[0017] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0018] Reference Figure 1-2As shown, a front cowl stay bushing with a stable structure comprises a sheet metal 1 and a bushing body 2 arranged above the sheet metal 1, the bushing body 2 mainly comprises a waist-shaped head 4, a barrel 5 fixed to the bottom surface of the head 4, and two triangular-shaped clamping blocks 9 symmetrically arranged on both sides of the outer wall of the barrel 5, a positioning hole 7 connected to the inner cavity of the barrel 5 is formed through the middle of the head 4, a limiting groove 6 matching the shape of the head 4 is formed on the top surface of the sheet metal 1, and a through groove 8 connected to the limiting groove 6 and corresponding to the barrel 5 is formed on the bottom surface of the sheet metal 1;

[0019] When installing the bushing body 2 on the sheet metal 1, the barrel 5 can be directly rotated and inserted into the through groove 8. During this process, the bevel of the clamping block 9 is pre-pressed to deform the barrel 5 and reduce the obstruction. When the clamping block 9 completely penetrates the sheet metal 1, the clamping block 9 abuts against the bottom surface of the sheet metal 1, and the head 4 is embedded in the inner side of the limiting groove 6. In this way, the limiting groove 6 cooperates with the clamping block 9 to effectively clamp the bushing body 2 on the sheet metal 1.

[0020] And through the setting of the limiting groove 6 and the waist-shaped head 4, when the bushing body 2 is clamped on the sheet metal 1, the waist-shaped head 4 can be embedded in the corresponding limiting groove 6, so that the two can cooperate to effectively limit the bushing body 2 and prevent the bushing body 2 from rotating when the support rod is rotated and lifted, causing wear.

[0021] However, from a practical point of view, the block 9 and the cylinder 5 in the prior art are formed as an integrated whole, which results in a fixed distance between the bottom end of the block 9 and the top surface of the head 4. Once there is a deviation between the thickness of the sheet metal 1 to be assembled with the bushing body 2 and the distance between the two, the block 9 will easily have a certain distance from the bottom surface of the sheet metal 1 after the head 4 is embedded in the limiting groove 6, thereby affecting the stability of the bushing body 2 when used in the sheet metal 1.

[0022] For this purpose, refer to Figure 2 As shown, it is worth noting that two movable grooves 10 are symmetrically provided on the wall of the cylinder 5, and two clamping blocks 9 are respectively slidably arranged in the two movable grooves 10, and a lifting component for adjusting the clamping blocks 9 up and down is arranged on the top of the head 4;

[0023] The lifting component includes a rotating sleeve 11 rotatably arranged on the top surface of the head 4 and a pull rope 12 fixed to the top of the clamping block 9. The end of the pull rope 12 is inserted into the rotating sleeve 11 and fixed with a connecting piece, and the connecting piece is vertically fixed to the inner wall of the rotating sleeve 11.

[0024] By setting the lifting component, a simple knob rotating sleeve 11 can make the rotating sleeve 11 pull the card block 9 by the pull rope 12 during the rotation process, so that the card block 9 can be lifted and lowered inside the movable groove 10, so as to facilitate manual and quick adjustment of the distance between the card block 9 and the head 4 according to the thickness of the sheet metal 1, thereby improving the application range of the device.

[0025] Further, refer to Figure 2 As shown, it is worth noting that a paddle 13 is vertically fixed to the outer wall of the rotating sleeve 11, and a paddle post 14 is fixed to the end of the paddle 13;

[0026] By setting the paddle 13 and the paddle post 14 , the rotating sleeve 11 can be conveniently controlled to rotate by paddle post 14 .

[0027] Further, refer to Figure 2 As shown, it is worth noting that the inner side of the lever 14 is threadedly connected with a screw rod 3, a plurality of positioning holes 7 are provided on the top surface of the head 4 along the arc, and a through groove corresponding to one of the positioning holes 7 is provided at the end of the lever 13, and the through groove is connected to the inside of the lever 14;

[0028] After the rotation sleeve 11 is gripped, the knob screw 3 is then turned to cause the screw 3 to penetrate into the inner side of the corresponding positioning hole 7 under the threaded structure. The positioning hole 7 cooperates with the screw 3 to effectively lock the rotation sleeve 11, so that the block 9 can remain stable after sliding inside the movable groove 10.
