The main attention when designing: 1) to the side of the core's withdrawal, the top of the latch should lower oblique 0.05 0.1 mm core plate surface ÷, in the process squeezing, pegs the skewers make withdraw the core, moving in. To prevent collision radius from the bottom of the plastic on the core product, the underside is higher than that of the structure, in the meantime, symmetrical face move S of RADIUS bo structure must be provided with S1 which is wider than s. so, stumbling as the banks can avoid collisions on the core. S1 > s. 2) tilt angle of β-locking should take in about 5 ÷ 25°, and angle α guidance on the core structure of the withdrawal should be less than or equal to β, α ≤ β. Preventing Collisions between the oblique and core of the bevelled part latches protrude. 3) structure with function, the length of the rounded leading edge better wider than may, the 4 corners of the slider should do rounded corners to facilitate the process of milling. The design ensures stable and sure of the mechanism and expand the distance of the process. 4) When sliding friction appears between the latch plate and oblique plate's pushing, need hard surfaces to enhance my computer against abrasion.
