相應之套設所述固接板40上之導柱42，頂升板70上之掛持 點相應地與固接板40上之彈性件46之一端相勾接。 參 然後將所述止擋件20組裝至固定板10之兩侧，止擋件 20之固接部22之第二固接點222與所述固定板10之第一固 接點12相固接（如焊接），使止擋件20固接至固定板10上。 最後將所述滑動板30組裝至固定板10上，滑動板30之 二導軌32配合所述固定板10之二侧邊。滑動板30之二側亦 為所述二止擋件20之夾持槽242所夾持。止擋件20之止擋部 26與所述滑動架50大致位於同一平面上，即所述止擋件20 之止擋部26大致位於所述固接板40與頂升板70之間，每一 止擋件20之第二止擋凸起266大致貼鄰所述滑動架50之彎 12 201006344 折桿52之一直線段524，且滑動架50之所述凸伸端542可滑 過所述止擋件20之止擋部26之第一止擋凸起264而被第二 .止檔凸起266所阻擋。則頂升機構100之組裝完成。 請參閱圖4及圖5，使用該頂升機構100時，於外力之作 _用下，所述滑動板30相對固定板10滑動，滑動板30帶動所 述固接板40、滑動架50及頂升板60—起相對固定板10滑 動。當滑至滑動架50之凸伸端542被所述止擋件20之第二止 擋凸起266所阻擋時，則滑動架50停止滑動，而滑動板30 ©仍於外力之作用下沿原滑動方向滑動，且由於與滑動板30 固接之固接板40上之導柱42穿過頂升板70上之引導孔74， 則滑動板30仍帶動頂升板70 —起滑動。此時，頂升板70之 楔形凸起72相對滑動架50上之楔形體59滑動，則頂升板70 為楔形體59所頂升，即頂升板70相對固接板40及滑動架50 抬升。該過程中，所述固接板40上之擋柱44仍沿原方向滑 動，則迫使滑動架50之擺動塊58發生旋轉，且使得擺動塊 58之另一端轉入至止擋件20之夾持槽242内，且滑動套60 ❿位於夾持件56之一端與夾持件56之抵觸分開。當頂升板70 之楔形凸起72滑至滑動架50之楔形體59之頂部後，停止外 力作用，即滑動板30及頂升板70停止沿原方向滑動，此時， 頂升板70完全抬升，所述彈性件46之彈性形變最大，擺動 塊58之轉入夾持槽242内之一端亦轉至貼鄰擋件20之第一 止擋凸起264，且滑動套60—端抵觸滑動架50之彎折桿52 之彎折段522。 當頂升板70需退回時，於外力作用下，滑動板30連同 該頂升板70沿原滑動方向之反方向滑動，此時滑動架50僅 13 201006344 與固接板40具有一定之摩擦力，且在初始滑動架50之凸伸 端542為止擋件20之第一止擋凸起264所阻擋，因此滑動板 30返回滑動之初始不足以帶動該滑動架50同滑動板30及頂 貧 升板70—起以相同速度滑動。則頂升板70與固接板40相對 ‘滑動架50滑動，當頂升板70之楔形凸起滑至滑動架50之楔 形體59之第一傾斜面592時，在彈性件46之彈力作用下，頂 升板70快速下降，頂升板70之楔形凸起72之第二傾斜面重 新與滑動架50之楔形體59之第一傾斜面592相互貼合。此 φ時，所述固接板40相對滑動架50亦滑動一定之預設距離， 即恰好固接板40上之滑動套60重新抵觸至夾持件56之一 端，且擺動塊58亦回復至頂升板70之楔形凸起72與滑動架 50之楔形體59貼合時之原狀態。如此滑動板30與頂升板70 可再次帶動滑動架50 —起沿返回方向滑動，直至滑回到原 來滑動板30相對固定板10之位置。則滑動架50之凸伸端542 重新遠離所述止擋件20。 請參閱圖6，將所述頂升機構100應用至一攜帶式電子

Referring to FIG. 3, when the jacking mechanism 100 is assembled, the two straight segments 524 of the sliding frame 50 are respectively sleeved by the sliding sleeve 60, and the sliding sleeve 60 is fixed to the fixing plate 40 (such as welding). ), the carriage 50 is assembled to the fixing plate 40, and one end of each of the swinging blocks 58 of the sliding frame 50 respectively abuts against one of the blocking posts 44 of the fixing plate 40. The fixing plate 40 is then fixed to the sliding plate 30 to provide a plurality of fixed φ nails (not shown), and the fixing nail passes through the second fixing hole 48 of the fixing plate 40 and the sliding plate 30 A fixing hole 34 is fixed to the fixing plate 40 and the sliding plate 30. The jacking plate 70 is then assembled to the fixing plate 40, and the second inclined surface of each of the wedge-shaped projections 72 of the jacking plate 70 and the first inclined surface 592 of the wedge body 59 on the corresponding carriage 50, respectively. The guiding holes 74 on the jacking plate 70 are correspondingly sleeved on the guiding posts 42 on the fixing plate 40, and the hanging points on the jacking plate 70 are correspondingly connected with the elastic members 46 on the fixing plate 40. One end is hooked. The stoppers 20 are then assembled to the two sides of the fixing plate 10, and the second fixing points 222 of the fixing portions 22 of the stoppers 20 are fixed to the first fixing points 12 of the fixing plate 10. (such as welding), the stopper 20 is fixed to the fixing plate 10. Finally, the sliding plate 30 is assembled to the fixed plate 10, and the two guide rails 32 of the sliding plate 30 are fitted to the two sides of the fixing plate 10. The two sides of the sliding plate 30 are also clamped by the holding grooves 242 of the two stoppers 20. The stop portion 26 of the stopper member 20 is substantially in the same plane as the carriage 50, that is, the stopper portion 26 of the stopper member 20 is substantially located between the fixing plate 40 and the jacking plate 70, and each The second stop projection 266 of a stop member 20 is substantially adjacent to the straight line segment 524 of the fold 12 of the slide frame 50 201006344, and the protruding end 542 of the carriage 50 can slide over the stop The first stop projection 264 of the stop 26 of the stop 20 is blocked by the second stop projection 266. Then the assembly