[0032] Firstly, the handle 1 is the force application part of the operation, the drive assembly 3 is located inside the fixed cylinder 2, when the staff manually rotates the drive assembly 3, since the plurality of clamping mechanisms 4 are located at one end of the drive assembly 3 and are slidingly installed on the fixed cylinder 2, the rotation of the drive assembly 3 will push the plurality of clamping mechanisms 4 to move, so that the plurality of clamping mechanisms 4 are simultaneously away from each other along the radial direction of the fixed cylinder 2. In this process, the elastic potential energy is gradually stored in the clamping mechanism 4, and the storage of the elastic potential energy provides a certain pre-tightening force basis for the subsequent inner diameter measurement, which can ensure that there is stable contact and force between the clamping mechanism 4 and the plastic pipe 5 during the measurement process, then, when the plastic pipe 5 is placed at the end of the plurality of clamping mechanisms 4 close to each other and located at the central axis position of the fixed cylinder 2, the staff releases the drive assembly 3, the elastic potential energy in the plurality of clamping mechanisms 4 is released, at this time, the plurality of clamping mechanisms 4 will stably contact the outer wall of the plastic pipe 5, ensuring that the relative position between the device and the plastic pipe 5 is stable during the subsequent measurement process, and the staff presses the switch 8 on the handle 1. This operation will simultaneously start the two moving assemblies 6 symmetrically arranged at one end of the fixed cylinder 2 close to the plastic pipe 5, so that they are away from each other in a certain direction until they are close to the inner diameter of the plastic pipe 5. At this time, since the two moving assemblies 6 are provided with a scale 7, by observing the scale value on the scale 7 corresponding to the position of the moving assembly 6, the farthest distance between the two moving assemblies 6 can be accurately obtained, and this distance data is equivalent to the inner diameter size of the measured plastic pipe 5, so that the precise measurement of the inner diameter of the plastic pipe 5 of different sizes is realized.

[0033] In one embodiment, for the above-mentioned fixed cylinder 2, a plurality of support rods 201 are fixedly installed inside the fixed cylinder 2, and the drive assembly 3 comprises a drive block 301, one end of the drive block 301 is fixedly installed with a drive ring 302, and the drive ring 302 is slidingly installed on the plurality of support rods 201.

[0034] One end of the drive ring 302 is fixedly installed with a plurality of connecting rods 303, and one end of the plurality of connecting rods 303 is rotatably installed with a roller 304.

[0035] The clamping mechanism 4 comprises an arc inclined block 401, the roller 304 is located on one side of the arc inclined block 401, one end of the arc inclined block 401 is fixedly installed with a sliding rod 402, and the sliding rod 402 is slidingly installed on the fixed cylinder 2.

[0036] The sliding rod 402 penetrates through the fixed cylinder 2 and extends to the outside, one end of the sliding rod 402 is fixedly installed with an L-shaped rod 403, a tension spring 404 is sleeved on the circumferential surface of the sliding rod 402, one end of the tension spring 404 is fixedly installed on the fixed cylinder 2, and the other end is fixedly installed on the L-shaped rod 403.

[0038] A plurality of support rods 201 in the fixed cylinder 2 play a supporting and guiding role, the driving circular ring 302 at one end of the driving block 301 is slidably installed on the support rods 201, when the staff manually rotates the driving block 301, the driving block 301 will drive the fixedly installed driving circular ring 302 to rotate, the driving circular ring 302 will drive a plurality of connecting rods 303 at one end to rotate, and then a plurality of connecting rods 303 will respectively drive the rotatably installed rollers 304 to rotate, since the rollers 304 are located on one side of the arc-shaped block 401, when the driving circular ring 302 slides along the support rods 201, the rollers 304 are driven to move through the connecting rods 303. Since the arc-shaped block 401 has a special shape (inclined arc shape), the movement of the rollers 304 on the arc-shaped block 401 will push the arc-shaped block 401 to move outward along the radial direction of the fixed cylinder 2, the sliding rod 402 at one end of the arc-shaped block 401 is slidably installed on the fixed cylinder 2, and the sliding rod 402 extends to the outside through the fixed cylinder 2.

[0041] When the staff presses the switch 8 on the handle 1, the two telescopic rods 601 on the fixed cylinder 2 receive the starting signal, and the output shaft 602 at the output end starts to expand outward. Since the two telescopic rods 601 are symmetrically installed on the fixed cylinder 2, and the orientations of the two output shafts 602 are opposite, they will move in opposite directions at the same time, and the arc-shaped measuring plate 603 fixedly installed at the other end of the output shaft 602 will move close to the inner diameter of the plastic pipe 5 along with the movement of the output shaft 602, wherein the arc-shaped measuring plate 603 fixedly installed at one end of the scale 7 will drive the scale 7 to move, and the other arc-shaped measuring plate 603 will slide on the outer surface of the scale 7, and the distance between the two arc-shaped measuring plates 603 will gradually increase, until both arc-shaped measuring plates 603 contact the inner diameter of the plastic pipe 5, then the value on the scale 7 on the opposite face of the arc-shaped measuring plate 603 slidingly installed with the scale 7 from the other arc-shaped measuring plate 603 can be observed, that is, the distance of the inner diameter size of the plastic pipe 5 can be measured.
