[0022] The following is combined with Figure 1 - Figure 4 This application is described in further detail.

[0023] The present application embodiment discloses a dental crown clamp that saves labor in operation. Figure 1 , Figure 2 , Figure 3As shown, it includes a first clamp handle 1 and a second clamp handle 2. The first clamp handle 1 and the second clamp handle 2 are each provided with an elastic steel sheet 12 on one side close to each other. A fixing groove 13 is opened inside one of the elastic steel sheets 12. A T-block 14 is fixedly connected to the outer surface of the other elastic steel sheet 12. The outer surface of the T-block 14 is slidably connected to the fixing groove 13. The first clamp handle 1 and the second clamp handle 2 serve as two handles of this crown clamp. The two elastic steel sheets 12 have resilience. By inserting the T-block 14 of one of the elastic steel sheets 12 into the fixing groove 13 in the other elastic steel sheet 12, during the squeezing process of the first clamp handle 1 and the second clamp handle 2, the two elastic steel sheets 12 will contact and compress, and push the corresponding first clamp handle 1 and the second clamp handle 2 to reset without the action of external force.

The inner wall of the second connecting block 4 is slidably connected to two plug blocks 7, and the outer surface of each plug block 7 is fixedly connected to a slider 8, and the outer surface of each slider 8 is slidably connected to the corresponding sliding groove 5. Through the setting of the sliding groove 5, the plug block 7 will be limited by the sliding groove 5 during the vertical sliding process in the second connecting block 4.

[0026] See also Figure 3 , Figure 4 A first thread groove 9 is provided at one end of the two plug blocks 7 away from each other, and second screws 10 are provided on the upper and lower sides of the second clamp handle 2. The outer surface of each second screw 10 is plugged into the corresponding first connecting block 3, and the outer surface of each second screw 10 is threadedly connected to the corresponding first thread groove 9. The plug block 7 can be quickly connected to the corresponding first connecting block 3 by connecting the second screw 10 to the corresponding first thread groove 9.

The ends of the two springs 6 that are away from each other are fixedly connected to the corresponding plug blocks 7, and the other ends are fixedly connected to the second connecting block 4. In the process of quickly connecting the first clamp handle 1 and the second clamp handle 2, the two plug blocks 7 are first pressed to make them slide vertically into the second connecting block 4. At this time, the slider 8 will slide vertically along the corresponding slide groove 5, the spring 6 begins to compress, and then the first clamp handle 1 and the second clamp handle 2 are connected, and then the first connecting block 3 and the second connecting block 4 are pushed to the same central axis, and then the spring 6 will push the corresponding plug block 7 to reset under the action of its rebound force.

[0031] The implementation principle of the tooth crown clamp of the embodiment of the present application is as follows: first, press the two plug blocks 7 to make them slide vertically into the second connecting block 4. At this time, the slider 8 will slide vertically along the corresponding slide groove 5, and the spring 6 will begin to compress. Then, the first connecting block 3 and the second connecting block 4 will be pushed to the same central axis. Then, the spring 6 will push the corresponding plug block 7 to reset under the action of its rebound force, and thereby push the corresponding plug block 7 to enter the corresponding slot 11, so as to complete the quick fixation of the first clamp handle 1 and the second clamp handle 2, and then use the second screw 10 to connect with the corresponding first threaded groove 9. Then, to increase the stability of the plug block 7, the fixing plate 22 is inserted along the corresponding placement groove 18 until the first socket 16 and the corresponding second socket 19 are on the same central axis, and then the fixing column 20 is inserted along the corresponding second socket 19 and passed through the corresponding first socket 16. At this time, the corresponding fixing column 20 is quickly fixed using the third screw 21 to complete the rapid disassembly and assembly of the pliers head 17, and then the elastic steel sheet 12 is fixed using the first screw 15. Through the cooperation of the two elastic steel sheets 12, the first pliers handle 1 and the second pliers handle 2 will be reset under the action of their rebound force when they are pressed.
