Holding wrench

A holding wrench, comprising:

• a clamping assembly, comprising:
• a housing,
• a transmission gear received in the housing,
• a first latching member rotatably received in the housing,
• a second latching member rotatably received in the housing,
• an adjusting subassembly comprising:
• an adjusting member slidably mounted on the housing, the adjusting member defining a pair of latching grooves thereon;
• a pair of pushing members protruding from the adjusting member and located between the first latching member and the second latching member, and
• a pair of resilient members received in the housing and respectively resists the first latching member and the second latching member toward the transmission gear;
• and
• a pair of resisting members mounted on the housing and resisting the adjusting member;
• and
• a pair of handles respectively connected to opposite ends of the housing, wherein, when the adjusting member is moved toward the second latching member, one of the pair of pushing members pushes the second latching member to compress the corresponding resilient member and away from the transmission gear, and the other one of the pair of pushing members moves away from the first latching member to allow the first latching member engaging with the transmission gear, and the pair of resisting members latches into the pair of latching grooves, thereby positioning the adjusting member.
