The front and rear sides of the square frame are provided with sliding grooves that extend along the left and right directions of the plastic middle seat base shell 21. The push plate 22 is disposed between the sliding grooves and forms a sliding pair with the square frame. The square frame is provided with a first through hole 23, the axis of which is perpendicular to the length direction of the sliding groove. Two springs 24 are disposed in the square frame, with the springs 24 located to the left of the push plate 22. Between the side and the left inner wall of the square frame, the spring 24 biases the push plate 22 to the right. The right side of the square frame is provided with an opening. The right side of the push plate 22 is provided with friction stripes that extend to the right from the opening. The push plate 22 is provided with two limiting blocks 25.

The axis of the second through hole 27 is parallel to the axis of the first through hole 23. Two wedge blocks 28 are respectively provided on the front and rear inner walls of the second through hole 27.

[0016] The lower outer wall of the button head 1 is provided with two wedge grooves 11 that cooperate with the wedge block 28. The upper end of each of the two wedge grooves 11 is connected to a circumferential slot 12. The lower end of the button head 1 is set in the middle seat assembly 2, and the wedge block 28 is locked in the circumferential slot 12.

[0017] The contact assembly 3 is disposed on the lower side of the plastic base shell 21.

The bottom surface of the plastic base shell 21 is provided with positioning holes (not shown in the figure) that mate with the positioning pins 37.

[0018] Furthermore, the metal insert 31 is made of aluminum alloy.

[0019] Specifically, the wedge block 28, wedge groove 11, etc. in this embodiment all adopt well-known solutions in the prior art, which are already known to those skilled in the art, and will not be described in detail here.

[0020] The working principle of this embodiment:

[0021] When installing the button head 1, insert the button head 1 into the first through hole 23 of the middle seat assembly 2 and through the second through hole 27 in the push plate 22. The wedge groove 11 of the button head 1 pushes the wedge block 28 to the left, causing the push plate 22 to move to the left. The spring 24 is compressed until the wedge block 28 reaches the upper end of the wedge groove 11. The spring 24 returns to its original position, causing the push plate 22 to move to the right, so that the wedge block 28 enters the circumferential groove 12, thereby fixing the button head 1 in the middle seat assembly 2. When disassembling, push the push plate 22 to the left, the wedge block 28 disengages from the circumferential groove 12, and then pull the button head 1 upward, releasing the push plate 22. The spring 24 then causes the push plate 22 to return to its original position.

[0022] The limiting block 25 and the limiting hole 26 work together to limit the travel of the push block to the right.

[0023] After the metal insert 31 is installed into the mounting slot 38 of the middle base, the limiting boss 33 and the limiting stop 32 cooperate to limit its position. The plastic middle base cover is then placed on top. At this point, the plastic middle base cover, the plastic middle base bottom shell 21, and the metal insert 31 form a single unit. The contact assembly 3 is then connected to the metal insert 31 using screws 36. The positioning post 37 cooperates with the positioning hole for positioning, thus firmly connecting the contact assembly 3 to the middle base assembly 2, preventing loosening and reducing the risk of slippage. The insert is made of aluminum alloy, increasing the strength of the middle base assembly 2, providing good structural stability, and ensuring good stability of the threaded connection.

[0024] In this invention, when installing the button head 1, simply inserting the button head 1 into the middle base assembly 2 securely fixes the installation head without requiring any other tools. This simple and convenient operation greatly improves the installation efficiency of the button head 1. After the metal insert 31 is inserted into the mounting groove 38 of the middle base, the limiting boss 33 and the limiting stop 32 cooperate to limit its position. The plastic middle base cover is then placed on top, at which point the plastic middle base cover, the plastic middle base bottom shell 21, and the metal insert 31 form a single unit. The contact assembly 3 is then connected to the metal insert 31 using screws 36, and the positioning post 37 cooperates with the positioning hole for positioning. This securely connects the contact assembly 3 to the middle base assembly 2, preventing loosening and reducing the risk of slippage. The insert is made of aluminum alloy, increasing the strength of the middle base assembly 2, providing good structural stability, and ensuring good stability of the threaded connection.
