[0028] The utility model also provides a garden tool, comprising: a main body, a cutting device, a rod fixedly connecting the main body and the cutting device, and the above-mentioned auxiliary handle, the main body and the cutting device are respectively arranged at opposite ends of the rod, and the auxiliary handle is movably arranged on the rod.

[0029] The following is a detailed description of the implementation details of the auxiliary handle of this embodiment. The following content is only provided for ease of understanding and is not necessary for implementing this solution.

[0030] See also Figures 1 to 3 The auxiliary handle 100 of this embodiment is applied to the rod 200. The auxiliary handle 100 includes a handle body 110, a limiter 120, and a locking assembly 130. The handle body 110 includes a gripping portion 111 and a mounting portion 112 connected to each other. The mounting portion 112 abuts the rod 200. The gripping portion 111 is located on the side of the mounting portion 112 facing away from the rod 200 and is used to provide a gripping space. The limiter 120 is located on the side of the mounting portion 112 facing away from the gripping portion 111 and is detachably connected to the mounting portion 112. The rod 200 is clamped between the limiter 120 and the mounting portion 112. The locking assembly 130 includes an adjusting member 131 and a locking member 132. The adjusting member 131 is movably disposed on the mounting portion 112. The locking member 132 is located between the mounting portion 112 and the limiter 120 and is movable relative to the mounting portion 112. The adjusting member 131 is used to drive the locking member 132 to move, so that the locking member 132 and the limiting member 120 clamp the rod 200 to fix the position of the handle body 110 .

[0031] Such a setting can not only achieve quick tightening and loosening of the auxiliary handle 100, but also ensure the stability of the combination of the auxiliary handle 100 and the rod 200. In particular, the use of the limit member 120 and the locking member 132 to clamp and tighten the rod 200 can reduce the wear between different components, thereby improving the durability of the auxiliary handle 100.

[0032] See also Figure 2 In some embodiments, the grip portion 111 and the mounting portion 112 are both C-shaped. The mounting portion 112 is smaller than the grip portion 111. The two ends of the mounting portion 112 are connected to the two ends of the grip portion 111 in a one-to-one correspondence. The mounting portion 112 is recessed toward the interior of the grip portion 111, forming a nearly concave annular structure. The recessed space of the mounting portion 112 is used to accommodate the rod 200. This arrangement allows the rod 200 to be quickly and conveniently assembled into the auxiliary handle 100 from one side of the mounting portion 112.

[0033] Furthermore, the limiting member 120 is also located in the recessed space of the mounting portion 112 . Specifically, the limiting member 120 can be installed on the same side as the rod 200 after the mounting portion 112 is installed, and can clamp the rod 200 together with the mounting portion 112 .

[0034] Alternatively, the rod 200 may be in a cylindrical, polygonal, or elliptical shape, depending on actual needs. This embodiment uses a cylindrical shape as an example. In this case, to enhance the stability of the auxiliary handle 100 after connection to the rod 200, a third curved surface may be provided on the mounting portion 112, and a first curved surface may be provided on the stopper 120. When the mounting portion 112 and the stopper 120 clamp the rod 200, the first and third curved surfaces engage to form a circular through hole that aligns with the sidewall of the rod 200.

[0035] It is understandable that, since the locking member 132 and the limiting member 120 also cooperate with and clamp the rod 200 , the locking member 132 is provided with a second curved surface, and the second curved surface also matches the side wall surface of the rod 200 .

[0036] See also Figure 2 and Figure 3 In some embodiments, the position-limiting member 120 includes a receiving portion 122 and a plurality of fixing protrusions 121. The fixing protrusions 121 are disposed on opposite sides of the position-limiting member 120. The mounting portion 112 is provided with a plurality of oppositely disposed fixing grooves 112a. The fixing protrusions 121 are correspondingly inserted into the fixing grooves 112a, so that the receiving portion 122 abuts the rod 200. For example, the position-limiting member 120 can be configured in an Ω-shape, with a fixing protrusion 121 at each end. The receiving portion 122 connects the two fixing protrusions 121. The mounting portion 112 is provided with two oppositely opened fixing grooves 112a. The two fixing protrusions 121 are correspondingly inserted into the two fixing grooves 112a, thereby securing the position-limiting member 120 to the mounting portion 112. The receiving portion 122 and the mounting portion 112 surround the outer side of the rod 200. It is understood that the receiving portion 122 is provided with the aforementioned first curved surface.

[0037] See again Figure 2 and Figure 3 In some embodiments, the locking assembly 130 further includes a pressure member 133 located between the adjusting member 131 and the locking member 132. The adjusting member 131 presses the locking member 132 via the pressure member 133. The elastic modulus of the pressure member 133 is greater than that of the locking member 132. In other words, the rigidity of the pressure member 133 is greater than that of the locking member 132. This arrangement prevents the pressure member 133 from deforming when subjected to the force of the adjusting member 131.

