Especially, the positioning projection 20 is formed between the first fixing holes 22.
The second end 12 of the first holding bar 2 is formed a first recess 24 and a positioning notch 28. The positioning notch 28 penetrates the first outer surface 16 and connects the first recess 24. The first holding bar 2 defines a first through hole 28 penetrating the first inner surface 14 and the first outer surface 16 and between engaging portion 18 and the first recess 24. Especially, the first through hole 28 is close to the first recess 24.
The second holding bar 4 has a third end 30, a fourth end 32, a second inner surface 34 and a second outer surface 36 opposite to the second inner surface 34. The third end 30 of the second holding bar 4 is formed a positioning groove 38 on the second inner surface 34 and a pair of second fixing holes 40. The positioning groove 38 is mated with the positioning projection 22 of the first holding bar 2 and formed between the second fixing holes 40. The second fixing holes 40 penetrate the second inner surface 34 and the second outer surface 36, and aligned with the first fixing holes 22 of the first holding bar 2.

The lens module 80 is received in the receiving space 54. The pressing pieces 921 are urged to be apart from the lens module 80 by the outer surface of the clutching end 58 of the clutching jig 100. The clutching jig 100 is applied an external force from the first outer surface 16 and second outer surface 36 to urge the first holding bar 2 and the second holding bar 4 to move to each other. Hence, both the distances of the gap 52 and the receiving space 54, which are positioned between the first holding bar 2 and the second holding bar 4, will be narrowed.
Thus, if the lens module 80 is gripped in the receiving space 54, then the clutching end 58 and the lens module 80 gripped in receiving space 54 will be pulled from the lens socket 90. The first holding bar 2 and the second holding bar 4 are urged to return the original position via the coil spring 50 presses the restricting pins 48 and release of the external force. Hence, the lens module 80 is released from the receiving space 54 of the clutching jig 100.
As describe above, the clutching jig 100 is composed of first holding bar, the second holding bar, the fixing means and the elastic means, which are manufactured individually to avoid line cut procedure. Hence, it is easy to manufacture the clutching jig 100. And, it is convenient to fabricate the clutching jig 100. Each of components of the clutching jig 100 can be replaced partly in case the components are damaged, without replacing whole the clutching jig 100 for decreasing the cost.
