Rolling massaging device

DETAILED DESCRIPTION The main object of the present invention is to provide a massaging device Which has massaging balls that can be kept evenly distributed on a cord when the massaging device is in use, thus resulting in an effective massaging action.
Another object of the present invention is to provide a massaging device with, a connecting unit which can join effectively the two ends of the cord without affecting adversely the appearance of the massaging device.
Accordingly, the massaging device of the present invention comprises a cord, a plurality of massaging balls and a plurality of biasing units strung on the cord, each of the biasing units being disposed respectively between adjacent two of the massaging balls, and a connecting unit for joining two ends of the cord together.
Each biasing unit includes a hollow round bead which consists of left and right bead halves that are formed as complementary hemispherical shells.
The bead halves confine a respective receiving space and are formed with aligned cord holes to permit extension of the cord therethrough.
Each biasing unit further includes a coiled compression spring sleeved on the cord and extending into the receiving spaces of the bead halves.
The spring biases the bead halves away from each other.
The connecting unit includes left and right connectors formed as complementary hemispherical members which engage respectively the two ends of the cord.
The left connector has an annular abutting end and a connecting portion which is surrounded by the abutting end and which includes a tubular shank that is formed with an external screw thread.
The right connector has an annular abutting end and a connecting portion which is surrounded by the abutting end and which includes an annular recess that is confined by a surrounding wall formed with an internal screw thread for engaging the external screw thread.
