A positioning component 3 is arranged at the lower end of the movable groove 201. Through the arrangement of the positioning component 3, four positioning blocks 303 can be simultaneously inserted into the four positioning grooves 101 on the inner wall of the ATC cam body 1, thereby completing the rapid installation and fixation between the installation shaft 2 and the ATC cam body 1, further improving the installation efficiency of the ATC cam body 1. Moreover, the four positioning blocks 303 are inserted around the inside of the ATC cam body 1 to improve the installation stability between the ATC cam body 1 and the installation shaft 2. The positioning component 3 cooperates with the four positioning grooves 101. Through grooves 202 are opened on both sides of the lower end of the installation shaft 2, and one side of the through groove 202 is communicated with the inside of the movable groove 201. A conical pressure rod 4 is movably installed in the middle of the movable groove 201, and connecting rods 401 are fixedly installed on both sides of the upper end of the conical pressure rod 4. One end of the connecting rod 401 extends to the outside of the installation shaft 2 through the adjacent through groove 202. A second return spring 6 is fixedly installed at the middle position of the top of the conical pressure rod 4, and the top of the second return spring 6 is fixedly installed on the top wall of the movable groove 201. A collar 5 is sleeved on the surface of the installation shaft 2, and the bottom of the collar 5 is placed on the top of one end of the two connecting rods 401. External threads 203 are provided on the surface of the installation shaft 2, and a threaded sleeve 7 is threadedly installed on the surface of the installation shaft 2 through the external threads 203, and the bottom of the threaded sleeve 7 is placed on the surface of the top of the collar 5.

[0021] Please refer to Figures 2-4, in the embodiment of the present utility model: The positioning assembly 3 includes: a groove 301 and a push rod 302. There are four grooves 301, and the four grooves 301 are equidistantly arranged along the circumference on the surface of the lower end of the mounting shaft 2. The four grooves 301 correspond to the four positioning grooves 101 one by one. A positioning block 303 is movably installed inside the groove 301, and a push rod 302 is fixedly connected horizontally to the middle of one side of the positioning block 303. One end of the push rod 302 movably penetrates into the inside of the movable groove 201, and one end of the push rod 302 is placed on the surface of one end of the adjacent push rod 302. The bottom of the conical pressure rod 4 is placed on the surface of the tops of one ends of the four push rods 302. A fixing ring 304 is fixedly connected to the middle of the push rod 302, and a first return spring 305 is sleeved on the surface of the middle part of the push rod 302. The settings of the first return spring 305 and the second return spring 6 facilitate the rapid reset of the push rod 302 and the conical pressure rod 4. After the disassembly of the ATC cam body 1 and the mounting shaft 2 is completed, it is convenient for subsequent reinstallation. One end of the first return spring 305 is fixedly connected to the inner wall of the movable groove 201, and the other end of the first return spring 305 is fixedly connected to the surface of one side of the fixing ring 304. During the rapid installation of the ATC cam body 1, first, the lower end of the mounting shaft 2 is inserted into the middle of the ATC cam body 1, and the thread sleeve 7 is rotated downward towards the ATC cam body 1. At this time, the bottom of the thread sleeve 7 squeezes the collar 5 to descend, so that the bottom of the collar 5 squeezes the two symmetrical connecting rods 401 to descend. At this time, the two connecting rods 401 drive the conical pressure rod 4 to descend, so that the conical surface at the bottom of the conical pressure rod 4 squeezes the inclined surfaces of one ends of the four push rods 302, causing the four push rods 302 to move in opposite directions simultaneously. The push rod 302 pushes the positioning block 303 fixed at the other end to move into the corresponding positioning groove 101. After the positioning block 303 moves into the corresponding positioning groove 101 in place, stop rotating the thread sleeve 7. At this time, the rapid installation and fixation between the mounting shaft 2 and the ATC cam body 1 are completed, thereby further improving the installation efficiency of the ATC cam body 1.

[0022] Please refer to Figure 2 and Figure 4 , in the embodiment of the present utility model: One end of the push rod 302 is provided as an inclined surface, and the inclined surface at one end of the push rod 302 cooperates with the conical surface at the bottom of the conical pressure rod 4. During the downward movement of the conical pressure rod 4, through the cooperation of the inclined surface at one end of the push rod 302 and the conical surface at the bottom of the conical pressure rod 4, the conical surface at the lower part of the conical pressure rod 4 can easily squeeze the inclined surfaces of the four equally spaced push rods 302 at one end to move in opposite directions simultaneously.

[0023] Please refer to Figure 2, in an embodiment of the present utility model: the width of the positioning block 303 is 1.2 times the width of the positioning groove 101. After the positioning block 303 moves into the corresponding positioning groove 101 in place, the positioning block 303 is located between the positioning groove 101 and the groove 301, completing the fixed connection between the ATC cam body 1 and the mounting shaft 2.

[0024] Please refer to Figure 2 , in an embodiment of the present utility model: sliding grooves are symmetrically formed on the inner wall of the through groove 202. Both sides of one end of the connecting rod 401 are fixedly connected with sliding blocks. One end of the connecting rod 401 is slidably installed in the sliding grooves on the inner wall of the adjacent through groove 202 through the sliding blocks. By slidably installing the connecting rod 401 in the corresponding through groove 202, the stability of the movement of the conical pressing rod 4 is further improved.

[0025] Please refer to Figures 1-2 , in an embodiment of the present utility model: six fixing handles are equidistantly installed on the side wall of the threaded sleeve 7 along the circumference. Through the six fixing handles on the side wall of the threaded sleeve 7, it is convenient to rotate the threaded sleeve 7.

[0026] Working principle: When quickly positioning and installing the ATC cam, first insert the lower end of the mounting shaft 2 into the middle of the ATC cam body 1, and rotate the threaded sleeve 7 to move downward towards the ATC cam body 1. At this time, the bottom of the threaded sleeve 7 presses the collar 5 to descend, so that the bottom of the collar 5 presses the two symmetric connecting rods 401 to move downward. At this time, the two connecting rods 401 drive the conical pressing rod 4 to descend, so that the conical surface at the bottom of the conical pressing rod 4 presses the inclined surfaces at one end of the four push rods 302, causing the four push rods 302 to move in opposite directions at the same time. The push rods 302 push the positioning blocks 303 fixed at the other end to move into the corresponding positioning grooves 101. After the positioning blocks 303 move into the corresponding positioning grooves 101 in place, stop rotating the threaded sleeve 7. At this time, the quick installation and fixation between the mounting shaft 2 and the ATC cam body 1 is completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
