Generally, the walker main body 100 in the present embodiment can be detached by the horizontal connecting rod 120 for easy storage, and the two armrest frames 110 can be connected by the horizontal connecting rod 120 more conveniently, and the horizontal connecting rod 120 and the two armrest frames 110 can form better protection for patients.

In this embodiment, referring to fig. 2 to 3, connecting blocks 310 are formed to protrude from both ends of the horizontal link 120 in the axial direction, and connecting grooves 320 for sliding engagement with the connecting blocks 310 are formed in the horizontal and lateral directions in depth at the armrest horizontal portion 111.

Specifically, in use, an assembler can insert the connection blocks 310 at both ends of the horizontal link 120 into the corresponding connection grooves 320, respectively, thereby achieving the preliminary connection between the horizontal link 120 and the armrest frame 110.

In this embodiment, referring to fig. 3, a clamping groove 311 is formed at the connecting block 310 along the depth along the horizontal and longitudinal directions, and referring to fig. 4, the control assembly includes a clamping block 410 capable of sliding along the horizontal and longitudinal directions and being clamped in the clamping groove 311.

Further, in use, after the two ends of the horizontal connecting rod 120 are initially connected with the armrest frame 110 through the connecting block 310, an assembler can clamp the clamping block 410 arranged in the armrest horizontal portion 111 into the clamping groove 311 of the connecting block 310 through the control assembly, so that further fixed connection between the horizontal connecting rod 120 and the armrest frame 110 is realized, and further connection stability between the horizontal connecting rod and the armrest frame 110 is ensured.
