All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 As shown, a screw jack that is convenient for maintenance includes a screw jack body 1, and further includes: a housing 2 disposed on the surface of the screw jack body 1. Connecting shells 3 are fixedly connected to the front side and the rear side of the screw jack body 1. The connecting shell 3 is fixed to one side of the screw jack body 1 to facilitate the installation of the installation component 6. Connecting plates 4 are fixedly connected to the front and rear sides of the housing 2. A first clamping block 5 is fixedly connected to the bottom of the connecting plate 4. The cooperation of the connecting plate 4 and the first clamping block 5 facilitates disassembly and assembly. A second spring 11 is fixedly connected to the bottom of the inner cavity of the connecting shell 3. The cooperation of the second spring 11 and the movable plate 12 can assist in ejecting the first clamping block 5. The top of the second spring 11 is fixedly connected to the movable plate 12. The top of the movable plate 12 is in movable contact with the first clamping block 5. An installation component 6 for disassembling and assembling the housing 2 is provided inside the connecting shell 3. The installation component 6 includes a first spring 601.

[0022] Clamping plates 7 are fixedly connected to both sides of the front and rear sides of the housing 2. When the clamping plates 7 descend, they will first contact the sphere 10. Since the material of the sphere 10 is rubber, the clamping plates 7 can be pressed firmly to be clamped on the surface of the insertion rod 9. The sphere 10 can limit the clamping plates 7. Fixing plates 8 are fixedly connected to both sides of the front and rear sides of the screw jack body 1. An insertion rod 9 for limiting the clamping plates 7 is fixedly connected to the top of the fixing plate 8. A sphere 10 is provided at the top of the insertion rod 9. The material of the sphere 10 is rubber.

[0023] The first spring 601 is fixed to the inner wall of the connecting shell 3, one side of the first spring 601 is fixedly connected to the plug plate 602, the front side of the plug plate 602 is fixedly connected to the push rod 603, the front side of the push rod 603 penetrates to the outside of the connecting shell 3 and is fixedly connected to the push plate 604, and both sides of one side of the plug plate 602 are fixedly connected to the sliding sleeve 605, and the push rod 603 is driven to move by pressing the push plate 604, and when the push rod 603 moves, the plug plate 602 is driven to move, and the first spring 601 is squeezed at the same time, and then The plug plate 602 will be separated from the surface of the first block 5, and a slide rod 606 is arranged inside the sliding sleeve 605. Both ends of the slide rod 606 are fixedly connected to the inner wall of the connecting shell 3. The sliding connection between the sliding sleeve 605 and the slide rod 606 can improve the stability of the plug plate 602 when moving. The surface of the push plate 604 is provided with a protective shell 607 for protecting the push plate 604. The push plate 604 can be protected by the protective shell 607.
