[0032] Example 1

[0033] Reference Figure 1-9 This embodiment provides a conveniently foldable and retractable paint tool brush, including a brush head assembly 100 and a connecting assembly 200, which solves the problem that the traditional paint tool brush is difficult to fit into a small-sized box packaging, cannot be folded and placed in the packaging box, and is difficult to install and adjust the length conveniently during use to adapt to more construction scenarios.

[0034] Specifically, the brush head assembly includes a brush head 101 and a mounting member 102, the connecting assembly 200 includes a first rod body 201, a second rod body 202, a rotating member 203 and an adjusting member 204, the first rod body 201 is movably connected to the mounting member 102, the second rod body 202 is movably connected to the first rod body 201 through the rotating member 203, and the adjusting member 204 is arranged on the side wall of the second rod body 202.

[0035] Furthermore, a mounting part 102 is provided to realize quick installation and disassembly between the brush head assembly 100 and the connecting assembly 200 when taking out the package. Through the adjusting part 204, the length of the brush handle can be freely adjusted within a certain range, so that the tool brush can adapt to a variety of construction scenarios, improving the flexibility and adaptability of construction. Through the rotating part 203, the tool brush can be folded when not in use, occupying smaller packaging space, thereby adapting to the future trend of automated box packaging in the paint industry and ensuring that the tool brush can be easily stored in a small package.

[0036] Example 2

[0037] Reference Figure 1-9 , this embodiment is based on the previous embodiment.

[0038] Specifically, the rotating member 203 includes a rotating base 203a, a control block 203b and a movable end 203c. The rotating base 203a is fixedly connected to one end of the first rod body 201, and the side wall of the control block 203b is connected to the side wall of the connecting shaft 203a-1 at one end of the rotating base 203a through the control spring 203b-1, so that the control block 203b can perform elastic movement along the connecting shaft 203a-1.

[0039] like Figure 4 As shown, the side wall of the control block 203b has a through cavity, and a plurality of locking protrusions 203b-2 are provided on one side of the cavity. The end of the connecting shaft 203a-1 also extends into this cavity, and the diameter of the end is slightly larger, so that the control block 203b cannot be separated from the connecting shaft 203a-1.

[0040] Furthermore, one end of the movable end 203c is fixedly connected to the second rod body 202, and the other end is inserted into the cavity of the control block 203b. The groove set on its side wall is fitted and connected with the locking protrusion 203b-2, and the end of the connecting shaft 203a-1 also maintains a movable connection with the connection between the control block 203b and the movable end 202c, so that the control block 203b and the movable end 203c can rotate around the center of the connecting shaft 203a-1.

[0041] During use, when the tool brush needs to be folded, the top of the pressing control block 203b is pressed, and the compression control spring 203b-1 is deformed, so that the movable end 203c is disengaged from the locking protrusion 203b-2, and the second rod body 202 fixedly connected to the movable end 203c can be freely rotated.

[0042] It should be noted that when the control spring 203b-1 is not subjected to force, the movable end 203c is always engaged with the control block 203b via the locking protrusion 203b-2.

[0043] Furthermore, a handle 202a is provided on the outside of the second rod body 202, and the second rod body 202 is movably connected to the handle 202a. The second rod body 202 can perform telescopic movement within the handle 202a, but is still in a connected state with the handle 202a at the longest length. The side wall of the handle 202a is provided with a groove, and a plurality of adjustment teeth 202a-1 are provided in the groove to realize the telescopic adjustment of the second rod body 202.

[0044] Specifically, the adjusting member 204 includes a pressing block 204a and an adjusting block 204b. The pressing block 204a is connected to the groove on the side wall of the second rod body 202 through a pressing spring 204a-1. When the pressing block 204a is subjected to force, the pressing spring 204a-1 is compressed, so that the length of the pressing block 204a extending out of the groove becomes shorter.

[0045] Furthermore, the adjustment block 204b is disposed on the side wall of the pressing block 204a and is fixedly connected to the pressing block 204a. The adjustment protrusion 204b-1 on the side wall of the adjustment block 204b fits with the adjustment tooth 202a-1 to achieve a snap connection. An auxiliary block 204a-2 is disposed at one end of the pressing block 204a. The auxiliary block 204a-2 is bent and disposed outside the slot of the handle 202a.

[0046] During use, if the length of the tool brush needs to be extended, the operator only needs to press the auxiliary block 204a-2 to disengage the adjustment protrusion 204b-1 from the adjustment tooth 202a-1, and then push the bent auxiliary block 204a-2 to push the second rod body 202 upward to achieve an extension effect to a certain length.

[0047] It should be noted that when the pressing spring 204 a - 1 is not subjected to force, the adjusting protrusion 204 b - 1 is always engaged with the adjusting tooth 202 a - 1 .

[0048] Furthermore, the mounting member 102 includes a connecting block 102a and a limiting ball 102b. The connecting block 102a is fixedly connected to the side wall of the brush head 101. The limiting ball is arranged in a groove on the side wall of the connecting block 102a and is connected to the connecting block 102a through a limiting spring. The mounting member 102 is movably connected to a connecting sleeve 201a arranged at one end of the first rod body 201. A rotating groove is provided on the inner side wall of the connecting sleeve 201a. The limiting ball 102b is movably connected to the rotating groove. When rolling the paint, the brush head 101 can also roll smoothly.

[0049] When the tool brush needs to be installed, it is only necessary to insert the first rod body 201 equipped with one end of the connecting sleeve 201a into the connecting block 102a, so that the inner side wall of the connecting sleeve 201a squeezes the limiting ball 102b to complete the sleeve connection, so that the limiting ball 102b is in the rotating groove 201a-1, which neither affects the rolling of the brush head 101 during use nor will it be easily detached. When disassembling, it is only necessary to hold the connecting sleeve 201a and pull it in the opposite direction to achieve disassembly.

[0050] In summary, the mounting member 102 enables convenient installation and disassembly, the rotating member 203 enables the handle structure to be folded and placed when not in use or when packaged, saving packaging space and being able to be easily unfolded and used without the need for cumbersome assembly, and the adjusting member 204 enables adjustment within a certain length, making it suitable for use when the height is insufficient during construction.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
