Description

Dual interlocking formula vee shape folds handgrip

Technical field

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

Technical background

Though folding handgrip in the market has many kinds; But the folding handgrip of dual interlocking formula vee shape still has no way of seeking; The design people is design-calculated " vee shape folds handgrip " formerly; Though proposed relevant basic interlocking scheme, behind interlocking, can reach firm motionless requirement still is some distance.

Summary of the invention

The object of the invention is to provide more firm, more safe and reliable when the using dual interlocking formula vee shape of a kind of structure to fold handgrip.The objective of the invention is to realize like this: dual interlocking formula vee shape 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,, form interlocking one with the locking of two quick detach, again with knob with left and right sides safety catch interlocking, formed dual interlocking, improved intensity and safety greatly.
