[0021] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0022] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0023] like Figures 1-4 As shown, the telescopic high-branch saw for pruning pear branches of this application includes a saw blade 1 for cutting pear branches; a telescopic rod 2 for adjusting the working height; a connecting seat 3 for connecting the saw blade 1 and the telescopic rod 2; a guide ring 4 disposed between multiple telescopic joints of the telescopic rod 2 for guiding the relative movement of the telescopic joints; and a handle 5 for the operator to grip. The various components cooperate with each other through appropriate structural design and assembly methods to achieve synergistic effects on the overall function.

[0024] The saw blade 1 is installed at one end of the telescopic rod 2, and is usually fixed to the top of the telescopic rod 2 via a connecting seat 3. The connecting seat 3 adopts a rigid structure design, which can stably transmit the saw blade 1 to the end of the telescopic rod 2, while ensuring that the saw blade 1 remains stable under rotation or stress. This connection method may include threaded connection, plug connection, or snap-fit ​​fixing, depending on the actual use requirements.

[0025] The telescopic pole 2 is a multi-section structure, with adjustable length along the axial direction, allowing users to adapt to branch pruning needs at different heights. Each section of the telescopic pole 2 can slide relative to each other and be locked in different positions. Its overall structure is generally made of high-strength metal materials to ensure sufficient structural strength and stability under external forces.

[0026] Guide rings 4 are installed at the contact points between adjacent telescopic sections of the telescopic rod 2. They are used to guide the relative movement of each section during telescopic movement, preventing structural loosening or operational imbalance caused by offset or misalignment. The inner side of the guide ring 4 is usually provided with grooves or holes so that it can be fitted onto the telescopic section in the extended or retracted state, thus playing a stabilizing role.

[0027] Each guide ring 4 has multiple guide grooves 41 between each expansion joint. These guide grooves 41 are distributed at different positions along the axial direction of the expansion rod 2, so that when the expansion joint moves, it can move linearly along the guide grooves 41. This structural design can effectively constrain the radial displacement of the expansion joint during the expansion and contraction process, thereby ensuring that the overall structure maintains stable operation during the expansion and contraction process.

[0028] The guide ring 4 also has annular grooves 42 at the joints of each expansion joint to further stabilize the positional relationship between the expansion joints and prevent unnecessary displacement between them due to external vibration or improper operation. The design of the annular grooves 42 is usually matched with the surface shape of the expansion joint, so that it can fit tightly after insertion, enhancing the overall rigidity of the entire expansion rod 2.

[0029] The guide ring 4 is also provided with a limiting protrusion 43 on the outer side of the telescopic rod 2. This structure is used to limit the lateral movement that may occur when the telescopic joint is fully extended. The limiting protrusion 43 is usually located on the outer surface of the telescopic rod 2 and moves synchronously with the extension of the telescopic joint to prevent it from shaking or deviating from the expected path during use.

[0030] The telescopic high-branch saw for pruning pear branches described in this application effectively solves the problem of radial swaying that may occur when multiple sections are extended by setting a guide ring 4 and its guide groove 41, annular groove 42 and limiting protrusion 43. The guide groove 41 guides the telescopic joint to move smoothly along the axial direction, the annular groove 42 strengthens the interlocking relationship between sections, and the limiting protrusion 43 further locks the position of the telescopic joint at extreme positions to prevent radial displacement due to uneven force or operational errors, thereby improving the stability of the product and the safety of use.

[0031] like Figure 1 and Figure 2As shown, in one embodiment, the guide ring 4 of the telescopic high-branch saw for pruning pear branches of this application is located between the middle telescopic joint and the upper telescopic joint of the telescopic rod 2, and its installation position is located at the junction of two adjacent telescopic joints. The guide ring 4 is fixed to the inner wall of the telescopic rod 2 by welding to ensure the stability between the guide ring 4 and the telescopic rod 2. This structure can prevent the telescopic joint from shifting or getting stuck during sliding, thereby improving the overall reliability and smoothness of operation. The fixed position and connection method of the guide ring 4 on the inner wall of the telescopic rod 2 play a key role in maintaining the axial movement direction of the telescopic rod 2.

