A retention structure of a crossbow contains a fixer including a seat, a rolling element, a resilient element, and a shock absorber. The seat has an affix sheet, a fitting tube, at least one threaded aperture, an accommodation aperture, and an engagement portion. A diameter of the engagement portion is less than that of the accommodation aperture. The seat contacts with the connection mount. At least one screwing element screws with the at least one threaded aperture via the at least one locking orifice. The rolling element is housed in the accommodation aperture of the seat and is limited by the engagement portion. The resilient element is housed in the accommodation aperture and abuts against the connection mount and the rolling element. The shock absorber has a through hole and fits on the fitting tube of the seat by using the through hole.
