DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1 - Figure 3 In this embodiment, in order to enable the power tool body 1 to be plugged into the battery pack charging seat body 4 through the connecting mechanism 5, the connecting base 3 and the battery pack charging seat body 4 are further limitedly connected and fixed together to ensure that the battery pack charging seat body 4 will not fall and be damaged when the power tool body 1 is in use, and the specific use principle of the connecting mechanism 5 in conjunction with the battery pack charging seat body 4 is as follows:

[0020] Manually pinch the symmetrical slide bar 19 protruding on the right side of the movable plate 11, and the slide bar 19 will slide in the slide opening 14 opened on the right side wall of the movable plate 11, and drive the symmetrical movable rod 17 to make a relative movement operation through the second connecting hole 18 opened on the side wall along the second fixed rod 15 in the movable opening 13 opened on the top surface of the movable plate 11, and force the second compression spring 16 set on the outside of the second fixed rod 15 and installed between the symmetrical movable rods 17 to make a retraction operation from both ends to the center. Then, the hand pinching the symmetrical slide bar 19 keeps the pinching force unchanged and applies pressure downward on the movable plate 11. At this time, the movable plate 11 will pass through the first connecting holes 12 opened on both sides of the top surface along the two sets of installed on the right side of the battery pack charging seat body 4. The first fixing rod 9 installed between the upper and lower symmetrical fixing blocks 8 slides downward, and the movable plate 11 will force the first compression spring 10 on the outer sleeve of the first fixing rod 9 to retract during the process of sliding downward along the first fixing rod 9 through the first connecting hole 12, until the height position of the symmetrical movable rod 17 protruding from the top surface of the movable plate 11 does not exceed the height of the battery pack charging seat body 4, and will not cause any obstruction to the plug-in operation of the power tool body 1. Then, the power tool body 1 is installed from right to left on the battery pack charging seat body 4 through the connecting base 3 installed at the bottom end of the bottom handle 2 from the right side of the top surface of the battery pack charging seat body 4, so that the connecting base 3 and the battery pack charging seat body 4 are plugged together, and then, the movable plate 1 is released. 1, at this time, the first compression spring 10 will restore the extension operation after losing the pressure restriction, and push the movable plate 11 upward, and the movable plate 11 moves upward along the first fixing rod 9 through the first connecting hole 12, and then release the hand holding the symmetrical sliding rod 19, and the second compression spring 16 will push the movable rods 17 at both ends in opposite directions after losing the pressure restriction force on both sides, and the movable rods 17 will move along the second fixing rod 15 through the second connecting hole 18 until the clamping block 20 installed on the upper part of the opposite wall of the symmetrical movable rod 17 is inserted into the clamping hole 7 opened on the side wall of the symmetrical connecting block 6 installed on the right side of the connecting base 3, so that after the power tool body 1 is plugged into the battery pack charging seat body 4, it can be connected through the connecting The mechanism 5 further limits the connection between the connecting base 3 and the battery pack charging seat body 4, so as to improve the stability of the power tool body 1 and the battery pack charging seat body 4 after the connection, thereby preventing the power tool body 1 from falling and being damaged when in use or after the battery pack charging seat body 4 is accidentally touched, so as to facilitate the use of the power tool body 1. Finally, if the power tool body 1 needs to be removed from the battery pack charging seat body 4, it is necessary to pinch the symmetrical sliding rod 19 with one hand to remove the card block 20 from the card hole 7, and press the movable plate 11 downward to move the movable rod 17 from the right side of the connecting base 3, and then use the other hand to remove the power tool body 1 plugged into the battery pack charging seat body 4 by pulling it out.
