摘要： An initial velocity accelerating tube includes an outer pipe. Two ends of the outer pipe are connected with a stop member and a connection member, respectively. An inner pipe is provided in the outer pipe. Two ends of the inner pipe are inserted in the stop member and the connection member, respectively. When the initial velocity accelerating tube is mounted on a toy gun, one end of the inner pipe is against the front end of the barrel of the toy gun by the elastic force of the elastic member so as to tightly connect the barrel, providing an airtight effect. The barrel can be lengthened. To have a shoot with the long-barreled gun, the bullet can have a longer route to accelerate for getting a higher initial velocity.
摘要翻译：初速加速管包括外管。外管的两端分别与止动构件和连接构件连接。内管设在内管内。内管的两端分别插入止动件和连接件中。当初始速度加速管安装在玩具枪上时，内管的一端通过弹性件的弹力抵靠玩具枪枪筒的前端，以紧紧连接枪管，提供气密影响。桶可以加长。要用长筒枪射击，子弹可以有更长的路线来加速获得更高的初始速度。

摘要： A piston structure for a toy gun includes a piston body and a detachable toothed member. The piston body has a chute which is axially disposed on an outer surface of the piston body. The detachable toothed member is made of a metallic material and moveably disposed in the chute. The detachable toothed includes a plurality of teeth which are equally spaced in a lengthwise direction. The piston structure of the present invention provides a longer service life. In case the teeth of the detachable toothed member suffer a lot of wear and tear, the detachable toothed member can be detached from the chute and replaced with a new one to save the cost and to provide an environmental protection effect.
摘要翻译：用于玩具枪的活塞结构包括活塞体和可拆卸的有齿构件。活塞体具有轴向设置在活塞体的外表面上的斜槽。可拆卸的有齿构件由金属材料制成并且可移动地设置在滑槽中。可拆卸齿包括沿长度方向等间隔的多个齿。本发明的活塞结构提供更长的使用寿命。在可拆卸齿形构件的齿受到大量磨损的情况下，可拆卸的齿形构件可以从滑槽上拆下并更换新的，以节省成本并提供环境保护效果。
