[0033] One embodiment of the present invention provides a connecting mechanism for axially connecting a first rod and a second rod, wherein the inner diameter of the first rod is larger than the outer diameter of the second rod, and the second rod is at least partially located inside the first rod. The connecting mechanism comprises: a connecting member axially sleeved and fixed at one end of the first rod, the connecting member having a first coupling portion and an axially extending through hole, the end of the second rod passing through the through hole and extending into the first rod. An anti-slip member located inside the first rod, the anti-slip member being fixedly connected to one end of the second rod, the outer diameter of at least part of the anti-slip member being larger than the inner diameter of at least part of the connecting member, so that the anti-slip member cannot be detached from the first rod, thereby preventing the second rod from detaching from the first rod. And a locking member sleeved on the outer periphery of the second rod, the locking member having a second coupling portion detachably coupled to the first coupling portion, so that the first rod and the second rod are relatively fixed.

[0034] An embodiment of the present invention further provides a gardening tool, comprising: a first rod, a second rod and the above-mentioned connecting mechanism, wherein the first rod and the second rod are detachably coaxially connected via the connecting mechanism.

[0035] The following is a detailed description of the implementation details of the connection mechanism of this embodiment. The following content is only provided for ease of understanding and is not necessary for implementing this solution.

[0036] See also Figure 1 and Figure 2 The connecting mechanism 100 of this embodiment is used to detachably connect a first rod 201 and a second rod 202, thereby adjusting the overall rod length to meet different practical needs. At least the first rod 201 is hollow, allowing a portion of the second rod 202 to extend into the first rod 201. Alternatively, both the first rod 201 and the second rod 202 are hollow, further reducing the overall weight of the rod.

[0037] The connector 110 is at least partially sleeved onto one end of the first rod 201 and may have an axis that coincides with the axis of the first rod 201. The connector 110 includes a first coupling portion and an axially extending through hole 111. One end of the second rod 202 passes through the through hole 111 and extends into the interior of the first rod 201. The connector 110 may be a single-piece component or a modular structure, and may be composed of one or more of metal, metal oxide, and plastic.

[0038] The locking member 120 is sleeved on the outer circumference of the second rod member 202, and the locking member 120 is provided with a second coupling portion that is detachably fixed to the first coupling portion. By quickly matching and locking the first coupling portion and the second coupling portion, the first rod member 201 and the second rod member 202 can be quickly and firmly connected; by decoupling the first coupling portion and the second coupling portion, the first rod member 201 and the second rod member 202 can be quickly disassembled.

[0039] The anti-slip member 130 is fixed to the end of the second rod member 202 and is located inside the first rod member 201. The outer diameter of at least part of the anti-slip member 130 is larger than the inner diameter of at least part of the connecting member 110. The anti-slip member 130 is restricted by the connecting member 110 and cannot be separated from the first rod member 201, so that the second rod member 202 can be firmly and reliably fixed to the first rod member 201.

[0040] It can be understood that due to the limitation of the anti-slip member 130, to completely separate the first rod 201 and the second rod 202, it is only necessary to remove the connecting member 110 from the first rod 201. The connecting member 110 and the locking member 120 can remain engaged, and there is no need for repeated disassembly and assembly, and the disassembly and assembly between the two rods can be completed quickly.

[0041] See also Figure 2 In this embodiment, the connecting member 110 may be provided with a screw hole perpendicular to the first rod 201, and a screw may be screwed into the screw hole, and the screw may be used to press against the first rod 201, thereby fixing the connecting member 110 to the first rod 201. Alternatively, the first rod 201 may be provided with a positioning hole 201a, and the inner wall of the connecting member 110 may be provided with a positioning protrusion 112, which is embedded in the positioning hole, so that the connecting member 110 is clamped and fixed to the first rod 201. Alternatively, an axially extending gap can be further provided on the connecting member 110, and two opposite latching structures extend from both sides of the gap of the connecting member 110 in the radial direction away from the rod, and the latching structures each have a latching hole 113, and the latching hole 113 is used for allowing a bolt 113a to pass through. After the bolt 113a passes through, it is connected and fixed with a nut 113b to fix the connecting member 110 on the first rod 201, wherein a gasket 113c can be provided between the two latching structures, one end of the gasket 113c is inserted into the above-mentioned positioning hole 201a, and the other end has a through hole, and the bolt 113a passes through the latching hole 113 and the through hole in turn and is connected with the nut 113b, and the gasket 113c is used to prevent the bolt 113a and the nut 113b from excessive rotation and damaging the latching structure.

