上述的安全刀套， 其特点为： 所述限位件下端为楔形。
上迷的安全刀套， 其特点为： 所述限位凹槽由一定位玦与一带有楔面的导 向块组成， 所述定位玦位于刀托下部与套壳端口对应处， 所述带有楔面的 导向块位于所述刀托下部的中端。
上述的安全刀套， 其特点为： 所述套壳后部设置有半圆形缺口， 所迷 半圆形缺口设置在套壳端口中部。
上述的安全刀套， 其特点为： 所述套壳前端设有通孔。
上述的安全刀套， 其特点为： 所迷通孔为若干长奈形的孔。
上述的安全刀套， 将推扭装置与限位件相连接的方式， 使刀具能够锁 住在刀套中， 易于携带， 免去由于刀具脱离刀套而引发的伤害危险； 活动 刀托的使用， 使得刀锋护在刀托内， 不致伤害抽取刀时手执套壳的手； 刀 托的可滑动抽出及***， 既安全可靠、 易于携带、 方便使用又可方便清洁 刀套； 套壳上设有通孔， 易于及时疏干清洗刀具时遗留的水分， 通风通气， 使刀具不易生锈， 延长其使用寿命。

图 6为本发明套壳与活动刀托套接时端口处示意图
图 7为本发明活动刀托与限位件连接关系示意图
本发明的最佳实施方式
本发明是如下方式实施的：
如图 1 所示， 本发明包括套壳 1、 刀托 2及推钮 3, 套壳 1端口处没 置有推扭 3， 在推钮 3下部连接有一限位件 4， 限位件 4下端为楔形， 刀托 2与限位件 4相对的一侧下部设有一限位凹槽 6， 限位凹槽 6由一定位块 7 与一带有楔面的导向块 8组成， 定位块 7位于刀托 2下部端口处， 带有楔 面的导向块 8位于刀托 2下部的中端； 刀托 2顶部具有一限位凸起 10, 套 壳 1 内顶部设有一与刀托 2顶部限位凸起 10相对应的限位凹道 9; 推钮 3 上部连接一复位弹簧 5, 复位弹簧 5的另一端固定在套壳 1 内的上端； 在 刀托 2背面与套壳中部下端相接的位置上粘有一梯形片 21 , 梯形片 21的 下侧设有复位弹簧 51， 复位弹簧 51 —端固定在所迷套壳内的下端， 另一 端固定在套壳 1 内侧； 套壳 1上还设有通孔 12。
如图 2所示， 套壳 1前端处设有一排长奈形通孔 12, 经清洗后的刀具 放入刀套内， 可及时疏干清洁刀具时未甩开的水， 使刀具通风通气， 防止 刀具锈蚀。
如图 3、 图 4所示， 将推钮 3向上推， 推钮 3带动限位件 4上移， 使 限位件 4移出限位凹槽 6，刀托 2随之移出至套壳 1的端口处，此时刀托 2 顶部的限位凸起 10沿套壳 1顶部限位凹道 9移动， 卡在套壳 1的上端口 处， 限位件 4卡在套壳 1的下端口处， 使刀托 2不会从套壳 1 中脱出； 刀托 2上的梯形片 21随刀托 2移动而移动， 当刀托 2抽出套壳 1时， 梯形片 21下压复位弹簧 51， 梯形片 21随复位弹簧 51的未端倾斜， 刀托 2贴著套壳 1底部因倾斜而滑出， 使刀刃脱离刀套；
将刀具取出后， 将刀托 2推回套壳 1 内， 此时限位件 4沿著带有楔面 的导向玦 8的斜面移动，移动至限位凹槽 6处限位件 4落入限位凹槽 6内， 刀托 2复位。
当刀具需^刀套时， 拉出刀托 2, 此时梯形片 21也随著刀托 2的移 动方向移动， 将刀具波入刀托 2内推入， 刀托 2连梯形片 21—起随时弹簧 51滑入， 促使刀具安全进入套壳 1 中。
如图 5、 图 6所示， 套壳 1后面端口处中部设有半圓形缺口 11。
工业应用性
从以上具体实施例可以看出， 本发明具有以下优点：
1 . 推扭与限位件连接組合方式， 使刀具能够锁住在刀套中， 不会因携 带不妥造成刀具脱离刀套而引发的人身伤害；
2 . 活动刀托的设计， 使得刀锋护在刀托内， 不致伤害抽取刀时手执套 壳的手， 活动刀托的可滑动抽出及***， 既安全可靠、 易于携带、 方便使 用又可方便清洁套壳。
3 .套壳上设有通孔， 易于及时疏干清洗刀具时遗留的水分，通风通气， 使刀具不易生锈， 延长其使用寿命。
