When the line is tired, the screw rod 91 which has been sleeved with the expansion sleeve 92 and the nuts 93 and 94 is first placed in the wall hole 9 (), and the nut % is rotated to drive the movement of the screw Q 1 to make the screw The tapered portion 912 on the hinge 91 pushes the expansion sleeve 922 to select it, thereby achieving the effect of the cartridge's positioning in the wall hole. The known expansion screw kit relies entirely on the expansion of the expansion sleeve 92 to 峑a: the bore 9 〇 inside to achieve the purpose of locking. For this reason, whether the expansion screw is solid or solidly stuck in the wall hole 90, and whether the expansion sleeve of the expansion sleeve 92 is enough to be completely stuck in the wall hole 9 is a heavy-sounding factor. (4) The effect of the expansion and extensibility of the intestine casing 92 of the expansion screw kit (4). In the rolling eye, the conventional expansion screw kit has the disadvantage that it is not easy to remove after use. The expansion sleeve usually causes permanent deformation after expansion, and even if it is pulled out from the hole, it can no longer be used. [New content] The swelled membrane screw kit of this creation includes a screwing rod, a nut, and an expansion sleeve. The screwing rod includes a threaded section, and the bottom end of the screw is formed with an outwardly expanding tapered portion. The nut is screwed out of the screwing rod. (4) The pushing sleeve is screwed on the screwing rod and located at the screw Between the cap and the threaded rod of the screw. The push sleeve includes a tapered portion. The expansion sleeve includes an independent plurality of sleeve pieces, surrounding the screwing rods, each of which is formed on the inner side with a front end flared slope and a rear end flared slope, wherein: The outer surface of the push rod abuts against the flared portion of the screwing rod. After the expansion of the above expansion screw package, the above expansion screw kit design, even if it has been used, it can be easily removed and reused afterwards. The pushable sleeve can extend from the inside of the expansion sleeve. Expansion screw sleeve white: L-auxiliary rotation tool 'auxiliary rotation tool' includes - grip portion and movement 2: one of the protrusions of the crotch end protrusion, with which the auxiliary rotation tool can easily rotate the push-up sleeve to advance along the thread segment, Retreating, for example, the top end of the pushing sleeve M396337 may be recessed with an operating slot for the above-mentioned protrusion to be inserted and rotated. The top end of the screwing cymbal can be recessed with an operation slot. When the expansion screw kit is to be disassembled, in order to prevent the ejector pin from being idling together with the screwing rod, a long column can be passed through the auxiliary rotating device and pressed against the operating slot. Apply force to the top push sleeve to rotate smoothly back. The above expansion screw kit may further include a cymbal piece disposed between the nut and the push sleeve _ [Embodiment] Referring to Figures 3 to 5. An expansion screw kit is shown in Fig. 3 and includes a screw shank, an expansion sleeve 12, a push sleeve 13, a nut 14, a spacer 15, and an auxiliary rotator 16. The screw rod 丨丨 includes a thread segment η!, in this example, the thread segment (1) starts from the end of the screw rod (10) and occupies at least two-thirds of the length of the screw rod u; the thread segment lu is followed by a small section smoothing. The segment (1) and the outer flared portion 112 and the palpear flared portion 112 are formed at the bottom end of the screw 11. (4) The sleeve 12 is composed of a plurality of independent sleeve pieces 121. In this example, the number of the sleeve pieces 121 is three, of course not limited thereto, and may be two, or four, five or even More pieces are formed. A plurality of sleeve pieces m are arranged around the circumference of the screw, and each of the sleeve pieces ΐ2i has a front end expansion inclined surface 122 and a rear end expansion slope surface 123 on the inner side surface, that is, the two ends are located at both ends. The slopes are all axially outward and outward. The pushing sleeve 13, the nut 14, and the spacer 15 are all sleeved in the screwing rod η, wherein the pushing sleeve 13 and the nut 14 are screwed to the top of the threaded rod u thread segment 5 M396337 and self-expanding The inside of the sleeve 12 extends outwardly. The thrust sleeve 13 is disposed between the nut 14 and the flared portion 112 of the screw rod, and the gasket 15 is interposed between the nut 14 and the thrust sleeve 13. The push sleeve 13 includes a continuous section 130 and a tapered taper 131. The operating screw kit of the present invention is described below. Firstly, before the expansion screw kit is placed, for example, in a wall hole, the expansion sleeve 12 can be coupled to the screw rod 1 in any suitable manner, for example, by strap binding or simple bonding means to provide a basic The force is applied to the plurality of sleeve sheets 121, and then the screwing rod 11 (the screwed push sleeve 13) can be placed in the wall hole 20 together with the expansion sleeve 12. Next, the thrust sleeve 13 is rotated to gradually advance along the thread segment. In this example, an auxiliary rotating tool 16 is used. The auxiliary rotator 16 includes a grip portion 161 for gripping operation and a pair of projections 162 projecting from the bottom end of the grip portion 161. As long as the two protrusions 162 are correspondingly inserted into the recess of the top end of the pushing sleeve 13 (in this embodiment, the top end of the pushing sleeve 13 is directly processed into the in-line operation groove 132), and then the auxiliary rotating tool 16 can be rotated by hand. The push sleeve 13 is driven to rotate forward as shown in FIG. During the rotation of the thrust sleeve 13, the thrust sleeve 13 will pass through, and the tapered portion 131 gradually pushes the front end of the sleeve body 121 outwardly to expand the inclined surface 122, so that the front end of the sleeve piece 121 is radially and relatively slippery. shift. After the front end of the sleeve piece i2i is moved to a certain extent, the cymbal 15 and the nut 14 are sequentially assembled into the screwing rod 11, and then the nut 14 is rotated (a general screwdriver can be used) to expand the screw rod. The manner in which the tapered portion 112 gradually approaches the nut 14 produces relative movement. At this time, the flared portion 112 gradually pushes up the slanting surface M396337 123 of the ferrule body 121 to cause a radial relative slip at the rear end of the ferrule body 121. At this point, each of the sleeve bodies 121 is radially outwardly slid and expanded to achieve the purpose of the holes 20, as shown in Fig. 5. When the expansion screw kit is to be removed, the nut 14 and the cymbal 15 are first removed according to the reverse steps described above, and the urging tool 16 is used to reversely rotate the urging sleeve η to gradually no longer apply the ferrule piece. The body i2i, in the end, each of the sleeve pieces 121 is radially inwardly retracted and retracted without permanent deformation. It can be seen from the above that the present invention utilizes a plurality of independent sleeve bodies 121 as climbing expansion sleeves, which are respectively driven by the tapered surface of the thrust push sleeve U and the taper surface of the screwing correction, and are carried out by mobile expansion. Non-deformable expansion, so it can still be recycled, saving material costs, and achieving environmental protection. In the above embodiment, the top end of the screwing rod U is further recessed - an operation groove 4 (for example, a letter groove). When the top push sleeve ^ is removed, if the screwing rod I is encountered, the rotation of the screw rod can be taken, and the long column can be passed through the auxiliary rotating device to be pressed into the groove H4, and the reverse force can be used. The pushing sleeve 13 smoothly rotates back, that is, it does not idle with the screwing rod u. The description of the embodiments is merely for convenience of description, and the scope of the claims is intended to be based on the scope of the patent application, and is not limited to the above embodiments.
