Next, the holding rod 9 is held by the hand, the holding rod 9 is pushed backwards to be far away from the body of a person, the holding rod 9 drives the rotating rod 4 to rotate in the horizontal direction, and the holding rod 9 swings a certain angle. The rotary rod 4 drives the rear shift rod 6 to move towards the direction approaching the traction seat 2 while rotating, and the shift claw 7 on the shift rod 6 is separated from the space between the original two shift teeth 12 and advances to the space between the other two shift teeth 12. At this time, the front shift lever 6 moves in the direction approaching the fixed seat 1 while rotating, and the shift claw 7 on the shift lever 6 is still positioned between the original two shift teeth 12, and hooks the shift teeth 12 to drive the shift teeth 12 to move towards the fixed seat 1 together. The pulling teeth 12 drive the traction rod 11 to move towards the fixed seat 1, the traction rod 11 drives the second fixing plate 10 to move towards the fixed seat 1, and finally the second fixing plate 10 drives the traction seat 2 to move towards the fixed seat 1 together with the longitudinal vertical plate 21. The whole process is that the poking rods 6 on two sides can be always close to each other due to the existence of the springs 8, and the poking claws 7 on two sides can always clamp the traction rod 11.

Next, the holding rod 9 is pushed forward to approach the body of the person, the holding rod 9 swings reversely by a certain angle, and at the moment, the poking claw 7 on the poking rod 6 at the rear side hooks the poking teeth 12, and finally the traction seat 2 is driven to move towards the fixed seat 1 together with the longitudinal vertical plate 21. While the finger 7 on the front finger 6 leaves between the original two teeth 12 and advances between the other two teeth 12. The fifth wheel 2 is then moved along with the longitudinal uprights 21 towards the fixed seat 1 continuously by pushing the grip lever 9 to swing repeatedly in the horizontal direction. Because the holding rod 9 is positioned above the fixed seat 1, and the swing of the holding rod 9 is carried out in the horizontal direction, the fixed seat 1 can not form an obstacle to the movement of the holding rod 9, the holding rod 9 can continuously swing, the whole traction process can not be interrupted, and the utility model not only saves time but also has high efficiency when used for traction.

Referring to fig. 3, a trapezoid notch 19 is disposed on a sidewall of the traction seat 2 facing the fixing seat 1, and a longitudinal width of a narrow opening end of the trapezoid notch 19 is greater than a longitudinal width of the fixing seat 1, so that when the traction seat 2 approaches the fixing seat 1, the traction seat 2 will not collide with the fixing seat 1, and the traction seat 2 will not form a blockage.

The groove 15 and the rib 16 cooperate to play a limiting role, when the traction seat 2 is continuously close to the fixing seat 1, the traction rod 11 continuously passes through the through hole 14, the rib 16 slides along the inner wall of the groove 15, at the moment, the traction rod 11 can only move left and right and can not move up and down or back and forth, and the stability in the traction process is ensured. The longitudinal width of the through hole 14 is larger than the longitudinal width between the poking teeth 12 at the two sides of the traction rod 11, so that when the traction rod 11 continuously passes through the through hole 14, the poking teeth 12 cannot collide with the first fixing plate 3, friction force cannot be generated, and the service life of the poking teeth 12 can be prolonged.

Working principle: when the utility model is used, an operator clamps the notch of the fixing seat 1 into the right end of the upper part of the transverse vertical plate 20, so that the fixing seat 1 is firmly fixed on the transverse vertical plate 20. And simultaneously, the notch of the traction seat 2 is clamped into the upper part of the longitudinal vertical plate 21, so that the traction seat 2 is firmly fixed on the longitudinal vertical plate 21. Next, the holding rod 9 is held by the hand, the holding rod 9 is pushed backwards to be far away from the body of a person, the holding rod 9 drives the rotating rod 4 to rotate in the horizontal direction, and the holding rod 9 swings a certain angle. The rotary rod 4 drives the rear shift rod 6 to move towards the direction approaching the traction seat 2 while rotating, and the shift claw 7 on the shift rod 6 is separated from the space between the original two shift teeth 12 and advances to the space between the other two shift teeth 12. At this time, the front shift lever 6 moves in the direction approaching the fixed seat 1 while rotating, and the shift claw 7 on the shift lever 6 is still positioned between the original two shift teeth 12, and hooks the shift teeth 12 to drive the shift teeth 12 to move towards the fixed seat 1 together. The pulling teeth 12 drive the traction rod 11 to move towards the fixed seat 1, the traction rod 11 drives the second fixing plate 10 to move towards the fixed seat 1, and finally the second fixing plate 10 drives the traction seat 2 to move towards the fixed seat 1 together with the longitudinal vertical plate 21. Next, the holding rod 9 is pushed forward to approach the body of the person, the holding rod 9 swings reversely by a certain angle, and at the moment, the poking claw 7 on the poking rod 6 at the rear side hooks the poking teeth 12, and finally the traction seat 2 is driven to move towards the fixed seat 1 together with the longitudinal vertical plate 21. While the finger 7 on the front finger 6 leaves between the original two teeth 12 and advances between the other two teeth 12. The fifth wheel 2 is then moved along with the longitudinal uprights 21 towards the fixed seat 1 continuously by pushing the grip lever 9 to swing repeatedly in the horizontal direction. When the gap between the transverse riser 20 and the longitudinal riser 21 is closed to a suitable width, the operator can start the welding operation.
