[0015] Figure 4 It is a structural schematic diagram of a rotary self-locking component. DETAILED DESCRIPTION

[0016] like Figure 1-4 As shown, a manual branch bending tool comprises a first branch bending arm 1 and a second branch bending arm 2 of different lengths, one end of the first branch bending arm 1 is connected to a vertically distributed sleeve 1a, one end of the second branch bending arm 2 is connected to a vertically distributed rotating shaft 2a, and the other ends of the first branch bending arm 1 and the second branch bending arm 2 are both provided with a hand-held portion 9, on which an anti-slip sleeve 9a is provided.

[0017] The first and second bending branch arms 1 and 2 are correspondingly provided with first and second slide rails 3 and 3b distributed along the length direction thereof, and the lengths of the first and second slide rails 3 and 3b are also different.

[0018] Corresponding sliders 3a are provided on both slide rails, and locking pins (not shown in the figure) are provided on the sliders 3a. According to the actual conditions such as the size of the branches to be bent and the curvature to be bent, the sliders 3a are fixed to the appropriate positions on the slide rails 3 by the locking pins, and the vertically distributed branch bending rods 5 are connected to the sliders 3a.

[0019] The rotating shaft 2a is inserted into the sleeve 1a, and a bearing is sleeved on its upper end and forms a fitting connection with the inner wall of the sleeve 1a through the bearing (not shown in the figure), and a rotating self-locking component 4 is used to form a fitting connection with the sleeve 1a at its lower end.

[0020] The rotating self-locking assembly 4 comprises: a reduced diameter portion 4a is provided at the lower end of the rotating shaft 2a, and a pair of pawls 4b are evenly distributed on the annular end surface formed by the reduced diameter portion 4a.

[0021] An annular groove 4c coaxially distributed with the diameter reduction portion 4a is provided on the inner wall of the sleeve 1a, and a coaxially distributed liner ring 4d is installed in the annular groove 4c. A circle of extruded teeth 4e corresponding to the ratchet 4b is evenly distributed on the inner wall of the liner ring 4d. The overall structure of the entire rotating self-locking assembly 4 is consistent with the bicycle flywheel and is a prior art, which will not be described in detail here. The rotating shaft 2a can only rotate in one direction in the sleeve 1a through the rotating self-locking assembly, and a hand-held portion 9 is provided at the other end of the first bending arm 1 and the second bending arm 2.

[0022] An anti-slip cover 9a is sleeved on the hand-held portion 9. A flexible buffer cover 5a is sleeved on the sleeve 1a and the bent branch rod 5.

[0023] Working process:

[0024] First, according to the diameter of the branch 10 of the landscape tree to be bent, the sliders 3a on the first bending arm 1 and the second bending arm 2 are moved to the appropriate position and then locked, and then one of the bending arms is rotated so that the first bending arm 1 and the second bending arm 2 are both moved to one side of the sleeve 1a, and then the branch 10 is inserted between the sleeve 1a and the bending rod 5 on the first bending arm 1 and the second bending arm 2, and then the first bending arm 1 and the second bending arm 2 are manually rotated to bend the branch 10 to a suitable curvature, and then the shape of the branch 10 is fixed by wire or cable tie. During the fixing process, due to the existence of the rotating self-locking component, after the first bending arm 1 and the second bending arm 2 are rotated into place, even if the staff lets go, the first and second bending arms will not rotate in the opposite direction due to the reaction force of the branch, so that the staff can complete the branch bending and fixing operations after bending.

[0025] After the branch is fixed, adjust the position of the slider on the second branch bending arm again so that the first branch bending arm can rotate one circle (the length of the first branch bending arm is smaller than that of the second branch bending arm), and then move to the same side of the second branch bending arm 2 again, that is, the starting state of the work (the first branch bending arm 1 and the second branch bending arm 2 are both moved to one side of the sleeve 1a), and then the next branch bending operation can be carried out.
