For example, the eccentric wheel on the jaw crusher is connected with the movable plate to enable the movable plate to be intermittently close to the static plate, and the eccentric wheel is hinged with the sliding block through a connecting rod on a crank press to convert the rotary motion of the eccentric wheel into the reciprocating linear motion of the sliding block.

Example 2

Merely as an example of the practical application of the present invention, and not as a limitation of the present invention, the deflection transmission mechanism is applied to the crushing apparatus as an impact mechanism in the embodiment having the push rod 8 and the output shaft 21 described in embodiment 1. Referring specifically to fig. 9-11, the crushing device comprises a fixed plate 13 and a movable plate 14, the movable plate 14 is connected with the push rod 8 on the deflection transmission mechanism through a connecting plate 16, and a supporting block 15 is arranged below the movable plate 14.

The deflection transmission mechanism is used as an application of the impact mechanism in the crushing device, and of course, the deflection transmission mechanism can be used in other devices, where the other devices can be, for example, the impact or vibration type devices of embodiment 2, and can also be non-impact or vibration type devices, and as long as the deflection transmission mechanism realizes optimization of power transmission distance and spatial layout, or realizes external torsion, power size adjustment, power output convenience, and the like, the deflection transmission mechanism is specifically applied to the deflection transmission mechanism. For example, the device can be used as a clean energy application device in terms of power transmission distance design and spatial layout, and the direct utilization of clean energy can be realized by connecting a wind power driving component to the input shaft 31 instead of the motor 12. In addition, the deflection transmission mechanism can be manufactured as an independent integrated component in a standardized way, and is separated from a working component (such as the crushing device in the embodiment 2) in practical application as a separate device, so that the original integrated heavy mode can be simplified, the maintenance is convenient, and more favorable conditions are provided for the manufacturing, supplying and standardizing of the device.
