system for securing a panel to a frame comprises one or more rotating fasteners installed in the perimeter edge of the panel. In operation, one or more cam surfaces of the fastener engage receiving surfaces of a receiver on the frame such that, upon rotation of each fastener, the panel is drawn toward the frame. In some embodiments, the panel is moved in a first direction parallel to the panel and a second direction perpendicular to the panel or in a composite diagonal direction inclined relative to the panel. The fastener system may facilitate compression of seals disposed along the perimeter edge of the panel and between a side of the panel and rabbet ledge of the frame and may further facilitate removal and maintenance of the panel.

A spring clamp wherein a reduced effort is needed on the handle end as the engagement end is opened further. The spring clamp can include a clamping force adjustment means through the use of a spring pack, central rod and a folding adjuster. The spring clamp can also include low friction mounts at the ends of a spring pack to reduce user effort on the handle end.

The present invention is an improved fluid valve control device which attaches to a pre-existing and pre-installed hex head valve. The valve control device has at least one lever which can be used to turn the valve on or off. This device can be attached to a manifold assembly that has a valve which typically requires a tool to control so that it eliminates the need for a separate tool being used to turn the valve on or off after installation at relatively low cost.

An embroidery machine includes an outer ring, an inner ring, a pair of screw mounts, a lever, a nut, and an adjusting screw. The outer ring includes a dividing portion. The inner ring and the outer ring holds a workpiece therebetween. The screw mounts are disposed at the dividing portion to oppose each other. The lever is disposed at one of the screw mounts and rotatable about a rotation axis. The nut is slidably held in the lever at a position eccentric from the rotation axis. The adjusting screw is mounted across the screw mounts and threadedly engaged with the nut. A shortest distance between a first surface of the one of the screw mounts and the nut is defined as a specific distance. The specific distance when the lever is at a second position is longer than the specific distance when the lever is at a first position.

A tuning apparatus for a stringed musical instrument is provided. The apparatus includes a dual-action cam clamp assembly and a plurality of string-contacting members with easy-to-adjust rocker arms. The dual-action cam clamp assembly removably attaches to a desired longitudinal position on the instrument's neck. Each of the string-contacting members is rotatably supported by a rocker arm shaft, and the easy-to-adjust rocker arms are adapted to rotate about the longitudinal axis of a two-part shaft of the clamp assembly independently of the other string-contacting members. Each member also adjustably impinges upon and urges a given string or course thereof on the instrument toward a user-selectable one of three different longitudinal positions on the neck's front surface, these positions including a home position, a home−1 position, and a home+1 position.
