[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] like Figure 1As shown, this adjustable tube brush includes a pistol drill 1, a brush body 2, a transmission component 3, a bracket 4, and a holding part 5. The brush body 2 is connected to the pistol drill 1 via the transmission component 3. The brush body 2 receives the rotational force of the pistol drill 1 through the transmission component 3 and rotates, allowing the brush body 2 to rotate and fully contact the inner wall of the tube during cleaning, thereby quickly removing stains from the inner wall of the tube. To avoid holding the pistol drill 1 and manipulating the movement of the brush body 2, the holding part 5 located between the brush body 2 and the transmission component 3 is used to control the brush body 2. This greatly reduces the weight required to control the brush body 2 and avoids arm pain caused by holding the pistol drill 1 for a long time while the brush body 2 cleans the tube. Based on this, the pistol drill 1 is fixed to one side of the cleaning tank by the bracket 4, allowing the pistol drill 1 to stably transmit rotational force to the brush body 2 through the transmission component 3.

[0039] like Figure 2 As shown, and for reference Figure 1 The pistol drill 1 includes a gun body 11, a clamping head 12 located at one end of the gun body 11, a motor 13 fixed inside the gun body 11 and coaxially connected to the retractable moving part of the clamping head 12, a battery 14 detachable at the bottom end of the gun body 11 and electrically connected to the motor 13, and a first push-button switch 15 retractable at the inner angle of the gun body 11 and electrically connected to the motor 13.

[0040] By holding the gun body 11 and pressing the first button switch 15, the motor 13 is started to rotate. The rotational force output by the motor 13 is transmitted to the brush body 2 through the transmission component 3. As a result, the brush body 2 rotates with the rotation of the motor 13. The rotating brush body 2 is moved into the tube cavity by the handle 5 to clean the stains on the inner wall of the tube cavity. Moreover, the rotating brush body 2 does not require the cleaning personnel to repeatedly operate the brush body 2 to move back and forth in the tube cavity. The stains in the tube cavity can be efficiently removed simply by changing the contact position between the brush body 2 and the tube cavity by the handle 5i.

[0041] like Figure 3 As shown, and for reference Figure 1 and Figure 2 The bracket 4 consists of a snap-fit ​​part 41 detachably connected to the pistol drill 1 and a limiting part 42 located on the snap-fit ​​part 41. The limiting part 42 is used to connect to, for example, the side of the countertop near the cleaning pool, and is fixedly connected to the side of the countertop by clamping. As the bracket 4 is fixed, the pistol drill 1 is also fixed under the connection of the bracket 4 to stand in the position near the cleaning pool, thereby stably providing rotational force to the brush body 2 through the transmission member 3.

[0042] Furthermore, the locking part 41 consists of a first base 411 and a sleeve 412 fixed on the first base 411 and elastically locked to the outside of the gun body 11. The inside of the sleeve 412 matches the shape of the grippable part of the gun body 11, and an opening close to its own width is provided on one side of the sleeve 412. When connecting, the pistol drill 1 is squeezed by the whole, causing the opening to expand elastically. At this time, the grippable part of the gun body 11 enters the inside of the sleeve 412. Then the opening elastically contracts, allowing the sleeve 412 to wrap around the gun body 11. The battery 14 at the bottom of the gun body 11 abuts against the first base 411, so that the pistol drill 1 is fixed immovably between the first base 411 and the sleeve 412 in the up, down, left and right directions. When disengaging, the pistol drill 1 is pulled forcefully along the opening direction of the sleeve 412, causing the opening of the sleeve 412 to expand elastically, so that the pistol drill 1 can be removed from between the first base 411 and the sleeve 412.

[0043] The limiting part 42 consists of a second base 421 fixed at the bottom of the first base 411 and a stop member 43 located on the second base 421. A space is formed between the second base 421 and the first base 411 that can be placed on the side of the table. When the side of the table is placed between the second base 421 and the first base 411, the stop member 43 moves vertically upward and is clamped between the stop member 43 and the bottom of the first base 411, so that the bracket 4 is fixed on the side of the table.

