[0051] During use, when the mass block is corrected and guided by the correction parts 102 and the guide parts 103 to move onto the movable bottom plate 201a, the movable bottom plate 201a is extruded by the weight of the mass block to rotate downward around the connecting shaft 201b as an axis, the downward rotating movable bottom plate 201a will compress the supporting spring 201d to shrink and accumulate energy, and a top end abuts against the prying part 202 below the movable bottom plate 201a; when performing downward extrusion, the movable bottom plate 201a rotates around the rotating shaft 202b as an axis, and at this time, the downward pressing movable bottom plate 201a will push the whole locking part 203 from an inner side below the locking part 203 through the lever 202a in the form of the lever, so that the locking part 203 will rotate inward around the fixed shaft 104b as an axis, and a locking hook 203b at a top end of the rotating locking part 203 will be finally clamped and locked on the hook of the mass block, thereby achieving limiting in the horizontal direction and a locking function; when unlocking is required, an instruction is sent to the air cylinder 205a, the air cylinder 205a will push the push rod 205b outward, the outward pushed push rod 205b will abut against and be pushed on the triangular block 203d; due to the inclined surface structure of the triangular block 203d, when the push rod 205b extends out in the horizontal direction, an upward thrust can be applied to the whole locking part 203 through the triangular block 203d, so that the locking part 203 entirely moves upward; and the locking hook 203b at the top end will be separated from the hook, so that an unlocking function is achieved, and the mass block can slide on the device in the horizontal direction.

[0054] The active assembly 204b includes a vertical sliding rod 204b-1 arranged below the movable bottom plate 201a in a vertical state and first teeth 204b-2 arranged on a side surface of the vertical sliding rod 204b-1, where a top end of the vertical sliding rod 204b-1 abuts against a bottom surface of the movable bottom plate 201a, and the first teeth 204b-2 are engaged with the first gear 204a-2; and through the engagement of the first teeth 204b-2 and the first gear 204a-2, the first gear 204a-2 will be driven to rotate when the active assembly 204b moves in the vertical direction.
