[0002] Building line setting-out is to facilitate the work of workers and to be able to construct strictly according to the design drawings. Generally speaking, all building axes can be called major lines, and the corresponding minor lines are the side lines and dimension lines of structural components. The main idea of line setting-out is to transfer the dimensions of the design drawings to the ground according to the illustrated dimensions. Whether the dimensions of the entire project are constructed according to the design drawing dimensions depends on the technical content of line setting-out. In addition, line setting-out is for all construction to have a dimension basis. The steel bar workers should tie the steel bars based on the line to find the position, the carpenters should support the formwork based on the line, and the bricklayers should build the wall based on the line.

[0003] In addition, during the construction operation process of a building, when carrying out construction line setting-out, the operator will use a special line setting-out device for line setting-out. However, in the existing line setting-out operation process, the wire inside the line setting-out device usually lacks the positioning and clamping of the wire spool. Therefore, it is relatively troublesome to keep the wire straight during line setting-out. For this reason, a line setting-out device needs to be designed. Content of the Utility Model

[0025] The present utility model provides the following technical solutions:

[0026] Embodiment 1

[0027] Combined with Figures 2 to 5 , a wire pay-off device includes a mobile vehicle 1, a retracting and extending mechanism 2 is fixedly connected to the left end of the top of the mobile vehicle 1, and a clamping mechanism 3 is fixedly connected to the inside of the right end of the mobile vehicle 1;

[0028] The retracting and releasing mechanism 2 comprises an L-shaped frame 21, a first spring 22 is fixedly connected to the top of the L-shaped frame 21, a T-shaped long block 23 is fixedly connected to one end of the first spring 22, a connecting piece 24 is fixedly connected to the bottom end of the T-shaped long block 23, a clamping rod 25 is fixedly connected to the inside of the connecting piece 24, an L-shaped rod 26 is rotatably connected to one side of the connecting piece 24, an operating rod 29 is rotatably connected to the middle of the top of the mobile vehicle 1, an I-shaped cylinder 27 is fixedly connected to the lower surface of the operating rod 29, a positioning ring 28 is fixedly connected to the surface of the operating rod 29 near the top of the I-shaped cylinder 27, a guide groove is provided inside the top of the L-shaped frame 21, the surface of the T-shaped long block 23 is slidably connected to the inside of the guide groove, a positioning hole is provided on the surface of the positioning ring 28, and the surface of the clamping rod 25 passes through the positioning hole provided on the surface of the positioning ring 28.

[0029] Furthermore, a notch is provided on the left side of the L-shaped frame 21, and one end of the surface of the L-shaped rod 26 matches the inside of the notch. The clamping rod 25 moves and thereby disengages the clamping positioning function inside the positioning ring 28. At this time, one end of the L-shaped rod 26 is just located in the notch on the L-shaped frame 21. Then, the L-shaped rod 26 is rotated to drive one end thereof to be clamped in the notch position. Then, one end of the released wire passes through the clamping tube 34 and the release operation is performed. The operation is convenient, fast and easy to use, thereby facilitating the release and retraction operation of the construction wire. When rewinding the wire, the operating rod 29 can be rotated in the opposite direction to rewind the wire. Therefore, it is more convenient to keep the wire straight when releasing the wire, and it is convenient for the operator to perform the release operation.

[0030] Embodiment 2

[0031] See also Figures 1 - 5 On the basis of the first embodiment, the clamping mechanism 3 further comprises a second spring 31, the second spring 31 is fixedly connected to the inside of the right end of the moving vehicle 1, one end of the second spring 31 is fixedly connected to a slider 32, the top of the slider 32 is rotatably connected to a long rod 33, the lower surface of the long rod 33 is rotatably connected to a clamp 34, the upper surface of the long rod 33 is fixedly connected to a friction ring 35, a slide groove is provided at the top of the right end of the moving vehicle 1, and the surface of the slider 32 is slidably connected to the inside of the slide groove.

[0032] Furthermore, the lower surface of the friction ring 35 fits tightly with the top of the clamp 34. There are two clamps 34 and two friction rings 35. Since the wiring harness is located between the two clamps 34, it is tightly clamped by the elastic force of the second spring 31. In the process, the friction force between the long rod 33 and the top of the clamp 34 can increase the clamping force of the clamp 34 on the wiring harness, and the arbitrary rotation of the clamp 34 can be avoided as much as possible, so that the tension on the wiring harness can be maintained when winding the line.

[0033] In actual operation, when this device is used, during the process of laying out the wires for construction, when laying out the wires is needed, the connecting piece 24 is pulled open to drive the T-shaped long block 23 to move under the limit position inside the L-shaped frame 21, thereby driving the clamping rod 25 inside the connecting piece 24 to move and thereby disengage the clamping and positioning function inside the positioning ring 28, and at this time, one end of the L-shaped rod 26 is just located in the notch on the L-shaped frame 21, and then the L-shaped rod 26 is rotated to drive one end thereof to be clamped in the notch position, and then one end of the wire to be laid out passes through the clamping tube 34 and the wire laying operation is performed, and the operation is convenient, fast and easy to use, thereby facilitating the construction wire laying and retracting operation, and when reeling in the wires, the operating rod 29 is reversely rotated to reel in the wires;

[0034] In addition, when winding the line, since the wire harness is located between the two clamps 34, the elastic force of the second spring 31 is used to tightly clamp it. In the meantime, the friction between the long rod 33 and the top of the clamp 34 can increase the clamping force of the clamp 34 on the wire harness, and the arbitrary rotation of the clamp 34 can be avoided as much as possible, so that the tension on the wire harness can be maintained when winding the line.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
