It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0025] like Figure 1 As shown, a fixing device provided in this embodiment includes a first clamping plate 1, a second clamping plate 2, a clamping cavity 3, a latch plate 4, a first elbow 5, a second elbow 6, a fastener 7 and a nut 8. One end of the first clamping plate 1 is covered with the second clamping plate 2 to form the clamping cavity 3, and the other end of the first clamping plate 1 is provided with a first elbow 5 and a second elbow 6, the first elbow 5 is bent in a direction close to the second clamping plate 2 to form a first clamping cavity 51, and the second elbow 6 is bent in a direction away from the second clamping plate 2 to form a second clamping cavity 61.

[0026] like Figure 1 , Figure 2 As shown, the first clamping plate 1 comprises a first flat plate 11, a first bent plate 12 and a second flat plate 13 arranged in sequence, the first flat plate 11 is provided with a first hole 14, and the second flat plate 13 is provided with a second hole 15 and a third hole 16. The first hole 14 is a rectangular hole extending in the width direction and has a length L1. The second hole 15 is a round hole for the fastener 7 to pass through. The third hole 16 is a rectangular hole extending in the length direction and is used to insert the latch piece 4.

[0027] The first elbow 5 and the second elbow 6 are connected to the second flat plate 13, and the first elbow 5 and the second flat plate 13, and the second elbow 6 and the second flat plate 13 can be designed as an integrated structure. The first elbow 5 and the second elbow 6 are both U-shaped bends, so that the first clamping cavity 51 and the second clamping cavity 61 are both U-shaped. The third hole 16 is arranged close to the first elbow 5 and the second elbow 6.

[0028] like Figure 3 As shown, the second clamping plate 2 includes a second curved plate 21 and a third flat plate 22 connected to one end of the second curved plate 21. The end of the third flat plate 22 away from the second curved plate 21 is provided with a slot 25. The slot 25 is a U-shaped slot with an open end. The end of the slot 25 away from the third flat plate 22 is provided with an inclined plate 23 inclined upward. Figure 1 As shown, the fastener 7 is a bolt, the bolt head of which is placed at the lower end of the first clamping plate 1, and the screw is inserted into the second hole 15 and the slot 25 and then fastened by the nut 8 to clamp the protective rod 9 (such as Figure 4 The inclined plate 23 forms an anti-slip angle of the nut 8.

[0029] The first curved plate 12 is a downward curved plate, and the second curved plate 21 is an upward curved plate. When the two are butted together, the clamping cavity 3 is circular.

[0030] like Figure 1 , Figure 3 As shown, a tenon 24 is provided at one end of the second bent plate 21 away from the third flat plate 22. The tenon 24 includes a rod 241 connected to the second bent plate 21, and a head 242 connected to the rod 241. The head 242 and the rod 241 form a T-shaped structure. The rod 241 is loosely assembled in the first hole 14, so that the second clamping plate 2 can rotate a certain angle along the loosely fitted rod 241 to open or close the clamping cavity 3. The extension length L of the head 242 is greater than the extension length L1 of the first hole 14, so that the head 242 is placed at the lower end of the first flat plate 11. If the first hole 14 is a circular hole, L is greater than the diameter of the circular hole. The limiting effect of the head 242 prevents the second clamping plate 2 from being separated from the first clamping plate 1 after disassembly, thereby avoiding the loss of parts during the next use.

[0031] like Figure 1 As shown, the latch piece 4 is a wedge-shaped piece. The large end of the wedge-shaped piece is arranged close to one side of the second clamping plate 2.

[0032] like Figure 4As shown, the utility model also provides a tool-type protection system, including a protection rod 9, an upper mesh frame 10 and a lower mesh frame 20 arranged beside the protection rod 9, and the above-mentioned fixing device. The upper mesh frame 10 and the lower mesh frame 20 are arranged at intervals in the upper and lower parts. The first bent plate 12 is placed at the bottom of the protection rod 9, and the second bent plate 21 is placed at the top of the protection rod 9. When the nut 8 on the fastener 7 is tightened, the protection rod 9 is locked in the clamping cavity 3. The first elbow 5 and the second elbow 6 pass through the gap between the upper mesh frame 10 and the lower mesh frame 20, respectively, so that the first elbow 5 is clamped with the bottom of the upper mesh frame 10 on the side away from the protection rod 9, so that the bottom of the upper mesh frame 10 is clamped in the first clamping cavity 51; the second elbow 6 is clamped with the top of the lower mesh frame 20 on the side away from the protection rod 9, so that the top of the lower mesh frame 20 is clamped in the second clamping cavity 61. After the above installation is completed, the latch piece 4 is inserted into the third hole 16, so that the upper end of the latch piece 4 abuts against the inner side of the upper mesh frame 10, and the lower end of the latch piece 4 abuts against the inner side of the lower mesh frame 20, and the inner side is the side close to the protective rod 9. The mesh frame is locked by the joint action of the latch piece 4 and the elbow.

[0033] To prevent the latch piece 4 from falling, the wedge-shaped large end is arranged upward. And the wedge-shaped latch piece 4 can be clamped in the third hole 16 from top to bottom. The inner wall of one side of the third hole 16 can be arranged as an inclined wall adapted to the inclined surface of the wedge to increase the locking area.

[0034] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
