What the claims cover, in plain language

Claim 1 defines a clamping tool comprising an anchor backing plate body positioned horizontally. A first extrusion unit engages the narrow-mouth end, and a second extrusion unit engages the wide-mouth end.

The second extrusion unit includes a moving platform capable of transverse movement. Attached to this platform are first inclined arms that rotate to drive outer support plates. These plates are right-angled: one surface touches the exterior of the anchor pad, and the perpendicular surface inserts into the interior.

Mechanically, second inclined arms connect the support plates to sliding blocks within grooves on the platform. Leaf springs exert force to keep the arms pressed against limit plates and stopper blocks, thereby fixing the position of the sliding blocks and locking the grip. The platform rides on rolling wheels over anti-skid plates with conical ends, supported by a base table with vertical columns and top plates secured by further springs.

This is a simplified reading for orientation only. The legal scope is defined by the exact claim wording in the official Chinese document.

What this means for US production

This patent was filed only in China and is currently in force. Making or selling this specific design in China requires the owner’s permission. There is no US patent corresponding to this application.

Two points to settle early:

  • Other patents may exist. Construction inspection fixtures and clamping mechanisms are a broad field. While no foreign patents citing this one were found, general freedom-to-operate (FTO) reviews should consider existing US patents on variable-jaw chucks and spring-loaded clamps.
  • Material compatibility. The fixture interacts directly with steel or cast iron anchor pads. Surface hardness of the clamping plates must be selected to avoid scratching the workpiece if it is reused or if cosmetic finish matters.

Customization and manufacturing

What can be customized

AreaOptions
Clamp RangeAdjust stroke length of the moving platform to fit different anchor pad widths.
Plate MaterialTool steel, stainless steel, or polymer-coated faces for softer grips.
Spring ForceSelect leaf spring thicknesses to match the weight and friction of the anchor pad.
Mounting InterfaceAdd bolt patterns for integration into CNC tables or manual benches.
Wheel TypeReplace rolling wheels with low-friction bushings if movement speed is less critical.

Things to plan for (US market)

  • OSHA General Duty Clause: Ensure pinch points between the moving platform and support plates are guarded or designed to prevent injury during operation.
  • ISO 9001 / ASME Y14.5: If supplying to engineering firms, tolerance stack-ups on the inclined arms must be documented per GD&T standards.
  • Material Traceability: For construction-related tools, some buyers require mill certificates for the steel components.

How a project runs

  1. Inquiry - Specify anchor pad dimensions and required clamping force.
  2. Design - Calculate arm leverage ratios and spring constants for the specific geometry.
  3. Prototype - Machine the platform and arms; assemble to test repeatability of the lock.
  4. Pilot run - Verify durability of leaf springs and wear resistance of support plates.
  5. Production - Machining of structural parts, stamping of springs, assembly, and calibration.

Quantities & timeline

The moving platform and base require precision milling. The inclined arms and support plates are machined parts. Leaf springs can be stamped or laser-cut. Assembly involves setting the preload of the springs to ensure the locks engage correctly. Send us your anchor pad dimensions, quantity needs, and integration requirements and we will reply with options.
