Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] like Figure 1-5 As shown, a movable and adjustable garden pruning device includes high branch shears 100, wherein the high branch shears 100 include scissors 101, a pull rope 102 for controlling the opening and closing of the scissors 101, and a telescopic rod 103 connected to the handle of the scissors 101, the high branch shears 100 are connected to an operating table 400, and a positioner 200 for controlling the angle of connection of the high branch shears 100 to the operating table 400 is provided on the operating table 400, and a moving component 300 for controlling the movement of the operating table 400 is connected to the bottom of the operating table 400.

[0022] Working principle: Move the operating table 400 through the moving component 300, and then move the high branch shears 100 to a suitable working place, adjust the angle of the high branch shears 100 connected to the operating table 400 through the positioner 200, and then control the scissors 101 connected to the telescopic rod 103 to be at a suitable angle, so that the high branches that need to be pruned can be pruned, and pull the pull rope 102 to control the scissors 101 to prune the high branches.

[0023] Preferably, the mobile component 300 includes a tripod 301 and a universal wheel 302 connected to the bottom of the tripod 301. The mobile component 300 facilitates the movement of the high-branch shears 100 without manual hand-held movement. The tripod 301 is preferably a height-adjustable tripod, which is convenient for adjusting the height of the operating table 400 and improving the comfort of use of the device.

[0024] More preferably, the mobile assembly 300 also includes a locking piece 303 for locking the rolling of the universal wheel 302. The locking piece 303 is arranged on the universal wheel 302. The locking piece 303 can be locked by a pin connection. Since the use environment of the high branch shears 100 may be located on a slope, the mobile assembly 300 with the universal wheel 302 can be locked by the locking piece 303, thereby improving the versatility of the device.

[0025] Preferably, the positioner 200 includes a hinge frame 201 hinged to the non-end of the telescopic rod 103 and an arc-shaped slide groove 202 slidably connected to the end of the telescopic rod 103, the hinge frame 201 is fixed to the operating table 400, and both the hinge frame 201 and the telescopic rod 103 are penetrated with a hinge hole 105, and a hinge shaft is penetrated in the hinge hole 105, and nuts are detachably provided at both ends of the hinge shaft, and the arc-shaped slide groove 202 is fixed to the operating table 400 through a fixing frame 204, and a plurality of pairs of positioning holes 203 with internal threads are penetrated in the arc-shaped slide groove 202, and bolts with external threads are provided in the positioning holes 203, and the bolts are threadedly matched with the positioning holes 203, and the bolts are rotated to be located in the positioning holes 203. The bolt clamps the telescopic rod 103 at one end away from the scissors 101, which is used to control the angle of the high branch shears 100 connected to the operating table 400. The two ends of the arc-shaped slide groove 202 should be provided with limit members to prevent the telescopic rod 103 from falling off, and it is preferably arranged as a detachable plug-in baffle. After the end of the telescopic rod 103 is slidably connected to the arc-shaped slide groove 202, the telescopic rod 103 is hinged in the hinge frame 201 through the hinge shaft and the nut on the hinge shaft. At this time, the telescopic rod 103 is rotated and fixed by bolts at different heights. The angle of the high branch shears 100 connected to the operating table 400 can be controlled. The positioner 200 can control the angle of the high branch shears 100 connected to the operating table 400, but is not limited to the above-mentioned method.

The operating table 400 can be driven to rotate by shaking the adjusting crank handle 404. Compared with unlocking the universal wheel 302 and then rotating the tripod 301, the operating steps are simple, there is no need to frequently unlock and lock the universal wheel 302, the angle adjustment accuracy is higher, and the worm gear and worm gear cooperation mode is self-locking, which can prevent the high branch shears 100 from rotating due to the rotation of the rotating shaft 401 during operation, thereby improving the safety of the device, and the self-locking function can be achieved by setting the lead angle of the worm gear to be smaller than the equivalent friction angle between the meshing gear teeth.

[0027] More preferably, the telescopic rod 103 is provided with an anti-skid pad 104 at the connection between the telescopic rod 103 and the bolt. The material of the anti-skid pad 104 can be rubber, such as PVC. By providing the anti-skid pad 104, the friction between the bolt and the telescopic rod 103 can be increased, the positioning effect of the locator 200 can be enhanced, and the stability of the device can be improved.

[0028] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