[0032] Specifically, the guide ring 4 is fixed to the inner wall of the telescopic rod 2 by welding. Specifically, a corresponding mounting groove is opened at the junction of the middle telescopic joint and the upper telescopic joint of the telescopic rod 2, and the guide ring 4 is embedded and then spot welded or fully welded to form an unremovable fixed connection between the guide ring 4 and the telescopic rod 2, ensuring that the guide ring 4 exists stably inside the telescopic rod 2 and can effectively guide the relative movement of adjacent telescopic joints.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, the guide ring 4 of the telescopic high-branch saw for pruning pear branches of this application is located between the bottom telescopic joint and the middle telescopic joint of the telescopic rod 2. This position ensures that the relative movement between the telescopic joints can be effectively guided when the telescopic rod 2 is extended or retracted. The guide ring 4 is installed on the outside of the telescopic rod 2 and is fixed to the telescopic rod 2 by a threaded connection, thereby preventing the components from loosening due to vibration or operating force during use. This structural design ensures that the telescopic rod 2 maintains stability and guidance during extension and retraction, improving the overall reliability of the equipment.

[0034] For example, the guide ring 4 is screwed and fixed to the connection between the bottom telescopic joint and the middle telescopic joint of the telescopic rod 2 via external threads, so that the guide ring 4 and the telescopic rod 2 form a stable connection. At the same time, multiple guide grooves 41 are provided inside the guide ring 4, so that it forms a guiding fit with each telescopic joint, ensuring the stable movement of the telescopic joint in the axial direction without deviation or jamming.

[0035] like Figure 3As shown, in one embodiment, the guide ring 4 of the telescopic high-branch saw for pruning pear branches of this application includes two symmetrically arranged semi-ring structures 8, which are connected by locking bolts 9. The guide ring 4 is installed on the outer surface of adjacent telescopic joints of the telescopic rod 2, serving to guide the relative movement of the telescopic joints. A guide groove 41 is provided between the guide ring 4 and the telescopic joint, with each guide groove 41 distributed along the axial direction of the telescopic rod 2, forming a guiding fit with adjacent telescopic joints. Simultaneously, the guide ring 4 has an annular groove 42 at the connection between each telescopic joint to maintain the relative position stability of adjacent telescopic joints. A limiting protrusion 43 is also provided on the outer side of the guide ring 4 to prevent radial displacement of the telescopic joints in the extended state.

[0036] For example, two semi-ring structures 8 are fitted around the outer side of adjacent expansion joints, and locking bolts 9 are passed through the through holes on both semi-rings and tightened to the appropriate position, so that the entire guide ring 4 is firmly fixed to the outer side of the expansion rod 2. The contact surface between the guide groove 41 and the expansion joint remains in close contact to ensure the stability of the expansion process. The limiting protrusion 43 forms a partial fitting structure with the outer wall of the expansion joint, improving the overall structure's resistance to deformation.

[0037] like Figure 1 and Figure 2 As shown, in one embodiment, the guide groove 41 of the telescopic high-branch saw for pruning pear branches of this application is a U-shaped groove structure 10, which is set on the outer wall of each telescopic joint of the telescopic rod 2 and is adapted to the inner edge of the guide ring 4. This structure can ensure that the telescopic joint maintains a stable guiding effect during the axial sliding process and prevents unstable operation caused by shaking. The guide groove 41 is distributed at different positions along the axial direction of the telescopic rod 2, thereby cooperating with multiple telescopic joints for multi-level adjustment to achieve highly flexible operation requirements. The guide ring 4 is set between multiple telescopic joints, so that each telescopic joint can smoothly extend and retract within a limited range.

