[0016] Figure 1 It is a structural schematic diagram of the utility model.
[0017] As attached Figure 1 As shown, a handheld welding gun with adjustable gun head comprises a welding gun body 1 and a welding gun barrel 2. One end of the welding gun barrel 2 is rotatably connected to the welding gun body 1. A transmission mechanism 3 and a drive mechanism 4 are installed in the welding gun body 1. A front grip 5 is detachably installed at the bottom of the end of the welding gun body 1, and a rear grip 6 is rotatably connected to the welding gun body 1.
[0018] The transmission mechanism 3 includes a main gear 31 and an auxiliary gear 32 . The main gear 31 is fixed on the welding gun barrel 2 . Two auxiliary gears 32 are rotatably connected in the welding gun body 1 . The main gear 31 is located between the two auxiliary gears 32 . The main gear 31 meshes with the auxiliary gears 32 .
[0019] The driving mechanism 4 includes a motor 41 and a gear 42 . The gear 42 is fixed to the output shaft of the motor 41 , and the gear 42 is meshed with an auxiliary gear 32 .
[0020] The tail end of the rear grip 6 is rotatably connected to the welding gun body 1 through an axis, and a torsion spring is connected between the tail end of the rear grip 6 and the welding gun body 1 .
[0021] The top of the rear grip 6 is provided with an arc-shaped male head 7, and a connecting female head 8 for matching the arc-shaped male head 7 is slidably connected to the welding gun body 1, and a spring is connected between the welding gun body 1 and the connecting female head 8. When the arc-shaped male head 7 swings toward the connecting female head 8, it will push the connecting female head 8 to slide inward, and the spring is compressed at this time. When the end of the arc-shaped male head 7 moves to the front of the groove of the connecting female head 8, the connecting female head 8 will move outward under the drive of the spring rebound, so that the end of the arc-shaped male head 7 moves into the groove of the connecting female head 8.
[0022] The welding gun body 1 is provided with a receiving groove 9 for receiving the rear grip 6 .
[0023] A screw is provided on the top of the front grip 5 , and a screw hole is provided on the bottom of the end of the welding gun body 1 . The front grip 5 is threadedly connected to the welding gun body 1 through the screw.
[0024] The rear grip 6 and the front grip 5 are both wrapped with a silicone layer.
[0025] The use of the present application is as follows: when the welding gun barrel 2 is to be rotated, the motor 41 is started, the motor 41 drives the gear 42 to rotate, the gear 42 drives the auxiliary gear 32 to rotate, and the auxiliary gear 32 drives the main gear 31 and the welding gun barrel 2 to rotate, so that the muzzle direction can be adjusted without rotating the welding gun body 1. When it is to be used in a narrow space, the front grip 5 can be unscrewed from the screw hole of the welding gun body 1, and then the rear grip 6 can be swung into the accommodating groove 9 until the arc-shaped male head 7 is inserted into the connecting female head 8, thereby positioning the rear grip 6 in the accommodating groove 9.
