The guiding portion 222 is provided with a sliding groove 223 on both sides, and each sliding groove 223 has a straight groove section 224 and an oblique groove section 225 connected to each other. Each oblique groove section 225 is inclined from the end of the guide portion 222 toward the direction of the hand cushion 5 and is connected to the straight groove section 224. The end of the guide portion 222 away from the hand cushion 5 has an oblique contact surface 226. The inclined direction of the inclined abutment surface 226 is the same as that of the inclined groove section 225, the side of the guide portion 222 has a side abutment surface 227 connected to the inclined abutment surface 226, the plug 3 has an insertion portion 31, and the insertion portion 31 It is movably inserted into the sliding hole 213, the insertion portion 31 respectively extends an extension portion 32 toward two sides of the guide portion 222, and each extension portion 32 extends toward the corresponding sliding groove 223 and slides with a sliding buckle portion 33, The insertion portion 31, each extension portion 32, and each sliding buckle portion 33 surround a buckling space 335 (fourth figure B), and the portion of the insertion portion 31 facing the buckling space 335 has a connected inclined surface 311 and a On the side surface 312, when the lifting switch 22 is operated by applying a force to the pressing portion 221, each sliding button portion 33 can be displaced in the corresponding sliding groove 223, so that the inserting portion 31 can be displaced in the sliding hole 213, and each sliding button portion When 33 is located in the corresponding straight groove section 224, the side contact surface 312 slides against the side contact surface 227, and the insertion portion 31 is inserted into the corresponding positioning hole 16, and each sliding buckle portion 33 is located in the corresponding inclined groove section 225, the inclined surface 311 can abut against the inclined surface 226, and the insertion portion 31 faces Inside displacement.

接續上述內容進一步詳述本發明之實施方式，如第三圖呈現這是尚未操作升降開關22時的狀態，而插栓3插設於滑孔213、對應的定位孔16，且如第三A、三B圖所示除滑扣部33位於直溝段224外，同時插部31也以側靠面312滑抵於側抵面227，以增加插栓3的穩定度，接續施力操作升降開關22便會如第四圖、第四A、四B圖所呈現，因升降開關22往手靠墊5之方向位移，滑扣部33滑離直溝段224而進入斜溝段225，同時插部31斜靠面311滑抵於斜抵面226，並經由斜溝段225、斜抵面226之導引使插栓3內縮，插部31移出原先所插設之定位孔16，此時升降組2便可以如第五圖所示相對基座1位移，接續操作使升降開關22使其復位，此時插栓3經由斜溝段225、斜抵面226之導引而朝對應之定位孔16伸出，且滑扣部33經由斜溝段225進入直溝段224，而直溝段224之結構得以使滑扣部33必須滑進斜溝段225，插栓3才開始向內位移，避免乘坐者手臂置放過程中稍微誤觸升降開關22就使升降組2因手臂之重量突然下降。 Continuing the above content, the embodiment of the present invention will be further described in detail. As shown in the third figure, this is the state when the lift switch 22 has not been operated, and the plug 3 is inserted in the sliding hole 213 and the corresponding positioning hole 16, as shown in the third A 3. As shown in Figure 3B, in addition to the sliding buckle portion 33 located in the straight groove section 224, the insert portion 31 also slides against the side abutment surface 227 with the side abutment surface 312 to increase the stability of the plug 3 and continue to apply force to operate the lifting The switch 22 will be as shown in the fourth, fourth A, and fourth B diagrams. Because the lift switch 22 is displaced in the direction of the hand cushion 5, the sliding button 33 slides away from the straight groove section 224 and enters the inclined groove section 225. The inclined surface 311 of the portion 31 slides against the inclined surface 226, and is guided by the inclined groove section 225 and the inclined surface 226 to retract the plug 3, and the insertion portion 31 moves out of the original positioning hole 16 at this time. The lifting group 2 can be displaced relative to the base 1 as shown in the fifth figure, and the continuous operation resets the lifting switch 22. At this time, the plug 3 is guided by the inclined groove section 225 and the inclined contact surface 226 to the corresponding position. The hole 16 extends, and the sliding button portion 33 enters the straight groove section 224 through the inclined groove section 225. The structure of the straight groove section 224 enables the sliding button portion 33 to slide into the inclined groove section 225 before the plug 3 starts to move inwardly , To prevent the occupant from touching the lifting switch 22 by mistake during the arm placement process, which would cause the lifting group 2 to suddenly drop due to the weight of the arm.

綜合上述內容可以得知，本發明之升降開關22除以滑溝導引滑扣部33來使插栓3活動位移外，進一步以斜抵面226、側抵面227來導引插栓3，以分擔滑扣部33之負擔、減緩滑扣部33之磨損速度，進而達到改善習知問題、提高產品耐用度之目的。 Based on the above content, it can be known that the lift switch 22 of the present invention uses the sliding groove guiding sliding buckle portion 33 to move the plug 3 and further uses the inclined abutment surface 226 and the side abutment surface 227 to guide the plug 3. To share the burden of the sliding button portion 33 and slow down the wear speed of the sliding button portion 33, thereby achieving the purpose of improving the conventional problems and improving the durability of the product.
