Description

Technical Field

[0001] The utility model relates to the technical field of jacks, in particular to a jack with stable support. Background Art

[0002] The advantages of a car jack are that it is light, small in size when folded, and easy to store, but its disadvantages are that the support may not be strong enough, and it is generally only suitable for family cars weighing just over 1 ton.

[0003] The larger the area of ​​the jack base, the larger the contact area with the ground, which helps to disperse the weight of the heavy object and reduce the pressure per unit area. In this way, the jack is less likely to shake or tilt during the lifting process, thereby ensuring the stability and safety of the support. However, the scissor-type jack used in the car is usually stored in a small box and placed in the trunk of the car. In order to keep the overall size of the jack small and easy to store and store, in actual design, the area of ​​the jack base is not designed to be large, and the problem of unstable support will occur during use. Therefore, it is necessary to design a jack with a larger bottom area that does not affect the box storage of the jack, so as to solve the above technical problems. Utility Model Content
