Furthermore, a column head is arranged at the top end of the positioning column, the column head is sunken inwards in the lower direction to form a neck groove used for clamping a lead, when the lead of the loudspeaker is pulled out and clamped into the clamping groove of the conductive pin of the loudspeaker, the lead is clamped into the neck groove and is tightly pressed by the positioning column to pre-tighten the lead, so that an operator does not need to specially reserve a section of lead to realize movable allowance, and the simplicity and convenience of operation are greatly improved.

Furthermore, a fixed shaft is arranged on the bottom surface of the jig body, and the rotating block is mounted on the fixed shaft through a bearing to form a rotatable structure, so that the rotating block can easily rotate.

Furthermore, positioning strips are respectively arranged on the periphery of the upper surface of the jig body, a positioning space for placing the loudspeaker is defined by the positioning strips, and the positioning space can be matched with the bottom edge of the loudspeaker, so that the loudspeaker can be accurately positioned after being placed in the positioning space.

Furthermore, a positioning shaft is arranged in the positioning hole, and after the loudspeaker is arranged on the jig, the positioning shaft is inserted into the magnetic return of the loudspeaker, so that the loudspeaker can be positioned more accurately and placed more stably.

Furthermore, the rotating holes are arc-shaped strip-shaped holes, the two rotating holes are surrounded on the peripheries of the two sides of the positioning hole, and the rotating holes face the conductive pins of the horn. Before the loudspeaker is installed in the jig, the two positioning columns are respectively positioned at the head ends of the rotating holes where the two positioning columns are respectively positioned. At the moment, the horn is arranged in the jig, the positioning columns are farthest away from the conducting wire, then the rotating block is rotated, and the two positioning columns respectively move along the rotating holes in which the positioning columns are located until the tail ends of the rotating holes. At the moment, the positioning column can clamp the lead through the neck groove of the positioning column, and after the lead is pulled to be clamped into the clamping groove of the conductive pin, the lead is clamped by the positioning column to form a tight bending state. After the welding of the conducting wire and the conducting pin is completed, the rotating block is rotated again, the positioning column returns to the original position, so that the clamping of the conducting wire is released, the conducting wire is loosened and has certain movement allowance, and the phenomena of breakage, loosening and the like caused by vibration or other reasons are avoided.

The utility model discloses mainly design to loudspeaker welding wire's demand, it can be stably conveniently fixed and location loudspeaker, more importantly can come the top tightly and loosen the wire through the removal of reference column for the wire is tightened completely when the assembly welding, then can relax after welding and prevent to tighten too tightly and fracture or pine take off, can realize through this tool that the wire obtains above-mentioned state very conveniently, operation process is very simple light, maneuverability is very good, practical convenient.
