[0017] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present invention and are for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific direction.

[0018] Please refer to the instruction manual Figure 1-6 , the present invention provides a technical solution: Embodiment 1, a safe electric power supply device, comprises a shell 9 with a groove 7 on the upper surface, a plurality of sockets 10 are arranged in series in the groove 7 of the shell 9 along the length direction of the shell 9, a support plate 3 located on the upper part of the plurality of sockets 10 can be detachably installed in the groove 7, a plurality of mounting openings 5 ​​corresponding to the plurality of sockets 10 are arranged on the surface of the support plate 3, a movable plate 4 which can be slidably adjusted left and right along the length direction of the shell 9 is arranged in the mounting opening 5, specifically, guide rods 16 which are perpendicular to the side walls and correspond to each other are arranged on the left and right inner walls of the mounting opening 5, connecting holes 19 corresponding to the guide rods 16 are arranged on the two side walls of the movable plate 4, wherein the hole depth of the connecting hole 19 is greater than the length of the guide rod 16, which ensures that the movable plate 4 can effectively slide left and right, and the spacing between the corresponding guide rods 16 is slightly smaller than the length of the movable plate 4, which ensures that the movable plate 4 can be effectively plugged in and replaced later; The surface of the movable plate 4 is provided with a socket B6 corresponding to the corresponding socket 10 at the bottom. The socket B6 on the surface of the movable plate 4 is respectively connected or staggered with the corresponding socket 10 at the bottom as the movable plate 4 slides back and forth. Specifically, when plugging in the power supply on a daily basis, the movable plate 4 slides to one side of the installation port 5, and the socket B6 on the movable plate 4 is staggered with the corresponding socket 10 at the bottom, which realizes the shielding protection of the socket 10, not only avoiding the occurrence of accidental electric shock accidents, but also preventing dust and debris from falling into the socket 10 and affecting the normal use of the socket 10. The upper part of the support plate 3 can also be detachably installed with a top plate 1 adapted to the notch of the groove 7, and the surface of the top plate 1 is provided with a plurality of sockets A2 corresponding to and connected with a plurality of sockets 10 one by one; When the power plug is needed, just insert the power plug into the socket A2 of the top plate 1 first. Since the diameter of the socket A2 must be slightly larger than the size of the power plug, when the power plug contacts the movable plate 4, the power plug can be used to gradually push the movable plate 4 until the socket B6 on the movable plate 4 is connected with the lower socket 10, and the power plug and the socket 10 can be connected.

[0019] Embodiment 2: During the long-term use of the extension strip, since the extension strip is mostly made of plastic, it is very easy to be damaged after oxidation corrosion, especially in the process of repeatedly plugging and unplugging the power plug, it is very easy to cause the end face of the extension strip to be broken. Although the setting of the support plate 3 and the top plate 1 greatly improves the strength of the end face of the extension strip, in order to avoid the disassembly and replacement of the support plate 3 or the top plate 1 after accidental damage, the inner wall of the groove 7 is provided with a reduced diameter step 8 arranged around the inner wall, and the step surface of the reduced diameter step 8 is in the same plane with the upper end face of the socket 10. The support plate 3 and the top plate 1 are both detachably installed in the groove 7 through the reduced diameter step 8, and the upper surface of the top plate 1 is in the same plane with the notch of the groove 7. The detachable connection between the support plate 3 and the top plate 1 can be completed by screwing through the top plate 1 and the support plate 3 in sequence and then threading them with the reduced diameter step 8. During subsequent replacement, the disassembly and assembly can be completed by simply unscrewing the screws.

