The transverse moving equipment structure 5 includes two independent PIN pressing mechanisms 506 and two PIN receiving mechanisms 507. Each PIN pressing mechanism 506 has a PIN pressing mechanism fixedly installed on its top. N cylinder 5061, each PIN pressing mechanism 506 has a moving cylinder 5062 at its bottom. Each PIN pressing mechanism 506 drives a pressing needle 5063 through the PIN pressing cylinder 5061. The extension cylinder drives the PIN pressing mechanism and the PIN receiving mechanism to move up and down. The two PIN receiving mechanisms 507 of the transverse moving device structure 5 are each provided with a PIN receiving left and right slider 5071. The sleeve shell of each PIN receiving left and right slider 5071 is provided with a spring mounting groove 5072.
