Referring to fig. 1-3, a combination drill bit for convenient use includes a disc 1, a stem 2, a collar 3, a hand-held drill 4 and a mounting head 5;
a vertical rod 2, a lantern ring 3 positioned above the left side surface of the vertical rod 2, a handheld drilling machine 4 positioned in the lantern ring 3 and an installing head 5 positioned at the output end of the handheld drilling machine 4 are rotatably arranged in the center of the upper surface of the disc 1 through a bearing;
the disc 1 comprises a sleeve spring 101, a bearing 102, a drill bit 103 and a through box 104;
the left direction, the right direction, the inner direction and the outer direction of the upper surface of the disc 1 are both fixedly provided with a sleeve spring 101, the top of the sleeve spring 101 is fixedly provided with a bearing 102, a drill bit 103 is fixedly arranged in an inner rotating ring of the bearing 102, and the left direction, the right direction, the inner direction and the outer direction of the upper surface of the disc 1 are both provided with a through box 104 in a penetrating mode.
The drill bits 103 on the four bearings 102 have different diameters, and are mounted on the handheld drilling machine 4 through different drill bits 103, so that holes with different diameters can be conveniently drilled.
Wherein, the drill bit 103 runs through the penetration box 104, which is convenient for the drill bit 103 to move up and down.
When the sleeve spring 101 is in a natural extension state, the bottom horizontal height of the drill bit 103 is equal to the bottom horizontal height of the disc 1, so that the drill bit 103 which is not used is prevented from influencing the drill bit 103 which works.
When the sleeve spring 101 is in the maximum compression state, the top horizontal height of the drill 103 is lower than the bottom horizontal height of the mounting head 5, so that the drill 103 is conveniently mounted on the mounting head 5.
By arranging a plurality of drill bits 103 with different diameters on the disc 1, when the drill bits 103 with corresponding diameters are required to be used, the drill bits 103 are pressed downwards, so that the drill bits 103 drive the bearing 102 to move downwards, the sleeve springs 101 are in a compressed state, then the disc 1 is rotated along the vertical rod 2, so that the drill bits 103 are positioned below the mounting head 5, and the drill bits 103 are mounted on the mounting head 5, so that when the handheld drilling machine 4 is started, the handheld drilling machine 4 drives the mounting head 5 to rotate, so that the drill bits 103 synchronously rotate to perform drilling operation;
through being provided with cup joint spring 101, because drill bit 103 installs on the bearing 102 at cup joint spring 101 top, and when cup joint spring 101 was in the natural extension state, the bottom level of drill bit 103 equals the bottom level of disc 1 to guarantee under the condition that has no external force, drill bit 103 can not stretch out the bottom that runs through case 104, guarantee that drill bit 103 that does not use can not influence the normal work that is using drill bit 103.
The second embodiment:
referring to fig. 1 to 5, the difference from the first embodiment is that:
wherein, a hexagonal column 501 is fixedly arranged at the center of the bottom surface of the mounting head 5, and a hexagonal box 105 is embedded at the center of the upper surface of the drill 103.
The corresponding side lengths of the hexagonal column 501 and the hexagonal box 105 are the same, and the hexagonal column 501 can be embedded in the hexagonal box 105, so that the drill 103 can be conveniently installed in the installation head 5.
By arranging the hexagonal column 501 and the hexagonal box 105, when the drill bit 103 is mounted on the mounting head 5, the mounting effect can be achieved by sleeving the hexagonal box 105 on the drill bit 103 in the hexagonal column 501, and the mounting is more convenient;
when the drill bit 103 is mounted on the mounting head 5, the sleeve spring 101 at the drill bit 103 is in a compressed state, and under the action of the elastic force of the sleeve spring 101, the drill bit 103 moves upwards, so that the hexagonal box 105 is always sleeved on the hexagonal column 501, the drill bit is prevented from falling off, and the mounting stability is ensured.
The above is only the preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, without departing from the concept of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
