[0019] A positioning frame 3 is installed on the side of the frame body 1. The positioning frame 3 is stamped and formed according to the model of the bench drill press on which this protective device is installed. Then, the positioning frame 3 is fixed to the outside of the frame body 1 by screws. A connecting frame 4 is slidably arranged below the positioning frame 3, and the connecting frame 4 is rotatably engaged with the chuck 2. Several balls 5 are rotatably installed on the inside of the connecting frame 4. The connecting frame 4 contacts the outside of the chuck 2 through the balls 5, and engages the connecting frame 4 with the chuck 2. During the rotation of the drill bit driven by the chuck 2, the balls 5 installed in the connecting frame 4 are used to reduce the friction between the connecting frame 4 and the chuck 2.

[0020] A positioning seat 6 is fixed to the side of the connecting frame 4, and a positioning rod 7 is fixed to the upper side of the positioning seat 6. A connecting seat 8 is fixed to the side of the positioning frame 3. The positioning rod 7 is slidably disposed in the connecting seat 8. The positioning rod 7, which is slidably disposed in the connecting seat 8, limits the position of the connecting frame 4, preventing the connecting frame 4 from moving or even detaching from the outside of the card seat 2. During the process of the card seat 2 driving the connecting frame 4 to move up and down, the positioning rod 7 slides in the connecting seat 8, positioning and guiding the connecting frame 4 disposed on the outside of the card seat 2, which facilitates the installation and use of the connecting frame 4.

[0021] A protective component is fixed to the side of the connecting frame 4 and fitted onto the outside of the drill bit. After the connecting frame 4 is connected to the jack 2, the protective component is positioned, which facilitates the installation and use of the protective component. The protective component protects the drill bit and prevents it from causing harm to personnel's health when the drill bit rotates at high speed. During the up and down movement of the drill bit, the jack 2 drives the protective component to move synchronously through the connecting frame 4, ensuring that the protective component effectively protects the drill bit.

[0022] The protective assembly includes a positioning sleeve 9 installed on the lower side of the connecting frame 4, and a protective sleeve 10 is slidably disposed on the lower side of the positioning sleeve 9. When the drill bit rotates but does not drill, the positioning sleeve 9 and the protective sleeve 10 are staggered for overall protection of the drill bit. During the drilling process, after the protective sleeve 10 contacts the workpiece, it slides outside the positioning sleeve 9 under the limiting effect of the workpiece, ensuring that the drill bit moves down to drill. During the drilling process, the positioning sleeve 9 and the protective sleeve 10 limit and collect the generated debris, reducing the debris splashing during drilling.

[0023] A limiting plate 13 is fixed to the top of the positioning sleeve 9, and a spring 12 is sleeved on the outside of the positioning sleeve 9.
