The ferrule 11 is provided with a accommodating groove 111 and a buckle groove 113. The buckle groove 113 is embedded in a C-shaped buckle 40. The fixing ring 30 is provided with a magnetic body 31. The fixing ring 30, the magnetic body 31 and the elastic member 20 are received in the accommodating groove 111, and the elastic member 20 is abutted against the flange 14 and After the main body 10 is inserted into the buckle 40, the main body 10 is attached to the buckle 40, so that the main body 10 can suck the screw 52 due to the action of the magnetic body 31, and can be prevented during operation. The screwing member 52 is dropped at the receiving groove 111 of the body 10.

But the lack of the patent is based on:

1. The maximum outer diameter of the fixing ring 30 is larger than the inner diameter of the buckle 40. When the assembly is basically set, the buckle 40 is fastened to the buckle groove 113, and the fixing ring 30 is less rigid, so that The retaining ring 30 is inserted into the receiving slot 111 through the retaining ring 40, so that the retaining ring 30 needs to be pressed into the retaining ring 30 to pass the retaining ring 40. When the ring 30 is pressed hard through the buckle 40, it is easily damaged, and the operator is inconvenient in assembling the operation.

2. The buckle groove 113 has different sizes according to the size of the body 10.

3. Please refer to the figure 16 for the structure of the patent case. The fitting part 11 is in the form of a hexagonal groove. If the fitting part 11 is 19 mm in size, the fitting part 11 The inner cut diameter is 19MM, the inner diameter of the buckle groove 113 is matched with the distance of 19MM two diagonal ends, when the two sides of the hexagon are 19MM, the two diagonals are 21.93MM, so the inner diameter of the buckle groove 113 Preferably, the fixing ring 30 is accommodated in the fitting portion 11. The maximum outer diameter of the fixing ring 30 is also 19 mm, and the minimum outer diameter can be set to 18 mm, so that the outer diameter of the buckle 40 is 23 mm. The inner diameter is 18 mm, so that the width of the buckle 40 is 2.5 mm, and the buckle 40 of the larger width is relatively difficult to retract and is buckled at the buckle groove 113.
