In the technical scheme, as the cam shaft phaser gear is arranged on the rotary table and is positioned through the central boss and the two positioning pins of the rotary table, and the three bolt holes on the rotary table correspond to the three bolt holes on the cam shaft phaser gear, which are needed to be marked with the anti-skid patterns, so that any bolt hole is aligned with the bolt of the limiting mechanism only by rotating the rotary table, and the bolt can be automatically inserted into the bolt hole to limit the rotation of the rotary table, thereby accurately and quickly rotating the threaded hole to be marked with the anti-skid patterns to the corresponding position and fixing the threaded hole, thus not only ensuring the marking quality, but also improving the working efficiency.

Further, an upward vertical rod is arranged at the periphery of the turntable corresponding to the locking pin hole, a cross rod is arranged at the top of the vertical rod, the vertical rod and the cross rod form a 7 shape, an elastic pin is arranged at the position of the cross rod corresponding to the locking pin hole, the pin head can be inserted into the locking pin hole by pressing the elastic pin downwards, and the elastic pin automatically returns upwards after the hand is loosened. The elastic pin is matched with the lock pin hole on the cam shaft phaser gear, so that the functions of reminding and error proofing can be achieved, and the situation that workers put the upper end face and the lower end face of the cam shaft phaser gear reversely is avoided, because if the upper end face and the lower end face of the cam shaft phaser gear are put reversely, the elastic pin is surely pressed.

In one embodiment, the upper end surface of the base is also provided with a central boss, the rotary disc is provided with a central shaft hole, and the rotary disc is sleeved on the central boss of the base through the central shaft hole and can rotate around the central boss.

In one embodiment, a compression spring is arranged between the pin head of the pin and the side vertical plate, and when the turntable is rotated to align any pin hole with the pin, the pin can be inserted into the pin hole under the action of the elastic force of the compression spring so as to limit the rotation of the turntable.

In one embodiment, a tension spring is arranged between the pin head of the elastic pin and the cross rod, the pin head can be inserted into the lock pin hole by pressing the elastic pin downwards, and the elastic pin automatically returns upwards under the action of the tension spring after the hand is loosened.

In one embodiment, two locating pins of the turntable are used for being inserted into any two screw holes on the cam shaft phaser gear, wherein the screw holes are needed to be marked with anti-skid patterns for locating. As the two locating pins are inserted into the two screw holes which need to be marked with the anti-skid patterns, the anti-skid mark can also play a role in marking.

In one embodiment, the base is mounted to the table by a set screw.
