[0032] Please refer to Figure 2 The clamping frame 4 is fixedly provided with a spring guide rod 8, the clamping adjusting table 9 slides on the spring guide rod 8, and the reset spring 11 is sleeved outside the spring guide rod 8.

[0033] In example 1, the reference adjusting table 6 is driven by the screw rod 5 to move up and down, and the clamping adjusting table 9 is moved by cooperation of the plug-in block 10 and the plug-in hole 7, so as to adjust the height of the drill sleeve body 22, and adapt to drill workpieces of different thicknesses.

[0034] Specifically, the operator places the drill sleeve body 22 in the limiting groove 21 in the fixed frame 3, and then starts the electric push rod 25 on the clamping seat 2, and the driving end of the electric push rod 25 drives the clamping frame 4 to move towards the fixed frame 3; during the movement of the clamping frame 4, the sliding seat 28 at the bottom thereof slides along the slide 27 of the clamping seat 2, and the structural rib plate 26 moves synchronously with the clamping frame 4 to ensure that the clamping frame 4 does not deviate radially; continue to move until the insertion block 10 at the connection end of the clamping adjustment table 9 is inserted into the insertion hole 7 of the reference adjustment table 6 (when the insertion block 10 approaches the insertion hole 7, if not aligned, the operator can manually press the clamping adjustment table 9 to assist the insertion block 10 to align with the insertion hole 7, and when pressing, the return spring 11 is retracted along the spring guide rod 8), at this time, the two limiting grooves 21 are combined to fix the drill sleeve body 22.

[0035] According to the thickness of the workpiece, the motor in the fixed seat 1 is started, the motor drives the lead screw 5 to rotate clockwise, the lead screw 5 is screwed with the reference adjustment table 6, drives the reference adjustment table 6 to adjust downward along the slide groove 12 of the fixed frame 3, the sliding block 13 at the connection end of the reference adjustment table 6 slides along the slide groove 12 to limit the radial shaking of the reference adjustment table 6; the reference adjustment table 6 drives the clamping adjustment table 9 to move synchronously through the locking structure of the insertion block 10 and the insertion hole 7, the sliding block 13 of the clamping adjustment table 9 slides along the slide groove 12 of the clamping frame 4, the spring guide rod 8 provides auxiliary guidance for the clamping adjustment table 9 to avoid deviation; at the same time, the reference adjustment table 6 and the clamping adjustment table 9 respectively drive the corresponding corrugated splash guard 15 to retract along the auxiliary mounting block 14, to block the subsequent drilling debris from splashing into the fixed frame 3 and the clamping frame 4 (after each processing is completed, the reference adjustment table 6 needs to be reset, and after resetting, the insertion hole 7 and the insertion block 10 are aligned, so that the insertion block 10 can be directly inserted into the insertion hole 7 when used next time).

[0036] In embodiment 2, the taper structure is adapted and fitted with the anti-loose inclination angle 23 to form a “wedge self-locking” effect, which converts the force into radial clamping force through the contact between the taper and the anti-loose inclination angle 23, to limit the axial movement of the drill sleeve body 22.

[0037] Specifically, when the insertion block 10 at the connection end of the clamping adjustment table 9 is inserted into the insertion hole 7 of the reference adjustment table 6, the two limiting grooves 21 are combined, and at this time, the bottom of the drill sleeve body 22 is fitted with the groove bottom of the limiting groove 21, and the “wedge self-locking” effect is formed: the taper of the drill sleeve body 22 converts the axial pressure into radial clamping force to limit the axial movement of the drill sleeve body 22.

[0038] In embodiment 3, when the clamping force is insufficient due to long-term use of the anti-loose inclination angle 23, the positions of the two drill templates 18 on the reference adjustment table 6 and the clamping adjustment table 9 can be adjusted to prolong the service life.

[0039] Specifically, if the anti-loosening inclined surface 23 in the limiting groove 21 is obviously worn, resulting in insufficient clamping force of the drill sleeve body 22, the position needs to be compensated by adjusting the drill jig plate 18, both hands are inserted into the auxiliary groove 24, the drill jig plate 18 is pulled up, the drill jig plate 18 drives the positioning pin 17 to disengage from the positioning hole of the positioning block 16, the tension spring 20 is further stretched in the pulling process, the drill jig plate 18 is rotated by half a circle, the non-worn limiting groove 21 on the drill jig plate 18 is aligned with the direction of the drill sleeve body 22; the repositioned drill jig plate 18 is aligned with the positioning block 16, the drill jig plate 18 drives the positioning pin 17 to align with the positioning hole of the positioning block 16, the drill jig plate 18 is slowly lowered until the positioning pin 17 is completely inserted into the positioning hole of the drill jig plate 18; at this time, the tension spring 20 releases the elastic force, continuously applies the pulling force to the drill jig plate 18, and the drill jig plate 18 is tightly attached to the positioning block 16 again, at this time, the non-worn area of the anti-loosening inclined surface 23 is attached to the tapered surface of the drill sleeve body 22, and the clamping force is restored to the initial state.

[0040] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
