detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figures 1 and 2, the utility model includes: a power grip 1, a housing 2, a connecting rod 3, a driving wheel 4, a pinion 5, an inertia wheel 6, a generator 7, a spring 8, a large gear 9, and a driven wheel 10. The button 11, LED light 12, battery 13, bracket 14, etc. are assembled; the housing 2 is fixedly connected to the left handle of the power grip 1 through an arc-shaped surface, and the housing has a rectangular opening at the connecting rod. The handle is connected with the driving wheel 4 through the connecting rod, and both ends of the connecting rod are hinged; The rotating shaft and the inertia wheel 6 are coaxial, and the driving wheel 4 is not coaxial with its coaxial center, and the two shafts are supported by the bracket 14 fixed on the housing at the same time. The pinion 5 is linked with the generator shaft and the inertia wheel, and the power generation The machine is located between the small gear 5 and the inertia wheel, the large gear 9 and the driven wheel 10 are double gears; the driving wheel 4 is meshed with the driven wheel 10, and the large gear 9 is meshed with the small gear 5; Swing, drive the driving wheel 4 to rotate clockwise through the connecting rod, the driving wheel 4 meshes with the driven wheel 10, the driven wheel 10 rotates counterclockwise, the driven wheel 10 and the large gear 9 are double gears, the large gear 9 rotates counterclockwise, and the large gear 9 meshes with the pinion 5, the pinion 5 rotates clockwise, the four gears together form a secondary accelerator, the speed of the pinion 5 is far greater than the speed of the driving wheel 4, and the pinion 5 drives the generator 7 shaft and the inertia wheel 6 at a high speed Rotate, the moment of inertia of the inertia wheel is large, can drive the generator shaft to continue to rotate, and the elastic force and pulling force of the spring 8 can also promote the continuous rotation of the driving wheel 4 simultaneously.

As shown in Figure 3, it is the working state diagram when the power grip device 1 of the present utility model is relaxed. At this moment, the free end of the spring 8 is on the far right, and the spring is in a stretched state. This pulling force is overcome by the tension force of the power grip device spring, and the mechanism is in the state of In the static state, when the gripper starts to apply force, due to the pulling force of the spring 8 and the connecting rod 3, the driving wheel 4 rotates clockwise, and the rotating shaft of the generator 7 is driven by the speed changer.
