The working principle of the embodiment is as follows: when the telescopic pruning knife for gardens convenient to disassemble and assemble is used, firstly, the whole length of the device is adjusted according to the use requirement, the plug 14 is pulled out, then the extension handle 17 is pulled, the extension handle 17 slides in the slide way 22 arranged in the accommodating groove 21 through the slide block 23, meanwhile, the penetrating sleeve 15 fixedly connected with the extension handle 17 also slides on the handle 12, when the extension handle 17 slides to a proper position, the plug 14 sequentially penetrates through the penetrating sleeve 15 and the positioning hole 16 at the corresponding position on the handle 12, so that the drawing length of the extension handle 17 is limited, and then a user slides the rubber sleeve 19 to a proper position so as to take the device at the proper position according to the use habit of the user;

then the user pulls the protection block 20 again, so that the two ends of the protection block 20 can slide to the central position of the telescopic slot 29 in the sliding slot 30 through the rubber block 31, at this time, the protection block 20 can protrude out of the telescopic slot 29, then the user can pass the hand below the protection block 20 and hold the rubber sleeve 19, the arrangement not only can prevent the device from easily separating from the hand, but also can well avoid the collision of the two hands of the user when the handle 12 is rotated and attached, so as to play a good role in protection, then the user can open and close the handle 12 through the rotating shaft 13, so that the left blade 1 and the right blade 3 can be opened and closed under the driving of the handle 12, the tree branches to be cut are placed in the blade slot 4, then the left blade 1 and the right blade 3 are closed, the protruding section 2 can be matched with the blade slot 4 to cut the tree branches, the left blade 1 and the right blade 3 are provided with 3 groups of convex slices 2 and blade grooves 4 with different diameters, so that branches with different diameters can be cut off, and the reserved through holes 5 on the left blade 1 and the right blade 3 can play a role in reducing the whole weight of the device, so that a user can use the device more conveniently;

if the surface of a branch needs to be cut, the left blade 1 or the right blade 3 can be taken down from the handle 12, the left blade 1 and the right blade 3 are firstly in an open state, then the mounting block 11 can be rotated, the mounting block 11 can be taken down from the upper part of the handle 12, then the extension handle 17 and the abutting block 18 are rotated, corresponding threads are arranged below the inner part of the extension handle 17 and the outer part of the hidden rod 26, so that the hidden rod 26 can be drawn out from the extension handle 17, then the mounting block 11 is mounted in a thread groove 28 above the hidden rod 26, and the taken-down blade and the hidden rod 26 can form a new using device, so that the surface of the branch can be cut by using the flat blade 6;

if branches at a high position and in a horizontal state need to be cut in parallel, the extension handle 17 needs to be pulled out first, the mounting hole 24 and the connecting hole 25 below the extension handle can be completely exposed, then the elastic lugs 27 at two sides of the hidden rod 26 are pressed, the hidden rod 26 is inserted into the mounting hole 24, the elastic lugs 27 are released, the elastic lugs 27 can penetrate through the connecting hole 25 to be connected with the extension handle 17, at the moment, the hidden rod 26 and the extension handle 17 can be in a mutually vertical and fixed state, then a user can lift the device to cut the branches at the high position, and the arm of the user can be better stressed by the mode, so that the branches at the high position can be conveniently cut;

when the device is not used, other parts need to be restored to be in the original state, then the bolt 10 is taken off by rotation, at the moment, the bolt 10 is not fixed, the connecting block 7 can be overturned in the rotating groove 9 through the connecting shaft 8 until the left blade 1 and the right blade 3 can be opposite to the back surface of the handle 12, at the moment, the left blade 1 and the right blade 3 are overturned by 180 degrees through the connecting block 7, then the bolt 10 is used for fixing the connecting block 7, because the outer sides of the left blade 1 and the right blade 3 are both provided with the flat cutting edge 6, therefore, when the device is not used or stored, the left blade 1 and the right blade 3 need to be covered and protected by the protective sleeve, so as to avoid accidents, the folded device provides convenience for the user to carry, which is the use process of the whole device, and those not described in detail in this specification are well within the skill of those in the art.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
