[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-8 .

[0033] To address the problems in existing technologies where the lengths of the components forming the fence vary, making it inconvenient to provide stable support based on the length of the components, and where the large size of the device results in a large footprint and inconvenience for storage and transport after use, this solution provides a portable fence construction positioning device. This device includes a base plate 1 for support, a lower clamping plate 10 and an upper clamping plate 11 for holding the fence components, adjustable movable columns 3 slidably connected to the left and right ends of the base plate 1, and movable blocks 4 fixedly connected to the front and rear ends of the movable columns 3. A support plate 9 is hinged to the middle of the movable columns 3, and the support plate 9 drives the lower clamping plate 10 and the upper clamping plate 11 to form a flipping structure at the upper end of the base plate 1. A torsion spring is also provided at the connection between the support plate 9 and the movable columns 3.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, place the base plate 1 in an appropriate position. Then, according to the length of the fence workpiece, pull the fixed rod 8 upward. The fixed rod 8 drives the movable bracket 5 to move upward. The movable bracket 5 slides in the movable block 4 and compresses the spring 6, causing the spring 6 to undergo elastic deformation. The upper end of the movable bracket 5 disengages from the protrusion 7, thereby releasing the restriction between the movable block 4 and the base plate 1. Then, pull the movable column 3 to the left or right. The movable column 3 drives the movable block 4 to slide left and right between the base plate 1, which facilitates the adjustment of the spacing between the movable columns 3 at the left and right ends of the base plate 1. This allows for the support and positioning of fence workpieces of different lengths. After adjustment, release the fixed rod 8 directly. At this time, the spring 6 returns to its elastic deformation, causing the movable bracket 5 to move downward, so that the upper end of the movable bracket 5 engages with the protrusion 7 at the corresponding position, thus limiting the restriction between the movable block 4 and the base plate 1.

[0035] After adjustment, as follows Figure 1 and Figure 5As shown, the workpiece that makes up the fence is placed in the middle of the lower clamping plate 10, and then the upper clamping plate 11 is flipped down. The upper clamping plate 11 rotates with the lower clamping plate 10 to clamp and position the fence workpiece. At the same time, the upper clamping plate 11 drives the connecting rod 12 to connect downward with the rear end slot of the lower clamping plate 10. Then, the connecting cap 13 threaded to the outer surface of the connecting rod 12 is rotated. The connecting cap 13 moves upward and fits against the lower clamping plate 10, which facilitates the limiting of the connection between the connecting rod 12 and the lower clamping plate 10. The upper clamping plate 11 is fixed at the upper end of the lower clamping plate 10, completing the clamping and positioning of the fence workpiece. Then, the fence workpiece can be assembled and spliced.

[0036] After use, such as Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, first, the movable column 3 is moved closer to the vertical central axis of the base plate 1. Then, the fixing bolt 16 is rotated, disengaging the fixing bolt 16 from the fixing frame 15, thereby releasing the restriction between the fixing frame 15 and the movable column 3. Then, the fixing frame 15 is flipped, rotating inside the movable column 3, disengaging the fixing frame 15 from the movable block 4, thereby releasing the restriction between the support plate 9 and the movable column 3. At this time, the torsion spring at the connection between the support plate 9 and the movable column 3, which was originally in an elastic deformation state, returns to its elastic deformation, causing the support plate 9 to flip outward. The support plate 9 then causes the lower clamping plate 10 and the upper clamping plate 11 to flip downward until they are in the position shown. Figure 8 In the state shown, the support plate 9 drives the fixing block 14 to detach from the movable column 3, which makes it easy to flip and store the device. Then, the device can be carried by holding the fixing rings 2 fixed at the front and rear ends of the middle of the base plate 1, which improves the portability of the device.

[0037] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
