By providing the adjusting device 3, the socket 1 and the plug 2 are tightened, and the socket 1 and the plug 2 are prevented from being constantly plugged in and out during long-term use, thereby losing the original tightness, causing the socket 1 and the socket 1 to be easily loosened and damaged, thereby improving the practicality of the device. A protective device 4 is provided on the surface of the socket 1. By providing the protective device 4, the contact of the plug 2 is shielded, and the plug 2 is prevented from being exposed to the air when the plug 2 is connected to the socket 1, so that dust and debris in the outside air are constantly accumulated on the surface of the contact of the plug 2, resulting in poor contact during the connection and use of the socket 1 and the plug 2, thereby improving the practicality of the device.

[0029] The specific settings and functions of the adjusting device 3 and the protective device 4 are described in detail below.

[0030] Reference Figure 2 As shown, in this embodiment: the adjusting device 3 includes an L-shaped plate 31, the L-shaped plate 31 is fixedly connected to the surface of the plug 2, the surface of the socket 1 is fixedly connected to a mounting bracket 32, a screw rod 33 is inserted into the internal thread of the mounting bracket 32, one end of the screw rod 33 is rotatably connected to a limiting block 34, a limiting groove is provided on the surface of the L-shaped plate 31, a sliding rod 35 is slidably inserted into the mounting bracket 32, and one end of the sliding rod 35 is fixedly connected to the limiting block 34. The screw rod 33 rotates in the mounting frame 32, the screw rod 33 drives the limit block 34 to move, and the limit block 34 drives the slide bar 35 to slide in the mounting frame 32, thereby avoiding the limit block 34 from rotating with the rotation of the screw rod 33, thereby improving the stability of the device. A fixed block 36 is fixedly connected to the side of the socket 1 close to the mounting frame 32, and a sliding hole is provided on the surface of the fixed block 36. A semicircular block 37 is fixedly connected to the side of the plug 2 close to the L-shaped plate 31, and a positioning rod 38 is fixedly connected to one side of the semicircular block 37. The positioning rod 38 is slidably connected to the inner surface of the sliding hole of the fixed block 36. Pushing the plug 2 drives the semicircular block 37 to move, and the semicircular block 37 drives the positioning rod 38 to move until the positioning rod 38 slides on the inner surface of the sliding hole of the fixing block 36, so as to achieve the effect of aligning the plug 2 with the socket 1, and avoid the situation of crooked insertion or misaligned insertion when the socket 1 and the plug 2 are connected. The end of the screw rod 33 away from the limit block 34 is fixedly connected with a handle 39, and the size of the limit block 34 is adapted to the size of the limit groove of the L-shaped plate 31. Turning the handle 39 drives the screw rod 33 to rotate in the mounting frame 32, and the screw rod 33 drives the limit block 34 to move, so that the staff can stably rotate the screw rod 33 to accurately control the position of the limit block 34.

[0031] Reference Figure 3 and Figure 4As shown, specifically, the protective device 4 includes two setting blocks 41, and the two setting blocks 41 are fixedly connected to the surface of the socket 1, and the sides of the two setting blocks 41 close to each other are fixedly connected with a long rod 42, and the arc surface of the long rod 42 is rotatably connected with a protective plate 43, and the arc surface of the long rod 42 is sleeved with two torsion springs 44, and the two ends of the torsion spring 44 are respectively fixedly connected to the setting block 41 and the protective plate 43, and one side of the protective plate 43 is fixedly connected with a movable plate 45, and the side of the socket 1 close to the setting block 41 is fixedly connected with a U-shaped frame 46, and a rod 47 is slidably inserted in the U-shaped frame 46, and a slot is provided on the surface of the movable plate 45, and a stopper 48 is fixedly connected to one end of the rod 47. Pull the protective plate 43 to rotate on the arc surface of the long rod 42 until the moving plate 45 is on the inner surface of the U-shaped frame 46, push the stopper 48 to drive the plug 47 to slide on the inner surface of the U-shaped frame 46, until the plug 47 is inserted into the slot of the moving plate 45, so as to achieve the effect of limiting the position of the protective plate 43, and avoid the blocking of the protective plate 43 during the process of the staff connecting the socket 1 and the plug 2, thereby improving the convenience of the device. The arc surface of the plug 47 is sleeved with a spring 49, and the two ends of the spring 49 are respectively fixedly connected to the stopper 48 and the U-shaped frame 46. The fixed plate drives the moving plate 45 to move, and the moving plate 45 is squeezed with the plug 47, and the plug 47 slides in the U-shaped frame 46. At this time, the spring 49 is in a stretched state until the slot of the moving plate 45 is aligned with the position of the plug 47, and the elastic force of the spring 49 drives the plug 47 to slide in the U-shaped frame 46 and automatically insert into the slot of the moving plate 45, thereby improving the convenience of the device.

[0032] Working principle: when the staff reinforces the socket 1 and the plug 2, the semicircular block 37 is moved by pushing the plug 2, and the semicircular block 37 drives the positioning rod 38 to move until the positioning rod 38 slides on the inner surface of the sliding hole of the fixing block 36, thereby achieving the effect of aligning the plug 2 with the socket 1, avoiding the situation of crooked or misplaced insertion when connecting the socket 1 and the plug 2, and turning the handle 39 drives the screw 33 to rotate in the mounting frame 32, and the screw 33 drives the limit block 34 to move, so that the staff can rotate stably. The movable screw 33 accurately controls the position of the limit block 34, and the limit block 34 drives the slide bar 35 to slide in the mounting frame 32, thereby preventing the limit block 34 from rotating with the rotation of the screw 33, thereby improving the stability of the device, until the limit block 34 is inserted into the limit groove of the L-shaped plate 31, the socket 1 and the plug 2 are tightened, thereby preventing the socket 1 and the plug 2 from being constantly plugged in and out during long-term use, thereby losing the original tightness, causing the socket 1 and the socket 1 to become loose and damaged, thereby improving the practicability of the device.

[0033] When the staff needs to shield the contacts of the plug 2, the block 48 drives the plug rod 47 to slide in the U-shaped frame 46 until the plug rod 47 is disengaged from the inner surface of the slot of the movable plate 45, and the torsion of the torsion spring 44 drives the protective plate 43 to rotate on the arc surface of the long rod 42 until the protective plate 43 fits with the surface of the plug 2, thereby achieving the effect of shielding the contacts of the plug 2, avoiding the situation that when the plug 2 is connected to the socket 1, some contacts of the plug 2 are exposed to the air after the plug 2 is connected, so that dust and debris in the outside air will continue to accumulate on the surface of the contacts of the plug 2, resulting in poor contact when the socket 1 is connected to the plug 2, thereby improving the practicability of the device.
