[0009] The steel wire brush is correspondingly inserted into the mounting holes of the base plate and the ends of the multiple groups of widened plates, and the ends of the steel wire brush are in the shape of arc claws.

[0010] As a further solution of the present invention, a U-shaped buckle is provided at one end of the inner rod handle away from the outer rod handle, and the U-shaped buckle is clamped and fixed to a positioning hole on one side of the base plate.

[0011] As a further solution of the present invention, the first fixing member includes multiple groups of anchor bolts, and the base plate and the end of the inner rod handle are provided with mounting holes for mounting the ends of the anchor bolts.

[0012] As a further solution of the present invention, the second fixing member includes a lengthened bolt, and mounting holes for installing the lengthened bolt are correspondingly provided on the side surface of the base plate and the widened plate.

[0013] As a further solution of the present invention, the connecting assembly includes a locking ring base and a locking ring. The locking ring base is fixedly installed on the end of the outer rod handle, and the inner rod handle is slidably inserted into the locking mouth of the locking ring base. The locking ring is threadedly connected to the outside of the locking ring base.

[0014] As a further solution of the present invention, a placement cavity is provided at an end surface of the outer handle away from the inner handle, and the placement cavity is used to place the slag removal brazing rod. The opening of the placement cavity is sealed by a sealing plug.

[0015] Compared with the prior art, the utility model designs a handle assembly, a base plate, a widening plate and a wire brush. When the operator is in use, the length of the handle assembly and the number of widening plates can be flexibly adjusted according to the actual usage scenario. At the same time, by designing a wire brush to replace the existing steel nails, the quality of pulling and brushing is greatly improved, and the problem that the existing brushes used for brushing and pulling are often steel nails fixed on the wooden board, which can easily brush off concrete aggregate and gravel during use and the steel nails are easy to fall off, and the handle length cannot be adjusted, and the width of the wooden board cannot be adjusted according to the usage scenario, resulting in poor convenience of use.

[0018] The technical solution of the present utility model will be further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1 As shown, in an embodiment of the present utility model, a concrete joint brush device includes a handle assembly, including an outer rod handle 1 and an inner rod handle 2, wherein the outer rod handle 1 is slidably connected to the inner rod handle 2, and a connecting assembly is fixed and locked at the connection; a base plate 7 is fixedly connected to one end of the inner rod handle 2 through a first fixing member; a widening plate 9 is detachably mounted on both sides of the base plate 7 through a second fixing member; a steel wire brush 11 is correspondingly inserted into the mounting holes at the ends of the base plate 7 and the multiple groups of widening plates 9, and the end of the steel wire brush 11 is an arc-shaped claw;

[0020] Specifically, in the present invention, the wire brush 11 is made of thinner steel wire and is made into an arc shape after heat treatment, and one end is squeezed into the inside of the base plate 7. At the same time, the width specification of the widening plate 9 is relatively narrow. The user can adjust the number of widening plates 9 on both sides of the base plate 7 according to different actual usage scenarios.

[0021] like Figure 1 As shown, in the embodiment of the present utility model, the inner rod handle 2 is provided with a U-shaped buckle at one end away from the outer rod handle 1, and the U-shaped buckle is clamped and fixed with a positioning hole on one side of the base plate 7;

[0022] At the same time, the first fixing part includes multiple groups of anchor bolts 8, and the base plate 7 and the end of the inner rod handle 2 are provided with mounting holes for installing the ends of the anchor bolts 8. The utility model realizes the fixed connection between the base plate 7 and the inner rod handle 2 through the cooperation of U-shaped clips and multiple groups of anchor bolts 8.

[0023] like Figure 1 As shown, in the embodiment of the present utility model, the second fixing member includes a lengthened bolt 10, and mounting holes for installing the lengthened bolt 10 are correspondingly provided on the side surface of the base plate 7 and the widening plate 9. The lengthened bolt 10 passes through the mounting hole of the widening block and is locked in the mounting hole of the base plate 7, fixing the widening block and the base to form a whole;

[0024] At the same time, the mounting holes on the widening block are arranged in a staggered manner, which can not only anchor itself, but also serve as a base when adding a wide plate 9, thereby realizing the sequential installation of adjacent widening plates 9.

[0025] like Figure 1 As shown, in the embodiment of the present utility model, the connecting assembly includes a locking ring base 3 and a locking ring 4. The locking ring base 3 is fixedly mounted on the end of the outer rod handle 1, and the inner rod handle 2 is slidably inserted into the locking opening of the locking ring base 3. The locking ring 4 is threadedly connected to the outer side of the locking ring base 3. The utility model realizes the tightening or loosening of the locking base on the inner rod handle 2 by rotating the locking ring 4.

[0026] Of course, in actual design, the connecting assembly can also be replaced by other components with fixing capabilities, such as threaded clamping bolts for fixing.

[0027] like Figure 1 As shown, in the embodiment of the present utility model, a placement cavity is provided at the end face of the outer rod handle away from the inner rod handle 2, and the placement cavity is used to place the slag removal pick 5. The opening of the placement cavity is sealed by a sealing plug 6. When local fine aggregates adhere to the wire brush 11 during the brushing process, the slag removal pick 5 can be removed by knocking the wire brush 11.

[0028] To sum up the above, the utility model designs a handle assembly, a base plate 7, a widening plate 9 and a wire brush 11. When the operator is in use, the length of the handle assembly and the number of widening plates 9 can be flexibly adjusted according to the actual usage scenario. At the same time, by designing the wire brush 11 to replace the existing steel nails, the quality of pulling and brushing is greatly improved, and the problem that the existing brushes used for brushing and pulling are often steel nails fixed on the wooden board, which can easily brush off concrete aggregate and gravel during use and the steel nails are easy to fall off, and the handle length cannot be adjusted, and the width of the wooden board cannot be adjusted according to the usage scenario, resulting in poor convenience of use.

[0029] In the description of the present invention, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0030] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
