[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0036] Example 1 Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides an electric pruning shear for pruning branches. The electric pruning shear includes a main body component 1 and a closing component 2. With the cooperation of the closing component 2, the main body component 1 can seal the compartment when idle, and can also open automatically when in use. It is easy to use and has a good sealing effect on the battery compartment 13.

[0037] Main component 1 is the basic load-bearing structure of the equipment, including handle 11. Handle 11 is designed as an ergonomic cylinder and is made of non-slip rubber material to improve grip comfort and stability and reduce the risk of hand slippage during operation. One end of handle 11 is fixedly connected to drive block 12. Drive block 12 integrates motor working parts to provide power for the cutting action of scissor blade 16. This is existing technology and will not be described in detail here. The other end of handle 11 is fixedly connected to battery compartment 13. Battery compartment 13 is a rectangular hollow structure and serves as the mounting carrier for lithium battery.

[0038] The enclosure component 2 includes a double-opening plate 21 disposed on one side of the battery compartment 13. The double-opening plate 21 is disposed below the battery compartment 13 and has synchronous opening and closing characteristics. A dovetail groove 22 is provided inside the battery compartment 13. A dustproof plate 23 is rotatably connected to the end of the dovetail groove 22. When the dustproof plate 23 rotates, it can fit against the inner wall of the battery compartment 13 to form a closed shielding of the inside of the battery compartment 13.

[0039] Example 2 Reference Figures 2 to 16 This is the second embodiment of the present invention, which is based on the previous embodiment. A protective shell 14 is fixedly connected to one side of the drive block 12. The drive block 12 is equipped with a trigger 15, which is connected to the motor control switch through an internal connecting rod. Pressing the trigger 15 can control the motor to start and stop, thereby controlling the cutting action of the shear blade 16. The protective shell 14 provides safety protection for the trigger 15 to prevent accidental activation of the electric shears and cause safety accidents. It also works in conjunction with the protective shell 14. A shear blade 16 is provided on one side of the drive block 12. The shear blade 16 includes a fixed blade fixed on the drive block 12 and a moving blade driven by the drive mechanism. The moving blade rotates around the connecting shaft under the drive of the motor and works with the fixed blade to cut the branches.

[0040] A battery component 24 is located on one side of the dovetail groove 22. The battery component 24 is the core power supply of the equipment. The battery component 24 includes a lithium battery body 24-1. A contact plate 24-2 is fixedly connected to one side of the lithium battery body 24-1. The size of the contact plate 24-2 is adapted to the size of the battery compartment 13 to ensure stable contact between the electrodes inside the battery compartment 13. A limiting block 24-3 is fixedly connected to one side of the contact plate 24-2. The limiting block 24-3 is a raised plastic material that serves as a positioning guide during battery installation, ensuring precise alignment between the contact plate 24-2 and the electrodes of the battery compartment 13, and preventing installation defects. Poor contact caused by misalignment: The length of contact plate 24-2 is slightly longer than the connection between contact plate 24-2 and lithium battery body 24-1. When lithium battery body 24-1 moves into battery compartment 13, contact plate 24-2 will first contact dustproof plate 23, thereby pushing dustproof plate 23 to rotate rotating column 26-1 and open double opening plate 21. When double opening plate 21 is opened enough for the connection between contact plate 24-2 and lithium battery body 24-1 to pass, the connection between contact plate 24-2 and lithium battery body 24-1 just reaches the end position of double opening plate 21.

[0041] A sliding groove 25 is provided on one side of the dovetail groove 22. The double-opening plate 21 is slidably disposed in the sliding groove 25. The length of the sliding groove 25 is slightly greater than the unfolded length of the double-opening plate 21. The sliding groove 25 constrains the movement trajectory of the double-opening plate 21, so that the double-opening plate 21 can only make straight opening and closing movements along the direction of the sliding groove, ensuring that the double-opening plate 21 is always in contact with the edge of the opening of the battery compartment 13 during the opening and closing process, and avoiding gaps that could allow dust to enter.

