[0037] A self-adjusting component 7 is mounted on the inner side of the middle of the transition cover 2. The self-adjusting component 7 includes a composite conduit 71, a movable stopper 72 and a reset component 73. The composite conduit 71 is clamped on the inner side of the opening structure at the top of the raw material soft bottle 1. The movable stopper 72 is clamped on the inner side of the middle of the composite conduit 71 and separates the top space and the bottom space of the composite conduit 71. The inner side of the top of the composite conduit 71 is an inverted conical tubular structure. The self-adjusting component 7 is used as a transition conveying structure. During the use of the raw material soft bottle 1, it will open its own conveying channel only after being subjected to a certain pressure, thereby ensuring the stability and reliability of the raw material soft bottle 1 when it is not necessary to discharge the material.

[0038] A platform structure is provided on the inner side of the middle part of the composite conduit 71, and a step hole is opened in the platform structure.

[0039] Working principle: When in use, squeeze the raw material soft bottle 1, so that the repair material inside the raw material soft bottle 1 enters the material delivery channel inside the material guide brush head 3 through the clearance hole in the transition cover 2, and then flows out of the material guide brush head 3 and fully contacts with multiple groups of brush strip components 4. Then, hold the raw material soft bottle 1 to make the brush strip components 4 reciprocate and brush at the position to be repaired on the wall, so as to achieve a targeted and flexible repair effect;

[0040] During the discharge of the raw material soft bottle 1, the movable stopper 72 inside the self-adjusting component 7 will move after being pressed by the raw material, and then make way for the internal space of the composite conduit 71, and then the raw material will enter the transition cover 2 through the composite conduit 71. In addition, when the raw material soft bottle 1 is held and used without feeding, the movable stopper 72 will stably block the middle part of the composite conduit 71 under the stretching limit of the T-bar 731 and the spring 732 inside the reset component 73, so as to avoid the self-flow of raw materials when they are not used.

[0041] During the reciprocating use of the entire device, the buffer rod 8 damps and buffers the vibration suffered by the connection between the raw material soft bottle 1 and the transition cover 2, thereby reducing the probability of the raw material soft bottle 1 and the transition cover 2 being separated during use. For the unused repair material inside the raw material soft bottle 1, the transition cover 2 can be removed by twisting and then separated from the top of the raw material soft bottle 1. Then, the sealing cover 5 is threadedly connected to the opening structure at the top of the raw material soft bottle 1 for sealing protection.
