HiSmith Premium Sex Machine Original – Powerful Sex Machine

The Hismith AK-01 third-generation sex machine delivers adjustable stroke depth from 1.18 to 5.9 inches and full 0-90° angle positioning in a self-stabilizing steel frame designed for users who need reliable performance and multi-position versatility. This is a mechanically-driven reciprocating piston machine with enough inherent weight to remain stable during use without additional anchoring.

Key Specifications

• Stroke Range: 1.18–5.9 inches (3–15cm), infinitely adjustable via exposed adjustment arm
• Angle Adjustment: 0–90° continuous range — supports horizontal, angled, vertical, and inverted positioning
• Frame Dimensions: 468mm W × 245mm D × 120mm H (main body); 449mm piston rod extension; 89mm rod diameter
• Support Legs: 260mm height, quick-release clamps, chrome-plated tubes with rubber feet
• Drive Type: Reciprocating piston with 244mm visible stroke arm
• Frame Construction: Steel chassis with matte black finish; integrated aluminum alloy cover plate (third-generation upgrade)
• Attachment Connection: Standard Vac-U-Lock compatible fitting on chrome piston rod
• Power Source: Mains AC (plug type varies by region)
• Assembly: Tool-free leg repositioning via quick-release clamps

Third-Generation Cover Plate Upgrade

This AK-01 features the redesigned aluminum alloy cover plate that encloses the piston mechanism while leaving the adjustment arm accessible. Earlier versions used an open-frame design; this integrated cover protects internal components from lubricant contamination and environmental debris, extending service life. The cover is secured but removable for maintenance.

Infinite Position Adjustment

The frame's quick-release leg system allows complete repositioning without tools. Loosen the clamps at the leg joints, rotate the main body to your desired angle, and re-tighten. The machine transitions from horizontal bench mounting to vertical floor positioning, angled configurations, or inverted setups in under a minute. The four support legs provide a stable base regardless of orientation, and the rubber feet prevent sliding on smooth surfaces.

The stroke length adjustment arm is exposed on the left side of the drive housing. Reposition the attachment point along the arm's track to increase or decrease stroke depth — moving closer to the pivot reduces stroke length for shallow motion; extending toward the end increases it to the full 5.9-inch range. This adjustment is made manually while the machine is powered off.

Frame Stability and Build Quality

The steel frame's solid construction provides enough mass to self-stabilize during operation. Most machines in this class require suction cup anchoring or edge clamping; the AK-01's weight distribution keeps it in place on flat surfaces without additional securing. The chrome-plated support legs are height-adjustable and lock via the same quick-release clamps used for angle changes.

Attachment Compatibility

The chrome piston rod terminates in a standard Vac-U-Lock fitting, making this machine compatible with hundreds of dildos, masturbator sleeves, and specialty attachments from Vac-U-Lock, Doc Johnson, and other manufacturers using this connection standard. Attachments lock onto the rod with a twist-and-secure motion; no tools required. If you already own Vac-U-Lock compatible toys, they will fit directly.

Control and Operation

Speed is controlled via a wired remote (confirm inclusion with supplier). The machine operates on mains AC power, eliminating battery recharge cycles and providing consistent thrust force throughout sessions. The reciprocating drive mechanism converts rotary motor output into linear piston motion — this is a mechanical system, not a cam-driven one, which typically results in more consistent stroke delivery.

Included and Compatible

Confirm with your supplier whether any Vac-U-Lock attachments, the speed control remote, or additional accessories are included with the frame. The machine is shipped partially disassembled; leg installation requires only inserting the chrome tubes into the body clamps and tightening — no hex keys or fasteners needed.

Dimensions Summary: 468mm × 245mm × 120mm body; 260mm leg height; 449mm rod length; total footprint approximately 468mm × 520mm when legs are fully extended in standard horizontal orientation.
