[0051] Optional, see Figure 3 As shown, the dental device in this embodiment further includes a screw cap 7, which includes a main body 71 screwed to the compression sleeve 6 and a rotating part 72 abutting against the compression sleeve 6, and the main body 71 is provided with a ring part 73 extending inwardly, and the ring part 73 abuts against the outer wall of the end of the metal heating tube 3 away from the push rod 4. According to this design, when the gutta-percha overflows from the end of the metal heating tube 3 away from the push rod 4, the screw cap 7 can be rotated to move the ring part 73 away from the push rod 4 to bring the overflowed gutta-percha out of the compression sleeve 6, so as to facilitate cleaning and maintenance of the dental device.

[0052] Optional, see Figure 2 , Figure 3 As shown, the metal heating tube 3 in this embodiment is provided with a flat portion 31, and the inner wall of the fixing cap 2 (ie, the inner wall of the second mounting portion 23) is provided with a limiting protrusion 231 that matches the flat portion 31. According to this design, the metal heating tube 3 can be prevented from rotating in the circumferential direction.

[0053] Optional, see Figure 4 , Figure 5As shown, the dental device in this embodiment also includes a clamping member 8 screwed into the fixing cap 2, the clamping member 8 is sleeved on the push rod 4 and abuts against the metal heating member, and the clamping member 8, the metal heating tube 3, and the push rod 4 enclose a receiving cavity, and the sealing member 5 is fixedly installed in the receiving cavity. A fixed cavity is formed between the outer wall of the end of the clamping member 8 away from the base 1 and the inner wall of the fixing cap 2, and the metal heating tube 3 can be partially fixedly installed in the fixed cavity, so when the clamping member 8 is screwed into the fixing cap 2, the metal heating tube 3 can be tightly fitted with the inner wall of the fixing cap 2 through the clamping member 8, so that it is fixedly installed in the fixing cap 2.

[0054] In order to facilitate pushing the push rod 4, refer to Figure 4 As shown, the dental device in this embodiment further includes a motor 9, and the motor 9 is partially fixedly installed in the second end of the base 1. The base 1 is provided with a third assembly hole 15 arranged in a radial direction, and the motor 9 is provided with a fourth assembly hole 91 matched with the third assembly hole 15. The motor 9 is fixedly installed in the second end of the base 1 through a third fixing member 103 that passes through the third assembly hole 15 and the fourth assembly hole 91. The third fixing member 103 can be any part such as a screw or a bolt for fastening the motor 9 and the base 1.

[0055] Preferably, an encoder is provided at the end of the motor 9 in this embodiment away from the base 1. The encoder can detect the number of revolutions of the motor 9, thereby knowing the rotation speed of the motor 9.

[0056] In addition, refer to Figure 5 As shown, the inner wall of the fixed cap 2 and the outer wall of the metal heating tube 3 in this embodiment enclose a temperature measuring cavity, and the dental device further comprises a temperature measuring block 300 fixedly installed in the temperature measuring cavity. The temperature measuring block 300 has two metal wires of different materials, which can form a thermocouple, and the temperature measuring block 300 is in contact with the metal heating tube 3, thereby achieving the technical effect of measuring the temperature of the metal heating tube 3.

[0057] Preferably, in order to prevent the fixing cap 2 from axially moving in the base body 1, refer to Figure 3 As shown, in this embodiment, a plurality of first protrusions 211 are arranged at intervals along the axial direction on the outer wall of the end portion (i.e., the first mounting portion 21) of the fixing cap 2 extending into the first end of the base 1, and the first protrusions 211 are arranged to extend in the radial direction (i.e., extend outwardly), and a first groove 13 is arranged on the inner wall of the base 1 to match the first protrusions 211. According to this design, when the first protrusions 211 and the first grooves 13 are matched, the axial movement of the fixing cap 2 in the base 1 can be limited.

[0058] It should be understood that, since the fixing cap 2 is installed inside the first end of the base 1 through the first fixing member 101 arranged along the axial direction of the base 1, the circumferential rotation of the fixing cap 2 can be naturally limited by the cooperation between the first fixing member 101 and the first assembly hole 11 and the second assembly hole 221. Therefore, the second protrusion 212 described in the second embodiment does not need to be provided on the first mounting portion 21, and the second groove 14 described in the second embodiment does not need to be provided on the base 1. Of course, when the second protrusion 212 is provided on the first mounting portion 21, the second groove 14 cooperating with the second protrusion 212 can also be provided on the base 1 (refer to Figure 3 shown).

[0059] Embodiment 2:

[0060] The difference from the embodiment is that: in order to sleeve the fixing cap 2 inside the base 1, refer to Figure 6 As shown, the clamping sleeve 6 and the base 1 in this embodiment enclose a mounting groove 61, the fixing portion 22 of the fixing cap 2 is fixedly installed in the mounting groove 61, and the first mounting portion 21 of the fixing cap 2 is sleeved in the first end of the base 1. Among them, the inner wall of the clamping sleeve 6 in this embodiment, which is close to the base 1, has a step extending inward, and the step and the end surface of the base 1 enclose a mounting groove 61. When the end of the fixing cap 2 (i.e., the first mounting portion 21) is sleeved inside the first end of the base 1, the fixing portion 22 of the fixing cap 2 is inserted into the mounting groove 61.

[0061] It should be understood that the fixing portion 22 of the fixing cap 2 in the present embodiment is inserted into the mounting groove 61, so the fixing portion 22 may rotate circumferentially in the mounting groove 61. Therefore, in order to avoid causing the fixing cap 2 to rotate circumferentially in the base 1, a plurality of second protrusions 212 are arranged at intervals along the circumferential direction on the end wall of the fixing portion 22 facing the base 1 in the present embodiment. The second protrusion 212 is arranged to extend axially along the base 1, and a second groove 14 is arranged on the end wall of the first end of the base 1 to cooperate with the second protrusion 212. The circumferential rotation of the fixing cap 2 can be limited by the cooperation between the second protrusion 212 and the second groove 14.

[0062] Embodiment three:

[0063] The difference from the first embodiment is that: in order to sleeve the fixing cap 2 inside the base 1, refer to Figure 7 As shown, in this embodiment, the fixing portion 22 of the fixing cap 2 is fixedly mounted to the base 1 through the first fixing member 101 , and the fixing portion 22 is inserted into the mounting groove 61 .

[0064] Embodiment 4:

According to this design, when the first protrusions 211 and the first grooves 13 match, the axial movement of the fixing cap 2 in the base 1 can be limited.

[0067] In addition, a mounting groove 16 for fixing and mounting the first mounting portion 21 is provided on the end wall of the first end of the base 1 in this embodiment, and a plurality of second protrusions 212 are provided at intervals along the circumferential direction on the end wall of the first mounting portion 21 fixedly mounted in the mounting groove 16, and the second protrusions 212 are provided to extend axially along the base 1, and a second groove 14 is provided on the bottom wall of the mounting groove 16 to match the second protrusions 212. The circumferential rotation of the fixing cap 2 can be limited by the cooperation between the second protrusions 212 and the second groove 14.
