Description

Technical Field

[0001] The utility model belongs to the technical field of jacks, and in particular relates to a jack with a convenient replacement of a plug. Background Art

[0002] Jacks are divided into mechanical jacks and hydraulic jacks, and their principles are different. In principle, the most basic principle of hydraulic transmission is Pascal's law, that is, the pressure of the liquid is consistent everywhere.

[0003] The jacks that are easy to replace the head on the market have the following problems when used:

[0004] 1. When using traditional jacks that are easy to replace the top head, the jack's handle is often pried by the lifting handle, making the handle structure easily damaged and deformed after long-term use. When replacing this structure, the rivets need to be pried, which makes the replacement time-consuming and labor-intensive for the workers.

[0005] 2. When most jacks with easily replaceable top heads are used, the base is placed on the ground for a long time and is subject to wear and extrusion, which makes it easy to be damaged or deformed, affecting the workers' subsequent use of the jack to support heavy objects.
