[0031] Reference Figure 1-6 A structure of an internal angle fastener for fixing a profile, comprising a handle 1, an inner cavity 2 is opened inside the handle 1, an adjusting bolt 3 is threadedly connected to the top of the inner cavity 2, an externally threaded sleeve 4 is fixedly connected to the bottom of the handle 1, an internally threaded sleeve 5 is threadedly connected to the surface of the externally threaded sleeve 4, a movable plate 6 is slidably connected to the inside of the inner cavity 2, an inner angle rod 8 is movably arranged inside the inner cavity 2, a limiting groove 10 is opened on the inner wall of the handle 1, a bottom plate 12 is fixedly connected to the outer wall of the inner angle rod 8, a baffle 14 is fixedly installed inside the handle 1, a top plate 15 is movably connected to the bottom of the inner cavity 2, one end of the top plate 15 is fixedly connected to one end of the inner angle rod 8, a fixing plate 18 is welded to the side wall of the handle 1, a notch 19 is opened on the side wall of the fixing plate 18, and a connecting rod 21 is rotatably connected to the inside of the notch 19.

[0032] Specifically, a snap-in groove 7 is provided on the surface of the movable plate 6, and the top end of the inner corner rod 8 is fixedly connected with a snap-in block 9 that matches the snap-in groove 7. Through the design of the snap-in groove 7 and the snap-in block 9, the inner corner rod 8 can be effectively fixed on the movable plate 6 to prevent it from loosening or falling off, while providing a reliable fixing force, ensuring the stability of the fastener, and increasing the applicability of the fastener.

[0033] Specifically, the side wall of the movable plate 6 is fixedly connected with a slider 11, and the slider 11 is slidably connected to the limit groove 10. This structure enables the inner corner fastener to have an adjustment function within a certain range. By sliding the slider 11, the position of the limit point can be changed to adapt to profiles of different sizes, thereby increasing the flexibility of the fastener. The number of sliders 11 and the limit grooves 10 are both two groups, and the sliders 11 and the limit grooves 10 are symmetrically distributed about the center of the movable plate 6. This structure can effectively balance the force lines of the fastener when it is subjected to force, and avoid deflection or instability caused by asymmetric force.

[0034] Specifically, one end of the base plate 12 is fixedly connected to the limit spring 13, and one end of the limit spring 13 is fixedly connected to one end of the baffle 14. This structure forms a fixed connection to ensure the stability of the internal structure. The base plate 12, the limit spring 13, the baffle 14 and the inner angle rod 8 form a telescopic structure. By turning the adjusting bolt 3, the adjusting bolt 3 is screwed forward into the middle cavity, the front end squeezes the inner angle rod 8, and the limit spring 13 is compressed and deformed, so that the front end of the inner angle rod 8 is exposed from the front end opening of the internal threaded sleeve 5, and the structure can be used as an inner angle wrench.

[0035] Specifically, one end of the top plate 15 is fixedly connected with a plurality of groups of corner columns 16, and the corner columns 16 are horizontally distributed along the axis of the top plate 15, so that the annular distribution of the corner columns 16 can provide multi-point support, so that the bearing capacity of the entire profile is evenly distributed, and the contact area and stability between the profile and the fastener are increased. The corner columns 16 are connected by compression springs 17 and are distributed in an annular shape. This structure can provide a certain elasticity to maintain the stability and tight connection of the corner columns 16.

[0036] Specifically, the side wall of the connecting rod 21 is sleeved with a handle 20 that is fixedly connected. By arranging the handle 20 on the connecting rod 21, the fasteners can be conveniently tightened or loosened. The outer wall of the handle 20 is slidably connected to the inner wall of the fixing plate 18. This structure enables the handle 20 to form a rotational connection with the fixing plate 18, which facilitates the retraction and extension of the handle 20. The side wall of the handle 20 is provided with anti-slip grooves. The side wall of the handle 20 is provided with anti-slip grooves, which can increase the friction between the hand and the handle 20, thereby reducing the possibility of the fasteners loosening or falling off due to hand sliding, which is particularly beneficial for occasions that require operation in a humid or greasy environment.

[0037] Specifically, the outer sleeve of the internal threaded sleeve 5 is fixedly connected with a rubber gasket 22. The rubber material has good wear resistance and corrosion resistance, so the rubber gasket 22 can maintain its performance in long-term use. It can effectively resist the erosion of water, chemicals and other external environmental factors, thereby ensuring the reliability and durability of the fastener.

[0038] Working principle: When using the device, the multiple corner columns 16 are kept in a circular distribution shape by compressing the spring 17. The number of corner columns 16 matches the head shape of the internal angle bolt. By manually twisting the handle 1, the bottom of the internal threaded sleeve 5 of the handle 1 is rotated and screwed in. The top of the handle 1 squeezes the corner column 16, so that the corner column 16 moves forward toward the opening of the internal threaded sleeve 5, so that the internal threaded sleeve 5 is gradually exposed. In the process of the handle 1 squeezing the corner column 16 forward, the front end of the corner column 16 is in close contact with the inner wall of the conical head of the internal threaded sleeve 5. The conical head has a guiding function, and the front ends of all the corner columns 16 gradually narrow and close toward the center, and the rear ends gradually expand toward the outside of the center. When in use, the maintenance personnel place the corner column 16 on the internal angle bolt to be installed or removed, and then adjust the opening and closing degree of the front end of the corner column 16 by turning the handle 1 until it is tightly sleeved on the head of the bolt. Since the front end of the corner column 16 is embedded in the bolt head, the outer side of the corner column 16 is supported by the opening edge of the internal threaded sleeve 5, and the rear end is supported by the top of the handle 1, so it can remain embedded when the bolt is turned.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
