[0005] Preferably, the push block is fixedly installed with the blade, and the push block drives the blade to slide and connect inside the handle. Here, it is convenient for people to use the telescopic knife, and under the action of the handle, people can be prevented from being accidentally injured by the blade.

[0006] Preferably, the bamboo knife is located on the bottom surface of the telescopic knife, the bamboo stick is located on the bottom surface of the bamboo knife, the brush is located on the bottom surface of the bamboo stick, and the telescopic knife, the bamboo stick, the bamboo knife and the brush are parallel to each other. Here, the smoothness of the tool brush during use can be improved to avoid jamming during rotation.

[0007] Preferably, a cross hole is provided on the end surface of the rotating shaft. Here, the cross hole can be used to facilitate personnel to disassemble and assemble the threaded joint and the rotating shaft, so that personnel can maintain and replace various tools on the tool brush.

[0008] Preferably, the elastic block is between the handle and the surface of the bamboo knife, and the elastic force of the elastic block presses the telescopic knife, bamboo knife, bamboo stick and brush against the surface of the rotating shaft. Here, when the tool brush is not in use, the various tools in the tool brush can be stored to avoid being loose and affecting carrying.

[0009] Compared with the prior art, the advantages and positive effects of the utility model are:

[0010] In the utility model, the tool brush consists of a bamboo stick, a telescopic knife, a brush and a bamboo knife. One ends of the four tools are fixed on a rotating shaft. When in use, according to the excavation needs of cultural relics, the elastic block is pressed to elastically deform the elastic block, thereby causing the telescopic knife, the bamboo knife, the bamboo stick and the brush to loosen. The bamboo stick, the telescopic knife, the brush and the bamboo knife are rotated 180 degrees, and the elastic block is reset to squeeze and fix the telescopic knife, the bamboo knife, the bamboo stick and the brush again, so that it is convenient for personnel to use the tool brush to excavate and clean the cultural relics, avoid the inconvenience of taking too many tools during the excavation process, and improve the convenience of use for personnel.

[0015] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

[0017] See also Figure 1-2The utility model provides a technical solution: an adjustable tool brush, including a brush 1, a bamboo stick 2, a bamboo knife 3 and a telescopic knife 4, the brush 1 includes a brush handle 11 and a brush head 12, the telescopic knife 4 includes a knife handle 41, a push block 42 and a blade 43, the push block 42 and the blade 43 are fixedly installed, and the push block 42 drives the blade 43 to slide and connect inside the knife handle 41, which can facilitate personnel to use the telescopic knife 4. Under the action of the knife handle 41, personnel can be prevented from being accidentally injured by the blade 43. A rotating shaft 5 is inserted into the brush 1, the bamboo stick 2, the bamboo knife 3 and the telescopic knife 4, a screw hole 52 is opened inside the rotating shaft 5, and a threaded joint 53 is connected to the internal thread of the screw hole 52, the bamboo knife 3 is located on the bottom surface of the telescopic knife 4, the bamboo stick 2 is located on the bottom surface of the bamboo knife 3, the brush 1 is located on the bottom surface of the bamboo stick 2, and the telescopic knife 4, bamboo stick 2, bamboo knife 3 and brush 1 are parallel to each other, which can improve the smoothness of the tool brush during use and avoid jamming during rotation. A cross hole 51 is provided on the end surface of the rotating shaft 5, and the cross hole 51 can be used to facilitate personnel to disassemble and assemble the threaded joint 53 and the rotating shaft 5, so that personnel can maintain and replace various tools on the tool brush. An elastic block 44 is fixedly installed on the surface of the knife handle 41, and the elastic block 44 is between the knife handle 41 and the surface of the bamboo knife 3. The elastic force of the elastic block 44 presses the telescopic knife 4, bamboo knife 3, bamboo stick 2 and brush 1 on the surface of the rotating shaft 5. When the tool brush is not in use, the various tools in the tool brush can be stored to avoid loosening and affecting carrying.

[0018] Working principle: When using a tool brush to clean cultural relics, different tools on the tool brush are used according to different cultural relics. When it is necessary to cut debris around the cultural relics during the cleaning process, the blade 43 is pushed out of the handle 41 by pushing the push block 42, so that the personnel can use the blade 43 to cut the debris around the cultural relics into small pieces for removal. When it is necessary to excavate the cultural relics, the elastic block 44 is pressed to elastically deform the elastic block 44, so that the telescopic knife 4, the bamboo knife 3, the bamboo stick 2 and the brush 1 are loosened. According to the excavation requirements of the cultural relics, the bamboo knife 3, the bamboo stick 2 or the brush 1 is moved on the rotating shaft 5. The tool 4 is rotated 180°, and then the elastic block 44 is reset, so that the elastic block 44 squeezes and fixes the telescopic knife 4, bamboo knife 3, bamboo stick 2 and brush 1 again, so as to facilitate personnel to use the tool brush to excavate and clean the cultural relics, avoid the inconvenience of taking too many tools during the excavation process, and improve the convenience of use for personnel. If the tool brush needs to be maintained or replaced, the personnel can remove the threaded joint 53 from the rotating shaft 5 through the cross hole 51, thereby removing the telescopic knife 4, bamboo knife 3, bamboo stick 2 and brush 1 from the rotating shaft 5, and maintain and replace the corresponding tools according to the use of the tools.
