A spring rod 53 is connected between the slide plate 52 and the inner wall of the mounting groove 11. A touch plate 54 is fixedly connected to the slide plate 52, and a gear 55 is rotatably connected in the touch plate 54. A rack 56 is slidably connected to the side wall of the touch plate 54, and the rack 56 slides through the outer wall of the touch plate 54. The rack 56 slides through the outer wall of the touch plate 54. One end of 56 located outside the mounting groove 11 is fixedly connected to the fixing head 5, and a straight rod 57 is fixedly connected in the mounting groove, and the straight rod 57 slides through the slide plate 52 and the touch plate 54, and one end of the straight rod 57 located inside the touch plate 54 is fixedly connected to the rack 2 58. The rack 1 56 and the rack 2 58 are matched and meshed with the gear 55. When the control arm needs to be clamped and fixed, the open threaded hole of the control arm is aligned with the mounting groove 11 and inserted. The open threaded hole squeezes the slide plate 52 to make it move. The slide plate 52 squeezes the spring rod 53 and drives the touch plate 54 to move accordingly. In this process, Figure 3As shown, the straight rod 57 drives the gear 55 to rotate through the rack 2 58, and the gear 55 drives the fixed head 59 to move outward through the rack 1 56. The surface of the fixed head 59 is equipped with an anti-slip structure, so that the two fixed heads 59 clamp and fix the open threaded hole of the control arm;

[0024] A moving assembly 4 for controlling the sliding of the two fixed rods 2 is installed on the base 1 , and a limiting assembly 7 for limiting the rotation of the fixed assembly 5 is installed on the circular plate 6 .

[0025] The moving component 4 includes a protrusion 41, and a slide rail 42 is provided on the base 1. The protrusion 41 is fixedly connected to the slide rail 42. Springs 43 are symmetrically connected to both ends of the protrusion 41. The ends of the two springs 43 are fixedly connected to a slider 44. The two sliders 44 are respectively fixedly connected to the bottom ends of the two fixed rods 2. The initial state of the device is that the two fixed rods 2 are located in the center. When the device is used, the two fixed rods 2 are moved to both sides. During this process, the two springs 43 change from a normal state to a stretched state, and the control arm is placed in the fixed component 5. Subsequently, the two fixed rods 2 move toward the center under the elastic force of the two springs 43, so that the open threaded hole of the control arm squeezes the slide 52 to trigger the fixed component 5 to complete the fixing process.

[0026] The limiting assembly 7 includes a turntable 71, which is fixedly connected to the side wall of one of the mounting plates 51. A toothed disc 72 is fixedly mounted on the turntable 71. A second slide groove 73 is opened on the circular plate 6. A second slider 74 is slidably connected in the second slide groove 73. The side wall of the second slider 74 is fixedly connected with a latch 76. The position of the latch 76 matches the position of the toothed disc 72. A telescopic rod 8 is fixedly connected between the two mounting plates 51. In the initial state of the limiting assembly, the latch 76 engages with the toothed disc 72 to limit the rotation of the toothed disc 72. When the control arm needs to be rotated after clamping When adjusting the rotation, first pull the connecting plate 75 upward, and the connecting plate 75 drives the locking tooth 76 to move upward through the cooperation of the second slide groove 73 and the second slider 74, thereby canceling the locking fixation of the locking tooth 76 on the toothed disc 72. At this time, the turntable 71 is rotated, and the turntable 71 drives the mounting plate 51 to rotate through the cooperation of the slide groove 1 9 and the swivel 10, and the mounting plate 51 on the other side drives the mounting plate 51 to rotate synchronously through the telescopic rod 8, thereby realizing the rotation adjustment of the control arm. After the adjustment is completed, the limit assembly 7 is reset, thereby realizing the adjustment and fixation of the control arm angle.

[0027] A pulling plate 3 is fixedly connected to the side walls of the two fixing rods 2, and the pulling plate 3 can assist the stretching operation of the two fixing rods 2.

[0028] A knob 12 is fixedly connected to the turntable 71 , and the rotation of the turntable 71 can be easily controlled by the knob 12 .

[0029] The base 1 is provided with a plurality of screw holes 13 , which facilitate the installation and fixation of the base 1 .

[0030] In the present invention, when the device is used, the two fixing rods 2 are moved to both sides. During this process, the two springs 43 change from a normal state to a stretched state, and the control arm is placed in the fixing assembly 5. Subsequently, the two fixing rods 2 move toward the center under the elastic force of the two springs 43, so that the open threaded holes of the control arm are aligned with the mounting slots 11 and placed in. The open threaded holes squeeze the slide plate 52 to move it. The slide plate 52 squeezes the spring rod 53 and drives the touch plate 54 to move accordingly. In this process, Figure 3 As shown, the straight rod 57 drives the gear 55 to rotate through the rack 2 58, and the gear 55 drives the fixed head 59 to move outward through the rack 1 56. The fixed head 59 is equipped with an anti-slip structure on the surface, so that the two fixed heads 59 clamp and fix the open threaded holes of the control arm; when the control arm needs to be rotated and adjusted after being clamped, the connecting plate 75 is first pulled upward, and the connecting plate 75 drives the locking teeth 76 to move upward through the cooperation of the sliding groove 2 73 and the sliding block 2 74, thereby canceling the locking and fixing of the gear plate 72 by the locking teeth 76. At this time, the turntable 71 is rotated, and the turntable 71 drives the mounting plate 51 to rotate through the cooperation of the sliding groove 1 9 and the rotating ring 10, and the mounting plate 51 drives the mounting plate 51 on the other side to rotate synchronously through the telescopic rod 8, thereby realizing the rotation adjustment of the control arm. After the adjustment is completed, the limit assembly 7 is reset, thereby realizing the adjustment and fixation of the angle of the control arm.
