[0030] In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] In one embodiment of the present invention, Figure 1-5 As shown, a charging stand for an electric tool is provided, comprising an upper shell 10 and a lower shell 20. A downwardly recessed fixing groove 11 is provided on the top surface of the upper shell 10. A charging chamber 12 extends downward in the fixing groove 11, and a plurality of equally spaced guide strips are provided in the charging chamber 12. A snap-fit ​​structure 30 for snapping with the electric tool is provided on both sides of the fixing groove 11. An elastic member 40 is provided at one end of the fixing groove 11, and the elastic member 40 is an elastic sheet. A first protrusion 41 protruding outward is provided on the elastic member. The lower shell 20 is provided below the upper shell 10, and the lower shell 20 is connected to the upper shell 10. A plurality of circumferentially distributed connection terminals 50 are provided in the charging chamber 12, and the connection terminals 50 have a second protrusion 51 protruding outward. The second protrusion 51 is passed through the side wall of the charging chamber 12 and extends into the charging chamber 12.

[0032] By providing the snap-fit ​​structure 30, the elastic member 40 and the second protrusion 51, when charging, the power tool is inserted into the charging cavity 12. When the connecting terminal 50 contacts the connecting end of the power tool, the outer side of the power tool is initially fixed by the second protrusion 51, and then the first protrusion 41 of the elastic member 40 is engaged with the side of the power tool, so that the power tool can be locked in the charging base to avoid loosening. At the same time, the snap-fit ​​structure 30 is further locked with both sides of the power tool to prevent the power tool from easily detaching from the charging base, thereby improving the installation stability between the charging base and the power tool.

[0033] Preferably, the buckle structure 30 includes a boss 31. A first groove 32 that is recessed inward is provided at the bottom end of the boss 31. A block 33 is provided at the top of the boss 31. An inclined surface is provided at the top of the block 33. Two groups of second grooves 34 that are recessed downward are provided on the block 33. The two groups of second grooves 34 are distributed left and right in the block 33. A first slot is provided on the upper shell 10 corresponding to the boss 31. The first slot is connected to the first slot 32. When the buckle structure 30 is buckled with the power tool, the buckle on the side of the power tool enters the first groove 32 under the guidance of the inclined surface and the second groove 34. At this time, the block 33 and the buckle are buckled with each other, locking the power tool on the charging stand to prevent the power tool from loosening or falling when the charging stand is hit, thereby improving the installation stability between the charging stand and the power tool.

[0034] Preferably, the elastic member 40 includes a connecting portion 401 and a reinforcing portion 402. The connecting portion 401 is disposed within the upper housing 10. The reinforcing portion 402 is vertically disposed on one side of the connecting portion 401 and connects to the first protrusion 41. The first protrusion 41 and the reinforcing portion 402 are arranged at an angle. The provision of the reinforcing portion 402 improves the connection strength of the elastic member 40, thereby increasing the service life of the elastic member 40.

[0035] Furthermore, the first protrusion 41 includes a first inclined portion 411 and a first clamping portion 412. The first inclined portion 411 is obliquely connected to the reinforcing portion 402, and the first inclined portion 411 has a certain elastic effect. The first clamping portion 412 is connected to the first inclined portion 411, and the first clamping portion 412 is in a "V"-shaped structure. When the power tool is inserted into the charging base, the first clamping portion 412 is snapped into the slot at one end of the power tool under the action of the first inclined portion 411, so that the first clamping portion 412 and the slot are mutually clamped, thereby locking the power tool in the charging base, preventing the power tool from loosening or falling when the charging base is hit, and improving the installation stability between the charging base and the power tool.

[0036] Furthermore, two sets of outwardly extending reinforcement sheets 403 are provided on the reinforcement portion 402. The two sets of reinforcement sheets 403 are symmetrically distributed on both sides of the reinforcement portion 402. By providing the reinforcement sheets 403, the overall structural strength of the reinforcement portion 402 is enhanced, thereby increasing the service life of the elastic member 40.

[0037] Preferably, the connecting terminal 50 includes a horizontal portion 501 and a vertical portion 502. The vertical portion 502 is vertically arranged on one side of the horizontal portion 501 and connected to the second protrusion 51. The second protrusion 51 is arranged obliquely to the vertical portion 502. One end of the second protrusion 51 is connected to the vertical portion 502, and the other end is suspended, so that the second protrusion 51 has a certain rebound effect. When the power tool is plugged into the charging base, the second protrusion 51 can contact each other with the side of the power tool, so that the power tool can be stably fixed in the charging base, playing a certain fixing role, and preventing the power tool from becoming loose between the power tool and the charging base or the power tool from falling easily.

[0038] Furthermore, the second protrusion 51 includes a second inclined portion 511 and a third inclined portion 512. The second inclined portion 511 is obliquely connected to the top of the vertical portion 502. The third inclined portion 512 is obliquely connected to the bottom of the second inclined portion 511. The second inclined portion 511 and the third inclined portion 512 are arranged at an obtuse angle, that is, a "V"-shaped structure. By arranging the second inclined portion 511 and the third inclined portion 512 at an obtuse angle, the second protrusion 51 is in point contact with the side of the power tool, and the force on the second protrusion 51 can be concentrated on one point, thereby improving the clamping stability of the power tool, and thereby improving the connection stability between the power tool and the charging base.

[0039] Preferably, a circuit board 21 is provided in the lower housing 20. Two groups of indicator lights 22 are provided on the circuit board 21. The connection terminal 50 is electrically connected to the circuit board 21. By providing the indicator lights 22, it is convenient for the staff to timely understand the charging status of the power tool.

[0040] Preferably, the bottom of the lower shell 20 is provided with multiple groups of evenly spaced heat dissipation holes 23. A thermal conductive layer and an anti-slip layer 24 are also provided at the bottom of the lower shell 20. The thermal conductive layer is provided above the heat dissipation holes 23, and the anti-slip layer 24 is provided below the heat dissipation holes 23. By providing the thermal conductive layer and heat dissipation holes 23, the heat generated during charging is quickly transferred into the heat dissipation holes 23 through the thermal conductive layer, and then transferred to the outside through the heat dissipation holes 23, thereby preventing safety hazards caused by excessive internal temperatures of the charging station. Furthermore, the provision of an anti-slip pad increases the friction between the bottom surface of the charging station and the contact surface, thereby improving the placement stability of the charging station.

[0041] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the above-disclosed technical contents without departing from the scope of the technical solution of the present invention.
