[0028] Two inner locking heads 2-2 are symmetrically arranged on the inner side of the locking sleeve 2, and the distance between the two inner locking heads 2-2 is greater than the diameter of the connecting piece 3. Two outer locking heads 3-3 are symmetrically arranged on the outer side of the connecting piece 3, and the outer locking heads 3-3 are located below the inner locking heads 2-2. The outer side of the locking sleeve 2 is provided with anti-slip grooves 2-1;

[0029] An alignment inclined plate 3-2 is provided on the connecting member 3 below the outer locking head 3-3, the top of the alignment inclined plate 3-2 is connected to the bottom of the outer locking head 3-3, and two alignment grooves 1-4 are symmetrically provided on the inner top of the handle 1, and each alignment inclined plate 3-2 is movably inserted into the alignment groove 1-4;

[0030] A limiting plate 3 - 4 is provided on the outer side of the connecting member 3 , and the limiting plate 3 - 4 is located above the inner locking head 2 - 2 .

[0031] The principle and use process of this utility model:

[0032] During installation, firstly connect the locking sleeve 2 to the handle 1 through threads and screw it into place, then screw on the connecting bolt 4, at which time the head of the connecting bolt 4 is located at the end in the oblique slot 1-5, then rotate the locking sleeve 2 so that the head of the connecting bolt 4 reaches the other end in the oblique slot 1-5, then align the connecting piece 3 with the handle 1 so that the outer locking head 3-3 and the inner locking head 2-2 are staggered, and at the same time, the alignment inclined plate 3-2 is aligned with the alignment slot 1-4, and the connecting piece 3 is inserted downward into the connecting slot 1-1 of the handle 1, and the anti-rotation insert strip 1-2 is inserted into the anti-rotation slot 3-1. The alignment inclined plate 3-2 enters the alignment groove 1-4, and the outer locking head 3-3 reaches the bottom of the inner locking head 2-2, that is, it is inserted and installed in place. The connection between the anti-rotation insert strip 1-2 and the anti-rotation slot 3-1, and the alignment inclined plate 3-2 and the alignment groove 1-4 respectively fixes the connecting member 3 and the handle 1 in the axial direction to prevent axial rotation between each other, and then tightens the locking sleeve 2, and the inner locking head 2-2 reaches the top of the outer locking head 3-3 to limit the connecting member 3, and tightens the connecting bolt 4 at the same time, so that the connecting bolt 4 is against the inclined slot 1-5, thereby fixing the locking sleeve 2 and the handle 1;

[0033] When replacement is needed, it is only necessary to loosen the connecting bolt 4 and rotate the locking sleeve 2 so that the head of the connecting bolt 4 moves to the upper end of the oblique slot 1-5. At this time, the inner locking head 2-2 and the outer locking head 3-3 are offset, and the connecting piece 3 can be pulled out and replaced with a new handle and locking sleeve 2 or a new connecting piece 3 and tool can be replaced on the handle 1.
