The invention discloses a scarf joint method of Canarium album ReauschsRaeusch. The method sequentially comprises the following steps of: selecting stock trees, selecting scions, carrying out scarf joint, fixing, managing after scarf joint, and managing the grafted trees which are subjected with to scarf joint for a long term. The scarf joint method of the Canarium album Reaaeuschs has the following advantages of: 1, improving the survival rate, wherein the survival rate of the grafted trees is improved to above 90% from the current 30-50%; 2, realizing dwarfing, wherein the height of the fruit-bearing trees are is descended to below 5 meters from 10 meters; 3, realizing close planting, wherein the plantings at every mu are increased to 30 plants from 12 plants; 4, realizing early bearing, wherein the trial period after planting is decreased to 4 years from 7 years, and the startup time is decreased to 6 years from 10 years; 5, realizing high yield, wherein the yield is improved to 1500 kilograms, but the traditional planting yield per mu is 600 kilograms; and 6, realizing high quality, wherein, comparing with seedling cultivation, a fine variety generation is cultivated through scarf joint with unseparated properties, and fine variety performance can be kept.

The invention discloses a crimping radio frequency coaxial connector, belonging to the radio frequency coaxial connectors. Aiming at the problems that the similar connector is complex in operation and sometime falls off when in use, the adopted technical scheme is as follows: the crimping end of a connecting sleeve is designed into a tubular crimping head with a larger external diameter of the neck and a smaller external diameter of the head, wherein the tubular crimping head is provided with steps and integrated with the connecting sleeve body into a whole; a welding operation window is designed at the neck of the tubular crimping head of the connecting sleeve; a ring-shaped bulge the cross section of which is in a wedge tooth shape is designed on a scarf joint insulation sleeve of the cavity in the connecting sleeve; a ring-shaped bulge the cross section of which is in a wedge tooth shape is designed on the scarf joint insulation sleeve on the periphery of an inner conductor; a ring-shaped bulge the surface of which is provided with axial horizontal streaks is arranged on the scarf joint insulation sleeve of the periphery of the inner conductor; and the tubular welding end of the inner conductor is designed into a semi-tubular inclined opening. After the coaxial connector is on trial, we can find that the number of the components is reduced to 4 from 6; the crimping working procedures are reduced to 5 from 12; the falling-off condition does not occur in using; the electric property is improved; and the voltage standing wave ratio is reduced to 1.15/3GHz from 1.25/3GHz.

The invention relates to a jack with the function of selecting needle, comprising a planar laminar basal; wherein, a scarf joint for connecting with knitting needle is arranged at the front of the basal; a front needle butt and a back needle butt for triangle pushing are arranged on the top of the basal.