[0038] For example, U-shaped groove structures 10 are machined on the outer wall of each telescopic joint of the telescopic rod 2. Their shape matches the inner edge of the guide ring 4. When the telescopic joint extends or retracts, the guide ring 4 slides along the U-shaped groove, thereby maintaining the stability of the overall structure. At the same time, the arrangement of the guide groove 41 is determined according to the connection part of each telescopic joint, so that the guide ring 4 is always in contact with the corresponding telescopic joint and plays its role during the movement.

[0039] like Figure 4As shown, in one embodiment, the annular groove 42 of the telescopic high-branch saw for pruning pear branches of this application is provided with multiple positioning pin holes 11, and is connected to adjacent telescopic sections through positioning pins 12 to achieve a stable fixation. This structure is used to ensure that the relative position between each telescopic section can remain stable after adjusting the length of the telescopic rod 2, avoiding slippage or misalignment due to external forces. The annular groove 42 is provided at the connection parts of each telescopic section of the guide ring 4, and its design can fit tightly with the positioning pins 12, thereby enhancing the rigidity and stability of the overall structure.

[0040] Specifically, the annular groove 42 has multiple evenly distributed positioning pin holes 11 at the connection of each expansion joint. The positioning pins 12 pass through the pin holes and embed into the inner wall of the adjacent expansion joint, forming a detachable fixed connection between the two. This method improves the stability of the expansion rod 2 during use through mechanical locking, while allowing the operator to disassemble or adjust the connection status of each part according to actual needs.

[0041] like Figure 4 As shown, in one embodiment, the limiting protrusion 43 of the telescopic high-branch saw for pruning pear branches of this application is a conical structure 13, located on the outer edge of the guide ring 4, and in contact with the stepped surface inside the telescopic rod 2. This structure is designed to provide radial positioning during the sliding of multiple telescopic sections of the telescopic rod 2, thereby enhancing the stability of the telescopic process. The limiting protrusion 43 is located near the outer side of the guide ring 4, which can effectively prevent the telescopic rod 2 from shifting due to operating force or external impact during operation. As a key component connecting different telescopic sections, the structural arrangement of the guide ring 4 directly affects the overall stability and adjustment accuracy.

[0042] For example, the outer edge of the guide ring 4 is machined into a tapered structure 13. This structure must precisely match the corresponding step surface on the inner wall of the telescopic rod 2 to ensure a tight fit and reliable positioning. The limiting protrusion 43 achieves its positioning function through compression contact with the step surface of the telescopic rod 2, eliminating the need for additional fasteners, simplifying the structural design, and improving assembly efficiency. This connection method ensures that the limiting protrusion 43 can always slide along the set path during telescopic movement, while limiting radial displacement and improving overall safety.

[0043] like Figure 1 and Figure 2 As shown, in one embodiment, an elastic buffer sleeve 14 is further provided between the guide ring 4 and the telescopic rod 2 of the telescopic high-branch saw for pruning pear branches of this application, to reduce friction and radial impact during extension and retraction. The elastic buffer sleeve 14 is located in the contact area between the guide ring 4 and the telescopic rod 2, mainly serving to dampen shocks and buffer, thereby improving the smoothness of the extension and retraction operation and extending its service life. This structural design effectively avoids component wear and potential displacement risks caused by repeated extension and retraction.

[0044] Specifically, the elastic buffer sleeve 14 is disposed between the guide ring 4 and the telescopic rod 2. One end of the sleeve is attached to the outer surface of the telescopic rod 2, and the other end is embedded in the inner side of the guide ring 4. It is fixed by bonding or interference fit to ensure that it maintains a stable position during the telescopic process.

[0045] like Figure 2 As shown, in one embodiment, the guide groove 41 of the telescopic high-branch saw for pruning pear branches of this application is disposed between multiple telescopic joints and distributed along the axial direction of the telescopic rod 2, with its groove depth gradually decreasing from bottom to top. This design can match the sliding requirements of different telescopic joints during movement, thereby improving the stability of the structure. The guide groove 41 forms a tight fit with adjacent telescopic joints, ensuring smooth telescopic process while avoiding positional displacement caused by uneven friction. The depth variation of the guide groove 41 can also reduce vibration or jamming caused by structural deformation during telescopic process.

