• a resistance structure 80 is disposed on the locking member 355.
• the telescopic portion 52 is operated to drive the slidable member 571 to overcome the resistance structure 80 to move. That is to say, when the applied external force reaches a certain value, the telescopic portion 52 drives the slidable member 571 to pass over the resistance structure 80. That is to say, when the telescopic portion 52 is fully stretched or fully extended, a certain thrust is required to overcome the resistance structure 80, so that the slidable member can pass over the resistance structure 80, thereby preventing the telescopic portion 52 from stretching and retracting randomly.

• the buffer portion 83 is squeezed by the slidable member 571, the buffer portion 83 is elastically deformed toward the hollow portion 81.
• the resistance of the resistance structure 80 needs to be overcome before the telescopic portion can be folded or unfolded, so that the telescopic portion 52 cannot stretch and retract freely. In this way, it is safe and reliable.
• the number of the resistance structures 80 may be but is not limited to one, two, or more, and the structure and shape of the resistance structure are not limited to those described in this embodiment.
• the external force applied to the telescopic portion 52 is used to overcome the resistance of the resistance structure 80 by pushing or pulling.

• the elastic force of the buffer portion 83 is overcome by the thrust, the slidable member passes over the buffer portion 83 to be in a fully stretched state (as shown in FIG. 19 to FIG. 20).
• the bed frame structure 100 stands stably, and the bed frame structure 100 can be used as a crib.
• the bed frame structure 100 When the bed frame structure 100 needs to be used as a bedside bed, the bed frame structure 100 is moved close to the adult bed.
• the telescopic portion 52 abuts against the adult bed, and the telescopic portion 52 overcomes the elastic force of the reset portion 59 and retract into the body portion 351 due to the external force, thereby driving the locking member 355 to slide toward the fixing portion 57.
• the telescopic portion 52 Under the guiding action of the slidable member 571 and the sliding portion 551, the telescopic portion 52 is retracted into the body portion 351 to be in the retracted state, so that the bed frame structure 100 is closer to the adult bed.

• the support leg 5 is operated to be in the unfolded state, and the first portion 315 does not apply pressure to the driving portion 70.
• the driving portion 70 is stretched to drive the snapping member 3711 to be unlocked from the positioning member 553.
