As shown in the first and second figures, a holder and a knife holder group (52) are provided on the holder (20). The engaging structure of the engaging structure, wherein the engaging structure can be at least one horizontally protruded from the blade seat (20) and engaged with the engaging groove (522) provided on the blade holder group (52) The card rib (21) is further provided at the front end of the blade holder (20) with a cutting hole (202) extending a certain length and for inserting a pencil therein, and a weight is arranged at the bottom of the front end of the blade holder (20) ( 29) 'To maintain the smoothness of the blade holder (20) as it rotates with the tool holder group (52), a two-phase spaced front support portion (22) and rear support portion are protruded from the top surface of the blade holder (20). 23), a housing space (24) is formed between the two supporting portions (22, 23), and the bottom of the receiving space (24) is in the shape of a hole and communicates with the cutting hole (202). A pair of axially opposite shaft holes (222, 232) are respectively disposed on the two supporting portions (22, 23), and a plate groove (25) adjacent to the rear supporting portion (23) is recessed at the rear end of the blade seat (20). In the plate slot (25) A squeezing block (252) is provided, and the arbor (30) is rotatably disposed on the shaft holes (222, 232) of the two supporting portions (22, 23) on the seat (20), and the arbor (30) The outer diameter is approximately equal to the inner diameter of the shaft hole (222, 232), so that the cutter shaft (30) is stably disposed between the two shaft holes | (222, 232), and a ring groove is recessed at the proximal end of the cutter shaft (30). ), the outer diameter of the cutter shaft (30) at the annular groove (302) is smaller than the inner diameter of the shaft hole (222) of the front support portion (22), and the rear end of the cutter shaft (30) is penetrated through the rear support portion (23) The shaft hole (232) extends into the slot (25). The spring (36) is sleeved on the front end of the cutter shaft (30) to provide a pushing force of the cutter shaft (30), so that the cutter shaft (30) is not formed at the annular groove (302) and the front support portion (22) The shaft holes (222) are matched, and the cutter shaft (30) is firmly disposed between the two shaft holes (222, 232), and the front support portion (22) of the knife seat (20) faces the seat φ (20) A retaining edge (27) is formed on a side surface of the front end, and a cover (28) is connected to the retaining edge (27), and a knife is formed between the retaining edge (27) and the cover (28). The front end of the shaft (30) projects into it and accommodates the space of the spring (36) and abuts one end of the spring (36) against the cover (28). The cutter (32) is rotatably sleeved on the cutter shaft (30) and accommodated in the accommodating space (24) of the seat (20), which may be in the form of a cylindrical hob or planer. The axis of the cutter (32) may be inclined at an angle to the axis of the seat (20), and the periphery of the cutter (32) may extend into the extended cutting hole through the hole at the bottom of the receiving space (24). In order to cut the pencil, and at one end of the cutter 201116420 (32), a set of gears (34) provided on the cutter shaft (30) is provided for the purpose of the gear (34) and the electric pencil sharpener. The transmission is connected such that the tool (32) can be driven to rotate relative to the seat (20) and the cutter shaft (30), and secondly, a set of the cutter (32) can be disposed at one end of the front end of the seat (20). a spacer (38) on the cutter shaft (30). The sliding plate (40) is slidably disposed at the bottom of the blade seat (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). 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). . In use, the user can insert a pencil into the body (50) of the pencil sharpener and the cutting hole (202) of the 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. Please refer to the sixth figure. When the pencil is cut to a predetermined degree, the sharpened tip will push against the stop surface of the sliding plate (40), 201116420 and push the sliding plate (40). Moving 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) can be driven against the blade shaft (30). The portion is swung toward the front side of the holder (2〇), and the pushing shaft (30) is moved toward the front side of the holder (2〇), and when the cutter shaft (3〇) moves to the ring groove (302) and the front support portion (22) When the shaft holes (222) are opposed, the outer diameter of the ring groove (302) of the cutter shaft (3〇) is smaller than the inner diameter of the shaft hole (222), so the shaft hole (222) cannot provide the cutter shaft (30). The effect of the stable support, at this time, 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 After the pencil is removed from the cutting hole (202), the recovery spring force provided by the spring (36) can be used to push the blade shaft (30) back to the shaft hole (222). Is set, and drive the support plate (42) and the slide plate (40) return to an original to be next pencil cutting operation. When the tool (32) is worn due to use, the tool module (1〇) can be extracted from the body (5〇) along the engaging groove (522) on the tool holder group (52), and the new The tool module (1〇) is replaced in the main body (5〇), so that the user can not discard the entire electric pencil sharpener, which can reduce the waste of resources and greatly reduce the use cost of the electric pencil sharpener.
