Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, a kind of tensioning apparatus of elevator governor, including the fixed plate 2 being fixed on cage guide 12, Gu
There are two symmetrically arranged connecting plate 1, the internal activity of connecting plate 1 is connected with support plate 3, connecting plate 1 for the side connection of fixed board 2
Top surface offer caulking groove, support plate 3 is actively embedded in caulking groove, is connected between the bottom surface of support plate 3 and the bottom surface of caulking groove
