After releasing, the pair of first clamping blocks 4121 can pop out in opposite directions under the action of the first elastic plate 4122, and a pair of clamping holes 4112 that are clamped with the pair of first clamping blocks 4121 are opened at the groove wall near the groove of the mounting groove 4111, and the clamping holes 4112 extend toward the bottom of the mounting groove 4111, so that the clamping column 412 can move back and forth toward the bottom of the mounting groove 4111 under the cooperation of the first clamping block 4121 and the clamping hole 4112.

[0040] Reference Figure 3 and Figure 4 A pair of second clamping blocks 4123 are integrally formed at one end of the clamping column 412 away from the first clamping block 4121, and the pair of second clamping blocks 4123 are arranged opposite to each other. The second clamping block 4123 is used to clamp with the lock hole 42, and a second elastic plate 4124 is integrally formed between the second clamping block 4123 and the clamping column 412. In order to facilitate the operator to clamp the second clamping block 4123 and the lock hole 42, a pulling column 4125 is integrally formed at one end of the second clamping block 4123 away from the second elastic plate 4124, so that the operator can pinch the pair of pulling columns 4125 to drive the pair of second clamping blocks 4123 to move in opposite directions. After releasing the pair of pulling columns 4125, the pair of second clamping blocks 4123 can pop out in opposite directions under the action of the second elastic plate 4124 and clamp with the lock hole 42.

[0041] Reference Figure 2 , Figure 3 and Figure 5 A waist-shaped groove 3211 is provided at the end face of the second protrusion 321 facing the first protrusion 231, and hinge protrusions 3212 are welded at the front and rear groove walls opposite to the waist-shaped groove 3211.

[0042] Reference Figure 3 , Figure 5 and Figure 6When the second clamping block 4123 is not engaged with the locking hole 42, in order to fix the connecting column 411 and the clamping column 412 to prevent them from rotating at will, an elastic clamping seat 312 is welded on the end surface of the second side plate 31 between the first protrusion 231 and the second protrusion 321. The elastic clamping seat 312 is in a "C" shape and is used to be engaged with the clamping column 412.

[0043] The implementation principle of the lifting belt equipped with an anti-slip fixing buckle in the embodiment of the present application is as follows: after the bolting belt 1 is tightened by the fastener 2 and the pulling member 3, the clamping column 412 is pulled out from the elastic clamping seat 312, the connecting column 411 is rotated so that the second clamping block 4123 is aligned with the locking hole 42, and the end of the clamping column 412 welded with the return spring 413 is pressed so that the second clamping block 4123 passes through the locking hole 42 and is clamped with the locking hole 42, thereby completing the locking between the fastener 2 and the pulling member 3;

[0044] When it is necessary to loosen the bolting belt 1, pinch the pulling column 4125 to make a pair of second clamping blocks 4123 move in opposite directions. At this time, the second clamping block 4123 is no longer engaged with the locking hole 42. Under the action of the reset spring 413, the second clamping block 4123 is pulled toward the bottom of the installation groove 4111. After the second clamping block 4123 is taken out of the locking hole 42, the connecting column 411 is rotated to clamp the clamping column 412 into the elastic clamping seat 312, so as to release the lock between the fastener 2 and the pulling member 3, thereby loosening the bolting belt 1.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
