specific Embodiment 2

[0028] Specific embodiment 2: Step 1. The aluminum powder and titanium powder are processed for impurity removal and oxygen removal in a vacuum melting furnace, and a small amount of dilute elements are added during the vacuum melting process. The dilute elements are based on the mass of aluminum as 100 parts. The mass part of the element is 0.05 parts, of which the scattered element gallium,

[0029] Step 2: Mix 100 parts of aluminum powder and 8 parts of titanium powder according to parts by mass;

[0030] Step 3. Heat the mixture after step 2 in a vacuum furnace, keep it at 700°C-800°C for 20 minutes, then continue to heat up to 1400°C-1600°C for 30 minutes, pass nitrogen through the furnace, and follow 20 minutes after passing nitrogen. The temperature is lowered every minute until it drops to 700°C-800°C, and keep it at 1 H -2H;

[0031] Step four, the mixture after step three is subjected to ultrasonic radiation ingot casting, the power of ultrasonic radiation is 80*m W, where...

Description

Technical field [0001] The invention relates to the field of medical equipment. Background technique [0002] Dental splints are used to separate two adjacent teeth by a certain distance. The traditional way of dividing teeth is to open the retaining ring with pliers, and then place the retaining ring between the two teeth. After loosening the pliers, the two elastic arms of the retaining ring After resetting, the insert plates on the two elastic arms are inserted between the two teeth to separate the adjacent two teeth by a certain gap, and then the forming piece and wedges are put into the filling process. [0003] Such as figure 2 Shown is the conventional structure diagram of the existing dental clip, which is mainly controlled by a push rod threaded knob to control the opening and closing of the dental clip. This method causes the operator to be very close to the teeth during operation. , Block the light and affect the actual situation of the tooth operation part. Summary of...
