One end of the protection sleeve 33 is provided with a fixing hole 331, a threaded sleeve 332 is fixed in the fixing hole 331, and the threaded shaft 314 is in threaded connection with the threaded sleeve 332.

The first embodiment is as follows:

when the tool holder 3 is mounted, one end of the connecting plate 2 is first inserted between the clamping plates 322 of the one cover plate 32 and the through hole 321. The end is then inserted into the attachment slot 311 until the second pin bore 312 is aligned with the first pin bore 24. In this process, the fixing groove 326 should be prevented from covering one end of the fixing block 31 and exposing the second pin shaft hole 312, as shown in fig. 3.

The pin shaft 313 is inserted into the second pin shaft hole 312, so that the pin shaft 313 penetrates through the second pin shaft hole 312 and the first pin shaft hole 24, at this time, the pin shaft 313 can limit the relative movement between the second pin shaft hole 312 and the first pin shaft hole 24, namely, the connecting plate 2 is prevented from being separated from the connecting groove 311, one end of the connecting plate 2 is sleeved by the connecting groove 311, the rotation around the pin shaft 313 between the second pin shaft hole 312 and the first pin shaft hole 24 is limited, and the effect of fixed connection between the connecting plate 2 and the fixed block 31 is achieved.

After the pin 313 is completely inserted into the second pin hole 312, the fixing groove 326 is engaged with one end of the fixing block 31, as shown in fig. 4, at this time, the fixing groove 326 blocks the second pin hole 312, so as to prevent the pin 313 from coming out of the second pin hole 312. At this time, the connecting hole 23 is aligned with the clamping plate hole 323, one end of the bolt 324 penetrates through the connecting hole 23 and the clamping plate hole 323 and is in threaded connection with the nut 325, the bolt 324 and the nut 325 are continuously rotated until the connecting plate 2 and the clamping plate 322 are tightly clamped, the cover plate 32 is fixed, on one hand, the state that the second pin shaft hole 312 is blocked is maintained, on the other hand, the fixing between the connecting plate 2 and the fixing block 31 is strengthened by matching with the clamping of the fixing groove 326 to the fixing block 31.

After the cover plate 32 is fixed, the threaded shaft 314 extends into the threaded sleeve 332, and the protective sleeve 33 is rotated, so that the protective sleeve 33 drives the threaded sleeve 332 to rotate together, so that the threaded shaft 314 and the threaded sleeve 332 are connected through threads, and the threaded shaft 314 continuously extends into the threaded sleeve 332 until the threaded sleeve 332 completely covers the threaded shaft 314, as shown in fig. 1. The protective sheath 33 is used to protect the threaded shaft 314 and the threaded sleeve 332 and is convenient for the user to hold.

Example two:

when cutting branches, the two knife handles 3 are broken off, namely, the distance between the knife handles 3 is increased, the knife head 1 is limited to slide on the hinge shaft 13 through the transmission of the connecting plate 2 and the stop block 14, the knife head 1 is driven to rotate around the hinge shaft 13, and the distance between the knife edges 11 is increased.

The two knife edges 11 are used for clamping branches to be cut off, at the moment, because one of the knife heads 1 is concave and the other knife edge is convex, the branches can be clamped and fixed by the two knife edges 11, and the branches can be cut off conveniently.

After the branch is clamped by the knife edge 11, a user pushes the two knife handles 3 towards the middle, the two knife handles are driven by the connecting plate 2 to drive the distance between the knife edges 11 to be shortened, the clamping force of the branch is increased, the clamping force is converted into shearing force through the knife edges 11, the branch is cut off, and pruning is completed.

In the twinkling of an eye of accomplishing pruning, because the user is to the great power that handle of a knife 3 applyed, let handle of a knife 3 accelerate fast to be close to fast, limit the distance between the handle of a knife 3 through buffer block 22, and through self elastic buffering when colliding with each other, let on the one hand can not collide with each other fast and damage between the handle of a knife 3, on the other hand can not let handle of a knife 3 striking user's hand, reaches protection handle of a knife 3 and user's effect.

Because the distance from the tail end of the knife handle 3 to the hinged shaft 13 is greater than the distance from the knife edge 11 to the hinged shaft 13, the hinged shaft 13 forms a lever between the knife head 1, the connecting plate and the knife handle 3, and the lever principle reduces the resistance of a user when the user prunes, so that the user can prune the knife easily.

Example three:

when the tree is hard and the user is hard to cut off the tree, the user rotates the protective sheath 33 in the reverse direction, so that the protective sheath 33 drives the threaded sleeve 332 to rotate in the reverse direction, the threaded shaft 314 extends out of the threaded sleeve 332, that is, the distance from the protective sheath 33 to the hinge shaft 13 is increased, and after the threaded shaft is rotated to a proper distance, as shown in fig. 4, the threaded shaft 314 is not pulled out of the threaded sleeve 332. The user grips the protective sheath 33 terminally to promote to be close to between the protective sheath 33, because the extension of handle of a knife 3, according to lever principle, the resistance that edge of a knife 11 transmitted to the protective sheath 33 end reduces, and it is lighter that the user prunes, is convenient for cut harder branch.

In the above shearing process, since the user holds the protective cover 33 with the hand and restricts the rotation of the threaded sleeve 332, and the threaded shaft 314 cannot rotate due to the restriction of the hinge shaft 13, the threaded shaft 314 and the threaded sleeve 332 cannot rotate relatively, so that the threaded sleeve 332 cannot move in the axial direction of the threaded shaft 314 in the shearing process, and the fixing effect is achieved.

And to softer branch, do not need great power, the user can rotate protective sheath 33, lets handle of a knife 3 shorten, needs the distance that promotes protective sheath 33 when reducing the user and build, lets the user can prune fast, increases pruning efficiency.

In conclusion, the longer the handle 3, the user can conveniently trim the harder branches, and the shorter the handle 3, the softer branches can be adapted, so that the user can conveniently and quickly trim the branches; meanwhile, by shortening the knife handle 3, the tree pruning machine can be conveniently carried by a user after pruning, and the effects of adapting to branches with different hardness and being convenient to carry are achieved.
