In this paper, a combined structure of ridge trimmer is created.The utility model comprises a ridge adjuster and a driving sleeve with a power drive.The driving sleeve is provided with a set of grooves along the axial direction and a limiting assembly located on the side wall of the grooves；And a massage piece includes a set of setting parts and at least one pushing part.The assembly part has a limiting ring groove.The group setting part is inserted in the group setting slot；The limiting massage piece is firmly fixed by pushing the limiting assembly into the limiting ring groove along the radial direction.And the limit assembly moves out of the limit ring groove along the radial direction to release the limit to pull out the massage piece.To achieve the operation that the driving sleeve firmly limits the combination and release of the massage piece,The utility model can effectively avoid the friction loss in the insertion and extraction operation of the massage piece relative to the driving sleeve.The durability of the structure can be extended.本創作一種整脊器組合結構，包括一整脊器結合具有動力驅動的一驅動套筒，該驅動套筒具有沿軸向設置的一組設槽及位於組設槽側壁的一限位組件；以及一推拿件包含有一組設部及至少一頂推部，組設部具有一限位環槽，該組設部插結於組設槽；藉由該限位組件沿徑向頂入限位環槽而牢固限位推拿件固定，且該限位組件沿徑向移出限位環槽解除限位以拔出推拿件，達到驅動套筒對推拿件牢固限位結合與釋放的操作，能有效避免推拿件相對驅動套筒插入與拔出操作中的摩擦損耗，而達到延長結構的耐久使用性。
