The ratchet type tensioner with the controllable pretightening force comprises an adjusting sleeve, two lifting lugs extending out of the two ends of the adjusting sleeve respectively, and a handle seat connected to the adjusting sleeve through a ratchet and pawl structure, and is characterized by further comprising a handle sleeve, the handle sleeve is connected with the handle seat through an overload protection mechanism, and the handle sleeve is connected with the handle seat through the overload protection mechanism. And when the handle sleeve is subjected to overload torque, the transmission connection between the handle sleeve and the handle seat is converted into rotating connection. According to the ratchet type tensioner with the controllable pre-tightening force, the handle sleeve is driven to apply the torque to the handle base so that the pre-tightening force applied to the binding and reinforcing device can be continuously increased till transmission connection between the handle sleeve and the handle base is changed into rotating connection, and it is indicated that in the current state, the binding and reinforcing device can be tightened. The applied pre-tightening force reaches the preset value, the process is easy and convenient to operate, an operator can visually know whether the magnitude of the pre-tightening force currently borne by the binding and reinforcing device is appropriate or not, and the operation time can be shortened.

    本申请提供一种预紧力可控的棘轮式张紧器,包括:调节套筒、分别伸出调节套筒两端的两个吊耳,以及通过棘轮棘爪结构连接于调节套筒的手柄座,其特征在于,还包括手柄套,手柄套与手柄座通过过载保护机构连接,以使手柄套受到过载的力矩时,手柄套与手柄座之间由传动连接转换为转动连接。本申请提供的预紧力可控的棘轮式张紧器,驱动手柄套对手柄座施加力矩以使本申请对捆绑加固装置所施加的预紧力不断升高,直至手柄套与手柄座之间由传动连接变为转动连接,则表明当前状态下,本申请所施加的预紧力已经达到预设值,该过程操作简便,能够使操作人员直观的获知捆绑加固装置当前所受到的预紧力大小是否合适,有助于缩短作业时间。
