[0025] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0026] like Figure 1 - Figure 5 As shown, a combined grinding brush includes a rectangular housing 1. A semi-open end cap 2 is provided at the upper end of the rectangular housing 1. A limit bearing 3 is provided at the upper end of the semi-open end cap 2. A drive shaft 4 is rotatably arranged inside the limit bearing 3. A rocker arm 5 is fixedly connected to the upper end of the drive shaft 4. A crank handle 6 is fixedly connected to the end of the rocker arm 5 away from the drive shaft 4. A grinding brush 7 is hung at the lower end of the drive shaft 4.

[0027] The rectangular shell 1 has a mounting groove in the middle of its upper end, and a dustproof dish 11 is placed in the mounting groove. The bottom of the dustproof dish 11 is hollow and the inner wall of the dish is evenly provided with baffles 12 near the lower end. The baffles 12 are made of rubber material.

[0028] The rectangular shell 1 has a rectangular groove at the lower end of its side wall. A dust collection box 13 is slidably installed in the rectangular groove. A spherical pull head 14 is fixedly installed on the upper end of the dust collection box 13, which is open and located away from the rectangular groove.

[0029] The dust collection box 13 has a limiting groove 131 in the middle of the side wall of the rectangular slide groove. An arc-shaped card 132 is provided in the limiting groove 131. One end of the arc-shaped card 132 is fixed in the limiting groove 131, and the other end slides and fits in the limiting groove 131. The arc-shaped card 132 is made of copper or stainless steel.

[0030] The semi-open end cap 2 consists of a fixed end cap 21 and a hinged end cap 22. One end of the hinged end cap 22 is hinged to the upper end of the rectangular shell 1 by a pin, and the other end is fixedly connected to a lug 23.

[0031] The drive shaft 4 is symmetrically provided with hooks 8 at its lower end. The upper "hook"-shaped end of the hook 8 is made of elastic rubber. A rubber rod 9 is snapped into the hook 8. The two ends of the rubber rod 9 are fixedly connected to the clamping plate 10. The lower end of the clamping plate 10 is hinged to the brush handle of the grinding brush 7 by a pin. The clamping plate 10 has a horizontal "J" shaped structure and is made of elastic plastic.

[0032] Working principle: The opening and closing of the hinged end cap 22 can be achieved by manually turning the lever 23. When grinding is required, first open the hinged end cap 22, and then pull the "hook"-shaped end of the hook 8 upward. At this time, the rubber rod 9 will disengage from the hook 8. Then, remove the plate 10 together with the rubber rod 9. At this time, the grinding brush 7 can be taken out by holding the handle of the brush for grinding.

[0033] After grinding, manually pull the hook-shaped end of the upper part of the hook 8 upwards again. At this time, the hook-shaped end will deform upwards. At the same time, place the rubber rod 9 inside the hook 8 and release the hook-shaped end. At this time, the reset action of the hook-shaped end can firmly lock the rubber rod 9 inside the hook 8. The lower part of the grinding brush 7 will contact the stop bar 12. Then close the openable end cover 22 to make the upper part of the grinding brush 7 sealed. Manually hold the crank handle 6 to drive the rocker arm 5 and drive shaft 4 to rotate, thereby driving the locked grinding brush 7 to rotate. During this process, the bristles of the grinding brush 7 will vibrate continuously under the action of the stop bar 12. The grinding debris inside the bristles will fall downwards into the dust collection box 13. Since the upper part of the grinding brush 7 is sealed, the grinding debris will not overflow from the semi-open end cover 2.

[0034] After a period of time, stop rotating the grinding brush 7, manually pull the dust collection box 13 outward by holding the ball-shaped pull head 14, clean the grinding debris inside, and then reset the dust collection box 13. During the reset process, the arc-shaped card 132 will be compressed and extended into the limiting slide groove 131 under the action of the side wall of the rectangular shell 1. Due to the elasticity of the arc-shaped card 132, the arc-shaped card 132 will abut against the inner wall of the rectangular shell 1, thereby improving the stability of the dust collection box 13 during the working process and preventing the dust collection box 13 from sliding out of the rectangular slide groove and causing the grinding debris to overflow during the cleaning of grinding debris by the grinding brush 7.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