[0042] See also Figures 1 to 3 In one embodiment, the first coupling portion includes a locking groove 114 provided on the connecting member 110, and the second coupling portion includes a protrusion 121 provided on the locking member 120. When the protrusion 121 is configured to fit into the locking groove 114 and engage the inner wall of the locking groove 114, the locking member 120 and the connecting member 110 are relatively fixed. It can be seen that the cooperation between the locking groove 114 and the protrusion 121 can achieve rapid locking, making the assembly and disassembly of the connecting mechanism 100 more convenient.

[0043] Specifically, the locking groove 114 is provided on the outer wall of the connecting member 110. The locking member 120 is a hollow structure with an inner diameter larger than the outer diameter of the second rod 202. The protrusion 121 is provided on the inner wall of the locking member 120. When the first rod 201 and the second rod 202 need to be locked, the protrusion 121 is inserted into the locking groove 114 and the protrusion 121 and the inner wall of the locking groove 114 are engaged with each other, thereby fixing the connecting member 110 and the locking member 120 to each other, and further fixing the first rod 201 and the second rod 202 to each other in the circumferential direction.

[0044] In one embodiment, there are multiple locking grooves 114, and the multiple locking grooves 114 are spaced apart along the circumference of the connecting member 110. There are also multiple protrusions 121, and the protrusions 121 are spaced apart along the circumference of the locking member 120. The multiple protrusions 121 are embedded in the multiple locking grooves 114 in a one-to-one correspondence, so that the locking member 120 and the connecting member 110 are more firmly fixed to each other.

[0045] It is understood that, to control costs and ensure the mechanical strength of the connector 110, the number of each of the locking grooves 114 and the protrusions 121 can be two, with the two locking grooves 114 being provided on opposite sides of the connector 110, and the two protrusions 121 being provided on opposite sides of the locking member 120. In other embodiments, the number and position of the locking grooves 114 and the protrusions 121 can also be adjusted to other numbers according to actual needs.

[0046] See again Figure 2 and Figure 3 In one embodiment, the locking groove 114 includes a first limiting groove 114a extending at an angle to the axial direction of the connecting member 110, and an opening 114b provided at an end of the connecting member 110 near the locking member 120. The opening 114b communicates with the first limiting groove 114a. Thus, when the connecting member 110 and the locking member 120 are fixed to each other, the protrusion 121 enters the first limiting groove 114a through the opening 114b. The locking member 120 is then rotated to move the protrusion 121 relative to the connecting member 110. When the protrusion 121 moves to a position in the first limiting groove 114a away from the opening 114b, the protrusion 121 abuts against or engages the inner wall of the first limiting groove 114a.

[0047] In one embodiment, a first limiting protrusion 114c is provided on the inner wall of the first limiting groove 114a at a position close to the opening 114b. The first limiting protrusion 114c reduces the internal space of the first limiting groove 114a at the corresponding position to reduce the possibility of the protrusion 121 detaching from the connecting member 110 from the opening 114b.

[0048] Optionally, the first limiting protrusion 114c may be wedge-shaped, block-shaped, semi-cylindrical, hemispherical, etc., and may be specifically selected and set according to actual needs.

[0049] In one embodiment, the locking groove 114 further includes a second limiting groove 114d extending axially along the connecting member 110, and a third limiting groove 114e extending at an angle to the axial direction of the connecting member 110. One end of the second limiting groove 114d is connected to the end of the first limiting groove 114a away from the opening 114b, and one end of the second limiting groove 114d is connected to the third limiting groove 114e. This arrangement allows, when necessary, the protrusion 121 entering the first limiting groove 114a to pass through the second limiting groove 114d and into the third limiting groove 114e. Upon rotation of the locking member 120, the protrusion 121 engages with the inner wall of the third limiting groove 114e. After the locking member 120 and the connecting member 110 are secured to each other, the end of the locking member 120 away from the connecting member 110 supports the second rod 202.

