[0027] As Figure 1 And Figure 2 As shown in one of preferred embodiments, conveying assembly 2 includes motor two 201 installed on the outer wall of bottom plate 1, the end of motor two 201 output shaft is fixedly equipped with screw rod 202, recess 203 is opened on the top of bottom plate 1, the inner wall of recess 203 is rotatably connected with one end of screw rod 202 away from motor two 201, the outer wall of screw rod 202 is threadedly connected with fixed frame 204, the outer wall of fixed frame 204 is fixedly connected with fixed shaft 301, screw rod 202 is driven to rotate by motor two 201, fixed frame 204 is moved horizontally by the rotation of screw rod 202, in turn, support component 3 is moved to the position of support platform 4, which is conducive to improving the convenience of inner tube replacement, and improving the accuracy of replacement.

[0028] As Figure 1 As shown in one of preferred embodiments, square groove 101 is opened on the top of bottom plate 1, and lifting ring 102 is rotatably connected with the inner wall of square groove 101, by setting square groove 101 and lifting ring 102, it is conducive to changing the position of the device through lifting ring 102, thereby improving the convenience of moving the device.

[0029] As Figure 1 And Figure 2As shown, in one preferred embodiment, a fixing groove 103 is provided at the bottom of the base plate 1, and an anti-slip pad 104 is fixedly installed on the inner wall of the fixing groove 103. By setting the fixing groove 103 and the anti-slip pad 104, it is beneficial to improve the friction between the device and the contact surface, thereby improving the stability of the device during use.

[0030] like Figure 2 and Figure 3 As shown, in one preferred embodiment, a connecting groove 309 is provided on the side of the support ring 308 away from the connecting rod 307. A protective pad 310 is fixedly fitted on the inner wall of the connecting groove 309. By setting the connecting groove 309 and the protective pad 310, it is beneficial to improve the friction between the support ring 308 and the inner wall of the inner tube, while reducing the wear on the inner wall of the inner tube and improving the service life of the inner tube.

[0031] In one preferred embodiment, the base of the support platform 4 is connected to the base plate 1 via a pin-slot pair. Considering that the range of pipe specifications used in this utility model is relatively wide, the support platform 4 can be adapted to manufacture more diameter specifications of support arc surface styles to meet assembly needs. Since the support platform 4 is not a support structure that needs to withstand severe loads, the pin-slot pair method makes assembly easier for construction workers and also makes it easier to replace.

[0032] In operation, the technical solution provided by this utility model uses a motor 303 to drive a bidirectional threaded rod 304 to rotate, which in turn drives two sets of moving rings 305 to move in opposite directions, thereby pushing the connecting rod 307 to rotate. The movement of the moving rings 305 drives the support rings 308 to move laterally, allowing the structure to gradually adapt to the inner wall of the inner tube and finally achieve positioning. Since the structure uses four sets of support rings 308, it can accommodate the length of the guide screws 202 of more specifications, making the effective stroke range of the overall positioning tool larger. Therefore, the support component 3 in this solution can be inserted more completely into inner tubes of more specifications.

[0033] When the above-mentioned support assembly 3 enters the required position of the inner tube, the four sets of support rings 308 support and limit the four-point positioning of the inner tube, the inner tube will be more evenly flattened after being inserted into the sleeve, and by changing the curvature of the support ring 308, it will be appropriately reduced, under the condition that the specifications of the cooperating structures such as the lead screw 202 allow, the device can be adapted to more different specifications of the inner tube and the outer sleeve, four-point positioning is more helpful to the structural stability of the support assembly 3 compared with two-point or three-point positioning, especially it can provide the inner tube with more stress points, which is conducive to the good cooperation of the inner tube with the sleeve; and by rotating the lead screw 202 to drive the fixed frame 204 to move horizontally, and then drive the support assembly 3 to move to the position of the supporting table 4, the inner tube can be driven to displace relative to the sleeve, which can expand the stroke range of the above-mentioned tool structure to a certain extent, and facilitate accurate adjustment of the assembly effect of the pipe.

[0034] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
