Please refer to fig. 2 and fig. 3, which are a cross-sectional structure diagram of the height-adjustable scriber of the present invention and a cross-sectional structure diagram of the height-adjustable scriber after fine adjustment.

The upper end surface of the base 1 is provided with an installation groove 11 for installing the bracket 5; a through hole 12 is horizontally arranged in the base 1 corresponding to the mounting position of the support 5, and a support resetting mechanism is arranged in the through hole 12.

The clamping mechanism comprises a scriber locking nut 44, a scriber locking clamp 41, a scriber locking clamp sleeve 43 and a scriber clamp 42, and the scriber locking clamp 41 is movably sleeved on the guide post 2 through the scriber locking clamp sleeve 43; one end of the scriber chuck 42 penetrates through the scriber 3, and the other end of the scriber chuck penetrates through the scriber locking chuck 41 and is connected with the scriber locking nut 44.

The swing adjusting mechanism comprises a fine adjusting screw 71, a through screw hole 72 is formed in one side of the support 5, and the fine adjusting screw 71 is arranged in the through screw hole 72 in a threaded mode.

One end of the bracket 5, which is far away from the positioning pin 6, is provided with a through screw hole 72 for a fine adjustment screw 71 to be screwed, and one end of the bracket, which is close to the positioning pin 6, is connected with a guide post adjusting nut 92.

The support reset mechanism comprises a spring 81, a spring adjusting screw 82 and a thimble 83, the spring 81 is positioned in the through hole 12 in the base 1, the spring adjusting screw 82 is arranged at one end of the through hole 12 far away from the direction of the positioning pin 6, and the spring adjusting screw 82 is connected with the spring 81; one end of the thimble 83 is connected to the spring 81, and the other end is exposed out of the base 1 and contacts with the bracket 5.

The locking mechanism comprises a guide post clamping collet 91 and a guide post adjusting nut 92, one end of the guide post clamping collet 91 clamps the guide post 2, and the other end is connected with the guide post adjusting nut 92.

In operation, firstly, the approximate height of the scriber 3 is adjusted according to the working requirement, the scriber locking nut 44 is unscrewed, the position of the scriber 3 relative to the scriber chuck 42 can be adjusted, and the scriber 3 moves up and down along the scriber chuck 42; the position of the gripping mechanism relative to the guide post 2 can also be adjusted by moving the scriber 3 with the gripping mechanism up and down along the guide post 2, thereby adjusting the scriber 3 to a corresponding height. After adjusting to the corresponding position, the scriber lock nut 44 is tightened. If the position of the guide post 2 needs to be adjusted, the guide post adjusting nut 92 can be rotated to adjust the position of the guide post 2.

Next, the height of the scribe pin 3 is finely adjusted, and after the scribe pin lock nut 44 and the post adjusting nut 92 are adjusted, the position of the scribe pin 3 is finely and accurately adjusted by rotating the fine adjustment screw 71.

When the fine adjustment screw 71 is rotated, the bracket 5 swings relative to the base 1, the end part of the fine adjustment screw 71 is abutted against the bottom of the mounting groove 11, and when the fine adjustment screw 71 is rotated, the bracket 5 swings upwards along the thread, so that the swing of the bracket 5 is realized. The swing of the bracket 5 drives the guide post 2 to swing, so that the scriber 3 clamped on the guide post swings.

When the fine adjustment screw 71 is rotated clockwise, the end of the fine adjustment screw 71 is abutted against the bottom of the mounting groove 11, so that the support 5 swings upwards along the thread, the support 5 swings relative to the base 1, the guide pillar 2 fixed on the support 5 swings outwards along with the scriber 3 towards the base 1, the end of the support 5 in contact with the thimble 83 extrudes the thimble 83, the spring 81 is extruded by the thimble 83 to generate elastic deformation, the kinetic energy is converted into elastic potential energy, the spring 81 stores certain potential energy, and at the moment, the support resetting mechanism plays a self-locking role in fixing the position of the support 5. The height of the needle head of the scriber 3 is increased relative to that before fine adjustment, and fine adjustment of the height of the scriber 3 is realized through rotation of the fine adjustment screw 71. When the height of the scriber 3 needs to be adjusted again, the scriber tool needs to be reset, the fine adjustment screw 71 is rotated anticlockwise, the support 5 swings downwards along the threads, meanwhile, the spring 81 which is extruded before rebounds, elastic potential energy is converted into kinetic energy, the spring 81 pushes the thimble to reset, the thimble 83 applies force which rotates along the positioning pin 6 to the support 5, the support 5 is reset, and therefore the support 5 is in seamless contact with the mounting groove 11.
