Furthermore, both ends of the fixed seat 1 are provided with grooves 11, and a connecting seat 12 is arranged on the fixed seat 1 corresponding to the position of the movable part 32; the adjusting assembly is provided at one side of the coupling socket 12.

During operation, recess 11 that fixing base 1 both sides set up is favorable to the follow-up inseparable PCB board of taking out the block, and can fix the adjusting part on the connecting seat 12, before clamping PCB board, should utilize the interval between the rough adjustment movable part 32 of adjusting part and the fixed part 31 by the size of operating personnel according to PCB board.

Further, the adjusting assembly is composed of a threaded rod 21, a bearing 22 and a ball nut 23; one end of the threaded rod 21 is fixedly connected to the movable part 32, and the other end of the threaded rod 21 penetrates through the connecting seat 12; the bearing 22 is fixedly connected to one side of the connecting seat 12, and the ball nut 23 is movably connected in the bearing 22; the other end of the threaded rod 21 is screwed into a ball nut 23.

During operation, when the operator adjusts the distance between the fixed portion 31 and the movable portion 32, the ball nut 23 is rotated first, so that the threaded rods 21 on both sides can rotate with the corresponding threads of the ball nut 23, and because the ball nut 23 rotates on the bearing 22, when the ball nut 23 is rotated manually, the threaded rods 21 on both sides can horizontally slide in the connecting seat 12, and the connecting relationship between the connecting block 325 on the movable portion 32 and the connecting groove 312 on the fixed portion 31 is matched, so that the distance between the movable portion 32 and the fixed portion 31 can be adjusted.
