[0022] The present invention is further described below through specific implementation methods.

[0023] like Figures 1 to 3 As shown, a reusable fixing device described in the utility model includes a fixing rod body 1 and a locking mechanism 2, wherein the fixing rod body 1 is provided with a threading hole 11, the locking mechanism 2 is arranged at one end of the fixing rod body 1 and is used to lock and fix the cable 4 in the threading hole 11, and a notch 12 is provided on the outer peripheral surface of the other end of the fixing rod body 1 to allow the cable 4 to be bent and pass through.

[0024] The locking mechanism 2 is used to lock and fix the cable 4 that passes through the threading hole 11 of the fixed rod body 1, which can effectively ensure the stability and reliability of the connection between the cable 4 and the fixed rod body 1, and no additional pressing tool is needed to press the fixed rod body 1 and the cable 4 to press the cable 4. At the same time, the fixing device can be reused. The notch 12 is set to allow the cable 4 to be bent and pass through the notch 12, so that the fixed rod body 1 can be inserted into the column 3 through the mounting hole 31 on the single side surface of the column 3. The fixing device can be stuck in the inner cavity of the column 3, and the length of the fixing device is greater than the width of the mounting hole 31, that is, the length of the fixing rod body 1 is greater than the width or inner diameter of the mounting hole 31, and the fixing device can be completely hidden in the column 3, so that only the tightened cable 4 can be seen between the columns 3, so as to improve the overall aesthetics. In this way, the cable 4 can be fixed from the single-side hole position of the column 3, and then a single-pile corner can be realized at the corner. In addition, it can also be well adapted to the use of inclined stair scenes and horizontal scenes.

[0025] Preferably, the cable 4 is a steel wire rope or a cable 4 made of other materials.

[0026] The locking mechanism 2 includes at least one locking screw 21, and at least one locking hole 22 communicating with the threading hole 11 is provided on the outer circumferential surface of one end of the fixed rod body 1. The locking screw 21 is detachably threadedly connected to the locking hole 22. Preferably, there are three locking holes 22. In other embodiments, the number of the locking holes 22 may also be 1, 2 or 4. The three locking holes 22 are arranged at intervals along the circumference of the fixed rod body 1, and two adjacent locking holes 22 are arranged 180 degrees apart from each other along the circumference of the fixed rod body 1. The distances from the three locking holes 22 to the end of the fixed rod body 1 are increased successively, and the spacing between two adjacent locking holes 22 is equal. Therefore, when one end of the cable 4 is inserted into the threading hole 11 of the fixed rod body 1, the three locking screws 21 can be tightened in the corresponding locking holes 22 respectively, and the cable 4 is squeezed, and the cable 4 passed through the threading hole 11 is made into an S shape to ensure its locking and fixing effect, thereby ensuring the stability and reliability of the connection between the fixed rod body 1 and the cable 4.

[0027] Preferably, the locking screw 21 is of a hexagonal head type, so that the thread slipping problem is less likely to occur when the locking screw 21 is disassembled and assembled.

[0028] In addition, the slot 12 and any one of the locking holes 22 are arranged at 90 degrees to each other along the circumference of the fixed rod body 1, and the slot 12 is in a strip shape. The width of the slot 12 is consistent with the inner diameter of the threading hole 11, and one end of the slot 12 passes through an end face of the fixed rod body 1, and the other end of the slot 12 can extend to near the locking mechanism 2. The other end of the slot 12 is arranged in the middle of the fixed rod body 1. In this way, the cable 4 can be bent and passed through the middle of the fixed rod body 1, which is beneficial to improve the stability of the fixed rod body 1 when it is clamped in the column 3, and is also beneficial to the fixing and clamping of the cable 4.

[0029] In addition, the threading hole 11 passes through both ends of the fixing rod body 1 .

[0030] A guardrail comprises a cable 4, at least two posts 3 and at least two reusable fixing devices described in any one of the above items, at least one mounting hole 31 is provided on both side end faces of the posts 3, both ends of the cable 4 are respectively connected to the two reusable fixing devices, the reusable fixing devices pass through the mounting holes 31 of the posts 3 on the corresponding side and are installed in the posts 3 and tighten the cable 4, and the fixing device can bend the cable using a notch 12 according to different angles between the two posts 3.

[0031] The method of using the reusable fixing device and the guardrail thereof described in the utility model is as follows:

[0032] Pass one end of the cable 4 through the threading hole 11 from the side of the fixed rod body 1 where the notch 12 is provided;

[0033] Use the locking screw 21 to tighten into the corresponding locking hole 22 on the fixing rod body 1 to lock and fix one end of the cable 4;

[0034] Use two pliers to clamp the fixed rod body 1 and the cable 4 respectively, and bend and twist the cable 4 and pass it through the notch 12 of the fixed rod body 1;

[0035] Insert the fixing rod 1 and the cable 4 into the column 3 from the mounting hole 31 on the single side surface of the column 3 , and make the fixing rod 1 stuck in the inner cavity of the column 3 , and let the cable 4 pass through the mounting hole 31 .

[0036] It should be understood that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made and that such a development effort may be complex and time-consuming, but will be a routine task of design, manufacturing, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0037] The above are only some specific implementation methods of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
