This spring attachment introduces variable movement dynamics to HiSmith KlicLok system setups by functioning as a flexible intermediary component between the machine and attachment. The coiled spring design absorbs and redistributes the machine's thrust force, converting rigid linear motion into responsive movement that adjusts to resistance and repositioning during use. Specifications Length: 4.13 inches (105mm) total extension Compatibility: KlicLok system only (HiSmith Premium Sex Machines with KlicLok connections) Construction: Spring-wrapped core with reinforced hex nut coupling points Connector Type: KlicLok quick-connect on both ends (male and female) Finish: Matte black throughout Material: Industrial-grade steel spring with ABS housing components Mechanical Function The attachment features a tightly wound spring core running the full length between two knurled coupling nuts. Each end terminates in a KlicLok connector—one male, one female—allowing it to link directly between the machine's rod and any KlicLok-compatible attachment. The spring absorbs forward thrust force and returns energy during the retraction phase, creating a bounce effect that differs from direct rigid coupling. This design permits the attached toy to move independently within the spring's compression range while maintaining the machine's stroke pattern. The hex nut sections on each end provide grip surface for hand-tightening connections without tools. The knurled cap at the machine-side connection allows for secure attachment to the machine's drive rod. Compatibility Requirements This component requires a HiSmith Premium Sex Machine equipped with the KlicLok connection system and KlicLok-compatible attachments. It will not fit Vac-U-Lock, standard HiSmith threading, or other attachment systems. Both connection points must use the KlicLok quick-connect standard for proper assembly. The spring adds 4.13 inches to the overall distance between the machine's mounting point and the attachment, which affects positioning and may require adjustment of the machine's placement relative to the user.
