[0034] Reference Figures 1 to 4 A high-altitude shears comprises a grip assembly 100, a shearing mechanism, a traction rope assembly 300 and a storage assembly 400. The shearing mechanism is connected to the upper end of the grip assembly 100 and comprises a shearing blade 210 and a fixed blade 220. The traction rope assembly 300 is respectively connected to the storage assembly 400 and the shearing mechanism. The storage assembly 400 has a cavity 401, in which a winding disk 420 is rotatably arranged. The traction rope assembly 300 can be at least partially received in the cavity 401 and wound on the winding disk 420. The storage assembly 400 can drive the shearing blade 210 to rotate relative to the fixed blade 220 through the traction rope assembly 300, so as to cooperate with the fixed blade 220 for shearing or to open relative to the fixed blade 220.

[0035] It is understandable that if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when in use, the traction rope assembly 300 is connected to the storage assembly 400 and the shearing mechanism respectively. The operator can pull the traction rope assembly 300 by grasping the storage assembly 400, so as to use the traction rope assembly 300 to drive the shearing blade 210 to rotate relative to the fixed blade 220, so that the shearing blade 210 cooperates with the fixed blade 220 to shear or opens relative to the fixed blade 220, and controls the action of the shearing mechanism to achieve pruning of high tree branches. When facing pruning operations at different heights or operators at different heights, the winding disk 420 can be rotated to allow the excess traction rope assembly 300 to be stored in the cavity 401 of the storage assembly 400 and wound on the winding disk 420, so as to avoid the excess rope segments affecting the operation. The storage operation is simple and convenient, and easy to use.

[0036] In actual application, the specific structures of the grip assembly 100, the shearing mechanism, the traction rope assembly 300 and the storage assembly 400 can be set accordingly according to actual use needs, and will not be described in detail here, but will be explained in detail below.

[0037] In some embodiments, the storage assembly 400 includes a shell 410 and a first elastic member, a cavity 401 is disposed in the shell 410, the first elastic member is disposed in the cavity 401 and is respectively connected to the shell 410 and the winding drum 420, and the winding drum 420 has a rotation tendency to wind the traction rope assembly 300 into the cavity 401 under the action of the first elastic member.

[0038] It is understandable that if Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the storage assembly 400 includes a shell 410, a cavity 401 is arranged in the shell 410, and an opening 402 communicated with the cavity 401 is provided on the shell 410, so that the traction rope assembly 300 can extend into the cavity 401 and be connected with the winding disk 420, and a first elastic member (not shown in the figure) is provided between the shell 410 and the winding disk 420, and the first elastic member acts on the winding disk 420, so that the winding disk 420 has a rotation tendency to reel the traction rope assembly 300 into the cavity 401, under this tendency, the excess traction rope assembly 300 can be automatically reeled on the winding disk 420, so that the traction rope assembly 300 between the shearing mechanism and the storage assembly 400 is kept tensioned for easy use. In actual application, the first elastic member can be a torsion spring or a coil spring, etc., preferably a coil spring; in addition to setting the first elastic member to rotate the winding disk 420, a handle can also be set to be connected to the winding disk 420, and the winding disk 420 can be driven to rotate by operating the handle. The specific setting can be based on actual use needs.

[0039] Further, the storage assembly 400 is provided with a locking structure, and the locking structure can limit the rotation of the winding disk 420 relative to the housing 410. It is understandable that by setting a locking structure to limit the rotation of the winding disk 420 relative to the housing 410, the traction rope assembly 300 between the storage assembly 400 and the shearing mechanism is locked after the length adjustment. When the traction rope assembly 300 is pulled by the storage assembly 400, it is helpful to prevent the traction rope assembly 300 from pulling the winding disk 420 in the opposite direction to rotate, which is convenient for operation and use. In actual application, if the winding disk 420 is operated and rotated by a handle, the locking structure can be set on the handle, such as tightening the screw on the handle so that the handle is pressed against the housing 410, or the handle can be moved relative to the housing 410, and the two can be matched and separated by a spline structure or a face gear structure to achieve rotation restriction and release restriction, which can be changed accordingly according to actual use needs.

[0040] Furthermore, the locking structure includes a first operating member 430 and a locking recess 421. The first operating member 430 is rotatably connected to the shell body 410 and is provided with a locking portion 431 located in the cavity 401. The locking recess 421 is provided with multiple and is arranged around the outer periphery of the winding disk 420. The first operating member 430 can be rotated until the locking portion 431 is engaged with the locking recess 421 or disengaged from the locking recess 421 to limit the rotation of the winding disk 420 or release the rotation restriction of the winding disk 420.

