The invention relates to the field of trailer jacks, in particular to a trailer jack connecting seat which comprises a fixing plate, a rotating shaft rotatably mounted on the fixing plate, a torsion spring connected between the fixing plate and the rotating shaft, a positioning sleeve fixedly connected to the fixing plate and used for supporting the rotating shaft, and a limiting pin inserted into the rotating shaft and the positioning sleeve. The torsion spring is installed on the trailer jack connecting seat and can rotate along with the rotating shaft and the trailer jack, and in the process of releasing the trailer jack, the torsion spring converts gravitational potential energy of the trailer jack into elastic potential energy, so that the rotating speed of the trailer jack is slowed down, the impulse is reduced, and the safety risk of collision is avoided; in the process of retracting the trailer jack, the torsion spring converts the elastic potential energy into the gravitational potential energy of the trailer jack, the situation that a user does work by overcoming the gravity of the trailer jack is reduced, more labor is saved when the user retracts the trailer jack, and the experience is good.

    本发明涉及一种拖车千斤顶连接座,涉及拖车千斤顶的领域,其包括固定板、转动安装在固定板上的转轴、连接在固定板和转轴之间的扭转弹簧、固定连接在固定板上并用于对转轴进行支撑的定位套筒和插接在转轴和定位套筒上的限位销。本发明是在拖车千斤顶连接座上安装扭转弹簧,扭转弹簧能够随着转轴和拖车千斤顶转动,释放拖车千斤顶的过程中,扭转弹簧将拖车千斤顶的重力势能转化为弹性势能,使拖车千斤顶转动速度减缓、冲量减小,避免发生撞击的安全风险;收起拖车千斤顶的过程中,扭转弹簧将弹性势能转化为拖车千斤顶的重力势能,减少用户克服拖车千斤顶的重力做功,用户在收起拖车千斤顶时更省力、体验好。
