[0008] The utility model is further provided with a first sliding groove formed on one side of the fixed plate, and a sliding block movably installed in the inner wall of the first sliding groove, and a limiting block is fixed on one side of the sliding block and movably connected with the slide plate.

[0009] As preferably, through the first sliding slot and the sliding block are matched with each other, the sliding plate moves longitudinally.

[0010] The utility model further sets up, one side of sliding plate is equipped with second sliding slot, and the inner wall of second sliding slot is pasted with the outer wall of limit block.

[0011] As preferably, through the limit block and the second sliding slot are matched with each other, the movement direction of the sliding plate is limited, so that the sliding plate can only move along the direction of the limit block.

[0012] To sum up, the utility model mainly has the following beneficial effects:

[0013] The utility model discloses a slow -moving support for keyboard, including bottom plate, fixed plate, slow -moving motor, connecting rod, connecting support, carousel, eccentric shaft, support platform and sliding plate, the bottom plate is equipped with fixed plate, the fixed plate is equipped with slow -moving motor, the slow -moving motor is equipped with connecting rod, the connecting rod is equipped with connecting support, the connecting support is equipped with carousel, the carousel is equipped with eccentric shaft, the eccentric shaft is equipped with support platform, the support platform is equipped with sliding plate, the sliding plate is equipped with sliding block and limit block.
