The specific embodiment:
According to Fig. 1; Described cup joint style lock-connecting piece vee shape folds handgrip, comprise handgrip pedestal 1, backer's sheet 11, left side axle 21, right axle 22, a left side connect part 31, right connect part 32, left hand 41, right handgrip 42, left interlocking connect part 51, right interlocking connects part 52, pressure box 6, quick detach 7, safety catch 8 and inside extending tube 9.
Described handgrip pedestal 1; Be aluminium section bar, the two opal positions of a cat head profile have two upwards the band hole of cracking, cut-out after form after the perforate processing; Said handgrip pedestal 1 crack perpendicular place, hole have two pairs to the perforation; It is one downward to perforation that the centre at said handgrip pedestal 1 top has, and upwards there is a counterbore centre of said handgrip pedestal 1 bottom, the said counterbore close-fitting socket one described inside extending tube 9 of said handgrip pedestal 1.
Described backer's sheet 11; It is the aluminum component of being with convex globoidal down; Have a hole on described backer's sheet 11, a hanging bolt penetrated in the hole of said backer's sheet 11, penetrate again said handgrip pedestal 1 top to the perforation in; Be screwed in the tapped bore that pierces into the bloated plug in the bicycle front fork pipe again and tighten, described backer's sheet 11 and the described pedestal 1 and the front fork tube of bicycle are fixed.
Described left side axle 21 is that columniform Al squeezing material cuts off workpiece with described right axle 22; The fixedly sleeved respectively circular hole and the said right side in a said left side even part 31 bottoms in said left 21 front portion and the front portion of said right axle 22 connects in the circular hole of part 32 bottoms; The center of the center of axle 21 rear ends, a said left side and said right axle 22 rear ends has screw; Crack in the hole in the left side that the rear portion of said left side axle 21 is penetrated said handgrip pedestal 1; Crack in the hole in the right side that the rear portion of said right axle 22 is penetrated said handgrip pedestal 1; Cover two pads, with the two anti-bolts that fall twist in the screw that is connected on axle 21 rear ends, a said left side and the screw of said right axle 22 rear ends in locate, again with two pairs to the lock bolt penetrate with said handgrip pedestal 1 crack perpendicular place two couples in boring a hole, tighten to the degree of tightness appropriate level.
A described left side connects the workpiece that part 31 is aluminium extruded type sections of a b shape; One circular hole is arranged at the bottom that a said left side connects part 31; The cylinder that the top that a said left side connects part 31 has a Vehicle Processing to form; A said left side connect the cylinder of part 31 fixedly sleeved in said left hand 41 bottom, the described right workpiece that part 32 is aluminium extruded type sections of a d shape that connects, a circular hole is arranged at the said right even bottom of part 32; The cylinder that the said right top that connects part 32 has a Vehicle Processing to form, the cylinder of said right even part 32 is fixedly sleeved in the bottom of said right handgrip 42.
