The outer fixed lantern ring 4 that is equipped with of dabber axle sleeve pipe, the part that dabber 1 front end stretches out the dabber sleeve pipe passes fixed lantern ring 4 and with fixed lantern ring 4 between be equipped with the spring 8 that is used for providing the locking power that moves to dabber axle sleeve pipe direction for dabber 1. In the embodiment of the invention, the spring 8 is positioned between the inward flanging at the front end of the fixed sleeve ring 4 and the front end surface of the peripheral bulge of the mandrel 1.
The front end of a spring pressing cylinder 5 which is assembled outside the mandrel sleeve 2 in a sliding mode is located between the mandrel sleeve 2 and the fixed lantern ring 4, a return spring 17 which is used for providing force far away from the fixed lantern ring 4 for the spring pressing cylinder is arranged between the mandrel sleeve 2 and the spring pressing cylinder 5, and a stopping piece which is used for preventing the spring pressing cylinder 5 from being separated from the fixed lantern ring 4 is arranged on the inner periphery of the fixed lantern ring 4.

The pin needle penetrates into the pin hole of the front mandrel, although the rear mandrel cannot rotate due to the matching of the arc concave surface and the positioning steel ball, the front mandrel can rotate freely relative to the rear mandrel, and therefore the front mandrel can rotate according to actual needs when the pin needle penetrates through the pin needle, so that the pin needle penetrates through the pin needle at an angle convenient to operate.
In the embodiment of the invention, a cavity for inserting the front end of the rear mandrel 11 is arranged at the rear end of the front mandrel 10, the nut 12 is in threaded connection with the internal thread at the rear end of the cavity of the front mandrel 10 through external threads, the rear mandrel is rotatably assembled in the nut 12, and the protruding rear end surface at the front end of the rear mandrel 11 is stopped and limited with the front end surface of the nut 12. After the nut is screwed down, a gap of 0.1mm is reserved between the front mandrel and the rear mandrel, so that the mutual rotation of the front mandrel and the rear mandrel is ensured.
The positioning of the rear mandrel is realized by the positioning ball. The positioning balls are evenly distributed on the periphery of the positioning ball in at least three numbers and have strict position relation with the locking balls, the positioning balls are matched with the arc grooves on the rear core shaft and are matched with the arc grooves all the time in the whole movement process of the core shaft, so that the arc grooves of the rear core shaft can be corresponding to the positions of the locking balls all the time, and the locking structure is reused.
