[0014] Compared with the prior art, the above technical solutions of the present utility model have the following beneficial technical effects:

[0015] 1. By providing a telescopic component, the combined use of the movable pulley and the first steel rope reduces the resistance of the user during pruning operations. Through the connection of the first fixing sleeve, the second fixing sleeve, and the third fixing sleeve, and the stable winding of the steel rope around the pulleys and in the card slots, the reliability and stability of the telescopic component during operation are ensured. By providing a handle, the user can control the operation of the scissor component by simply operating the handle. The operation process is simple and intuitive, allowing the user to easily get started.

[0016] 2. By providing a scissor component, a set of bolts tightly connects the first mounting shell and the second mounting shell. The first mounting outer shell and the second mounting outer shell provide stable support for components such as the first rotating shaft, the second rotating shaft, and the rollers in the scissor component, ensuring the stability and reliability of the gear scissor blades and the second scissor blade during the shearing process. By the telescopic component pulling the first connecting piece, thereby pulling the third steel rope, the first rotating shaft rotates, realizing the closing of the gear scissor blades and the second scissor blade. The meshing design of the first gear and the gear scissor blades, and the bolt movable connection between the second scissor blade and the gear scissor blades achieve the shearing function of the scissor component, enabling the transmission of greater power during pruning operations, improving the pruning efficiency. At the same time, by providing a torsion spring inside the second turntable of the scissor component, after the user releases the handle after completing the shearing, the torsion spring can automatically release energy to reset the scissor component, improving the work efficiency while also reducing the operation burden on the user.

[0017] 3. By providing a scissor component, the fourth steel rope winds around the fourth fixing block, the fifth fixing block, and the fourth movable pulley, realizing the control of the opening and closing of the third scissor blade. When the user holds the handle and pulls it along the long rod outer shell towards the tail, the telescopic component drives the second connecting piece, pulling the fourth steel rope and driving the fourth movable pulley to rotate, thereby pulling the pull rod and making the third scissor blade and the fourth scissor blade move relative to each other to achieve shearing. This design makes the opening and closing process of the scissors smoother and more stable. Since the third scissor blade is connected to the mounting sleeve through a spring, when the shearing is completed and the user releases the handle, the spring can automatically reset the third scissor blade to its initial position, improving the pruning efficiency and reducing the operation burden on the user.

[0018] 4. By providing a handle and the second steel rope, one end of the second steel rope is set on the handle, and the other end is set at the tail of the first fixing sleeve, which can limit the handle when the scissor component resets, preventing the handle from rising excessively when the torsion spring or the spring rebounds.

[0039] The scissor assembly 5 includes a second mounting housing 52 arranged at the top of the second long rod housing 32. On one side of the second mounting housing 52, a first mounting housing 51 is provided. The second mounting housing 52 and the first mounting housing 51 are connected by a set of bolts. The first mounting housing 51 and the second mounting housing 52 together form the frame of the scissor assembly 5, providing the installation space for the scissor blades and the necessary structural support. They are tightly connected together by a set of bolts to ensure the stability of the scissor assembly 5. Between the first mounting housing 51 and the second mounting housing 52, a first rotating shaft 57 is provided. On the first rotating shaft 57, a first hexagonal shaft sleeve 515 and a second hexagonal shaft sleeve 516 are provided. On the first hexagonal shaft sleeve 515, a first turntable 54 is provided. The first turntable 54 is located inside the first mounting housing 51. The first rotating shaft 57 passes through the first mounting housing 51 and the second mounting housing 52, supporting the first turntable 54 and the second turntable 56.

The fourth steel rope 525 is provided on the fourth fixed block 523. The fourth fixed block 523 fixes the starting point of the fourth steel rope 525. It successively winds around the fifth fixed block 524 and the fourth movable pulley 527. The tail of the fourth steel rope 525 is fixed inside the first fixed cylinder 520. By setting the fourth movable pulley 527, the winding direction of the fourth steel rope 525 is changed, reducing friction and wear, and realizing the transmission of force and the change of direction.

[0046] When in use, the user holds the handle 4 and moves along the first long rod housing 1 towards the tail direction. During the movement of the handle 4, the first steel rope 34 is pulled. By means of the first movable pulley 313, the second movable pulley 39 and the third movable pulley 310, the winding path of the first steel rope 34 is changed, realizing the transmission of force and the change of direction, reducing the operating resistance of the user, so that the first moving block 37 moves along the inner wall of the second long rod housing 32 towards the tail.

[0047] The first moving block 37 drives the second connecting piece 522 to move along the inner wall of the second long rod housing 32 towards the tail, thereby pulling the fourth steel rope 525. The fourth steel rope 525 pulls the second moving block 526 to move along the inner wall of the second long rod housing 32 towards the tail, thereby driving the pull rod 528 to move, making the third scissor blade 529 and the fourth scissor blade 530 close to realize pruning. At this time, the spring 531 is stretched due to the closing of the third scissor blade 529. After pruning is completed, the user releases the handle 4, and the spring 531 rebounds to reset the third scissor blade 529.