[0042] A driving component 26 is fixedly connected to the outer wall of the dustproof plate 23. The driving component 26 is a transmission structure that realizes the rotation of the dustproof plate 23. It includes a rotating column 26-1 fixedly connected to the outer wall of the dustproof plate 23. The rotation of the rotating column 26-1 can drive the rotation of the dustproof plate 23, providing support for the subsequent rotation of the dustproof plate 23. A first column groove 26-2 is opened on one side of the dovetail groove 22. A worm 26-3 is fixedly connected to one end of the rotating column 26-1. A worm plate 26-4 is fixedly connected to the outer wall of the worm 26-3. The worm 26-3 fixed to one end of the rotating column 26-1 is coaxial with the rotating column 26-1. The worm plate 26-4 on the outer wall of the worm has helical teeth with a reasonable tooth inclination angle, which can convert the rotational motion of the rotating column into linear driving force. The diameter of the rotating column 26-1 and the worm plate 26-4 have certain special settings. This creates a difference in the linear rotational speeds between the two components, causing the rotating column 26-1 to drive the worm gear 26-3, which in turn engages with the worm plate 26-4, thereby driving the double-opening plate 21 to move. A rotating groove 26-5 is provided on one side of the double-opening plate 21, and the worm plate 26-4 is positioned within this groove. The inner wall of the rotating groove 26-5 on one side of the double-opening plate 21 is machined with teeth that mesh with the worm plate 26-4. When the worm gear 26-3 rotates with the rotating column 26-1, the worm plate 26-4 interacts with the teeth in the rotating groove 26-5. Through gear meshing, the rotational motion of the worm gear 26-3 is converted into the linear motion of the double-opening plate 21 along the sliding groove 25. This linkage structure synchronizes the rotation of the dustproof plate 23 with the opening and closing of the double-opening plate 21, achieving coordinated control of the closing and opening of the battery compartment 13.

[0043] A pusher 17 is provided inside the battery compartment 13. The pusher 17 is mainly used by the operator to remove the lithium battery body 24-1 from the battery compartment 13 after the operator releases the latch lock. It includes a first spring groove 17-1 opened on one side of the dovetail groove 22. A first spring 17-2 is fixedly connected to one side of the first spring groove 17-1. When the lithium battery body 24-1 is fully inserted into the battery compartment 13, the first spring 17-2 provides elastic force to the lithium battery body 24-1. After the lock of the lithium battery body 24-1 is released, the elastic potential energy of the first spring 17-2 pushes the lithium battery body 24-1 a certain distance, thereby saving the operator's effort. A push block 17- is fixedly connected to one end of the first spring 17-2. 3. The pushing block 17-3 is in direct contact with the lithium battery body 24-1. The pushing block 17-3 has a second spring groove 17-4 inside. A second spring 17-5 is fixedly connected to one side of the second spring groove 17-4. A first inclined block 17-6 is fixedly connected to one end of the second spring 17-5. The second spring 17-5 cooperates with the first inclined block 17-6 to lock the position of the pushing block 17-3. The first inclined block 17-6 is set at an angle so that when the lithium battery body 24-1 squeezes the pushing block 17-3, the inclined end of the first inclined block 17-6 squeezes and contacts the port of the first spring groove 17-1, causing the second spring 17-5 to retract into the second spring groove 17-4, and at the same time, the pushing block 17-3 retracts into the first spring groove 17-1.

[0044] The first spring groove 17-1 has symmetrically formed latching grooves 17-7 on both sides, which provide a space for the first inclined block 17-6. An auxiliary component 18 is provided on one side of the latching groove 17-7, including a connecting rod groove 18-1 formed on one side of the latching groove 17-7. A connecting rod 18-2 is slidably arranged in the connecting rod groove 18-1. A limit groove 18-3 is formed at one end of the connecting rod groove 18-1. A second slider 18-4 is slidably arranged in the limit groove 18-3 and cooperates with the double-opening plate 21 and the connecting rod 18-2. The auxiliary component 18 is used for transmission between the double-opening plate 21 and the connecting rod 18-2. When the double-opening plate 21 is reset to both sides, the ends of the double-opening plate 21 are squeezed. Pressing one inclined end of the second slider 18-4 causes the second slider 18-4 to slide upward under the limit of the limiting groove 18-3. At this time, the other inclined end of the second slider 18-4 is pressed and engaged with the inclined end of the connecting rod 18-2, causing the connecting rod 18-2 to move under the limit of the connecting rod groove 18-1. At this time, one end of the connecting rod 18-2 presses against the first inclined block 17-6 in the buckle groove 17-7, causing the first inclined block 17-6 to squeeze the second spring 17-5 and thus disengage from the buckle groove 17-7. At this time, the limit of the pushing block 17-3 is unlocked. Under the elastic force of the first spring 17-2, the lithium battery body 24-1 is pushed a certain distance towards the outlet.

