Technical Field

The present application relates to the field of power tools, and more particularly, to a cordless power tool with an accessory removal wrench.

Background

With the rapid development of technology and the increasing demand of people for electric tools, cordless electric tools are becoming the mainstream of development. The application range of the cordless electric tool is limited by the lengths of the socket and the power wire, and the cordless electric tool adopts a battery pack for power supply and can be carried about. Meanwhile, electric tool accessories are consumable items, and the accessories are generally installed and replaced by a wrench. In general, the wrench is slightly locked to a certain position of the electric power tool with interference, and is easily separated from the storage position and lost due to various reasons during the use of the electric power tool.

Accordingly, there is a need for improvement to overcome the technical problems in the prior art.

Further, the wrench which is arranged in the wrench accommodating groove is pressed at the second position and directly or indirectly conducts the power supply circuit of the electric tool.

Further, the electric tool is provided with a plugging plane for matching the battery pack, and the mounting opening is arranged in the plugging plane.

Further, when the mounting opening is opened, the wrench receiving slot has an elastic device for pushing the wrench out of the mounting opening for facilitating gripping.

Further, electric tool is the annular saw that has the saw blade and cutting base plate, the spanner accepting groove be lengthwise slot and with the cutting base plate is not less than 20 degrees and is not more than 45 degrees positive contained angles.

Further, the elongated slot is parallel to the circular saw blade.

Furthermore, the electric tool is provided with a plugging plane for matching the battery pack, and the battery pack drives a linkage device to open or block the installation opening when being assembled and disassembled on the plugging plane.

Further, the wrench accommodating groove is disposed on the electric tool body.

Further, the electric tool is an angle grinder, a reciprocating saw or an electric drill.

This application utilizes removable battery package to change for electric tool's the position of installing and removing, need not extra part can be right the installation opening is opened and the separation, has realized reliably accomodating.

Drawings

The present application will be more fully understood by reference to the following detailed description of specific embodiments in conjunction with the accompanying drawings. Wherein:

FIG. 1 is a side view of the power tool body, wrench and battery pack of the present application shown separated;

fig. 2 is a schematic perspective view illustrating a structure of the battery pack of the present application, which is not assembled to the power tool body.

Detailed Description

The following describes in detail a specific embodiment of the power tool of the present application with reference to the drawings.

Referring to fig. 1 to 2, the electric tool of the present application includes an electric tool body 10, a wrench 20 for mounting and dismounting an accessory of the electric tool, a wrench receiving slot 101 for receiving the wrench 20, and a battery pack 30 detachably assembled to the electric tool body 10, wherein the wrench receiving slot 101 has a mounting opening 1011, the battery pack 30 has a first position for directly or indirectly opening the mounting opening 1011 to allow the wrench 20 to be mounted therein, and a second position for directly or indirectly blocking the mounting opening 1011 to prevent the wrench 20 from being detached. This application utilizes removable battery package to change for electric tool's the position of installing and removing, need not extra part can be right installing opening 1011 is opened and the separation, has realized reliably accomodating. In this embodiment, the second position is a working position of the battery pack, and the mounting opening 1011 at this time is blocked, so that the wrench 20 can be better prevented from being disengaged due to vibration; while the first position may be any position other than the working position, such as where the battery pack 30 is fully or partially disengaged from the power tool. Yet another benefit of this design is that the user must first remove the battery pack 30, i.e., cut off power to the power tool, if the user wants to use the wrench 20, which objectively reduces the potential safety risk associated with a live replacement accessory.

The wrench 20 inserted into the wrench receiving slot 101 is pressed at the second position to directly or indirectly conduct the power supply circuit (not shown) of the power tool. The design is ingenious in that the possibility that the wrench 20 is lost is greatly reduced and even eliminated on the basis of ensuring safety. Since the power supply circuit is not turned on because the wrench 20 is not pressed even though the battery pack 30 is returned to the working position as long as the wrench 20 is not inserted into the wrench receiving groove 101, the user is reminded to retrieve the wrench 20 at the first time. In this embodiment, the electric tool has a plugging plane 102 for the battery pack 30 to be matched with, the mounting opening 1011 is disposed in the plugging plane 102, and the battery pack 30 directly participates in blocking the mounting opening 1011 after being mounted. When the battery pack 30 is removed and the mounting opening 1011 is opened, the wrench receiving groove 101 has an elastic means (not shown) for pushing the wrench 20 out of the mounting opening 1011 for grasping. Because spanner accepting groove 101 itself is just narrower, add the needs that this application was covered, spanner 20 is further sunken, sets up an elastic device who pushes out spanner 20, is favorable to reaching this application separation function in, promotes user's operation and experiences.

Referring to the drawings, in the present embodiment, the electric tool is a circular saw having a circular saw blade 40 and a cutting base plate 50, and the wrench receiving slot 101 is a longitudinal slot (the wrench is generally L-shaped, and the long side matches the longitudinal slot) and forms a positive angle with the cutting base plate 50 of not less than 20 degrees and not more than 45 degrees. Since the cutting base plate 50 is in a horizontal state under most conditions of use, the included angle may make the wrench 20 tend to be normally accommodated in the wrench accommodating groove 101, and is more favorable for matching with the battery pack 30. The longitudinal insertion groove is parallel to the circular saw blade 40, so that the wrench receiving groove 101 is formed and formed in the power tool body 10.

The above detailed description is merely illustrative of the present application and is not intended to be limiting. For example, the power tool in this embodiment is a circular saw; in other embodiments, the power tool may also be an angle grinder, a reciprocating saw, or a power drill, as long as there is an accompanying wrench for disassembly. In addition, the battery pack in this embodiment directly participates in blocking the installation opening by using its own surface, but in other embodiments, the battery pack may be configured to indirectly drive a linkage device to open or block the installation opening when being mounted on or dismounted from the plugging plane, so that the object of the present application may also be achieved. In addition, the wrench receiving slot in this embodiment is used to completely receive the wrench, and in other embodiments, the wrench receiving slot may also partially receive the wrench as long as the receiving of the wrench is satisfied. In summary, those skilled in the art can make various changes and modifications without departing from the scope of the present application, and therefore all equivalent technical solutions also belong to the scope of the present application, and the protection scope of the present application should be defined by the claims.
