when the L-shaped rod 12 is pressed by a worker during working, one end, close to the fixture block 51, of the L-shaped rod 12 extrudes the fixture block 51, one end, close to the fixture block 51, of the L-shaped rod 12 is in the shape of a circular arc, sliding friction force between the L-shaped rod 12 and the surface of the fixture block 51 is reduced, the fixture block 51 is more easily retracted into the first groove 5 by pressing the L-shaped rod 12, the situation that the worker cannot press the L-shaped rod 12 due to small force is avoided, meanwhile, the situation that the L-shaped rod 12 is broken due to the fact that the friction force between the L-shaped rod 12 and the surface of the fixture block 51 is too large, the force for pressing the L-shaped rod 12 is increased by the worker is avoided, the use effect of the L-shaped rod 12 pressing device is guaranteed, and the practicability of the L-shaped rod 51 pressing device is improved.
The specific working process is as follows:
when the clamping device is used, a worker slides one end of the shell 2 into the second groove 4, two ends, far away from each other, of the two clamping blocks 51 are in contact with the base 1, and along with the fact that the shell 2 continues to slide along the second groove 4, the two clamping blocks 51 are extruded by the base 1 into the first groove 5 and slide along the mutually approaching direction until the two clamping blocks 51 completely enter the first groove 5; along with the continuous movement of the shell 2, the shell 2 slides to the bottom of the second groove 4, at the moment, the two fixture blocks 51 stop contacting with the base 1, and the two fixture blocks 51 are separated from each other under the action of the first spring 52, so that the two separated ends of the two fixture blocks 51 are positioned in the corresponding third groove 11, at the moment, the fixture blocks 51 are clamped by the base 1, the shell 2 cannot slip from the second groove 4, and the pedestrian warning device for low-speed vehicle driving is more stably installed; the pedestrian warning device for low-speed running of the vehicle is prevented from being separated from the base 1, and the infrared distance measuring sensor in the pedestrian warning device for low-speed running of the vehicle is damaged along with shaking of the vehicle, so that the infrared distance measuring sensor in the pedestrian warning device for low-speed running of the vehicle cannot scan and measure the distance of the pedestrian normally, and the pedestrian in front of a driver cannot be reminded, and tragic conditions are caused; when a worker needs to take down the shell 2 to overhaul the pedestrian warning device during low-speed running of the vehicle, the two L-shaped rods 12 are pressed, so that the L-shaped rods 12 slide towards the direction close to the fixture blocks 51, the L-shaped rods 12 are in contact with the fixture blocks 51 and press the fixture blocks 51, the two fixture blocks 51 slide close to each other in the first groove 5 until the two fixture blocks 51 are retracted into the first groove 5, the worker pulls the shell 2 at the moment, the shell 2 slides along the second groove 4, two ends, far away from each other, of the two fixture blocks 51 abut against the groove wall of the second groove 4, and the worker stops pressing the L-shaped rods 12 and slides the L-shaped rods 12 at the moment, so that the L-shaped rods 12 return to the original positions; then, the worker continuously pulls the shell 2 until the shell 2 is pulled out of the second groove 4; the whole vehicle low-speed running pedestrian warning device is transversely arranged in an automobile, and the front plate 3 faces the automobile head, so that the vehicle low-speed running pedestrian warning device can conveniently scan pedestrians; in the prior art, the pedestrian warning indicator for low-speed running of the vehicle is arranged on the base 1 of the vehicle, the opening at the upper end is large, and the opening at the lower end is small; in an initial state, one end of the L-shaped rod 12 is not located in the second groove 4, a worker presses the L-shaped rod 12, the L-shaped rod 12 rotates to press the second-size spring 14, and meanwhile one end, close to the fixture block 51, of the L-shaped rod 12 presses the fixture block 51; after the worker releases the L-shaped rod 12, the second spring 14 pushes the L-shaped rod 12 to rotate in the opposite direction until the L-shaped rod 12 returns to the original position, and then the second spring 14 restores to the original state; when the shell 2 is close to the bottom of the second groove 4, the magnet 15 at the bottom of the second groove 4 generates suction to the bottom of the shell 2, and the magnet 15 sucks the shell 2 to the bottom of the second groove 4; when the automobile runs, the magnet 15 always attracts the shell 2, so that the fixing effect of the fixture block 51 on the shell 2 is enhanced, and the shell 2 is more stably connected with the base 1; a worker puts the shell 2 into the second groove 4, so that the first spring 52 pushes the two clamping blocks 51, the clamping blocks 51 abut against the inclined end face of the first block 18, the first block 18 moves upwards, the first block 18 pushes the second block 19 by means of the inclined face between the first block 18 and the second block 19, and the two second blocks 19 abut against the shell 2 and clamp the shell 2; the fixture block 51 continues to push the first block 18 until the first block 18 is positioned in the fourth groove 16, at the moment, the first block 18 is in contact with the end face of the fixture block 51, and the fixture block 51 supports the first block 18; when a worker presses the L-shaped rod 12, the fixture block 51 retracts into the first groove 5, so that the first block 18 slides downwards in the fourth groove 16 until the first block 18 is contacted with the L-shaped rod 12 and returns to the original position; the first block 18 is in contact with the L-shaped rod 12 in the initial state, so that the first block 18 is prevented from slipping from the fourth groove 16 in the initial state, the first block 18 cannot be pushed by the fixture block 51 when the shell 2 enters the second groove 4, the second block 19 cannot clamp the shell 2, and the practical application effect of the invention is ensured; the L-shaped rod 12 is pressed by an operator, one end of the L-shaped rod 12, which is close to the fixture block 51, extrudes the fixture block 51, the shape of the end of the L-shaped rod 12, which is close to the fixture block 51, is arc-shaped, so that the sliding friction force between the L-shaped rod 12 and the surface of the fixture block 51 is reduced, the fixture block 51 is more easily retracted into the first groove 5 by pressing the L-shaped rod 12, the situation that the L-shaped rod 12 is not moved when the operator presses the L-shaped rod 12 due to small strength is prevented, and the situation that the L-shaped rod 12 is broken due to the fact that the friction force between the L-shaped rod 12 and the surface of the fixture block 51 is too large when the operator increases the force for pressing the L-shaped rod 12 is prevented, the use effect of the invention is ensured, and the practicability of the invention is improved.
