所选用的扭力扳手的开口尺寸必须与螺栓或螺母的尺寸相符合,扳手开口过大易滑脱并损伤螺件的六角,在进口汽车维修中,应注意扳手公英制的选择;各类扳手的选用原则,一般优先选用套筒扳手,其次为梅花扳手,再次为开口扳手,后选活动扳手。
The opening size of the selected torque wrench must be consistent with the size of the bolt or nut. If the opening of the wrench is too large, it is easy to slip off and damage the hexagon of the screw. In the maintenance of imported vehicles, attention should be paid to the selection of the metric and English system of the wrench. Generally, the socket wrench is preferred, followed by the ring wrench, then the open wrench, and then the adjustable wrench.
(2)为防止扳手损坏和滑脱,应使拉力作用在开口较厚的一边,这一点对受力较大的活动扳手尤其应该注意,以防开口出现字形,损坏螺母和扳手。
(2) In order to prevent the wrench from being damaged and slipping, the pulling force should be applied on the thicker side of the opening, which should be paid special attention to for the spanner with larger force, so as to prevent the shape of the opening from damaging the nut and wrench.
扭力扳手是按人手的力量来设计的,遇到较紧的螺纹件时,不能用锤击打扳手;除套筒扳手外,其它扳手都不能套装加力杆,以防损坏扳手或螺纹连接件
The torque wrench is designed according to the strength of human hands. When encountering tight threaded parts, it is not allowed to hit the wrench with a hammer; except for socket wrench, other spanners can not be equipped with a booster bar to prevent damage to the wrench or threaded connection parts