[0044] In some embodiments, such as Figure 4 As shown, and for reference Figure 3 The stopper 43 consists of a bolt body 431 threaded vertically to the second base 421 and a clamping plate 432 rotatably connected to the top of the bolt body 431. Specifically, a threaded hole is vertically opened in the middle of the second base 421, and the bolt body 431 is threaded into the threaded hole. As the bolt body 431 rotates in the threaded hole, the threaded connection position between the bolt body 431 and the threaded hole changes. At this time, the height of the bolt body 431 protruding above the threaded hole gradually increases or decreases. For example, when it gradually increases, it drives the clamping plate 432 at the top of the bolt body 431 to move upward until it abuts against the bottom of the side of the table, thereby limiting the side of the table between the first base 411 and the clamping plate 432.

[0045] like Figure 5 As shown, and for reference Figure 1The brush body 2 consists of a first shaft 21 and a bristle part 22 integrally connected to one end of the first shaft 21; the transmission component 3 consists of multiple second shafts 31 and multiple universal joints 32, the multiple universal joints 32 being used to connect the multiple second shafts 31 into one unit; based on this, the second shaft 31 located at one end is detachably connected to the clamping head 12. The specific structure of the clamping head 12 is as described in the structure of connecting the drill bit in the existing pistol drill 1. For example, by rotating the rotatable part of the clamping head 12, the rotating part moves axially and, under the action of the inclined screw post group, presses or does not press the retractable part. When pressed, the retractable part retracts inward to clamp the second shaft 31. Subsequently, the retractable part drives the second shaft 31 to rotate under the drive of the motor 13.

[0046] The second shaft 31 located at the other end is detachably connected to the first shaft 21 of the brush body 2, thereby allowing the brush body 2 to receive the rotational force output by the pistol drill 1 through the transmission component 3. Furthermore, under the action of the universal joint 32, the second shaft 31 and adjacent second shafts 31 can rotate around the axis of the universal joint 32, including but not limited to... Figure 1 The rotation state of the brush body 2 facilitates the adjustment of the cleaning angle of the brush body 2 and the position of the bristle part 22 in the tube or other object to be cleaned;

[0047] The grip 5 consists of a bearing 51 sleeved on the second shaft 31 at the other end, a handle 52 fixed on the bearing 51 and extending to one side, and a second button switch 53 that can be telescopically moved on the handle 52 and is connected to the motor 13 for signal control. It should be noted that the second button switch 53 is a wireless switch. Based on this, a receiving module for receiving wireless switch signals is integrated in the gun body 11. The receiving module is electrically connected to the motor 13. The wireless switch press box transmits signals to the receiving module. After receiving the signals, the receiving module controls the motor 13 to work. Thus, when the handle 52 is gripped, the second button switch 53 is activated, which allows the brush body 2 to rotate on the bearing 51. The position of the brush body 2 can be changed by gripping the handle 52.

[0048] Furthermore, a plurality of protrusions 6 are fixed equidistantly on the circumference of the end of the first shaft 21 away from the bristle part 22; a sleeve 7 is fixed on the second shaft 31 at the other end, and a keyway 8 is provided in the sleeve 7 to accommodate the plurality of protrusions 6. By inserting the second shaft 31 with protrusions 6 into the sleeve 7, the brush body 2 can be connected as a whole to the transmission member 3 located on the shaft seat 51. A thin damping layer is provided on the inner wall of the sleeve 7, so that the second shaft 31 inserted into the sleeve 7 is not easy to come out. However, when disassembling, a slight force is applied to the second shaft 31 to make the second shaft 31 come out from the sleeve 7, so that the brush body 2 can be disassembled from the transmission member 3.

[0049] It should be noted that in some embodiments, a rubber sleeve is provided on the transmission component 3. The rubber sleeve covers the second shaft 31 and the universal joint 32 to prevent them from leaking out and to prevent them from contacting the second shaft 31 and the universal joint 32 in the rotating state. The rubber sleeve can twist and bend with the rotation of the universal joint 32.

[0050] In another embodiment, only a pistol drill 1 and a brush body 2 are included. The structure of the pistol drill 1 and the brush body 2 can be the same as in the previous embodiment. The difference is that the first shaft 21 in the brush body 2 is directly connected to the clamping head 12 of the pistol drill 1, so that the motor 13 directly drives the brush body 2 to rotate, thereby controlling the pistol drill 1 to control the angle of the brush body 2 and its position in the cavity.

[0051] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
