The rear side of the toggler includes at least two connecting portions. At least two elastic elements are arranged between the connecting portions of the direction switch member and the toggler in order to provide an elastic force to push the toggler to abut against the locking member. The elongated toggler can be applied to a ratchet structure of a greater thickness in order to increase the structural strength and operational torque of the ratchet wrench. Furthermore, the elastic elements can provide a uniform elastic force in the length direction of the toggler, thereby allowing the locking member to engage with the ratchet structure properly.

The torque adjustment mechanism includes an abutting member, an adjustment member and an adjustment button. The abutting member has a first slope disposed at rear end of the abutting member in contact with a second slope disposed at a front end of the adjustment member. When adjusting the set torque value of the torque wrench, the adjustment button is rotated to drive the adjustment member to displace in a transverse direction of the tubular body. By means of the cooperation between the first and second slopes, the abutting member is displaced in a longitudinal direction of the tubular body to compress or release an elastic member positioned in front of the abutting member.
