Problems solved by technology

When the telescopic rod has been repeatedly operated, especially the rotating part, it will be deformed or invalid after repeated operations. When some parts need to be replaced, the outer tube or inner tube integrally formed with it will also need to be replaced together, thus causing resources. waste; in addition, the existing connecting components also have the problem of complex assembly

Embodiment 1

[0031] Such as Figure 1 to Figure 6 As shown, this embodiment is a power tool with a telescopic rod, such as pruning shears, lawn trimmers, snow blowers, etc., including a telescopic rod, one end of the telescopic rod is connected to a hand-held handle, and the other end is equipped with a working head. Handle and working head in Figures 1 to 6 Not shown in the figure, the telescopic rod includes an inner tube 1 and an outer tube 6 sleeved outside the inner tube 1, a connecting tube 3 and a tightening nut 2 are arranged between the inner tube 1 and the outer tube 6, and the connecting tube 3 One end is fixed axially with the outer tube 6, and the connecting tube 3 is clamped when the tightening nut 2 is tightened, and the connecting tube 3 clamps the inner tube 1 at the same time, so that the inner tube 1 and the outer tube 6 are relatively fixed in the axial direction, This is a commonly used telescopic clamping structure for traditional telescopic rods, without further el...

Abstract

The invention discloses an electric tool with a telescopic rod and belongs to the field of electric tools. The electric tool comprises the telescopic rod, and the telescopic rod comprises an inner pipe and an outer pipe arranged outside the inner pipe in a sleeving mode. A connecting pipe and a tightening nut are arranged between the inner pipe and the outer pipe, and a pushing switch is movably mounted on the connecting pipe. A locking sleeve is detachably connected to the outer pipe, and the locking sleeve and the connecting pipe are relatively fixed in the axial direction and can relativelyrotate in the circumferential direction. The locking sleeve is provided with a locking groove allowing the pushing switch to insert, and the pushing switch is inserted into the locking groove, so that the locking sleeve and the connecting pipe are relatively fixed in the circumferential direction. The electric tool has the advantage that it is more convenient for a user to repair the telescopic rod of the electric tool.

Description

【Technical field】 [0001] The invention relates to an electric tool with a telescopic rod, which belongs to the field of electric tools. 【Background technique】 [0002] At present, some electric garden tools, such as lawn trimmers and high-branch saws, are generally provided with telescopic rods in order to adapt to different work requirements and users of different heights, including outer tubes and inner tubes, and between the outer tubes and inner tubes. It can be stretched in the axial direction and locked by locking parts. Since many garden tools have different working environments during actual work, there are corresponding settings on the telescopic rods so that the relative rotation between the inner tube and the outer tube can be adjusted. And the function of locking, after such a design, both the telescopic function and the rotation function can be realized between the outer tube and the inner tube. [0003] In the traditional telescopic rod, some parts of the tele...
