Signal generator with stabilizing mechanism

The utility model relates to the technical field of signal generators, in particular to a signal generator with a stabilizing mechanism, which comprises a machine body, a heat dissipation device and a positioning block, heat dissipation holes are arranged on two sides of the machine body, the heat dissipation device comprises a fixing plate, through holes are arranged on the fixing plate and are symmetrically distributed, and the positioning block is arranged on the fixing plate. The fixing plate is located on one side of the heat dissipation holes and connected to the two sides of the machine body through fasteners, the side, away from the machine body, of the fixing plate is fixedly connected with a vertical frame, the positioning block is in a rectangular-ambulatory-plane shape, and the bottom of the positioning block is fixedly connected to the top of the machine body. The inner wall of the positioning block is fixedly connected with connecting columns which are symmetrically distributed; the heat dissipa
