Pin puller with self-adaptive adjusting device

The invention relates to the technical field of pin pulling, in particular to a pin puller with a self-adaptive adjusting device, which comprises a connecting seat, a support cylinder slidably arranged in the connecting seat and a pin pulling mechanism arranged in the support cylinder, and the self-adaptive adjusting device is arranged between the connecting seat and the support cylinder. According to the pin puller, the pin pulling effect is improved, the application range is larger, the size of the pin puller in the length direction is reduced, damage to the pin puller is greatly reduced, and the situation that the machining face of the local side face of the pin shaft is damaged by a swinging hammer and the precision size of the pin shaft is affected is effectively avoided. 本发明涉及拔销的技术领域，尤其是一种具有自适应调节装置的拔销器，包括连接座、滑动设置在连接座内的支撑筒、以及支撑筒内设置的拔销机构，所述的连接座和支撑筒之间设置有自适应调节装置。本发明提高了拔销的效果，适应范围更大，减小了拔销器长度方向的尺寸，也大大降低了拔销器的损坏，有效的避免了销轴被甩锤破坏销轴局部侧面加工面以及影响了销轴的精度尺寸。
