The invention relates to a pigeon ankle bracelets structure. It is a flexible body with a coupling connection on one end or a body with a belt body. A wireless radio frequency identification tag is buried at an appropriate place of the body. A through-slot is set at another end of the body. A cutout slice capable of being torn off by external force is formed on outside wall of the through-slot. The end of belt body corresponding to through-slot is restraint end. The restraint end can wind around cutout slice by passing through the through-slot so as to form a closed ankle bracelet with the body for covering pigeon ankle. Inductive timer is used when pigeon arrives pigeonhole. The wireless radio frequency tag of body in the invention can sense time of arrival for register pigeon. If pigeon-clock timer is used, cutout slice can be torn off for winding around belt body to reduce external diameter of ankle bracelets so that time can be registered by throwing into pigeon-clock timer. Therefore, single ankle bracelets of the invention can be suitable for two kinds of timers with different properties.本發明係一種賽鴿腳環結構,其係一可撓彎的本體在一端扣合連結或是一體連伸一帶體,本體在適處埋設固定一無線射頻辨識標籤,本體的另一端設有貫通槽,於貫通槽外側壁形成一可為外力撕斷的可斷片,帶體對應貫通槽該端是約束端,約束端得穿過貫通槽繞覆可斷片,藉以與本體圍成封閉的腳環包覆鴿腳狀態,而當賽鴿抵達鴿舍,使用感應式計時器者,本發明在本體的無線射頻辨識標籤可供感測登錄賽鴿的到達時間,如果使用鴿鐘式計時器,則能撕斷可斷片,繞折帶體以縮小腳環外徑,即可投擲入鴿鐘式計時器來登錄時間,因此本發明的單一腳環可適用兩種不同性質的計時器。(10)...本體(11)...第一端(111)...固定槽(12)...第二端(121)...貫通槽(13)...第一環壁(14)...無線射頻辨識標籤(15)...突扣(16)...可斷片(30)...帶體(31)...固定端(32)...約束端(33)...第二環壁(34)...扣孔
