All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1:

[0023] Please refer to Figures 1 to 5 As shown, a universal socket that is convenient for replacement includes a female seat 1. A connecting seat 2 is fixedly connected to the top of the female seat 1. A socket joint 3 is fixedly connected to the top of the connecting seat 2. A sleeve pipe 4 is threadedly connected to the surface of the connecting seat 2. An adjusting cavity 5 is rotatably provided on the surface of the sleeve pipe 4. Four trapezoidal grooves 6 are opened inside the adjusting cavity 5. A square groove 12 is opened at the bottom of the female seat 1. Four clamping plates 11 are arranged inside the square groove 12. Through the setting of the female seat 1, the square groove 12 can be opened. Through the setting of the connecting seat 2, the sleeve pipe 4 can be screwed on its surface. Through the setting of the adjusting cavity 5, the trapezoidal grooves 6 can be opened. Through the opening of the trapezoidal grooves 6, when the adjusting cavity 5 descends, the push rod 8 can be squeezed, so that the two push rods 8 in the same direction can move towards each other. Through the opening of the square groove 12, the connecting shaft of the electric tool can be put into it. Through the setting of the clamping plates 11, when the connecting shaft of the electric tool is relatively small, it can be clamped and fixed by the clamping plates 11 at this time.

[0024] Four transverse grooves 7 are opened at the top of the female seat 1. Push rods 8 are arranged inside the transverse grooves 7. Through the opening of the transverse grooves 7, the push rods 8 can move inside them.

[0025] Limit grooves 9 are opened on the inner side walls of the transverse grooves 7, and the push rods 8 are slidably connected inside the limit grooves 9. Through the opening of the limit grooves 9, the push rods 8 play a certain guiding and limiting role when moving.

[0026] Embodiment 2:

[0027] Please refer to Figure 1 、 Figure 4 and Figure 5 As shown, a round hole is opened inside the clamping plate 11. A connecting cylinder 13 is fixedly connected inside the round hole. A fastening nut 14 penetrates through the clamping plate 11. Through the setting of the connecting cylinder 13, the clamping rod 10 can move more smoothly inside it, and it is also convenient for subsequent removal. Through the setting of the fastening nut 14, the clamping rod 10 can be fixed after being inserted into the connecting cylinder 13.

[0028] The bottom end of the push rod 8 is fixedly connected with a clamping rod 10, and the surface thread of the fastening nut 14 penetrates through the inside of the clamping rod 10.
