In order to realize that the transmission shaft 52 only drives one of the full-row gear 531a and the half-row gear 531b to rotate when rotating in one direction, and the other one of the full-row gear 531a and the half-row gear 531b is kept stationary, in this embodiment, the full-row ejector rod 30a and the half-row ejector rod 30b are respectively provided with a second limiting part 31 which is in limiting fit with the first limiting part 12 on the knob body 10; when the transmission shaft 52 rotates forward, the second limiting part 31 on the half-row ejector rod 30b is in limiting fit with the first limiting part 12 to limit the half-row ejector rod 30b to slide along the direction opposite to the extending direction of the half-row ejector rod 30b, so that the half-row abutting block 521b is separated from the half-row fitting block 54 b; when the transmission shaft 52 rotates reversely, the second position-limiting portion 31 on the full row of push rods 30a is in position-limiting fit with the first position-limiting portion 12 to limit the full row of push rods 30a to slide along the direction opposite to the extending direction of the full row of push rods 30a, so that the full row of abutting blocks 521a are separated from the full row of fitting blocks 54 a. Specifically, a full-row sleeve 13 and a half-row sleeve 14 are arranged on the knob body 10, a full-row ejector rod 30a is slidably sleeved in the full-row sleeve 13, a half-row ejector rod 30b is slidably sleeved in the half-row sleeve 14, and a first limiting portion 12 is formed at the outer end edges of the full-row sleeve 13 and the half-row sleeve 14.

In other embodiments, the first position-limiting portion 12 and the second position-limiting portion 31 may not be provided, that is, when the transmission shaft 52 rotates forward, the full-row abutting block 521a abuts against the full-row matching block 54a to drive the full-row gear 531a, and the half-row abutting block 521b and the half-row matching block 54b may keep abutting state and not separate under the action of the half-row torsion spring connecting the two, at this time, the half-row push rod 30b slides along the direction opposite to the extending direction of the half-row push rod 30b under the action of the half-row gear 531b and the half-row rack 532b to retract into the knob body 10; when the transmission shaft 52 rotates reversely, the half-row abutting block 521b abuts against the half-row matching block 54b to drive the half-row gear 531b, the full-row abutting block 521a and the full-row matching block 54a can keep the abutting state without separation under the action of the full-row torsion springs connecting the half-row and the full-row matching blocks, and at the moment, the full-row ejector rod 30a can slide along the direction opposite to the extending direction of the full-row ejector rod 30a under the action of the full-row gear 531a and the full-row rack 532a to retract into the knob body 10. Therefore, when the knob body 10 is designed in this way, one of the full-line push rod 30a and the half-line push rod 30b is extended, and the other is retracted into the knob body 10, the internal space of the knob body 10 needs to be large.
