Specifically, the projection length of the buckle is 40×46×26mm, and the length of the clamping groove part is 5mm.

Specifically, in the use, buckle 1 is through upper and lower draw-in groove portion 4, and chucking ground flat iron 7 is not hard up, consequently needs to have enough mechanical strength to support ground flat iron 7, guarantees at same horizontal plane, simple to operate. Therefore, the requirement on the processing technology of the buckle is higher, and certain requirements on the elasticity and strength of the material are also met. During initial manufacturing, a steel belt with the thickness of 1-3mm is manually adopted to be processed on site according to a design drawing, and a semi-manually processed finished product is low in quality, process and strength, and cannot meet the effect of design requirements after testing. The non-manual processing can be completed, and after market investigation, mechanical die sinking and stamping are finally adopted for one-step forming. The galvanized steel sheet with the thickness of 3mm is selected as the material, and the qualified product with the design requirement is finally finished through repeated testing, die adjustment and retesting by the process procedures of cutting, perforating and twice stamping.
