When the height of the mounting bracket needs to be adjusted to suit the installation requirements of the front bumper of different models of cars, the electric push rod 304 is started, and the electric push rod 304 begins to extend or shorten, pushing the adjustment frame 305 connected to its top to move up and down in the first slide groove 302 inside the support 301. The limit blocks 306 on both sides of the adjustment frame 305 move together with the adjustment frame 305. During the movement, the telescopic springs 308 in the telescopic holes 307 inside the limit blocks 306 are in a compressed or extended state. When the adjustment frame 305 moves to the appropriate height, the telescopic springs 308 push the limit plates 309 to move outward, so that the positioning blocks 310 on the outer end surface of the limit plates 309 are inserted into the positioning holes 311 at the corresponding positions on the inner wall surface of the limiting groove 303.

The symmetrical thread distribution ensures that the slider is evenly stressed during movement and will not deviate to one side, thereby improving the stability and accuracy of movement. The outer wall size of the slider 406 is consistent with the inner wall size of the first slide groove 302, thereby ensuring the stability of the slider 406 during movement and will not shake or get stuck. At the same time, the tight fit also makes the movement of the slider 406 more precise, and can accurately move the clamping device to the desired position, thereby improving the efficiency and accuracy of installation.

[0028] Working principle: First, when the front bumper of the car needs to be installed, the multiple sets of universal wheels 2 at the bottom of the base frame 1 are first used to move the installation bracket to the appropriate position. The multiple sets of universal wheels 2 are symmetrically arranged, which can evenly share the weight of the bracket, ensure a smooth movement process, prevent tilting or shaking due to unstable center of gravity, protect other components on the bracket and the bumper being installed, and improve operational safety. Then, according to the bumper installation requirements of different models, the height positioning mechanism 3 is started to adjust the height. The electric push rod 304 pushes the adjustment frame 305 to move up and down in the first slide groove 302 inside the support 301, and the limit blocks 306 on both sides of the adjustment frame 305 are level in the limit groove 303. 303, and the screw threaded rod 404 rotates. 4 threaded connection, under the rotation of the threaded rod 404, the slider 406 moves along the second slide groove 402 on the fixed rod 401 to adjust the clamping position. When the slider 406 moves to the appropriate position, the cylinder 409 is started, and the cylinder 409 pushes the push rod 410 to move downward, so that the first transmission ratchet 412 at the bottom of the push rod 410 descends and engages with the second transmission ratchet 413. The second transmission ratchet 413 is connected to the housing 411 through the rotating shaft 414 and rotates under the push of the first transmission ratchet 412. The clamping plate 418 is driven to rotate inward through the coupling 417 to clamp the front bumper of the car. The anti-slip grooves 419 on the surface of the clamping plate 418 increase the protection The friction between the bumpers ensures firm clamping. During the clamping process, the auxiliary part 416 on the fixed shaft 415 plays a role in auxiliary support and stabilizing the rotation of the second transmission ratchet 413. Through the coordinated action of the height positioning mechanism 3 and the mobile clamping mechanism 4, the mounting bracket can accurately adjust the position and firmly clamp the front bumper of the car, improve the installation efficiency and accuracy, and adapt to the installation requirements of different models.
