[0022] In the above technical solution, considering that different workpieces need to be produced, the hydraulic cylinder needs to perform different stroke stamping, and there may be a problem of insufficient stroke, which affects the production efficiency. In order to solve such problems, the specific operations are as follows:
[0023] Reference Figure 1 - Figure 4 In a preferred embodiment, the output end of the motor 4 drives the bidirectional screw rod 501 to rotate, and then the two moving blocks 503 move towards each other, and then the two adjusting rods 504 extend downward, and the bottoms of the two adjusting rods 504 rotate inside the rotating block 505, so that the hydraulic cylinder body 1 is adjusted downward. After the adjustment is completed, the staff turns off the motor 4 and then starts the hydraulic cylinder body 1. The output shaft 2 extends downward from the inside of the hydraulic cylinder body 1. Through the set adjustment mechanism, the stroke adjustment of the hydraulic cylinder body 1 is realized, and the stroke of the hydraulic cylinder body 1 can be increased to meet different production needs.
