1. A power tool combination, comprising:
a power tool comprising a housing comprising a substantially tubular first housing and a first grip for holding, wherein the first grip is formed on or connected to the first housing; and
an auxiliary handle comprising:
a second grip;
a clamping assembly connected to the second grip and comprising a first clamping arm and a second clamping arm that are disposed opposite to each other to clamp the first housing; and
a locking assembly having a locked state where a relative movement between the clamping assembly and the first housing is restrained and a released state where the first clamping arm and the second clamping arm are caused to move away from each other to allow the relative movement between the clamping assembly and the first housing,
wherein the locking assembly comprises an operation member, when a position state of the operation member is changed, the locking assembly is switched between the locked state and the released state, and, when the locking assembly is switched to the released state, the operation member applies a drive force to at least one of the first clamping arm and the second clamping arm so that the first clamping arm and the second clamping arm move away from each other, and
wherein the auxiliary handle further includes a connecting rod, the connecting rod including a smooth segment and a threaded segment, where the smooth segment is connected to the second grip, and the threaded segment is disposed at an end of the smooth segment facing away from the second grip.
