[0036] Preferably, when binding the goods, both ends of the safety block 9 are engaged in the tooth grooves of the left gear 3 and the right gear 4.

[0037] Preferably, the pull block 19 is provided with two inclined surfaces 26, and the pull block 19 slides within two sliding grooves 18 via the two inclined surfaces 26. When the pull block 19 is pulled upward, the inclined surfaces 26 at both ends facilitate pushing the right support spring plate 15 and the left support spring plate 14 outward to the left and right ends.

[0038] Preferably, the left support spring plate 14 and the right support spring plate 15 can be deformed by pulling the left support 11 and the right support 12 of the handle outward.

[0039] When installing or removing the adjustment device, the left support spring plate 14 or the right support spring plate 15 can be moved towards the center or to both sides, so that the left support spring plate 14 or the right support spring plate 15 can be installed or separated from the shaft core 2.

[0040] Preferably, the front ends of the left handle bracket 11 and the right handle bracket 12 are provided with semi-circular slots 22, and the left handle bracket 11 and the right handle bracket 12 are engaged with the two ends of the shaft core 2 through the semi-circular slots 22.

[0041] When installing or removing the adjustment device, the semi-circular slot on the left support 11 or the right support 12 of the handle can be installed or removed from the shaft core 2.

[0042] Preferably, a handle core 23 is provided between the rear ends of the left handle bracket 11 and the right handle bracket 12. The two ends of the handle core 23 are respectively connected to the left handle bracket 11 and the right handle bracket 12 through rubber plugs 24. A handle cover 25 is provided on the handle core 23.

[0043] The assembly steps for the tensioning device are as follows:

[0044] First, the left gear 3 and the right gear 4 are respectively assembled at the left and right ends of the shaft core 2, and then assembled into the main body 1. Elastic retaining rings 5 ​​are assembled at both ends.

[0045] Second, bolt 6 is assembled onto the head of body 1, and then anti-loosening nut 7 is assembled to prevent bolt 6 from falling off.

[0046] Third, the safety block spring 10 is assembled to the head of the safety block 9, and then the whole assembly is assembled into the lower end of the main body 1.

[0047] The assembly steps for the adjustment device are as follows:

[0048] First, the handle core 23 is assembled into the handle cover 25, and then rubber plugs 24 are installed on both the left and right ends to fix it.

[0049] Second, the upper ends of the right bracket spring plate 15 and the left bracket spring plate 14 are respectively riveted to the right bracket 12 and the left bracket 11 of the handle with rivets 13.

[0050] Third, after the pull block 19 is assembled with the pull block spring 21, it is mounted on the assembly of the left handle bracket 11 and the right handle bracket 12.

[0051] Fourth, pins A16 and B17 are respectively fixed on the assembly of the left handle bracket 11 and the right handle bracket 12.

[0052] Working principle:

[0053] First, pull up by the pull block 19. Because of the action of the inclined surfaces 26 at both ends of the pull block 19, it is convenient to push the right support spring plate 15 and the left support spring plate 14 outward to the left and right. Since the uppermost ends of the right support spring plate 15 and the left support spring plate 14 are fixed to the right support 12 and the left support 11 of the handle by the rivet 13, the right support spring plate 15 and the left support spring plate 14 can only open outward by using the rivet 13 as the rotation center point.

[0054] Second, by using the shape of the semi-circular hook at the lower end of the handle left bracket 11 and handle right bracket 12, the left and right ends of the shaft core 2 of the main body 1 are hooked. The round holes at the lower end of the right bracket spring plate 15 and left bracket spring plate 14 are fitted into the left and right ends of the shaft core 2 of the main body 1. At this time, the handle part and the main body 1 part are completely connected together.

[0055] Third, by rotating the handle sleeve 25 and other components on the handle part upward and downward, the shaft core 2 can be rotated. Because the rotation of the shaft core 2 can simultaneously drive the left gear 3 and the right gear 4 to rotate, the webbing can be moved to retract or extend.

[0056] Fourth, once the required webbing binding is achieved, the handle is no longer needed. At this point, simply push the pull block 19 on the handle part, and the right bracket spring plate 15 and the left bracket spring plate 14 will disengage from the shaft core 2. The right bracket 12 of the handle and the elastic retaining ring 5 can then be removed from the shaft core 2, making it easy to detach the handle part from the main body 1.

[0057] It should be noted that the two ends of the webbing are connected between the shaft core 2 and the bolt 6, respectively. By turning the bolt 6, the webbing is continuously tightened or loosened, thereby achieving the binding of the goods.

[0058] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
