[0035] 1. The present invention provides a fixing seat, an arc plate and other structures, so that the user can install the plastic product on the carrying rod in advance, and then install the carrying rod in the snap-on structure formed by the ends of the arc plate and the fixing seat, thereby improving efficiency.

[0036] 2. During detection, the present invention drives each carrying rod to rotate by rotating the rotating frame. When the carrying rod rotates to the inner side of the fixing buckle, the carrying rod is blocked and limited by the fixing buckle, and the fixing seat is deflected from the guide column. At the same time, the second spring is stretched. At this time, due to the relative movement between the guide column and the fixing seat, the guide column can pull the arc plate inside the fixing seat through the traction rope, so that the carrying rod can be detached; then the arc plate, the fixing seat and other structures are reset based on the rebound force of the second spring and the elastic tube; the whole process achieves the purpose of transporting the carrying rod from the rotating frame to the fixing buckle only by rotating the rotating frame; the user can install the new carrying rod at the fixing seat to facilitate continuous detection, which greatly improves efficiency.

[0037] 3. The present invention provides an internal support assembly, which can make the slide slide on the outer wall of the carrying rod by screwing the threaded seat, and then under the transmission of the connecting rod, the first support seat moves away from the carrying rod, thereby achieving support for the inside of the plastic product.

[0038] 4. The present invention can conveniently adjust the position of the plastic product on the carrying rod by providing a movable second support seat. During installation, the plastic product can be fixed by first screwing the threaded seat and utilizing the internal support assembly. When the plastic product is adjusted to a suitable position, the second support seat slides relative to the first support seat when the position of the plastic product is adjusted. After the adjustment is completed, the plastic product is kept stationary, and the threaded seat is rotated in the opposite direction so that the second support seat is reset based on the rebound force of the first spring, and is locked again by screwing the threaded seat, thereby achieving the purpose of quickly adjusting the position of the plastic product.

[0039] 5. The present invention provides an extrusion mechanism that can work based on an electric telescopic cylinder to drive the carrying rod to move downward, thereby allowing the plastic product to pass between the two extrusion plates of the inverted "eight"-shaped structure, thereby achieving the purpose of extrusion.

[0040] 6. The present invention provides side bags and support bags. When a plastic product is squeezed, it can be squeezed from a circular shape to an elliptical shape because it is made of plastic. At this time, the two sides of the plastic product are squeezed laterally, which naturally causes the longitudinal expansion of the plastic product. At this time, the slide is compressed based on the squeezing of the plastic product, and then the gas is squeezed into the support bag through the connecting tube, and the support bag expands, thereby adapting to the longitudinal deformation of the plastic product, ensuring the firmness of the support, and improving the reliability.

[0041] 7. The present invention can further improve the fixing effect of the carrying rod by providing a protruding column. Since the end of the insertion hole is in a trumpet-shaped structure, the protruding column can be better guided to be inserted into the insertion hole, thereby improving reliability.

[0042] 8. The present invention provides a sealing airbag and an air circuit connector, wherein the sealing airbag can be inserted into the end of the plastic product, and the sealing airbag is expanded by inflation, thereby sealing the end of the plastic product. Based on the operation of the air pressure generating device, air is injected into the carrier rod through the air circuit connector, so that the gas enters the closed plastic product through the air injection hole, so as to facilitate the air injection test, and at the same time, it can detect whether the plastic product is damaged after extrusion.

The end of the fixed seat 17 away from the rotating frame 4 is in a C-shaped structure. The fixed seat 17 and the rotating frame 4 are connected by a second spring 26. Under the support of the second spring 26, the fixed seat 17 can maintain a parallel state with the guide column, but the width of the socket is greater than the width of the guide column. A certain angle of angular deflection can occur between the fixed seat 17 and the guide column. Multiple fixed seats 17 are arranged in a circular distribution about the rotation center of the rotating frame 4;

[0059] The arc plate 29, one end of which is connected to the guide column through a traction rope 27, a side bracket 28 is fixed to the side of the arc plate 29, and the side bracket 28 is connected to the fixed seat 17 through an elastic cylinder 20, and an arc-shaped slide groove is provided on the inner side of the C-shaped structure end of the fixed seat 17, and the arc plate 29 is slidably connected to the inner wall of the arc-shaped slide groove, and the ends of the arc plate 29 and the fixed seat 17 cooperate to form a buckle-like structure, and when the fixed seat 17 moves toward the end of the guide column away from the rotating frame 4, the arc plate 29 can be pulled into the fixed seat 17 based on the traction of the traction rope 27;

During the inspection, the rotating frame 4 is rotated to drive each carrying rod 2 to rotate. Since the fixing buckle 24 is located on the moving path when the carrying rod 2 follows the rotation of the rotating frame 4, when the carrying rod 2 rotates to the inside of the fixing buckle 24, as the rotating frame 4 continues to rotate, the carrying rod 2 is blocked and limited by the fixing buckle 24, and the fixing seat 17 will deflect from the guide column, and the second spring 26 will be stretched. At this time, due to the relative movement between the guide column and the fixing seat 17, the guide column can pull the arc plate 29 into the fixing seat 17 through the traction rope 27, so that the carrying rod 2 can be disengaged, and then the arc plate 29 and the fixing seat 17 and other structures are reset based on the rebound force of the second spring 26 and the elastic cylinder 20;

[0065] The whole process achieves the purpose of transporting the carrying rod 2 from the rotating frame 4 to the fixing buckle 24 only by rotating the rotating frame 4; the user can install the new carrying rod 2 on the fixing seat 17 to facilitate continuity detection, which greatly improves efficiency.

[0071] By setting up an internal support assembly, the slide 32 can slide on the outer wall of the carrying rod 2 by screwing the threaded seat 31, and then under the transmission of the connecting rod 33, the first support seat 21 moves away from the carrying rod 2, thereby supporting the inside of the plastic product 3.

[0072] To improve practicality; Figure 7 , Figure 8 As shown, a second support seat 40 is slidably connected to the first support seat 21, and the second support seat 40 is connected to the first support seat 21 through a first spring 39. A plurality of rollers 38 are arranged on a side of the first support seat 21 close to the second support seat 40, and the rollers 38 roll on a side of the second support seat 40 close to the first support seat 21, and an anti-slip pad 25 is arranged on an outer wall of a side of the second support seat 40 away from the first support seat 21;

After the adjustment is completed, the plastic product 3 is kept stationary, and the threaded seat 31 is rotated in the opposite direction, so that the second support seat 40 is reset based on the rebound force of the first spring 39, and is locked again by screwing the threaded seat 31, thereby achieving the purpose of quickly adjusting the position of the plastic product 3.

[0081] By providing the side bags 22 and the support bags 35, when the plastic product 3 is squeezed, it can be squeezed from a circular shape to an elliptical shape because it is made of plastic. At this time, the two sides of the plastic product 3 are squeezed laterally, which naturally causes the plastic product 3 to expand longitudinally. At this time, the slide 32 is compressed based on the squeezing of the plastic product 3, and then the gas is squeezed into the support bag 35 through the connecting tube 30, and the support bag 35 expands, thereby adapting to the longitudinal deformation of the plastic product 3, ensuring the firmness of the support, and improving the reliability.
