The invention provides a firm and labor-saving limiting pull pin, and relates to the technical field of table trolleys, the firm and labor-saving limiting pull pin comprises mounting plates, a first support arm and a second support arm, a left mounting plate and a right mounting plate are arranged, and a first screw rod is arranged above one side of each mounting plate; the first support arm and the second support arm are rotationally mounted with the two groups of mounting plates through first screw rods respectively, and a pressing plate is connected between the first support arm and the second support arm; when the first support arm and the second support arm are turned over and closed, only a pulling block needs to be loosened, a round steel rod is driven to reset under the action of an elastic assembly, a limiting rod on the pulling block penetrates through the mounting plate at the right end, and therefore the limiting rod extends into a positioning hole in the second support arm, and the purpose of fixing and fastening is achieved; during loosening, only the pulling block is pulled, the limiting rod can be pulled out of the positioning hole, the fixation can be released, therefore, the operation time can be saved to a greater extent, and the firm and labor-saving limiting pull pin is labor-saving, convenient and not easy to damage when being used.

    本发明提供了一种牢固省力的限位拉销,涉及物流台车技术领域,包括安装板、第一支臂和第二支臂,所述安装板设有左右两组,且两组所述安装板上一侧的上方均设有第一螺杆,所述第一支臂和第二支臂均通过第一螺杆分别与两组所述安装板转动安装,所述第一支臂和第二支臂之间连接有压板;本发明在第一支臂、第二支臂翻转闭合的时候,只需松开拉动块,利用弹性组件的作用带动圆钢杆复位,使得拉动块上的限位杆贯穿过右端的安装板,从而延伸至第二支臂上的定位孔内,以此完成固定紧固的目的,松开时,只需拔动拉动块,使得限位杆从定位孔中拔出即可解除固定,能更大限度的节省操作时间,用起来省力,便捷不易损坏。
