The plate 3 is a T-shaped structure, and a connecting cavity 7 is provided inside the connecting plate 3. A locking plate 6 is slidably connected in the connecting cavity 7. A positioning reminder device 9 is provided at the top of the locking plate 6. The positioning reminder device 9 is composed of a positioning plate 91, a positioning groove 92, a pressure sensing module 93, a connecting spring 94 and a traction rod 95. The tail end of the locking plate 6 is inserted in the middle of the positioning block 1. Two locking and fixing mechanisms 15 are provided in the middle of the positioning block 1. The two locking and fixing mechanisms 15 are located on both sides of the locking plate 6. The locking and fixing mechanisms 15 are composed of a rotating plate 151, a locking head 152, a blocking plate 153 and a spring shaft 154. A sliding plate 12 is provided at the side end of the locking and fixing mechanism 15. A reminder light 5 is fixedly connected to the side end of the connecting plate 3, and the reminder light 5 is electrically connected to the pressure sensing module 93.

[0027] The upper end of the mounting groove 16 is an inclined structure, which is convenient for snapping the headrest fixing foot 4 into the mounting groove 16. The bottom of the mounting groove 16 is an arc-shaped structure. The blocking block 221 is located in the middle part of the mounting groove 16. When the headrest fixing foot 4 is inserted into the mounting groove 16, the lower end of the blocking block 221 rests on the headrest fixing foot 4. After the headrest fixing foot 4 is installed in the mounting groove 16, the blocking block 221 blocks the headrest fixing foot 4 and limits the vertical direction of the headrest fixing foot 4.

[0028] The extrusion plate 17 is an L-shaped structure, and a guide groove 20 is provided at the side end of the extrusion plate 17. The blocking block 221 is slidably connected to the guide groove 20. A second return spring 18 is fixedly connected between the extrusion plate 17 and the inner wall of the sliding groove 19.

The deformation piece 225 has a zigzag structure, and the positioning protrusion 226 is fixedly connected to the lower end of the deformation piece 225. When the headrest fixing foot 4 and the positioning block 1 are installed, the headrest fixing foot 4 squeezes the guide slope, thereby pushing the blocking block 221 and the squeezing plate 17 to move together. The squeezing plate 17 squeezes the sliding plate 12 when moving, and at the same time, the squeezing plate 17 compresses and accumulates force on the connecting spring 94. When the headrest fixing foot 4 moves to the lower end of the blocking block 221, the blocking block 221 is reset under the action of the connecting spring 94.

[0029] The side end of the positioning protrusion 226 is an arc-shaped structure. When the headrest fixing foot 4 is inserted into the installation groove 16, the clamping groove 10 is opposite to the blocking block 221, and the positioning protrusion 226 is clamped in the clamping groove 10. The adjustment groove 227 is located at the side end of the blocking block 221. The bottom of the adjusting groove 227 is provided with a thread. The side end of the extrusion plate 17 is provided with an adjusting screw 21. One end of the adjusting screw 21 is rotatably connected to the extrusion plate 17. The other end of the adjusting screw 21 is provided with a straight groove. The side end of the extrusion plate 17 is provided with a groove. The main body of the adjusting screw 21 is located in the groove. The side end of the adjusting screw 21 is threadedly connected to the adjusting groove 227. The headrest fixing foot 4 When the blocking block is at the lower end, pull the headrest fixing foot 4 again to make the side end of the headrest fixing foot 4 and the positioning plate 91 abut against each other. At this time, if the positioning protrusion 226 is not engaged with the engaging groove 10, rotate the adjusting screw 21, and the adjusting screw 21 drives the blocking block 221 to move, thereby fine-tuning the position of the blocking block 221 to move the positioning protrusion 226 to the engaging groove 10. The positioning protrusion 226 is engaged in the engaging groove 10 under the action of the deformation piece 225, thereby horizontally positioning and fixing the headrest fixing foot 4 to avoid movement of the headrest fixing foot 4 and the headrest frame during welding, thereby ensuring the quality of welding.

[0030] Both ends of the connecting plate 3 are provided with positioning plates 91, and both ends of the connecting spring 94 are fixedly connected to the two positioning plates 91 respectively. The positioning plate 91 is slidably connected in the connecting cavity 7. The positioning groove 92 is located at the side end of the positioning plate 91. The positioning groove 92 is a V-shaped structure. The pressure sensing module 93 is located at the bottom of the positioning groove 92. Both sides of the locking plate 6 are fixedly connected with side plates 8. The locking plate 6 and the two side plates 8 form a cross-shaped structure. The side plate 8 is slidably connected to the inner wall of the connecting cavity 7. The top of the locking plate 6 is hinged with two traction rods 95. The two traction rods 95 are respectively hinged with the two positioning plates 91. Before the headrest fixing foot 4 is installed with the positioning block 1, the positioning plate 91 is retracted inside the connecting plate 3 to avoid interference with the installation of the headrest fixing foot 4. After the headrest fixing foot 4 is installed, the squeezing plate 17 squeezes the sliding plate 12 to make the positioning plate 91 pop out of the connecting plate 3. When the headrest fixing foot 4 is pulled, the headrest fixing foot 4 is snapped into the positioning groove 92, thereby positioning the distance between the side end of the headrest fixing foot 4 and the positioning block 1, so as to facilitate the fine-tuning of the positioning protrusion 226 to snap into the snapping groove 10.

[0031] A spring shaft 154 is fixedly connected to the middle of the positioning block 1, and a rotating plate 151 is provided in the middle of the spring shaft 154. The locking head 152 and the blocking plate 153 are respectively fixedly connected to the two ends of the rotating plate 151. Locking grooves 11 are provided on both sides of the locking plate 6. Before the headrest fixing foot 4 is installed with the positioning block 1, the locking head 152 and the locking groove 11 are clamped, and the top of the sliding plate 12 is an inclined structure. A first return spring 13 is fixedly connected between the tail end of the sliding plate 12 and the positioning block 1. The side end of the sliding plate 12 is fixedly connected with an extrusion protrusion 14, and the extrusion protrusion 14 abuts against the side end of the rotating plate 151. When the sliding plate 12 is squeezed, the sliding plate 12 drives the extrusion protrusion 14 to move together, and the extrusion protrusion 14 squeezes the rotating plate 151, thereby moving the locking head 152 out of the locking groove 11, and under the action of the connecting spring 94, the two positioning plates 91 pop out of the connecting plate 3.

[0032] When the headrest fixing foot 4 moves to the bottom of the blocking block 221, the blocking block 221 is reset to position the headrest fixing foot 4 in the vertical direction, and the squeezing plate 17 squeezes the sliding plate 12 when moving, so that the positioning plate 91 pops out of the connecting plate 3. At this time, the headrest fixing foot 4 is pulled, and the headrest fixing foot 4 is clamped into the positioning groove 92, and the positioning protrusion 226 is clamped into the clamping groove 10. If the positioning protrusion 226 is not clamped into the clamping groove 10, the adjusting screw 21 is rotated, and the adjusting screw 21 drives the blocking block 221 to move, and the positions of the blocking block 221 and the positioning protrusion 226 are fine-tuned to ensure that the headrest fixing foot 4 is positioned and fixed in the horizontal direction.
