Example 1

As shown in fig. 1 and 2, the present embodiment provides a prefabricated part assembly 100, which includes a first prefabricated part 1 and a second prefabricated part 2, a temporary joint body 4 is provided between the first prefabricated part 1 and the second prefabricated part 2, and the first prefabricated part 1 and the second prefabricated part 2 are butt-jointed, installed and fixed by a plurality of butt-jointing pieces 3 arranged at intervals. As preferred technical scheme, a plurality of interfacing part 3 are arranged with two rows of multiseriate mode, of course, in the prefabricated component assembly 100 provided by the utility model, first prefabricated component 1 and second prefabricated component 2 by the interfacing part 3 butt joint installation of more than one interval arrangement can.

As shown in fig. 2, the interface element 3 in the present embodiment includes: an extension rib 31 extending out of the end of the first prefabricated part 1, a sleeve 32 embedded in the end of the second prefabricated part 2 and allowing the extension rib 31 to be partially inserted, a slip-off preventing mechanism 33 embedded in the sleeve 32 and reversibly locking the extension rib 31, and a detachable buckle cover 34 allowing the extension rib 31 to axially penetrate and covering the slip-off preventing mechanism 33 in the sleeve 32; the detachable buckle cover 34 includes a screwing section 341 at the temporary joint body 4, and the axial height of the screwing section 341 is greater than or equal to 2 mm to facilitate screwing work.

In the structure, the anti-release mechanism 33 is firstly installed in the sleeve 32, and then the detachable buckle cover 34 is screwed on the sleeve 32, so that the anti-release mechanism 33 cannot be released from the sleeve 32, when the first prefabricated component 1 and the second prefabricated component 2 are connected, the extension rib 31 penetrates through the detachable buckle cover 34 and the anti-release mechanism 33, and under the combined action of the anti-release mechanism 33 and the detachable buckle cover 34, the anti-release mechanism 33 can reversely clamp the extension rib 31, so that the connection between the first prefabricated component 1 and the second prefabricated component 2 is stable, and the requirement of the anti-pulling performance between the first prefabricated component 1 and the second prefabricated component 2 can be met.

The screwing section 341 of the detachable buckle cover 34 is exposed at the gap between the first prefabricated component 1 and the second prefabricated component 2, and the gap between the first prefabricated component 1 and the second prefabricated component 2 is filled with a joint mixture and cured to form a temporary joint body 4 to form a prefabricated component assembly 100; the temporary joint body 4 not only beautifies the joint between the first prefabricated part 1 and the second prefabricated part 2, but also plays a role in wind and water prevention and the like, when the first prefabricated part 1 and the second prefabricated part 2 need to be separated, the temporary joint body 4 is removed, a screwing tool matched with a screwing section 341 of the detachable buckle cover 34 extends into the gap, the detachable buckle cover 34 is screwed, after the detachable buckle cover 34 is screwed out of the sleeve 32 along the axial direction of the extension rib 31, the anti-release mechanism 33 loses the reverse blocking effect provided by the detachable buckle cover 34, the extension rib 31 can be directly pulled out from the sleeve 32 or the extension rib 31 drives the anti-release mechanism 33 to be pulled out from the sleeve 32 together, so that the first prefabricated part 1 and the second prefabricated part 2 are separated, therefore, the first prefabricated part 1 and the second prefabricated part 2 can be repeatedly dismounted and mounted for a plurality of times, and the screwing tool can be a wrench, the outer side surface of the screwing section 341 of the detachable buckle cover 34 is matched with a wrench, and the detachable buckle cover 34 and the sleeve 32 can be in threaded connection. To ensure that the removable cover 34 can be screwed out of the sleeve 32 and into the gap between the first prefabricated part 1 and the second prefabricated part 2, the width W of the temporary joint body 4 is greater than the axial length L1 of the removable cover 34.

Since, during the assembly of the first prefabricated element 1 and the second prefabricated element 2, as the first prefabricated element 1 and the second prefabricated element 2 approach each other, after the extension rib 31 penetrates through the detachable buckle cover 34 and the anti-slip mechanism 33, the extension rib 31 will extend into the sleeve 32, the anti-slip mechanism 33 will move together with the extension rib 31 in the direction away from the detachable buckle cover 34 until the end surface of the first prefabricated component 1 abuts against the end surface of the second prefabricated component 2, or the end of the extension rib 31 is pressed against the bottom of the sleeve 32, at this time, a certain movable clearance exists between the anti-drop mechanism 33 and the detachable buckle cover 34, when the prefabricated member 2 is pulled out, the second prefabricated member 2 has a movement margin with the same size as the movement gap (namely, after the second prefabricated member 2 is pulled out upwards for a certain distance, the butt joint part 3 can realize the reverse clamping function), so that the connection between the first prefabricated member 1 and the second prefabricated member 2 is unstable.

