[0043] 处理盒第二实施例
[0044] 作为对本发明处理盒第二实施例的说明， 以下仅对与处理盒第一实施例的不同 之处进行说明。
[0045] 参见图 5至图 8， 限位机构 23由销钉 231、 弹簧 232和盖部件 233构成， 盖部件 233 固定在容纳腔 220沿传递齿轮 22轴向的外端口上， 在容纳腔 220平行于传递齿轮 2 2的轴向的内壁 2202上幵设有两个活动槽 223， 两个活动槽 223相对于传递齿轮 22 的轴线呈对称布置， 每个活动槽 223均沿着传递齿轮 22的轴向自容纳腔 220的外 端口向内延伸， 销钉 231的两端分别位于两个活动槽 223内， 销钉 231与活动槽 22 3之间形成有间隙， 即活动槽 223在垂直于自身延伸方向的宽度大于销钉 231的直 径， 以便于销钉 231能够在活动槽 223中活动， 使销钉 231既能够沿着传递齿轮 22 的轴向往复移动， 也能够以传递齿轮 22的轴线为中心轴做小幅度的转动。
[0046] 盖部件 233的内表面设有插入活动槽 223的凸块 234， 凸块 234与活动槽 223过盈 配合， 将盖部件 233固定在传递齿轮 22的端部， 另外， 在盖部件 233的径向中心 部位幵设有中心孔 235， 中心孔 235的直径略大于传输杆 211的直径， 以便于传输 杆可以在中心孔 235内往复移动。 本实施例中， 限位部指的是凸块 234。
[0047] 此外， 固定件也可为螺钉， 传输杆上幵设有在径向上贯穿传输杆的螺纹孔， 螺 钉与螺纹孔配合。 传输杆的横截面也可以为多边形， 相应地容纳腔与传输杆的 形状相对应。 弹簧也可以采用橡胶等其他弹性件替代。 上述这些改变均可实现 本发明的目的。
[0048] 由上述方案可见， 采用柱状的传输杆， 通过其输入齿接收主机的驱动机构提供 的旋转驱动力， 限位机构中固定件和弹簧的配合使旋转力传递件在传递齿轮的 容纳腔内沿着传递齿轮的轴向做往复运动， 与现有技术相比， 避免了旋转力传 递件从传递齿轮脱落的风险， 从而保证旋转力传递组件在传递驱动力吋具有良 好的可靠性和稳定性， 同吋有效地简化了旋转力传递组件的结构。 固定件可拆 卸地固定在传输杆上便于实现装拆。 柱状的传输杆结构简单且加工工艺简单， 有助于提高生产效率。
[0049] 最后需要说明的是， 以上所述的仅是本发明的优选实施方式， 应当指出， 对于 本领域的普通技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干 变形和改进， 这些都属于本发明的保护范围。
[0050] 工业应用性
[0051] 本发明的处理盒可以安装到激光打印机等电子照相成像设备中， 处理盒的旋转 力传递组件作为处理盒的一个组件， 用于接收电子照相成像设备输出的旋转力 ， 并且带动处理盒的显影元件、 感光鼓或者充电元件旋转。
[0052] 由于本发明的旋转力传递组件中， 传输杆可以沿传递齿轮的轴向往复移动， 并 且通过限位机构的限位作用， 传输杆能够以传递齿轮的轴线为中心轴做小幅度 的转动， 这种结构在避免了现有技术中旋转力传递件从传递齿轮脱落的风险， 还能使得处理盒安装吋落机平稳， 传输驱动力吋性能可靠、 工作稳定， 且该处 理盒安装及拆卸方便。
