Connected so that the tool (32) can be driven to rotate relative to the seat (20) and the cutter shaft (30), and secondly, one set of the cutter can be disposed on one end of the cutter (32) toward the front end of the seat (20) A spacer (38) on the shaft (30).
該滑動板(40)係可滑動地設置於刀座(20)的底部，其可略呈L形彎折，而於前端形成有一直立的止擋面(402)，而於後端形成一橫向的連接面(404)，於連接面(404)上設置有一連接孔(406)，另於止擋面(402)之兩側分別凸設形成有兩間隔之夾合片(403)，而於刀座(20)底部兩側分別凸設形成有可夾合於所相對夾合片(403)之間的導引肋(26)，藉由夾合片(403)與導引肋(26)的相互配合，可令滑動板(40)相對刀座(20)滑動。The sliding plate (40) is slidably disposed at the bottom of the blade holder (20), and may be slightly L-shaped, and has an upright stop surface (402) formed at the front end and a lateral direction formed at the rear end. a connecting surface (404), a connecting hole (406) is disposed on the connecting surface (404), and two spaced apart clamping pieces (403) are respectively protruded on both sides of the stopping surface (402), and The two sides of the bottom of the knife seat (20) are respectively formed with guiding ribs (26) that can be sandwiched between the opposing clamping pieces (403), by the clamping piece (403) and the guiding rib (26) The mutual cooperation allows the sliding plate (40) to slide relative to the seat (20).
該支撐板(42)係可擺動地連接至滑動板(40)上，並容置於刀座(20)的板槽(25)內，且其兩側面分別與板槽(25)內的推抵塊(252)及刀軸(32)之後端相抵靠，於支撐板(42)底部凸設形成有一可擺動地結合於滑動板(40)上連接孔(406)的連接凸部(422)。The support plate (42) is swingably connected to the sliding plate (40) and received in the plate groove (25) of the knife seat (20), and the two sides thereof are respectively pushed with the plate groove (25) The abutting block (252) and the rear end of the cutter shaft (32) abut against each other, and a connecting convex portion (422) swingably coupled to the connecting hole (406) of the sliding plate (40) is formed at a bottom of the supporting plate (42). .
在使用時，使用者可將鉛筆***削鉛筆機的本體(50)及刀座(20)的切削孔(202)內，並透過電動削鉛筆機的驅動裝置帶動刀架組(52)及刀具模組(10)同時相對本體(50)轉動，並以一傳動裝置使刀具(32)相對刀座(20)自轉，以藉此切削所***的鉛筆。In use, the user can insert the pencil into the body (50) of the pencil sharpener and the cutting hole (202) of the blade holder (20), and drive the knife holder group (52) and the cutter through the driving device of the electric pencil sharpener. The module (10) is simultaneously rotated relative to the body (50) and the cutter (32) is rotated relative to the seat (20) by a transmission to thereby cut the inserted pencil.
請再配合參看第六圖，當鉛筆被切削至預定的尖度後，此時被削尖的筆尖會推抵到滑動板(40)的止擋面(402)，並推動滑動板(40)相對朝向刀座(20)的後端移動，隨著滑動板(40)的滑移及推抵塊(252)的推抵，可帶動支撐板(42)與刀軸(30)相抵靠的部位朝向刀座(20)前側擺動，而推抵刀軸(30)朝向刀座(20)前側移動，當刀軸(30)移動至其環槽(302)與前支撐部(22)的軸孔(222)相對時，因刀軸(30)環槽(302)處的外徑小於軸孔(222)的內徑，故軸孔(222)並無法提供刀軸(30)穩固支撐的效果，此時，刀具(32)則會相對刀座(20)呈可擺動狀態，如此便不會持續地切削鉛筆，以避免過度切削鉛筆的情況產生；當使用者將削尖後的鉛筆自切削孔(202)中取出後，即可利用彈簧(36)所提供的恢復彈力，推動刀軸(30)回復至與軸孔(222)穩固配合的位置，並帶動支撐板(42)及滑動板(40)回復至原位，以待下次的鉛筆切削作業。Please refer to the sixth figure again. When the pencil is cut to a predetermined degree, the sharpened tip will push against the stop surface (402) of the sliding plate (40) and push the sliding plate (40). Relative to the rear end of the blade holder (20), with the sliding of the sliding plate (40) and the pushing of the pushing block (252), the supporting plate (42) and the blade (30) can be driven to abut against each other. Swinging toward the front side of the holder (20), and pushing the cutter shaft (30) toward the front side of the holder (20), when the cutter shaft (30) moves to the ring hole of the ring groove (302) and the front support portion (22) (222) In the opposite direction, since the outer diameter of the ring groove (302) of the cutter shaft (30) is smaller than the inner diameter of the shaft hole (222), the shaft hole (222) cannot provide the stable support of the cutter shaft (30). At this point, the tool (32) will be swingable relative to the seat (20), so that the pencil will not be cut continuously to avoid excessive cutting of the pencil; when the user will sharpen the pencil from the cutting hole After being removed in (202), the recovery spring force provided by the spring (36) can be used to push the cutter shaft (30) back to a position that is firmly matched with the shaft hole (222), and drive the support plate (42) and the sliding plate ( 40) Revert to the original position to wait for the next lead Pen cutting operation.
而當刀具(32)因使用而有磨耗時，可將刀具模組(10)沿刀架組(52)上之卡合槽(522)而由本體(50)中抽出，並將新的刀具模組(10)更換置入本體(50)內，如此使用者可不需丟棄整個電動削鉛筆機，可減少資源的浪費，並能大幅降低電動削鉛筆機之使用成本。When the tool (32) is worn due to use, the tool module (10) can be extracted from the body (50) along the engaging groove (522) on the tool holder group (52), and the new tool can be taken. The module (10) is replaced in the main body (50), so that the user does not need to discard the entire electric pencil sharpener, which can reduce the waste of resources and greatly reduce the use cost of the electric pencil sharpener.
