The present invention adds a jacking device on the basis of the IC base body 20, as shown in fig. 4 and 5, the jacking device includes an upper baffle plate 1, a left square block 2, a right square block 3, a left positioning round bar 4, a right positioning round bar 5, a left wedge 6 and a right wedge 8, which are connected together to form a whole, and the whole can only move up and down in a vertical direction relative to the IC base body 20.
Principle that the jack-up device can only move up and down in the vertical direction with respect to the IC base body 20: as shown in fig. 8, a left cross bar 10 and a right cross bar 11 are installed between two opposite side walls of the IC base body 20, a left round hole 12 and a right round hole 15 are respectively provided on the left cross bar 10 and the right cross bar 11, which longitudinally penetrate, the left positioning round bar 4 is inserted into the left round hole 12, and meanwhile, the right positioning round bar 5 is inserted into the right round hole 15, so that the left positioning round bar 4 and the right positioning round bar 5 can move freely up and down, and the left cross bar 10 and the right cross bar 11 are fixed on the IC base body 20, so that the left positioning round bar 4 and the right positioning round bar 5 can only move freely up and down and cannot move left and right.
The left rod 7 and the right rod 9 are mutually independent from the jacking device, the cross sections of the left rod 7 and the right rod 9 are square, one end of the left rod 7 and one end of the right rod 9 are planes, and the other end of the left rod 7 and the other end of the right rod 9 are inclined planes; the left bar 7 and the right bar 9 can move only horizontally with respect to the IC base body 20.
Principle that the left bar 7 and the right bar 9 can move only left and right in the horizontal direction with respect to the IC base body 20: as shown in fig. 8, a left cross bar 10 and a right cross bar 11 are installed between two opposite side walls of the IC base body 20, a left hole 13 and a right hole 14 which are transversely penetrated are respectively arranged on the left cross bar 10 and the right cross bar 11, and a left rod 7 and a right rod 9 are respectively inserted into the left hole 13 and the right hole 14 and can move freely left and right, as shown in fig. 9, the square rods cannot rotate and can only move freely left and right because of the square rods and the square holes, which can ensure that the inclined planes of the left rod 7 and the right rod 9 are exactly parallel and opposite to the inclined planes of the left wedge 6 and the right wedge 8.
As shown in fig. 6, the inclined surfaces of the left square rod 7 and the left wedge 6 are exactly parallel and opposite, when the left square rod 7 moves horizontally and rightwards, the inclined surface of the right end of the left square rod 7 slides together with the inclined surface of the left wedge 6 to generate a force upwards right for the left wedge 6, and because the jacking device is as a whole and can only move up and down along the vertical direction all the time, when the left square rod 7 moves horizontally and rightwards, the final resultant force of the left wedge 6 is upwards, namely the resultant force born by the jacking device is upwards vertically, so as to move upwards. Since the left square 2 and the right square 3 are close to the bottom of the integrated circuit IC chip 21 at first, the integrated circuit IC chip 21 is lifted up and stressed uniformly in the process of moving up the left square 2 and the right square 3, so that the integrated circuit IC chip 21 is pulled out from the IC base body 20 safely.
Similarly, when the right rod 9 moves horizontally and leftwards, a vertical and upward resultant force is finally given to the right oblique wedge 8, so that the left square block 2 and the right square block 3 move upwards and jack up the integrated circuit IC chip 21, and the integrated circuit IC chip 21 is safely pulled out from the IC base body 20.
To ensure safety, the IC mount 20 is forced to be balanced when the left and right levers 7 and 9 are simultaneously pressed with force.
As is clear from the above analysis, when the left bar 7 and the right bar 9 are pressed toward the middle by a finger, the IC chip 21 is safely sprung by the left block 2 and the right block 3, and the IC chip 21 can be removed at this time, as shown in fig. 13. When the chip is taken away, the fingers are released, and the jack-up device is required to automatically return to the original position (i.e. reset), so that the left square block 2 and the right square block 3 are in high consistency with the upper surface of the IC base body 20, and the integrated circuit IC chip is convenient to install next time. The left positioning piece 18 and the right positioning piece 19 and the left spring 16 and the right spring 17 are respectively arranged at the lower ends of the left positioning round rod 4 and the right positioning round rod 5. As shown in fig. 10, the left positioning piece 18 and the right positioning piece 19 are respectively fixed at the lower ends of the left positioning round rod 4 and the right positioning round rod 5, the left spring 16 and the right spring 17 are respectively sleeved at the lower ends of the left positioning round rod 4 and the right positioning round rod 5, and the lower ends of the left spring 16 and the right spring 17 are fixedly connected with the left positioning piece 18 and the right positioning piece 19. The upper ends of the left spring 16 and the right spring 17 are fixed to the lower portions of the left rail 10 and the right rail 11, respectively. When the left bar 7 and the right bar 9 are pressed towards the middle by finger force, the integrated circuit IC chip 21 is sprung up safely by the left square block 2 and the right square block 3, the left spring 16 and the right spring 17 are in a compressed state at the moment, and after the hand is released, the jacking device automatically returns to the original position (returns to the original position) under the action of the elastic force of the left spring 16 and the right spring 17.
The invention uses two fingers to lightly press the left rod 7 and the right rod 9, the integrated circuit IC chip 21 can be safely pulled out from the tube seat, and the jacking device can automatically reset after the hands are loosened.
The foregoing is only a preferred embodiment of the invention, it being noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the invention.
