[0051] Example 1

[0052] according to Figure 1-3As shown, the utility model provides an electric fruit and flower thinner with adjustable gap, which can be used to thin flowers or fruit clusters, and fruits, and select the appropriate fruit thinning period for different plants. It includes a first base 10 and a second base 20, and the first base 10 and the second base 20 are rotatably connected at a fulcrum 8 in the middle. The fulcrum 8 includes a support shaft 81 and an axis hole 82, as shown in FIG. Figure 2 As shown, an axial hole 82 is opened in the middle of the first base 10 and the second base 20, and a support shaft 81 passes through the axial hole 82 to form a rotation fulcrum 8 of the first base 10 and the second base 20; a first clamp arm 2 is provided at the front of the first base 10, and a first handle 3 is provided at the rear thereof; a second clamp arm 4 is provided at the front of the second base 20, and a second handle 6 is provided at the rear thereof; a roller 5 is provided on each of the first clamp arm 2 and the second clamp arm 4, and the roller 5 is driven by a motor; when the first handle 3 and the second handle 6 are closed, the plant passes between the two rollers 5.

[0053] The first pliers arm 2 includes a lower shell 21 and a lower shell cover 22, wherein a motor 44 is disposed in the lower shell 21 and the lower shell cover 22; the second pliers arm 4 includes an upper shell 41 and an upper shell cover 42, wherein a motor 44 is disposed in the upper shell 41 and the upper shell cover 42;

[0054] An upper guard plate 43 is provided on the upper shell cover 42, and a lower guard plate 23 is provided on the lower shell cover 22. The upper guard plate 43 and the lower guard plate 23 are arranged on the outside of their corresponding rollers 5. The upper guard plate 43 and the lower guard plate 23 are semicircular, which can prevent plant branches, leaves, weeds, etc. from being pulled into the middle of the roller.

[0055] Furthermore, in order to prevent excessive fruit / flower thinning, the distance between the two rollers 5 needs to be flexibly adjusted according to the different plant varieties and the size of the flowers and fruit ears. For smaller fruit ears / flowers, the distance between the two rollers 5 should be smaller; for larger fruit ears / flowers, the distance between the two rollers 5 should be larger. Furthermore, the electric fruit and flower thinner also includes a gap adjustment device, which is used to adjust the gap between the first clamp arm 2 and the second clamp arm 4 when they are closed, thereby adjusting the distance between the two rollers 5.

[0056] like Figure 25-6, in the first embodiment of the present invention, an adjusting knob 1 is provided between the first base 10 and the second base 20. The adjusting knob 1 is fixedly connected to the second base 20 and slidably connected to the first base 10. By changing the position of the adjusting knob 1 on the second base 20, the rotation stroke of the first base 10 relative to the second base 20 is adjusted, thereby adjusting the size of the opening between the first clamp arm 2 and the second clamp arm 4. Specifically, a first arc-shaped hole 101 is provided on the first base 10, and a second arc-shaped hole 201 is provided at a corresponding position on the second base 20. The adjusting knob 1 passes through the first arc-shaped hole 101 and the second arc-shaped hole 201; the adjusting knob 1 includes, from top to bottom, a knob head 11, a limiting plate 12 and an adjusting stud 13. The limiting plate 12 is slidably connected to the first arc-shaped hole 101, and the adjusting stud 13 passes through the second arc-shaped hole 201 and is threadedly connected to the adjusting nut 14. Tighten the adjusting screw 13 to fix the adjusting knob 1 on the second base 20; when the position of the adjusting knob 1 needs to be changed, loosen the adjusting knob 1 by turning the knob head 11 with your finger, and the adjusting screw 13 can move in the second arc-shaped hole 201. When the adjusting screw 13 moves to the uppermost position of the second arc-shaped hole 201, the first clamp arm 2 and the second clamp arm 4 cannot be completely closed, and the opening distance between the two is maximized. The electric fruit and flower thinner can be used to thin fruit / flowers for larger fruit clusters / flowers;

[0057] When the adjusting stud 13 moves to the bottom of the second arc-shaped hole 201, the first clamp arm 2 and the second clamp arm 4 can be completely closed, and the opening distance between the two is minimized. The electric fruit and flower thinner can be used to thin fruit / flowers for smaller fruit clusters / flowers.

[0058] Further, such as Figure 4 As shown, a spring 7 is provided between the first handle 3 and the second handle 6. The spring 7 is a compression spring, which can provide elastic potential energy for the first handle 3 and the second handle 6 to open. After each fruit thinning / flower thinning operation is completed, the first handle 3 and the second handle 6 can automatically open under the action of the spring 7.

[0059] Furthermore, in order to avoid the need to continuously press the first handle 3 and the second handle 6 during the process of thinning fruits / flowers, a locking block 9 is rotatably connected to the first base 10, and a locking notch 202 is provided on the second base 20. The locking block 9 can be inserted into the locking notch 202. At this time, the first handle 3 and the second handle 6 cannot automatically open under the action of the spring 7, so as to prevent the first handle 3 and the second handle 6 from automatically opening before the fruit / flower thinning is completed. A torsion spring is also provided on the locking block 9, which applies pressure to the locking block 9 to lock it. The locking block 9 is automatically inserted into the locking notch 202 when the operator presses the first handle 3 and the second handle 6 when thinning fruits / flowers. At this time, there is no need to continue to press the first handle 3 and the second handle 6 and they will not bounce out. After the fruit / flower thinning operation is completed, the locking block 9 is pulled open by the fingers and the locking block 9 is removed from the locking notch 202. At this time, under the action of the spring 7, the first handle 3 and the second handle 6 can automatically open to prepare for the next fruit / flower thinning operation.

