Background
The existing extension shaft generally has two parts, a main body shape and an internal rotating shaft, and the product detection is carried out by internal rotation on special equipment.
The inventor finds that the existing extension shafts mostly adopt an integrated structure in daily work, which causes low precision, unstable operation, difficult processing, high cost, complicated internal structure and difficult maintenance, and the existing extension shafts need to be improved.
Disclosure of utility model
The utility model aims to solve the defects of low precision, unstable operation, difficult processing, high cost, excessively complex internal structure and difficult maintenance caused by the fact that the existing extension shaft in the prior art adopts an integrated structure.
In order to achieve the above purpose, the present utility model adopts the following technical scheme: the extension shaft comprises a main shaft, a first rotating shaft is rotatably connected to the inside of the main shaft, a second rotating shaft is rotatably connected to the inside of the main shaft, a first circular outer ring is arranged on the surface of the main shaft, and a second circular outer ring is arranged on the surface of the main shaft.
Preferably, the first rotating shaft is of a two-section design, so that the normal use of the device is facilitated.
Preferably, the second rotating shaft is hollow, wherein one section of the first rotating shaft is inserted into the second rotating shaft, and the application has the advantages of simple structure, reduced manufacturing cost, convenient installation, high assembly precision and stable operation.
Preferably, the first exhaust hole is formed in one end, located outside the main body shaft, of the first rotating shaft, so that equipment is convenient to install.
Preferably, a second exhaust hole is formed in one end, located outside the main body shaft, of the second rotating shaft, so that normal operation of the equipment is ensured.
Preferably, the inner wall of the second rotating shaft is rotatably connected with a steel ball.
Preferably, a positioning sleeve is mounted on the surface of the main body shaft, and the positioning sleeve is located between the first circular outer ring and the second circular outer ring.
Compared with the prior art, the utility model has the advantages and positive effects that:
1. In the utility model, the whole structure of the extension shaft is simplified, the complex part can adopt a combined welding process, the manufacturing finished product is reduced, the internal design is simplified, and the assembly and maintenance are more convenient.
2. The utility model has the advantages of simple structure, reduced manufacturing cost, convenient installation, high assembly precision and stable operation.
