Abstract

본 발명은 트리거를 가벼운 힘으로 구동할 수 있고, 또 부품수가 적고, 조립이 간단한 구동장치를 제공하기 위한 것으로, 결치기어(31)는 2개의 결치부(34, 35)를 대향하는 위치에 갖고 있다. 구동기어(P)는 결치기어의 기어이부(32)에 맞물린다. 보유부(43, 71)는 결치기어를 결치부가 구동기어와 대향하는 위치에 유지한다. 트리거(11)는 이 보유부에 의한 결치기어의 상기 위치에서의 보유를 해제하여 결치기어의 기어이부를 구동기어에 맞물리게 한다. 작동용캠(45)은 결치기어에 설치되어 있다. 작동부재(50)는 제1작동위치와 제2작동위치의 사이를 이동자유롭게 설치할 수 있고, 결치기어의 회전시에 작동용캠과 걸어맞추어 반대측으로 이동한다. 반전탄성지지수단(61)은 작동부재의 이동에 의해 탄성변형되고, 그 반발력에 의해 그 작동부재를 제1작동위치 또는 제2작동위치에 택일적으로 위치시킨다.The present invention is to provide a drive device that can drive the trigger with a light force, has a low number of parts, and is easy to assemble. Have The drive gear P meshes with the gear teeth 32 of the gear. Retaining portions 43 and 71 hold the toothing gear at a position where the toothing portion faces the drive gear. The trigger 11 releases the holding at the position of the toothing gear by this retaining portion to engage the gear tooth of the toothing gear with the drive gear. The operation cam 45 is attached to the gear. The actuating member 50 can be installed freely between the first actuating position and the second actuating position, and moves to the opposite side in engagement with the actuating cam during rotation of the gear. The reversing elastic support means 61 is elastically deformed by the movement of the operating member, and alternatively positions the operating member in the first operating position or the second operating position by the repulsive force.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 구동장치의 실시예 1의 평면도로, 작동레버가 제1작동 위치에 있을때의 상태를 도시하는 도면,1 is a plan view of Embodiment 1 of the drive system of the present invention, showing a state when the operating lever is in the first operating position;

제2도는 동 구동장치의 평면도로, 작동레버가 제2작동위치에 있을때의 상태를 도시하는 도면.2 is a plan view of the drive device, showing a state when the operating lever is in the second operating position.

Claims

A toothing gear 31 having two toothing parts 34 and 35 at opposing positions, a drive gear P engaged with the gear teeth 32 of the toothing gear, and the toothing of the toothing gear And retaining the tooth in a position opposite to the drive gear, and releasing the retaining, trigger 11 to engage the gear tooth of the toothed gear with the drive gear, and an operating cam 45 mounted to the toothed gear; It is possible to move freely between the first operating position and the second operating position, when the engagement gear is rotated to the opposite side in engagement with the operation cam, when the attachment portion is opposed to the drive gear An inverted elasticity that is elastically deformed by the movement of the operating member 50 and the operating member 50 which is not in contact with the actuating cam, and by the repulsive force alternatively positioning the operating member in the first or second operating position. With supporting means (61) Drive device according to claim.

The method according to claim 1, wherein when the trigger is detached from the engaging portion, the trigger presses the actuating cam 41 installed on the engaging gear to rotate the engaging gear at an angle and engages the gear teeth with the driving gear. Drive device characterized in that.
