Abstract: This invention provides a tilt angle adjustable combined rat-proof device, relating to the technical field of rat-proof devices. A rat-proof device includes a rat-proof plate body, a fixing mechanism and an adjusting mechanism, wherein the rat-proof plate body is inserted into the fixing mechanism so that the rat-proof plate body is able to be clamped, and an upper end of the fixing mechanism is clamped into the adjusting mechanism and is able to slide along the adjusting mechanism so as to drive the rat-proof plate body to move, thereby realizing adjustment of the tilt angle of rat-proof plate body. The device can adjust the tilt angle based on the user's actual requirements, therefore adapting to the use environment, and it is also extremely convenient in the process of transportation, disassembly and installation.
