[0023] Embodiment 1:

[0024] As attached Figure 1 To Attachment Figure 6 As shown:

[0025] The utility model provides an alloy composite drill bit, comprising: a fixed block 1; the fixed block 1 adopts a rectangular block structure, and a rectangular cavity structure is provided inside the fixed block 1, a through circular through groove is provided on the top of the fixed block 1, four groups of rectangular groove structures are provided in a rectangular array around the outer wall of the fixed block 1, and a circular ring groove structure is provided at the bottom of the fixed block 1, and a circular through groove structure connected with the circular ring groove at the bottom of the fixed block 1 is provided in an annular array at the bottom of the rectangular cavity inside the fixed block 1; a shield 2 is fixedly connected in the circular ring groove at the bottom of the fixed block 1; a first slide bar 102 of a cylindrical structure is slidably provided in the circular through groove at the top of the fixed block 1, and a spring is sleeved on the outer side of the first slide bar 102; four groups of second slide bars 104 of a cylindrical structure are slidably provided on the outer side of the fixed block 1 in a rectangular array, and a spring is sleeved on the outer side of the second slide bar 104; a slider 105 of a wedge-shaped block structure is fixedly provided on the outer end of the second slide bar 104.

[0026] Among them, a drill bit 101 is fixedly arranged in the middle of the bottom of the fixed block 1; a top block 103 with a conical block structure is fixedly arranged at the bottom of the first sliding rod 102; the inner end of the second sliding rod 104 is fixedly connected with a first pin rod 106 with an L-shaped rod structure, and the bottom end of the first pin rod 106 is slidably arranged on the inner side of the circular through groove of the internal cavity of the fixed block 1; four groups of second pin rods 107 with a cylindrical structure are slidably arranged in a rectangular array in the circular through groove outside the internal rectangular cavity of the fixed block 1, and a spring is sleeved on the outer side of the second pin rod 107.

[0027] The specific usage and function of this embodiment are as follows:

[0028] When the drill bit 101 needs to be installed and used, the fixing block 1 is first inserted into the hole of the equipment installation drill bit 101, so that the top of the fixing block 1 fits with the inner end surface of the equipment installation hole, thereby pressing the first sliding rod 102 to slide downward along the circular through groove on the top of the fixing block 1, thereby driving the top block 103 to move downward, so that the top block 103 loses the limiting effect on each group of second pin rods 107, and each group of second pin rods 107 slides inward under the action of the spring on its outer side, thereby making each group of second pin rods 107 lose the limiting effect on the shield 2. After being installed to the preset depth, the fixing block 1 can be fixed and clamped. In this process, the groups of sliders 105 around the outer side of the fixing block 1 can be squeezed and made Each group of slide blocks 105 slides inward along the rectangular groove on the outside of the fixed block 1, and simultaneously drives each group of second slide bars 104 to slide inward, thereby driving each group of first pin rods 106 to slide inward, and making each group of first pin rods 106 be pulled out from the pin holes of the shield 2, thereby also losing the limiting effect on the shield 2. Only after the fixed block 1 is fully installed in place can each group of first pin rods 106 and each group of second pin rods 107 be pulled out from the pin holes of the shield 2. At this time, the shield 2 can be pulled out from the circular groove at the bottom of the fixed block 1, so that the drill bit 101 can be used normally. If the installation is not in place, the shield 2 cannot be removed, avoiding the safety hazard caused by the improper installation of the drill bit 101.

[0029] Embodiment 2:

[0030] Based on Example 1, as shown in the attached Figure 1 To Attachment Figure 6 As shown:

[0031] Among them, the shield 2 adopts a circular ring structure, and four groups of penetrating circular pin hole structures are opened in a circular array on the upper and lower sides of the top of the shield 2; an operating rod 201 of a cylindrical structure is fixedly arranged on the inner side of the bottom of the shield 2, and a spring is sleeved on the outer side of the operating rod 201; a rotating plate 202 of a circular plate-shaped structure is fixedly arranged on the top of the operating rod 201, and a penetrating rectangular through-slot structure is opened on one side of the top of the rotating plate 202, and the outer wall of the rotating plate 202 is in contact with the inner wall of the shield 2; a piston plate 203 is slidably arranged on the outer side of the operating rod 201, and the outer wall of the piston plate 203 is tightly fitted with the inner wall of the shield 2; an application rod 204 of an internally hollow rectangular rod structure is fixedly arranged on one side of the top of the rotating plate 202, a brush structure is arranged on one side of the application rod 204, and the interior of the application rod 204 is connected to the area at the bottom of the rotating plate 202 through the rectangular through-slot on the top of the rotating plate 202, and a penetrating circular through-slot structure is opened on one side of the application rod 204 in an equidistant manner.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In the present invention, when in use, anti-rust oil is filled in the area between the rotating plate 202 and the piston plate 203. When the drill bit 101 is used, the shield 2 is inserted into the annular groove at the bottom of the fixed block 1, so that each group of circular pin holes on the top of the shield 2 is aligned with the circular through grooves of the rectangular cavity inside the fixed block 1. Then the fixed block 1 and the drill bit 101 can be removed from the device, and then each group of first pin rods 106 and each group of second pin rods 107 are inserted into each group of pin holes on the top of the shield 2 under the action of the springs on their outer sides, so that the shield 2 is fixed to the bottom of the fixed block 1. It is necessary to During maintenance, the piston plates 203 can be pushed toward each other so that the piston plates 203 slide upward along the operating rod 201, thereby squeezing out the anti-rust oil from the rectangular groove of the rotating plate 202, and allowing the anti-rust oil to enter the interior of the coating rod 204, and further be discharged through the opening on one side of the coating rod 204, and then the operating rod 201 is rotated to drive the rotating plate 202 to rotate, and the anti-rust oil is applied to the outer surface of the drill bit 101 through the brush structure, thereby completing the maintenance work on the drill bit 101, and continuously protecting the drill bit 101 through the shield 2, which is beneficial to extending the service life of the drill bit 101.