[0050] It will be appreciated that the third limiting groove 114e is located on the side of the first limiting groove 114a away from the locking member 120. In other words, by moving the protrusion 121 from the first limiting groove 114a to the third limiting groove 114e, or vice versa, the position at which the locking member 120 supports the second rod 202 and the distance between the locking member 120 and the connecting member 110 can be changed. When the protrusion 121 is located in the third limiting groove 114e, the distance between the locking member 120 supporting the second rod 202 and the connecting member 110 is shorter; when the protrusion 121 is located in the first limiting groove 114e, the distance between the locking member 120 supporting the second rod 202 and the connecting member 110 is longer.

[0051] In one embodiment, a second limiting protrusion 114f is provided on the inner wall where the third limiting groove 114e and the second limiting groove 114d are connected. The second limiting protrusion 114f reduces the internal space of the third limiting groove 114e at the corresponding position to reduce the possibility of the protrusion 121 detaching from the connecting member 110 from this position.

[0052] Optionally, the second limiting protrusion 114f may be wedge-shaped, block-shaped, semi-cylindrical, hemispherical, etc., and may be specifically selected and set according to actual needs.

[0053] See also Figure 1 and Figure 4In one embodiment, the connecting mechanism 100 further includes an elastic member 140 sleeved around the outer periphery of the second rod 202. The elastic member 140 is located within the locking member 120, with one end of the elastic member 140 abutting the locking member 120 and the other end abutting the fastening sleeve 150. The elastic member 140 abuts the connecting member 110 via the fastening sleeve 150. When the connecting member 110 and the locking member 120 are fixed to each other, the elastic member 140 is compressed, and the two ends of the elastic member 140 apply force to the connecting member 110 and the locking member 120, respectively, causing the connecting member 110 and the locking member 120 to move away from each other, thereby causing the protrusion 121 to firmly press against or retain the inner wall of the first limiting groove 114a or the third limiting groove 114e, thereby achieving self-locking of the connecting mechanism 100. The elastic member 140 may be a spring or a metal spring, which is not specifically limited in the present invention.

[0054] See also Figure 5 In one embodiment, the connector 110 includes a first accommodating section 115 and a second accommodating section 116, which are sequentially connected. The first accommodating section 115 is sleeved around the outer circumference of the first rod 201 and is fixedly connected to the first rod 201. The anti-slip member 130 is located in the first accommodating section 115. The inner diameter of the second accommodating section 116 is smaller than the outer diameter of the anti-slip member 130 to prevent the anti-slip member 130 from escaping from the first accommodating section 115.

[0055] See also Figure 6 , and see again Figure 4 The connecting mechanism 100 further includes a securing sleeve 150 disposed around the outer circumference of the second rod 202. The securing sleeve 150 is located within the locking member 120. At the end of the second accommodating section 116 distal from the first accommodating section 115, at least a portion of its inner wall is configured as an inclined surface or a conical surface along the circumference. The securing sleeve 150 includes a wedge-shaped portion 151, which is configured to cooperate with the inclined surface or conical surface to secure the second rod 202. For example, the inner wall of the portion of the second accommodating section 116 distal from the first accommodating section 115 can be configured as a complete conical surface. As the wall thickness of the second accommodating section 116 with the conical surface gradually decreases from the first accommodating section 115 toward the second accommodating section 116, the distance between the conical surface and the outer surface of the second rod 202 gradually increases. The wedge-shaped portion 151 extends into the space enclosed by the conical surface, with one surface forming an interference fit with the conical surface and the other surface contacting the outer surface of the second rod 202, thereby securing the first rod 201 and the second rod 202.

[0056] In this case, the axial dimension of the inclined or conical surface of the second accommodating section 116 can be set to be larger than the axial dimension of the wedge-shaped portion 151, so that the space enclosed by the inclined or conical surface has a certain degree of redundancy relative to the wedge-shaped portion 151. When the second accommodating section 116 undergoes a certain degree of deformation, the wedge-shaped portion 151 can be further extended into the space enclosed by the inclined or conical surface, ensuring that the wedge-shaped portion 151 and the second accommodating section 116 continue to maintain a secure fit.

