[0001] The present application relates to the technical field of garden maintenance, and in particular to a plastic tool brush for whitewashing tree trunks. Background Art

[0002] In the maintenance of gardening and greening, tree pest control is an important part, and the protection of the main trunk is its main part. Whitewashing the trunk is an effective means to protect the main trunk. By mixing quicklime, water and other substances and brushing them 1 to 1.5 meters above the ground, the purpose of killing insects, preventing insects, killing bacteria and healing wounds can be achieved to a large extent.

[0003] In the current tree trunk whitewashing process, a liquid bucket is usually used as a container, and 1 to 3 people operate a wooden brush or roller to work around the tree trunk according to the size of the tree diameter. However, there are the following problems when operating a wooden brush: 1. The existing tool has a small coverage area, resulting in low brushing efficiency and high labor costs; 2. The existing tool handle is short and the height is variable during operation, which is not conducive to long-term operation; 3. The bristles of the wooden brush are rough and easy to fall off, which is easy to scratch the soft bark during operation. The roller cannot penetrate into the gaps of some tree trunks due to its smooth brushing surface.

[0004] In this regard, although the patent application number CN113289790A discloses a new type of handheld annular tree trunk whitening mechanism, including a fixed end, an extension mechanism and a retracting mechanism, the user can adjust the retracting mechanism and the extension mechanism to adapt the entire device to the size of the tree trunk, so as to achieve 360° surrounding spraying of the tree trunk with high spraying efficiency. However, the device has a complex structure, resulting in high cost and is difficult to promote and use. Utility Model Content

[0026] The following further details the present application through specific embodiments in conjunction with the accompanying drawings.

[0027] In the description of the present application: Unless otherwise specified, the meaning of "a plurality" is two or more. Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0028] Terms such as "upper", "lower", "left", "right", "middle", etc. cited in the present application are generally indications of the general relative position relationship for the convenience of intuitively understanding with reference to the accompanying drawings, and are not absolute limitations on the position relationship in the actual product.

[0029] A plastic deformable tool brush for whitening tree trunks, referring to Figures 1 - 3 , includes a grip rod 1, a brush head 2 and bristles 3. Among them, in order to facilitate bending and shaping of the brush head 2, a plurality of iron wires 4 are arranged inside the brush head 2. The iron wires 4 can be bent and shaped, and can be adaptively adjusted according to the shape of the tree trunk. The outside of the brush head 2 is wrapped with a stainless steel iron sheet material, and the iron sheet is a deformable material and can be bent and shaped under the action of an external force. Therefore, before brushing the tree trunk, the shape of the brush head 2 can be manually bent and adjusted to match the vertical rod according to the tree diameter of the tree trunk, so that the brushing operation can be carried out more efficiently.

[0030] In this embodiment, a linear iron wire 4 with a length of 30 cm - 40 cm and a diameter of 1 mm is used. The number of iron wires 4 inside the brush head 2 is 20 - 40, and the mass range is 0.14 kg - 0.4 kg. In other embodiments, the length and number of the iron wires 4 can be adaptively adjusted according to the size of the brush head 2.

[0031] Specifically, the external shape of the brush head 2 is a semi-cylindrical structure, and bristles 3 with a length of 4 cm - 6 cm are installed at the plane position. The bristles 3 are made of a material with a moderate texture. While ensuring that the bristles 3 can normally brush the tree trunk to avoid gaps, it will not scratch the surface of the tree bark. In this embodiment, the length of the bristles 3 is 5 cm.

[0032] The cylindrical surface of the brush head 2 is connected to the grip rod 1, and the connection point is at the central position in the length direction of the brush head 2.

[0033] Among them, the brush head 2 and the handle rod 1 are rotationally connected. Specifically, one end of the handle rod 1 is rotationally connected, and the axis of a rotating shaft is perpendicular to the handle rod 1. Correspondingly, mounting ears matching the rotating shaft are installed on the cylindrical surface of the brush head 2 to provide a mounting position for the rotating shaft. After installation, the axis of the rotating shaft should be parallel to the length direction of the brush head 2, so that the brush head 2 can swing up and down. When painting different heights of the tree trunk, the worker stands still at one position and drives the brush head 2 to paint from top to bottom or from bottom to top. During the painting process, the brush head 2 will swing naturally, so that the bristles 3 can always face the surface of the tree trunk. The worker does not need to move the position, greatly reducing the labor intensity.

[0034] Among them, the handle rod 1 is a telescopic structure. The handle rod 1 includes a fixed part 11 and a telescopic part 12. Both the fixed part 11 and the telescopic part 12 are cylindrical structures. A sliding groove for the telescopic part 12 to insert is opened inside the fixed part 11. A part of the telescopic part 12 is inserted into the sliding groove and can slide back and forth axially in the sliding groove. Among them, one end of the fixed part 11 away from the telescopic part 12 is connected to the brush head 2.

[0035] A limit screw 13 for restricting the sliding of the telescopic part 12 is also penetrated on the fixed part 11. In one embodiment, a plurality of through holes can be axially opened on the telescopic part 12. Slide the telescopic part 12 to adjust the through hole corresponding to the limit screw 13. After the telescopic part 12 is adjusted to a suitable position, the limit screw 13 is inserted into the through hole to fix the telescopic part 12. This fixing method is more stable and reliable after fixing. In another embodiment, no through holes are opened on the telescopic part 12. Rotate the limit screw 13, and the limit screw 13 can move away from or close to the telescopic part 12. When the telescopic part 12 needs to be fixed, rotate to drive the limit screw 13 to press against the telescopic part 12, and use the friction between the two to fix the telescopic part 12. This fixing method is more convenient and can fix the telescopic part 12 at any position in its movement path. If the second fixing method is adopted, an anti-slip pad can be provided at the end of the limit screw 13 to increase the friction between the limit screw 13 and the telescopic part 12 and improve the stability of the handle rod 1.

[0036] The implementation principle of the embodiment of the present application is: when painting the tree trunk white, adjust the length of the handle rod 1, and bend and shape the brush head 2 to conform to the size of the tree diameter. At this time, the operator dips the whitewashing liquid from the whitewashing liquid bucket and paints the surface of the tree trunk from top to bottom or from bottom to top. Driven by the rotating shaft, the operator can complete the painting operation in the same posture.

[0037] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written out should also be considered to be within the scope described in this specification.
