Embodiment 1

[0020] like Figure 1-Figure 4 Shown, a kind of drill bit that is used for desk board drilling that is convenient to replace drill bit tip comprises connecting arm 1, drill bit 2, drill bit tip 3, and described drill bit 2 is cylindrical, and drill bit 2 is connected with main frame through connecting arm 1, The drill bit 2 includes a motor 21 and a drill bit storage part 22. The lower end of the motor 21 is connected with a motor rotating gear 211 passing through the drill bit storage part 22. The drill bit storage part 22 is provided with a movable channel 23 radially. The inside of the drill bit storage part 22 is evenly provided with a plurality of accommodation chambers along the circumferential direction, and the accommodation chamber includes a storage space and a movable space 223. Also be provided with drill bit aisle 221, drill bit connector is housed inside the accommodation chamber, described drill bit connector is successively drill bit replacement part 224, drill...

Embodiment 2

[0023] This embodiment is further optimized on the basis of Embodiment 1. A handle is provided on the part of the drill tip replacement part 224 protruding from the drill tip storage part 22, and an information card of the drill tip 3 is arranged on the handle. In this embodiment, The setting of the handle makes it easier to operate when replacing the drill tip; the setting of the information card makes the information of the drill tip to be replaced clear at a glance, which is convenient for replacement.

Embodiment 3

[0025] This embodiment is further optimized on the basis of Embodiment 1, the motor 21 and the drill bit storage part 22 are movably connected.

[0026] In this embodiment, the lower end of the motor is provided with an external thread, and the drill bit storage part 22 is provided with an internal thread, which is connected by threads to facilitate installation and disassembly, and to replace worn drill bits in time.

Abstract

The invention relates to a drill used for drilling a desk board and allowing drill bits to be replaced conveniently, and relates to the field of education equipment manufacturing. The drill is cylindrical and is connected with a main machine through a connecting arm. The drill comprises a motor and a drill bit storage part. The lower end of the motor is connected with a motor rotating gear penetrating through the drill bit storage part. The drill bit storage part is provided with moving channels in the radial direction. A plurality of containing cavities are evenly formed in the drill bit storage part in the circumferential direction. Each containing cavity comprises a storage space and a moving space. A drill bit storage table is arranged in each storage space. A drill bit passage is further formed between each moving space and the corresponding drill bit storage table. A drill bit connecting piece is arranged in each containing cavity. Each drill bit connecting piece sequentially comprises a drill bit replacement portion, a drill bit rotating shaft, a drill bit rotating gear and a drill bit mounting portion from top to bottom. The drill bits for different hole diameters are connected to the lower ends of the drill bit mounting portions respectively. The time for replacing the drill bits is shortened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of educational equipment production, in particular to a drill bit for drilling desk boards which is convenient for replacing the drill tip. Background technique [0002] Desks are essential educational equipment for schools. They are composed of different desk boards and brackets. Before the desk boards are installed, small holes must be drilled on the boards so that different desk boards can be combined into desks. Desk drilling machine is a kind of machine used in the drilling process of desks. It is often required to drill multiple small holes with different apertures on the same desk. In the prior art, a desk is completely drilled. The small holes often need to replace the drill tip several times to meet the requirements of different apertures. The repeated replacement of the drill tip causes a waste of manpower and material resources, which seriously affects the work efficiency. Contents of the invention [00...
