[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and are not used to limit the utility model.

[0029] Example 1

[0030] See also Figure 1-3 The technical solution of a battery pack protection structure suitable for a handheld power tool provided in this embodiment includes the following:

[0031] A first fixing member 1 is provided at the bottom of the front side and the bottom of the back side of the handle 31 of the electric tool;

[0032] The protective member 2 comprises a second fixing member 21 respectively connected to the two first fixing members 1, a first protective member 22 respectively connected to the two second fixing members 21, and a second protective member 23 respectively connected to the two first protective members 22, and the ends of the two second protective members 23 not connected to the first protective members 22 are connected via a first connecting member 24;

[0033] The area enclosed by the first protective member 22 , the second protective member 23 and the lower bottom surface of the handle 31 forms a battery pack protection area 25 .

[0034] Preferably, the protective member 2 is formed by bending a cylindrical tube, and its material is not limited to steel, and may also be other materials such as aluminum and copper.

[0035] In a specific implementation, in order to facilitate the removal and replacement of the battery, the protective member 2 and the power tool are designed to be detachably connected, and the first fixing member 1 is designed to be a claw structure. The size of the clamping interval in the first fixing member 1 matches that of the second fixing member 21. The second fixing member 21 is clamped in the clamping interval. At this time, the claw structure produces a slight elastic deformation. In a specific implementation, the size of the clamping interval can also be designed to be slightly smaller than the outer diameter of the second fixing member 21 to increase the clamping force of the claw structure under elastic deformation.

[0036] In a specific implementation, the overall structural bending style of the protective member 2 matches the shape of the battery pack 33, and the second fixing member 21 is arranged parallel to the front side of the handle 31; the end of the second fixing member 21 away from the power tool body 32 is bent toward the direction away from the bottom of the handle 31 to form the first protective member 22; the end of the first protective member 22 not connected to the second fixing member 21 is bent toward the power tool body 32 to form the second protective member 23.

[0037] Preferably, when the width of the battery pack 33 is greater than the width of the bottom surface of the handle 31, the end of the second fixing member 21 away from the power tool body 32 can be slightly folded to both sides so that the lower bottom surface of the protective member 2 matches the battery pack 33. The present design does not limit the contact position between the second protective member 23 and the bottom of the battery pack 33, and any contact position is within the protection range of the present design.

[0038] Furthermore, the protective member 2 is an integrated structure design, the second fixing member 21 and the first protective member 22 are connected with a rounded transition, the first protective member 22 and the second protective member 23 are connected with a rounded transition, and the second protective member 23 and the first connecting member 24 are connected with a rounded transition.

[0039] Preferably, because the protective member 2 itself is a columnar structure, in order to increase the clamping force, a tooth structure 11 is provided on the inner wall of the claw of the first fixing member 1. Taking a plurality of boss-style tooth structures 11 as an example, the tooth structure 11 provides multiple contact points between the first fixing member 1 and the second fixing member 21. The multi-point contact can increase the friction between the first fixing member 1 and the second fixing member 21, making the connection between the two more stable and reducing the possibility of the second fixing member 21 sliding when subjected to force.

[0040] Preferably, the utility model also designs a reinforcement structure at the end of the second fixing member 21, and in detail, the end of the second fixing member 21 that is not connected to the first protective member 22 is bent toward the front direction of the handle 31 to form a first reinforcement member 26, and a cylindrical circular hole is provided at a position corresponding to the first reinforcement member 26 on the front of the handle 31, and the cylindrical circular hole is the second reinforcement member, and the first reinforcement member 26 matches the second reinforcement member, and the length of the first reinforcement member 26 is longer than the distance from the second fixing member 21 to the front of the handle 31.

[0041] In a specific implementation, the installed structure is: the end of the first reinforcement 26 is clamped in the second reinforcement, the second fixing member 21 is clamped in the first fixing member 1, and the battery pack 33 is accommodated in the battery pack protection area 25 of the protective member 2 and is detachably connected to the power tool body 32; when the battery pack 33 needs to be removed, force is applied to the two second fixing members 21 in the direction away from the front and back of the handle 31, so that the first reinforcement 26 can be separated from the second reinforcement, and the first fixing member 1 can be separated from the second fixing member 21 at the same time, so as to achieve disassembly.

[0042] Example 2

[0043] The present invention further provides a handheld electric tool, comprising an electric tool body 32, a handle 31, a battery pack protection structure as described in Embodiment 1, and a battery pack 33;

[0044] The handle 31 is fixedly connected to the side wall of the power tool, the battery pack protection structure is connected to the handle 31, and the battery pack 33 is disposed in the battery pack protection section 25 of the battery pack protection structure and is detachably connected to the power tool body 32.

[0045] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
