[specific embodiment]
Refering to fig. 1 and Fig. 2, a kind of easily take off of the present invention take expansion tube, including end plate 1 and tube body 2, and the tube body 2 includes
The right end of first rank pipe 21 and second-order pipe 22, the first rank pipe 21 is connected with end plate 1, and the end plate 1 is equipped with first
First grooving 12 of the first threaded hole 11 of threaded hole 11 and perforation, the first rank pipe 21 are equipped with the second threaded hole 211 and pass through
Second grooving 212 of logical second threaded hole 211, the second-order pipe 22 are equipped with third grooving 225, the second-order pipe 22
Surface is equipped with several retaining rings 221, and the left end of the second-order pipe 22 is additionally provided with guide part 226, first grooving 12, the
Two groovings 212 and third grooving 225 are parallel with central axes and be mutually communicated, first grooving 12 and the second grooving 212
The both ends of end plate 1 and the first rank pipe 21 are extended through, the third grooving 225 is straight since from the left end of second-order pipe 22
Right end to second-order pipe 22 terminates, the equivalent width of first grooving 12 and the second grooving 212, the third grooving
For 225 width from right end to left end in the trend being gradually reduced, the surface of the first rank pipe 21 is additionally provided with several anti-skidding muscle
213, second-order pipe 22 is divided into upper half rank pipe with the third grooving 225 and lower half rank is managed, the upper half rank pipe and lower half rank
It is equipped with side elastic slice 222 on pipe, the retaining direction of the side elastic slice 222 and retaining ring 221 is preset with expansion tube insertion plate
It is contrary in hole, tie rod 223 is fixed on the side elastic slice 222.The tie rod 223 pass through end plate 1 on through-hole 13 with
Pulling plate 224 is connected.
The course of work of the present invention:
The present invention it is a kind of it is easily de- take expansion tube during the work time, drilled out on wall or plate first one it is preset
Then expansion tube is knocked in the guide part of expansion tube 226 in the preset holes being drilled towards preset holes by hole, then, then will
Screw screws in expansion tube along the first threaded hole 11 and the second threaded hole 211.With the insertion of screw, expansion tube is along first
It is gradually deformed outward at grooving 12, the second grooving 212 and third grooving 225 and spreading is to clamping preset holes.221 He of retaining ring
Side elastic slice 222 can be effectively prevented expansion tube and exit along the opposite direction of direction of insertion.Anti-skidding muscle 213 can be to avoid expansion
Pipe rotates in wall.When needing to take out expansion tube, firstly, taking out the screw in expansion tube, then pressed to central axes direction
Pulling plate 224 makes tie rod 223 that side elastic slice 222 be pulled to draw close it to central axes direction, then compresses end plate 1 to central axes direction,
So that expansion tube is gradually inwardly compressed at the first grooving 12, the second grooving 212 and third grooving 225, finally pull again swollen
Tube expansion out of wall so that pull out expansion tube.
The present invention passes through pressing by pulling pulling plate to make tie rod that side elastic slice be driven gradually to move to the direction close to central axes
End plate makes expansion tube along the first grooving, the second grooving and third grooving to contract, to avoid expansion tube when being drawn out
Side elastic slice and retaining ring resist preset holes, it is whole it is de- take easy, quickly, the efficiency of wall surface finishing can be effectively improved.
Above-described embodiment is the description of the invention, is not limitation of the invention, after any pair of simple transformation of the present invention
Scheme all belong to the scope of protection of the present invention.
