在本实施例中，所述第二齿轮部212的齿槽深度小于所述第一齿轮部211的齿槽深度，所述第二齿条232的齿槽深度小于所述第一齿条22的齿槽深度，从而便于所述第二齿轮部212与所述第二齿条232的啮合。
所述第二齿条232为自所述支撑部231倾斜向下延伸形成，使得所述传动件23倾斜呈直线或弧形曲线，在本实施例中，所述传动件23倾斜呈弧形曲线，使得所述第二齿条232与所述齿轮21的啮合程度增加，便于所述齿轮21对所述第二齿条232的传动，进而使得所述传动件23易于向上移动。
所述第一齿条22设于所述齿轮21的上侧，所述传动件23为自所述支撑部231与所述盖体12连接处向前下方倾斜，所述第二齿条232啮合于所述齿轮21的右下侧，使得所述第一齿条22向前运动带动所述齿轮21逆时针转动，所述齿轮21带动所述传动件23向后上方移动而使所述盖体12向上且向后移动。
在其他实施方式中，所述传动件23可自所述支撑部231与所述盖体12连接处向后下方倾斜，所述第二齿条232啮合于所述齿轮21的右下侧，所述第一齿条22向前运动带动所述齿轮21逆时针转动，所述齿轮21带动所述传动件23向前上方移动而使所述盖体12向上且向前移动，同样的，所述第一齿条22还可设于所述齿轮21的下侧，所述传动件23可自所述支撑部231与所述盖体12连接处向后下方或前下方倾斜，相应的，所述第二齿条232啮合于所述齿轮21的左下侧或左上侧，使得所述第一齿条22向前运动带动所述齿轮21顺时针转动，所述齿轮21带动所述传动件23向前上方或后上方移动而使所述盖体12向上且向前移动或 向上且向后移动。
如图4至图7所示，所述盖体12具有向外延伸的第一支撑轴121，所述支撑部231为所述传动件23的整体长度的一段且材质为硬质材料，所述支撑部231远离所述第二齿条232的一侧卡箍于所述第一支撑轴121周侧，一方面使得所述支撑部231能够轻松带动所述盖体12升起或下降，另一方面便于拆装；在其他实施例中，所述支撑部231也可设置为整体固定于所述第一支撑轴121上，同样能够轻松带动所述盖体12升起或下降。
在本实施例中，所述第二齿条232材质为柔性材料，使得所述第二齿条232与所述齿轮21的啮合程度增加，便于所述齿轮21对所述第二齿条232的传动，进而使得所述传动件23易于向上移动，所述升降组件2还包括设于所述传动件23背离所述齿轮21一侧的限位机构24以避免所述第二齿条232与所述齿轮21脱离，便于所述第二齿条232与所述齿轮21的啮合。
如图8所示，所述升降组件2还包括固定于所述箱体1上的基座25，所述基座25设有容置所述传动件23的导向槽251，所述限位机构24为构成所述导向槽251侧壁的至少一部分，所述导向槽251上端具有开口2511以供所述支撑部231穿经所述开口2511与所述盖体12连接，所述基座25还具有连通所述导向槽251以容置所述齿轮21的齿轮槽252，能够避免所述第二齿条232与所述齿轮21脱离，便于所述第二齿条232与所述齿轮21的啮合。
所述盖体12还具有向外延伸的第二支撑轴122，所述升降组件2还包括支撑杆26和相对所述箱体1固定设置的固定机构27，所述支撑杆26的上端转动连接于所述第二支撑轴122，下端转动连接于所述固定机构27，所述抽屉10关闭时，所述支撑杆26倾斜设置，且当所述传动件23为自所述支撑部231与所述盖体12连接处向后下方倾斜时，所述支撑杆26的上端位于所述下端的后侧；当所述传动件23为自所述支撑部 231与所述盖体12连接处向前下方倾斜时，所述支撑杆26的上端位于所述下端的前侧，这样所述盖体12被所述传动件23带动向上且向后移动或向上且向前移动时，所述支撑杆26的上端被带动，而使其上下两端轴心对齐于竖直方向，能够在所述盖体12升起后起到辅助支撑作用，保证抽拉过程的稳定性。
如图8所示，所述基座25还设有容置所述支撑杆26的支撑槽253，所述固定机构27设于所述支撑槽253内壁上，所述支撑杆26连接于所述固定机构27的一端向外延伸有一对支撑脚261以在所述支撑杆26被所述盖体12带动至竖直状态时支撑于所述支撑槽253的底壁上，使得所述支撑杆26的支撑更稳定。
