The four threaded holes 113 are rectangular and opened on the base plate 111. The four threaded holes 113 are respectively provided for four fixing bolts to pass through. The base plate 111 is installed on the wall of the bathroom by fixing bolts; the support plate 112 is vertically fixed to the base plate 111, and the two support plates 112 are symmetrically arranged on both sides of the base plate 111. In this embodiment, the support plate 112 and the base plate 111 are welded into one.

[0037] The handrail is installed on the wall, taking up space, resulting in a smaller space for activities in the bathroom. One end of the support rod 12 is connected to the base 11 for damped rotation. The support rod 12 can be rotated upward and flipped up to be stored, which is convenient for borrowing force while reducing the space occupied by the handrail and increasing the space for activities in the bathroom.

[0038] Specifically, refer to Figure 3 The support rod 12 includes an outer rod sleeve 121 and an inner round rod 122. The outer rod sleeve 121 and the inner round rod 122 are coaxially arranged. The outer rod sleeve 121 is sleeved on the inner round rod 122. The support rod 12 adopts a double-layer structure, which is more stable and improves the load-bearing capacity of the handrail.

[0041] Further, refer to Figure 1 、 Figure 2 The bottom of the support rod 12 is connected to abutment rod 141. When the support rod 12 is rotated until the axis of the support rod 12 is parallel to the horizontal direction, the end of the abutment rod 141 away from the support rod 12 abuts against the base 11. After the support rod 12 is rotated downward and flipped over, one end of the abutment rod 141 can abut against the base 11, thereby improving the stability of the armrest. The user can support himself on the support rod 12 and stand up conveniently.

[0042] One end of the abutment rod 141 is connected to a winding rod 142, and the winding rod 142 is for the roll of toilet paper to be mounted. When the abutment rod 141 abuts against the base plate 111, the winding rod 142 is located at the end of the abutment rod 141 away from the bottom, and the roll of toilet paper is mounted on the winding rod 142, making it convenient for the user to use toilet paper when going to the toilet.
