Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Referring to Figures 1-4 , a quick drill length measuring device includes a connecting table 1 and an infrared rangefinder 2. A resilient clamp 3 is fixedly connected to the bottom of the connecting table 1. A bolt 4 is threadedly connected to the inner wall of the bottom end of the resilient clamp 3. A moving plate 5 is placed on the upper surface of the connecting table 1. A reflecting plate 6 is fixedly connected to the side wall of the top end of the moving plate 5. A magnetic plate 7 is fixedly connected to the side wall of the bottom end of the moving plate 5. An insertion plate 8 is fixedly connected to the bottom of the moving plate 5. A slot is formed in the inner wall of the connecting table 1, and the insertion plate 8 is inserted into the inner wall of the slot.

[0023] An insertion opening is formed in the inner wall of the bottom end of the insertion plate 8. An insertion block 9 is inserted into the inner wall of the insertion plate 8 at the insertion opening. A groove is formed in the inner wall of the connecting table 1 at the slot, and the inner wall of the groove of the connecting table 1 matches the insertion block 9.

[0024] A cavity is formed in the inner wall of the connecting table 1. A spring 12 is fixedly connected to the inner wall of the cavity of the connecting table 1.

An opening is formed in the inner wall of the bottom end of the insertion plate 8 at the insertion opening, and the rod wall of the pressing rod 10 slides on the inner wall of the insertion plate 8 at the opening.

[0025] During use, push the pressing plate 11 to press the pressing rod 10 to move, so that the insertion block 9 extends into the inside of the groove. The moving plate 5 can be pulled to pull out the insertion plate 8 at the bottom of the moving plate 5 from the inside of the slot, and the moving plate 5 can be taken out. The moving plate 5 can be adsorbed to one end of the drill by the magnetic plate 7 on the side wall of the moving plate 5. The connecting table 1 and the infrared rangefinder 2 can be fixedly arranged at one end of the drill away from the moving plate 5 through the resilient clamp 3.
