The invention discloses a fixing device for tea caddy processing and production. The fixing device for tea caddy processing and production comprises a shell, wherein a push rod is inserted into the top part of the shell; a trapezoid sliding block is fixedly connected to the top part, located in the shell, of the push rod; and a limiting cylinder is fixedly connected to the top part of the trapezoid sliding block. According to the fixing device for tea caddy processing and production, through the arrangement of the shell, and the cooperative use of the push rod, a push plate, the trapezoid sliding block, the limiting cylinder, moving rods, compression springs, sliding rods, sliding plates, fixing rods, clamping plates, a rotary rod and a bearing plate, the push rod is pressurized so as to drive the trapezoid sliding block to move, so that a limiting sleeve moves upwards so as to be sleeved in a tea caddy processing tank, and the tea caddy processing tank is fixed preliminarily; and thenthrough an elastic counter-acting force of the compression springs, the moving rods move along with the trapezoid sliding block so as to enable the fixing rods to push the clamping plates to move toward the middle part, and then the bearing plate is rotated to continuously press against the push plate, so that an effect on completely fixing the tea caddy processing tank is further achieved.
