Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which are obtained by a worker of ordinary skill in the art without creative efforts, are within the protection scope of the present utility model based on the embodiments of the present utility model.

Referring to fig. 1 to 3, the present utility model provides a technical solution: the utility model provides an antidetonation type nut, includes main nut 1, the inside fixedly connected with spring 2 of main nut 1, the one end fixedly connected with buckle 3 of spring 2, one side swing joint of buckle 3 has bolt ring 4, the bottom fixedly connected with anticreep nut 5 of bolt ring 4.

In this embodiment, as shown in fig. 2, a clamping groove matched with the latch ring 4 is formed at the bottom of the main nut 1; it should be noted that, the bottom of the main nut 1 is provided with the clamping groove adapted to the latch ring 4, so that the latch ring 4 can be inserted into the clamping groove, thereby the main nut 1 and the anti-falling nut 5 form a whole, and the fastening component is fixed to avoid falling off due to vibration.
