DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] Embodiment 1: please refer to Figures 1-4 A multi-roller paint brush, comprising a mounting rack 4, a rotating shaft 51 is rotatably connected to the mounting rack 4, the bottom of the rotating shaft 51 is fixedly connected with a roller rack 5, limit hole one 52 and limit hole two 53 are respectively formed in the roller rack 5, a limit assembly 6 is arranged on the mounting rack 4, the limit assembly 6 comprises a limit rod 63, the limit rod 63 penetrates and is slidably installed on the mounting rack 4, the limit rod 63 is matched with the two limit holes, the top of the limit rod 63 is fixedly connected with a handle 61, the handle 61 is arranged above the mounting rack 4, and the handle 61 is connected with the mounting rack 4 through a spring 62.

[0022] Specifically, in the initial state, the limit rod 63 is inserted into the limit hole one 52 or the limit hole two 53 on the roller rack 5 under the action of the spring 62, so that the roller rack 5 is fixed on the mounting rack 4, at this time, the roller rack 5 is in a stable working position, and the roller can roll in the corresponding direction to perform paint construction, when it is necessary to change the state of the roller rack 5, an operator holds the handle 61 and pulls it upwards, the handle 61 drives the limit rod 63 to slide upwards along the mounting rack 4, the spring 62 is stretched, the limit rod 63 gradually separates from the currently inserted limit hole, the handle 61 is continuously pulled until the limit rod 63 completely separates from the limit hole, then the roller rack 5 is rotated around the rotating shaft 51, so that the positions of the limit hole one 52 and the limit hole two 53 are exchanged. Then the handle 61 is released, the spring 62 restores the deformation, the handle 61 and the limit rod 63 are pushed downwards, the limit rod 63 is inserted into the other limit hole, so that the roller rack 5 is fixed in the new position, and the state change of the roller rack 5 is realized.

[0023] By changing the state of the roller frame 5, the roller can be used for paint application in different rolling directions, so as to better adapt to the surface of objects of various shapes. When the limiting rod 63 is inserted into the limiting hole two 53, the rolling direction of the roller is suitable for large-area brushing of planar objects; when the limiting rod 63 is inserted into the limiting hole one 52, the rolling direction of the roller can be adjusted to be more suitable for brushing curved surface objects such as cylinders and arcs, so as to ensure that the paint can uniformly cover the surfaces of different shapes and improve the quality and effect of paint application.

[0024] In order to adapt to different working environments, please refer to Figures 1-4 On the basis of embodiment 1, the top of the mounting frame 4 is fixedly installed with a rotating frame 41, the rotating frame 41 is rotationally connected with the connecting head 3, one end of the connecting head 3 is fixedly connected with the extension rod 2, and the extension rod 2 is sleeved in the inside of the holding rod 1;

[0025] The inner wall of the holding rod 1 is provided with a sliding groove 14 on both sides, and the extension rod 2 is fixedly installed with a limiting block 21 on both sides away from the connecting head 3, the limiting block 21 is matched with the sliding groove 14, and the extension rod 2 is a hollow pipe;

[0026] One end of the holding rod 1 is rotationally connected with a handle 12, the handle 12 is fixedly connected with a screw rod 13, the screw rod 13 is arranged in the inside of the holding rod 1, and the screw rod 13 is screwedly connected with the extension rod 2;

[0027] The outer sides of both ends of the holding rod 1 are circumferentially provided with anti-skid pads 11.

[0028] Specifically, when it is necessary to lengthen the tool, the operator rotates the handle 12 clockwise, and the handle 12 drives the screw rod 13 to synchronously rotate clockwise in the holding rod 1. Since the screw rod 13 is screwedly connected with the extension rod 2, the rotation of the screw rod 13 will make the extension rod 2 slide linearly along the inner wall of the holding rod 1 in a direction away from the handle 12 under the limiting and guiding actions of the limiting block 21 and the sliding groove 14, so as to make the extension rod 2 extend out of the holding rod 1, and the length of the tool is increased. When it is necessary to shorten the tool, the operator rotates the handle 12 counterclockwise, the screw rod 13 rotates counterclockwise, and the extension rod 2 slides towards the handle 12, so as to make the extension rod 2 retract into the holding rod 1, and the length of the tool is shortened;

[0029] By extending the telescopic rod 2 in the holding rod 1, the overall length of the tool can be flexibly adjusted according to the actual operation requirements. When the surface of an object at a long distance or a high position is painted, the telescopic rod 2 can be extended to a long length to expand the operation range, so that the difficult-to-reach area can be easily reached without the help of climbing equipment or excessive stretching of the body. When painting in a small space or a detailed part, the length needs to be adjusted to a shorter length to ensure the accuracy of the operation. The telescopic length can be easily adjusted to adapt to various scenes, enhance the versatility and practicality of the tool, and improve the work efficiency and convenience.

[0030] Working principle: initially, the limiting rod 63 is inserted into the limiting hole one 52 or the limiting hole two 53 under the action of the spring 62, and the roller connected with the roller frame 5 is used for normal rolling construction. If the state of the roller frame 5 needs to be changed, the operator holds the handle 61 and pulls it upwards, drives the limiting rod 63 to slide upwards, stretches the spring 62, and makes the limiting rod 63 completely separate from the current limiting hole. Then, the roller frame 5 is rotated around the rotating shaft 51, and the positions of the limiting hole one 52 and the limiting hole two 53 are interchanged. Then, the handle 61 is released, the spring 62 pushes the handle 61 and the limiting rod 63, the limiting rod 63 is inserted into the other limiting hole, the roller frame 5 is fixed at the new position, and the rolling direction of the roller is changed to adapt to the surface of an object of different shapes.

[0031] When the length of the tool needs to be extended, the operator rotates the handle 12 clockwise, drives the screw rod 13 to rotate clockwise, and under the action of the limiting block 21 and the sliding groove 14, the extension rod 2 slides linearly along the inner wall of the holding rod 1 to the direction away from the handle 12 to extend the length of the tool. To shorten the length of the tool, the operator rotates the handle 12 counterclockwise, the screw rod 13 rotates counterclockwise, and the extension rod 2 slides to the direction of the handle 12 to retract.

[0032] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above-mentioned exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model.
