Description

Dual interlocking formula V font folds handgrip

Technical field

The present invention relates to a kind of folding handgrip, particularly the folding handgrip of a kind of dual interlocking formula.

Technical background

Though folding handgrip in the market has many kinds, but the folding handgrip of dual interlocking formula V font still has no way of seeking, " the V font folds handgrip " that the design people formerly designs, though proposed relevant basic interlocking scheme, can reach firm motionless requirement behind interlocking still is some distance.

Summary of the invention

Purpose of the present invention is to provide more firm, more safe and reliable when the using dual interlocking formula V font of a kind of structure to fold handgrip.The object of the present invention is achieved like this: dual interlocking formula V font folds handgrip, comprise folding substrate, diaxon, two handgrips, two quick detach, backer's sheet, safety catch, knob, label seat and inside extending tube, it is characterized in that: folding substrate is that Al squeezing material that a shape resembles cartoon cat head profile cuts off and to process, crack and be installed with diaxon in the hole in two of folding substrate opal position, the leading portion of diaxon is welded with two handgrips, the bottom of two handgrips also is welded with safety catch, safety catch in left and right sides, knob is the combination of revolving handle and cotter pilotage, on the safety catch of a left side hole of cracking is arranged, knob is rotatably connected on the right safety catch, turning knob, the cotter pilotage of knob can pin left and right sides safety catch or unclamp, and with two quick detach locking diaxon, this folding handgrip has just formed dual interlocking formula again.

The invention has the beneficial effects as follows: will fold two of substrate and crack and penetrate diaxon in the hole, with the locking of two quick detach, form interlocking one, again with knob with left and right sides safety catch interlocking, formed dual interlocking, improved intensity and safety greatly.
