[0013] In summary, the technical effects and advantages of the utility model are:

[0014] 1. The utility model benefits from the setting of the battery fixing block, which can be screwed into the power tool body for quick installation and positioning. Then, by screwing the adjusting bolt, the movable disk is driven through the connecting rod to drive the fixing column to extend out of the upper and lower sides of the battery fixing block to be fixed with the corresponding jacks on the upper and lower sides of the power tool body. Conversely, the battery fixing block can be removed from the power tool body. The overall disassembly and assembly is simple, which is conducive to the disassembly and assembly of the battery pack fixing frame and the battery body. It is easy to use and is suitable for use in occasions where the battery pack needs to be replaced frequently, which is conducive to improving work efficiency.

[0015] 2. Thanks to the arrangement of the adjusting bolt and the spring, the utility model not only utilizes the threaded installation of the adjusting bolt in the buckle groove to press the movable disk against the inner wall of the telescopic groove to ensure that the connecting rod drives the fixing column to extend out of the battery fixing block for fixing, but also the spring will always push the movable disk toward the inner wall of the telescopic groove to avoid the problem that the threaded installation of the adjusting bolt loosens, causing the fixing column to retract into the telescopic groove and causing the battery fixing block to fall off from the power tool body. Therefore, the stable installation effect of the battery pack during actual use of the power tool can be ensured, which is conducive to improving the normal use of the battery pack.

[0016] 3. Thanks to the arrangement of several counterweight studs on the base body, the utility model can conveniently adjust the weight of the base body by disassembling the counterweight studs, so that the electric tool can meet the handheld load requirements of different users and is flexible to use.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Reference Figure 1 and Figure 2 An electric tool that is easy to disassemble and assemble a battery pack is shown, comprising an electric tool body 1, a power display screen 101 is installed on the upper end surface of the electric tool body 1, a handle 2 is fixed to the bottom of the electric tool body 1, and a control button 201 is installed on the handle 2 to facilitate operation control.

[0026] refer to Figure 2 , Figure 3 and Figure 4 As shown, a battery fixing block 3 is threadedly inserted at one end of the electric tool body 1 away from the electric output end, so that the battery fixing block 3 can be quickly positioned on the electric tool body 1, and a battery pack fixing frame 4 is fixed to the side of the battery fixing block 3 facing the inside of the electric tool body 1, and a plurality of battery bodies 5 are inserted and installed in the battery pack fixing frame 4, and heat dissipation grooves 401 are provided on the upper and lower end faces of the battery pack fixing frame 4, and positive and negative electrode blocks are fixed to the side of the battery pack fixing frame 4 away from the battery fixing block 3, and are electrically connected to the circuit inside the electric tool body 1.

[0027] Specific as Figure 3 and Figure 4 As shown, a buckle groove 301 is provided in the middle of one side of the battery fixing block 3 away from the power tool body 1, an adjusting bolt 6 is provided in the middle of the buckle groove 301, and a telescopic groove 302 is provided in the middle of the battery fixing block 3, and fixing columns 7 are provided at both upper and lower ends of the telescopic groove 302, and two fixing columns 7 extend out of the upper and lower sides of the battery fixing block 3 respectively, and are engaged with the corresponding jacks provided on the upper and lower sides of the power tool body 1, one end of the adjusting bolt 6 is threadedly inserted into the middle of the telescopic groove 302, and a movable disk 601 is rotatably installed, and connecting rods 701 movably connected to the fixing columns 7 are provided on the upper and lower sides of the movable disk 601, so that the adjusting bolt 6 can be fixed by making the movable disk 601 abut against the inner wall of the middle part of the telescopic groove 302, so that the connecting rod 701 drives the fixing column 7 to extend out of the outside of the battery fixing block 3 and engage with the corresponding jacks provided in the power tool body 1.

[0028] In addition, a spring 602 is sleeved on the adjusting bolt 6, one end of the spring 602 abuts against the middle inner wall of the telescopic slot 302, and the other end abuts against the surface of the movable disk 601, and elastically abuts the movable disk 601 in a direction away from the adjusting bolt 6, so that the spring 602 can prevent the adjusting bolt 6 from loosening to a certain extent and drive the spring 602 toward the outside of the battery fixing block 3, thereby causing the fixing column 7 to retract into the telescopic slot 302. Therefore, the setting of the spring 602 can further keep the fixing column 7 extending out of the battery fixing block 3 and fixing it with the corresponding jack in the power tool body 1, thereby avoiding the battery pack from easily falling off due to the convenient disassembly and assembly as mentioned above, and the use effect is good.

[0029] refer to Figure 1 and Figure 5As shown, an electric tool base is suitable for the above-mentioned electric tool that is easy to disassemble and assemble the battery pack, including a base body 8 fixed to the bottom of the handle 2, and a plurality of counterweight studs 801 are installed on the side of the base body 8 through threaded insertion.

[0030] The practical working principle of the present invention is as follows: the electric tool which is easy to disassemble and assemble the battery pack can be screwed into the electric tool body 1 for quick installation and positioning when in use, and then the movable disk 601 is driven to drive the fixing column 7 to extend out of the upper and lower sides of the battery fixing block 3 through the connecting rod 701 by screwing the adjusting bolt 6, so as to engage with the corresponding jacks on the upper and lower sides of the electric tool body 1 to form a fixation; conversely, the battery fixing block 3 can be removed from the electric tool body 1. The overall disassembly and assembly is simple, which is conducive to the disassembly and assembly of the battery pack fixing frame 4 and the battery body 5. It is easy to use and is suitable for use in occasions where the battery pack needs to be replaced frequently, which is conducive to improving work efficiency.

[0031] At the same time, the device can also use the threaded installation of the adjusting bolt 6 in the buckle groove 301 to make the movable disk 601 close to the inner wall of the telescopic groove 302, so as to ensure that the connecting rod 701 drives the fixing column 7 to extend out of the battery fixing block 3 for fixing. At the same time, by setting the spring 602, the movable disk 601 can always be abutted against the inner wall of the telescopic groove 302 to avoid the problem that the threaded installation of the adjusting bolt 6 becomes loose, causing the fixing column 7 to retract into the telescopic groove 302 and causing the battery fixing block 3 to fall off from the power tool body 1. Therefore, the stable installation effect of the battery pack during the actual use of the power tool can be guaranteed, which is conducive to improving the normal use of the battery pack.

[0032] The weight of the base body 8 of the device can be easily adjusted by disassembling the weight studs 801, so that the power tool can meet the handheld load requirements of different users and is flexible to use.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