[0046] Specifically, the guide groove 41 is machined onto the inner surface of the guide ring 4, and its cross-sectional shape is wedge-shaped or arc-shaped. The guide groove 41 is positioned corresponding to each expansion joint, and the bottom of the groove gradually becomes flatter. This structure is achieved by machining the inside of the guide ring 4 in segments according to the stroke range of each expansion joint, making the lower guide groove 41 deeper to facilitate guidance during the early expansion stage, while the upper groove gradually becomes shallower to adapt to the stable state after the expansion joint is fully deployed.

[0047] In one embodiment, the annular groove 42 of the telescopic high-branch saw for pruning pear branches of this application is provided at the connection of each telescopic joint of the guide ring 4. Its function is to fix the relative position between adjacent telescopic joints and prevent loosening or misalignment after the telescopic rod 2 is extended. The diameter of the annular groove 42 is designed to be greater than or equal to the outer diameter of the adjacent telescopic joint to ensure a tight fit when the telescopic rod 2 is in the working state. This structure can improve the stability and operational accuracy of the overall device without affecting the telescopic action. At the same time, the design of the annular groove 42 also helps to extend the service life of the telescopic rod 2 and reduce the risk of component damage due to frequent use.

[0048] Specifically, the annular groove 42 is integrally formed with the guide ring 4 by casting or stamping, and is arranged between adjacent expansion joints. Its internal contour matches the external shape of the expansion joint, thereby achieving a stable fitting connection. When the expansion rod 2 is in the extended state, the outer wall of the expansion joint directly abuts against the inner wall of the annular groove 42, maintaining a fixed distance between the sections and forming a reliable positioning. In addition, the annular groove 42 also facilitates the alignment of the expansion joints during installation, ensuring smooth and jam-free operation of the expansion rod 2.

[0049] like Figure 4As shown, in one embodiment, the guide ring 4 of the telescopic high-branch saw for pruning pear branches of this application is entirely wrapped between two adjacent telescopic sections of the telescopic rod 2 and connected to the telescopic rod 2 via a snap-fit ​​structure 18. The guide ring 4 ensures that each telescopic section can slide stably along the axial direction during telescopic movement, preventing jamming or displacement. The snap-fit ​​structure 18 is used to fix the position of the guide ring 4, ensuring that the guide ring 4 and the telescopic rod 2 move synchronously, thereby guaranteeing the smooth operation and stability of the entire telescopic mechanism. This structural design improves the efficiency and operational safety of the high-branch saw at different working heights.

[0050] Specifically, the guide ring 4 is positioned among the multiple telescopic sections of the telescopic rod 2 via a snap-fit ​​structure 18. The snap-fit ​​structure 18 is disposed on the outer wall of the guide ring 4 and embedded in the corresponding groove of the telescopic rod 2, thereby achieving a tight connection between the guide ring 4 and the telescopic rod 2. At the same time, the guide groove 41 inside the guide ring 4 cooperates with the adjacent telescopic sections, enabling each section to move in a predetermined direction during the stretching or contraction process, thereby enhancing the stability and coordination of the overall structure.

[0051] In actual operation, when this device is used, the operator holds the handle 5 and adjusts the telescopic rod 2 to a suitable height, so that the saw blade 1 is aligned with the pear branch to be pruned. The length of the telescopic rod 2 can be adjusted to adapt to different working environments. Multiple guide grooves 41 on the guide ring 4 form a guiding fit with the telescopic joint to ensure that the telescopic rod 2 remains stable during movement. At the same time, the annular groove 42 is used to fix the position of the telescopic joint to prevent displacement during operation. The limiting protrusion 43 prevents the telescopic joint from radially shifting when it is extended. After confirming the position, the operator holds the handle 5 and pushes the saw blade 1 to cut the branch, thereby completing the pruning of the pear branch.

[0052] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.
