The invention discloses a jack, and belongs to the technical field of rail traffic. The jack comprises a base, an oil tank, a hydraulic cylinder body and a jack support, wherein the oil tank and the hydraulic cylinder body are both fixed on the base; the oil tank is mounted at the front end of the hydraulic cylinder body; and the support is mounted at the lower end of the base. The jack has the following advantages: when the device is not provided with the support, the device can serve as a rail tie respacer; when the device is provided with the support, the device can serve as the jack; the device can simply and accurately work as the jack for a rail; and the device can also serve as the jack, so that the error is reduced, the operation is simple, and the working strength is reduced.
