[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figure 1-6 As shown, this utility model provides a tool structure for an orchard pruning machine that facilitates blade replacement, including a pruning machine body 1 and a tool body 2. The tool body 2 has two blades that cooperate with each other. Two symmetrically distributed drive rods 11 are installed on one side of the drive end of the pruning machine body 1. The movement of the two drive rods 11 is fixedly installed with connecting blocks 12. One end of the two tool bodies 2 is in contact with the connecting blocks 12. Two symmetrically distributed second fixing holes 21 are opened on one side of each of the two tool bodies 2. Two symmetrically distributed first fixing holes 131 are opened in the middle of both sides of the two connecting blocks 12. Bolts 13 are slidably inserted through the middle of the multiple first fixing holes 131. Bolts 13 are slidably inserted through the middle of the multiple second fixing holes 21. Nuts 14 that cooperate with each other are threaded on one end of the multiple bolts 13. Two symmetrically distributed protective covers 3 are provided on the drive end of the pruning machine body 1. The two protective covers 3 are in close contact with each other. Two symmetrically distributed mounting holes 34 are opened on both sides of the two protective covers 3.

[0019] A fixing rod 35 is slidably engaged in the middle of each of the multiple mounting holes 34. A spring 37 is fixedly installed at the lower part of each of the multiple fixing rods 35. A moving block 39 is fixedly installed at the upper part of each of the multiple springs 37. A number of support blocks 391 arranged in a ring array are movably installed on the outer side of each of the multiple moving blocks 39. The top of each of the multiple support blocks 391 is in contact with the outer side of the protective cover 3. A rotating block 36 is threadedly installed on the upper part of each of the multiple fixing rods 35. The bottom of each of the multiple rotating blocks 36 is in contact with the outer surface of the protective cover 3.

[0020] Two symmetrically distributed sliders 22 are fixedly installed at one end of each of the two tool bodies 2. Two symmetrically distributed grooves 221 are opened on the inner wall of each of the two connecting blocks 12. The four sliders 22 are slidably locked inside the grooves 221. By setting the grooves 221, the tool body 2 and the connecting block 12 can be limited and fixed, so that they can be easily fixed by bolts 13.

[0021] Four symmetrically distributed limiting rods 31 are fixedly installed on the drive end of the trimmer body 1. Two symmetrically distributed limiting blocks 311 are fixedly installed on one side of each of the two protective covers 3. The middle of each of the four limiting blocks 311 is slidably locked onto the outer surface of the limiting rods 31. By setting the limiting rods 31 and the limiting blocks 311, the protective covers 3 are limited, thereby connecting the protective covers 3 and the trimmer body 1.

[0022] A shielding brush 32 is fixedly installed on one side of each of the two protective covers 3. By setting the shielding brush 32, the front of the protective cover 3 is protected without affecting the normal operation of the tool body 2 in reciprocating movement, so as to prevent debris from entering the interior of the protective cover 3.

[0023] Four evenly distributed positioning blocks 33 are fixedly installed at the bottom of one of the protective covers 3. The lower parts of the four positioning blocks 33 are slidably locked onto the upper part of the other protective cover 3. By setting the positioning blocks 33, the two protective covers 3 can be limited and positioned.

[0024] The lower part of each of the four fixed rods 35 is fixedly installed with a telescopic rod 38, and the bottom end of each of the four moving blocks 39 is fixedly installed with the top end of the telescopic rod 38. By setting the telescopic rod 38, when the rotating block 36 is rotated so that its support block 391 is close to the protective cover 3 and pressed, the telescopic rod 38 limits the moving block 39 to move upward to the limit value without damaging the spring 37, and at the same time makes the limit more stable.

[0025] The lower part of each of the four fixing rods 35 is provided with a groove 392, and multiple support blocks 391 are slidably locked in the middle of the groove 392. By setting the groove 392, when it is necessary to retract, the rotating block 36 is loosened to move it away from the protective cover 3, so that the support block 391 can be pressed into the inside of the groove 392, and the fixing rod 35 can be taken out from the mounting hole 34, that is, the restriction on the protective cover 3 is released.

[0026] Working principle: In actual use, when installing the blades on the trimmer body 1, the blade body 2 moves and comes into contact with the connecting block 12, so that the first fixing hole 131 and the second fixing hole 21 are aligned with each other. After the bolt 13 passes through the first fixing hole 131 and the second fixing hole 21, a nut 14 is installed on one end of the bolt 13 so that the nut 14 comes into contact with one side of the connecting block 12, thereby completing the connection between the blade body 2 and the drive rod 11.

[0027] By sliding the limiting blocks 311 on both sides of the two protective covers 3 onto the outer surface of the limiting rod 31, the positioning block 33 on one side of the protective cover 3 comes into contact with one side of the other protective cover 3. By sliding the fixing rod 35 through the mounting hole 34, the pushing moving block 39 moves upward under the force of the spring 37. Under the limitation of the groove 392, the upper part of the support block 391 expands outward. By rotating the rotating block 36, it moves downward, thereby reducing the distance between the rotating block 36 and the support block 391. The top of the support block 391 comes into contact with the bottom of the protective cover 3, and the bottom of the rotating block 36 comes into contact with the top of the protective cover 3. Thus, the upper and lower protective covers 3 are limited and fixed. That is, the installation of the protective covers 3 protects the connection between the blade body 2 and the drive rod 11, as well as the connection entrance between the drive rod 11 and the trimmer body 1.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
