Intermediate yarn-free bottom raising device

The utility model relates to the technical field of computerized flat knitting machines, and discloses an intermediate yarn-free bottom raising device which comprises a mounting plate, a bottom raising plate, a horizontal displacement assembly and a vertical displacement assembly, and the horizontal displacement assembly and the vertical displacement assembly are used for driving the bottom raising plate to move in the horizontal direction and the vertical direction. The bottom lifting plate can move between the working position and the idle position, and the working position and the idle position are not in the same vertical direction, so that when the bottom lifting plate is in the idle position, the space occupied by the bottom lifting plate is avoided or reduced, the sight of workers cannot be blocked, and sufficient operation space is reserved for the workers; and replacement and maintenance work is facilitated, and wide-range popularization and application are facilitated. 本实用新型涉及电脑横机技术领域，公开了一种零间纱起底装置，包
