Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1, 2 and 3, the present invention provides a high strength bucket shaft, which comprises: the structure of the device comprises a shaft body 1, wherein one end of the shaft body 1 is provided with a positioning plate 2, the positioning plate 2 is provided with two assembling holes 3 at intervals, one assembling hole 3 is tightly and fixedly sleeved with the shaft body 1, the assembling hole 3 and the inner wall of the bottom are provided with a limiting ring 4, the outer wall of the end part of the shaft body 1 is provided with a limiting groove 5 nested with the limiting ring 4, a reinforcing structure is arranged between the two assembling holes 3 and comprises a limiting rod 6, an L-shaped sliding groove 7 and a limiting bolt 9, one end of the L-shaped sliding groove 7 penetrates out of the upper end surface of the positioning plate 2, the other end of the L-shaped sliding groove 7 is communicated with the assembling hole 3, the limiting rod 6 is arranged in the L-shaped sliding groove 7 in a sliding manner, the end part of the limiting rod 6 is embedded in the outer wall of the shaft body 1, the limiting bolt 9 is matched with the L-shaped sliding groove 7 from the upper end surface of the positioning plate 2 and is in threaded connection with the limiting rod 6, when the limiting bolt 9 is screwed, the top of the limiting bolt 9 is tightly contacted with the upper end surface of the positioning plate 2, the outer wall of the shaft body 1 is provided with an annular clamping groove 8 which is nested with the limiting rod 6, the end face, contacting with the annular clamping groove 8, of the limiting rod 6 is provided with an arc-shaped notch 10, the limiting ring 4 and the positioning plate 2 are integrated, and a gap is formed between one end, away from the shaft body 1, of the limiting rod 6 and the inner wall of the L-shaped sliding groove 7.
