[0008] Preferably, a power detection module is fixedly connected above the push-pull electromagnet on the right side wall of the fixing frame. The top of the power detection module is connected to the adapter body through a wire, and the right side of the power detection module is connected to the push-pull electromagnet through a wire. A support spring is fixedly connected between the inner part of the right side of the fixing frame and the inner wall of the moving frame.

[0009] Preferably, the moving frame is arranged in a "mouth" shape. Guide rods are slidably connected to the front and back sides of the adapter body at the left end of the moving frame. A clamping block is fixedly connected to the right end of the guide rod. Contact blocks are fixedly connected to the front and back side walls of the adapter body above the clamping block. Inclined contact grooves are formed at the bottoms of the contact blocks and the tops of the clamping blocks. A fixing spring is sleeved on the outer surface of the guide rod between the clamping block and the side wall of the moving frame.

[0010] Preferably, the adjusting mechanism includes a limiting frame. The limiting frame is fixedly connected to the inner part of the right side of the fixing frame. A rotating wheel is rotatably connected to the central position inside the limiting frame. A friction ring is fixedly connected to the inner wall of the limiting frame inside the rotating wheel.

[0011] Preferably, tooth plates are slidably connected to the upper and lower sides of the rotating wheel inside the limiting frame. The tooth plates are engaged with the rotating wheel. A top plate is fixedly connected to the bottom of the end of the tooth plate away from the limiting frame. Guide plates are fixedly connected to the left and right sides of the bottom of the fixing frame. A balancing plate is slidably connected to the outer part of the guide plate on the side wall of the top plate. The balancing plate is fixedly connected to the top plate. A clamping plate is slidably connected to the inner part of the end of the top plate away from the tooth plate. The clamping plate is arranged in an "L" shape. A connecting spring is arranged above the center position of the clamping plate on the top plate.

[0012] Preferably, a data cable is plugged into the top of the adapter body. Pressing blocks are arranged on the left and right sides of the top of the adapter body. A power display screen is fixedly connected to the top front of the adapter body.

[0013] A usage method of a wax spraying device for wooden furniture processing includes the following steps:

[0014] S1: First, the device is connected to the upper and lower ends of an external socket through the top plate and the clamping plate. At the same time, under the action of the tooth plate and the rotating wheel, the fixing frame is limited to the central position of the external socket.

[0015] S2: When charging, press down the adapter body to connect it to the socket. At the same time, the adapter body is limited by the clamping block and the contact block.

[0016] S3: When it is necessary to stop charging midway, manually push the moving frame. The moving frame drives the clamping block to move through the guide rod, and the contact block is disengaged from the limit of the clamping block. The adapter body moves upward under the action of the reset spring to cut off the power supply.

[0017] S4: After the power detection module detects that the power is fully charged, it transmits an electrical signal to the push-pull electromagnet. The push-pull electromagnet drives the moving frame to move quickly. The moving frame drives the clamping block away from the contact block through the guide rod. At this time, the adapter body quickly rebounds under the action of the return spring and moves away from the socket, completing the power-off.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The power adapter with overcharge prevention function is connected to the socket by pressing down the adapter body. At the same time, the adapter body drives the contact block to move below the clamping block. At this time, the adapter body is limited. The power display screen displays the charging amount. After the power detection module detects that the power is fully charged, it transmits an electrical signal to the push-pull electromagnet. The push-pull electromagnet drives the moving frame to move quickly. The moving frame drives the clamping block away from the contact block through the guide rod. At this time, the adapter body quickly rebounds under the action of the return spring and moves away from the socket, completing the power-off. This solves the problem that the existing wall-mounted power adapter does not have an automatic power-off function, resulting in damage to electronic devices caused by long-term power connection of the wall-mounted power adapter and electronic devices, and has the advantage of automatic power-off.

[0020] 2. The power adapter with overcharge prevention function holds the top plates on both sides of the adapter body with both hands, with fingers buckling the bottom wall of the top plates, and presses down the clamping plate with the thumb while pushing the top plates to move. The top plates move synchronously under the action of the toothed plate on the rotating wheel until the bottom of the clamping plate is inserted below the external socket, and the top plates are closely attached to the top wall of the external socket under the action of the connecting spring, which has the advantage of facilitating the limitation of the adapter.

When charging, press down the adapter body 1 to connect it with the socket. At the same time, the adapter body 1 drives the contact block 12 to move below the locking block 11. At this time, the adapter body 1 is limited. The power display screen 24 displays the charging amount. After the power detection module 8 detects that the power is full, it transmits an electrical signal to the push-pull electromagnet 7. The push-pull electromagnet 7 drives the moving frame 6 to move quickly. The moving frame 6 drives the locking block 11 away from the contact block 12 through the guide rod 10. At this time, the adapter body 1 quickly rebounds under the action of the reset spring 5 and moves away from the socket to complete the power-off.
