In this embodiment, the adapter platform portion 4 is in the shape of a frustum of a cone integrally injection molded with the upper shell 1. The frustum-shaped adapter platform portion 4 is hollow and provided with ribs. The outer peripheral surface of the adapter platform portion 4 has an external adapter thread.

[0024] A locking pin 5 that can extend out of the lower end surface of the upper shell 1 is provided on one side of the lower part of the upper shell 1 where the adapter platform portion 4 is located, and a locking spring 6 for making the locking pin 5 extend out of the lower end surface of the upper shell 1 is sleeved on the locking pin 5. Specifically, a groove with an open upper end is provided on one side of the upper shell 1 where the adapter platform portion 4 is located, and this groove is integrally injection molded with the upper shell 1. A jack is provided at the bottom end of the groove, and the locking pin 5 is installed in the jack. A flange is provided on the locking pin 5 and is located in the groove. The flange is a circumferential portion that protrudes from the outer peripheral surface of the locking pin 5 and is integral with the locking pin 5. The upper end opening of the groove is provided with an end cover 7, and the end cover 7 is threadedly fitted at the opening part of the groove of the upper shell 1. The locking spring 6 is sleeved on the locking pin 5, the locking spring 6 is located in the groove, the lower end of the locking spring 6 presses against the flange of the locking pin 5, and the upper end of the locking spring 6 presses against the end cover 7. The locking spring 6 is a compression spring, which provides pressure for the locking pin 5 to protrude out of the lower end surface of the upper shell 1.

[0025] An adapter groove 2-1 is provided at the center position of the lower shell 2, and the shape of the adapter groove 2-1 matches the shape of the adapter platform portion 4.

[0035] A locking pin 5 that can extend out of the lower end surface of the lower plate seat 1-2 is provided on one side of the lower part of the lower plate seat 1-2 where the adapter table portion 4 is located. A locking spring 6 for making the locking pin 5 extend out of the lower end surface of the lower plate seat 1-2 is sleeved on the locking pin 5. Specifically, a groove with an open upper end is provided on one side of the lower plate seat 1-2 where the adapter table portion 4 is located, and this groove is integrally injection-molded with the lower plate seat 1-2. A jack is provided at the bottom end of the groove, and the locking pin 5 is installed in the jack. A flange is provided on the locking pin 5 and is located in the groove. The flange is a circumferential portion that is integral with the locking pin 5 and protrudes from the outer peripheral surface of the locking pin. An end cover 7 is installed at the open upper end of the groove, and the end cover 7 is threadedly fitted at the opening part of the groove of the lower plate seat 1-2. The locking spring 6 is sleeved on the locking pin 5, the locking spring 6 is located in the groove, the lower end of the locking spring 6 presses against the flange of the locking pin 5, and the upper end of the locking spring 6 presses against the end cover 7. The locking spring 6 is a compression spring, and it provides pressure for the locking pin 5 to protrude from the lower end surface of the lower plate seat 1-2.

[0036] An adapter groove 2-1 is provided at the center position of the lower shell 2, and the shape of the adapter groove 2-1 matches the shape of the adapter table portion 4. An internal adapter thread adapted to the external adapter thread is provided on the inner circumferential surface of the adapter groove 2-1. A pin hole 2-2 that is engaged with the top end of the locking pin 5 is provided on one side of the lower shell 2 where the adapter groove 2-1 is located.

[0037] The adapter table portion 4 of the lower plate base 1-2 is aligned with the adapter groove 2-1 of the lower shell 2 and inserted into the adapter groove 2-1. Rotate the upper shell 1 to thread-connect the adapter table portion 4 of the lower plate base 1-2 with the lower shell 2. When the front ends of the lower plate base 1-2 and the lower shell 2 coincide after rotation, the locking pin 5 of the lower plate base 1-2 is aligned with the pin hole 2-2 of the lower shell 2, and the locking pin 5 automatically pops out and inserts into the pin hole 2-2 of the lower shell 2, thereby realizing the locking of the upper shell 1 and the lower shell 2. In this embodiment, to ensure the fastest installation to the greatest extent, the rotatable angle between the adapter table portion 4 and the adapter groove 2-1 is 90°, that is, the designed length of the thread requires that after the lower plate base 1-2 and the lower shell 2 are rotated by 90°, the end faces of the lower plate base 1-2 and the lower shell 2 are in contact and pressed tightly, and in the state of end-face pressing, the front ends of the lower plate base 1-2 and the lower shell 2 are aligned, and the positions of the locking pin 5 and the pin hole 2-2 are aligned.

[0038] In this embodiment, a boss is provided on the upper end face of the lower shell 2 corresponding to the position of the pin hole 2-2, and the outer edge of the boss is in the shape of an arc chamfer.