[0057] It is understood that the orientation of the inclined or tapered surface can be appropriately adjusted so that, as the first accommodating section 115 moves toward the second accommodating section 116, the wall thickness of the second accommodating section 116 with the tapered surface gradually decreases, and the distance between the tapered surface and the outer surface of the second rod 202 gradually decreases. In this case, the wedge-shaped portion 151 is correspondingly configured so that, as the first accommodating section 115 moves toward the second accommodating section 116, the wall thickness of the wedge-shaped portion 151 gradually increases, and the distance between the inner wall of the wedge-shaped portion 151 and the outer surface of the second rod 202 gradually decreases. When the second accommodating section 116 and the wedge-shaped portion 151 are engaged, the portion of the second accommodating section 116 with the inclined or tapered surface extends into the space enclosed by the wedge-shaped portion 151.

[0058] See again Figure 6 In one embodiment, the clamping jacket 150 further includes a first mounting ring 152 and a plurality of wedge-shaped portions 151 fixed to the first mounting ring 152 at intervals along its circumference. The inner wall of the second receiving section 116 is configured as a tapered surface, and the plurality of wedge-shaped portions 151 cooperate with the tapered surface to secure the second rod 202. By configuring the plurality of wedge-shaped portions 151 as spaced-apart structures, the gaps between the plurality of wedge-shaped portions 151 allow the entire assembly to collapse or contract when the second receiving section 116 and the clamping jacket 150 are mated, thereby better fitting the clamping jacket 150 into the second receiving section 116.

[0059] In one embodiment, the connecting mechanism 100 also includes a stop assembly, which includes a first stop portion provided on the connecting member 110 and a second stop portion provided on the second rod member 202. The first stop portion and the second stop portion are used to cooperate with each other to prevent the second rod member 202 from rotating relative to the first rod member 201.

[0060] See also Figure 1 and Figure 7For example, the first anti-rotation feature is an axially extending anti-rotation protrusion 117 provided on the inner wall of the connecting member 110, while the second anti-rotation feature is an axially extending anti-rotation groove 118 provided on the second rod 202. More specifically, the anti-rotation groove 118 is a concave groove on the second rod 202. When the second rod 202 is inserted into the first rod 201, the anti-rotation protrusion 117 on the first rod 201 engages with the anti-rotation groove 118 on the second rod 202. The anti-rotation protrusion 117 abuts against the inner wall of the anti-rotation groove 118, preventing the second rod 202 from rotating relative to the first rod 201. This ensures that other devices installed on the rod remain relatively stable during use.

[0061] See also Figure 8 In this embodiment, the anti-slip member 130 includes a second mounting ring 131 and a plurality of clamping portions 132. The plurality of clamping portions 132 are fixed to the second mounting ring 131 at intervals along the circumference of the second mounting ring 131. The plurality of clamping portions 132 are provided on the outer circumference of the second rod 202 and are used to secure the anti-slip member 130 to the second rod 202. For example, two clamping portions 132 may be provided and disposed opposite each other, with the two clamping portions 132 clamping and securing the second rod 202 on both sides.

[0062] Furthermore, the anti-slip component 130 also includes a first fixing portion 133, and at least one of the multiple clamping portions 132 is provided with the first fixing portion 133, and a second fixing portion 134 is provided on the second rod 202. The second fixing portion 134 and the first fixing portion 133 cooperate with each other to prevent the anti-slip component 130 from moving axially relative to the second rod 202, that is, to prevent the anti-slip component 130 from detaching from the second rod 202.

[0063] In one embodiment, the first fixing portion 133 is a protrusion provided on the inner wall of the clamping portion 132, and the second fixing portion 134 is a through hole or groove provided on the second rod 202, and the protrusion can be embedded in the through hole or groove to be clamped and fixed on the second rod 202.

[0064] In another embodiment, the protrusion may be provided on the second rod 202 , and the through hole or the groove may be provided on the clamping portion 132 .

[0065] It should be noted that the above-mentioned multiple different implementation methods can be set independently or combined arbitrarily as needed without conflict, and will not be described in detail here.
