参见图 1、 图 2所示， 根据本实用新型的上述实施例， 为了使所 述定位部件 72起到限定的作用， 所述针塞 6上形成有适于与所述定 位部 72—端抵靠的限位部 61。 这样通过调节所述定位部件 72的移 动， 就可以控制所述针塞的最大行程。 所述限位部 61可以为形成在 所述针塞 6上的环状凸起，例如针塞 6为一侧直径较小刚好可以穿过 所述定位部件 72的中心，一侧较出可以卡在所述定位部件 72的端部。 这样的环状凸起在加工针塞 6时比较方便， 生产成本较低。 Referring to FIG. 1 and FIG. 2, in accordance with the above embodiment of the present invention, in order to make the positioning member 72 function as a limitation, the needle plug 6 is formed to be adapted to be in position with the positioning portion 72. Relying on the limit portion 61. Thus, by adjusting the movement of the positioning member 72, the maximum stroke of the needle plug can be controlled. The limiting portion 61 may be an annular protrusion formed on the needle plug 6, for example, the needle plug 6 has a smaller diameter on one side and can pass through. The center of the positioning member 72 can be caught at the end of the positioning member 72 at one side. Such an annular projection is convenient when processing the needle plug 6, and the production cost is low.

参见图 1、 图 2所示， 根据本实用新型的上述实施例， 所述定位 部 72另一端连接有定位部套筒 9， 所述定位部套筒 9固定在枪体 1 上，所述定位部套筒 9内壁上形成有与定位部 72外壁上对应的螺紋。 所述定位部套筒 9可以对所述定位部 72起到一定的支撑作用， 使喷 枪在使用过程中比较稳定，受到振动时，也不会对流量调节产生影响， 并且增加了喷枪的使用寿命。  Referring to FIG. 1 and FIG. 2 , according to the above embodiment of the present invention, the other end of the positioning portion 72 is connected with a positioning portion sleeve 9 , and the positioning portion sleeve 9 is fixed on the gun body 1 , and the positioning is performed. A thread corresponding to the outer wall of the positioning portion 72 is formed on the inner wall of the sleeve 9 . The positioning portion sleeve 9 can play a certain supporting role on the positioning portion 72, so that the spray gun is relatively stable during use, and does not affect the flow adjustment when subjected to vibration, and increases the service life of the spray gun. .

参见图 1、 图 2所示， 根据本实用新型的实施例， 所述针塞 6上 套设有对扳机施加反弹力的弹簧 10。 为了给喷情提供高压气体， 所 述枪体 1上可以设置有与所述扳机 5连接的气流开关 11。  Referring to Figures 1 and 2, in accordance with an embodiment of the present invention, the needle plug 6 is provided with a spring 10 that applies a repulsive force to the trigger. In order to supply a high-pressure gas to the squirt, the gun body 1 may be provided with an air flow switch 11 connected to the trigger 5.

尽管已经示出和描述了本实用新型的实施例，对于本领域的普通 技术人员而言，可以理解在不脱离本实用新型的原理和精神的情况下 可以对这些实施例进行变化，本实用新型的范围由所附权利要求及其 等同物限定。  While the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art The scope is defined by the appended claims and their equivalents.
