Shock absorber with limiting and shock absorbing composite functions

The invention discloses a damper with a limiting and damping composite function, and relates to the technical field of damping, in particular to a first connecting plate and a connecting rod, the rear end of the first connecting plate is provided with a first upper placing plate, the two sides of the front end of the first upper placing plate are provided with first buffer seats, and the interiors of the first buffer seats are connected with side shock absorbers. According to the shock absorber with the limiting and shock absorbing composite functions, in the using process of the whole shock absorber, targeted shock absorbing treatment can be conducted on shock generated in the upper direction and the lower direction of a first upper connecting plate and a lower connecting plate by utilizing shrinkage of a hydraulic rod to be synchronously matched with the design of a shock absorbing spring; and the design of a hydraulic rod and an externally-attached spring is used for carrying out preliminary cushioning tre
