[0022] The utility model will be described further in detail in combination with the drawings and specific embodiments: refer to Figures 1-5 The utility model discloses a garden tool handle folding mechanism, including first pipe fitting 1 and second pipe fitting 2, first pipe fitting 1 and second pipe fitting 2 one end one side are hinged together, and first pipe fitting 1 and second pipe fitting 2 can be folded to each other, wherein the angle of the axis of first pipe fitting 1 and the axis of second pipe fitting 2 changes in the range of 10 degrees-180 degrees, when the axis of first pipe fitting 1 and the axis of second pipe fitting 2 are in a straight line, i.e. the angle between first pipe fitting 1 and second pipe fitting 2 is 180 degrees, the end surface of first pipe fitting 1 and the end surface of second pipe fitting 2 are pressed and contacted, and a locking part is further arranged on the hinged end of first pipe fitting 1 and second pipe fitting 2, the locking part is used to lock first pipe fitting 1 and second pipe fitting 2 when the axis of first pipe fitting 1 and the axis of second pipe fitting 2 are in a straight line, so that first pipe fitting 1 and second pipe fitting 2 do not rotate any more.

[0023] The hinged part includes first rotating part 11, second rotating part 21 and pin shaft, the first rotating part 11 is located on one side of one end of first pipe fitting 1, and first rotating part 11 is provided with first shaft hole 111, the second rotating part 21 is located on one side of one end of second pipe fitting 2, and second rotating part 21 is provided with second shaft hole 211, the axis of first shaft hole 111 on first pipe fitting 1 and the axis of second shaft hole 211 on second pipe fitting 2 are aligned, the pin shaft is simultaneously arranged in first shaft hole 111 and second shaft hole 211, and the pin shaft is positioned by nut or pin, so that the pin shaft cannot be limited and locked in first shaft hole 111 and second shaft hole 211, and then first pipe fitting 1 and second pipe fitting 2 are hinged together.

[0024] The axis of first shaft hole 111 is flush with the side end surface of first pipe fitting 1, the axis of second shaft hole 211 is flush with the side end surface of second pipe fitting 2, and then when the axis of first pipe fitting 1 and the axis of second pipe fitting 2 are in a straight line, the end surface of first pipe fitting 1 and the end surface of second pipe fitting 2 are pressed and contacted.

[0025] The end surface of second rotating part 21 of second pipe fitting 2 is provided with annular positioning ring 24, and the first pipe fitting 1 that is pressed and contacted is provided with positioning slot hole that is matched therewith, when the end surface of first pipe fitting 1 and the end surface of second pipe fitting 2 are pressed and contacted, positioning ring 24 is located in the positioning slot hole of first pipe fitting 1, and then first pipe fitting 1 and second pipe fitting 2 are positioned and connected between them, and the shaking gap between them is reduced.

[0026] The locking part includes a wrapping part 12 extending beyond the end face of the first pipe 1. A first locking hole 121 is provided on the wrapping part 12, and a deformation groove 122 is provided on the wrapping part 12 along the axial direction of the first pipe 1. The deformation groove 122 divides the wrapping part 12 into left and right parts. The second pipe 2 has through holes 23 extending through it on both sides. At the same time, a reinforcing block 22 is arranged around the through hole 23 to strengthen the pipe wall, so that the through hole 23 passes through the reinforcing block 22. The cross-sectional area of ​​the reinforcing block 22 is less than 1 / 2 of the cross-sectional area of ​​the inner hole of the second pipe 2, so that the reinforcing block 22 will not block the end face of the second pipe 2, allowing the control line of the garden tool to pass normally.

[0027] When the end face of the first pipe fitting 1 presses against the end face of the second pipe fitting 2, the first locking hole 121 on the wrapping component 12 is aligned with the axis of the through hole 23 on the second pipe fitting 2. The wrapping component 12 presses against the outer wall of one end of the second pipe fitting 2. At this time, the threaded component passes through the first locking hole 121 and the through hole 23, and is locked with the nut. During the locking process, the wrapping component 12, which is divided into left and right halves, moves closer to the deformation groove 122, and the width of the deformation groove 122 decreases. At the same time, the wrapping component 12 is pressed against the outer wall of the second pipe fitting 2, thereby locking the second pipe fitting 2 and the first pipe fitting 1 together and preventing wobbling. When clamped, the reinforcing block 22 provides support for the second pipe fitting 2, so that the second pipe fitting 2 does not deform.

[0028] The first locking hole 121 on the package 12 has stepped holes at both ends. One end has a circular stepped hole, and the other end has a stepped hole that matches the nut. The threaded part is a round head bolt. The round head of the bolt can be recessed into the circular stepped hole, while the nut is recessed into the nut matching stepped hole to avoid the threaded part being exposed and thus avoid accidental contact with the threaded part.

[0029] In this embodiment, both the first pipe 1 and the second pipe 2 are circular. Therefore, the inner wall of the wrapping 12 is designed to be circular, and the diameter of the arc is consistent with the outer diameter of the second pipe 2, so as to fit the second pipe 2.

[0030] The first pipe 1 and the second pipe 2 can also be polygonal. When deformed, the inner wall of the wrapping 12 is also not polygonal, so as to match the shape of the second pipe 2.

[0031] The other end of the first pipe fitting 1 and the second pipe fitting 2 is provided with a connecting part, which is used to connect and lock with the rod-shaped long rod on the garden tool. The connecting part includes a locking lug 14, and a second deformation groove 141 is opened on the locking lug 14 along the axis of the pipe fitting. At the same time, a second locking hole 142 perpendicular to the second deformation groove 141 is also opened on the locking lug 14. The first pipe fitting 1 and the second pipe fitting 2 are both hollow pipe fittings. The end of the first pipe fitting 1 or the second pipe fitting 2 with the connecting part is sleeved on the end of the handle long rod that is matched. The bolt is passed through the second locking hole 142, and then the locking lug 14, which is divided into two by the second deformation groove 141, is brought closer to each other, thereby reducing the width of the second deformation groove 141, and thus locking the first pipe fitting 1 or the second pipe fitting 2 onto the handle long rod.

[0032] The positioning ring 24 is 2-4 mm higher than the end face of the second pipe 2. At the same time, the deformation groove 122 and the second deformation groove 141 provide clearance space when the positioning ring 24 rotates into the positioning groove of the first pipe 1, so that it will not touch the end wall of the first pipe 1.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
