In this embodiment, the base plate front-to-back adjustment assembly 4 further includes a front-to-back fine-tuning screw 44. The rear end of the fixing block 41 has a front-to-back fine-tuning screw hole 411. The front-to-back fine-tuning screw 44 is screwed into the front-to-back fine-tuning screw hole 411, and the screw body 422 abuts against the nut of the front-to-back fine-tuning screw 44. Rotating the front-to-back fine-tuning screw 44 adjusts the length by which the nut of the front-to-back fine-tuning screw 44 extends beyond the front-to-back fine-tuning screw hole 411.

[0027] Preferably, the quick-change adjustment mechanism further includes a base plate locking assembly 5, which includes a shaft pin knob 51, a rear shaft pin 52, a front shaft pin 53, and an eccentric locking rod 54. The bottom of the base plate 2 also has an eccentric rod mounting groove 27 communicating with the fixing block mounting groove 25. The base plate 2 has a rear shaft pin rotating hole 28 penetrating the rear of the eccentric rod mounting groove 27 at its rear end, and a front shaft pin rotating hole 29 at its front end. The rear shaft pin 52 is rotatably inserted into the rear shaft pin rotating hole 28, with its rear end fixed to the shaft pin knob 51 and its front end passing through the rear shaft pin knob 53. The pivot hole 28 is fixedly connected to the rear end of the eccentric locking rod 54. The front pivot 53 is rotatably inserted into the front pivot hole 29. The rear end of the front pivot 53 extends rearward from the front pivot hole 29 and is fixedly connected to the front end of the eccentric locking rod 54. The central axis of the front pivot 53 and the central axis of the rear pivot 52 are on the same straight line. The central axis of the eccentric locking rod 54 is located outside the central axis of the front pivot 53. The eccentric locking rod 54 can press against the fixing block 41. In this embodiment, a locking protrusion 412 protrudes from the upper part of the side wall of the fixing block 41 near the eccentric locking rod 54. The lower end face of the locking protrusion 412 forms a tightening slope 4121 that slopes downward from top to bottom towards the fixing block 41. The eccentric locking rod 54 can press against the tightening slope 4121.

[0028] In use, the fixing block 41 is horizontally fixed on the working plane. The workpiece is installed on the top of the top plate 1. When it is necessary to adjust the front and back position of the bottom plate 2, first rotate the shaft nail knob 51 to loosen the fixing block 41 by the eccentric locking rod 54. Then rotate the front and back knob body 421 to adjust the front and back position of the front and back screw bodies 422. When the front and back screw bodies 422 move forward, they push the fixing block 41, thereby causing the bottom plate 2 to move backward relative to the fixing block 41. When the front and back screw bodies 422 move backward, push the bottom plate 2 forward so that the front and back screw bodies 422 abut against the fixing block 41 again, thereby causing the bottom plate 2 to move forward relative to the fixing block 41. Rotate the left and right knob body 311 to move the left and right adjustment block 32 from front to back to the right or from back to front to the left in the left and right adjustment groove 21. This will cause the adjustment pin 33 to move from front to back to the right or from back to front to the left. When the adjustment pin 33 moves backward relative to the upper adjustment groove 11, the top plate 1 moves to the right relative to the bottom plate 2. When the adjustment pin 33 moves forward relative to the upper adjustment groove 11, the top plate 1 moves to the left relative to the bottom plate 2, thereby completing the adjustment of the left and right position of the top plate 1.

[0029] This invention allows for flexible adjustment of the front-to-back and left-to-right positions of the workpiece on the top plate, making it convenient and practical to use.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
