Motor is connected with screw rod transmission, and feed screw nut is provided with the telescoping inner, and one end and the feed screw nut's screw thread of the screw mandrel connect
Connect, one end of telescoping inner is provided with screw mandrel locating ring, and screw mandrel locating ring is threadedly coupled with the other end of screw mandrel, the outer telescopic tube
One end be fixedly connected by blanking cover with one end of telescoping inner, and the other end of outer telescopic tube is provided with positioning sleeve, and shell
Periphery is provided with axially position raised line, and the positioning sleeve connects with the sliding of axially position raised line.
Inlet wire pipe is fixedly connected with the end cap, the end cap is provided with entrance hole, and is threaded with end cap
One joint.
One end end of the telescoping inner is provided with nipple, and the second joint is threaded with nipple.
The screw mandrel is provided with noise reduction ring at feed screw nut.
After said structure, the utility model on the basis of an original telescoping tube due to being changed to telescoping inner and stretching
Contracting outer tube two, telescoping inner are mainly responsible for the transmission with screw mandrel, and outer telescopic tube primarily serves carries out guide effect using shell.
Therefore relative to prior art, the guide effect of telescoping inner and outer telescopic tube in telescopic process is improved, is ensured in flexible
Pipe and the axiality of outer telescopic tube and screw mandrel, improve service life.