of the jacking mechanism 100 is completed. Referring to FIG. 4 and FIG. 5 , when the jacking mechanism 100 is used, the sliding plate 30 slides relative to the fixing plate 10 under the action of the external force, and the sliding plate 30 drives the fixing plate 40 and the sliding frame 50 and The jacking plate 60 is slid relative to the fixed plate 10. When the sliding end 542 of the sliding frame 50 is blocked by the second stopping protrusion 266 of the stopper 20, the sliding frame 50 stops sliding, and the sliding plate 30 is still under the action of external force. The sliding direction slides in the sliding direction, and since the guide post 42 on the fixing plate 40 fixed to the sliding plate 30 passes through the guiding hole 74 on the jacking plate 70, the sliding plate 30 still drives the jacking plate 70 to slide. At this time, the wedge-shaped protrusion 72 of the jacking plate 70 slides relative to the wedge body 59 on the carriage 50, and the jacking plate 70 is lifted by the wedge body 59, that is, the jacking plate 70 is opposite to the fixing plate 40 and the carriage 50. Raise. During this process, the blocking post 44 on the fixing plate 40 still slides in the original direction, forcing the swinging block 58 of the sliding frame 50 to rotate, and the other end of the swinging block 58 is turned into the clamp of the stopper 20 The groove 242 is held in the groove 242, and the sliding sleeve 60 is located at one end of the clamping member 56 to be separated from the clamping member 56. When the wedge-shaped projection 72 of the jacking plate 70 slides to the top of the wedge body 59 of the carriage 50, the external force is stopped, that is, the sliding plate 30 and the jacking plate 70 stop sliding in the original direction. At this time, the jacking plate 70 is completely When the elastic member 46 is lifted up, the elastic deformation of the elastic member 46 is maximized, and one end of the swinging block 58 that is turned into the clamping groove 242 is also turned to the first stop projection 264 of the adjacent member 20, and the sliding sleeve 60 is end-sliding. The bent section 522 of the bending rod 52 of the frame 50. When the jacking plate 70 needs to be retracted, the sliding plate 30 and the jacking plate 70 slide in the opposite direction of the original sliding direction under the action of the external force.

And the first stop protrusion 264 of the blocking member 20 is blocked by the protruding end 542 of the initial sliding frame 50, so the initial return of the sliding plate 30 to the sliding is insufficient to drive the sliding frame 50 with the sliding plate 30 and the top lean The plate 70 is slid at the same speed. Then, the jacking plate 70 and the fixing plate 40 slide relative to the 'sliding frame 50. When the wedge-shaped protrusion of the jacking plate 70 slides to the first inclined surface 592 of the wedge body 59 of the carriage 50, the elastic force acts on the elastic member 46. Next, the jacking plate 70 is rapidly lowered, and the second inclined surface of the wedge-shaped projection 72 of the jacking plate 70 rejoins the first inclined surface 592 of the wedge body 59 of the carriage 50. When the φ is φ, the fixing plate 40 is also slid relative to the sliding frame 50 by a predetermined distance, that is, the sliding sleeve 60 on the fixing plate 40 is again in contact with one end of the clamping member 56, and the swinging block 58 is also restored to The wedge-shaped projection 72 of the jacking plate 70 is in the original state when it is attached to the wedge body 59 of the carriage 50. Thus, the sliding plate 30 and the jacking plate 70 can again drive the carriage 50 to slide in the returning direction until it slides back to the position where the original sliding plate 30 is opposed to the fixed plate 10. Then, the protruding end 542 of the carriage 50 is again away from the stopper 20.
