when the distance between the two limiting segments 28 needs to be adjusted, the default premise is that the two adjacent connecting pieces 1 are installed, at the moment, the extrusion part 279 extrudes the two sliding shafts to be far away from each other, at the moment, the sliding rod 280 is rotated to synchronously drive the first bevel gear 291 to rotate and drive the second bevel gear 294 to rotate, and the rotation of the second bevel gear 294 drives the lead screw 293 to rotate and drives the lead screw 293 to drive the limiting segments 28 to move towards each other or away from each other, so that the distance between the two limiting segments 28 is adjusted; it should be noted that, in this embodiment, the pressing portion 279 is formed by two partially overlapped cams (similar to an ellipse), so that the pressing of the sliding shaft can be maintained when the sliding rod 280 rotates, and the trapezoidal clamping block 23 is prevented from shrinking in the groove 21 when the sliding rod 280 rotates; in addition, the adjusting unit 29 can be used for detaching two adjacent connecting pieces 1, when the trapezoidal clamping blocks 23 are required to be retracted into the grooves 21 to detach two adjacent connecting pieces 1, only the sliding rod 280 is required to be pulled outwards, at this time, the extruding part 279 leaves between two sliding shafts, under the elastic action of the compression spring 278, the trapezoidal clamping blocks 23 are contracted in the grooves 21, meanwhile, the mounting frame 292 moves along with the movement of the sliding rod 280, and synchronously drives the screw rod 293 and the movable barrel 295 to move along with the movement, and at this time, the movable barrel 295 slides in the limiting sliding groove 296, that is, the first bevel gear 291, the mounting frame 292, the screw rod 293, the second bevel gear 294 and the movable barrel 295 can synchronously move in the direction perpendicular to the rotating limiting piece 2, so that the first bevel gear 291 and the second bevel gear 294 are kept in an engaged state, and the switching and independent working of two working states are facilitated; the sliding rod 280 is pulled outwards to realize quick disassembly of two adjacent connecting pieces 1, the sliding rod 280 is rotated to adjust the length of the rotation limiting piece 2, so that two kinds of work are mutually matched and independent, meanwhile, the screw rod 293 also has a self-locking function, if the sliding rod 280 is rotated by no external force, the screw rod 293 cannot rotate, even if the two sliding shafts extrude the extruding part 279, the screw rod 293 cannot be driven to rotate, and the accuracy can be further improved by adjusting the interval between the limiting sections 28 through the screw rod 293; the adjusting unit 29 can not only meet the requirement of quick disassembly of the rotation limiting piece 2 and the connecting piece 1, but also adjust the length of the rotation limiting piece 2, so that the length of the variable limiting guide rail 5 is changed, and the precision of the cut large-radius complex special-shaped template is improved.

Still further, after the overall shape adjustment of the plurality of connecting pieces 1 is completed, the shape of the variable spacing rail 5 is limited, however, when the sliding base plate 6 slides in the variable spacing rail 5, the shape of the variable spacing rail 5 is very easy to push to change, for this purpose, the shape of the variable spacing rail 5 needs to be limited, this embodiment proposes a further scheme, which comprises a limiting unit 3, the limiting unit 3 comprises a column-shaped cavity 31 opened in a column 13, a through groove 32 is relatively opened on the outer wall of the column 13, the through groove 32 is correspondingly matched with the arc-shaped limiting part 14, in addition, friction plates 33 are relatively fixed at two ends of the rotation limiting piece 2, when the rotation limiting piece 2 is inserted into the arc-shaped limiting part 14, the friction plates 33 enter the column-shaped cavity 31 through the through groove 32, the column-shaped cavity 31 is rotationally provided with a mounting shaft 311, the mounting shaft 311 is overlapped with the axis of the cylinder 13, the mounting shaft 311 is provided with two pressure driving part groups which are arranged up and down oppositely, each pressure driving part group also comprises two pressure driving parts which are arranged oppositely, each pressure driving part is composed of a spiral section 34 and a limit section 35, the limit section 35 is positioned on a plane perpendicular to the axis of the mounting shaft 311, the limit section 35 is fixed on one end of the spiral section 34 far away from the geometric center of the mounting shaft 311, the inner wall of the cylinder chamber 31 is provided with a connecting rod group which is arranged up and down oppositely, each connecting rod group comprises two connecting rods 36 which are arranged oppositely, each connecting rod 36 is arranged corresponding to the pressure driving part, a pressurizing part 37 is arranged on each connecting rod 36 in a sliding way, an extrusion spring 38 is connected between each pressurizing part 37 and each connecting rod 36, the compression spring 38 is in a compressed state, a square lug is fixed on the pressurizing part 37, and the square lug abuts against the corresponding limiting section 35; when the angle between a certain rotation limiting piece 2 and a cylinder 13 needs to be limited, the mounting shaft 311 is driven to rotate, at the moment, the limiting section 35 moves simultaneously and gradually leaves the square lug (the rotating direction is that the square lug is far away from the corresponding spiral section 34), when the limiting section 35 is completely separated from the square lug, under the elastic action of the extrusion spring 38, the pressurizing part 37 moves rapidly and is attached to the friction plate 33, and the friction plate 33 is limited by the upper pressurizing part 37 and the lower pressurizing part 37, so that the relative position between the rotation limiting piece 2 and the cylinder 13 is limited, and the shape of the variable limiting guide rail 5 is limited; when the rotation limiting member 2 needs to be restored to an adjustable state, the mounting shaft 311 is reversely rotated, so that the spiral section 34 contacts with the square bump and gradually presses the square bump to return, and the pressurizing portion 37 is driven to return.

In all the above embodiments, the rotation limiting member 2 provides a plurality of functions, one of which is that the rotation limiting member 2 can be used for installing the adjacent connecting members 1 and enabling the angle between the adjacent connecting members 1 to be adjustable, the other of which is that the rotation limiting member 2 can be used for fixing the relative position of the connecting members 1 after the adjustment is completed, stabilizing the state of the variable limiting guide 5, and the third of which is that the distance between the adjacent connecting members 1 can be adjusted, so that the length of the variable limiting guide 5 is the same as the length of the large-radius complex profiled template.

In a further embodiment, to drive the mounting shaft 311 to rotate, after each connector 1 is mounted, a certain mounting shaft 311 may be separately driven to rotate, however, a plurality of mounting shafts 311 may be synchronously driven to rotate simultaneously, the present embodiment only provides a solution that can be referred to, the mounting shaft 311 penetrates through the column-shaped chamber 31 and extends to the outside, and the rotating gear 4 is detachably mounted on the end of the mounting shaft 311 far away from the column-shaped chamber 31, because the mounting shaft 311 is located in the middle of the connector 1, each rotating gear 4 may be meshed with each other, so that by rotating one of the rotating gears 4, the plurality of rotating gears 4 may be driven to rotate simultaneously; in this way, it is not necessary to install all the connectors 1, and after a certain number of connectors 1 are installed, the plurality of connectors 1 of the section may be defined first, and it should be noted that, at this time, the plurality of rotary gears 4 of the section may be separated from the plurality of rotary gears 4 of the other sections, and only the rotary gears 4 at the intervals may be removed.
