Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0027] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0029] Example 1:

[0030] The main structure of this embodiment is as follows: Figures 1-3As shown, it includes a support platform 1, support legs 2 and an alignment component. The lower end face of the support platform 1 is connected to multiple symmetrically arranged support legs 2. The alignment component is connected to the support platform 1. The alignment component includes a fixed component and a measuring component. The fixed component is connected to the support platform 1. When the fixed component is in use, the rotating end of the fixed component rotates to drive multiple moving ends to move synchronously and self-centeringly and contact the inner diameter of the bent pipe. The measuring component is arranged parallel to the fixed component, and the measuring component is connected to the support platform 1. When the fixed component is in use, the fixed component moves horizontally along the support platform 1 and contacts one end of the bent pipe to measure its angle.

[0031] The specific implementation process is as follows: the bent pipe is placed on the support platform 1, and then the staff starts the driving device 4. After the driving device 4 is started, the output shaft connected to its output end rotates and drives the rotating disk 5 to rotate synchronously. When the rotating disk 5 rotates, the moving groove 6 opened thereon will move synchronously. When the moving groove 6 moves, the position change of its arc structure relative to the clamping groove 8 and the through groove 11 will push the clamping rod 7 to move in the length direction of the clamping groove 8. The clamping rod 7 moves and gradually contacts the inner wall of the bent pipe to limit its movement, and it can be observed by observing the scale on the scale 13. Measure the diameter of the current elbow. At this time, pull the measuring ruler 17 to drive the sliding block 16 to move in the sliding groove 15 along the central axis of the sliding rod 14. The measuring ruler 17 moves and gradually contacts the end of the elbow away from the support platform 1. If the height of the elbow is too high, the rotating plate 20 can be rotated to splice it with the fixed plate 19 to form a longer measuring tool. The measuring ruler 17 is placed close to the elbow to measure its verticality. At the same time, the measuring ruler 17 can also be rotated to measure elbows with special bending angles, such as 45-degree elbows or other angles to see whether the elbow angle meets the requirements.