As shown in fig. 2 and 3, in order to avoid the above situation, the middle section of the extension rib 31 in this embodiment is a threaded section, and the locking nut 8 is screwed on the threaded section. When the first prefabricated part 1 and the second prefabricated part 2 are assembled, if the extension rib 31 passes through the anti-release mechanism 33 and the detachable buckle cover 34, and the end surface of the locking nut 8 does not abut against the end surface of the screwing section 341 of the detachable buckle cover 34, the second prefabricated part 2 is lifted upwards, so that the movable gap between the extension rib 31, the anti-release mechanism 33 and the detachable air conditioner 34 is eliminated, and then the locking nut 8 is screwed, so that the end surface of the locking nut 8 abuts against the end surface of the screwing section 341 of the detachable buckle cover, and at this time, the extension rib 31 cannot continue to extend into the sleeve 34 due to the blocking effect of the locking nut 8, so that the movable gap of the butt joint part 3 is eliminated. In addition, if the extension rib 31 does not pass through the anti-drop mechanism 33 and the detachable buckle cover 34, the end surface of the locking nut 8 abuts against the end surface of the screwing section 341 of the detachable buckle cover 34, and at this time, the locking nut 8 is screwed, so that the extension rib 31 can continue to extend into the sleeve 34 until the extension rib 31 passes through the anti-drop mechanism 33 and the detachable buckle cover 34. In this embodiment, the outer circumferential contour of the locking nut 8 is preferably identical or similar to the outer contour of the screw section 341, which facilitates the use of the same screw tool.

Since the first prefabricated part 1 and the second prefabricated part 2 have an assembly gap which cannot be eliminated after assembly, a series of phenomena such as water leakage and/or air leakage may occur, and the metal butt connector 3 may be corroded to affect the connection stability and durability, the gap filler is filled in the assembly gap between the first prefabricated part 1 and the second prefabricated part 2, and the temporary joint body 4 is formed after solidification. In addition, in order to avoid water and air permeation at the position of the bump 5, in the embodiment, the wall thickness of the bump 5 can be designed to be smaller than that of the prefabricated part, so that the joint mixture can be conveniently filled at the abutting part of the bump and the prefabricated part. In this embodiment, the joint mixture may be foam rubber, glass cement, pointing cement, caulking gypsum, or the like.

In addition, because the first prefabricated component 1 or the second prefabricated component 2 needs to be lifted when the first prefabricated component 1 and the second prefabricated component 2 are assembled, the first prefabricated component 1 or the second prefabricated component 2 can shake after being lifted, the end part of the first prefabricated component 1 or the second prefabricated component 2 is easy to collide, and the surface of the first prefabricated component 1 or the second prefabricated component 2 is damaged, and therefore a protective hoop is coated on the end part of the first prefabricated component 1 and/or the end part of the second prefabricated component 2 to protect the first prefabricated component 1 and/or the second prefabricated component 2. In addition, because the requirement of the abutting part 3 in the embodiment on pulling resistance and pressure resistance is not very high when the abutting part is applied to low-rise buildings, the ratio of the maximum outer diameter of the detachable buckle cover 34 to the axial length of the detachable buckle cover 34 is preferably 1: 2-5: 1.

Further, as shown in fig. 3, in order to reinforce the structural strength of the first prefabricated part 1 and the second prefabricated part 2, the first prefabricated part 1 and the second prefabricated part 2 are embedded with stress bars 6.

As shown in fig. 4, in order to avoid separation of the sleeve 32 from the second prefabricated part 2, the sleeve 32 may be formed by drilling the end of the stress rib 6. In the present embodiment, the sleeve 32 having the locking platform 321 formed at one end thereof is axially fitted over the stress bar 6, and the locking platform 321 is locked to the enlarged end 61 formed by upsetting the end of the stress bar 6 in the opposite direction, so that the sleeve 32 is connected to the stress bar 6. Preferably, the sleeve 32 and the stress bar 6 can be embedded in the second prefabricated part 2 together, so that the concrete on the end surface of the second prefabricated part 2 is prevented from being crushed due to the compression of the sleeve 32.

