[0002] Spring plug products usually need to be inserted into tubular objects and used in conjunction with the tubular objects. In order to fully understand the quality of spring plug products, it is usually necessary to conduct multiple tests on them, including pull-out force testing.

When the spring plug product and the pulling member 20 are both plugged into the through hole 101, the pulling piece 22 is plugged into the spring plug product and the pressure assembly 21 is maintained at one end of the spring plug product away from the through opening 102.

When the spring plug product and the drawing member 20 are both inserted into the through hole 101, the cushioning piece 212 is located between the spring plug product and the pressure piece 211. When the drawing piece 22 and the tooling body 10 are subjected to any pulling force so that the spring plug product is subjected to a pulling force in a direction of moving out of the through hole 101 toward the through opening 102 relative to the tooling body 10, the drawing piece 22 squeezes the cushioning piece 212 through the pressure piece 211 so that the cushioning piece 212 applies a pulling force to the spring plug product.

The docking member 121 is installed on the main member 11 in a manner that the clamping part 1211 is inserted into the slot 1101 and the mating part 112 is retained in the channel 121101. In this way, the main member 11 and the docking member 121 are locked and connected as a whole in the axial direction of the through hole 101, and the main member 11 and the docking member 121 can be separated by any movement of the main member 11 and the docking member 121 so that the mating part 112 moves out of the channel 121101 and the clamping part 121 moves out of the slot 1101, and the design is simple, and the disassembly and assembly are convenient, and no other spare parts need to be introduced.

[0032] refer to Figures 1 to 3 Preferably, two of the card slots 1101 are provided, and the two card slots 1101 are located on both sides of the mating portion 112. The docking member 121 moves close to the mating portion 112 in a manner that one end of the clamping channel 121101 is aligned with the mating portion 112 until the mating portion 112 is clamped in the clamping channel 121101, and at this time, the two clamping portions 1211 move into the two card slots 1101 respectively.

[0033] refer to Figure 4In one embodiment, the card slot 1101 is provided with one and is in a ring shape, and the card slot 1101 is located at the outer peripheral side of the mating portion 112. The docking member 121 moves close to the mating portion 112 in a manner that one end of the clamping channel 121101 is located at any position in the radial direction of the mating portion 112 and is aligned with the mating portion 112 until the mating portion 112 is clamped in the clamping channel 121101, and at this time, the two clamping portions 1211 move into the card slot 1101 at the same time.

[0034] refer to Figure 3 Preferably, the docking member 121 has a socket 12101, and the connecting member 122 includes a butt joint 1221 and a rod 1222. The butt joint 1221 is formed by extending one end of the rod 1222, and the size of the rod 1222 matches the size of the socket 12101. When the docking member 121 is assembled to the main body 11, the socket 12101 is located at an end of the docking member 121 away from the main body 11, and the connecting member 122 is installed to the docking member 121 in such a manner that the butt joint 1221 abuts against the end surface of the socket 12101 close to the main body 11 and the rod 122 passes through the socket 12101. In this way, the connecting member 122 and the docking member 121 can be separated by pulling out the connecting member 122 in the direction in which the docking member 121 extends toward the main body 11, and the overall disassembly and assembly are convenient.

[0035] Preferably, the docking member 121 further forms a clamping space 12102, the clamping channel 121101 and the insertion hole 12101 are arranged opposite to each other and are both connected to the clamping space 12102, and the size of the clamping space 12102 is adapted to the size of the clamped portion 113. When the main body 11 and the connecting member 122 are assembled with the docking member 121, the clamped portion 113 and the abutting head 1221 are both placed in the clamping space 12102. In this way, when the connecting member 122, the rod 1222 and the pulling member 22 are subjected to any tensile force, the spring plug product can be uniformly stressed relative to the main body 11, so as to achieve higher detection accuracy.

[0036] Preferably, a cross-sectional dimension of the abutment joint 1221 in a radial direction of the rod portion 1222 is larger than a radial cross-sectional dimension of the insertion hole 12101 .

[0037] It is worth mentioning that the tooling for pulling force detection is suitable for the spring plug products with different apertures. When installing the spring plug products with different apertures, it is sufficient to replace the main body 11 with the matching size of the through hole 101 and the cushioning member 212 with the corresponding size, which greatly saves the detection cost.

[0038] It is worth mentioning that the pulling member 20 can be inserted into the through hole 101 at a port of the through hole 101 away from the through opening 102. When the main body 11, the connecting assembly 12 and the pulling member 20 are separated, the spring plug product is inserted into the through hole 101 from the through opening 102, and the pulling member 20 can be inserted into the through hole 101 from a port of the through hole 101 away from the through opening 102, and the pulling member 22 penetrates the spring plug product and the pressure assembly 21 abuts against the side of the spring plug product away from the through opening 102.
