บรรทัด 2:
'''ไขควง''' ({{lang-en|screwdriver}}) คืออุปกรณ์ชนิดหนึ่งซึ่งออกแบบมาเพื่อขัน[[สกรู]]ให้แน่นหรือคลายสกรูออก ไขควงทั่วไปประกอบด้วยแท่ง[[โลหะ]] ส่วนปลายใช้สำหรับยึดกับสกรู ซึ่งมีรูปร่างแตกต่างกันเพื่อให้ใช้ได้กับสกรูชนิดต่าง ๆ และมีแท่งสำหรับจับคล้าย[[ทรงกระบอก]]อยู่อีกด้านหนึ่งสำหรับการไขด้วยมือ หรือไขควงบางชนิดอาจจะหมุนด้วย[[มอเตอร์]]ก็ได้ ไขควงทำงานโดยการส่ง[[ทอร์ก]] (torque) จากการหมุนไปที่ปลาย ทำให้สกรูหมุนตามเกลียวเข้าหรือออกจากวัสดุอื่น
ไขควงเป็นเครื่องมือสำหรับขันและคลาย สกรูชนิดหัวผ่า ขนาดและรูปทรงของไขควงถูกออกแบบให้เป็นไปตามลักษณะการ ใช้งาน เช่น ไขควงที่ใช้สำหรับงานของช่างอัญมณี (Jeweler's Screw Driver) จะออกแบบมาให้เป็นไขควงที่ใช้สำหรับงานละเอียดเที่ยงตรง ส่วนไขควงที่ใช้ในงานหนักของช่างเครื่องกลจะออกแบบให้ก้านใบเป็นรูปสี่เหลี่ยมจัตุรัสเพื่อให้ใช้ประแจหรือคีมจับขัน เพื่อเพิ่มแรงในการบิดของไขควงให้มากกว่าเดิมได้..........................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
