[0025] It also includes a second fixing component for fixing the door handle, the second fixing component includes a first fixing plate 5 and a second fixing plate 6 which are symmetrically arranged, the first fixing plate 5 and the second fixing plate 6 are made of rubber material, a mounting plate 10 is fixedly installed on the top and bottom of the first fixing plate 5 and the second fixing plate 6, the mounting plate 10 is fixedly connected by bolts, the mounting plate 10 is made of stainless steel material, by making the first fixing plate 5 and the second fixing plate 6 of rubber material, the door handle can be fixed, and the wear on the door handle can be reduced, and the mounting plate 10 and the bolts are used to facilitate disassembly.

[0026] The pull assembly for pulling the door handle is also included, and the pull assembly includes a pull rod 7, one end of the pull rod 7 is fixedly connected to the first fixing ring 8, and the first fixing ring 8 and the second fixing ring 9 are rotatably matched. By setting the first fixing ring 8 and the second fixing ring 9, it is convenient for the pull rod 7 to pull the second fixing assembly and the door handle, and the two are rotatably matched, which is convenient for the operator to install the second fixing assembly; the second fixing ring 9 is fixedly installed on one side of the first fixing plate 5, the pull rod 7 and the directional sleeve 11 are slidably matched, and the limiting strips 12 are fixedly installed on both sides of the pull rod 7. The limiting grooves 13 are provided on both sides of the inner wall of the directional sleeve 11, and the limiting strips 12 and the limiting grooves 13 are slidably matched. The directional sleeve 11 passes through the center of the fixing frame 4, and the directional sleeve 11 is fixedly connected to the fixing frame 4. By setting the directional sleeve 11, the angle of the movement direction of the pull rod 7 is fixed, so that the pull rod 7 The door handle can be pulled vertically, thereby reducing wear between components and increasing service life. In conjunction with the limit strip 12 and the limit groove 13, the pull rod 7 can be prevented from rotating, thereby ensuring that the position of the pull plate 15 will not rotate, so that the toggle rod 14 can normally pull the pull plate 15; the pulling assembly also includes a toggle rod 14, which is fixedly mounted on one side of the surface of the turntable 16. The toggle rod 14 is used in conjunction with the pull plate 15, and the pull plate 15 is fixedly mounted on the other end of the pull rod 7. The center of one side of the turntable 16 is matched with the output end of the motor 17 for transmission. The motor 17 is fixedly connected to the fixed frame 4. By setting the turntable 16, the toggle rod 14 can be driven to pull and release the pull plate 15 and the pull rod 7 in a cyclical manner. The structure is simple and the cost is low. At the same time, the door handle can be repeatedly pulled to achieve the purpose of testing the durability of the door handle.

[0027] When in use, the device is moved to a designated position, the mounting base 2 and the suction cup 1 are rotated to adjust the angle of the suction cup 1 so that it fits around the door handle, and the suction cup 1 is fixed on the door by suction, the first fixing plate 5 is fitted on the outer surface of the door handle, and the second fixing plate 6 is fitted on the inner surface of the door handle, the bolt is passed through the mounting plate 10, and is tightened and fixed with an external tool. When the test starts, the motor 17 is started, and the output end of the motor 17 drives the turntable 16 to rotate counterclockwise, and at the same time drives the toggle rod 14 to start rotating around the center of the turntable 16. When the toggle rod 14 rotates downward from the left side of the turntable 16 to the designated position, the toggle rod 14 will contact the pull plate 15 and drive the pull plate 15 to rotate. Move to the left, the pull plate 15 pulls the pull rod 7, and the pull rod 7 pulls the door handle outward through the first fixing ring 8, the second fixing ring 9 and the second fixing assembly. When the toggle rod 14 rotates to the right side of the turntable 16, it starts to move upward. When it reaches a certain position, the toggle rod 14 and the pull plate 15 fall off. The pull plate 15, the pull rod 7 and other structures that have lost the pulling force are pulled to the left by the door handle and return to the initial position. As the turntable 16 continues to rotate at any time, when the toggle rod 14 moves to the left again, the pull plate 15 and the pull plate 15 continue to move to the right, and the door handle is pulled next time. The output end of the control motor 17 drives the turntable 16 to rotate continuously to repeatedly pull the door handle, thereby achieving the purpose of testing its fatigue performance.
