[0030] The functional assembly 6 includes the piston cylinder 601 fixedly installed in the inner end of the knife arm 1, the piston cylinder 601 is slidably installed with the matched piston 605, the piston cylinder 601 is provided with the cambered head 602 at the opening, the cambered head 602 is fixedly connected with the limit block 603 at the end close to the piston 605, and the outer diameter of the limit block 603 is greater than the inner diameter of the piston cylinder 601, the limit block 603 and the piston 605 are fixedly connected with the extension rod 604, and the piston 605 and the bottom wall of the piston cylinder 601 are fixedly connected with the compression spring 606, when the blade 2 is combined to carry out pruning work, a pair of functional assemblies 6 will abut and extrude each other, the cambered head 602 moves inward, indirectly pushes the piston 605 to extrude the compression spring 606, realizes certain elastic buffering effect, and at the same time, a pair of blades 2 can be independently separated by relying on the elastic force of the compression spring 606 after the user removes the holding force, which is convenient for the next pruning action.

[0031] The upper end of the piston cylinder 601 is fixedly installed with a jet pipe 607 in communication, and the jet pipe 607 is open away from the end of the piston cylinder 601, and is fixedly connected with a filter screen 608, the piston 605 is moved inward to extrude the compression spring 606, and at the same time, the gas in the piston cylinder 601 is also extruded, so that the gas is sprayed from the jet pipe 607 to the blade 2, and the dust and impurities on the surface of the blade 2 can be cleaned, and when the piston 605 is reset to inhale, the filter screen 608 can be blocked to avoid blockage after entering the inside.

[0032] The control switch 11 includes a self-locking button switch and a self-resetting button switch. The self-locking button switch can be pressed to keep the electromagnet 10 working, thereby continuously adsorbing the magnet block 9, so that a pair of blades 2 are in a folding state, which is convenient for carrying in a non-use state. The self-resetting button switch can be pressed to release and then be powered off. When force is needed during pruning, the self-resetting button switch can be pressed to temporarily power on the electromagnet 10 to adsorb the magnet block 9, thereby assisting the user in pruning, and achieving the purpose of saving labor.

[0033] The handle 7 is fixedly connected to the outer end of the anti-slip sleeve 4 corresponding to the magnet block 9, and the inner end of the handle 7 is covered with a silica gel pad 8. The handle 7 is convenient for the user to hold and carry, and can improve the control effect of the anti-slip sleeve 4 during pruning, avoiding accidental hand-off under the magnetic attraction of the electromagnet 10.

[0034] The threaded knob 5 is screw-mounted on the front end of the anti-slip sleeve 4 corresponding to the electromagnet 10, and is internally installed with a power supply, which is electrically connected with the control switch 11. The control switch 11 is used to supply power to the electromagnet 10, and can be replaced or charged by unscrewing the threaded knob 5.

[0035] When in use, when the user carries or shifts the pruning site, the electromagnet 10 is always powered to attract the magnet block 9 through the self-locking button switch, so that the pair of blades 2 and the blade arm 1 remain in the folded posture, at this time, the overall size of the scissors is small, easy to carry, and convenient for the user to carry by the handle 7. When pruning work is performed, the self-locking button switch is pressed again to make the electromagnet 10 lose power, at this time, the user can put his fingers through the handle 7, press the other anti-skid sleeve 4 with the thumb, and approach the control switch 11. When encountering relatively laborious pruning work, the electromagnet 10 is temporarily powered to attract the magnet block 9 through the self-recovery button switch, the user can prune by taking advantage of the force, which is used to save labor or cope with some laborious pruning work, and will not affect the normal unfolding of the blades 2. In addition, the functional assembly 6 can play a role of elastic buffering, so that the scissors are relatively stable during pruning work, and can also provide elastic reset function, assist the pair of blades 2 to separate to perform the next pruning work, improve the pruning efficiency, and the air jet pipe 607 can clean the dust and foreign matters on the surface of the blades 2.

[0036] It should be noted that the specific connection mode of the circuit in the embodiment is as follows:

[0037] Power supply: The power supply is installed in the anti-skid sleeve 4, is fixed by the screw knob 5, and is convenient for replacement or charging. The power supply provides the required direct current voltage for the entire circuit system.

[0038] Self-locking button switch: One end of the self-locking button switch is connected with the positive pole of the power supply, and the other end is connected with one end of the electromagnet 10 through a wire. When the self-locking button switch is pressed, the circuit is closed, the power supply supplies power to the electromagnet 10, the electromagnet 10 generates magnetism and attracts the magnet block 9, so that the blades 2 remain in the folded state. When the button is pressed again, the circuit is disconnected, the electromagnet 10 loses power, and the blades 2 can be separated.

[0039] Self-recovery button switch: One end of the self-recovery button switch is also connected with the positive pole of the power supply, but the other end is connected with the electromagnet 10 through a parallel circuit. The parallel circuit also includes a normally closed contact connected in series with the self-locking button switch (when the self-locking button switch is in the disconnected state, the contact is closed). In this way, when the self-recovery button switch is pressed, no matter whether the self-locking button switch is in the closed state or not, the electromagnet 10 will be temporarily powered and attract the magnet block, realizing the labor-saving pruning action. After the self-recovery button switch is released, the circuit is immediately disconnected, and the electromagnet 10 loses power.

[0040] Electromagnet 10: One end of the electromagnet 10 is connected with the above two switches, and the other end is connected with the negative pole of the power supply through a wire. When the electromagnet 10 is powered, it generates magnetism and attracts the magnet block 9; when it loses power, the magnetism disappears, and the magnet block 9 is separated from the electromagnet 10.

[0041] Protection circuit: in order to prevent the circuit short circuit or overload, can be added fuse or current limiting resistor between the power supply and switch protection element.

[0042] The above merely the preferred specific embodiments of the present application; but the scope of protection of the present application is not limited to this. Any skilled in the art of the technical range disclosed by the present application, according to the technical scheme of the present application and its improvement concept to replace or change, should be covered within the scope of protection of the present application.
