Detachable and torque adjustable cross wrench

A detachable and torque-adjustable cross wrench, comprising:

• a primary bar, with an end being a socket insertion end and the other end being installed with an assistant turning handle, and a center portion being a thickening middle section having a penetrating hole, a compression knob installed adjacent to the penetrating hole and provided for a snapping purpose, and an inner threaded hole formed at the bottom of the thickening middle section for locking a positioning bold therein, and slightly extending a front edge of the positioning bold into the penetrating hole;
• and
• a torque-setting secondary bar, comprising a plugging inner rod with a spacer ring slot, a force applying outer rod with a torque-setting module installed therein, a handheld turning handle, an elastic pushing member, a torque-adjusting screw cap and a retaining ring, wherein a pivoting end of the plugging inner rod has a pin hole, and a positioning slot formed at the bottom of the plugging inner rod and configured to be corresponsive to the positioning bold for inserting and pivotally coupling an insert pin and the force applying outer rod with the pin hole;
• such that the aforementioned elements can be connected and combined with each other to form a cross wrench, and the torque-adjusting screw cap can be rotated to adjust and set the torque-setting module to a predetermined torque value, so as to achieve an expected torque-setting purpose.
