[0024] The specific implementation process of this utility model is as follows: When it is necessary to adjust the distance between the two cutting frames 5, pull the pull ring seat 72. The pull ring seat 72 drives the steel wire 71 to move. During the movement, the steel wire 71 drives the positioning seat 8 to move through the guide frame 9 and compresses the first spring 11. At the same time, the steel wire 71 compresses the second spring 75 through the connecting plate 73. When the positioning seat 8 is disengaged from the current positioning groove 6, the limit on the guide bar 4 can be released. Then the position of the cutting frame 5 is adjusted. After the adjustment is completed, release the pull ring seat 72. The first spring 11 returns to its original position. The first spring 11 can drive the positioning seat 8 to slide into the adjusted positioning groove 6 through its elasticity. This completes the adjustment of the distance between the two saw blades 16, making the cutting distance easier to adjust.
