Since the outer diameter of the nail body 402 is larger than the outer diameter of the driving post 404 and the hole diameter of the moving block through hole 701, when the fastening screw 4 moves downward, the moving block 7 is pressed to move downward. At this time, the moving block 7 applies forces obliquely from both sides and downward to the lower end of the first latch 1 through the link 5. Because the upper end of the first fixture block 1 is rotatably connected to the base 6, the first fixture block 1 cannot move downward relative to the base 6, and can only move to both sides, so that the first slot portions 105 of the two first fixture blocks 1 move away from each other. The user then places the device on the bar so that the first slot portion 105 is positioned opposite the outer wall of the bar. And finally, the fastening screw 4 is rotated reversely, under the limiting action of the clamp spring 8, the fastening screw 4 pulls the moving block 7 to move upwards, so that the first clamping groove part 105 of the first clamping block 1 is driven to move oppositely, and then the first clamping groove part is clamped on the outer wall of the bar material, and fixation is completed. The reverse operation releases the fixing of the device on the bar.

Example 3

A fixing device for a rod, as shown in fig. 5 and 6, comprising: the first fixture block 1 and the connecting device are symmetrically arranged.

The first cartridge 1 includes: a first clamping groove part 105 with an inner concave cambered surface matched with the shape of the rod and a first transmission part 106 fixedly or integrally connected with the first clamping groove part 105.

Since the outer diameter of the nail body 402 is larger than the outer diameter of the driving post 404 and the hole diameter of the moving block through hole 701, when the fastening screw 4 moves downward, the moving block 7 is pressed to move downward. At this time, the moving block 7 applies a downward force to the upper end of the first latch 1. Because the lower end of the first fixture block 1 is rotatably connected with the base 6 through the connecting rod 5, the first fixture block 1 cannot move downwards relative to the base 6, and can only move towards two sides under the limiting action of the connecting rod 5, so that the first slot portions 105 of the two first fixture blocks 1 move back to back. The user then places the device on the bar so that the first slot portion 105 is positioned opposite the outer wall of the bar. And finally, the fastening screw 4 is rotated reversely, under the limiting action of the clamp spring 8, the fastening screw 4 pulls the moving block 7 to move upwards, so that the first clamping groove part 105 of the first clamping block 1 is driven to move oppositely, and then the first clamping groove part is clamped on the outer wall of the bar material, and fixation is completed. The reverse operation releases the fixing of the device on the bar.