Furthermore, in the present embodiment, one end of the extension rib 31 is connected and fixed to the end of the stress rib 6 in the first prefabricated component 1 through the adapter 7.

In the above structure, the connection mode of the adapter 7 and the stress bar 6 can be the same as the connection mode of the sleeve 32 and the stress bar 6. The adapter 7 can also be embedded in the first prefabricated part 1 together with the stress bar 6. Extension muscle 31 and adapter 7 between can be through threaded connection, consequently can be after first prefabricated component 1 shaping or when first prefabricated component 1 and second prefabricated component 2 assembly, in avoiding extension muscle 31 in transportation or hoist and mount in-process to bump and lead to the damage in the adapter 7 again.

Specifically, in this embodiment, the exposed end of the extension rib 31 has a reducing plug 311 that can extend into the sleeve 32, and the rod of the extension rib 31 is transitionally connected to the reducing plug 311 by a plug neck 312, where the plug neck 312 is a portion having an outer diameter smaller than the outer diameter of the rod and the outer diameter of the reducing plug 311.

Furthermore, as shown in fig. 3, the anti-slip mechanism 33 includes an annular locking body 332 covered in the sleeve 32 by the detachable cover 34, and an elastic element 333 which is disposed in the sleeve 32 and pushes the annular locking body 332 toward the detachable cover 34; wherein, the detachable buckle cover 34 is provided with an inner conical blocking surface 342 facing the annular blocking body 332, after the reducing plug connector 311 sequentially penetrates through the detachable buckle cover 34 and the annular blocking body 332, the annular blocking body 332 is blocked and connected with the plug neck 312.

In the above structure, when the first prefabricated component 1 and the second prefabricated component 2 are assembled, after the extension rib 31 is inserted into the sleeve 32, the tapered plug 311 of the extension rib 31 penetrates through the detachable buckle cover 34 and the annular locking body 332, and then the annular locking body 332 locks the plug neck 312, when the extension rib 31 is pulled outwards, the tapered plug 311 drives the annular locking body 332 to have a tendency of moving outwards, and because the detachable buckle cover 34 is provided with the inner tapered blocking surface 342 towards the annular locking body 332, when pulled, the inner tapered blocking surface 342 blocks the annular locking body 332, the extension rib 31 cannot be pulled out of the sleeve 32, and the first prefabricated component 1 and the second prefabricated component 2 are firmly connected. When the first prefabricated part 1 and the second prefabricated part 2 are disassembled, a screwing tool is inserted between the first prefabricated part 1 and the second prefabricated part 2, after the detachable buckle cover 34 is screwed out of the sleeve, the annular clamping bodies 332 lose the blocking effect of the inner conical blocking surfaces 342, after the first prefabricated part 1 is lifted, the extension ribs 31 can be directly pulled out of the sleeve 32, or the sleeve 32 can be pulled out together with the annular clamping bodies 332, so that the first prefabricated part 1 and the second prefabricated part 2 are separated.

Furthermore, as shown in fig. 5, in the present embodiment, the annular locking body 332 has four arc-shaped blocks 3321 that are sequentially connected end to form a central through hole.

In the above structure, when the first prefabricated component 1 and the second prefabricated component 2 are assembled, the extension rib 31 is inserted into the sleeve 32, the reducing plug connector 311 abuts against the end surface of the annular clamping body 332, after the reducing plug connector 311 pushes the annular clamping body 332 to slide down for a certain distance, the annular clamping body 332 stops sliding down under the action of the elastic element 333, after the reducing plug connector 311 penetrates through the central through hole and spreads the annular clamping body 322, each arc-shaped fixture block 3321 is pushed by the elastic element 333, so that each arc-shaped fixture block 3321 is reset and gathered at the neck insert 312 along the inner cone-shaped blocking surface 342 again, and each arc-shaped fixture block 3321 is blocked by the inner cone-shaped blocking surface 342 of the detachable buckle cover 34, so that the extension rib 31 cannot be pulled out of the sleeve 32. In order to allow the arc-shaped fixture block 3321 to be better restored and gathered under the action of the elastic element 333, it is preferable that the arc-shaped fixture block 3321 has a slope surface matched with the inner tapered blocking surface 342. When drawing extension muscle 31, there is great extrusion force between the muffler 312 of extension muscle 31 and the arc fixture block 3321, thereby when extension muscle 31 bears the drawing power, muffler 312 has the trend that drives arc fixture block 3321 upward movement, the trend that further presss from both sides tight arc fixture block 3321 exists in dismantlement formula buckle closure 34's interior toper fender surface 342 this moment, make dismantlement formula buckle closure 34 exert the radial extrusion force that gives arc fixture block 3321 also increase simultaneously, make the clamping-force of arc fixture block 3321 centre gripping muffler 312 bigger, annular card body 322 that can't pass more to reducing bayonet joint 311, avoid extension muscle 31 to be extracted sleeve 32.

