[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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.

[0023] Refer to Figures 1-5 , a formwork fixing fixture, including a connecting member 1 and a clamping member 2. The side of the connecting member 1 has an opening. An upper clamping plate 11 and a connecting part 12 are respectively arranged on both sides of the opening. The clamping member 2 is arranged in the connecting part 12 and has a lower clamping plate 21 at its top;

[0024] Among them, a tripping component 3 is arranged in the connecting part 12, and the tripping component 3 is used to lock and unlock the clamping member 2.

[0025] It is worth mentioning that the connecting member 1 is the main body of the fixture. The main body of the fixture has a U-shaped structure. The clamping member 2 is an auxiliary clamping body, which is used to cooperate with the main body of the fixture to clamp and fix the formwork and the steel reinforcement cage.

[0026] Furthermore, the tripping component 3 includes a tooth groove 31. The clamping member 2 has a rod-shaped structure and is slidably connected to the connecting part 12. A plurality of the tooth grooves 31 are equidistantly arranged along the axis on the periphery of the bottom of the clamping member 2, and a pushing and pulling part 22 is also fixed at the bottom of the clamping member 2.

[0027] Specifically, the pushing and pulling part 22 is threadedly connected to the bottom of the clamping member 2, which is convenient for disassembly and replacement. Concave grooves are arranged at both ends of the pushing and pulling part 22, which is convenient for the staff to pinch the pushing and pulling part 22 with their fingers. By pushing and pulling the pushing and pulling part 22, the clamping member 2 is driven to move, and under the locking action of the tripping component 3, the object is clamped in cooperation with the connecting member 1.

[0028] Furthermore, it also includes a pair of transmission gears 32. The pair of transmission gears 32 are meshed with each other and rotatably connected within the connecting portion 12 through a rotating shaft. One of the transmission gears 32 is meshed with the tooth groove 31, and a ratchet wheel 33 is coaxially fixed to the shaft end of the other transmission gear 32.

[0029] More specifically, the ratchet wheel 33 is used in cooperation with a pawl 34. The pawl 34 is rotatably connected within the connecting portion 12, and a spring 35 is fixedly connected between the bottom of the pawl 34 and the inner wall of the connecting portion 12. The top of the pawl 34 also has a pressing portion 341.

[0030] In specific operation, the pawl 34 locks the ratchet wheel 33. The reason for the coaxial arrangement of the ratchet wheel 33 is to fix one of the transmission gears 32. When this transmission gear 32 is locked, the other transmission gear 32 is limited and fixed, so that the clamping member 2 cannot slide.

[0031] Then, by pressing the pawl 34 through the pressing portion 341, the pawl 34 is disengaged from the ratchet wheel 33, enabling the clamping member 2 to slide freely. Of course, a protective cover in an L-shaped structure can be provided at the top of the connecting portion 12. There is a gap between the protective cover and the pressing portion 341 to prevent locking, so as to reduce the probability of accidental touch.

[0032] Generally speaking, a relief groove 121 is provided at the top of the connecting portion 12, and the pressing portion 341 is movably connected within the relief groove 121.

[0033] It is worth mentioning that on the one hand, the relief groove 121 provides a moving space for the pressing portion 341, and on the other hand, the relief groove 121 abuts against the side of the pressing portion 341 close to the spring 34 to limit the pawl 34.

[0034] Finally, the lower clamping plate 21 is composed of a clamping plate 211 and a threaded rod 212. The clamping plate 21 is parallel to the upper clamping plate 11, and clamping mouth grooves 213 are provided on both sides thereof. The threaded rod 212 is fixedly connected to the clamping plate 211 at the top and is threadedly connected to the clamping member 2 at the bottom.

[0035] Working mode; during work, the opening of the connecting member 1 is set on the object to be clamped. The clamping member 2 is pushed to move through the pushing and pulling portion 22, and the object is clamped by the upper clamping plate 11 and the lower clamping plate 21. Moreover, because of the single-direction rotation characteristic between the ratchet wheel 33 and the pawl 34, when meshed, the clamping member 2 can be prevented from moving and resetting by fixing the transmission gear 32.

[0036] Then, tools such as a wrench can be used to rotate the threaded rod 212 by means of the bayonet slot 213. The threaded rod 212 is threadedly connected to the clamping member 2 to drive the clamping plate 211 to move up and down, so as to ensure that the upper and lower clamping plates can clamp or unlock the membrane shell and the steel reinforcement cage.

[0037] The ratchet pawl 34 can be disengaged from the ratchet wheel 33 by pressing the pressing portion 341. The ratchet wheel 33 that loses the locking function rotates following the transmission gear 32, and then the clamping member 2 is pulled through the pushing and pulling portion 22 to perform a tripping reset.

[0038] The above is only a 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 of the present invention and its inventive concept, makes an equivalent substitution or change, and should be covered by the protection scope of the present invention.
