[0013] Figure 2 Is Figure 1 The enlarged structure schematic diagram of M of DETAILED DESCRIPTION

[0014] The utility model is described in detail below in combination with the specific implementation mode:

[0015] As Figure 1 And Figure 2 The implant outer thread is screwed into the firmness detection device, which comprises a box body 1, a support column 2, a bottom plate 3, a middle plate 31, a top plate 32, a test sleeve 4, a telescopic bellows 5 and a test head 6, the first box door 11 is hingedly installed on the top of the box body 1, the air inlet pipe 14 and the exhaust pipe 15 are arranged on the both sides of the box body 1, four support columns 2 are fixedly installed on the box body 1 in a rectangular distribution, the bottom plate 3 and the top plate 32 are fixedly sleeved and installed on the lower end and the top end of the support column 2 respectively, the middle plate 31 is slidably sleeved and installed on the support column 2, the test head 6 is fixedly installed on the bottom plate 3 in a linear distribution, the middle plate 31 is provided with through holes 321 corresponding to the test head 6, the test sleeve 4 is coaxially arranged corresponding to the through holes 321, and the test sleeve 4 is screw-fixedly installed on the middle plate 31, the telescopic bellows 5 is sealingly and fixedly connected with the middle plate 31 and the bottom plate 3 at the upper end and the lower end respectively, and the telescopic bellows 5 is provided with an air pipe joint 300 at the lower end;

[0016] The test head 6 consists of an impact head 60, a T-shaped guide rod 61, a spring 62, a guide sleeve 63, and a platform 65. The platform 65 is fixedly mounted on the middle plate 31, and the guide sleeve 63 is fixedly mounted on the platform 65. A T-shaped hole 64 is provided inside the guide sleeve 63, and the T-shaped guide rod 61 is slidably mounted in the T-shaped guide hole 64. The impact head 60 is coaxial and fixedly mounted on the top end of the T-shaped guide rod 61, and the spring 62 is sleeved on the T-shaped guide rod 61. The upper and lower ends of the spring 62 act on the impact head 60 and the guide sleeve 63, respectively.

[0017] The box 1 is equipped with a water collection tank 7. The steam gas introduced into the box 1 condenses into water droplets and is collected through the water collection tank 7.

[0018] The right side of the housing 1 is hinged with a second door 12 that allows the water collection tank 7 to be removed. Opening the second door 12 facilitates the removal and placement of the water collection tank 7.

[0019] The box 1 includes a pad 13 fixedly installed on the inner wall of the box body 1 to support the first box door 11. After the first box door 11 is closed, it is placed on the pad 13, which can reduce the pressure on the hinge of the first box door 11 and extend the service life of the hinge.

[0020] Open the first box door 11, tighten the implant tooth 10 onto the test sleeve 4 using a tool, close the first box door 11, and introduce 40°C water vapor into the box 1 through the air inlet pipe 14. The water vapor is then circulated out through the exhaust pipe 15. The air pipe connector 300 is connected to an air pump with both filling and suction functions through a pipeline. When the air pump fills the telescopic corrugated pipe 5, it pushes the middle plate 31 upward. When the air pump draws air from the telescopic corrugated pipe 5, it pushes the middle plate 31 downward. The test head 6 moves up and down with the middle plate 31. After the impact head 60 contacts the implant tooth 10, it compresses the spring 62 of the impact head 60. The elastic force of the spring 62 squeezes the test head 6. After 350-450 pressure tests on the test head 6, open the first box door 11 and check the firmness of the test head 6 on the test sleeve 4.
