Description of the Invention: [Technical Field] The present invention relates to a trigger type liquid ejecting device (hereinafter also referred to simply as a liquid ejecting device) which is used in a container for accommodating a liquid. [Prior Art] Various liquid ejectors have been proposed which include a liquid ejecting body having a nozzle, a rotating member and a trigger lever, and a shroud covering the liquid ejecting body and by using the trigger lever The pulling operation is performed to eject the liquid from the ejection orifice of the nozzle. In the technique disclosed in Japanese Laid-Open Patent Publication No. Hei. No. 2-297219, a card protrusion protruding from each other is provided between the nozzle and the fitted rotary element, and an operation panel that rotates together with the nozzle is operated. The engaging projections are engaged with each other ' thereby positioning the nozzle at the discharge position of (4). ^ 匕 ' 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在. For this reason, it is feared that the engaging projection is cut or damaged due to the torque of the operating panel. In particular, = he, hehe, the nozzle will be subjected to the fitting pressure, and the second will cause the torque of the plate to act on the ladder to be used for the engagement protrusion. There is a possibility that the environmental stress is prevented from being caught in the inside of the nozzle by the engagement projections, and it is difficult to confirm the engagement state from the outside. There is also a two-pressure ejector that pulls the liquid from the nozzle by the pulling operation of the trigger rod, so that the liquid stored in the cylinder is blown out from the nozzle. Therefore, the trigger must be pulled. After the rod, the piston is subjected to the horizontal side 2: To this end, the previous liquid ejector makes this effect by rotating the trigger lever, pulling the center of the rotation from the nozzle and the force between the trigger rod and the piston = the point of action. The track of the point is close to the water, so that the force acts on the piston in a substantially horizontal direction. In the aspect of the invention, as disclosed in Japanese Patent No. 355, the liquid '^ 〇 is reserved to prevent the contents from being erroneously caused by the misoperation of the trigger lever, and the restriction mechanism of the mouth is attached, and when the restriction mechanism is attached, As described above, it is ideal: ideal. Also, such a liquid ejecting device should be small & so that it can be easily operated even with one hand. . The liquid ejecting device disclosed in Japanese Laid-Open Patent Publication No. 20064 3-6〇3 is attached to a fitting portion of a cylindrical portion extending from a nozzle opening hole opposite to a direction in which a liquid is ejected, and a rotating member. A groove is formed to form a flow path through which the liquid is ejected from the discharge hole. In such a liquid ejecting apparatus, the partial cross-sectional shape of the groove provided in the nozzle of the nozzle and the rotating element is not uniform (having a thin portion). For this reason, the liquid ejected as disclosed in Japanese Laid-Open Patent Publication No. Hei. No. 2006-136803 can be easily damaged to the temple in which the nozzle is rotated and the liquid is formed at a specific rotational position. In particular, since the nozzle is combined with other parts such as the rotating element, the nozzle is subjected to the combined pressure, and the liquid is liable to be damaged by the environmental stress, which may cause environmental stress damage. SUMMARY OF THE INVENTION 128871.doc 200920665 The present invention provides a trigger type liquid ejecting device, which is characterized in that: a nozzle and a liquid ejector body of a trigger rod; and a cover covering the body and the body of the device, and The liquid is ejected from the ejection hole of the nozzle by the pulling operation of the trigger lever, and the nozzle is disposed to be rotatable relative to the liquid ejecting body and is mounted on the nozzle by rotation.
