In figure：Handle 1, support 2, the first limited block 3, sleeve 4, the second limited block 5, force application rod 6, pin pulling head 7, thread segment
8th, alignment pin 9, workpiece 10, spanner 11, drive screw 12, push rod 13, top cap 14.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
Embodiment 1：
As shown in Figure 1-2, a kind of novel portable taking out positioning pin device, it includes support 2, passed through on the support 2
Screw thread, which coordinates, is provided with sleeve 4, and one end of the sleeve 4 is installed with handle 1, the sliding fit inside peace of the sleeve 4
Equipped with force application rod 6, the side end of the force application rod 6 is fixed with the first limited block 3, and it is another to be located at sleeve 4 on the force application rod 6
End is installed with the second limited block 5, and the other end of the force application rod 6 is installed with pin pulling head by being detachably threadedly coupled
7, the other end of the pin pulling head 7 is threaded section 8, and the corresponding threaded holes of the thread segment 8 and alignment pin 9 close.It is worked
By rotational handle 1 in journey, by handle 1 with moving sleeve 4, the mobile limit with force application rod 6 under screw-driven effect of sleeve 4
Position block is engaged, and drives pin pulling head 7 to extract pin-and-hole and then by alignment pin 9 by force application rod 6.
Embodiment 2：
Further, coordinated on the support 2 by screw thread and drive screw 12, the end of the drive screw 12 are installed
Spanner 11 is installed, the other end of the drive screw 12 is provided with push rod 13, and the front end of the push rod 13 sets crown cap 14,
