When the torque spring is placed in the U-shaped groove 21, the torsion arm of the torque spring can be inserted into the V-shaped groove 24. A handle 25 with the same height as the axis of the U-shaped groove 21 is also fixedly provided between the U-shaped groove 21 and the first slide rail 5. When the operator installs the torque spring, he can hold the handle with four fingers and press the torque spring into the U-shaped groove 21 with his thumb to facilitate installation. A pressing device 10 is arranged above the V-shaped groove 24, and the pressing device 10 is installed on the first track 5. The pressing device 10 includes a pressing plate 101 arranged above the V-shaped groove 24 and extending vertically downward, and a first handle 102 connected to the pressing plate 101. The first handle 102 is hingedly installed on the first track. When the first handle 102 is pressed from top to bottom, the bottom of the pressing plate 101 can be at the same height as the top plate of the U-shaped groove 21. When the first handle 102 is pressed, the pressing plate 101 can be driven to press the torsion arm of the torque spring downward to form a displacement deformation of 5°, 10°, 15°, 20°, etc. with the horizontal plane, which can make the inner diameter of the torque spring larger, and it is easier to pass through the inner cavity of the torque spring when installing the latch. At the same time, after the installation is completed, under the action of the pressing plate 101, the torque spring can be more easily separated from the U-shaped groove 21 and assembled on the car door handle.
