Abstract

The invention discloses a lighted nock device, including a nock body, an LED, a battery, a conductive mounting base, a conductive shift block and an on-off component arranged between the conductive shift block and the conductive mounting base to control connection and disconnection of the conductive shift block and the conductive mounting base. Connection and disconnection of the battery and the LED can be achieved quickly, so that the LED can be turned on or off quickly, with convenient operation and recycling use.

Claims
