A kind of pet excrement catching device,There is provided it is scalable/fold and fix accept angle effect,Comprising a body of rod,One be located at rod end pin joint seat,Rotation seat on one hub setting what pin joint seat,One is located at the ring body on rotation seat,And between pin joint seat and rotation seat,Equipped with one can multi-angle is chimeric fixes and the braking mould group of release pin joint seat and rotation seat,And it is fixed on ring body on pin joint seat with any angle by braking mould group； Thereby,Ring body can be folded toward the body of rod when unused,It does not take up space,It then can adjust the fixed angle of ring body when use,So ring body expanded angle can be adjusted according to bowl evacuation of pet situation,The imperfect situation of pickup will not also be generated by not landing excrement,Simultaneously rotation seat and pin joint seat are forced to fix using braking mould group,It is located in stability at any angle to promote ring body,The missing for overcoming the position stability of known ring body not good enough.一種寵物排泄物承接裝置，提供可伸縮/折收及固定承接角度的作用，包含一桿體、一設在桿體端部的樞接座、一樞置於樞接座上的轉動座、一設在轉動座上的環體，以及樞接座與轉動座之間，設有一可多角度嵌合卡固及釋放樞接座與轉動座的制動模組，而使環體藉由制動模組以任意角度固定在樞接座上；藉此，未使用時可將環體往桿體折收，不占空間，使用時則可調整環體的固定角度，如此可依寵物排便情形調整環體展開角度，使糞便不落地亦不會產生拾取不完整之狀況，同時利用制動模組將轉動座與樞接座強制固定，以提升環體定位在任意角度的穩固性，克服習知環體之定位穩定性欠佳的缺失。
