[0002] The typical structure of a paint roller brush is that a roller brush is installed on the roller brush shaft of a roller brush holder. The roller brush rotates on the roller brush shaft, and the roller brush holder protrudes from the end of the roller brush. When such a roller brush is used to brush the formwork release agent, it is not convenient to brush the corners of the formwork. Although there is also a roller brush holder structure with one end retracted into the roller brush, such as the Chinese utility model patent (application number 2023214511011), which adopts a zigzag roller brush holder, such a roller brush holder can only brush the corners of the formwork at one end. During the brushing process of some groove formworks with a width only slightly larger than the width of the roller brush, it is still inconvenient to repeatedly turn the roller brush. Moreover, currently, the roller brushes are generally of a straight cylinder structure and cannot be bent. When there are some small arc surfaces on the brushing surface of the formwork, the brushing efficiency is not high. In addition, the construction operation of brushing the formwork release agent is often carried out in a dim environment, which is not conducive to observing the brushing effect and operation.

[0029] The roller brush arm 10 is a roller brush arm bent from a steel plate strip. The roller brush arm is bent into two mutually perpendicular strip-shaped plates. One end of the two roller brush arms is hinged to the roller brush seat 40 through a pin shaft 41. The other end of the roller brush arm is provided with a roller brush shaft hole 11. The two roller brush arms 10 expand outward from the roller brush seat 40 and are connected to the roller brush shaft 20.

[0030] Both ends of the roller brush shaft 20 are provided with end shafts 21. The root of the end shaft 21 is provided with a shaft shoulder 22. The end shaft 21 passes through the roller brush shaft hole 11 from the inner side of the two roller brush arms. The end shaft 21 extends out of the roller brush arm 10. The shaft shoulder 22 corresponds to the roller brush arm 10 on the inner side, which can prevent the axial movement of the roller brush shaft.

[0031] One end roller brush 3a is respectively provided on the two end shafts 21. The two end roller brushes 3a extend out of the roller brush arm 10 at both ends of the roller brush arm. The end roller brush 3a rotates on the end shaft 21. The end roller brush 3a is provided with an end roller brush shaft hole 31. The end roller brush shaft hole 31 is rotationally matched with the end shaft 21. A retaining piece 24 fixed by a fastening screw 23 is provided at the end of the end shaft. The retaining piece 24 prevents the end roller brush 3a from coming off the end shaft 21. The end roller brush is provided with a counterbore 32, and the fastening screw 23 sinks into the counterbore 32, so that the end roller brush can better approach the corner of the template.

[0032] A plurality of roller brush segments 3b are installed on the roller brush shaft on the inner side of the two roller brush arms. The roller brush segments 3b rotate on the roller brush shaft.

[0033] The template release agent brushing tool in this embodiment uses end rollers that protrude from both ends of the roller brush holder. The end rollers can be close to the side wall of the template corner 61, facilitating the brushing of the template corner. As shown in Figure 9 , Figure 10 When brushing a groove template whose brushing width is only slightly larger than the width of the roller brush, it is not necessary to turn the roller brush, and both sides of the template can be brushed. As shown in Figure 11 .

[0034] Embodiment 2:
