The invention relates to the field of jacks, in particular to a jack provided with auxiliary supporting legs. The jack comprises a lifting mechanism, an auxiliary mechanism, an angle mechanism, a replacement mechanism, a pop-up mechanism and a rotating mechanism. Through arrangement of the lifting mechanism, a heavy object can be jacked up without occupying extra space; through arrangement of the auxiliary mechanism, lifting and automatic stretching of the lifting mechanism can be synchronized, so that the contact area between the jack and the ground is increased, and the use safety of the jack is improved; through arrangement of the angle mechanism, the included angle between the auxiliary mechanism and the lifting mechanism can be freely adjusted according to on-site use adjustment; through arrangement of the replacement mechanism, different contact parts can be freely replaced according to the shape of the jacked object, so that the jacked object is prevented from being damaged in the jacking process; through arrangement of the pop-up mechanism, the contact part is convenient to take; through arrangement of the rotating mechanism, a rotating part in the lifting mechanism can be rotated in a labor-saving mode, and the operation difficulty of the jack is reduced.

    本发明涉及千斤顶领域,具体的说是带有辅助支脚的千斤顶,包括升降机构、辅助机构、角度机构、替换机构、弹出机构和转动机构;通过升降机构的设置能够实现在不占用多余空间的情况下将重物顶起,通过辅助机构的设置能够同步升降机构的起降自动伸展,从而增大了千斤顶和地面的接触面积,提高了千斤顶的使用安全性,通过角度机构的设置能够根据现场使用调节所限而自由调节辅助机构和升降机构之间的夹角,通过替换机构的设置能够根据被顶起物的形状自由替换不同的接触部件,从而避免被顶起物在顶升过程中破损,通过弹出机构的设置从而便于拿取接触部件,通过转动机构的设置能够省力转动升降机构内部的转动部件,降低了千斤顶的操作难度。
