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.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution:
A kind of sport power assisting device for sit-ups, including pedestal 13, the company of being fixedly installed on the upside of the pedestal 13
Fishplate bar 14 is fixedly installed with guide plate 2 on the upside of the connecting plate 14, is symmetrically installed with bar on the downside of 2 surface of guide plate, institute
It states the setting of guide plate 2 and is fixedly installed with support frame 1, the branch on the upside of 14 upper surface side of connecting plate, 2 surface of guide plate
Mirror holder 4 is fixedly installed on the upside of support 1,4 downside surface of mirror holder is fixedly installed with reflective mirror 3,14 right side of connecting plate
First swivel plate 8 is installed, first rotating shaft 12, first rotation are installed between first swivel plate 8 and connecting plate 14
It is fixedly installed with the first saddle 11 on the left of 8 upper surface of plate, is fixedly installed with the first air bag on the right side of 8 upper surface of the first swivel plate
