[0047] In a specific embodiment of the present invention, two groups of first sliding components are installed on the upper surface of the bottom plate 1. The first slider 203 is slidably connected to the surface of the first slide bar 202. Grease needs to be applied to the circumferential surface of the first slide bar 202 to facilitate the sliding of the first slider 203 on the surface of the first slide bar 202. When the grease content decreases, grease needs to be applied to the surface of the first slide bar 202. By installing an oil injection mechanism in the T-shaped card slot 204, when the first slider 203 is used, the oil injection mechanism automatically injects oil continuously onto the surface of the first slide bar 202. The oil injection main body 3 is connected to the T-shaped card slot 204 through the T-shaped card block 5. An oil pipe 4 is installed in the installation slot 301. Grease is stored in the oil storage chamber 401. The reaction of the reaction component increases the pressure on the upper side of the oil storage chamber 401. The extrusion block 402 is pushed by the extrusion to extrude the grease in the oil storage chamber 401 from the oil pipe 4. The grease is extruded onto the surface of the first slide bar 202 through the oil injection channel 303, the semi-circular groove 304, and the oil injection hole 305, continuously applying grease to the surface of the first slide bar 202 to facilitate the sliding of the first slider 203. The lower part of the circumferential surface of the installation slot 301 is provided with a thread matching the oil pipe 4. When the oil pipe 4 is installed in the installation slot 301, the oil pipe 4 is fixed by the threaded connection between the oil pipe 4 and the installation slot 301, facilitating its installation and disassembly.

[0048] Specifically, please refer to Figures 1 - 10 , an oil storage chamber 401 is provided in each oil pipe 4, and an extrusion block 402 is slidably connected in each oil storage chamber 401.

[0049] In this embodiment: The oil storage chamber 401 is used to store grease. The pressure generated during the operation of the reaction component pushes the extrusion block 402 to extrude the grease in the oil storage chamber 401.

[0050] Specifically, please refer to Figures 1 - 10 , each group of reaction components includes a reaction chamber 403, a delivery channel 404, a storage bag 405, air holes 406, magnesium particles, and hydrochloric acid solution. There are multiple air holes 406. The reaction chamber 403 is opened in the oil pipe 4. Multiple air holes 406 are opened in the bottom plate 1. The air holes 406 communicate the reaction chamber 403 and the oil storage chamber 401. The storage bag 405 is fixedly connected to the upper end of the oil pipe 4.

The magnesium particles are arranged in the reaction chamber 403, and the hydrochloric acid solution is arranged in the storage bag 405.

[0051] In this embodiment: By pressing the storage bag 405, the hydrochloric acid solution in the storage bag 405 is extruded and pressed into the reaction chamber 403 through the delivery channel 404. The hydrochloric acid solution reacts with the magnesium particles to release hydrogen gas. The gas enters the upper part of the oil storage chamber 401 through the air holes 406. The hydrogen gas squeezes the extrusion block 402, and the extrusion block 402 squeezes the grease in the oil storage chamber 401 to be continuously extruded.

[0053] In this embodiment: The film located in the conveying channel 404 is used to prevent the hydrochloric acid solution in the storage bag 405 from directly flowing into the reaction chamber 403. After the film in the conveying channel 404 is broken through by pressing the storage bag 405, the hydrochloric acid solution enters the reaction chamber 403. The film located at the lower part of the inner circumferential wall of the oil storage tank 401 is used to prevent the grease in the oil storage tank 401 from flowing out. When the oil pipe 4 is threadedly connected to the installation groove 301, the film is squeezed and broken by the conical block 302. At this time, the grease in the oil storage tank 401 is extruded through the oil injection channel 303.

[0058] For details, please refer to Figures 1 - 10 , a third electric push rod 8 is fixedly connected inside the second slider 7, and an installation plate 9 is fixedly connected to the extending end of the third electric push rod 8.

The magnesium pellets in the reaction chamber 403 gradually react with the hydrochloric acid solution to generate hydrogen. The pressure in the upper part of the oil storage chamber 401 increases, and the pressure squeezes the extrusion block 402, causing the extrusion block 402 to gradually push the grease in the oil storage chamber 401, so that the grease is extruded onto the surface of the first sliding rod 202 after passing through the oil injection channel 303, the semi-circular groove 304 and the oil injection hole 305. The T-shaped groove opened at the upper end of the second slider 7 is also used to install the oil injection mechanism, and the device in the mounting plate 9 is controlled to move in three-dimensional space respectively through the first electric push rod 207, the second electric push rod 702 and the third electric push rod 8; by using this device, the oil injection mechanism operates, and the oil injection mechanism continuously injects oil onto the surface of the sliding rod, so that the surface of the sliding rod is continuously lubricated, avoiding damage to the sliding rod caused by friction between the slider and the sliding rod after the grease on the surface of the sliding rod decreases, which is convenient for use.
