The locking column 206 is fixedly connected to the outer wall of the slider 205 and is located on the outer wall of the slider 205 away from the threaded column 203.

[0026] The threaded tube 202 is threadedly connected to the threaded column 203, and the threaded column 203 is driven in the reverse direction to move toward the inside of the threaded tube 202, thereby driving the square rod 204 to slide, and the square rod 204 drives the slider 205 to slide, thereby driving the locking column 206 to slide, so that the locking column 206 is separated from the rotary blade 102. At this time, any rotary blade 102 can be easily removed and replaced. When the replacement is completed, it is only necessary to rotate the inner six rings 201 in the opposite direction to make the threaded column 203 slide in the opposite direction through the threaded connection of the threaded tube 202, thereby driving the square rod 204 to slide, thereby driving the locking column 206 to slide into the interior of the rotary blade 102 through the square rod 204, and locking the rotary blade 102. Through the cooperation of the above parts, the rotary blade 102 can be replaced quickly and conveniently.

[0027] Please refer to Figure 2 , Figure 5 , Figure 6 , the tool assembly 1 further includes a slide groove 104;

[0028] There are multiple slide grooves 104, which are arranged in a circle on one side of the outer wall of the cross groove 103. The inner wall width of the slide groove 104 is the same as the outer wall thickness of the slider 205, and the inner wall length of the slide groove 104 is equal to the outer wall length of the slider 205 and the outer wall length of the lock column 206.

[0029] In this embodiment: by providing the slide groove 104, a basis is provided for the locking column 206 to slide out of the rotary blade 102, so that the locking and unlocking of the rotary blade 102 are achieved by controlling the connection between the locking column 206 and the rotary blade 102.

[0030] Please refer to Figure 5 , Figure 6 , the tool assembly 1 further includes a square groove 105;

[0031] The square groove 105 is arranged inside the knife shaft 101 and completely penetrates the multiple slide grooves 104. The cross-sectional area of ​​the square groove 105 is the same as the cross-sectional area of ​​the square rod 204, which is used to provide a basis for the sliding connection between the square rod 204 and the knife shaft 101.

[0032] In this embodiment: by setting the square groove 105, a basis is provided for the sliding of the square rod 204, and at the same time, the rotation of the square rod 204 is limited by the inner wall of the square groove 105, so that the threaded column 203 does not rotate, thereby realizing the threaded connection between the threaded column 203 and the threaded tube 202, and converting the rotation of the threaded tube 202 into the sliding of the threaded column 203.

[0033] Please refer to Figure 6, the tool assembly 1 further includes a rotation groove 106;

[0036] Please refer to Figure 2 The outer wall of the rotary tiller 102 is provided with two symmetrically arranged arc grooves, and the inner wall of the cross groove 103 is provided with an arc protrusion matching the arc groove, so that when the rotary tiller 102 slides into the inner wall of the cross groove 103, a clamping function is formed on the rotary tiller 102. A sliding hole penetrating the rotary tiller 102 is provided on one side of the outer wall of the rotary tiller 102, and the diameter of the inner wall of the sliding hole is the same as the diameter of the outer wall of the locking column 206.

[0037] In this embodiment: it should be supplemented that the height of the arc groove and the arc protrusion is relatively low, so that the inner wall of the cross groove 103 of the rotary tiller blade 102 fits in a state of interference fit;

[0038] By means of the arc groove provided on the outer wall of the rotary blade 102 and the arc protrusion on the inner wall of the cross groove 103, the rotary blade 102 can be locked through the cooperation of the arc groove and the arc protrusion, so that when the locking assembly 2 is in the unlocked state, the rotary blade 102 will not fall off easily and affect the operation of re-locking the tool assembly 1.
