[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 4 A paint sheet metal repair gun comprises a repair gun body 1, a connector 2 is installed at one end of the repair gun body 1, a square card slot 5 is provided inside the connector 2, a terminal 4 is inserted into the square card slot 5, a positioning component is provided between the terminal 4 and the connector 2, slots 11 are provided on both sides of the terminal 4, avoidance grooves 13 and round holes 12 are provided on both sides of the connector 2, and the round holes 12 are connected to the slots 11 and the avoidance grooves 13, an insertion rod 10 is inserted into the slots 11 and the round holes 12, and the outer side of the insertion rod 10 is sleeved There is a tension spring 14, and the tension spring 14 is located inside the avoidance groove 13. The avoidance groove 13 can avoid the tension spring 14. The two ends of the tension spring 14 are respectively fixed to the insertion rod 10 and the connector 2. The pull block 3 is pulled outward to move the insertion rod 10 out of the slot 11, and the tension spring 14 contracts. Then the end 4 is inserted into the square slot 5, so that the positioning assembly positions the end 4, and then the pull block 3 is released, the tension spring 14 rebounds and stretches, so that the insertion rod 10 is inserted into the slot 11, so that the end 4 is stably installed in the connector 2.

[0024] In the present invention, it should be noted that the positioning assembly includes two hemispherical card slots 9, which are respectively opened at the top and bottom of the end head 4, and the top inner wall and the bottom inner wall of the connector 2 are both provided with a slide groove 6, a slide plate 7 is slidably connected in the slide groove 6, a spring 17 is welded on the upper surface of the slide plate 7, and the spring 17 is fixed to the connector 2, and a hemispherical card block 8 is fixed to the bottom of the slide plate 7 by bolts. Through the cooperation of the slide plate 7 and the slide groove 6, the hemispherical card block 8 can be stably moved up and down, the hemispherical card block 8 is connected to the hemispherical card slot 9, the pull block 3 is pulled outward, the insertion rod 10 is moved out of the slot 11, and the tension spring 14 is contracted, and then the end head 4 is inserted into the square card slot 5, so that the end head 4 squeezes the hemispherical card block 8. Slot 9, at this time, the slide plate 7 moves upward along the slide slot 6, and the spring 17 contracts until the hemispherical slot 9 on the end head 4 corresponds to the position of the hemispherical block 8.
