    • The female screw (8a) is formed on the inner circumference of the forward side of the piston receiving hole (8) in the cylinder body (2) and the movable stopper (9) is screwed into the female screw (8a). The piston (12) is located at the stroke end of the forward side when its end face of the forward side is contact with the end face of the backward side of the movable stopper (9). The rotating knob (4) is rotatably mounted on the end of the forward side of the cylinder body (2). The rotation transmitting pin (16) is projected on the end face of the backward side of the rotating knob. The rotation transmitting hole (9a) is formed on the end face of the forward side of the movable stopper (9). The rotation transmitting pin (16) is slidably inserted into the rotation transmitting hole. When the rotating knob (4) is rotated, the movable stopper (9) is screwed into so that the stroke end position and the moving stroke of the piston (12) can be adjusted.
    • 内螺纹(8a)形成在缸体(2)中的活塞接收孔(8)的前侧的内周上,可动止动件(9)旋入阴螺纹(8a)中。 当其前端的端面与可动止动件(9)的后侧的端面接触时,活塞(12)位于前侧的行程端。 旋转旋钮(4)可旋转地安装在气缸体(2)的前侧的端部。 旋转传递销(16)突出在旋钮的后侧的端面上。 旋转传递孔(9a)形成在可动止动件(9)的前侧的端面上。 旋转传递销(16)可滑动地插入旋转传递孔。 当旋转旋钮(4)旋转时,可动止动器(9)被拧入,从而可以调整活塞(12)的行程终点位置和移动行程。

    • In a connection surface (3c) of each of two members (1a, 1b) to be fastened, a communication groove (6) opened on a surface and an engagement groove (7) communicating therewith, being wider than the communication groove (6), and provided with a connection surface (9) parallel to the connection surface (3c) are formed. A fastener (8) includes: two engaging pieces (11), which can be inserted into the engagement grooves (7) and are wider than the communication grooves (6) and are provided with fastening surfaces (15); and a connecting portion (14) therebetween, wherein the entirety of the fastener (8) can be inserted into the interior of one set of communication groove (6) and engagement groove (7), which are opposed to and communicate with each other, by thrusting the respective engaging pieces (11) and connecting portion (14) thereto. In the inserted state, fastening surfaces (15) of the respective engaging pieces (11) contact with engagement surfaces (9) of the engagement grooves (7), thereby being unable to be pulled out in a direction orthogonal to the connection surfaces (3c) of the two members (1a, 1b). That is, the two members (1a, 1b) have nothing protruding from a surface by virtue of the fastening assembly, and are in a firmly fastened state via the fastener (8).
    • 在要紧固的两个构件(1a,1b)中的每一个的连接表面(3c)中,在表面上开口的连通槽(6)和与其连通的接合槽(7)比连通槽 (6),并且设置有与连接表面(3c)平行的连接表面(9)。 紧固件(8)包括:两个接合件(11),其可以插入到接合槽(7)中并且比连通槽(6)更宽并且设有紧固表面(15); 和其间的连接部(14),其中,所述紧固件(8)的整体能够插入到彼此相对并相互连通的一组连通槽(6)和接合槽(7)的内部, 通过将相应的接合件(11)和连接部分(14)推到其上。 在插入状态下,各接合片(11)的紧固面(15)与接合槽(7)的接合面(9)接触,不能沿与连接面(3)正交的方向拉出 c)两个成员(1a,1b)。 也就是说,两个构件(1a,1b)通过紧固组件从表面没有任何突出,并且通过紧固件(8)处于紧固状态。