[0045] A reset component 27 is provided on one side of the first groove 26-2. The reset component 27 is used to realize the automatic closing of the dustproof plate 23. It includes a second groove 27-1 opened on one side of the first groove 26-2. The second groove 27-1 is a circular groove opened on the inner wall of the battery compartment 13. Its diameter is larger than the outer diameter of the torsion spring 27-2. The second groove 27-1 is provided with a torsion spring 27-2. One end of the torsion spring 27-2 is engaged in a slot in the inner wall of the second groove 27-1, and the other end is fixedly connected to the worm gear 26-3 and cooperates with the worm gear 26-3. When the dustproof plate 23 is pushed open by an external force, the rotating column 26-1 drives the worm gear 26-3 to rotate, causing the torsion spring 27-2 to undergo torsional deformation and store elastic potential energy. When the external force disappears, the elastic potential energy of the torsion spring 27-2 is released, driving the worm gear 26-3 to rotate in the opposite direction, causing the dustproof plate 23 to automatically reset to the closed position.

[0046] A clamping member 28 is provided on one side of the dovetail groove 22. The clamping member 28 is used to enhance the stability of the battery after installation. It includes a moving groove 28-1 opened on one side of the dovetail groove 22. The moving groove 28-1 provides sliding space for the moving block 28-2. The moving block 28-2 is slidably arranged in the moving groove 28-1. A first tooth 28-3 is fixedly connected to one side of the moving block 28-2. A second tooth 28-4 is fixedly connected to the outer wall of the rotating column 26-1 and cooperates with the first tooth 28-3. The first tooth 28-3 on one side of the moving block 28-2 is a linear tooth structure that meshes with the second tooth 28-4 on the outer wall of the rotating column 26-1. When the rotating column 26-1 rotates, the second tooth 28-4 drives the first tooth 28-3, causing the moving block 28-2 to move along the moving groove 28-1, thereby cooperating with subsequent actions to stably reinforce the lithium battery installation.

[0047] A third spring groove 28-5 is provided on one side of the moving groove 28-1. A third spring 28-6 is fixedly connected to one side of the third spring groove 28-5. An extrusion member 29 is provided at one end of the third spring 28-6. The third spring groove 28-5 is a cylindrical groove. One end of the third spring 28-6 is fixed to the bottom of the third spring groove 28-5, and the other end is connected to the extrusion member 29. In the initial state, the dustproof plate 23 of the third spring 28-6 is closed. The extrusion member 29 includes an extrusion block 29-1 fixedly connected to one end of the third spring 28-6. The end of the extrusion block 29-1 is made of nylon, which has a certain elasticity and wear resistance. An inclined groove 29-2 is provided in the extrusion block 29-1. An inclined block 29-3 is fixedly connected to the end of the moving block 28-2 and is connected to the inclined groove. 29-2 work together. When the moving block 28-2 moves under the tooth drive, the inclined block 29-3 slides along the inclined groove 29-2. Through the pressing action of the inclined block 29-3 and the inclined groove 29-2, the pressing block 29-1 moves down, thereby pressing against the lithium battery to prevent it from loosening or falling off during operation. After use, the pressing force between the inclined block 29-3 and the inclined groove 29-2 is released, and the third spring 28-6 returns to its original position to provide support for the next use. It should be noted that the rotating column 26-1 moves in conjunction with the moving block 28-2. When the lithium battery body 24-1 is fully inserted into the battery compartment 13, the pressing block 29-1 moves down and presses against the lithium battery body 24-1, thereby stabilizing and reinforcing the installation of the lithium battery body 24-1.

