The reference numbers illustrate: 1. a base iron sheet; 11. a gap bridge position; 12. a raised elastic sheet; 2. a spring; 21. a first reverse buckle; 22. and (6) a second reverse buckle.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. This application is capable of being embodied in many different forms and is not limited to the embodiments described in this specific example. The following detailed description is provided to facilitate a more thorough understanding of the present disclosure, and the words used to indicate orientation, top, bottom, left, right, etc. are used solely to describe the illustrated structure in connection with the accompanying figures.

Please refer to fig. 2, the utility model discloses a connection structure of spring and iron sheet, including base iron sheet 1 and spring 2, base iron sheet 1 is equipped with three gap bridge position 11, three gap bridge position 11 is the T font on base iron sheet 1, after the gap bridge position 11 of base iron sheet 1 was passed to the one end of spring 2, set up first back-off 21 at the end of spring 2, the other end of spring 2 sets up second back-off 22, first back-off 21 and second back-off 22's position are on same vertical side.

Compared with the prior art, the three gap bridge positions 11 are adopted to replace the traditional two gap bridge positions, the linear structure on the base iron sheet 1 is changed into a T-shaped structure, the clamping stability of the spring 2 and the base iron sheet 1 is improved, and the drawing force between the spring 2 and the base iron sheet 1 is also improved; the first reverse buckle 21 and the second reverse buckle 22 are respectively arranged at the tail end of the spring 2, and the reverse buckles at the two ends of the spring 2 are arranged on the same vertical side face, so that the drawing force between the spring and the base iron sheet 1 can be further improved; wherein spring 2 is used for improving the steadiness with 1 joint of base iron sheet with the increase drawing force with the terminal first back-off 21 knot of base iron sheet, and the second back-off 22 of the spring 2 other end can prevent to cut the hand.
