Embodiment
To make the technical means, creative features, achievable purpose and effectiveness that the utility model is realized easy to understand, below
With reference to embodiment, the utility model is expanded on further.
As shown in Figs. 1-2, a kind of high-safety hydraulic jack, including bottom plate 1 and pallet 8, the bottom of bottom plate 1 are equipped with four ten thousand
To wheel 2, one end of bottom plate 1 is equipped with operation handle 13, and the side inner wall of bottom plate 1 is fixedly connected with one end of hydraulic cylinder 3, hydraulic cylinder
3 other end is fixedly connected by hydraulic stem with one end of support plate 4, and the top of support plate 4 is equipped with spring fixed column 6, spring
Fixed column 6 is fixedly connected by resetting spring 5 with one end of bottom plate 1, the both sides of support plate 4 and the bottom both sides of lifting arm 7
It is fixedly connected, the both sides of bottom plate 1 are equipped with shaft 10, and the side of one end of two shafts 10 respectively with two supporting blocks 14 is fixed
Connection, one of shaft 10 are equipped with pull rod 11, and the top of lifting arm 7 is fixed with pallet 8.
Wherein, the bottom sides of supporting block 14 are equipped with several fixture blocks 15, and the bottom sides of lifting arm 7 are equipped with and fixture block
