By providing the lubrication mechanism 3, after installing the graphite 306 on one side of the positioning frame 302, one end of the graphite 306 contacts the ball head body 4, so that the ball head body 4 can be lubricated. And by using the reaction force of the return spring 307 to drive the positioning frame 302 to move, the graphite 306 can continuously lubricate the ball head body 4, thereby reducing the maintenance efficiency of the staff.

[0028] Refer to Figure 3 and Figure 4 , two return springs 307 are provided on one side of the positioning frame 302. One end of the return spring 307 is fixedly connected to the inner wall of the positioning shell 301, and the other end of the return spring 307 is fixedly connected to the surface of the positioning frame 302.

The sealing ring 7 is sleeved on the outer side of the nut 2, and the inner side of the sealing ring 7 contacts the surface of the positioning shell 301. By providing the sealing ring 7, the connection between the positioning shell 301 and the nut 2 can be sealed and positioned, improving the safety of the use of the positioning shell 301.

[0031] Refer to Figure 5 , a slide rod 310 is slidably connected to the inner cavity of the clamping block 304. One end of the slide rod 310 is fixedly connected to the inner wall of the positioning frame 302. By providing the slide rod 310, the clamping block 304 can be limited, thereby improving the stability of the vertical movement of the clamping block 304.

[0032] Reference Figure 4 and Figure 5 , a clamping groove 311 is formed in the inner cavity of the graphite 306, and the clamping groove 311 is used in cooperation with the clamping block 304; by providing the cooperation of the clamping groove 311 and the clamping block 304, the graphite 306 can be positioned, thus facilitating the replacement of the graphite 306 by the staff.

[0033] Reference Figure 2 , a rubber ball seat 8 is fixedly installed in the inner cavity of the ball head seat 1, and the inner side of the rubber ball seat 8 is in contact with the surface of the ball head body 4; by providing the rubber ball seat 8, the ball head body 4 can be limited, thus improving the stability of the use of the ball head body 4.

[0034] Working principle: During use, the staff presses two pressure rods 303 towards each other. When the two pressure rods 303 move towards each other, they drive the two clamping blocks 304 to move towards each other. When the two clamping blocks 304 move towards each other, they squeeze the two first springs 305. When the two clamping blocks 304 move towards each other to a specified position, the staff inserts the graphite 306 into the inner cavity of the positioning shell 301 and aligns it with one side of the positioning frame 302. At this time, after the clamping block 304 is inserted into the inner cavity of the clamping groove 311, the staff releases the pressure rod 303, and uses the reaction force of the first spring 305 to drive the two clamping blocks 304 to move in the reverse direction, so that the clamping block 304 is clamped into the inner cavity of the clamping groove 311, and the fixation of the graphite 306 can be completed. After the graphite 306 is fixed, the staff installs the positioning shell 301 on the surface of the nut 2. At this time, one side of the graphite 306 is inserted into the contact surface between the ball head seat 1 and the ball head body 4. The graphite 306 can lubricate the ball head body 4. And during the lubrication process of the graphite 306, the surface of the graphite 306 will gradually wear. At this time, under the reaction force of the return spring 307, the positioning frame 302 and the graphite 306 are driven to move, and the ball head body 4 can be continuously lubricated, thus reducing the maintenance efficiency of the staff.
