DETAILED DESCRIPTION

[0019] 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 and not 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 scope of the utility model.

[0020] Embodiment one

[0021] Please refer to Figures 1-4 The utility model provides the following technical scheme: a multifunctional polishing tool of adjustable angle, including first mounting rod 1, second mounting rod 2, pivot 3, polishing plate 4 and spring 5, the inner side wall of polishing plate 4 is installed with rotating block 10, and the inner side wall of first mounting rod 1 and second mounting rod 2 is seted with rotating groove 11 and moving groove 12, and the surface of first mounting rod 1 and second mounting rod 2 is seted with threaded groove 13, and the inside of threaded groove 13 is connected with threaded rod 14, and the end of threaded rod 14 is installed with fixed block 15, and the end of fixed block 15 is connected with concave block 16, and the surface of concave block 16 is connected with pin shaft 17.

[0022] In the preferred embodiment, the rotating block 10 is adapted to the size of the rotating groove 11, and the size of the rotating groove 11 is greater than the size of the moving groove 12.

[0023] In the preferred embodiment, the polishing plate 4 is swingably connected between the first mounting rod 1 and the second mounting rod 2 through the rotating block 10, the rotating groove 11 and the moving groove 12.

[0024] In the preferred embodiment, the concave block 16 is connected to the back end of the polishing plate 4, and the polishing plate 4 is threadedly connected between the first mounting rod 1 and the second mounting rod 2 through the threaded rod 14 and the concave block 16.

[0025] In the embodiment, during the assembly of the glass curtain wall, the sub-frame needs to be polished to ensure the smoothness of the connection. First, the operator holds the end of the first mounting rod 1 and the second mounting rod 2 and applies appropriate extrusion force. This action immediately causes the spring 5 to shrink and deform, thereby starting to adjust the included angle position between the first mounting rod 1 and the second mounting rod 2.

[0026] At the same time, the operator rotates the threaded rod 14 to move it outward. During the rotation of the threaded rod 14 inside the fixed block 15, the angle of the polishing plate 4 changes accordingly. This change is achieved by the rotation of the rotating block 10 connected to the polishing plate 4 inside the rotating groove 11, and the rotating block 10 moves along the moving groove 12 to ensure the stability of the angle adjustment. At the same time, the fixed block 15 rotates along the top end of the recess 16 through the pin shaft 17, which ensures the stability of the rotation of the threaded rod 14 and prevents the threaded rod 14 from adjusting with the angle change of the polishing plate 4.

[0027] Through the above process, the angle position of the polishing plate 4 is adjusted to perfectly adapt to the change of the included angle between the first mounting rod 1 and the second mounting rod 2. In this way, the polishing plate 4 can stably adhere to the external corner position of the sub-frame and maintain continuous and uniform polishing of the external corner of the sub-frame when moving up and down.

[0028] Furthermore, the operator does not need to frequently adjust the polishing position, which effectively avoids uneven and uneven polishing problems, thereby greatly improving the polishing efficiency and polishing quality.

[0029] Embodiment two

[0030] Please refer to Figures 1-4 , the top end of the first mounting rod 1 is connected with the first half ring column 6, and the top end of the first half ring column 6 is threadedly connected with the bolt 9.

[0031] In the preferred embodiment, the top end of the second mounting rod 2 is connected with the second half ring column 7, and a group of positioning grooves 8 are evenly arranged at the top end of the second half ring column 7.

[0032] In the preferred embodiment, the second half ring column 7 is sleeved inside the first half ring column 6, and the second half ring column 7 and the first half ring column 6 are detachably fixedly connected through the bolt 9 and the positioning groove 8.

[0033] In the embodiment, according to the description in embodiment one, when adjusting the included angle between the first mounting rod 1 and the second mounting rod 2, first, the operator needs to remove the bolt 9 from the connection between the first half ring column 6 and the second half ring column 7 to allow the included angle to change. With the adjustment of the included angle, the second half ring column 7 smoothly extends into the inside of the first half ring column 6 to realize the relative movement between the two.

[0034] When the included angle of the first mounting rod 1 and the second mounting rod 2 is adjusted to the desired position, the operator takes out the bolt 9 again and re-threads it to firmly fix the second half ring column 7 inside the first half ring column 6. This step ensures that the included angle between the first mounting rod 1 and the second mounting rod 2 remains stable, and also ensures that the polishing plate 4 can closely fit the profile of the external corner of the secondary frame for polishing.

[0035] Thus, the flatness and uniformity of polishing are further improved, and the labor required for the operator to continuously maintain the stability of the included angle between the first mounting rod 1 and the second mounting rod 2 is effectively reduced. This improvement makes the entire polishing process more efficient and convenient.

[0036] It is worth noting that: the polishing tool not only can clamp the external corner of the secondary frame, but also can clamp the side wall of the secondary frame, and then the polishing plate 4 on the first mounting rod 1 and the second mounting rod 2 is distributed in an up-down manner, which can polish one side wall of the secondary frame. Thus, the multifunctional of the polishing tool is realized.

[0037] Finally, it should be noted that: the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
