Abstract:
Provided is a marble cartridge structure for combining a marble and a perforated liner tube, the structure comprising an inner liner tube cartridge, an upper positioning post cartridge cover, a marble, and a bent elastic pin, wherein the upper positioning post cartridge cover is fixed to the upper end of the inner liner tube cartridge; an outer circumferential face of the lower end of the inner liner tube cartridge is provided with a marble hole, and the marble is disposed in the marble hole; the bent elastic pin is supported in the inner liner tube cartridge, and the marble is connected to the bent elastic pin; the bent elastic pin is provided with a bent portion at an end proximate to the upper positioning post cartridge cover; and the upper positioning post cartridge cover is provided with a limiting slot that fits the bent portion. The limiting slot is used to prevent the bent elastic pin from being displaced, rotated, stuck or collapsed. The marble cartridge structure for combining a marble and a perforated liner tube provided in the present invention overcomes the defects of an existing marble tube structure in which an elastic pin is easily displaced, the bouncing height of a marble is insufficient, and the marble easily becomes stuck.
