It is understood that the base 141 is placed on the bottom wall. In this embodiment, a portion of the gear 143 is located inside the cavity 131, and another portion of the gear 143 extends through the opening 132, i.e., another portion of the gear 143 is located outside the cavity 131. The cover 150 is detachably covered on the opening 132, as shown in fig. 1 and 3, a side wall 151 of the cover 150 is provided with a stopper 152, and after the cover 150 is covered on the opening 132, the stopper 152 is located between two teeth of the gear 143 to prevent the gear 143 from rotating.
In view of the above, the working principle of the adapter 100 is: in order to facilitate the removal of the root canal, only the gear 143 needs to be rotated, and the gear 143 drives the rack 142 to move, so that the base 141 is lifted to abut against the root canal, and the root canal can be pushed away from the adapter 100 by the upward pushing force. While the root canal assist extraction mechanism 140 prevents movement of the gear 143 and rack 142 when not in use by the stop 152 on the cover 150. When the root canal auxiliary pulling mechanism 140 is needed, the cover 150 is opened, the cooperation between the stop 152 and the gear 143 is released, and the adapter 100 is convenient and safe to use.
It should be noted that, in the present embodiment, the manner in which the cover 150 is detachably covered on the opening 132 is not limited, for example, the annular wall 133 of the connector 130 is provided with a threaded hole, the cover 150 includes a connecting wall protruding from the main body of the cover 150, the connecting wall is provided with a hand-screwed bolt, and the detachable connection is achieved by using the cooperation of the threaded hole and the hand-screwed bolt; or by using the structure of the conventional cover 150, one end of the cover 150 is hinged with the annular wall 133 of the connector 130, and the other end is clamped with the annular wall 133 of the connector 130.
Specifically, as shown in fig. 2 and 3, in one implementation of the present embodiment, the stopper 152 is a stopper rod, and both ends of the stopper rod are connected to both ends of the cover 150 in the body width direction, respectively. The width direction of the body referred to herein means a direction perpendicular to the paper surface of fig. 1. In another implementation of this embodiment, the stopper 152 is a stop piece, one end of which is connected to the side wall 151 of the cover 150 opposite the opening 132, and the other end of which is located between two teeth of the gear 143.
Referring again to fig. 1, preferably, the other side of the base 141 is provided with a guide 144, and the inner wall of the coupling head 130 is provided with a guide rail disposed along the height direction of the body, and the guide 144 is engaged with the guide rail. By using the cooperation of the guide 144 and the guide rail, the base 141 can be stably moved up and down along a straight line.
Further, the adaptor 101 further includes an adaptor 110, and the adaptor 110 includes a mounting portion 112 and an adaptor portion 111 having elasticity. The adapter 111 includes a mating channel 111a. The insertion channel 111a allows insertion of a root canal. Both ends of the mounting portion 112 are connected to the adapter 111 and the connector 130, respectively. In this embodiment, the adapter 111 may be rubber or made of a metal material having elasticity. The mounting portion 112 is made of metal.
Preferably, the body further includes a mating cap 102, and the outer wall of the mounting portion 112 is provided with external threads 112a. The inner wall of the mating cap 102 is provided with internal threads that mate with the external threads 112a.

Meanwhile, the spring 115 is connected to the second fixing member 113b. That is, since the fitting cap 102 and the mounting portion 112 are screwed together, it is necessary to rotate the fitting cap 102 to fix the fitting cap 102 to the mounting portion 112, and it is possible to prevent the second fixing member 113b from rotating relative to the first fixing member 113a in order to prevent the spring 115 from being broken during the rotation of the fitting cap 102.
In another implementation manner of this embodiment, as shown in fig. 1, the fixing member 113 is sleeved on the fixing end, the fixing member 113 includes a first fixing member 113a and a second fixing member 113b, the first fixing member 113a is fixedly connected with the fixing end, the first fixing member 113a and the second fixing member 113b are respectively provided with an annular track, the first fixing member 113a and the second fixing member 113b are connected through an "i-shaped" connecting nail 116, the connecting nail 116 is matched with the annular track, and the spring 115 is connected to the second fixing member 113b. At this time, the second fixing member 113b is also rotatable with respect to the first fixing member 113 a. Preferably, the second end 122 is provided with a recess that mates with the tip of the connecting pin 116. That is, the mating cap 102 can be mated with the connecting pin 116 to achieve a seamless connection when the mating cap 102 is mated with the mounting portion 112.
Preferably, an elastomeric washer is attached to the inner sidewall 151 of the second end 122. After the fitting cap 102 and the mounting portion 112 are fitted, the elastic washer abuts against the outer sidewall 151 of the mounting portion 112 to prevent the fitting cap 102 from loosening.
