Mutually support.
As improvement, the set hole of described pullover is preferably square, and the inwall in described set hole is greater than in the bottom length of side
The inclined-plane of the top length of side.
As improvement, described vertical inserted link be located on adjacent one side also can be provided with after pullover ratates 90 degrees can with vertical
Inserted link locks and the card division with front same structure shirked and vertical chute.
The inclined-plane being adapted with set in the hole wall inclined-plane as improvement, the side of described latch.
As improvement, the middle part outer peripheral face of described latch is concavely provided with annular cavity, and the inner end outer peripheral face of latch forms ring
Shape collar, is being respectively arranged with vertical perforation, between the pin hole below annular cavity and pullover bottom surface in perforation
From bottom to top being plugged with upper end respectively and stretching into prevents in annular cavity latch from being released the stop pin of pin hole by support spring.
As improvement, the card division widthwise edge of described vertical inserted link is the high hypotenuse in the low inner side in outside.
Compared with prior art, the present invention is using the pin hole being horizontally arranged with two insertion of pullover, in pin hole
Two can actively be plugged with latch respectively, and the outer end of described latch each extends over out outside pin hole, and the inner end of described latch is divided
It is not provided with annular collar, the upper side of described vertical inserted link is horizontally arranged with the card division with annular collar phase buckle,
The vertical chute that width is at least two annular collar width is vertically provided with the vertical inserted link of card division medium position.This
The advantage of structure is：Handlebar can easily be fixed with headstock phase by pullover, just can shirk without instrument and fix, and
And fixation, it is difficult to loosen, when handle needs to extract from headstock, as long as pressing pullover both sides latch with hand, handle is just
Can extract from headstock, and when clamped, as long as hand is pressed the latch in pullover both sides, the pullover set in handle be inserted in again
On the vertical inserted link of headstock, then hand is decontroled, pullover is just locked together with headstock automatically.So it is easy to operate；And
Handlebar can turn to fixation with same method.Therefore, the present invention is a kind of very useful and secure attachment device.