In addition, since the annular locking body 332 needs to be pushed by the elastic element 333 and the annular locking body 332 is spread into the arc-shaped blocks 3321 after the reducer plug 311 penetrates through the annular locking body, the arc-shaped blocks 3321 are easy to fall or topple, and therefore the support plate 335 for supporting the annular locking body is arranged between the annular locking body 332 and the elastic element 333. Preferably, the elastic member 333 is a spring.

The embodiment also provides a fabricated building, which includes the prefabricated component assembly 100, and can be used for forming a wall of the fabricated building.

Example 2

In this embodiment, the same portions as those in embodiment 1 are given the same reference numerals, and the same description is omitted.

In this embodiment, instead of the locking nut 8, another embodiment is adopted to prevent the extension rib 31 from excessively extending into the sleeve 32, as shown in fig. 6, 7 and 8, the end of the first prefabricated component 1 and/or the second prefabricated component 2 is provided with more than two detachable projections 5 at intervals; wherein the butt-joint piece 3 is positioned between two adjacent lugs 5.

In the above structure, when the first prefabricated part 1 and the second prefabricated part 2 are assembled, after the extension rib 31 passes through the detachable buckle cover 34 and the anti-falling mechanism 33, the first prefabricated part 1 and the second prefabricated part 2 continue to approach each other, and at this time, the protrusion 5 can block the first prefabricated part 1 or the second prefabricated part 2 and prevent the extension rib 31 from excessively extending into the sleeve 32, so that a large moving gap is prevented from being generated on the joint 3. If the extension rib passes through the detachable buckle cover 34 and the anti-falling mechanism 33 when the end surface of the bump 5 is not abutted with the end surfaces of the first prefabricated part 1 and the second prefabricated part 2, the second prefabricated part 2 is lifted upwards, the movable gap among the extension rib 31, the anti-falling mechanism 33 and the detachable air conditioner 34 is eliminated, and the temporary joint body 4 is formed after the filled joint mixture is cured, so that the movable gap between the first prefabricated part 1 and the second prefabricated part 2 is eliminated. Furthermore, in order to form a space between the first prefabricated part 1 and the second prefabricated part 2 for enabling the detachable buckle cover 34 to be detached from the sleeve 32, after the first prefabricated part 1 and the second prefabricated part 2 are connected, the lugs 5 support the first prefabricated part 1 or the second prefabricated part 2, so that a larger construction distance is formed between two adjacent lugs 5. At this time, the abutting piece 3 is located between two adjacent projections 5. In addition, since the top surface of the bump 5 becomes a bearing surface and is easily crushed and broken after the bump 5 supports the first block 1 or the second block 2, the bump 5 can be set in a detachable manner and the broken bump 5 can be replaced.

In this embodiment, the bump 5 may be a concrete structure, a metal block, or a reinforced concrete structure. Of course, the projection 5 can also be integrally formed with the end of the first prefabricated part 1 and/or the end of the second prefabricated part. In addition, the projection value L2 of the projection 5 may be smaller than or equal to the slit width W of the temporary joint body 4.

Example 3

In this embodiment, the same portions as those in embodiment 2 are given the same reference numerals, and the same description is omitted.

As shown in fig. 9, in the present embodiment, the annular locking body 332 is an integral body, and four radial grooves 3322 are opened on the inner peripheral wall of the annular locking body 332 around the central axis.

In the structure, when the first prefabricated component 1 and the second prefabricated component 2 are assembled, the extension rib 31 is inserted into the sleeve 32, after the reducing plug connector 311 passes through the detachable buckle cover 34, the reducing plug 311 abuts against the end surface of the annular locking body 332, after the reducing plug 311 pushes the annular locking body 332 to slide downwards for a certain distance, the annular locking body 332 stops sliding downwards under the action of the elastic element 333, when the extension rib 31 continues to apply an axial pushing force and/or a radial pushing force away from the central axis to one end surface of the annular locking body 332, the annular clamping body 332 is split into four independent arc-shaped blocks at the radial groove 3322, after the reducing plug connector 311 penetrates through the split annular clamping body 332, each arc-shaped block is reset and gathered at the position of the inserting neck 312 along the inner conical blocking surface 342 under the pushing action of the elastic element 333 so as to reversely block the reducing inserting head 311, so that the extension rib 31 cannot be pulled out of the sleeve 32.