[0038] The pressure-bearing member 133 can be configured as a plate or block to increase the contact area between the pressure-bearing member 133 and the locking member 132 . This can prevent the pressure-bearing member 133 from exerting excessive pressure on the locking member 132 , thereby preventing the locking member 132 from being damaged.

[0039] See again Figure 2 and Figure 3 In some embodiments, the adjustment member 131 includes a knob 131a and a screw 131b. The mounting portion 112 is provided with a screw hole (not shown). The knob 131a is disposed between the grip portion 111 and the mounting portion 112. The end of the screw 131b facing the grip portion 111 is fixedly connected to the knob 131a. The end of the screw 131b away from the grip portion 111 passes through the screw hole and presses the pressure member 133. The screw 131b and the screw hole are engaged by threads. Thus, by rotating the knob 131a, the screw 131b moves away from the grip portion 111, and the screw 131b pushes the locking member 132 toward the limiting member 120, thereby enabling the locking member 132 and the limiting member 120 to cooperate to clamp the rod 200. In some other solutions, when the pressure-bearing member 133 is not provided in the locking assembly 130 , the screw rod 131 b may also directly press the locking member 132 .

[0040] See also Figure 3 In some embodiments, the pressure member 133 has an annular protrusion 133a on the side facing the screw 131b to form a positioning groove 133b. The end of the screw 131b away from the knob 131a extends into the positioning groove 133b. The positioning groove 133b can be used to position the end of the screw 131b, making the force application point of the screw 131b more reasonable and preventing the screw 131b from bending or deforming.

[0041] Alternatively, in a specific setting, the end face of the screw 131b may be in contact with the bottom surface of the positioning groove 133b to achieve abutment between the screw 131b and the pressure-bearing member 133; or, an annular protrusion (not shown) may be provided in the middle portion of the screw 131b, the outer diameter of the protrusion being larger than the outer diameter of the rest of the screw 131b to form a step surface, so that the step surface contacts the surface of the annular protrusion facing the knob 131a; or, the screw 131b includes It includes a first section 131c and a second section 131d that are coaxially arranged, one end of the first section 131c is fixedly connected to the knob 131a, the other end of the first section 131c is fixedly connected to one end of the second section 131d, the other end of the second section 131d abuts the bottom of the positioning groove 133b, and the outer diameter of the second section 131d is smaller than the outer diameter of the first section 131c, so as to form an abutment surface at the connection between the first section 131c and the second section 131d, and the abutment surface abuts the annular protrusion 133a.

[0042] In some embodiments, a receiving groove 112b is provided on a side of the mounting portion 112 facing away from the gripping portion 111, and the locking member 132 is located in the receiving groove 112b. This arrangement can reduce the volume of the auxiliary handle 100.

[0043] In some embodiments, the profile of the receiving groove 112b complements the outer profile of the locking member 132, and the inner wall of the receiving groove 112b is used to prevent the locking member 132 from rotating relative to the mounting portion 112. Alternatively, the profile of the receiving groove 112b can be non-circular, such as a polygon or an ellipse, and the outer profile of the locking member 132 can match the profile of the receiving groove 112b and also be non-circular. Alternatively, the profile of the receiving groove 112b can be circular, with a positioning protrusion or a positioning groove provided on the inner wall of the receiving groove 112b. The outer profile of the locking member 132 can also be circular, and a groove or a protrusion can be provided on the outer wall of the locking member 132 to mate with the positioning protrusion or the positioning groove. In this way, when the locking member 132 is assembled into the receiving groove 112b, the locking member 132 cannot rotate relative to the mounting portion 112, thereby preventing the locking member 132 from twisting relative to the rod 200 and being damaged.

[0044] It should be noted that, in this embodiment, the above-mentioned various solutions can be arbitrarily combined according to actual needs if there is no conflict between them.

[0045] This embodiment also provides a garden tool (not shown), including: a main body (not shown), a cutting device (not shown), a rod 200 fixedly connecting the main body and the cutting device, and any of the above-mentioned auxiliary handles 100, the main body and the cutting device are respectively arranged at opposite ends of the rod 200, and the auxiliary handle 100 is movably arranged on the rod 200.

[0046] In some embodiments, the gardening tool may be a long-pole electric tool, such as a lawn mower, a high-branch saw, and the like.

[0047] The auxiliary handle and garden tool provided by the embodiments of the present invention are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above implementation methods is only used to help understand the concept of the present invention. There may be changes in the specific implementation methods and application scope. In summary, the contents of this specification should not be understood as limiting the present invention.
