detailed description

As shown in Figures 1 and 2, the utility model includes a plug main body 7, a first insert 1, a second insert 8, an insert protection block 2 and a power cord 5, and the lower part of the plug main body 7 is provided with a cavity 9, the insert protection block 2 is installed on the installation cavity 9 and can slide up and down relative to the plug body 7, the upper ends of the first insert 1 and the second insert 8 both extend into the install cavity 9, the The upper ends of the first insert 1 and the second insert 8 are fixedly connected to the plug body 7, and the lower ends of the first insert 1 and the second insert 8 pass through the insert protection block 2 and the insert protection block 2 It can slide up and down relative to the first insertion piece 1 and the second insertion piece 8, the lower ends of the first insertion piece 1 and the second insertion piece 8 are located outside the plug body 7, and the installation cavity 9 is provided with an elastic member 6, Both ends of the elastic member 6 are tightly pressed against the top of the insert protection block 2 and the plug body 7 respectively, and the upper ends of the first insert 1 and the second insert 8 are connected to one end of the power cord 5, so The other end of the power cord 5 passes through the plug main body 7 , and the two sides of the plug main body 7 are symmetrically installed with limiting members 3 for limiting the insertion piece protection block 2 .

As shown in Fig. 1 and Fig. 2, the upper part of the plug body 7 is provided with a round hole 4 which is convenient for manual operation, which is convenient for applying force and is not prone to slipping.

In this embodiment, the diameter of the circular hole 4 is 18 mm to 22 mm, which is basically similar to the width of a human finger, so that it is convenient for a human finger to insert.
