摘要:
An arrow launching apparatus includes a bow attachment assembly and an arrow guide assembly. The front end of the arrow guide assembly is connected to the bow attachment assembly such that the arrow guide assembly is oriented perpendicularly with respect to the bow attachment assembly. The arrow guide assembly is adapted to receive an arrow for launching and includes a pair of longitudinally extensible and retractable front-end guide track assemblies located at the front end of the arrow guide assembly. Each of the front-end guide track assemblies includes a front telescopic segment and a rear telescopic segment. A plurality of spacer supports are connected to the front-end guide track assemblies and support the front-end guide track assemblies a predetermined distance from one another. A pair of transversely rotatable joint assemblies are provided. A first elastic resilient member is connected between the front telescopic segment and a front joint link for urging the front telescopic segment and the rear telescopic segment to a retracted orientation with respect to each other. A pair of transversely rotatable rear-end guide track assemblies are provided, wherein each rear-end guide track assembly is connected to a respective joint assembly. A bow string guide assembly is connected between the rear-end guide track assemblies at the rear end of the arrow guide assembly. The front joint link includes a stop portion located between the rear telescopic segment and a rear-end housing tube of a respective rear-end guide track assembly.
