[0024] The following will be combined with the accompanying drawings in the embodiment of the present invention to clearly and completely describe the technical solutions in the embodiment of the present invention. Figure 2 In the figure, the direction of the host body 1 relative to the connecting rod 2 is defined as "downward".

[0025] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4The utility model provides a technical solution: a multifunctional garden pruning device with a replaceable main body head, comprising a main body 1, a connecting rod 2, a connecting head 3 and a main body head 4. The main body 1 is connected to one end of the connecting rod 2, and the other end of the connecting rod 2 is connected to the connecting head 3 through a connecting assembly 5. The connecting assembly 5 includes a first connecting portion 51 detachably connected to the connecting rod 2, a second connecting portion 52 connected to the connecting head 3, a first connecting member 53 for connecting the first connecting portion 51 and the connecting rod 2, and a second connecting member 54 for connecting the second connecting portion 52 to the connecting head 3. The first connecting portion 51 can rotate along the axial direction of the connecting rod 2 and is positioned by the first connecting member 53, the second connecting portion 52 cooperates with the connecting head 3 and the connecting head 3 can swing relative to the second connecting portion 52 and is positioned by the second connecting member 54, and the swing axis of the connecting head 3 is perpendicular to the axis of the connecting rod 2.

[0026] In this embodiment, a multifunctional garden pruning device with a replaceable main unit head only requires a main unit body 1 and a connecting rod 2. Different main unit heads 4 can be used in conjunction with different tasks. In addition, a connecting assembly 5 is provided between the connecting head 3 and the connecting rod 2, and the first connecting portion 51 of the connecting assembly 5 is matched with the first connecting member 53 to drive the connecting head 3 to rotate along the axial direction of the connecting rod 2. At the same time, the second connecting portion 52 of the connecting assembly 5 is matched with the second connecting member 54 to drive the connecting head 3 to swing up and down relative to the connecting assembly 5 to adjust to a suitable angle for garden pruning. This solves the technical problem in the prior art that different machines need to be used in garden pruning, resulting in the gardener having to carry a large number of different types of tools to cooperate with garden pruning, which in turn makes the garden pruning work cumbersome and complicated and inconvenient to carry.

[0027] It should also be noted that the connector 3 is provided with a motor capable of driving the host head 4, and the host body 1 is provided with a power supply, which is connected to the motor in the connector 3 via a wire passing through a connecting rod to provide power to the motor. Detailed description is omitted here.

[0028] Furthermore, the first connecting portion 51 is a cylindrical structure with one end (lower end) open, and the cylindrical structure is used to plug the connecting rod 2 to facilitate the connection of the connecting rod 2.

[0029] Furthermore, the first connector 53 includes four insertion slots 531 spaced apart on the connecting rod 2. Connecting slots are provided on the cylindrical structure in opposite directions, and the connecting slots engage with the corresponding insertion slots 531 to secure the connecting rod 2. The first connector 53 also includes a locating pin 532, which sequentially passes through the connecting slot on one side, the corresponding two insertion slots 531, and finally exits the connecting slot on the other side for positioning. Specifically, when the first connector 51, connector 4, and main unit head 4 are rotated 90° along the axis of the connecting rod 2 to accommodate different main unit heads 4, the connection is more stable.

[0030] Furthermore, the second connecting portion 52 is a transverse sleeve perpendicular to the cylindrical structural member, and the transverse sleeve is matched and connected with the connecting head 3 .

[0031] Furthermore, the connector 3 has two corresponding connecting ears 31. One connecting ear 31 has a positioning post 32 formed inwardly, and one end of the transverse sleeve is sleeved on the positioning post 32. The other connecting ear 31 has a sliding hole 33. The inner side of the sliding hole 33 is circumferentially formed with a plurality of first positioning teeth 34. This facilitates the stable connection between the connector 3 and the second connecting portion 52.

[0032] Furthermore, the second connector 54 includes a plurality of second positioning teeth 541 spaced circumferentially along the inner wall of the transverse sleeve, a return spring 542 disposed within the transverse sleeve, and a push-button 543 capable of being inserted relative to the transverse sleeve. The push-button 543 can be installed in the second positioning teeth 541 of the transverse sleeve through the first positioning teeth 34 in the sliding hole 33. The return spring 542 is disposed between the push-button 543 and the positioning post 32. A plurality of positioning teeth 544 are disposed on the outer wall of the push-button 543 near the transverse sleeve, which cooperate with the first positioning teeth 34 and the second positioning teeth 541. When the connector 3 oscillates axially relative to the transverse sleeve, pressing the push-button 543 causes the push-button 543 to move toward the transverse sleeve, thereby releasing the engagement between the positioning teeth 544 and the first positioning teeth 34 and fully extending into the second positioning teeth 541, thereby completing the rotation of the connector 3 relative to the second connecting portion 52. In this embodiment, the locking interface is simple, easy to operate, and easy to achieve the up and down swinging of the connector 3 relative to the second connecting portion 52 , which has strong operability and better matches the use of different host heads 4 .

[0033] Furthermore, a motor is provided in the connector 3 to drive the main unit head 4, and the connector 3 and the main unit head 4 are fixed by a card slot and a card block, which facilitates the installation and removal of the main unit head 4 and is easy to store and use.

[0034] Furthermore, the main unit head 4 is any one of an electric chain saw, a grass trimmer, and a windbreaker. Of course, it is not limited to the above main unit heads 4, and they are not listed one by one here.
