The bottom of the left trapezoidal block 2 and the bottom of the right trapezoidal block 3 are provided with a trapezoidal groove 11. When the left trapezoidal block 2 contacts the right trapezoidal block 3, the trapezoidal grooves 11 on the left trapezoidal block 2 and the right trapezoidal block 3 can be combined into a regular hexagon. At this time, the two trapezoidal grooves 11 enable the guide sleeve to rotate the bolt or nut. The bottom of the left trapezoidal block 2 and the bottom of the right trapezoidal block 3 are provided with a sliding groove 12, and the inner wall of the sliding groove 12 is fixedly connected to a limiting block 13. The bolt or nut entering the trapezoidal groove 11 is guided by the sliding groove 12, and the bolt or nut entering the trapezoidal groove 11 is limited by the limiting block 13.

A stop block 24 is fixedly connected to the upper surface of the column 22. Through the cooperation of the stop block 24 and the push block 23, the column 22 cannot be separated from the third sliding hole 21.

[0037] In the utility model, when the user uses the guide sleeve, the user first rotates the rotating block 83 to gradually reduce the distance between the front and rear vertical plates 91 under the cooperation of the first stud 81, the second stud 82 and the threaded hole 92. When the pressing block 93 presses the left trapezoidal block 2 and the right trapezoidal block 3, the rotation of the rotating block 83 is stopped, and the left trapezoidal block 2 and the right trapezoidal block 3 can be closely contacted by the pressing block 93, and the guide sleeve can screw the bolt or nut through the trapezoidal groove 11. When the bolt or nut is stuck in the trapezoidal groove 11, the distance between the front and rear vertical plates 91 is gradually increased by rotating the rotating block 83 under the cooperation of the first stud 81, the second stud 82 and the threaded hole 92. When the pressing block 93 loosens the left trapezoidal block 2 and the right trapezoidal block 3, the left trapezoidal block 2 and the right trapezoidal block 3 can be directly separated. At this time, the bolt or nut stuck in the guide sleeve is loosened, and the bolt or nut can be taken out from the trapezoidal groove 11.
