A seat track slide device includes a pair of seat tracks. Each seat track has a lower rail, an upper rail, a lock lever, and a handle and is capable of switching the associated upper rail to locking and unlocking states by selectively engaging and disengaging the lever with respect to the lower rail. Each lever is inserted into the corresponding upper rail and pivotally supported in the upper rail. An interlock support portion of the lever projects into an outer zone with respect to the front end of the upper rail. The interlock support portion of the lock lever supports an interlock support portion of the handle pivotally relative to each other. With the lever maintained in the locking state, the handle is allowed to pivot relative to the lever in the outer zone with respect to the front end of the upper rail against elastic force produced by a torsion coil spring arranged in the upper rail.

The invention discloses a C-type wingceltis bar and cross beam end adjustable connecting part. The C-type wingceltis bar and cross beam end adjustable connecting part comprises positioning columns andlimiting plates, the four positioning columns are vertically mounted, a C-type wingceltis bar and the end of a cross beam are sequentially stacked up and down, and are interspersed in among the fourpositioning columns in a cross manner, the limiting plates are horizontally mounted, the two ends of the limiting plates are provided with adjusting openings in the length direction, locking blocks sliding in the length direction of the limiting plates are mounted in the adjusting openings, the four limiting plates are mounted on the top ends and the bottom ends of the positioning columns, the four limiting plates are arranged in sequence end to end in a rectangular manner, the adjusting openings in the two ends of the limiting plates are arranged in the ends of the two adjacent positioning columns in a sleeving manner, the locking blocks tightly abut against the positioning columns, and locking assemblies are mounted on the locking blocks. The adjustable connecting part has the advantagesof being suitable for C-type wingceltis bars and cross beams of multiple specification sizes and the large in locking range.

A clamping device includes a body, a clamp arm and a drive mechanism that includes a displacement body displaced linearly, wherein the clamp arm is rotated based on the displacement of the displacement body. The displacement body includes a guide surface for guiding the rotation of the clamp arm, and also for controlling the rotation of the clamp arm while the clamp arm is in a clamping state. The clamping device further includes a push mechanism disposed at a position facing a lever arm and elastically pushing the displacement body toward the lever arm.

An optical frequency locking method tunes each of a plurality of narrow-band optical channel transmit signals (having arbitrary channel frequency spacings) to a dedicated optical channel frequency. The method includes tapping-off a portion of the optical power of the respective channel transmit signal and filtering the tapped-off channel transmit signal using at least one optical filter device. The method also includes monitoring, as an optical input signal, the optical power of the respective channel transmit signal supplied to the at least one optical filter device and, as an optical output signal, the optical power of the filtered channel transmit signal. The method further includes tuning, within a predetermined locking range for the dedicated optical channel frequency, the optical frequency of the respective channel transmit signal such that a predetermined value for the ratio of the output signal and the input signal is reached.
