As shown in fig. 3, fig. 3 is a front view structure diagram of one side of the end portion of the armrest body, specifically a front view structure diagram of one side of the armrest body 1, which is away from each other at two ends, wherein the fixing shaft 10 is of a cylindrical structure, and the fixing shaft 10 is adapted to the shaft hole 9. Two fixed shafts 10 on the armrest main body 1 are correspondingly rotatably inserted into two shaft holes 9 in the accommodating groove 3, so that the armrest main body 1 can be rotatably arranged in the accommodating groove 3.

With continued reference to fig. 1, a horizontal groove 4 communicated with two ends of the accommodating groove 3 is further disposed on the inner wall of the elevator car 2, and two ends of the horizontal groove 4 are correspondingly communicated with the inner wall of one side of the accommodating groove 3, where the two ends are close to each other. Two sliding blocks 5 are slidably connected in the horizontal groove 4, and the sliding blocks 5 are slidably assembled in the horizontal groove 4, which belongs to the prior art and are not described in detail herein. And be located between two sliders 5 in the horizontal groove 4 and be provided with dead lever 6, dead lever 6 passes through fixed block 11 and fixes between two parties in horizontal groove 4, and dead lever 6 is cylindrical shaft-like structure and both ends are unsettled form in horizontal groove 4.

Furthermore, two ends of the fixing rod 6 are correspondingly inserted into the two sliders 5 in a sliding manner and are respectively connected with the two sliders 5 through springs 7, and the two sliders 5 are respectively provided with a locking head 8 which can be inserted into the handrail main body 1 and lock the handrail main body 1.

Specifically, the two sliders 5 are provided with insertion holes 12 at their ends adjacent to each other, the two ends of the fixing rod 6 are correspondingly inserted into the insertion holes 12 of the two sliders 5 in a sliding manner, and a spring 7 is disposed in the insertion hole 12 of each slider 5. One end of the spring 7 is fixedly connected with the inside of the jack 12, and the other end of the spring 7 is fixedly connected with the end part of the fixed rod 6. One end of each of the two sliders 5, which is away from each other, is provided with a locking head 8, as shown in fig. 2, fig. 2 is a schematic structural diagram of an end front view of the locking head provided by an embodiment of the present invention, and the locking head 8 is a rod-shaped structure of a regular polygon. As shown in fig. 4, fig. 4 is a front view structure diagram of the other side of the end portion of the handrail main body, specifically a front view structure diagram of one side of the handrail main body 1 where the two ends are close to each other, and one side of the handrail main body 1 where the two ends are close to each other is respectively provided with a locking groove 13 for the locking heads 8 on the two sliders 5 to correspond to the inserted regular polygon.