[0060] How it works

[0061] First, the plant to be thinned out is positioned between the opened first clamp arm 2 and the second clamp arm 4, and the first handle 3 and the second handle 6 are pressed by hand to close the first clamp arm 2 and the second clamp arm 4, and the plant passes through the two rollers 5. When the first clamp arm 2 and the second clamp arm 4 are closed in place, the locking block 9 is automatically inserted into the locking notch 202. At this time, there is no need to continue pressing the first handle 3 and the second handle 6 and they will not bounce off; then, the motor 44 switch is turned on, and the two rollers 5 rotate. In the process of pulling the electric fruit and flower thinner, some of the flowers or fruit ears passing through the rollers 5 are knocked off; after this fruit thinning / flower thinning operation is completed, the locking block 9 is pulled open by fingers, and the locking block 9 is removed from the locking notch 202. At this time, under the action of the spring 7, the first handle 3 and the second handle 6 are automatically opened to prepare for the next fruit thinning / flower thinning operation.

[0062] Example 2

[0063] The difference between this embodiment and the first embodiment is only the difference in the gap adjustment device. Figure 7-8 The gap adjustment device includes a first adjusting screw 1-1a, which is movably provided on the side wall of the first clamp arm 2 or the second clamp arm 4. For example, the first adjusting screw 1-1a is threadedly connected to the side wall of the first clamp arm 2 or the second clamp arm 4. When the first clamp arm 2 and the second clamp arm 4 are closed, the top end of the first adjusting screw 1-1a contacts the side wall of the second clamp arm 4 or the first clamp arm 2 opposite thereto. Due to the presence of the first adjusting screw 1-1a, the first clamp arm 2 and the second clamp arm 4 cannot be completely closed.

[0064] Furthermore, in order to lock the position of the first adjusting screw 1-1a, that is, when the operator does not want the first adjusting screw 1-1a to rotate again after adjusting the gap between the first clamp arm 2 and the second clamp arm 4, a first adjusting nut 1-1b is also connected to the first adjusting screw 1-1a, and the first adjusting nut 1-1b is used to lock the position of the first adjusting screw 1-1a; tighten the first adjusting nut 1-1b, and tighten the first adjusting screw 1-1a through the first adjusting nut 1-1b, so that the first adjusting screw 1-1a cannot rotate relatively.

[0065] Example 3

[0066] The difference between this embodiment and the first and second embodiments is only the difference in the gap adjustment device. Figure 9 The gap adjustment device includes an adjustment fixing block 1-2a, a second adjustment screw 1-2c and an adjustment limit block 1-2d, the adjustment fixing block 1-2a is fixedly set on the lower surface of the first clamp arm 2 or the second clamp arm 4, and the adjustment limit block 1-2d is set on the lower surface of the second clamp arm 4 or the first clamp arm 2; such as: the adjustment fixing block 1-2a is fixedly set on the lower shell 21, and the adjustment limit block 1-2d is set on the upper shell 41; or the adjustment fixing block 1-2a is fixedly set on the upper shell 41, and the adjustment limit block 1-2d is set on the lower shell 21; the second adjustment screw 1-2c is threadedly connected to the adjustment fixing block 1-2a, and when the first clamp arm 2 and the second clamp arm 4 are closed, the top of the second adjustment screw 1-2c contacts the adjustment limit block 1-2d opposite to it.

[0067] Furthermore, in order to lock the position of the second adjusting screw 1-2c, that is, when the operator does not want the second adjusting screw 1-2c to rotate again after adjusting the gap between the first clamp arm 2 and the second clamp arm 4, a locking nut 1-2b is also connected to the second adjusting screw 1-2c, and the locking nut 1-2b is used to lock the position of the second adjusting screw 1-2c; tighten the locking nut 1-2b, and tighten the second adjusting screw 1-2c through the locking nut 1-2b, so that the second adjusting screw 1-2c cannot rotate relatively.

[0068] By arranging the gap adjustment device on the lower surface of the first clamp arm 2 and the second clamp arm 4, the first clamp arm 2 and the second clamp arm 4 can be completely closed when necessary, thereby increasing the adjustable range of the gap between the first clamp arm 2 and the second clamp arm 4.

[0069] Example 4

[0070] On the basis of the first to third embodiments, this embodiment further provides a battery 45 to power the motor of the electric fruit and flower thinner, so that the operation of the electric fruit and flower thinner does not require an external power supply, thereby improving the convenience of the operation of the electric fruit and flower thinner. Figure 10-11 As shown, a battery 45 is provided on the upper shell 41 and / or in the lower shell 21 (a set of batteries can be provided on the upper shell 41 or in the lower shell 21, or a set of batteries can be provided on the upper shell 41 and in the lower shell 21). A charging interface 46 is provided to facilitate charging of the battery 45. A switch 47 is provided to control the working state of the electric fruit and flower thinner. The battery 45 is electrically connected to the motor 44, the switch 47 and the charging interface 46.

[0071] Furthermore, in order to prevent a hard collision when the first clamp arm 2 and the second clamp arm 4 are closed, a protrusion 1-3 is provided on the side wall of the first clamp arm 2 and / or the second clamp arm 4. The protrusion 1-3 can be hemispherical and can be made of soft plastic or silicone material.