[0020] Embodiment 3, in order to ensure that the movable plate 4 can effectively shield and protect the lower socket 10 when the power plug is plugged in, a spring 17 is sleeved on the rod body of the guide rod 16 on either side of the installation opening 5, and the two ends of the spring 17 are respectively in conflict with the side wall 4 of the movable plate and the inner wall of the installation opening 5. The elastic limit of the movable plate 4 by the spring 17 makes the movable plate 4 always on one side of the installation opening 5, and the socket B6 on the movable plate 4 is staggered with the lower socket 10, which can effectively shield the lower socket 10; In order to facilitate the pushing of the movable plate 4 and the subsequent plugging and power supply of the power plug, the lower side wall of the support plate 3 is provided with several long through holes A18 which are arranged along the length direction of the shell 9 and correspond one-to-one with the several installation holes 5. The lower side wall of the shell 9 is provided with several long through holes B11 which correspond one-to-one with the several long through holes A18. The corresponding long through holes B11 and the long through holes A18 are provided with push rods 22 for pushing the movable plate 4 to slide. The movable plate 4 is pushed to move by the push rod 22. When the socket B6 on the movable plate 4 corresponds to the socket 10 at the bottom, the power plug can be plugged in and the power supply can be completed quickly and conveniently.

[0021] In the fourth embodiment, although the arrangement of the push rod 22 facilitates the plugging of the power plug, it also facilitates the pushing of the movable plate 4 by children, which may easily expose the socket 10 and cause the risk of electric shock. For this reason, a tapered groove 20 which is wide outside and narrow inside is arranged on the lower side wall of the movable plate 4, and a slot 21 which is plugged and matched with the push rod 22 is arranged on the inner bottom surface of the tapered groove 20. One end of the push rod 22 is plugged and connected with the slot 21, and the other end of the push rod 22 protrudes to the outside of the long through hole B11. The push rod 22 can be disassembled and stored to prevent children from pushing the movable plate 4. When the power plug needs to be plugged, the push rod 22 is taken out and inserted into the tapered groove 20 through the long through hole B11 and the long through hole A18 in turn. The push rod 20 can be used to guide the push rod 20 to quickly and accurately insert into the slot 21, which greatly facilitates the subsequent pushing of the movable plate 4. In order to facilitate the storage of the push rod 22 and avoid the loss of the push rod 22, a slot 12 for storing the push rod 22 is provided on one side of the shell 9. One end of the slot 12 is an open structure, and the open setting facilitates the disassembly and assembly of the push rod 22.

[0022] Embodiment 5: The power strip is often placed on the ground or on a desktop. When placed on the ground, the power strip is easily displaced due to the lack of a fixing mechanism, which affects the stable connection between the power plug and the power strip. When placed on a desktop, it not only occupies the desktop area but also looks ugly. For this reason, a bottom plate 13 is detachably installed at the lower part of the shell 9. Specifically, a plurality of connecting members 14 are evenly distributed on the upper surface of the bottom plate 13. The connecting member 14 includes a connecting rod 24 perpendicular to the bottom plate 13 and an enlarging head 23 at the end of the connecting rod 24. The shell The lower surface of the housing 9 is provided with a plurality of L-shaped slots 27 corresponding to the connecting member 14 one by one. The slot width of the L-shaped slot 27 is adapted to the diameter of the enlarging head 23. The notch of the L-shaped slot 27 is provided with an inner folding edge 28 for blocking and limiting the enlarging head 23 inserted into the L-shaped slot 27. One end of the notch of the L-shaped slot 27 is provided with an enlarging opening 29 adapted to the enlarging head 23. The plug-in cooperation between the connecting member 14 and the L-shaped slot 27 can not only ensure the stability of the connection between the housing 9 and the bottom plate 13, but also facilitate the subsequent disassembly of the housing 9. Screw holes 25 that penetrate the bottom plate 13 are provided at each top corner of the upper surface of the bottom plate 13, and studs 26 that are threadedly connected to the screw holes 25 are provided on the upper part of the suction cup 15. When the extension strip needs to be installed on a desktop, tile or floor, the suction cup 15 can be used to effectively adsorb and fix it. The adsorption and fixing method can also be used to install it to the table legs, saving desktop area. When the extension strip needs to be installed on the wall, it only needs to remove the suction cup 15 to expose the screw holes 25, and the bottom plate 13 can be installed on the wall by passing the screws through the screw holes 25, thereby facilitating the subsequent installation of the shell 9 on the wall.