[0048] When in use, hold the lithium battery body 24-1 and align one side of the contact plate 24-2 with the opening direction of the battery compartment 13, so that the limiting block 24-3 is aligned with the limiting groove on the inner wall of the battery compartment 13. Push the lithium battery body 24-1 into the battery compartment 13. As the lithium battery is pushed in, the contact plate 24-2 will first contact the dustproof plate 23 at the end of the dovetail groove 22. Continue to apply the pushing force, and the contact plate 24-2 will push the dustproof plate 23 to rotate around the rotating column 26-1. At this time, the rotating column 26-1 fixed on the outer wall of the dustproof plate 23 will rotate in the first column groove 26-2, driving the worm 26-3 fixed at one end to rotate synchronously. The worm plate 26-4 on the outside of the worm 26-3 meshes with the teeth on the inner wall of the rotating groove 26-5 on one side of the double-opening plate 21, converting the rotational motion of the worm 26-3 into the linear motion of the double-opening plate 21, so that the double-opening plate 21 slides open to both sides along the sliding groove 25.

[0049] During the rotation of the rotating column 26-1, the second tooth 28-4 on its outer wall meshes with the first tooth 28-3 on one side of the moving block 28-2, driving the moving block 28-2 to move along the moving groove 28-1. The inclined block 29-3 at the end of the moving block 28-2 gradually slides into the inclined groove 29-2 in the pressing block 29-1. As the moving block 28-2 continues to move, the inclined block 29-3 and the inclined groove 29-2 press against each other, causing the pressing block 29-1 to compress the third spring 28-6 and move downward. When the lithium battery body 24-1 is fully inserted into the battery compartment 13, the contact plate 24-2 precisely connects with the electrode in the battery compartment 13. At this time, the double-opening plate 21 is opened to the maximum extent, and the connection between the contact plate 24-2 and the lithium battery body 24-1 reaches the end position of the double-opening plate 21. At the same time, the pressing block 29-1 moves down and presses against the lithium battery body 24-1, stabilizing the lithium battery.

[0050] Simultaneously, the end of the lithium battery body 24-1 contacts the pushing block 17-3 of the pushing member 17, and continues to apply a pushing force. The pushing block 17-3 retracts into the first spring groove 17-1, compressing the first spring 17-2. At this time, the inclined end of the first inclined block 17-6 in the pushing block 17-3 presses against the port of the first spring groove 17-1, forcing the second spring 17-5 to retract into the second spring groove 17-4. When the pushing block 17-3 is fully retracted into the first spring groove 17-1, the first inclined block 17-6 pops out under the elastic force of the second spring 17-5 and is locked into the buckle groove 17-7, completing the position locking of the pushing block 17-3 and completing the installation of the lithium battery. When the lithium battery is removed after the operation is completed, pull the lithium battery body 24-1 outward. The pushing force of the contact plate 24-2 on the dustproof plate 23 disappears, and the torsion spring 27-2 in the second column groove 27-1 releases its elastic potential energy, driving the worm gear 26-3 to rotate in the opposite direction. This causes the rotating column 26-1 and the dustproof plate 23 to reset, and the dustproof plate 23 re-fits against the inner wall of the battery compartment 13 to seal it. When the rotating column 26-1 rotates in the opposite direction, the moving block 28-2 moves in the opposite direction along the moving groove 28-1 through the tooth transmission. The inclined block 29-3 slides out of the inclined groove 29-2, and the third spring 28-6 pushes the pressing block 29-1 to reset and release the clamp. At the same time, the double-opening plate 21 closes towards the middle along the sliding groove 25. The end of the double-opening plate 21 presses the inclined end of the second slider 18-4 in the limiting groove 18-3, causing the second slider 18-4 to... -4 slides upward within the limiting groove 18-3, and its other inclined end presses against the inclined end of the connecting rod 18-2, pushing the connecting rod 18-2 to move within the connecting rod groove 18-1. One end of the connecting rod 18-2 presses against the first inclined block 17-6 within the latch groove 17-7, forcing the first inclined block 17-6 to squeeze the second spring 17-5 out of the latch groove 17-7, unlocking the limiting position of the pushing block 17-3. The first spring 17-2 within the first spring groove 17-1 releases its elastic force, and the pushing block 17-3 drives the lithium battery body 24-1 towards the outlet of the battery compartment 13, pushing the lithium battery a certain distance to facilitate easy removal by the operator. After the lithium battery is completely removed, the double-opening plate 21 returns to its initial closed state, and the pushing block 17-3 resets under the action of the first spring 17-2, ready for the next use.
