In the locked connection, the brush block 2 is substantially parallel to the bottom end surface of the brush shaft 1.

As shown in fig. 2-5, specifically, the bottom of the lower brush handle 1a is provided with an insertion groove 11, the top of the brush block 2 is provided with an insertion connector 21, and the locking connection structure includes an elastic clamping pin 111 disposed on a wall of the insertion groove 11 and a clamping groove 211 disposed on the insertion connector 21. In the locked connection state, the elastic clamping leg 111 has an inward contraction tendency and is clamped into the clamping groove 211. The elastic clamping legs 111 are arranged in a plurality of numbers and are evenly arranged along the circumferential direction of the brush holder 1 at intervals, and the clamping grooves 211 are annular. The number of the elastic clamping legs 111 in this embodiment is 2, and the elastic clamping legs are symmetrically arranged on two sides of the brush handle 1.

As shown in fig. 2-5, the pushing frame 3 is a sliding sleeve partially covering the brush handle 1, the pushing frame 3 can slide along the axial direction, and the pushing button 32 is disposed on the pushing frame 3. The inner wall of the pushing frame 3 is provided with a squeezing block 31 positioned in the inserting groove 11, and the squeezing block 31 can expand the elastic clamping leg 111 when the pushing frame 3 moves downwards in the axial direction to enable the elastic clamping leg 111 to be separated from the clamping groove 21, so that locking connection is released. The pushing part 35 capable of pushing the brush block 2 is formed at the bottom of the pushing frame 3, and in a state that the locking connection is released, the pushing part 35 of the pushing frame 3 can push the brush block 2 downwards, so that the plug-in connector 21 is separated from the plug-in groove 11, and the brush block 2 is separated from the brush handle 1.

As shown in fig. 2-3, a guiding sliding structure is arranged between the pushing frame 3 and the brush handle 1. The guiding sliding structure comprises a guiding rib 33 arranged on the inner wall of the pushing frame 3 and a guiding groove 12 arranged on the outer wall of the lower brush holder 1 a. In other embodiments, the guiding rib 33 is disposed on the outer wall of the lower handle 1a, and the guiding groove 12 is disposed on the inner wall of the pushing frame 3. The quantity of guide slot 12 is a plurality of, and the interval locates brush holder 1 circumference and axial, and the quantity of direction muscle 33 is a plurality of, and direction muscle 33 and guide slot 12 one-to-one setting.

As shown in fig. 2-3, the inner wall of the pushing frame 3 is also provided with a positioning rib 34, and the outer wall of the lower brush handle 1a is provided with a positioning groove 13; in the locked connection state, the positioning rib 34 is provided in the positioning groove 13. In other embodiments, the positioning rib 34 may be disposed on the outer wall of the lower brush handle 1a, and the positioning groove 13 may be disposed on the inner wall of the pushing frame 3. Because the push frame 3 moves downwards along the axial direction of the brush holder 1 to realize the release of the locking connection and the complete separation of the brush block 2 and the brush holder 1, the inner wall of the push frame 3 is also provided with the abdicating groove 14 positioned below the positioning groove 13, so that the positioning rib 34 moves downwards in the abdicating groove 14 in the axial direction.
