A first thrust portion 312, a second thrust portion 313, and a third thrust portion 314 are provided on the circumferential side of the first sleeve 310, and a fourth thrust portion 322 and a lock groove 321 are provided on the circumferential side of the second sleeve 320. The locking member 400 is slidably disposed on the housing assembly 100, and the locking member 400 is provided with a second thrust surface 410, a third thrust surface 420 and a locking part 430, wherein the second thrust surface 410 is disposed opposite to the third thrust surface 420. The square bar holes 311 are adapted to the first and second

square bars

510 and 520 so that the first and second

square bars

510 and 520 can be inserted into the square bar holes 311.

Referring to fig. 2, the first dial sleeve 310 is provided in two, two first dial sleeves 310 are respectively provided on two sides of the second dial sleeve 320, and the square rod hole 311 on the first dial sleeve 310 is aligned with the square rod hole 311 on the second dial sleeve 320.
