Further technical scheme may be that the second positioning pair 9 includes a swing angle limiting block 91 and a second positioning arm 93, the swing angle limiting block 91 is disposed on the swing frame body 5, a hydraulic buffer 92 is disposed on the swing angle limiting block 91, the second positioning arm 93 matched with the hydraulic buffer 92 is disposed on the angle positioning plate 81, and when the swing frame body 5 swings reversely and tilts to a certain angle, the second positioning arm 93 can be combined with the hydraulic buffer 92 so as to enable the swing frame body 5 to be in a tilting position. Wherein the hydraulic damper 92 is a member that can cushion impact during collision and is advantageous for protecting the collision
In order to facilitate adjusting the swing angle of the swing frame body 5, the angle positioning plate 81 is provided with an arc-shaped through hole 810, the arc-shaped through hole 810 is arranged along the moving path of the swing angle limiting block 91, and the second positioning arm 93 is detachably arranged at different radian positions of the angle positioning plate 81 by means of the arc-shaped through hole 810. In order to firmly fix the second positioning arm 93 to the angle positioning plate 81, movement of the second positioning arm 93 when combined with the hydraulic buffer 92 is reduced, positioning notches 811 are arranged on the arc-shaped through holes 810 of the angle positioning plate 81 at intervals, and the second positioning arm 93 is mounted on the positioning notches 811, so that the second positioning arm 93 is firmly connected to the angle positioning plate 81, and the accuracy of angle positioning is greatly improved.
Further, in order to prevent the swing frame 5 from being damaged by collision with other members due to an excessive rotation angle, the cutting unit further includes a third positioning pair 6b, the third positioning pair 6b includes a third positioning block 64, and the third positioning block 64 is disposed on the auxiliary connection member and below the first positioning block 62; the third positioning block 64 is also a positioning nut (i.e. a second positioning nut), the auxiliary connecting piece is provided with a second positioning screw hole, the second positioning screw hole is arranged below the first positioning screw hole, and the third positioning block 64 is connected in the second positioning screw hole through threads; the third positioning pair 6b further includes a second claw 65, which is another claw disposed on the first positioning arm 61, and when the first positioning arm 61 rotates from the vertical cutting position to the inclined cutting position, the second claw 65 also rotates, and when the swing frame 5 swings at the limit swing position in the swing direction, the second claw 65 and the third positioning block 64 are combined to block the swing frame 5 from continuing to rotate, thereby solving the risk of collision between the swing frame 5 and other components and improving the safety of the cutting unit.
