A socket 37 is provided at the fixed frame 31 corresponding to the trapezoidal block 36. The size of the socket 37 is adapted to the size of the trapezoidal block 36. When it is necessary to install the protective plate 33, the staff moves the mounting plate 32 and inserts the mounting plate 32 into the fixed frame 31. When the inclined surface of the trapezoidal block 36 of the mounting plate 32 is against the edge of the fixed frame 31, the fixed frame 31 squeezes the inclined surface of the trapezoidal block 36, and the trapezoidal block 36 moves toward the inner direction of the groove 34. The first spring 35 contracts. When the trapezoidal block 36 moves to the position of the socket 37, under the action of the restoring elastic force of the first spring 35, the trapezoidal block 36 is inserted into the socket 37 of the fixed frame 31, thereby achieving the effect of fixing the mounting plate 32 and the protective plate 33. The protective plate 33 set by the protective device 3 achieves the effect of protecting the tool magazine body 1, preventing external weeds from entering the interior of the tool magazine body 1, thereby affecting the service life of the tool magazine body 1.
[0029] Reference Figure 1-5 As shown, the surface of the protective plate 33 is fixedly connected with reinforcing ribs 39, and several reinforcing ribs 39 are distributed linearly. The overall strength of the protective plate 33 is increased by providing the reinforcing ribs 39, thereby improving the practicality of the protective plate 33. Two positioning rods 310 are fixedly connected inside the fixed frame 31, and a positioning hole 311 is provided at the mounting plate 32 corresponding to the positioning rod 310, and the size of the positioning rod 310 is adapted to the size of the positioning hole 311. By providing the positioning rod 310 to be inserted into the positioning hole 311 of the mounting plate 32, the effect of fixing the mounting plate 32 is achieved, and the mounting plate 32 is prevented from shaking in the fixed frame 31. The inner wall of the groove 34 is fixedly connected with a telescopic rod 38, and one end of the telescopic rod 38 is fixedly connected to the trapezoidal block 36. By providing the telescopic rod 38, the effect of limiting the moving direction of the trapezoidal block 36 is achieved, thereby improving the stability of the movement of the trapezoidal block 36.

At this time, the rotary tiller and the tool magazine body 1 are fixed with the bolt 2, and then the U-shaped frame 43 is loosened. Under the action of the resetting elastic force of the second spring 42, the two arms of the U-shaped frame 43 clamp the nut of the bolt 2, thereby achieving the effect of fixing the bolt 2. The auxiliary device 4 achieves the effect of fixing the bolt 2, and prevents the bolt 2 from loosening after long-term use, thereby affecting the fixation of the rotary tiller and the tool magazine body 1.

At this time, the rotary tiller blade and the tool magazine body 1 are fixed with the bolt 2, and then the U-shaped frame 43 is loosened. Under the action of the restoring elastic force of the second spring 42, the two arms of the U-shaped frame 43 clamp the nut of the bolt 2, thereby achieving the effect of fixing the bolt 2. The auxiliary device 4 achieves the effect of fixing the bolt 2, thereby preventing the bolt 2 from loosening after long-term use, thereby affecting the fixation of the rotary tiller blade and the tool magazine body 1.