[0041] It is understandable that if Figure 3 and Figure 4 As shown, the figure shows an embodiment of the storage component 400, wherein the locking structure includes a first operating member 430 and a locking recess 421. In this embodiment, ratchets are provided on both sides of the winding disk 420, and the locking recess 421 is a recessed structure between two adjacent ratchet teeth on the ratchet. The first operating member 430 is rotatably connected to the shell 410 and is provided with a locking portion 431 located in the accommodating cavity 401. The locking portion 431 is provided with two and corresponds to the two ratchets. The locking portion 431 serves as a pawl, and the ratchets on both sides of the winding disk 420 turn in opposite directions. When it is necessary to limit the rotation of the winding drum 420, the first operating member 430 is rotated to make the locking portion 431 engage in the locking recess 421, and the two ratchet pawls cooperate to limit the rotation in the clockwise and counterclockwise directions respectively, thereby fixing the winding drum 420; when it is necessary to release the rotation restriction of the winding drum 420, the first operating member 430 is rotated to make the locking portion 431 disengage from the locking recess 421. At this time, the winding drum 420 can rotate relative to the shell 410, and the traction rope assembly 300 is reeled into the cavity 401 or the traction rope assembly 300 is sent out from the cavity 401. Its structure is simple and easy to use.

[0042] In actual application, an elastic member such as a spring or a torsion spring can be arranged between the first operating member 430 and the shell 410. The elastic member is used to act on the first operating member 430 to keep the locking portion 431 stuck in the locking recess 421, thereby achieving a relatively stable locking effect. When unlocking, the first operating member 430 is pressed to overcome the force of the elastic member and rotate. The specific setting can be made according to actual usage needs.

[0043] Furthermore, the locking structure includes a second operating member 440, a locking member 450 and a locking recess 421. The second operating member 440 is movably connected to the shell 410 and is provided with a push portion 441. The locking member 450 is located in the accommodating cavity 401 and is rotatably connected to the shell 410. The locking recess 421 is provided with a plurality of and is ring-arranged around the outer periphery of the winding disk 420. The second operating member 440 can be moved to make the push portion 441 push the locking member 450 to rotate, so that the locking member 450 can be stuck in the locking recess 421 to limit the rotation of the winding disk 420.

[0044] It is understandable that if Figure 5and Figure 6 As shown, the figure shows another embodiment of the storage component 400, wherein the locking structure includes a second operating member 440, a locking member 450 and a locking recess 421. In this embodiment, a gear is provided on the side of the winding disk 420, and the locking recess 421 is a tooth groove structure between two adjacent teeth on the gear. The second operating member 440 is movably connected to the shell 410 and is provided with a push portion 441. The locking member 450 is located in the cavity 401 and is rotatably connected to the shell 410. When it is necessary to limit the rotation of the winding disk 420, the second operating member 440 is moved, so that the pushing portion 441 pushes the locking member 450 to rotate, and the locking member 450 rotates to be engaged with the locking recess 421 to limit the rotation of the winding disk 420 and fix the winding disk 420; when it is necessary to release the rotation restriction of the winding disk 420, the second operating member 440 is moved, so that the pushing portion 441 releases the pushing of the locking member 450, and the locking member 450 can be rotated to disengage from the locking recess 421 to achieve unlocking. Its structure is simple and easy to use.

[0045] In actual application, the rotation of the locking member 450 out of the locking recess 421 can be achieved by setting an elastic member such as a spring or a torsion spring, or usually by its own gravity, or by magnetic attraction with the push portion 441. The push portion 441 and the locking member 450 can also be connected by a connecting rod to form a slider rocker mechanism, and the slider is used to drive the rocker to rotate; preferably, when the locking member 450 is inserted into the locking recess 421, the direction of the force that the locking member 450 reacts on the second operating member 440 is perpendicular to the moving direction of the second operating member 440, so that the locking member 450 cannot push the second operating member 440 to move; in order to maintain a better locking effect, an elastic member such as a spring can be provided between the second operating member 440 and the housing 410, and the elastic member is used to act on the second operating member 440 so that the second operating member 440 can be kept in the locked position, or the second operating member 440 can be kept in the locked position through a clamping structure, and the specific setting can be made according to actual use needs.

[0046] In some embodiments, the storage assembly 400 and the handle assembly 100 are detachably connected via a snap-fit ​​structure. Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the clamping structure includes a connecting portion 411 provided on the housing 410, which is a "C"-shaped structure and can be deformed. When in use, the connecting portion 411 can be fixed to or detached from the handle assembly 100 through the "C"-shaped structure, so as to achieve quick assembly and disassembly between the storage assembly 400 and the handle assembly 100, which is convenient for use. In actual application, the clamping structure can also include a buckle slot, which can be set accordingly according to actual use needs.

[0047] In some embodiments, the storage assembly 400 is provided with a handle 412. It is understood that Figures 1 to 6 As shown, a handle 412 is provided at the lower part of the housing 410, so that the operator can move the storage assembly 400 by grasping the handle 412, thereby pulling the traction rope assembly 300, which is convenient for operation and use. In actual application, the specific structure of the handle 412 can be set accordingly according to actual use needs.

