[0029] The armrest assembly 1 in the figure is designed with a left armrest 11, a right armrest 12, a front armrest 13, and a rear armrest 14. The front armrest 13 and the rear armrest 14 are symmetrically arranged between the left armrest 11 and the right armrest 12. The above-mentioned words representing the orientation are positioned relative to the user as a reference object, and other names such as first, second, etc. can also be used. The above-mentioned left armrest 11 and right armrest 12 have the same structure and are symmetrically arranged, and the front armrest 13 and the rear armrest 14 have the same structure and are symmetrically arranged. As shown in the figure, the left armrest 11 and the right armrest 12 in the figure are both straight hollow round tube structures such as straight strips, and the front armrest 13 and the rear armrest 14 are U-shaped hollow round tube structures. At the same time, the arc transition assembly is realized through the arc tube and the end position of the left armrest 11 and the right armrest 12. Through this design, the force of other components such as the driver 7 can be uniform. In order to assemble with other components, such as the handle assembly 2 and the mounting platform 3, the above-mentioned armrest has a screw hole structure at the corresponding position.

[0030] The handle assembly 2 in the figure is designed with a left handle 21 and a right handle 22 structure. Each handle has a hollow structure inside and is composed of two handle shells 23 that cooperate with each other. The left handle 21 is installed on the left handrail 11, and its overall structure is similar to that of a flashlight. The outer surface has a texture design that is easy to grasp. The right handle 22 is installed on the right handrail 12, and its structure is also similar to that of a flashlight. The right handle 22 has a switch 221 and a lever 222 design added to it. The inside has corresponding electronic components that cooperate with the above-mentioned button 43 and lever 222. The above-mentioned electronic components cooperate with the main control of the entire electric drill to control the switch 221 and power of the device in turn. The sensor plate 82 component of the gyroscope sensor 8 can be placed inside the left handle 21 or the right handle 22, so that it is far away from the driver 7, so that various parameters can be detected more accurately and data can be sent to the main controller.

[0031] The main structure of the mounting platform 3 in the figure is a flat plate structure similar to a tray, and its two end portions are curved structures with openings, so that they can be respectively mounted on the front armrest 13 and the rear armrest 14 through the curved parts, and screw holes are designed on the curved structure to facilitate fixing the entire mounting platform 3 on the front armrest 13 and the rear armrest 14 by screws. The middle part of the mounting platform 3 has a hole for placing the driver 7, and a plurality of long concave reinforcing ribs 31 are designed near the middle part, thereby improving the strength of the entire mounting platform 3.

[0032] The battery pack assembly 4 in the figure is designed with two battery packs, namely the first battery pack 41 and the second battery pack 42. The two battery packs are symmetrically mounted on the battery holder 5 and electrically connected to the battery holder 5. Each battery pack is designed with a button 43 and a buckle 44 structure, wherein the button 43 is configured with a spring to reset the button 43 and the button 43 allows the buckle 44 to be snapped into the slot 51 of the battery holder 5. Each of the battery packs is designed with a slot 45 structure for conducting electricity in accordance with the existing method, and the battery holder 5 is correspondingly designed with a similarly conducting plug 52, so that the battery pack can supply power to the battery holder 5 by configuring the plug 52 in the slot 45 to complete the power-on configuration.

[0033] The housing 6 in the figure is mainly used to protect the driver 7, and is composed of two parts, namely a left housing 61 and a right housing 62. The interior of the housing 6 is a hollow structure for arranging the driver 7.

[0034] The gyro sensor 8 in the figure is a six-axis gyro, which senses changes in the horizontal and vertical directions, and has two components, a sensor head 81 and a sensor plate 82. The sensor head 81 is arranged on the top of the driver 7 and the inner position of the housing 6, and the sensor plate 82 can be arranged on the left housing 61 or the right housing 62. In practical applications, the sensor plate 82 can also be concentrated in the control board, which reduces external lines and saves space.

[0035] The driver 7 in the figure is an existing component, on which a drill bit 9 is arranged. The motor inside the driver 7 drives the drill bit 9 to rotate so as to complete the drilling operation.
