The tensioning sleeve 814 is made of rubber material, the tensioning sleeve 814 is sleeved on the outer sleeve 803, and one side end face of the tensioning sleeve 814 is supported on the upper surface of the positioning block 7. A plurality of groups of tightening components are arranged between the outer ring walls of the outer sleeve 803 and the inner hole wall of the tensioning sleeve 814, each group of tightening components can be tightly tightened in the tensioning sleeve 814 along with the rotation of the outer sleeve 803, so that the tensioning sleeve 814 can be tightened in the assembly hole corresponding to the external platform, the tensioning mode is that the tensioning sleeve 814 is expanded or deformed to a certain degree, the purpose of stable connection with the hole wall of the corresponding assembly hole is realized, and compared with the traditional bolt or bolt connection mode, the fault tolerance is higher; because when assembling external platform earlier, hoist and mount external platform on supporting framework 1, need behind the very accurate alignment bolt of pilot hole and the bolt, just can carry out further assembly operation, the precision requirement of whole assembly process is higher, is very difficult to operate and examines operator's proficiency. And after the connecting piece of this application is adopted, the mounting hole of the outside platform that only needs to hoist roughly aims at tensioning sleeve 814 and can carry out further locking operation after cartridge smoothly, and whole assembling process has improved convenient degree to the requirement greatly reduced of precision and operation proficiency.

In this embodiment, the tightening assembly includes a first connecting rod 810, a second connecting rod 811 and a supporting plate 807, the outer sleeve 803 is sleeved with a first collar 812 and a second collar 813, the first collar 812 is in a form of a screw sleeve and is screwed with the outer sleeve 803, the second collar 813 is rotatably connected with the outer sleeve 803 through a bearing, the middle portions of the first connecting rod 810 and the second connecting rod 811 are hinged to each other, and both ends of the first connecting rod 810 are respectively hinged with one end of the supporting plate 807 and the first collar 812 through a pin hinge seat, which is a pin hole machined on a common seat body, and a rotating pin is rotatably fitted in the pin hole. Similarly, the second link 811 is hinged at both ends thereof to the other end of the stay plate 807 and the second collar 813 by a pin hinge.

It should be noted that the hinge holes (pin holes) on the pin hinge between the first connecting rod 810 and the first collar 812 and the pin hinge between the second connecting rod 811 and the supporting plate 807 are strip holes, which means that the pin hinge here is divided into two types, i.e. the first pin hinge 809 and the second pin hinge 808, the hinge hole on the second pin hinge 808 is a circular hole, the hinge hole on the first pin hinge 809 is a strip hole, and the rotating pin can move in the strip hole, so that the smooth radial movement of the supporting plate 807 relative to the tensioning sleeve 814 can be ensured. In addition, in the same fastener, two first pin sockets 809 are located in the same radial direction (of the tensioning sleeve 814) and two second pin sockets 808 are located in the same radial direction (of the tensioning sleeve 814), so that when the first sleeve 812 rotates relative to the outer sleeve 803, the included angle between the first link 810 and the second link 811 in the bracket can be changed, thereby achieving the purpose of radial movement of the bracing plate 807. Certainly, in order to smoothly enable the supporting plate 807 to move radially, a certain limit needs to be performed on the supporting plate 807, specifically, a T-shaped sliding groove 821 is processed on a side wall of the positioning block 7 close to the tensioning sleeve 814, the T-shaped sliding groove 821 is arranged along the radial direction of the tensioning sleeve 814, one end of the supporting plate 807 is provided with a sliding part in sliding fit with the T-shaped sliding groove 821, the sliding part is designed to limit the supporting plate 807 to a moving range which can only move radially, so that when the outer sleeve 803 rotates, the second sleeve ring 813 cannot move axially relative to the outer sleeve 803, and at this time, the first sleeve 812 can move axially relative to the outer sleeve 803 under the effect of thread connection, so that the supporting plate 807 can smoothly slide radially along the direction of the T-shaped sliding groove 821.

In this embodiment, the clamping portion 819 that can extend to the outer sleeve 803 is formed at the end of the clamping block 818 away from the limiting head 816, the side of the clamping portion 819 away from the central axis of the outer sleeve 803 is an inclined surface 820, one end of the inclined surface 820 away from the limiting head 816 inclines toward the side close to the central axis of the outer sleeve 803, when the lower port of the assembling hole contacts the inclined surface 820 of the clamping portion 819, through the effect of the inclined surface cut-and-shut, all the clamping blocks 818 can be gathered toward the central axis of the outer sleeve 803, and therefore the purpose that the assembling hole is sleeved on the outer sleeve 803 is smoothly achieved. The assembly hole is in the form of a through hole, can be a straight hole, and can also be in the form of a secondary step hole (with a small upper part and a large lower part), wherein the latter is adopted. The inner sleeve 806 is driven to move, the limiting head 816 acts on one end of the snap-in block 818, the clamping portion 819 of the snap-in block 818 can rotate towards one side far away from the central axis of the outer sleeve 803, and the purpose that the clamping portion 819 and the upper end wall of the assembly hole are pressed tightly is achieved. Specifically, a frustum-shaped limiting sunk groove 817 is processed on one side of the limiting head 816 close to the buckling block 818, the diameter expansion end of the limiting sunk groove 817 is close to the buckling block 818 to drive the inner sleeve 806 to move, the limiting head 816 acts on the lower end of the buckling block 818 to enable the side groove wall of the limiting sunk groove 817 to act on one side of the lower end of the buckling block 818 far away from the central axis of the outer sleeve 803, the lower end of the buckling block 818 can rotate towards one side close to the central axis of the outer sleeve 803, and finally the purpose of mutually and stably compressing all the buckling parts 819 and the upper end wall of the assembly hole is achieved.

In order to facilitate the easy separation of the clamping portions 819 from the upper end wall of the assembly hole during the disassembly, a core bar 805 is screwed in the inner hole of the inner sleeve 806, one end of the core bar 805 penetrates into the limiting sunk groove 817 and is formed with a push head 815, the core bar 805 is rotated, the push head 815 acts on one end of the snap-in block 818, the clamping portion 819 of the snap-in block 818 can be rotated towards one side close to the central axis of the outer sleeve 803, specifically, the push head 815 is in a frustum shape, the reduced-diameter end of the push head 815 is close to the snap-in block 818, the reduced-diameter end of the push head 815 acts on one side of the snap-in block 818 close to the central axis of the outer sleeve 803, the lower end of the snap-in block 818 can be rotated towards one side far away from the central axis of the outer sleeve 803, so that all the clamping portions 819 are folded and can be smoothly separated from the assembly hole.
