Wherein, adjusting screw 5 is provided with two, and two adjusting screw 5 are 45 degrees settings of slope, and two adjusting screw 5's one end rotates with one of them in upper table body 1-1 and the lower table body 1-2 respectively and is connected, and two adjusting screw 5 respectively with the screw thread cooperation in the other in upper table body 1-1 and the lower table body 1-2.

Specifically, opposite ends of the two adjusting screws 5 are respectively connected to the upper platform body 1-1 and the lower platform body 1-2 in a rotating manner, thread grooves for being in threaded fit with the adjusting screws 5 are formed in the upper platform body 1-1 and the lower platform body 1-2, and outer ends of the adjusting screws 5 extend to the outside of the detection platform 1. In the operation process, the space between the upper table body 1-1 and the lower table body 1-2 can be directly adjusted by rotating the adjusting screw 5, so that the jig capable of rapidly detecting the damage strength of the pin can be suitable for pins with different thicknesses, and the application range of the jig is improved.

In this embodiment, the ballast bar 2 is provided with a support plate 6, the bottom of the support plate 6 is provided with a support rod 8 inserted from the top end of the lower stage body 1-2 and elastically supported by a spring 7, the upper stage body 1-1 is provided with a loading channel 9 for lifting and lowering the ballast bar 2, and the width of the channel is larger than that of the ballast bar 2.

When the width direction of the channel is parallel to the distance between the upper platform body 1-1 and the lower platform body 1-2, the displacement direction of the upper platform body 1-1 and the lower platform body 1-2 is regulated, so that the ballast rod 2 can be suitable for the upper platform body 1-1 and the lower platform body 1-2 when the distance is in different states.

Further, the opposite sides of the upper platform body 1-1 and the lower platform body 1-2 are respectively provided with an upper vertical section 1-3, a middle horizontal section 1-4 and a lower vertical section 1-5 which are distributed in sequence from top to bottom, the joints of the middle horizontal section 1-4, the upper vertical section 1-3 and the lower vertical section 1-5 are respectively provided with an arc shape, and the detection channel 3 is arranged on the middle horizontal section 1-4.

Specifically, in the above embodiment, the top end of the upper vertical section 1-3 and the bottom end of the lower vertical section 1-5 are all in an open structure, and the three parts of the upper vertical section 1-3, the middle horizontal section 1-4 and the lower vertical section 1-5 can integrally form a complete passage for the pin to pass through the jig capable of rapidly detecting the breaking strength of the pin. The pin can be placed horizontally from the top of the upper vertical section 1-3, the pin rolls downwards under the action of gravity in the upper vertical section 1-3, and when the pin rolls onto the middle horizontal section 1-4, the pin enters the detection channel 3 and is supported by the support 4-1. At this time, the portion of the pin located inside the support portion 4-1 is located below the ballast bar 2 and above the groove 4.

After loading the ballast bar 2 with pressure and detecting the pins, the undeformed pins can enter the lower vertical sections 1-5 from within the middle horizontal sections 1-4 and roll out automatically, whereas the deformed pins can be pulled out directly. Therefore, the distance between the upper table body 1-1 and the lower table body 1-2 can be adjusted to be smaller than the size of the pin after bending deformation, and whether the pin is bent and deformed or whether the degree of the pin after bending and deforming is within the process requirement range can be automatically judged.

In this way, an automatic feeding of one pin can be achieved during each lowering of the ballast bar 2.

Similarly, during the ascent of the ballast bar 2 after detecting a pin, the lower baffle 11 extends from the lower platform 1-2 and the upper baffle 10 is retracted into the lower platform 1-2, at this time, the lowermost one of the pins blocked by the upper baffle 10 automatically falls onto the lower baffle 11 to be supported, so that the ballast bar 2 is automatically fed next time it descends. Therefore, in the process of each ascending of the ballast rod 2, a pin can automatically enter between the upper baffle plate 10 and the lower baffle plate 11, so that the next detection is facilitated, and the cyclic automatic feeding process of the pin is realized.
