Problems solved by technology
This connection and fastening method is simple in structure, easy to operate, and good in load capacity, but it is only suitable for fastened parts that can be threaded. In reality, some fastened parts can only make light holes without threads, so this method cannot Bolt and nut connection fastening method for fastening installation
Even if it is installed, it is easy to loose the thread, resulting in the failure of the fastener to be fastened
When fastening, it is generally necessary to be equipped with special tools, otherwise it will be difficult to achieve installation, which will bring certain troubles to the staff.

Embodiment Construction
[0017] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0018] Such as Figure 1 to Figure 5 A fastener shown includes an inner connector 1 and an outer connector 2. The inner connector 1 includes an inner rod 11 and a block 12 integrally formed with the inner rod 11 and arranged at the top end of the inner rod. The opposite ends of the block 12 are A movable block 13 is movable, and the outer connecting piece 2 includes an outer rod 21 and a limiting portion 22 at the top of the outer rod. The inner connecting piece 1 and the outer connecting piece 2 are connected by threads.
[0019] The outer surface of the inner rod 11 is provided with an external thread 111, and the inner shaft of the outer rod 2...

The invention relates to a fastener, which includes an inner connecting piece and an outer connecting piece. The inner connecting piece includes an inner rod and a block integrally formed with the inner rod and arranged at the top of the inner rod. Both ends of the block are provided with movable blocks. The connecting piece includes the outer rod and the limiting part at the top of the outer rod. The inner connecting piece and the outer connecting piece are connected by threads. One end of the movable block is provided with an extending rod, and the outer ring of the end of the extending rod is provided with a telescopic part. There is a groove for containing the telescopic part inside, and the telescopic part includes a protrusion provided on the extension rod and a protrusion groove matched with the protrusion, and the protrusion and the protrusion groove are connected by an elastic member. After adopting the above structure, through the disassembly of the movable blocks on both sides of the box, it is convenient for the staff to use the box itself to tighten the fasteners without using tools; The support and limit function of the inner rod prevents the inner rod from detaching from the outer rod during the vibration process.
Description
technical field [0001] The invention relates to the field of assembly technology, in particular to a fastener. Background technique [0002] At present, when connecting metal or non-metal materials, bolts or screws are mostly used. When connecting and fastening components, workers need to work on both sides of the component at the same time, that is, insert bolts with nuts on one side, and then use tools to tighten the nuts on the other side. This connection and fastening method is simple in structure, easy to operate, and good in load capacity, but it is only suitable for fastened parts that can be threaded. In reality, some fastened parts can only make light holes without threads, so this method cannot Bolt and nut connection fastening method for fastening installation. Even if it is installed, it is easy to loose the thread, resulting in the failure of the fastener to be fastened. When fastening, it is generally necessary to be equipped with special tools, otherwise it...
