When the connecting part 41 is located in the middle section 422, the connecting part 41 extrudes the elastic part 43, and the protrusion 45 abuts against the elastic part 43. The protrusion 45 acts as a limiter when the elastic part 43 abuts against the connecting part 41, preventing the elastic part 43 from being excessively deformed when the connecting part 41 extrudes the middle section 422. This design ensures that the deformation of the elastic part 43 during each locking and unlocking process is within its elastic range, avoiding plastic deformation beyond the elastic limit, thereby prolonging the service life of the elastic part and ensuring the stability and reliability of the adjusting device.
