Figure 1 is a perspective view of the model in a preferred embodiment; Figure 2 is an exploded view of the model in a preferred embodiment; Figure 3 is a partial enlarged view of the model in a preferred embodiment; Figure 4 This is a sectional view of the new model in a preferred embodiment adjusted to the highest level of the ejector pin; Figure 5 is a partial enlarged view of the new model in a preferred embodiment; Figure 6 is a view of the new model in a preferred embodiment Sectional view of the ejector pin adjusted to the lowest.

Please refer to Figures 1 to 4, the present invention is an eccentric adjusting device for ejector pins, which mainly has a rocker arm 10, an eccentric shaft 20 and a linkage block 30, wherein: the rocker arm 10 has two opposite ends 11, 12, one end 11 is connected to a power source 40, so that the rocker arm 10 can be driven by the power source 40, and swing around the power source 40, the The other end 12 of the rocker arm 10 has an adjustment groove 13 and an adjustment hole 14 that penetrates from the side 16 of the rocker arm 10 to the adjustment groove 13.

The eccentric shaft 20 has a first section 21 and a second section 22 eccentrically connected to the first section 21. The eccentric shaft 20 passes through the adjusting hole 14 and extends into the adjusting groove 13, so that the second section 22 is located in the adjusting groove 13; in this embodiment, the first section 21 has a first axis 211, and the second section 22 has a second axis 221, the end surface of the first section 21 is connected to the The end surfaces of the two sections 22, and the second axis 221 deviates from the first axis 211, so that the first axis 211 and the second axis 221 are not connected.

The linkage block 30 is arranged in the adjusting groove 13 and connected to the second section 22 of the eccentric shaft 20, and the linkage block 30 is provided for connecting the ejector pin 50.

In this embodiment, the adjusting groove 13 is recessed from one end surface of the rocker arm 10, so that the rocker arm 10 defines two convex portions 15 on both sides of the adjusting groove 13, and the adjusting hole 14 penetrates There are two convex portions 15 connected to the adjusting groove 13, and the number of the first section 21 of the eccentric shaft 20 is two, and the second section 22 is connected between the two first sections 21, so that the The two sections 22 are clamped between the two first sections 21, one of the first sections 21 is pivoted in the adjustment hole 14 of one of the protrusions 15, and the other first section 21 is pivoted in The other convex portion 15 is inside the adjusting hole 14.

Secondly, the side 16 of the rocker arm 10 is provided with a plurality of scales 17 and a plurality of scale holes 18 corresponding to each of the scales 17, and also has a positioning piece 61 and a plurality of positioning bolts 62, and the positioning piece 61 passes through A plurality of positioning holes 611 are provided.
