Abstract
An arrow retention device of a crossbow includes a fixing member which has one end thereof fixed to the shooting device, and an installation slot is defined axially in the underside of the fixing member. An arm is pivotably inserted into the installation slot and has a first end and a second end. The first end is exposed beyond the installation slot, and the second end of the arm is inserted into the shooting device. A restriction rod extends from each of two sides of the arm. A pushing spring connected to the top of the arm is biased between the second end of the arm and the shooting device. A retention member is connected to the arm and includes a contact portion for pressing an arrow. When shooting the arrow, the pushing spring pivots the arm back, and the contact portion is separated from the arrow.
