This creation, which provides a kind of shear body, to be had teeth portion and is cut by the trunk of directly drive,One end of its holding section of its first actuator what has shear body,The front end of the linkage section of second actuator has plural number teeth portion and is hubbed on the pivot joint section of the shear body of the first actuator,The cut section what protrusion of second shear body has plural teeth portion and engages with the teeth portion of the first actuator,The cut section of second actuator can with respect to the cut section lateral displacement of the first actuator,And first the shear body of actuator the opening widths of two cut sections is limited with blocking portion blocking opposite with the blocking portion of the shear body of the second actuator,Thereby constitute this creation.本創作提供一種剪體具有齒部而被直接帶動之樹幹剪,其第一驅動件於其握持段的一端具有剪體,第二驅動件之連接段的前端具有複數齒部且樞設在第一驅動件之剪體的樞接段,第二剪體之剪切段於凸出部具複數齒部與第一驅動件之齒部嚙合,第二驅動件之剪切段可相對第一驅動件之剪切段側向位移,且第一驅動件之剪體以阻擋部與第二驅動件之剪體的阻擋部相對阻擋而限制二剪切段之開口寬度,藉此構成本創作。
