By rotating the guardrail frame 5 to the inside of the lower edge of the bed frame 2 after unlocking, the obstruction formed by the guardrail frame 5 during transfer can be reduced, and the patient can be smoothly transferred to the transfer bed. In this embodiment, the first crossbar 51 is in a segmented form, and a plurality of aligned first crossbars 51 are arranged in cooperation with a plurality of guardrail limiting blocks 23, and in actual use, a whole bar can also be used for rotation. The transition bar 52 is connected between the first crossbar 51 and the second crossbar 53 in the left-right direction, and the end of the transition bar 52 connected to the second crossbar 53 is bent upward at an angle of 90°, so that the second crossbar 53 is arranged parallel to the first crossbar 51; the third crossbar 54 and the second crossbar 53 are connected by a connecting rod 55, and the lower end of the connecting rod 55 is hinged to the second crossbar 53, and the upper end of the connecting rod 55 is hinged to the third crossbar 54; the third crossbar 54 and the second crossbar 53 are locked and fixed by the second locking mechanism 7. Through the above structure, the first crossbar 51 and the bed frame 2 can be rotated left and right while the second crossbar 53 and the third crossbar 54 are rotated forward and backward, so as to further facilitate the placement of the guardrail frame 5 under the bed frame 2, prevent the guardrail frame 5 from touching or pressing the patient during the transfer process, and further ensure the safety during the transfer process.
