The axial direction of itself protrudes from the opposite latching portion 72. It must be noted that the latching portion 72 of the clutch cover 7 () may be a preferred embodiment as long as it has one. The clutch 8 has a casing (four), a pressing screw 82, a clutch 83, a resilient member, and a positioning member 86, wherein: as shown in the third and fourth figures, the housing 81 has a central portion A hole m' is provided for the second protrusion 334 of the bracket 33 and extends radially from the periphery thereof through a screw hole 814 of the communication shaft hole 812. In addition, the housing 81 has a capacity on one side. The slot 816' extends through a through hole 818 of a connecting pocket 816 from a peripheral edge thereof. A part of the hole wall of the through hole 818 has an internal thread, and the housing 8 ι extends through an adjacent hole 812 in the axial direction thereof and communicates with the positioning hole of the through hole 818. 819. The tightening screw 82 is screwed into the screw hole 814 of the housing 81 and its end top 6 201240708 is abutted against the second protrusion 334 of the bracket 33 for fixing the housing 81 to the bracket 33 so as to follow the bracket 33 synchronous rotation, as shown in the fourth figure. The clutch block 83 is located in the housing 816 of the housing 81 and is pivotally connected to the housing 81 by a pivot 87. The clutch block 83 can be offset from the housing 81 between a first position and a second position P2. When the clutch block 83 is in the first position pi, as shown in the fifth figure, one of the latching ends 832 of the latching block 83 protrudes from the receptacle 816 of the housing 81 and abuts against one of the clutch covers 7 The connecting portion 72' enables the clutch cover 70 to be synchronously rotated by the clutch 8〇. When the clutch block 83 is at the second position P2, as shown in the fourth figure, the latching end 832 of the clutch block 83 is received in the housing. The slot 816 of the 81 does not get stuck in the clutch cover 7 - the snap portion 72, so that the clutch 8 will be free to idle the clutch cover 70. The outer peripheral surface of the plug member 84 has an external thread so that the plug member 84 can be screwed into the through hole 818 of the housing 81. The elastic member 85 is disposed in the through hole 818 of the housing 81 and has an elastic member 852 and a top abutting member 854. One end of the elastic member 852 abuts against the plug material, and the top abutting member 854 is disposed at the other end of the elastic member 852. Between the clutch blocks 83, the one end of the clutch block 83 relative to the snap end can be pushed by the elastic member 852 to hold the clutch block 83 at the second position P2, as shown in the fourth figure. For the following: The above is the detailed structure of the electric starter 1G of the present invention. The following describes the operation process and features of the 201240708. The tooth motor 31 is driven to open the material, and the clutch 8 is rotated by the deceleration=group 32 to rotate the clutch 83 to receive the elastic force of the clutch 83, which is the off-state of the clutch, and the clutch 83 is the elastic force of the clutch 83. The clutch block 83, which is sufficient to overcome the elastic component 85 to be applied while remaining at the same time, does not produce a yaw relative to the person; 70 Ρ 2, as shown in the fourth figure, that is, the clutch 80 is relatively clutched | 70 free rotation. (10) When the motor is driven to increase the rotational speed of the clutch 8〇, the centrifugal force received by the clutch 83 of the clutch 80 is gradually increased, and once the elastic force provided by the clutch is released, the elastic member (4) of the member 85 is removed. The position ρ 亦 ; ; ; ; ; ; ; ; ; ; ϋ ϋ ϋ ϋ ϋ ϋ ϋ ϋ ϋ ϋ ϋ ϋ ϋ ϋ ϋ ϋ ϋ ϋ ϋ ϋ ϋ 83 83 83 83 83 83 83 83 83 83 83 83 83 83 83 83 83 83 83 At this time, the clutch cover 70 will be affected by the figure, the device __, and the transmission will be transmitted to the torque output shaft 50 as the clutch is sufficient. Thus, since the speed of the current = has been increased to the clutch unit The torque generated by the 60-handle sleeve from the torque output (4) is enough to spur the engine. After the engine is successfully started, the motor 3i will: The clutch 83 will be subjected to the second position of the elastic assembly 85 to release the engagement with the clutch cover w. <Q &A; Q & A 'Knocker's crankshaft (four) rushed and reversed 8 201240708 The regenerative force generated by the crankshaft of the engine in reverse is transmitted to the clutch via the gear transmission unit 4〇 The clutch cover 70 of the unit 60, at this time, because the clutch block 83 of the clutch 80 is held at the second position p2, that is, with the clutch portion 7 of the clutch cover 70, is kept in a separated state, therefore, the clutch cover The 7G is idling with respect to the clutch (10) while being subjected to the _power (4) until the feedback force disappears. In summary, it can be seen that the electric starter 10 of the present invention utilizes the design of the clutch unit 60 to store the power generated by the drive unit 3 to a predetermined value and then transmit it to the crankshaft of the engine of the remote model vehicle. The crankshaft of the engine obtains sufficient torque to quickly complete the starting of the engine. In addition, the clutch unit 6G will form an idle motion when receiving the feedback force from the crankshaft of the engine to release the lifting wheel set 32 and the wire drive unit 4. The transmission relationship between the rafts can effectively prevent the gear structure of both from being damaged. In addition, the elastic force applied to the clutch block 83 by the elastic member 852 of the elastic member 85 can be adjusted by the screwing relationship between the plug member 84 and the through hole 818. When the plug member 84 is locked tightly, the elastic member is loose. The larger the bomber provided to the clutch 83, in this case, the starting time of the motor 31 needs to be lengthened to increase the clutch H 8G _ speed, so that the clutch (10) clutch phantom obtains sufficient centrifugal force to overcome the slamming member 85.
