該桿體1具有一端部11，該端部11具有一第一耦合部，該第一耦合部於本實施例係由一由該端部11一體軸向延伸並呈圓球狀之凸塊12所構成，且該端部11有一第一肩部13，並有一呈環狀之第一板件14以緊配合方式套設於該端部11上並抵靠該第一肩部13，藉此可便於本發明之後續加工作業。The rod body 1 has an end portion 11, and the end portion 11 has a first coupling portion. In this embodiment, the first coupling portion is formed by a spherical protrusion 12 extending axially from the end portion 11 integrally. The end 11 has a first shoulder 13 and a ring-shaped first plate 14 is sleeved on the end 11 and abuts against the first shoulder 13 in a tight-fitting manner. It can facilitate the subsequent processing operations of the present invention.

該連接件2具有一第一端21以及一第二端22，該第一端21具有一可用與一動力工具(圖中未示)組接之連接段23，而該第二端22則具有一可與該第一耦合部配合之第二耦合部，本實施例中，該第二耦合部係由一縱斷面呈多邊形之凹槽24所構成，該連接件2並以其凹槽24與該桿體1之凸塊12相互耦接，而使該桿體1可相對該連接件2晃動，且該凸塊12與該凹槽24間具有一第一間隙A，該端部11與該連接件2之第二端22之間則具有一第二間隙B。另於該第二端22上形成有一第二肩部27，並有一呈環狀之第二板件28以緊配合方式套設於該第二端22上並抵靠該第二肩部27，使該第一板件14與該第二板件28呈間隔配置。The connecting member 2 has a first end 21 and a second end 22. The first end 21 has a connecting section 23 that can be assembled with a power tool (not shown), and the second end 22 has A second coupling part that can be matched with the first coupling part. In this embodiment, the second coupling part is composed of a groove 24 with a polygonal longitudinal section. The protrusion 12 of the rod body 1 is coupled to each other, so that the rod body 1 can sway relative to the connecting member 2, and there is a first gap A between the protrusion 12 and the groove 24, and the end 11 and There is a second gap B between the second ends 22 of the connecting member 2. In addition, a second shoulder 27 is formed on the second end 22, and a ring-shaped second plate 28 is sleeved on the second end 22 in a tight fitting manner and abuts against the second shoulder 27, The first plate 14 and the second plate 28 are arranged at intervals.

該包覆層3於本實施例中為具有彈性之橡膠材質，且該包覆層3包覆於該桿體1、該連接件2之一部份、該第一板件14以及該第二板件28，並填入該第一間隙A以及該第二間隙B，而使該桿體1與該連接件2彼此定位，但該桿體1受外力時仍可些微相對該連接件2晃動。本實施例中，該連接件2之連接段23外露於該包覆層3外。於本實施例中，該包覆層3更可透過該凹槽24之縱斷面呈多邊形之設計，讓該凹槽24與該凸塊12之間的第一間隙A形成有一緩衝層34，藉此當該桿體1晃動時，該凸塊12可透過該緩衝層34而減少與該凹槽24直接抵靠，提供較佳之緩衝。In this embodiment, the coating layer 3 is made of elastic rubber material, and the coating layer 3 covers the rod body 1, a part of the connecting member 2, the first plate member 14 and the second plate member 14 The plate 28 is filled with the first gap A and the second gap B, so that the rod 1 and the connecting member 2 are positioned relative to each other, but the rod 1 can still slightly sway relative to the connecting member 2 when subjected to an external force . In this embodiment, the connecting section 23 of the connecting member 2 is exposed outside the covering layer 3. In this embodiment, the cladding layer 3 can be further designed with a polygonal longitudinal section of the groove 24, so that the first gap A between the groove 24 and the bump 12 forms a buffer layer 34. Thereby, when the rod body 1 shakes, the bump 12 can pass through the buffer layer 34 to reduce the direct abutment with the groove 24, and provide better cushioning.

該包覆層3另於對應該第一板件14與該第二板件28之位置形成有一擴大部31，而於對應該桿體1之位置形成有一可供手部握持之握持部32，且該擴大部31之徑長大於該握持部32之徑長。於本實施例中，該第一板件14與該第二板件28上分別開設有複數個呈環狀配置之穿孔141、281，且該包覆層3填滿該各穿孔141、281並包覆該第一板件14與該第二板件28，藉此讓該包覆層3更加穩固包覆該第一板件14與該第二板件28。亦由於該擴大部31及該第一板件14與該第二板件28，使該擴大部31不致因太軟而不易操控或折斷。The covering layer 3 is further formed with an enlarged portion 31 at a position corresponding to the first plate 14 and the second plate 28, and a holding portion for holding by the hand is formed at a position corresponding to the rod body 1. 32, and the diameter of the enlarged portion 31 is greater than the diameter of the grip portion 32. In this embodiment, the first plate 14 and the second plate 28 are respectively provided with a plurality of through holes 141, 281 arranged in a ring shape, and the coating layer 3 fills the through holes 141, 281 and The first plate 14 and the second plate 28 are covered, so that the covering layer 3 more stably covers the first plate 14 and the second plate 28. Also due to the enlarged portion 31 and the first plate 14 and the second plate 28, the enlarged portion 31 is not too soft to be manipulated or broken.

於本實施例中，該連接件2之連接段23形成有一外螺紋231。In this embodiment, the connecting section 23 of the connecting member 2 is formed with an external thread 231.

另搭配第4、5圖所示，該包覆層3填滿該該連接件2第二端22與該桿體1端部11間之第二間隙B而形成一壓縮區33，藉此當該桿體1相對該連接件2晃動時，該壓縮區33可透過其材質之特性而分別彈抵該桿體1端部11與該連接件2第二端22，藉以減緩該桿體1相對該連接件2晃動時之幅度。In addition, as shown in Figures 4 and 5, the coating layer 3 fills the second gap B between the second end 22 of the connecting member 2 and the end 11 of the rod body 1 to form a compression zone 33, whereby When the rod 1 is swayed relative to the connecting member 2, the compression zone 33 can press against the end 11 of the rod 1 and the second end 22 of the connecting member 2 respectively through the characteristics of the material, thereby slowing the rod 1 relative to each other. The amplitude when the connecting piece 2 shakes.

藉由上述結構，當該動力工具因其機械運轉而使該輔助握把產生震動時，該輔助握把可透過該桿體1以其凸塊12組設於該連接件2之凹槽24設計，使該桿體1可以相對固定於該動力工具上的連接件2晃動，藉此有效減緩使用者握持該輔助握把時的震動。With the above structure, when the power tool vibrates the auxiliary grip due to the mechanical operation of the power tool, the auxiliary grip can be designed to pass through the rod body 1 and set in the groove 24 of the connecting piece 2 with its convex block 12 , So that the rod body 1 can sway relative to the connecting member 2 fixed on the power tool, thereby effectively reducing the vibration when the user holds the auxiliary grip.

惟，以上實施例之揭示僅用以說明本發明，並非用以限制本發明，故舉凡等效元件之置換仍應隸屬本發明之範疇。However, the disclosure of the above embodiments is only used to illustrate the present invention, not to limit the present invention, so any replacement of equivalent elements should still belong to the scope of the present invention.
