The outer cylinder 10 is provided with a plurality of pairs of first hexagonal holes 11 and first round holes 12, and preferably, the outer cylinder is provided with two pairs of first hexagonal holes 11 and first round holes 12. In any pair of the first hexagonal hole and the first round hole, the side length of the first hexagonal hole is equal to the radius of the first round hole, the first hexagonal hole is communicated with the first round hole, a first angle of the first hexagonal hole is overlapped with the circle center of the first round hole, a second angle of the first hexagonal hole is opposite to the first angle, and the distance between the second angle and the circle center of the first round hole is equal to twice of any side length of the first hexagonal hole. Any pair of the first hexagonal hole and the first round hole is distributed along the circumferential direction of the outer cylinder; any pair of the first hexagonal holes is communicated with the first round hole. A plurality of pairs of first hexagonal holes 11 and first round holes 12 are different in size and are distributed along the axial direction of the outer barrel so as to be matched with wrenches different in size.

The radius of the first round hole 12 is equal to the radius of the second round hole 21, the outer cylinder 10 and the inner cylinder 20 rotate relatively, and the first round hole can coincide with the second round hole, namely, an extension line of a connecting line of the circle center of the first round hole and the second round hole passes through the central line of the inner cylinder. When the wrench is inserted into the handle, the first round hole needs to be overlapped with the second round hole. The first round hole and the second round hole which are equal in size can enable a wrench inserted into the first round hole and the second round hole to be stable.

The size of the second hexagonal hole 32 is equal to that of the first hexagonal hole 11, and the size of the second hexagonal hole and the size of the first hexagonal hole are equal to that of the wrench. The outer cylinder 10 and the middle cylinder 30 rotate relatively, and the second hexagonal hole can coincide with the first hexagonal hole, namely, the second hexagonal hole and the first hexagonal hole form a hexagonal hole to be matched with a hexagonal wrench. The width of the strip-shaped groove is larger than or equal to the distance between any two parallel edges of the second hexagonal hole, when the outer barrel and the middle barrel rotate relatively, the wrench moves relatively along the strip-shaped groove, and the strip-shaped groove plays a role in guiding the wrench to be accurately clamped into the first hexagonal hole and the second hexagonal hole. The strip-shaped groove and the second hexagonal hole are arranged along the circumferential direction of the middle cylinder.

The left end of the inner cylinder 20 is pivoted with the left end of the outer cylinder 10 through a first bearing, the right end of the inner cylinder is separated from the right end of the outer cylinder, conditions are provided for the middle cylinder to be matched between the outer cylinder and the inner cylinder, the left end of the inner cylinder protrudes out of the left end of the outer cylinder, and an operator rotates the inner cylinder through the left end of the inner cylinder; the right end of the middle tube 30 is pivotally connected to the right end of the outer tube by a second bearing so that the inner tube and the middle tube can rotate independently of each other relative to the outer tube.

The right end of the middle barrel 30 is provided with a triangular rod 40, the outer side wall of the right end of the outer barrel 10 is provided with an external thread, an internal thread piece 50 is in threaded connection, the right end of the internal thread piece is provided with a triangular hole 51, and the triangular hole is matched with the triangular rod. The internal thread piece is rotated, the internal thread piece rotates and moves axially, the internal thread piece moves axially relative to the triangular rod, the rotating motion of the internal thread piece is transmitted to the triangular rod, and the triangular rod rotates to drive the middle cylinder to rotate. Because the meshing of internal and external screw thread has certain self-locking action, consequently, the setting of internal thread spare can avoid the spanner to react in second hexagonal hole and make the well section of thick bamboo take place to rotate.

In practical operation, the outer cylinder 10 is stationary, the middle cylinder 30 is rotated, the strip-shaped grooves 31 are aligned with the first circular holes 12 in and out, and the inner cylinder 20 is rotated, and the second circular holes 21 are aligned with the first circular holes 12 in and out. The first round hole, the bar-shaped groove and the second round hole are radially inserted into the hexagonal wrench along the handle. Then, the outer cylinder and the middle cylinder are kept still, the wrench is rotated by taking the central line of the inner cylinder as a rotating shaft, the wrench moves in the strip-shaped groove 31, the wrench drives the inner cylinder 20 to rotate, and the wrench is clamped into the first hexagonal hole 11 of the outer cylinder 10. Then, the internal thread member 50 is rotated, the middle barrel 30 is rotated, and the wrench moves relatively along the strip-shaped groove 31 until the second hexagonal hole 32 is matched with the wrench, and the first hexagonal hole and the second hexagonal hole form a complete hexagonal hole to be matched with the hexagonal wrench. So far, the wrench can be used.