Example 4

As shown in fig. 10 and 11, in the present embodiment, the annular locking body 332 includes an annular bottom plate 3323 and an annular clamping body 3324 which are integrally formed (i.e., the annular bottom plate 3323 and the annular clamping body 3324 are integrally cast); the annular clamping body 3324 has eight clamping jaws 33241 spaced around the central axis of the annular bottom plate 3323, wherein the clamping jaw 33241 has a claw portion 33241a and an elastic connecting piece 33241b, and the elastic connecting piece 33241b extends from the annular bottom plate 3323 to the detachable buckle cover 34 to engage with the claw portion 33241a.

In the above structure, when the first prefabricated component 1 and the second prefabricated component 2 are assembled, the extension rib 31 is inserted into the sleeve 32, after the variable-diameter plug connector 311 penetrates through the detachable buckle cover 34, the variable-diameter plug connector 311 pushes the annular clamping body 332 to slide downwards for a certain distance, the annular clamping body 332 stops sliding downwards under the action of the elastic element 333, then the elastic connecting pieces 33241b are radially expanded when the variable-diameter plug connector 311 penetrates through the claw portions 33241a, and when the variable-diameter plug connector 311 passes through the claw portions 33241a, the elastic connecting pieces 33241b are radially reset so that the claw portions 33241a are gathered at the plug neck 312 position to reversely clamp the variable-diameter plug connector 311. After the assembly is completed, the claw portion 33241a is abutted by the inner tapered stop surface 342 of the removable cover 34, so that the extension rib 31 cannot be pulled out of the sleeve 32. When the extension rib 31 is pulled, a larger pressing force exists between the collar 312 and the claw 33241a of the extension rib 31, so that when the extension rib 31 bears a pulling force, the collar 312 has a tendency of driving the claw 33241a to move upwards, and at this time, the inner conical blocking surface 342 of the detachable buckle cover 34 has a tendency of further clamping the claw 33241a, so that the radial pressing force applied to the claw 33241a by the detachable buckle cover 34 is increased, the clamping force of the claw 33241a clamping the collar 312 is larger, the reducing plug 311 cannot penetrate through the annular clamping body 322, and the extension rib 31 is prevented from being pulled out of the sleeve 32.

In addition, during assembly, when the reducer plug 311 abuts against the claw portion 33241a, the elastic connecting piece 33241b may not be radially expanded but may be pressed and bent toward the central axis, so that the reducer plug 311 cannot penetrate the claw portion 33241a, and therefore, a guide surface 33241c inclined toward the central axis is provided on the top of the claw portion 33241a.

Example 5

As shown in fig. 12 and 13, in the present embodiment, the disengagement preventing mechanism 33 includes an elastic clamping portion 331 integrally formed with the detachable buckle cover 34 (i.e., the detachable buckle cover 34 and the elastic clamping portion 331 are integrally cast); the elastic clamping portion 331 has three or more elastic pieces 3311 spaced around the central axis of the detachable buckle cover 34, and the elastic pieces 3311 are gradually gathered radially in the insertion direction of the extension rib 31.

In the above structure, when the first prefabricated component 1 and the second prefabricated component 2 are assembled, the extension rib 31 is inserted into the sleeve 32, the reducing bayonet 311 radially expands the originally gathered elastic pieces 3311 when passing through the elastic clamping portion 331, and when the reducing bayonet 311 passes over the elastic clamping portion 331, the elastic pieces 3311 radially return to gather at the position of the collar 312 to reversely block the reducing bayonet 311. When the first prefabricated component 1 and the second prefabricated component 2 are disassembled, the detachable buckle cover 34 is screwed out of the sleeve 32, the detachable buckle cover 34 and the elastic clamping part 331 are sleeved on the extension rib 31 together, and the detachable buckle cover 34 and the extension rib 31 can be pulled out from the sleeve 32 together. After the detachable cover 34 is pulled out of the sleeve 32 together with the extension rib 31, the extension rib 31 is screwed out from the adapter 7, and the detachable cover 34 can be taken out from the other end of the extension rib 31 for secondary use. Or the detachable buckle cover 34 and the extension rib 31 can be screwed into the sleeve 32 together directly at the next assembly without screwing out the extension rib 31.

