As shown in fig. 1, the proximal holding member 400 and the distal holding member 500 define a central axis B, i.e., a line connecting the centers of the two. The shell body 100, the electricity placing part 200, the proximal holding member 400, the distal holding member 500 and the like are symmetrically arranged on two sides of the central axis B, so that the center of gravity of the device is prevented from shifting to influence the operation experience. For example, the number of the electricity applying parts 200 is two, and the two electricity applying parts 200 are symmetrically disposed on both sides of the central axis B.

Further, the included angle a may be referred to as an included angle range between the visible end surface 1001 and the central axis B. And a dimension of the proximal grip 400 in the medial axis that is greater than or equal to 1.5 times a dimension of the visible end face 1001 in the medial axis to define a distance between the user and the visible end face 1001 for holding the proximal grip 400 and the distal grip 500.

In addition, the viewing end 1001 may have a display area, in which the power receiving portion 200 is exposed, the display area being disposed obliquely with respect to the distal holding member 500 toward the proximal holding member 400. And the included angle a can be seen in the range of the included angle between the display area and the central axis B. It can be seen that the other regions of the visible end surface 1001 may be horizontally disposed except for the display region which is obliquely disposed. As shown in fig. 1, 2 and 4, the power tool further includes an ejection assembly 800, the ejection assembly 800 includes an ejection trigger 810 and at least one ejection driving member 820, the ejection trigger 810 is disposed on the visible end surface 1001, and the ejection driving member 820 is disposed in the power placing portion 200 and is drivingly connected to the ejection trigger 810.

That is, when the user presses the ejection trigger 810, the battery held in the power receiving unit 200 is ejected, so that the batteries can be plugged and unplugged simultaneously, and the efficiency is effectively improved. Specifically, the battery is used to cooperate with a terminal 220 to realize conduction between the battery and the driving control assembly 300, the terminal 220 is disposed at the bottom of the power installation portion 200, the battery has an interface cooperating with the terminal 220, when the battery 900 is inserted into the power installation portion 200 and the interface cooperates with the terminal 220, the battery is conducted with the driving control assembly 300, and when the ejection trigger 810 is pressed by a user, the battery 900 is ejected from the power installation portion 200 by the ejection driving member 820, and the interface of the battery is separated from the terminal 220, that is, the power supply of the battery 900 to the driving control assembly 400 is blocked.

It should be noted that, when the number of the power receiving portions 200 and the number of the batteries are two, the bottom of each power receiving portion 200 is provided with one of the ejection driving members 820, and at this time, the two ejection driving members 820 are simultaneously controlled by one of the ejection triggering members 810, and the two batteries are simultaneously inserted and pulled out, so that the operation is simpler and more convenient.

The ejection assembly 800 further includes a link, a spring, etc., and the link is connected between the ejection trigger 810 and the ejection driving member 820 to realize the linkage of the two. The spring is installed on the ejection trigger 810 and the ejection driving member 820 so as to be reset by a spring force, and taking the ejection trigger 810 as an example, when the ejection trigger 810 is pressed by a user, the ejection trigger 810 drives the ejection driving member 820 against the spring force, and when the external force is released, the ejection trigger 810 is reset by the reset force of the spring.

As shown in fig. 1 and 2, the ejection trigger 810 is located on the visible end surface 1001 and between the power placing portion 200 and the proximal holding member 400.

Since the pop-up trigger 810 is located on the visual end surface 1001, and the visual end surface 1001 is located in the visual field of the tool held by the operator, the pop-up trigger 810 is convenient to be pressed down by one hand of the operator to insert and extract the battery.

The user is required to press the two switches 410 at the same time to drive the driving control assembly 300 to operate, so that the driving control assembly can be stably held, and safety accidents caused by the fact that the operator only holds one hand are prevented.

As shown in fig. 1, the power tool further includes a cutter member 600, the cutter member 600 being mounted to the operative end surface 1002 and drivingly connected to the drive control member 300. That is, the cutter assembly 600 is driven by the drive control assembly 300 to perform cutting.

Referring to fig. 1, the cutter member 600 and the electrifying part 200 are held on the same side with respect to the drive control member 300. That is, the cutter assembly 600 and the distal grip 500 are held on the same side with respect to the housing main body 100, so that the user can cut with the cutter assembly 600 located at the distal end of the user while holding the proximal grip 400 and the distal grip 500 by hand.

With continued reference to fig. 1 and 2, the cutter assemblies 600 are symmetrically disposed on either side of the central axis B. And the cutter member 600 is held in a parallel orientation to the centre axis B, i.e. the angle between the visible end surface 1001 and the cutter member 600, see angle a.

As shown in fig. 1, the drive control assembly 300 includes a power member 310 and a transmission member 320, the transmission member 320 being drivingly connected between the power member 310 and the cutter assembly 600. The power member 310 may be a motor, which is maintained in a vertical direction of the central axis B. The transmission member 320 may be a gear or a pulley, and the output shaft of the transmission member 320 is inserted through the operation end face 1002, so that the cutter assembly 600 is connected to the output shaft of the transmission member 320.

It can be seen that the knife assembly 600 is removably mounted to the operative end face 1002 to allow for replacement and removal of the knife assembly 600. The cutter assembly 300 is replaced according to different cutting objects, so that the electric cutting tool forms a pruner, a chain saw and the like, and further the applicability is improved, and the electric cutting tool is popularized and applied.

As shown in fig. 1 and 3, the electric power tool further includes a cover 700, and the cover 700 is mounted on the operation end surface 1002 such that a connection position of the cutter member 600 and the drive control member 300 is accommodated between the cover 700 and the housing main body 100.

The driving control assembly 300 further includes a control board 330, wherein the control board 330 is disposed between the power member 310 and the power receiving portion 200, and is electrically connected to the power member 310.
