[0023] A control component 31 and a telescopic cylinder 32 are installed inside the inner connecting seat 1, one end of the telescopic cylinder 32 is connected to one end of a rack 33, the upper side of the rack 33 is meshed with the outer side of an adjusting gear 34, and internal threaded adjusting columns 35 are symmetrically connected on both sides of the adjusting gear 34, and the internal threaded adjusting columns 35 are rotatably connected to the inner connecting seat 1 on the side away from the adjusting gear 34, and the four internal threaded adjusting columns 35 are respectively threadedly connected to the outer side of a plug-in rod 36, and the plug-in rod 36 is arranged in a "U" shape, and the size of the side of the plug-in rod 36 away from the internal threaded adjusting column 35 matches the size of the plug-in slot 22, and the threads on the outer sides of the two plug-in rods 36 are arranged oppositely.

[0024] In the specific implementation, in order to facilitate the stable placement and maintenance of the feed machine base and prevent the feed machine base from moving on the work surface, the mounting seat at the bottom of the feed machine base is divided into an inner connecting seat 1 and an outer mounting seat 2. The outer mounting seat 2 is first installed with the work surface through the locking bolts, and then the inner connecting seat 1 is completely installed with the outer mounting seat 2 for sliding limit. The pressure sensor 21 will sense the pressure information and transmit the pressure information to the control component 31 inside the inner connecting seat 1.
