Description of the drawings
Fig. 1 is a kind of structure diagram of compact-sized non-return type connector proposed by the present invention.
Specific embodiment
In the following, technical scheme of the present invention is described in detail by specific embodiment.
As shown in FIG. 1, FIG. 1 is a kind of structure diagrams of compact-sized non-return type connector proposed by the present invention.
Reference Fig. 1, a kind of compact-sized non-return type connector that the embodiment of the present invention proposes, including：Screw rod 1 and fixation
Limited block 2 in 1 one end of screw rod, wherein：Screw rod 1 is internally provided with the center cavity extended along its length, and the side wall of screw rod 1 is set
There are the first duct be connected with the center cavity, the second duct, the first duct, the second duct are axial arranged slotted hole, and
First duct, the second duct are located along the same line；It is set on center bore inner wall and positioned at side of first duct far from limited block 2
There is the first fixed seat 3, being equipped with second positioned opposite with the first fixed seat 3 positioned at side of second duct far from limited block 2 consolidates
Reservation 4.
Centre bore is internally provided with push rod 5, the first fore-set 6 and the second fore-set 7；Push rod 5 is axial arranged in centre bore, and
Push rod 5 is equipped with close to one end of limited block 2 and extends to external briquetting 8 against and through limited block 2 with it, and push rod 5 is separate
One end of limited block 2 be equipped with it is axial arranged and with its against compressed spring 9；The middle part difference of first fore-set 6, the second fore-set 7
It is flexibly connected with the first fixed seat 3, the second fixed seat 4, the first fore-set 6, one end of the second fore-set 7 are movable even with push rod 5 respectively
Connect, and when compressed spring 9 in the raw when, the first fore-set 6, second one end of fore-set 7 far from push rod 5 are each passed through first
Through-hole, the second through-hole extend to the outside of screw rod 1.
The present invention works in this way：First duct, the second duct are set by the side wall in screw rod 1, inside screw rod 1
