    Abstract: A holding wrench includes a clamping assembly and a pair of handles. The clamping assembly includes a housing, a transmission gear, a first latching member, a second latching member, and an adjusting subassembly. The first latching member and the second latching member engage with the transmission gear. The adjusting subassembly includes an adjusting member, a pair of pushing members protruding from the adjusting member, and a pair of resisting members. The adjusting member defines a pair of latching grooves. The pair of pushing members is located between the first latching member and the second latching member. When the adjusting member is moved toward the second latching member, one of the pair of pushing member pushes the second latching member away from the transmission gear, and the pair of resisting members latches into the pair of latching grooves, thereby positioning the adjusting member.
