Paddle main shaft 1 is for cutting off cylinder, and long 300mm diameter 7mm, cuts off cylinder and refer to longitudinally clip a part, truncated face width 5mm; At A end, be provided with stiff end 2, long 20mm diameter 9mm, is shaped as the cut off cylinder consistent with main shaft 1, truncated face width 5mm; Apart from A end be respectively 68,82,107,131mm place is provided with spacing hole 3, spacing hole 4, spacing hole 5, spacing hole 6; At B end, be provided with spindle chuck 7, the thick 3mm of diameter 11mm, card is provided with spindle chuck draw-in groove 8.
Sleeve 9 is cylinder, long 150mm internal diameter 7mm external diameter 9mm, and cylinder inner face is designed to the curved surface mating with paddle main shaft 1; Spacing button 10 consists of groove 14, back shaft 15, pressing plate 16, spring 17; The thick 3mm of muff chuck 11 diameter 13mm, card is provided with muff chuck draw-in groove 12.
Puddle support 13 is that two joints are hinged formation, and every joint is of a size of the thick 2mm of the wide 5mm of long 50mm, totally 6 of puddle supports 13.
beneficial effect
1, puddle support acts freely, and pulls sleeve that puddle support is closed up before putting into flask, and after putting into, lower pushing sleeve cylinder is to required gear, and puddle support has just launched.
2, it is adjustable that puddle support launches amplitude, carries out 4 grades of adjustings, thereby umbrella shape puddle support can be suitable for for 100ml, 250ml, 500ml, 1000ml flask by sleeve, spacing button and spacing hole, easy to use.
3, the beveled structure of puddle support, be easy to stir lower end material, be difficult for to produce splash, mixing effect is good.
4, paddle spindle design is for cutting off cylinder, and sleeve inner face is designed to the curved surface mating with paddle main shaft; This design makes sleeve stir on main shaft can only linear slide, can not rotate.
5, paddle main axis length and rugosity are reasonable in design, and the design of its stiff end is mated with the draw-in groove of electric mixer.
