[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Referring to Figures 1-4 , the formwork removal tool in a narrow groove includes a first insertion block 1 and a second insertion block 2. The first insertion block 1 and the second insertion block 2 are symmetrically arranged with respect to each other, and the ends away from each other are both inclined surfaces. Two first connecting rods 3 are connected to one end of the first insertion block 1. The two first connecting rods 3 are parallel and symmetric to each other. A second connecting rod 4 is connected to the same end of the second insertion block 2. The second connecting rod 4 is cross-rotatably connected between the two first connecting rods 3. A nut 5 is rotatably connected between the ends of the two first connecting rods 3 away from the first insertion block 1. A long screw rod 6 is threadedly connected in the nut 5. A notch 7 is provided at the end of the second connecting rod 4 away from the second insertion block 2. The long screw rod 6 can be located in the notch 7. A first handle 8 is rotatably connected to one end of the long screw rod 6. A second handle 9 is rotatably connected in the first handle 8.

[0022] Through the inclined surface design of the first insertion block 1 and the second insertion block 2, the first insertion block 1 and the second insertion block 2 can be inserted between the formwork and the concrete in the combined state. The cross-rotatable connection between the first connecting rod 3 and the second connecting rod 4 enables the separation and combination between the first insertion block 1 and the second insertion block 2 when an external force acts on the first connecting rod 3 and the second connecting rod 4, thereby realizing the separation between the formwork and the concrete, and the purpose of clamping and removing the formwork from the groove after separation. The operation is relatively convenient. Through the cooperation between the nut 5, the long screw rod 6, the first handle 8 and the second handle 9, the second handle 9 drives the first handle 8 to make the long screw rod 6 screw into the nut 5, so that the first handle 8 generates a pressure on the second connecting rod 4, and further makes the first insertion block 1 and the second insertion block 2 produce a separation effect, making the separation between the formwork and the concrete more labor-saving and convenient, effectively saving manpower.

[0023] Specifically, in this embodiment, tooth grooves 10 are provided on the surfaces of the first insertion block 1 and the second insertion block 2 that are in contact with each other to prevent the problem of slipping when clamping and taking out the formwork from the groove.

[0024] Specifically, in this embodiment, a first fixed shaft 11 is connected between two first link rods 3. The first fixed shaft 11 is arranged at the intersection of the first link rod 3 and the second link rod 4. The second link rod 4 is rotatably connected to the first fixed shaft 11, connecting the first link rod 3 and the second link rod 4 into a whole, and providing a unified fulcrum for the rotation between the first link rod 3 and the second link rod 4.

[0025] Specifically, in this embodiment, support shafts 12 are connected to both ends of the nut 5. The two support shafts 12 are respectively rotatably connected inside the first link rods 3 at corresponding positions, providing a fulcrum for the angular rotation of the nut 5 between the two first link rods 3, while improving the connection effect between the nut 5 and the first link rods 3 to prevent separation, thereby achieving the effect that the long screw 6 is screwed into the nut 5 and remains stationary.

[0026] Specifically, in this embodiment, the first handle 8 is composed of two clamping plates 13, a second fixed shaft 14, and a third fixed shaft 15. The second fixed shaft 14 and the third fixed shaft 15 are respectively connected between the two ends of the two clamping plates 13. The second fixed shaft 14 is rotatably connected inside the long screw 6, and the second handle 9 is rotatably connected to the third fixed shaft 15, realizing the connection between the long screw 6, the first handle 8, and the second handle 9, and enabling the first handle 8 to freely adjust its angle on the long screw 6, ensuring the stable effect when generating pressure on the second link rod 4, and realizing the rotational folding of the second handle 9 inside the first handle 8.

[0027] Specifically, in this embodiment, the width between the outer walls of the two clamping plates 13 is greater than the width of the notch 7 and less than the distance between the two first link rods 3. Rubber pads can be added to the outer walls of the two clamping plates 13 to facilitate the first handle 8 to generate pressure on the second link rod 4, and when the nut 5, the long screw 6, and the first handle 8 rotate to the two first link rods 3, they can be received inside the two first link rods 3. Adding rubber pads can improve the stability of the first handle 8 when received between the two first link rods 3.

[0028] Specifically, in this embodiment, the width of the second handle 9 is less than the distance between the two clamping plates 13. Rubber sleeves can be added to the outer wall of the second handle 9 to realize the reception of the second handle 9 inside the first handle 8. Adding rubber sleeves can improve the stability of the reception of the second handle 9 and the comfort of manually holding the second handle 9.

[0029] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
