[0026] The working principle of this utility model:

[0027] When in use, the motor 3 drives the threaded shaft 4 to rotate, and the linkage plate 5 moves downward through the relative threaded movement with the threaded shaft 4, and then the linkage plate 5 drives the base 7 to move downward through the two lifting rack columns 6. Since the base 7 is located on the ground and is subjected to the reaction force from the ground, the base 1 moves up in contrast, thereby achieving the purpose of adjusting the overall height. Before adjustment, it is necessary to pull the locking pin 82 laterally through the pull ring 83, and the locking pin 82 is separated from the lifting rack column 6, which can release the restriction on the lifting rack column 6. After the overall height is adjusted, the pull ring 83 can be released, and the locking pin 82 will be reset under the action of the spring 1 86 and engage with the lifting rack column 6. In this way, the force on the threaded shaft 4 can be reduced, and the stability after overall adjustment can be improved.

[0028] In addition, by pushing the push rod 97 laterally through the push block 98, the push rod 97 can give the inclined plane block 92 a downward thrust, and then the inclined plane block 92 squeezes the oil storage sponge 96 and releases the lubricating oil in the oil storage sponge 96. The lubricating oil flows to the threaded connection between the threaded shaft 4 and the linkage plate 5 under the guidance of the oil collecting plate 10, and then lubricates the thread, thereby ensuring that the machine tool can be lifted and lowered smoothly and is not prone to jamming.
