述驱动机构 60带动卡托滑块 31沿滑轨 20的方向往复运动。 通过该驱动机构 60, 可实现卡托滑块 31的往复运动,
[0047] 进一步的, 所述驱动机构 60包括电机 61、 皮带 62及定位轮 63(亦可为同步轮), 所述卡托滑块 31还设置有连接件 32并通过连接件 32与皮带 62固定连接, 以在电 机 61工作吋, 带动皮带 62及卡托滑块 31运动。 皮带 62套设在电机 61的同步轮及 定位轮 63上, 电机 61工作吋带动皮带 62运动, 由于皮带 62与卡托滑块 31固定连 接, 固定在皮带 62运动吋可带动卡托滑块 31—起运动。 [0048] 具体的, 所述滑轨 20为单轨, 所述单轨的两侧设有卡槽, 所述卡托滑块 31卡接 于卡槽中。 卡托滑块 31与单轨卡接配合, 使得卡托滑块 31稳定地沿单轨方向往 复运动。
[0049] 综上, 本申请至少具有如下优点:
[0050] 1、 测试卡 70采用前置前出方式, 在测试前将测试卡 70收集框置于仪器下方, 当测试完成后测试卡 70从仪器前方推出直接掉落至测试卡 70收集框中, 节省操 作人员人力;
[0051] 2、 允许测试完成后的测试卡 70在仪器外部堆积不影响正常退卡, 操作人员无 需做完一次测试就要收集一次废测试卡 70, 避免操作人员频繁操作带来的人力 浪费;
[0052] 3、 退卡 (废测试卡 70)与进卡共用同一套驱动, 简化了结构, 提高了稳定性, 降 低了整机成本;
[0053] 4、 主动式退卡, 保证废测试卡 70顺利滑出仪器。
[0054] 以上所述仅为本申请的优选实施例, 并非因此限制本申请的专利范围, 凡是在 本申请的申请构思下, 利用本申请说明书及附图内容所作的等效结构变换, 或 直接 /间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
