Description

CROSS REFERENCE TO RELATED APPLICATIONS This application is a continuation application of U.S. application Ser. No. 17/016,347, filed on Sep. 9, 2020. The content of the application is incorporated herein by reference. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stroller and a reversible mechanism thereof, and more specifically, to a stroller having a reversible mechanism for performing the handle reversing operation of the stroller conveniently and quickly and a reversible mechanism thereof. 2. Description of the Prior Art Rapid developed economics and technology provide people with various consumer products, such as an infant carrier (e.g. a stroller or an infant bassinet). The stroller not only allows an adult to operate it with one hand to reduce his burden when taking an infant out, but also makes the infant sit thereon comfortably. Thus, the stroller has become more and more popular in infant caring. With improvement of user demand for the stroller, the stroller design has been made progress for satisfying the user needs. Recently, a reversible stroller has become popular in infant caring due to the following advantages: 1. the reversible stroller can be transferred from a forward facing position to a rearward facing position for protecting the infant sitting thereon from strong light or strong wind; 2. the infant can see the caregiver's face to reduce his insecurity when the caregiver pushes the reversible stroller; 3. the reversible function can expand the infant's view. The reversible stroller is mainly divided into two types: one is the handle reversible type; the other is the seat reversible type. A stroller having a reversible handle is more popular with people since it is more convenient to operate than a stroller having a reversible seat. In general, a conventional stroller having a reversible handle allows that a user can operate a sliding sleeve disposed at a bottom end of the handle to release the handle and then rotate an upper end of the handle to perform a handle reversing operation. However, the aforesaid handle reversing process takes a long time to release and then reverse the handle, so as to make the user unable to complete the handle reversing operation quickly. Thus, it is necessary to design a stroller and a reversible mechanism thereof to make the reversing operation of the stroller quick and convenient for solving the aforesaid problems. SUMMARY OF THE INVENTION One purpose of the present invention is to provide a reversible mechanism for performing the handle reversing operation of a stroller conveniently and quickly. Another purpose of the present invention is to provide a stroller having a reversible mechanism for performing the handle reversing operation of the stroller conveniently and quickly. For achieving the aforesaid purposes, a reversible mechanism of the present invention is disposed on a stroller. The stroller includes a stroller frame and a reversible member pivoted to the stroller frame. The reversible mechanism locks the reversible member at different positions relative to the stroller frame and includes anchoring portions, a sliding sleeve, and a release handle. The anchoring portions are disposed on at least two different positions of the stroller frame. The sliding sleeve movably jackets the reversible member. The sliding sleeve is selectively engaged with any one of the anchoring portions for locking the reversible member at the different positions relative to the stroller frame. The release actuator is movably disposed on the reversible member and linked with the sliding sleeve. The sliding sleeve is switched between a locking position and a releasing position with movement of the release actuator or is directly operated for locking or releasing the anchoring portion. The reversible member includes a joint structure including a cutout portion. The release actuator includes an operating portion, and the release actuator is disposed on the reversible member in such a manner that the operating portion is disposed in the cutout portion and is slidable along a lengthwise direction of the reversible member through operating the operating portion. Preferably, the joint structure includes a first joint and a second joint pivoted to the first joint, and the cutout portion is disposed on one of the first joint and the second joint. Preferably, the operating portion protrudes from the cutout portion. Preferably, a driving member is slidably disposed in the reversible member and linked with the sliding sleeve, and the sliding sleeve is slidably disposed on the reversible member along the lengthwise direction of the reversible member; when the release actuator is operated, the release actuator moves the driving member for driving the sliding sleeve to lock or release the anchoring portion. Preferably, the reversible mechanism further includes an elastic member disposed in the reversible member, the elastic member is disposed
