Anti-stabbing device for retaining sheet

The utility model discloses an anti-stabbing device for a retaining sheet, which comprises a retaining sheet base plate, the retaining sheet base plate is detachably mounted on a protective strip plate, a plurality of strip-shaped grooves along the sliding direction of the retaining sheet are arranged on the retaining sheet base plate, and the strip-shaped grooves are matched with the retaining sheet and limit the retaining sheet. According to the retaining sheet base plate, when the saw blade is obliquely cut, the retaining sheet can be supported to the edge of the groove of the retaining sheet base plate to move back and forth, and the situation that the retaining sheet slides out of the surface of the protective strip plate and pierces into a working table, and consequently the saw blade cannot ascend and descend is effectively prevented. 本实用新型公开了一种止退片防刺装置，包括止退片垫板，所述止退片垫板可拆卸安装在护条板上，所述止退片垫板上设置有若干沿止退片滑动方向的条状凹槽，所述条状凹槽与止退片适配并对止退片进行限位。本实用新型的止退片垫板在锯片倾斜切割时，可以使止退片支到止退片垫板的凹槽的边缘前后动作，有效防止止退片滑出护条板表面，刺入工作台面，造成锯片无法升降。
