[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0020] As Figures 1-6As shown, to solve the problem that the brushes on existing long-handled grinding brush heads cannot be added, removed, or replaced, this utility model provides a long-handled grinding brush head with removable brushes, including a long rod 1. A first flat pad 4 and a second flat pad 9 are sequentially fitted onto the lower end of the long rod 1. A brush cluster 3 is fitted onto the long rod 1 between the first flat pad 4 and the second flat pad 9. Symmetrically arranged axially extending grooves 6 are provided on the outer side wall of the long rod 1. The upper end of the grooves 6 extends to the upper end face of the long rod 1. A pressing groove 7 extending circumferentially along the long rod 1 is provided on one side of the lower end of the grooves 6. The depth of the pressing groove 7... The angle gradually decreases from the slide groove 6 to the other end, and also includes a clamping sleeve 2, which is sleeved on the outside of the long rod 1. The inner hole of the clamping sleeve 2 is provided with a boss 21 that fits into the slide groove 6. The lower end of the clamping sleeve 2 is pressed against the second flat pad 9 and rotates in the direction of the extrusion groove 7, so that the boss 21 slides along the corresponding extrusion groove 7 and is interference-fitted with the bottom of the extrusion groove 7. By setting the cooperation between the extrusion groove 7 and the clamping sleeve 2, the clamping sleeve 2 can be disassembled at least twice, thereby increasing or decreasing the number of brush clusters 3 within a certain range, or replacing the brush clusters 3. The cooperation of the boss 21 is more stable and firm than the threaded connection.

[0021] Specifically, in use, the first flat pad 4 is first put onto the long rod 1, and then the brush cluster 3 is put onto the long rod 1. The thickness of the brush cluster 3 allows the height of the second flat pad 9 to reach the position of the extrusion groove 7. The addition or removal of the brush cluster 3 can adjust the second flat pad 9 within the range of the extrusion groove 7. Then, the clamping sleeve 2 is put on and slides down along the slide groove 6 until it contacts the second flat pad 9. Then, rotating the clamping sleeve 2 can fix the clamping sleeve 2 in the extrusion groove 7, thereby pressing and fixing the brush cluster 3.

[0022] Since the depth of the extrusion groove 7 gradually decreases from the slide groove 6 to the other end, the clamping sleeve 2 becomes tighter with the extrusion groove 7 as it rotates, and the tightness can be adjusted as needed.

[0023] To facilitate rotation of the clamping sleeve 2, the clamping sleeve 2 is in the form of a quadrilateral or hexagonal structure, making it convenient to use tools to rotate the clamping sleeve 2.

[0024] like Figure 2 As shown, the upper edge of the extrusion groove 7 forms a beveled step 8. When the clamping sleeve 2 rotates, the boss 21 contacts the beveled step 8 and pushes the clamping sleeve 2 to move axially downward. This can generate a downward thrust when the clamping sleeve 2 rotates, pressing the brush cluster 3 tightly and improving the polishing effect.

[0025] In the embodiment, the lower end edge of the inner hole of the clamping sleeve 2 is provided with a tapered portion 22, which facilitates the clamping sleeve 2 to be sleeved on the long rod 1. In addition, the lower end of the long rod 1 is axially provided with an inner recess 10, the edge of the inner recess 10 is outwardly folded to form a flange portion 5, and the first flat pad 4 is placed on the upper side of the flange portion 5, which facilitates the flanging of the side wall by the inner recess 10, and the first flat pad 4 does not need to be separately supported and fixed by using a fastener.

[0026] It should be noted that all directional indications, such as upper, lower, left, right, front, back, etc., in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.

[0027] In addition, the description such as "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0028] In the present application, unless otherwise specifically defined and limited, the terms "connection", "fixing" and the like should be understood in a broad sense, for example, "fixing" can be fixed connection, or detachable connection, or integral; can be mechanical connection, or electrical connection; can be directly connected, or indirectly connected through an intermediate medium; can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise specifically limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] In addition, the technical solutions of each embodiment of the present application can be combined with each other, but it must be based on the realization of the ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor is within the scope of protection required by the present application.
