Two 1 groups of both sides for being symmetrically distributed in telescoping handle 10, rebound part 14 is not connect with fixed plate 13, when telescoping handle 10 is contracted to
When the inside of side case 4, fixed plate 13 squeezes rebound part 14, and making telescoping handle 10 always has to far from middle 3 side of moving of position case
To trend, by moulded rod 5, card cylinder 7 moves downward, and when card hole 8 is detached with fixture block 15, telescoping handle 10 is in rebound part 14
It is launched away to the direction far from middle position case 3 under effect, that is, extends the horizontal length of valve body control piece 2, rebound part 14 is separate
The side of fixed plate 13 is welded in side inner wall of the side case 4 close to middle position case 3.
The part 14 that rebounds includes baffle 16, boom 17 and sleeve 18, and side of the baffle 16 far from fixed plate 13 is leaned on boom 17
One end of nearly fixed plate 13 is fixedly connected, and the one end of boom 17 far from baffle 16 runs through the side wall of sleeve 18 and extends to sleeve 18
Inside be fixedly connected with the side of limiting plate 19, the other side of fixed plate 19 is installed with contained spring 20, contained spring
20 one end far from limiting plate 19 is fixedly connected with side inner wall of the sleeve 18 far from boom 17, and the outer surface of boom 17 is arranged with
One end of external springs 21, external springs 21 is fixedly connected with baffle 16 close to the side of boom 17, and 20 He of contained spring is arranged
External springs 21 make the elastic property of rebound part 14 more preferably, and the other end and the sleeve 18 of external springs 21 lean on the side through baffle 16
It is fixedly connected.
Operation principle：When needing rotating valve, plate 6 is pressed in pressing, and card cylinder 7 moves downward, when card hole 8 is detached with fixture block 15
When, telescoping handle 10 launches away under the action of rebounding part 14 to the direction far from middle position case 3, the level of valve body control piece 2
Extension, when rotating valve, are more laborsaving.When packing up telescoping handle 10, telescoping handle 10 need to be only depressed into side case 4
Portion, fixture block 15 contact with card hole 8 and are pressed down against card cylinder 7, when the recess that fixture block 15 moves to 15 bottom of fixture block is contacted with card hole 8
Engaging, you can fix telescoping handle 10 and card cylinder 7, the volume of valve body control piece 2 can be controlled in smaller range, does not influence
The operation of other component.
In conclusion the labour-saving valve, flexible inside side case 4 by telescoping handle 10, make the length of valve handle
Degree is adjustable, and the keying torque of valve is controlled, and keeps the keying of valve more laborsaving, while being provided with positive stop strip 11, adds
The strong intensity of telescoping handle 10, keeps telescoping handle 10 not easy to break in rotation, improves the stability of valve, pass through simultaneously
The cooperation of fixture block 15 and card cylinder 7, telescoping handle 10 can be fixed when shrinking, it is therefore prevented that telescoping handle 10 prolongs in smaller space
It stretches and the operation of other component is impacted, improve the practicability of laborsaving valve.
Also, by the cooperation of card cylinder 7 and screens spring 9, it need to only press and press plate 6, card hole 8 is detached with fixture block 15, simultaneously
Telescoping handle 10 moves under the action of rebounding part 14 to the direction far from middle position case 3, makes 10 auto-extending side case 4 of telescoping handle
Outside, the control enhanced convenience of the horizontal length of valve body control piece 2 is easy to operate, convenient for control, while rebound part 14
Inside be provided with contained spring 20 and external springs 21, make the elastic property of rebound part 14 more preferably.
