[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.

[0027] In the embodiments of this application, please refer to Figure 1-6 As shown, the lithium-ion electric drill mainly includes an electric drill body 6, which is used to protect internal components and is the main structure of the electric drill; a drill chuck 11, which is located on the upper part of the electric drill body 6 and is a base for fixing the drill bit 5; a clamp 12, which is installed on the drill chuck 11 and serves as a locking member; a fixing member 13, which is installed on the clamp 12; a support rod 17 is rotatably provided on the fixing member 13, and a laser emitter 14 is fixedly fitted on the support rod 17, and the preset drilling spacing is adjusted by adjusting the angle of the laser emitter 14 on the fixing member 13.

[0028] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0029] In one embodiment, the clamp 12 is controlled by bolts and nuts to be loose and tight, and can rotate around the drill chuck 11, driving the fixing member 13 to rotate synchronously, so that the fixing member 13 and the laser emitter 14 can rotate in the left and right directions to meet different work requirements. Specifically, when it is necessary to drill a hole above the reference hole, the fixing member can also be adjusted above the electric drill body, and when it is necessary to drill holes at intervals in the horizontal direction of the reference hole, the clamp can be rotated to a relatively horizontal position (such as the left or right side of the drill chuck) so that when drilling holes, the electric drill can also keep the handle upright for easy operation.

[0030] Specifically, the fixing member 13 is a U-shaped structure with through holes on both sides, and a plurality of scale lines are arranged on the outer wall of the U-shaped structure to indicate the drilling positions.

[0031] More specifically, the support rod 17 passes through the fixing member 13 through a through hole and is rotatably connected to the fixing member 13 . The support rod 17 is cylindrical and has a through hole in the middle. The laser emitter 14 is detachably mounted on the support rod 17 .

[0032] Preferably, the surface of the support rod 17 is covered with a layer of damping material, and there is a certain friction force between the support rod 17 and the fixing member 13, so that the laser emitter 14 has a certain limiting and fixing effect when rotating.

[0033] Reference Figure 5 The laser emitter 14 is cylindrical and is fixed on the support rod 17 through a through hole penetrating the support rod 17. It can be rotated up and down with the support rod 17 as the axis to meet different drilling spacing requirements.

[0034] Preferably, the laser emitter 14 has an independent energy supply system and power switch to save energy consumption. Preferably, the laser emitter 14 uses a button battery as an energy supply.

[0035] like Figure 5 As shown, there is an indicating arrow on the central axis of the laser emitter 14, which is used to correspond to the scale line on the fixing member 13, so as to correspond to the indicating arrow on the laser emitter 14, facilitate observation, and improve accuracy.

[0036] Furthermore, the drill chuck 11 has an indicating scale every 90 degrees in the horizontal and vertical directions for determining the horizontal and vertical positions.

[0037] Preferably, there is a lithium battery pack 7 at the lower part of the electric drill body 6 for supplying energy to the entire system.

[0038] Preferably, Figure 1As shown, the handle 3 has some stripes on its surface to increase the aesthetics and friction, making it easier to hold. The switch 4 is treated with an arc surface to provide a better user experience. A battery pack 7 is arranged in the base 1, and the bottom surface is flat, which can protect the battery pack 7 and can be placed flat on the horizontal ground, thereby protecting the drill bit 5.

[0039] Reference Figure 4 As shown, after pressing the electric drill switch 4, the battery pack 7 installed at the lower part of the electric drill body 6 rotates with the motor 16 and the gear 9 group as the transmission mechanism to drive the electric drill to work, and the PLC integrated circuit component 8 processes the working data of the electric drill and the torque information to make the transmission mechanism output appropriate power. There are several springs 10 on the right side of the motor 16 for collecting torque information and shock absorption, thereby reducing the impact force of the electric drill in the working state. Preferably, the spring 10 is composed of a main spring and 4 small springs surrounding the main spring.

[0040] Reference Figure 2 As shown, a hook 2 is provided on one side of the electric drill, which is used to hang equipment such as a drill bit 5 when the electric drill is in working state and to hang the electric drill body when the electric drill is in idle state.

[0041] Reference Figure 6 As shown, after determining a hole to be drilled, fix the clamp 12 at a certain position, open and rotate the laser emitter 14 upward (or downward), and after reaching the specified scale, observe the point left by the laser on the work surface to determine the next point, thereby realizing the laser positioning function. It should be noted that this electric drill needs to use a drill bit 5 of a certain specification length, otherwise it will affect the positioning accuracy of the drill bit 5.

In order to avoid obscuring the concept of the present application, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed herein.

Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein.
