[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example: See Figures 1 to 4 According to an embodiment of the utility model, a technical solution is provided: an adjustable building formwork fastening device, comprising a building formwork body 1 and a base plate 2 suitable for bearing the building formwork, and also comprising a fastening mechanism, the fastening mechanism comprising a fastening seat 3, which is fixed to the top of the base plate 2, and a fastening groove 4 is provided in the fastening seat 3 along its width direction; a clamping column 5, which is movably arranged in the fastening groove 4, and a threaded guide groove 6 is provided on the clamping column 5, a limiting column 7 is provided on the fastening seat 3, and the limiting column 7 is provided in the guide groove 6; a fastening part 8, which is movably arranged in the fastening groove 4, and a spring 9 is provided between the fastening part 8 and the clamping column 5, and the two ends of the spring 9 elastically abut the fastening part 8 and the clamping column 5 respectively.

[0025] With the adjustable building formwork fastening device of the above structure, when the user needs to adjust the fastening force on the building formwork body 1, first, the pressing column 5 is rotated forward or reversed. Since the limiting column 17 is fixed to the fastening seat 3 and embedded in the threaded guide groove 16 of the pressing column 5, the rotation of the pressing column 5 is converted into movement in the length direction of the fastening groove 4. During this process, if the pressing column 5 moves toward the fastening portion 8, the spring 9 will be compressed, thereby increasing its thrust on the fastening portion 8. This thrust is transmitted to the building formwork body 1 through the pressing column 5, achieving a tighter fixation of the building formwork body 1. On the contrary, if the pressing column 5 moves in a direction away from the fastening portion 8, the spring 9 will gradually relax, reducing the fastening force on the building formwork body 1, making it easier for the user to adjust the fastening force on the building formwork body 1.

[0026] In this embodiment, a guide groove 2 10 is provided at the top of the fastening portion 8 along its length direction, and a limiting column 2 11 is provided on the fastening column, and the limiting column 2 11 is arranged in the guide groove 2 10; the guide groove 2 10 limits the moving direction of the fastening portion 8, ensuring that the fastening portion 8 can only move in a straight line along the length direction of the guide groove 2 10, avoiding unnecessary rotation or deviation, and increasing the stability of the fastening portion 8 during movement.

[0027] In this embodiment, the compression column 5 defines a compression chamber 12, in which a piston 13 is movably disposed. A guide column 14 is fixed to one side of the piston 13. The guide column 14 movably extends through the first end of the compression column 5. The fastening portion 8 is provided with a notch 15, in which the free end of the guide column 14 is movably disposed. When the user rotates the compression column 5 forward, the compression column 5 moves toward the fastening groove 4, thereby driving the guide column 14 to insert into the notch 15. When the bottom of the guide column 14 contacts the bottom of the notch 15, if the user continues to rotate the compression column 5, the guide column 14 presses against the piston 13. The movement of the piston 13 changes the volume of the compression chamber 12, which in turn may cause a change in the pressure within the compression chamber 12, thereby increasing the pressure exerted by the free end of the guide column 14 on the fastening portion 8. In other words, as the compression column 5 continues to rotate and the piston 13 moves, the fastening force applied to the building formwork body 1 also increases accordingly, further raising the upper limit of the fastening force.

[0028] In this embodiment, a screw disk 16 is fixed to the second end of the compression column 5 ; when the user needs to rotate the compression column 5 , the screw disk 16 provides the user with a fulcrum for rotating the screw disk 16 , so that the user can rotate the screw disk 16 easily.

[0029] In this embodiment, a plurality of friction-increasing protrusions 17 are provided on the dial 16 at intervals along its circumference; when the user rotates the dial 16 , the friction-increasing protrusions 17 increase the friction between the user's fingers and the dial 16 , making it easier for the user to rotate the dial 16 .

[0030] In this embodiment, the fastening base 3 and the base plate 2 are detachably connected; when the user needs to replace or maintain the fastening base 3, the fastening base 3 can be disassembled from the base plate 2 in a detachable manner, thereby facilitating the user to replace or maintain the fastening base 3.

[0031] Working principle: When the user needs to adjust the fastening force of the building formwork body 1, first, rotate the clamping column 5 forward or reverse. Since the limiting column 7 is fixed on the fastening seat 3 and embedded in the threaded guide groove 6 of the clamping column 5, the rotation of the clamping column 5 is converted into movement in the length direction of the fastening groove 4. During this process, if the clamping column 5 moves toward the fastening part 8, the spring 9 will be compressed, thereby increasing its thrust on the fastening part 8. This thrust is transmitted to the building formwork body 1 through the clamping column 5, thereby achieving a tighter fixation of the building formwork body 1. On the contrary, if the clamping column 5 moves in the direction away from the fastening part 8, the spring 9 will gradually relax, reducing the fastening force on the building template body 1, making it easier for the user to adjust the fastening force on the building template body 1; the guide groove 2 10 will limit the moving direction of the fastening part 8, ensuring that the fastening part 8 can only move linearly along the length direction of the guide groove 2 10, avoiding unnecessary rotation or deviation, and increasing the stability of the fastening part 8 during movement; when the user rotates the clamping column 5 forward, the clamping column 5 will move toward the fastening groove 4, thereby driving the guide column 14 to insert into the notch 15. When the bottom of the guide column 14 contacts the bottom of the notch 15, if the user continues to rotate the clamping column 5, the guide column 14 will press against the piston 13, and the movement of the piston 13 will change the volume in the clamping chamber 12, which may cause a change in the pressure in the clamping chamber 12, so that the pressure of the free end of the guide column 14 on the fastening part 8 increases. In other words, as the compression column 5 continues to rotate and the piston 13 moves, the tightening force exerted on the building formwork body 1 will also increase accordingly, further increasing the upper limit of the tightening force; when the user needs to rotate the compression column 5, the dial 16 will provide the user with a fulcrum for rotating the dial 16, so that the user can rotate the dial 16; when the user rotates the dial 16, the friction-increasing protrusion 17 will increase the friction between the user's finger and the dial 16, so that the user can rotate the dial 16; when the user needs to replace or maintain the fastening base 3, the fastening base 3 can be disassembled and assembled from the base plate 2 in a detachable manner, thereby facilitating the user to replace or maintain the fastening base 3.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
