The elastic plate 4161 is formed when the cut hole 418 is machined. The elastic plate 4161 is thus provided with a simple process and a low manufacturing cost. The elastic plate 4161 protrudes in a direction away from the bottom of the upper connecting seat 41 to form a stopping protrusion 4162, and the end of the stopping protrusion 4162, which contacts the limiting table 423 in the groove 422, is in surface contact, so that the friction force between the stopping protrusion 4162 and the groove 422 is increased, and the limiting effect between the stopping protrusion 4162 and the groove 422 is further improved.

Further, the elastic plate 4161 is a concave plate, and the concave direction of the elastic plate 4161 is opposite to the sleeving direction of the sleeving part 411 of the upper connecting seat 41. In this way, when the upper connecting seat 41 moves relative to the lower connecting seat 42, the elastic plate 4161 does not rigidly collide with the lower connecting seat 42, the curved surface of the elastic plate 4161 is gently contacted with the lower connecting seat 42, and the lower connecting seat 42 slowly compresses the elastic plate 4161 to retract into the cutting hole 418, so that accidental breakage of the elastic plate 4161 is avoided. A groove 422 is concavely formed at the top of the lower hub 42, and a rotation limiting table 423 is formed at a middle position of the groove 422. By this arrangement, the area of the lower connecting seat 42 abutting against the elastic plate 4161 can be reduced, and the time for compressing the elastic plate 4161 by the lower connecting seat 42 can be shortened, so that the elastic plate 4161 is prevented from being broken accidentally.

In addition, the groove 422 is rectangular, and the left and right side walls of the groove 422 are used for limiting the left and right movement range of the abutment table 416. The recess 422 includes oppositely disposed left and right side walls and oppositely disposed front and rear side walls, the abutment pads 416 have a width equal to the distance between the front and rear side walls, and the abutment pads 416 have a length less than the distance between the left and right side walls. The abutment platform 416 is located in the recess 422, the front side wall and the rear side wall form a sliding slot, the abutment platform 416 slides along the sliding slot, and the left side wall and the right side wall limit the sliding range of the abutment platform 416. So configured, the movement of the abutment 416 is limited by the left and right side walls, so that the abutment 416 moves within a predetermined range, thereby avoiding interference with the optional insertion of the locking tongue 417 into the locking hole 421.
