The sliding groove 22 is internally provided with a push-turn swinging slide block 23, and the push-turn swinging slide block 23 is embedded on the surface of high-strength alloy. A sliding block bearing 24 is further arranged between the push-turn swinging sliding block 23 and the sliding groove 22, the push-turn swinging sliding block 23 is in transmission fit with the linear sliding block 5 through a rotating shaft, and the push-turn swinging sliding block 23 is subjected to cross motion deflection under the thrust action of the linear sliding block 5 in the sliding groove 22 to drive the push-turn swinging arm 2 to rotate so as to drive the output shaft 21 to output. The invention connects the straight slide block through the connector and the middle thrust point of the reciprocating push rod, thus the connector and the reciprocating push rod can vertically and stably act on the straight slide block to move, compared with the traditional pushing and rotating mechanism, the connector and the reciprocating push rod can not generate single-side abrasion, the invention adopts the straight bearing to avoid being influenced by the deviation eccentric force, and the service life is longer.

All friction parts are in a rolling friction mode (the service life is longer compared with that of a traditional structure, the damping is smaller) and a rolling bearing mode, and the friction surfaces are made of embedded wear-resistant materials; the friction surface of the sliding groove of the push-rotating swing arm is made of embedded wear-resistant materials; the coupler and the reciprocating push rod adopt a rolling form of coating high-strength wear-resistant materials; lubricating grease is hidden in the linear bearing/linear guide rail, the slider bearing, the linear slider and the push rod linear bearing sleeve to become an oil-hiding bearing; the coupler and the base of the reciprocating push rod adopt linear bearings/linear guide rails, so that the friction force is small, the damping is low, the rigidity is good, the reciprocating precision is high, and the service life is ultra-long.
All friction parts of the invention are made of special materials and the rolling process method increases the wear resistance, reduces the friction force and reduces the damping function. 1. The friction coefficient of the rotating pusher is small and the damping is low in the moving process, so that compared with similar products, the output power of the rotating pusher is satisfied by the cylinder body with the same size; meanwhile, the operation stability is high, and the device is not jammed and does not creep. 2. All friction sites are treated with special materials and in the form of rolling friction. The surface of the coupler and the reciprocating push rod is hardened, and the friction shaft sleeve is replaced by a push rod linear bearing, and lubricating grease is contained in the coupler and the reciprocating push rod linear bearing, so that the coupler and the reciprocating push rod do not need to be injected with lubricating grease for long-term use.