[0048] In some embodiments, the traction rope assembly 300 includes a first pull rope segment 310, a second pull rope segment 320 and a wheel seat 340, the two ends of the first pull rope segment 310 are respectively connected to the shearing mechanism and the wheel seat 340, a movable pulley is provided on the wheel seat 340, a fixed pulley 111 is provided on the grip assembly 100, the second pull rope segment 320 is wound around the fixed pulley 111 and the movable pulley, and the two ends of the second pull rope segment 320 are respectively connected to the wheel seat 340 and the storage assembly 400.

When in use, the third traction rope segment 330 is pulled by the storage assembly 400, the third traction rope segment 330 pulls the second traction rope segment 320, the second traction rope segment 320 pulls the wheel seat 340 to move, and the wheel seat 340 pulls the first traction rope segment 310, thereby realizing the control of the shearing mechanism, by setting the movable pulley and the fixed pulley 111, and using the labor-saving structure of the double pulleys, it is beneficial to save the pulling force required by the operator to pull the traction rope assembly 300, and it is convenient to use.

[0050] In actual application, the second pull rope segment 320 and the third pull rope segment 330 can be two segments of the same rope, or the first pull rope segment 310, the second pull rope segment 320 and the third pull rope segment 330 can be three segments of the same rope. In addition to the above structure, the traction rope assembly 300 can also be a simple rope structure, directly connecting the shearing mechanism and the storage assembly 400, which can be changed accordingly according to actual use needs.

[0051] In some embodiments, the shearing mechanism also includes a mounting seat 230 and a rotating disk 240, the mounting seat 230 is connected to the end of the grip assembly 100, the rotating disk 240 is rotatably connected to the mounting seat 230, the fixed blade 220 is fixedly connected to the mounting seat 230, the traction rope assembly 300 is connected to the rotating disk 240 and can pull the rotating disk 240 to rotate, the shearing blade 210 is connected to the rotating disk 240 and can be driven to rotate by the rotating disk 240, and a second elastic member 231 is arranged between the mounting seat 230 and the rotating disk 240, and the rotating disk 240 can be reset and rotated under the action of the second elastic member 231 until the shearing blade 210 is opened relative to the fixed blade 220.

[0052] It is understandable that if Figure 1 and Figure 2 As shown, the mounting seat 230 is fixedly connected to the end of the grip assembly 100, the rotating disk 240 is rotatably connected to the mounting seat 230, the fixed blade 220 is fixedly connected to the mounting seat 230, the first pull rope segment 310 is connected to the rotating disk 240 and can pull the rotating disk 240 to rotate, the shearing blade 210 is connected to the rotating disk 240 and can be driven to rotate by the rotating disk 240, when the rotating disk 240 rotates, it can drive the shearing blade 210 and the fixed blade 220 to perform shearing or opening action, the structure is compact, which is conducive to ensuring the normal cutting work; the second elastic member 231 can be a torsion spring or a coil spring, which is arranged on the mounting seat 230 and acts on the rotating disk 240, and the second elastic member 231 can be used to realize the reset rotation of the rotating disk 240, so that the shearing blade 210 and the fixed blade 220 are reset to the open position for the next shearing.

[0053] Preferably, the shearing mechanism also includes a connecting rod 250, and the shearing blade 210 is connected to the rotating disk 240 through the connecting rod 250. The middle part of the shearing blade 210 is rotatably connected to the fixed blade 220. One end of the shearing blade 210 is a blade portion, and the other end thereof is hinged to one end of the connecting rod 250. The other end of the connecting rod 250 is rotatably set at an eccentric position of the rotating disk 240, so that a four-bar linkage mechanism is formed between the shearing blade 210, the fixed blade 220, the connecting rod 250 and the rotating disk 240. When the rotating disk 240 rotates, it can drive the shearing blade 210 to rotate relative to the fixed blade 220 to form a shearing or opening action. Moreover, through the four-bar linkage structure, the shearing force between the shearing blade 210 and the fixed blade 220 or the maximum diameter of the branch that can be sheared can be increased to meet different usage requirements.

[0054] In actual application, in addition to the above structure, the shearing blade 210 can also be directly fixed on the rotating disk 240, and rotate with the rotating disk 240 to move relative to the fixed blade 220 to achieve shearing and opening actions. The specific structure of the shearing mechanism can also be changed accordingly according to actual use needs.

[0055] Furthermore, a saw blade 260 is disposed on the mounting base 230. It is understood that Figure 1 and Figure 2 As shown, when in use, the sawing operation can be performed by the saw blade 260, thereby increasing the functionality of the utility model and facilitating use.

[0056] In some embodiments, the grip assembly 100 is provided with a telescopic structure, and the grip assembly 100 can be adjusted to change its length through the telescopic structure.
