However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0014] As Figure 1 - Figure 2 shown, an iron chain tensioning device for tensioning an iron chain includes a screw 10, a first fixed claw device 20 and a second fixed claw device 30. The first fixed claw device 20 and the second fixed claw device 30 are sleeved on the screw 10. The screw 10 drives the first fixed claw device 20 and the second fixed claw device 30 to move closer to the center position of the screw 10 or away from both ends of the screw 10 by rotation.
[0015] In one embodiment, the first fixed claw device 20 includes a first rotating part 210 and a first claw part 220. The first claw part 220 is arranged on the first rotating part 210. The first rotating part 210 is provided with a first threaded hole 211. The first rotating part 210 is sleeved on the screw rod 10 through the first threaded hole 211, and the first rotating part 210 moves back and forth on the screw rod 10. For example, by providing the first threaded hole 211 on the first rotating part 210, the first rotating part 210 is sleeved on the screw rod 10 through the first threaded hole 211, which facilitates pushing the first rotating part 210 to move back and forth on the screw rod 10 by rotating the screw rod 10.
[0016] In one embodiment, the second fixed claw device 30 includes a second rotating part 310 and a second claw part 320. The second claw part 320 is arranged on the second rotating part 310. The second rotating part 310 is provided with a second threaded hole.
