[0001] The utility model relates to the technical field of portable small-sized magnetic base drills, in particular to a portable small-sized magnetic base drill. Background Art

[0002] The magnetic drill generates a magnetic field when the electromagnet on the base of the magnetic drill is powered on, which is adsorbed on the steel part. Then the magnetic drill motor runs at high speed to drive the drill bit to drill holes or thread the steel plate.

[0003] The inventor discovered during daily use of a magnetic drill that a general magnetic drill would generate debris when drilling holes in metal plates. Since the debris is light in weight, it will splash everywhere under the drive of the drill bit, which may affect the operator's drilling and cause problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a portable small magnetic base drill.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a portable small magnetic base drill, including a drill body, the bottom of the drill body is rotatably connected to an electromagnetic plate, the upper top of the drill body is fixedly connected to a motor, the drill body is made of plastic material, a rectangular groove is opened on the side of the drill body, a threaded rod is rotatably connected inside the rectangular groove, a slider is threadedly connected to the surface of the threaded rod, a driving machine is fixedly connected to the side of the slider, a drill bit is fixedly connected to the output end of the driving machine, a protective device is provided at one end of the driving machine, a cleaning device is provided at one end of the driving machine, the protective device includes a protective cover fixedly connected to one end of the driving machine, and a telescopic cover is slidably connected inside the protective cover.

[0006] The effect achieved by the above components is: under the action of the protective cover and the telescopic cover, there will be no metal debris splashing when drilling. When using a small magnetic drill, the electromagnetic plate is placed on the surface of the metal plate to be drilled and the electromagnetic plate is energized, so that the electromagnetic plate generates magnetism and is attracted to the surface of the metal plate. The motor is started to rotate the threaded rod, which in turn drives the slider to move downward, and the drive motor is started to rotate the drill bit, thereby drilling a hole in the metal plate, thereby achieving the drilling phenomenon.

[0007] Preferably, a first spring is fixedly connected inside the protective cover, and the other end of the first spring is fixedly connected to a telescopic cover.

[0008] The effect achieved by the above components is that under the action of the first spring, the telescopic cover can always extend out of the interior of the protective cover.

[0009] Preferably, one end of the protective cover is fixedly connected to a baffle, and one end of the telescopic cover is fixedly connected to a baffle.

[0010] The effect achieved by the above components is that under the action of the baffle, the telescopic cover will not be separated from the protective cover.

[0011] Preferably, a round strip is fixedly connected to the surface of the baffle, and the round strip is a rubber strip.

[0012] The effect achieved by the above components is that, under the action of the round bar, the baffles will not be in rigid contact with each other, thus avoiding the baffles from being damaged due to long-term impact.

[0013] Preferably, a circular groove is provided on the side surface of the baffle, and a ball is rotatably connected inside the circular groove.

[0014] The effects achieved by the above components are as follows: under the action of the ball bearing, the telescopic cover can be extended quickly, avoiding the phenomenon that the telescopic cover is stuck inside the protective cover due to the large friction force. When using the magnetic base drill, after the drill body is sucked to the appropriate position of the metal plate through the electromagnetic plate, the motor is started to move the driving machine downward, and the driving machine is started so that the drill bit drills a hole on the surface of the metal plate. Then, under the action of the protective cover and the telescopic cover, the metal debris generated by the drilling is confined inside the protective cover, thereby avoiding the splashing phenomenon. When the drilling is completed, the driving machine drives the drill bit to move up, and under the action of the first spring, the telescopic cover is extended and reset. Under the action of the baffle, the telescopic cover will not be separated from the protective cover. Under the action of the round bar, the baffles will not be in rigid contact with each other, thereby avoiding the phenomenon that the baffles are damaged due to long-term impact. Under the action of the ball bearing, the telescopic cover can be extended quickly, avoiding the phenomenon that the telescopic cover is stuck inside the protective cover due to the large friction force, thereby achieving the protective effect.

[0015] Preferably, the cleaning device includes a telescopic rod fixedly connected to one end of the driving machine, a spring fixedly connected to the inside of the telescopic rod, a push ring fixedly connected to one end of the telescopic rod, a scraper ring fixedly connected to one end of the push ring, and the scraper ring is tightly attached to the surface of the drill bit.

[0016] The effect achieved by the above components is that under the action of the scraper ring, the metal wire wrapped around the surface of the drill bit is cleaned, thereby achieving the effect of pushing out.

[0017] Preferably, a groove is provided on the surface of the push ring, and a ball is rotatably connected inside the groove.

[0018] The effect achieved by the above components is that under the action of the sphere, the friction between the push ring and the drill bit is reduced, thereby facilitating the push ring to slide on the surface of the drill bit.

[0019] Preferably, a circular ring is provided on the side surface of the push ring, and the circular ring fits tightly with the surface of the drill bit.

[0020] The effects achieved by the above components are: under the action of the circular ring, the metal wire will not enter between the push ring and the drill bit, thereby achieving a protective effect. When the drill bit finishes drilling, the push ring moves down under the action of the spring inside the telescopic rod, thereby driving the scraper ring to move on the surface of the drill bit, thereby pushing out and cleaning the metal debris wrapped around the surface of the drill bit. Under the action of the ball, the friction between the push ring and the drill bit is reduced, thereby facilitating the push ring to slide on the surface of the drill bit. Under the action of the circular ring, the metal wire will not enter between the push ring and the drill bit, thereby achieving a protective effect and a cleaning effect.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] In the utility model, by arranging a protective device, when using a magnetic base drill, after the drill body is sucked to a suitable position of the metal plate by the electromagnetic plate, the motor is started to move the driving machine downward, and the driving machine is started so that the drill bit drills a hole on the surface of the metal plate, and then under the action of the protective cover and the telescopic cover, the metal debris generated by the drilling is confined inside the protective cover, thereby avoiding the splashing phenomenon. When the drilling is completed, the driving machine drives the drill bit to move upward, and under the action of the first spring, the telescopic cover is extended and reset, and under the action of the baffle plate, the telescopic cover will not be separated from the protective cover, and under the action of the round bar, the baffle plates will not have a rigid contact, thereby avoiding the baffle plate from being damaged by long-term impact, and under the action of the ball bearing, the telescopic cover can be quickly extended, avoiding the telescopic cover being stuck inside the protective cover due to large friction, thereby achieving the protective effect, thereby solving the problem that the drill bit easily drives the generated debris to splash when drilling.
