Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

In fig. 1, a high-speed impact cylinder of a sleeve cylinder structure having an energy accumulating function includes a first chamber 21, a second chamber 31, and a third chamber 41.

The first chamber 21 is formed by enclosing an energy storage cylinder 2, an upper fixed disc 7, an inner cylinder 1 and a lower fixed disc 8 in sequence. The first chamber 21 is the area between the energy storage cylinder 2 and the inner cylinder 1. The inner cylinder 1 is disposed within the accumulator cylinder 2. The two ends of the inner cylinder 1 and the energy storage cylinder 2 are respectively abutted to the upper fixing disc 7 and the lower fixing disc 8, the two ends of the inner cylinder 1 are respectively connected with the upper fixing disc 7 and the lower fixing disc 8 through bolts, and the two ends of the energy storage cylinder 2 are respectively connected with the upper fixing disc 7 and the lower fixing disc 8 through bolts. A piston 3 is arranged in the inner cylinder 1, the piston 3 divides the inner cylinder 1 into a second chamber 31 and a third chamber 41, and the second chamber 31 is close to the lower fixed disk 8. The air supply enters the second chamber 31 through the first chamber 21 and the second chamber 31 pushes the piston 3 compressing the third chamber 41.
