[0027] To better understand the purpose, structure, and function of the present utility model, the following further describes in detail a convenient-to-use jack of the present utility model with reference to the accompanying drawings.

[0028] Such as Figures 1-4As shown in the figure, a jack that is convenient to use according to the present utility model includes a hydraulic cylinder 1, a load-bearing plate 4, an L-shaped plate 5 and a bottom plate 3. The surface of the load-bearing plate 4 is fixedly connected to the L-shaped plate 5. The surface of the bottom plate 3 is fixedly connected to a scale plate 6. The surface of the L-shaped plate 5 is fixedly connected to a first scale plate 7. The surface of the scale plate 6 penetrates through the first scale plate 7. The surface of the scale plate 6 is slidably connected to a first baffle 28. The surface of the first baffle 28 is threadedly connected to a first hand-tightening screw 29. In this way, a scale plate 6 structure is provided on the surface of the jack, and a slidable first scale plate 7 and first baffle 28 structures are provided on the surface of the scale plate 6. The first baffle 28 can be adjusted to the required lifting height first and fixed by tightening the first hand-tightening screw 29. Then, when the L-shaped plate 5 is lifted, the lifting can be stopped when the first scale plate 7 fits the first baffle 28, reducing the operation of the hydraulic rod 2 to adjust the height for the second time, and making the use of the jack more convenient to a large extent. The surface of the scale plate 6 is fixedly connected to a limit plate 11. In this way, when adjusted to the highest position, it can be clearly observed by people, thus ending the lifting, and making the use of the jack more convenient to a large extent.

[0029] The top of the bottom plate 3 is fixedly connected to a spring 13. The other end of the spring 13 is fixedly connected to a connecting column 19. The surface of the connecting column 19 is fixedly connected to the load-bearing plate 4. The surface of the connecting column 19 is fixedly connected to a third connecting plate 18. The surface of the third connecting plate 18 is threadedly connected to a second connecting plate 17. The surface of the second connecting plate 17 is fixedly connected to a second protective housing 15. The bottom of the bottom plate 3 is threadedly connected to a first connecting plate 16. The top of the first connecting plate 16 is fixedly connected to a first protective housing 14. The second protective housing 15 is slidably connected inside the first protective housing 14. In this way, by providing a detachable first protective housing and second protective housing structure on the surface of the spring 13, when the spring 13 breaks, the spring 13 can be blocked from flying out to a large extent, and the safety protection performance of the device is improved to a large extent.

[0030] The surface of the load-bearing plate 4 is fixedly connected to a second scale plate 8. The surface of the scale plate 6 penetrates through the second scale plate 8. The surface of the scale plate 6 is slidably connected to a second baffle 9. The surface of the second baffle 9 is threadedly connected to a second hand-tightening screw 10. In this way, when the load-bearing plate 4 needs to be used, the second baffle 9 can be adjusted to the required lifting height first, and then fixed by tightening the second hand-tightening screw 10. Then, when the load-bearing plate 4 is lifted, the lifting can be stopped when the second scale plate 8 fits the second baffle 9, reducing the operation of the hydraulic rod 2 to adjust the height for the second time, and making the use of the jack more convenient to a large extent.

[0031] The surface of the bottom plate 3 is provided with a first groove 12. At the top of the bottom plate 3, there is a hydraulic cylinder 1. At the top of the hydraulic cylinder 1, there is a hydraulic rod 2. The top of the hydraulic rod 2 is fixedly connected to a bearing plate 4. A second groove 27 is opened at the top of the bearing plate 4. In this way, the roughness of the contact surface is increased by the chute structure provided at the top of the bearing plate 4, which can largely prevent the bearing plate 4 from sliding with the loaded object, and greatly improves the stability of the device.

[0032] The top of the bottom plate 3 is fixedly connected to a pump body 20. At the top of the pump body 20, there is a plug column 21. The top of the plug column 21 is connected to a three-way connecting pipe 24 through a rotating shaft. The surface of the three-way connecting pipe 24 is connected to a shaft plate 25 through a rotating shaft. The shaft plate 25 is connected to a clamping plate 26 through a rotating shaft. The bottom of the clamping plate 26 is fixedly connected to the bottom plate 3. In this way, by providing the plug column 21 and the pump body 20, the hydraulic rod 2 is lifted by the up and down movement of the plug column 21, which greatly improves the practicability of the device.

[0033] A handle 22 is inserted into the inner side of the three-way connecting pipe 24. A rubber sleeve 23 is fixedly connected to the surface of the handle 22. In this way, by providing the rubber sleeve 23 at the end of the handle 22, the friction coefficient is increased, which greatly makes the handle 22 more convenient to rotate.

[0034] The working principle of this easy-to-use jack: Before using this jack, choose whether to use the L-shaped plate 5 or the bearing plate 4 according to the space at the bottom of the object to be loaded. When choosing the bearing plate 4, first adjust the second baffle 9 to the required lifting height, and then fix it by tightening the second hand-tightening screw 10. Then, by repeatedly pressing the handle 22 downward and pulling the handle 22 upward, the plug column 21 moves up and down, so as to provide the lifting force for the hydraulic rod 2 through the pump body 20, making the bearing plate 4 rise, which greatly makes the jack more convenient to use. When the second scale plate 8 fits the second baffle 9, the lifting can be stopped, reducing the operation of adjusting the height of the hydraulic rod 2 again, which greatly makes the jack more convenient to use. When the load is close to the ground, use the L-shaped plate 5. First adjust the first baffle 28 to the required lifting height, and fix it by tightening the first hand-tightening screw 29. Then lift the L-shaped plate 5. When the first scale plate 7 fits the first baffle 28, the lifting can be stopped, reducing the operation of adjusting the height of the hydraulic rod 2 again, which greatly makes the jack more convenient to use. A limit plate 11 is fixedly connected to the surface of the scale plate 6. In this way, when adjusted to the highest position, it can be clearly observed by people, so as to end the lifting, which greatly makes the jack more convenient to use. And a detachable first protective shell and second protective shell structure are provided on the surface of the spring 13. When the spring 13 breaks, it can largely prevent the spring 13 from flying out, which greatly improves the safety protection performance of the device.
