DETAILED DESCRIPTION

[0029] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction to the technical solution of the present invention.

[0030] like Figure 1-5 As shown, as a limiting tool for processing an automobile headrest of the present invention, it includes a U-shaped fixing plate 40, a connecting column 50, a locking sleeve 60 and a clamping piece 70. The connecting columns 50 are symmetrically penetrated on both sides of the U-shaped fixing plate 40. The connecting columns 50 and the U-shaped fixing plate 40 are locked and limited by the locking sleeve 60. The bottom of the connecting column 50 is rotatably connected to the clamping piece 70.

[0031] The clamping member 70 includes a fixing seat 71, a first adjusting bolt 72 and an arc-shaped clamping block 73. A plurality of first adjusting bolts 72 are evenly arranged on the fixing seat 71. An arc-shaped clamping block 73 is fixed to the bottom end of the first adjusting bolt 72. The arc-shaped clamping block 73 is adjusted in position by the first adjusting bolt 72.

[0032] Specifically, the automobile headrest to be processed is placed between the two clamping members 70, and the user rotates the first adjusting bolt 72 to adjust the distance between the arc-shaped clamping block 73 and the fixing seat 71 by rotating the first adjusting bolt 72, so that the automobile headrest is clamped and limited on both sides by the arc-shaped clamping block 73. Through this structural setting, the automobile headrest with a curved surface can be clamped and limited, and the limiting effect of the automobile headrest is better, so that the subsequent related processing operations on the automobile headrest are convenient; in addition, through this structural setting, the automobile headrest can still be clamped and limited by the clamping member 70 after being rotated to different angles, so that its use effect is better;

[0033] Connecting columns 50 are symmetrically provided on both sides of the U-shaped fixing plate 40, and the connecting columns 50 and the U-shaped fixing plate 40 are locked and limited by a locking sleeve 60. Through this structural setting, the distance between the fixing seat 71 and the U-shaped fixing plate 40 can be adjusted, so that it is suitable for clamping operations of car headrests of different sizes, making it more applicable.

[0034] Example 1

[0035] like Figure 2-3 As shown, the connecting column 50 and the fixing seat 71 are connected by rotating the connecting sleeve 51 , and the fixing seat 71 rotates in the horizontal direction. The fixing seat 71 rotates to adjust the position of the first adjusting bolt 72 relative to the U-shaped fixing plate 40 .

[0036] Through this structural setting, the fixing seat 71 can be rotated relative to the U-shaped fixing plate 40, so that the position of the arc-shaped clamping block 73 on the fixing seat 71 relative to the car headrest can be adjusted, thereby being suitable for more different types of car headrest clamping operations, further improving its scope of application, and achieving better actual application effects.

[0037] Example 2

[0038] like Figure 4-5 As shown, the connection column 50 and the fixing seat 71 rotate by rotating the connection shaft 501 , and the fixing seat 71 rotates in the vertical direction. The fixing seat 71 rotates to adjust the position of the first adjusting bolt 72 relative to the U-shaped fixing plate 40 .

[0039] Through this structural setting, the fixing seat 71 can be rotated relative to the U-shaped fixing plate 40, so that the fixing seat 71 can be rotated to different inclination angles, and can be clamped for automobile headrests of different shapes, especially for some special-shaped automobile headrests, thereby further improving its scope of application.

[0040] like Figure 2 and Figure 4 As shown, the U-shaped fixing plate 40 is provided with an angle adjusting member 80 for adjusting the angle of the fixing seat 71. The angle adjusting member 80 includes a second adjusting bolt 81, a rotating card 82 and an extending rod 83. The second adjusting bolt 81 is passed through the U-shaped fixing plate 40. The bottom of the second adjusting bolt 81 is rotatably connected to one end of the extending rod 83 through the rotating card 82, and the other end of the extending rod 83 is fixed to the side wall of the fixing seat 71.

[0041] Specifically, when the user rotates the second adjusting bolt 81, the fixing seat 71 can be driven to rotate relative to the rotating connecting shaft 501, thereby adjusting the angle of the fixing seat 71. When the angle of the fixing seat 71 is adjusted, the first adjusting bolt 72 rotates, driving the arc-shaped clamping block 73 to move accordingly, thereby clamping the car headrest. Through this structural setting, the position of the clamped car headrest can be made more stable, and no shaking phenomenon will occur, and the actual application effect is better.

[0042] like Figure 6 As shown, a concave-convex layer is arranged on the arc surface of the arc clamping block 73. Through the arrangement of the concave-convex layer, when the arc clamping block 73 clamps the automobile headrest, the friction between the automobile headrest and the arc clamping block 73 is greater, and the position restriction of the automobile headrest is more stable. The right angle of the arc clamping block 73 is greater than the diameter of the first adjusting bolt 72, which can increase the contact area with the automobile headrest, and the placement position of the automobile headrest is more stable.

[0043] like Figure 7 As shown, a fixing ring 74 is sleeved on the first adjusting bolt 72 above the arc-shaped clamping block 73, and a connecting spring 75 is provided between the fixing ring 74 and the fixing seat 71. Through the setting of the fixing ring 74, the space between the fixing ring 74 and the fixing seat 71 can be used to clamp some car headrests that need to be clamped at corners, which can be applicable to more different types of car headrests, thereby further improving its scope of application.

[0044] like Figure 8As shown, a resistance rod 76 is fixed at the bottom of the fixing seat 71, and the resistance rod 76 is located in the space between the first adjusting bolt 72 and the connecting spring 75. At least three resistance rods 76 are arranged and are distributed at equal angles above the fixing ring 74. The diameter of the fixing ring 74 is equal to the diameter of the arc-shaped clamping block 73. By setting the resistance rod 76, the minimum distance between the fixing ring 74 and the fixing seat 71 can be limited, thereby determining the maximum distance between the fixing ring 74 and the arc-shaped clamping block 73, so as to perform a clamping operation on a car headrest of suitable thickness.

[0045] An arc-shaped notch 41 is provided on the inner wall of the U-shaped fixing plate 40, and the spacing between the arc-shaped notches 41 is greater than the spacing between the two fixing seats 71. Through this structural setting, there is enough space for the placed car headrest to be placed, avoiding the U-shaped fixing plate 40 affecting the position of the car headrest, and the actual application effect is better.

[0046] like Figure 8 As shown, the U-shaped fixing plate 40 is connected to the support column 20 through the locking block 30. The support column 20 and the U-shaped fixing plate 40 are vertically arranged. A fixed base 10 is fixed at the bottom of the support column 20. The user can choose a support column 20 of a suitable height according to actual conditions, thereby facilitating the clamping operation of the car headrest and achieving better actual application effects.

[0047] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
