Description

Technical Field

[0001] This utility model relates to the field of electric chainsaw technology, and more specifically, to a split-type electric chainsaw. Background Technology

[0002] An electric chainsaw is a woodworking power tool used in gardening that uses a rotating chain saw blade for sawing. When in use, a power cord is connected to the handle, which then starts the chainsaw on the machine head to cut. A typical electric chainsaw includes a power supply assembly, a housing assembly, a drive assembly, a transmission assembly, a saw blade, and a button. The power supply assembly includes a lithium battery pack and an electronic control board. When the button is pressed, the lithium battery pack powers the drive assembly, which in turn drives the saw blade through the transmission assembly to complete the cutting operation.

[0003] However, existing small handheld electric chainsaws can only be used by hand and cannot handle the trimming of branches and shrubs at higher positions, thus limiting their applicability.

[0004] Therefore, a solution needs to be proposed to address this problem. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a split-type electric chainsaw. By setting up a detachable gripping housing and an extension housing, and adding an extension accessory between the two, the operating height of the chainsaw can be adjusted according to needs to meet the usage requirements in more situations.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a split-type electric chainsaw, including a housing, the housing including a gripping housing and an extension housing detachably disposed from the gripping housing, the chainsaw being installed at the end of the extension housing away from the gripping housing, a battery compartment being disposed inside the gripping housing, an electrical contact being disposed at the end of the gripping housing near the extension housing, a socket for inserting and conducting electricity being disposed on the side wall of the extension housing, two symmetrically distributed locking blocks being fixedly connected to the end of the extension housing near the gripping housing, a slot being provided on the side wall of the gripping housing for the locking blocks to be inserted, a fastening hole being provided on both sides of the inner wall of the slot being provided, and a fastening hole being provided on both sides of the locking blocks being provided, after the locking block is inserted into the slot being positioned, the fastening hole being positioned and the fastening hole being positioned, and a screw being tightened in the corresponding fastening hole being positioned, and a detachable extension accessory being provided between the gripping housing and the extension housing.

[0007] By adopting the above technical solution, a wiring port for connecting to an external power source is provided on the side wall of the gripping housing. A handle is fixedly installed on the outer wall of both the gripping housing and the extension housing. A switch button is provided on the gripping housing, and an electronic control board electrically connected to the battery pack is located inside. When the extension housing and gripping housing are normally connected, a locking block 1 on the extension housing inserts into a locking slot 1 on the gripping housing. Screws are tightened into fastening holes 1 and 2, preventing the locking block 1 from being pulled out of the slot 1, thus connecting the extension housing and gripping housing. When the extension housing and gripping housing are connected, electrical contacts are inserted into a socket for conduction, allowing the chainsaw to operate normally. When it is necessary to prune branches at higher elevations, the screws in fastening holes 1 and 2 are unscrewed. Without the screws limiting the movement, the locking block 1 can be pulled out of the slot 1, separating the gripping housing and the extension housing. An extension accessory is then installed between them to extend the chainsaw, allowing it to prune branches at higher elevations, meeting the needs of various usage scenarios.

[0008] The present invention is further configured such that: the extension accessory includes a mounting base one and a mounting base two, the mounting base one is detachably connected to the gripping housing, the mounting base two is detachably connected to the extension housing, and an extension rod is fixedly connected between the mounting base one and the mounting base two.
