Bar portion and the shank being connected with bar portion, this when, bar portion are typically metal material, and shank is by being plastics, and human hand has
Sufficiently large frictional force, it is easy to operation
Further, the second described tup be provided with can with it is some or all of parcel the first tup shell, outside this when
Shell plays certain position-limiting action, and contiguous block coordinates the deviation for preventing the first tup and the second tup position.
In the present invention, the various metal materials that hypophysis can be commonly used, but in order to improve the mechanical property of metal and resistance to
Oxidisability, the present invention utilizes titanium alloy metal material, but existing titanium alloy inoxidizability is insufficient, essentially consists in titanium alloy gold
It is more to belong to impurity element, such as oxygen, and wearability deficiency, in order to solve the above problems, the present invention discloses a kind of conjunction of titanium
Golden material, for described titanium alloy by the way of vacuum fusion, the mode of wherein vacuum fusion is as follows：、
Step 1: from titanium material, it is put into smelting furnace；
Step 2: turning on the power, being passed through argon gas, holding vacuum is 15Kpa-40Kpa, is heated to 1700 DEG C of -1800 DEG C of progress
Melting, appropriate adjustment power is changed according to melt and make it that bubble is stable；
Step 3: when not having bubble formation, argon gas is passed through, holding vacuum is 50 Kpa -100 Kpa, is now added
Alloying element, described alloy is relative to 100 parts of titaniums, specially 0.001-0.05 parts lithium, 0.01-0.05 parts zinc, 0.001-
0.05 part of chromium, 0.001-0.05 parts lanthanum and 0.001-0.05 part ceriums.Wherein add alloy element according to lithium, chromium, lanthanum, cerium it is suitable
Profit, the volatilization that can so reduce alloying element are lost in.
Used Step 4: cooled down after 10min-50min is melted and in bottom by nitrogen gas stirring, when cooling
Ultrasonic irradiation crystallizes, and ultrasonic power is M* (20-150) W, and M is molten alloy quality, wherein can be with by ultrasonic irradiation
Improve titanium alloy crystal grain compactness so that heat resistance, intensity are greatly improved, wherein experiment finds that being passed through nitrogen can fill
Divide stirring, make crystalline material more uniform.
Step 5: ingot casting, post processing processing.
