[0034] Specifically, Figures 1-2 As shown, the adjustment mechanism is connected with the tray 1 and the plurality of ejector pins 3 to adjust the height of the plurality of ejector pins 3 in the plurality of through holes 21. The adjustment mechanism comprises: a clamping column 41, a lifting seat 42 and a guide assembly. The top of the clamping column 41 is connected to the bottom of the tray 1, and a plurality of clamping positions 411 are provided on the clamping column 41; the top of the lifting seat 42 is connected to the bottom of the plurality of ejector pins 3, the lifting seat 42 is located at the bottom of the tray 1, and an adjustment hole 421 is provided on the lifting seat 42, and the lifting seat 42 is sleeved on the clamping column 41 through the adjustment hole 421, and a pair of clamping clips 422 are hinged on the adjustment hole 421, and a spring 423 is connected between the tops of the pair of clamping clips 422. The pair of clamping clips 422 use the elastic force of the spring 423 to allow the tops of the pair of clamping clips 422 to approach each other, so that the tops of the pair of clamping clips 422 are clamped with any of the clamping positions 411; the guide component connects the lifting seat 42 and the tray 1, and is used to guide the movement of the lifting seat 42 to ensure the stability of the movement of the lifting seat 42.

[0035] Further, if Figures 1-2 As shown, a control handle 424 is provided at the bottom of a pair of clamps 422, so that the control handles 424 at the bottom of the pair of clamps 422 are squeezed against each other to bring the control handles 424 closer to each other, thereby separating the tops of the pair of clamps 422 from each other, and disengaging the tops of the clamps 422 from the locking position 411, thereby realizing the lifting and lowering adjustment of the lifting seat 42.

[0036] Further, if Figures 1-2As shown, the guide assembly includes: four guide posts 431 and four guide sleeves 432. The four guide posts 431 are arranged at the bottom of the tray 1; the four guide sleeves 432 are respectively arranged at the four corners of the lifting seat 42, and the four guide sleeves 432 are respectively sleeved in the four guide posts 431.

[0040] Further, if Figures 1-2 As shown, the rivet length adaptation structure of the embodiment of the utility model further includes: a positioning column 6, which is arranged on the top of the positioning member 2 and is used to position the motor 7.

[0041] When in use, first adjust the height of the multiple ejector pins 3 as needed, and squeeze the bottom control handles 424 of a pair of clamping clips 422 to bring the control handles 424 closer to each other, so that the tops of the pair of clamping clips 422 are separated from each other, and the tops of the clamping clips 422 are separated from the locking position 411 (the spring 423 expands outward at this time), and then adjust the height of the lifting seat 42, and then release the bottom control handles 424 of the pair of clamping clips 422. At this time, the spring 423 retracts, and the tops of the pair of clamping clips 422 are close to each other and locked with the locking position 411 at the height.

[0042] As described above, in the rivet length adaptation structure according to the embodiment of the utility model, an adjustment structure is provided at the bottom of the plurality of ejector pins 3, so that the height of the ejector pins 3 can be adjusted to adapt to rivets of different lengths.
