[0024] In an embodiment of the present utility model, a threaded rod 2 is provided on a base 1. The threaded rod 2 can be fixed to the center of the base 1 by means of welding, threaded connection or other connection methods. Then, a nut seat 3 is arranged on the threaded rod 2, and operating handles 4 are respectively arranged on both sides of the nut seat 3. By acting on the operating handles 4, the nut seat 3 can be driven to rotate. There is a threaded connection between the nut seat 3 and the threaded rod 2. Therefore, when the nut seat 3 rotates, it can rise or fall in the threaded rod 2. A jacking part is sleeved on the upper part of the threaded rod 2. By adopting a sleeved connection method, the jacking part can not only freely rise and fall on the top of the threaded rod 2, but also different styles of jacking parts can be selected according to the specific structure of the object to be jacked. It only needs to sleeve the jacking part on the threaded rod 2. When the nut seat 3 rises, the top of the nut seat 3 acts on the bottom of the jacking part, so that the jacking part rises. When the nut seat 3 descends, the jacking part automatically descends under the action of its own weight. Through the above structural settings, when an object needs to be jacked, this device is placed under the object to be jacked, and then a person acts on the operating handle 4. The operating handle 4 drives the nut seat 3 to rotate. The nut seat 3 acts on the jacking part, and the jacking part acts on the object to be jacked, thereby realizing the jacking of the object to be jacked.
