Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a snap-type bolt. Background Art

[0002] This snap-type bolt is developed to solve the problems of difficult disassembly, time-consuming and laborious in the construction process of full casing. The original connection method of the casing is thread tightening. Sometimes, thread damage will cause difficulty in disassembly. Moreover, concrete slurry and the like are easy to penetrate into the thread and solidify, resulting in the bolt being unable to be screwed in or difficult to be screwed in. If the disassembly time of the bolt is too long, the concrete will solidify, resulting in the casing being unable to be pulled out, causing heavy losses. However, the snap-type bolt does not have such problems. Content of the Utility Model
