[0032] according to Figure 1-9 A hand root canal file clamping handle shown in the figure comprises a handle body 1 and a clamp 2 for clamping and fixing a hand root canal file 3, wherein the clamp 2 is fixedly arranged at the top of the handle body 1, and the clamp 2 comprises a chuck body 21, a lower clamp block 22, an upper clamp block 23, an adjustment pad 24 and a fastening screw 25;

[0033] The chuck body 21 is fixedly arranged at the top of the handle body 1, and an upper clamping block fixing groove 4 is opened on the top end surface of the chuck body 21, and the upper clamping block 23 is movably installed inside the upper clamping block fixing groove 4;

[0034] A curved hook body 5 is integrally provided at the top of the upper clamping block 23, and a root canal file upper fixing groove 6 is provided on one side of the curved hook body 5 for fixing the hand root canal file 3;

[0035] A root canal file lower fixing groove 7 is provided at a position on the front end surface of the lower clamping block 22 corresponding to the root canal file upper fixing groove 6, and the root canal file is movably clamped between the root canal file upper fixing groove 6 and the root canal file lower fixing groove 7, and the root canal file upper fixing groove 6 and the root canal file lower fixing groove 7 are matched with the two side walls of the root canal file respectively;

[0036] The lower clamp block 22 is arranged at the top of the clamp body 21, and a through hole 8 is formed inside the lower clamp block 22. The upper clamp block 23 passes through the through hole 8 and is movably connected to the lower clamp block 22.

The upper clamp block 23 is threadedly connected to the upper clamp block fixing groove 4.

[0040] The specific implementation method is as follows: before using the hand-held root canal file 3, the upper clamping block 23 is first passed through the through hole 8 on the lower clamping block 22, and then the fastening screw 25 is passed through the adjustment pad 24 and inserted into the fastening threaded hole 9, and the fastening screw 25 is rotated to make it cooperate with the fastening threaded hole 9 until one end of the fastening screw 25 is in contact with the outer wall of the upper clamping block 23. At this time, the fastening screw 25 is not rotated further, so that the upper clamping block 23 can move freely in the through hole 8 on the lower clamping block 22, and then the upper clamping block 23 is slightly pulled out of the through hole 8 for a distance, so that the root canal file upper fixing groove 6 on one side of the curved hook body 5 at its end and the root canal file lower fixing groove 7 on one side of the through hole 8 are separated from each other, and then the handle end of the hand-held root canal file 3 is inserted between the root canal file upper fixing groove 6 and the root canal file lower fixing groove 7, and then the upper clamping block 23 is pushed in the direction of the lower clamping block 22 so that the root canal file upper fixing groove 6 and the root canal file lower fixing groove 7 are aligned. The clamping screw 25 is then rotated to tighten the upper clamping block 23 and the lower clamping block 22, thereby clamping the handle end of the hand root canal file 3. The clamping screw 25 is then rotated to tighten the upper clamping block 23 and the lower clamping block 22. The clamping screw 25 is then rotated to tighten the upper clamping block 23 and the lower clamping block 22. The clamping screw 25 is then tightened ... block 2 and the lower clamping block 22 are then tightened to tighten the upper clamping block 2 and the lower clamping block 22. The clamping block 2 and the lower clamping block 22 are then tightened to tighten the upper clamping block 2 and the lower clamping block 22. The clamping block 2 and the lower clamping block 22 are then tightened to tighten the upper clamping block 2 and the lower clamping block 22. The clamping block 2 and the lower clamping block 22 are then tightened to tighten the upper clamping block 2 and the lower clamping block 22. The clamping block 2 and the lower clamping block 22 are then tightened to tighten the upper clamping block 2 and the lower clamping block 22.

[0041] like Figure 3 As shown, the handle body 1 is configured in a hexagonal column shape, the chuck body 21 is configured in a truncated cone shape, and the diameter decreases from one end away from the clamp 2 to the other end, and the chuck body 21 is integrally formed with the handle body 1;

[0042] The specific implementation method is as follows: the handle body 1 is designed in a hexagonal column shape, and the diameter decreases from one end to the other end, so that the doctor can pick it up without slipping, not easy to fall off, and easy to operate.

[0043] like Figure 5-6 As shown, a limiting groove 10 is provided on a side wall of the upper clamping block 23 close to the fastening screw 25, and one end of the fastening screw 25 passes through the fastening threaded hole 9 and extends to the inside of the limiting groove 10 to abut against the upper clamping block 23; the width of the limiting groove 10 is greater than the diameter of the bottom end of the fastening screw 25, and the bottom end of the fastening screw 25 cooperates with the limiting groove 10.

[0044] The specific implementation method is as follows: by providing a limiting groove 10 on the contact surface of the upper clamping block 23 and the fastening screw 25, when the upper clamping block 23 and the lower clamping block 22 are inserted and connected, the fastening screw 25 can be inserted into the limiting groove 10, and the upper clamping block 23 can be extended and retracted in the lower clamping block 22. After fixing the hand root canal file 3, the fastening screw 25 is rotated to make it support the limiting groove 10, so as to achieve the fixation between the upper clamping block 23 and the lower clamping block 22, and at this time, the upper clamping block 23 and the lower clamping block 22 cannot rotate relative to each other. Therefore, when the upper clamping block 23 is rotated again, the lower clamping block 22 and the hand root canal file 3 can be driven to rotate at the same time, so as to achieve the connection with the chuck body 21, that is, the connection and fixation with the handle body 1.

[0045] Working principle of the present invention:
