The invention relates to a locking and releasing device based on a cam type structure, the locking and releasing device comprises a locking base, two fasteners, a cam, two sliding shafts, a pin puller, a pressing rod and a load connecting mechanism, the upper end of the pressing rod is connected with the load connecting mechanism, and the lower end of the pressing rod is located in the locking base; the lower ends of the two fastening pieces can be installed on the inner side of the bottom wall of the locking base in a left-right sliding mode, and the upper ends of the two fastening pieces are provided with clamping sections clamped to the lower ends of the pressing rods in a matched mode. A cam shaft is arranged on the inner side of the bottom wall of the locking base, and the cam is rotationally connected to the cam shaft. The two sliding shafts penetrate through the two fastening pieces in a left-right sliding mode, each sliding shaft is sleeved with an unlocking spring, the two ends of each unlocking spring abut against the two fastening pieces respectively, the left ends of the two sliding shafts abut against the fastening piece on the left side in a limited mode, and the right ends of the two sliding shafts are connected and positioned through a connecting check block. The two sides of the cam abut against the connecting check block and the right side fastening piece respectively. The pin puller is installed on the locking base and can clamp and release the cam.