Example 6

As shown in fig. 14 and 15, in this embodiment, the extension rib 31 is an extended portion of the stress rib 6 in the first prefabricated component 1 (i.e. the extension rib 31 is a straight bar shape integrated with the stress rib), and the detachable buckle cover 34 is provided with a tapered channel 343 with a gradually increasing aperture along the insertion direction of the extension rib 31; the anti-slip mechanism 33 comprises a tightening part 334 covered in the sleeve 32 by the detachable buckle cover 34 and an elastic element 333 which is arranged in the sleeve 32 and pushes the anti-slip mechanism 33 to the detachable buckle cover 34; the tightening member 334 includes two or more arc-shaped clamping blocks 3341 that are fitted to the tapered channel 343 (i.e., the generatrix of the profile of the tapered channel 343 is parallel or substantially parallel to the generatrix of the profile of the arc-shaped clamping block 3341) and arranged in sequence along the circumferential direction.

In the above structure, the tightening member 334 includes a profile generatrix matching the tapered channel 343, i.e., the profile generatrix of the tapered channel 343 is parallel or substantially parallel to the profile generatrix of the arc-shaped holding block 3341. When first prefabricated component 1 and the assembly of second prefabricated component 2, extension muscle 31 inserts sleeve 32, extension muscle 31 promotes to tighten part 334 and slides down a section distance back along toper passageway 343, tighten part 334 under the effect of elastic element 333, the back that stops sliding down, extension muscle 31 can strut originally and gather together the arc grip block 3341 at toper passageway 343 and insert sleeve 32 with the forward, and after extension muscle 31 accomplished the insertion action, each arc grip block 3341 can gather together with reverse locking extension muscle 31 along toper passageway 343 under the effect of elastic element 333. In addition, since the extension rib 31 has a straight bar shape, in order to allow the tightening member 334 to lock the extension rib 31 well, the axial dimension of the tightening member 334 is slightly smaller than that of the tapered passage 343, so as to increase the contact area between the tightening member 334 and the extension rib 31. When drawing extension muscle 31, there is great frictional force between extension muscle 31 and the arc grip block 3341, thereby when extension muscle 31 bears the drawing force, extension muscle 31 has the trend that drives arc grip block 3341 upward movement, the toper passageway 343 of dismantlement formula buckle closure 34 has the trend of further pressing from both sides tight arc grip block 3341 this moment, make toper passageway 343 apply for tightening the radial extrusion force of part 334 also increase simultaneously, make the clamping-force of tightening part 334 centre gripping extension muscle 31 bigger, avoid extension muscle 31 to be extracted sleeve 32.

In addition, the insertion passage formed when the arc-shaped holding blocks 3341 are gathered is substantially tapered in the insertion direction of the extension rib 31. After extension muscle 31 inserts, tighten the bottom of part 334 and provide the great extrusion force of extension muscle 31 earlier, when drawing extension muscle 31, arc grip block 3341 leans out earlier, arc grip block 3341's top earlier with the medial surface contact of dismantlement formula buckle closure 34, consequently the radial extrusion force in arc grip block 3341 top is applyed earlier for toper passageway 343 and makes it press from both sides tight extension muscle 31, give the radial extrusion force in arc grip block 3341 bottom afterwards again, thereby make extension muscle 31's resistance to plucking ability obtain further promotion. Of course, in order to provide a larger frictional force between the extension rib 31 and the arc-shaped holding block 3341, the inner wall of the arc-shaped holding block 3341 and/or the outer surface of the extension rib 31 may be further surface-treated by knurling or knurling process or tooth-biting process.

Furthermore, the outer peripheral surface of the arc-shaped clamping block 3341 is provided with a circumferential groove 33411, when the arc-shaped clamping blocks 3341 are mutually enclosed and axially flush, the circumferential grooves 33411 are circumferentially aligned, and at least one elastic hoop is embedded in the circumferential groove 33411, and in the case of a plurality of elastic hoops, the elastic hoops can be axially stacked and/or radially nested in multiple layers. It should be noted that the elastic band in this embodiment is not an essential component, but the elastic band can be provided to ensure that the arc-shaped holding blocks 3341 can be restored and gathered more quickly and effectively by exerting a radial restraining force.
