[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The present invention provides a material delivery device for tooth filling, such as Figure 1-5 As shown, it includes a cylinder 1, a plunger 2 arranged inside the cylinder 1, and a discharge pipe head 3 arranged at the end of the cylinder 1, a guide plate 5 is fixedly connected to the cylinder 1, and the length direction of the guide plate 5 is parallel to the axial direction of the cylinder 1, and a handle 4 is slidably fitted on the guide plate 5, a plurality of first positioning holes 6 are provided on the cylinder 1, a positioning plate 7 is fixedly connected to the handle 4, a second positioning hole 8 is provided on the positioning plate 7, and the first positioning hole 6 and the second positioning hole 8 correspond to each other, and a fixing component for fixing the positioning plate 7 and the guide plate 5 to each other is provided on the handle 4.

[0025] When the position of the handle 4 needs to be adjusted, the knob 12 is turned, and the knob 12 drives the stud 14 to rotate through the connecting rod 11. The rotation of the stud 14 causes the stud 14 to move back and forth in the screw hole 13, and the stud 14 drives the insertion rod 10 to withdraw from the first positioning hole 6 and the second positioning hole 8. At this time, the restriction of the insertion rod 10 is lost, so that the handle 4 can slide along the guide plate 5. After adjusting to the appropriate position, the knob 12 is turned in the opposite direction to reinsert the insertion rod 10 into the first positioning hole 6 and the second positioning hole 8, thereby completing the fixation of the position of the handle 4. It can be adaptively adjusted according to the user's own situation, making the operation feel more comfortable and easy to use.

[0026] The discharge pipe head 3 is bent.

[0027] The first positioning holes 6 are arranged at equal intervals, and the distance between two adjacent first positioning holes 6 is not less than the length of the positioning plate 7 .

[0028] The fixing assembly includes an insert rod 10, a stud 14, a connecting rod 11, a knob 12, a screw hole 13, and a fixing block 9. The fixing block 9 is fixedly connected to the handle 4. A screw hole 13 is provided in the fixing block 9. The stud 14 is threadedly engaged in the screw hole 13. The side of the stud 14 facing the positioning plate 7 is fixedly connected to the insert rod 10, the side of the stud 14 away from the insert rod 10 is fixedly connected to the connecting rod 11, and the end of the connecting rod 11 away from the stud 14 is fixedly connected to the knob 12. The insert rod 10 corresponds to the first positioning hole 6 and the second positioning hole 8.

[0029] The knob 12 is provided with anti-slip grooves.

[0030] Two guide plates 5 are provided, and the two guide plates 5 are symmetrically arranged on both sides of the cylinder 1 .

[0031] Working principle: When the position of the handle 4 needs to be adjusted, turn the knob 12, and the knob 12 drives the stud 14 to rotate through the connecting rod 11. The rotation of the stud 14 causes the stud 14 to move back and forth in the screw hole 13, and the stud 14 drives the insertion rod 10 to withdraw from the first positioning hole 6 and the second positioning hole 8. At this time, the restriction of the insertion rod 10 is lost, so that the handle 4 can slide along the guide plate 5. After adjusting to the appropriate position, turn the knob 12 in the opposite direction to reinsert the insertion rod 10 into the first positioning hole 6 and the second positioning hole 8, thereby completing the fixation of the position of the handle 4, so that it can be adaptively adjusted according to the user's own situation, making the operation feel more comfortable and easy to use.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
