DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] The present utility model provides as Figures 1-4A special-shaped hollow tube fixture shown in the figure includes a U-shaped clamping plate 1. Inside the U-shaped clamping plate 1, there is a bearing plate 2. At the top of the bearing plate 2, there are multiple fixing mandrels 3 for sleeving the special-shaped hollow tube 4. The fixing mandrel 3 includes a fixing rod 31. The bottom of the fixing rod 31 is fixed on the top surface of the bearing plate 2. A threaded hole 34 is opened inside the fixing rod 31. At the top of the fixing rod 31, multiple elastic flappers 32 are fixedly connected. The multiple elastic flappers 32 are arranged in a circular pattern. Inside the elastic flapper 32, there is a fastening screw 33. The nut of the fastening screw 33 is trapezoidal in shape, and the side of the nut is closely attached to the inner wall of the elastic flapper 32. The threaded part of the fastening screw 33 is threadedly connected to the threaded hole 34.
[0018] When the special-shaped hollow tube 4 is sleeved on the fixing mandrel 3, when the fastening screw 33 is rotated in the threaded hole 34 by a screwdriver, the fastening screw 33 moves downward. At this time, the head of the fastening screw 33 will squeeze the elastic flapper 32, causing the elastic flapper 32 to open outward, increasing the extrusion with the inner wall of the special-shaped hollow tube 4, and thus fixing the special-shaped hollow tube 4.
[0019] As Figure 1 shown in the figure, on the top surface of the U-shaped clamping plate 1, there is a pressing plate 5. On both sides of the pressing plate 5, multiple fixing holes 51 adapted to the top end of the special-shaped hollow tube 4 are opened.
[0020] Through the fixing holes 51, the top end of the special-shaped hollow tube 4 can be fixed, preventing the special-shaped hollow tube 4 from shaking when the fastening screw 33 is fixed by a screwdriver.
[0021] As Figure 2 shown in the figure, on one side of the bearing plate 2, there is a connecting plate 6 fixedly connected. A hole is opened in the middle of the connecting plate 6. On both sides of the connecting plate 6, there are bent plates 61 fixedly connected. The bent plates 61 are designed in a V shape.
[0022] Opening a hole in the middle of the connecting plate 6 facilitates the removal of the connecting plate 6 and the bearing plate 2 from the U-shaped clamping plate 1.
[0023] As Figure 3 shown in the figure, on the inner wall of the bottom of the U-shaped clamping plate 1, there are four limit blocks 7 for limiting the position of the bearing plate 2. The four limit blocks 7 are respectively arranged at the four corners of the inner wall of the bottom of the U-shaped clamping plate 1. Through the limit blocks 7, the bearing plate 2 and the connecting plate 6 can be fixed to prevent the bearing plate 2 from sliding in the U-shaped clamping plate 1.
[0024] As Figure 3 shown in the figure, the fixing hole 51 is designed in a conical shape. The fixing holes 51 on both sides of the pressing plate 5 are connected. Through the connection of the fixing holes 51, it is convenient for the screwdriver rod to pass through the fixing holes 51 to screw the fastening screw 33.
[0025] Working principle of the utility model: When in use, first put the special-shaped hollow tube 4 on the fixed mandrel 3, and then place the connecting plate 6 inside the U-shaped clamping plate 1. At this time, the bent plates 61 on both sides of the connecting plate 6 are elastically attached to the inner wall of the U-shaped clamping plate 1 to prevent the bearing plate 2 from shaking left and right in the U-shaped clamping plate 1. Subsequently, place the pressing plate 5 on the U-shaped clamping plate 1, so that a plurality of fixing holes 51 are stuck at the top of the corresponding special-shaped hollow tube 4, making the special-shaped hollow tube 4 tightly fixed to prevent it from shaking when fixed. Then, take out a screwdriver adapted to the fastening screw 33, pass through the fixing hole 51 to fix the fastening screw 33. After fixing, remove the pressing plate 5, then take out the bearing plate 2 from the U-shaped clamping plate 1, and then process the fixed special-shaped hollow tube 4.
[0026] Finally, it should be noted that the above are only the preferred embodiments of the utility model and are not used to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
