A kind of axis bolt anti-loose structure of orchard shears,It includes: a clipper ontology,One pairing latch fitting,One limit lantern ring,One positioning cap and one latch fitting is screwed togather,By what the first cutter hub of clipper this system what and the second cutter hub be pivoted link when,It is what pairing latch fitting and screws togather between latch fitting separately configured with a limit lantern ring and a positioning cap,It is mutually twisted positioning by being engaged fin inside the chimeric tooth wall and limit lantern ring of positioning cap,And screw togather latch fitting system cap is chimeric forms gearing with positioning,And limit sleeve ring system limits on fixed the first cutter hub of what,And then work as and screw togather latch fitting and the sealed fixed Hou of pairing latch fitting,So that again by positioning cap and limiting the snap-in location of lantern ring,Latch fitting spiral shell is dynamic loosens to prevent from screwing togather,Increase the stability person of the clipper body construction composition.一種園藝剪之軸栓防鬆結構，其包含：一剪具本體、一對合鎖件、一限位套環、一定位帽蓋以及一螺合鎖件，由於剪具本體係於第一刀體與第二刀體之樞設連結時，係於對合鎖件及螺合鎖件間另配置有一限位套環及一定位帽蓋，藉由定位帽蓋之嵌合齒壁與限位套環內部咬合凸肋相互咬合定位，且螺合鎖件係與定位帽蓋嵌合形成連動，而限位套環係限制固定於第一刀體上，進而當螺合鎖件與對合鎖件鎖合固定後，俾能再藉由定位帽蓋與限位套環之咬合定位，以防止螺合鎖件螺動鬆脫，增添該剪具本體結構組成之穩定性者。
