As a variation, the body 22 and shoulder 24 may be integrally formed, or may be connected by an interference fit or other means.

The neck 4 is provided with a central bore 40 which is connected to the shoulder 24 near the end of the shank 2, and the neck 4 may be connected to the shoulder 24 by a threaded connection by providing an external thread at the end near the shank 2 and an internal thread at the bore 240 of the shoulder 24. First clamping head 82 connects in the one end that stalk portion 2 was kept away from to neck 4, first clamping head 82 is equipped with connecting hole 822, connecting hole 822 is equipped with the internal thread, the one end that stalk portion 2 was kept away from to neck 4 is equipped with the external screw thread, is connected first clamping head 82 and neck 4 through threaded connection.

As a variant, the neck 4 and the shoulder 24 may be connected by an interference fit or other means; the first gripping head 82 and the neck 4 may also be connected by an interference fit or other means.

The force applying mechanism 6 includes an elastic member 62, a force applying member 64 abutting against one end of the elastic member 62, and a connecting rod 66 connected to the force applying member 64. The resilient member 62 is a spring and is located within the body 22. The force application member 64 is movably located within the tube 22. The elastic member 62 abuts against the force applying member 64 at one end and the shoulder 24 fixedly connected to the tube 22 at the other end, thereby applying an elastic force to the force applying member 64, and the force applying member 64 transmits the elastic force to the connecting rod 66. The outer peripheral surface of the force application member 64 is provided with a groove 642. The connecting rod 66 passes through the central bore 40 of the neck 4 and its end remote from the shank 2 extends out of the central bore 40 of the neck 4 to connect to a second clamping head 84. The second clamping head 84 is provided with a mounting hole 842, and one end of the connecting rod 66 far away from the handle 2 is mounted in the mounting hole 842 through interference fit or threaded fit. In this embodiment, the number of the grooves 642 is two, and the grooves are located on opposite sides of the outer peripheral surface of the urging member 64.

As a variation, the force applying member 64 and the connecting rod 66 may be connected by an interference fit or other means; the second clamping head 84 and the connecting bar may be connected in other ways.

First holding head 82 sets up with second holding head 84 relatively, and is equipped with the portion of gripping that a pair of curved centre gripping groove 86 held the root canal file in order to form accommodation space 88 relatively, and first holding head 82 and second holding head 84 are equipped with the shrinkage pool of the portion of gripping that protruding 89 is used for inserting the root canal file respectively on its centre gripping groove 86, and the root canal file takes place to rotate and drops when preventing centre gripping root canal file.

The release member 9 includes a pressing portion 92 and a mounting portion 94 connected to the pressing portion 92. The mounting portion 94 is mounted in the recess 642 of the biasing member 64 through the side hole 222 of the body 22. The pressing portion 92 is located on the side of the tube 22. The side hole 222 is a bar shape, and the mounting portion 94 is movable in the side hole 222. The pressing portion 92 is covered on the side hole 222. In this embodiment, the number of the release elements 9 corresponding to the two side holes 222 and the two grooves 642 is 2, and functionally, one release element 9 can be implemented. In this embodiment, one side of the mounting portion 94 of the releasing element 9 abuts against the hole wall of the side hole 222 away from the shoulder 24, and the other side abuts against the groove wall of the groove 642 of the force applying element 64, so that the force applying element 64 can be limited from moving in the direction away from the shoulder 24 under the action of the elastic force of the elastic element 62, and the elastic element 62 can have an initial compression amount to apply a pre-tightening force to the force applying element 64. As a modified embodiment, a stopper structure for restricting the movement of the biasing member 64 in the direction away from the shoulder 24 may be provided separately to the pipe body 22.

In the inoperative state, the second gripping head 84 is brought closer to the first gripping head 82 by the force applying mechanism 6, so that the accommodation space 88 formed by the opposed gripping grooves 86 thereon is smaller than the size of the gripping portion of the file. In operation, the pressing portion 92 of the releasing member 9 is pushed towards the neck 4, so that the elastic member 62 of the force applying mechanism 6 is compressed, the second clamping head 84 moves towards the direction far away from the first clamping head 82, the accommodating space 88 formed by the opposite clamping grooves 86 on the second clamping head is larger than the holding portion of the root canal file, then the holding portion of the root canal file is placed in the accommodating space 88, the pressing portion 92 of the releasing member 9 is loosened, and the elastic member 62 pushes the force applying member 64 to drive the connecting rod 66 to pull the second clamping head 84 to move towards the first clamping head 82, so that the holding portion of the root canal file is clamped. When the root canal file is removed, the pressing portion 92 of the releasing member 9 is pushed toward the neck portion 4, so that the elastic member 62 of the urging mechanism 6 is compressed, the second holding head 84 moves in a direction away from the first holding head 82, the holding force of the holding portion 8 is released, the accommodating space 88 formed by the opposing holding grooves 86 thereon is made larger than the size of the holding portion of the root canal file, and then the holding portion of the root canal file is taken out of the accommodating space 88.

The root canal file holder is specially designed for the common root canal file in clinic and is used for replacing the finger holding root canal file of a doctor, the holding is stable, the operability is good, and the root canal file can not rotate and swing after holding the root canal file; the neck is small, the root canal orifice can be observed by a doctor in a very large visual field, and the root canal file can be placed in the root canal more easily; simple with the root canal file separation, the thumb promotes on the stalk portion and presses the splenium can separate with the root canal file, can let the dentist continue to use finger centre gripping root canal file to carry out the unobstructed of root canal after the root canal file finds the root canal mouth, accomplishes medical procedure's seamless linking. The utility model is suitable for a various root canal files are used always to clinical, needn't form a complete set special root canal file, and clinical practicality is extensive, still can be used to beginner's simple root canal entry study, also can be used to the microscopical root canal under the orificial exploration, unobstructed.

To sum up, the utility model discloses root canal file holder simple structure, the centre gripping is stable, and convenient operation does benefit to the treatment, extensive applicability.

From the above, it is obvious to those skilled in the art that various other changes and modifications can be made according to the technical solution and the technical idea of the present invention, and all such changes and modifications should fall within the protection scope of the claims of the present invention.
