[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Embodiment 1

[0028] Reference Figure 1-Figure 3 , a safety protection device for elevator maintenance, comprising:

[0029] Three fence panels 1;

[0030] Two connecting plates 2 are arranged between three fence plates 1 at intervals;

[0031] Four rotating shafts 5 are rotatably mounted on the two connecting plates 2 respectively;

[0032] Four mounting plates 4 are fixedly connected to four rotating shafts 5 respectively, and three fence plates 1 are fixedly connected to one side of the four mounting plates 4 respectively;

[0033] Six support plates 7 are rotatably mounted on both sides of the three fence plates 1, and are used to support the fence plates 1 on the ground so that the fence plates 1 are stably placed;

[0034] The locking mechanism is provided on the support plate 7 and is used to fix the support plate 7 .

[0035] In the present invention, the locking mechanism comprises six locking bolts 8 , and the six locking bolts 8 are respectively threadedly mounted on the six supporting plates 7 .
