1. Core material characteristics
The main material is 304 stainless steel, which is highly resilient, resistant to bending, and less prone to cracking; it comes with a natural passivation anti-rust layer and is non-magnetic, allowing for selection without interfering with the magnetic signals of precision electronic equipment; the spring is also made of stainless steel, and will not rust or fail in a long-term humid environment, unlike carbon steel springs which tend to rust and jam.
2. Detailed category process structure characteristics
Spring telescopic plug
Stainless steel fixed plate + integrated compression spring + smooth round rod. Pressing it will retract, and it will automatically pop out and lock when released; the fixed plate has double installation holes, which can be directly fixed on the box or equipment door, and the rod diameter has multiple specifications, suitable for locking different thickness door panels.
Spring self-locking clip
Double-layer bent steel plate combined with stainless steel elastic clip. It automatically clamps the workpiece by relying on the spring tension, and both sides have arc-shaped card slots for positioning, one click locks, and disassembly only requires a gentle twist of the clip. It is mostly used for quick fixation of covers and plates.
Universal ball head adjustable hoisting rope component
It is divided into a hoisting ring screw type and a double-ear hinged screw type. The middle has a universal moving ball head that can adapt to the installation angle; the screw has precise rolling teeth throughout its length, and is used with U-shaped hoisting clamps and double-ear hangers, allowing for free adjustment of the tension distance, suitable for flexible hoisting and tensioning of curtain walls, sunshades, and equipment.
U-shaped adjustable clamping bracket
U-shaped integrated bent slot body, combined with bolts and nuts for locking, the space inside the slot can hold pipes, steel plates, and roof trusses, and tightening the bolts can fix it, disassembly is convenient, suitable for temporary or permanent clamping and positioning of profiles.
Hinge connecting rod hanger accessory
Long strip stamped steel plate riveted with a rotating shaft, both ends have installation holes, combined with the hoisting rope and clip for use, extending the installation distance, suitable for long-distance cross-component connection assembly.
3. General physical process characteristics
The thickness of the sheet is 0.8mm - 3.0mm, and the diameter of the plug is 3mm - 12mm, with multiple specifications layered. It can be matched for light-load small equipment and heavy-load engineering hoisting. 
Metric standard threads, compatible with common screws and nuts on the market, with strong interchangeability.
The surface has a native brushed treatment, which is not prone to water accumulation and dust, and slows down the corrosion rate.
All moving parts have precise gaps, and pushing, rotating are smooth without jamming.

304 stainless steel raw material, long-term rust prevention in all scenarios
The entire product is made of national standard 304 stainless steel, without galvanizing or painting coatings, eliminating the risk of coating peeling and rusting; resistant to rain, salt spray, weak acids and weak alkalis, suitable for long-term use in coastal areas, open-air, damp workshops, and mild corrosive environments in chemical industries without oxidation and rusting; adaptable for outdoor long-term working conditions.
Multifunctional composite structure, meeting multiple assembly requirements with one set
The spring plug latch achieves automatic extension and locking of the door through the spring, and is easy to disassemble and assemble; the spring clip relies on the elasticity to quickly clamp, without the need for additional locking tools; the universal lifting rope is combined with a ball head for multi-angle free deflection, and the screw rod has full teeth for adjustable tension length; the U-shaped clamp can hold the profile for secure locking and can cover all requirements of locking, lifting, clamping, and adjustment, reducing the need for multiple types of purchases.
Integrated molding + precise assembly, sturdy and durable structure
The main body of the plug and clip is formed by one-time stamping and bending of stainless steel plates, without splicing or welding; the ball head of the universal lifting rope and the screw rod are formed by turning, and are fully inspected by thread stop gauge; the built-in stainless steel spring ensures stable elasticity and does not fatigue and break after tens of thousands of reciprocating uses, with stable load-bearing and vibration resistance performance.
Universal adjustable design, high installation tolerance rate
The lifting rope component is equipped with a universal ball head structure, which can make a small 360° deflection to adapt to irregular installation surfaces; the full-threaded screw rod can freely adjust the tensioning travel, and the long round hole and multi-sized installation holes can adapt to the dimensional deviations of the site, significantly reducing the difficulty of construction and assembly.
Smooth and precise processing without burrs, no damage to the workpiece during assembly
All cutting edges of the plates, the ends of the plug rods, and the edges of the threads are treated with passivation and deburring, the surface is matte and brushed, and will not scratch aluminum profiles, color steel plates, or equipment paint surfaces; the edge of the spring is smooth without sharp edges, and is not likely to scratch the operator during use.
Flexible customization, suitable for non-standard special working conditions
The plug rod diameter, spring elasticity, clamping opening width, screw rod length, and lifting ring load specifications can be adjusted as needed, and customized for various special structures such as elongated suspensions, widened U-shaped slots, and extended adjusting threads, and small batch prototyping and large-scale engineering supply can be undertaken.
