The two sides below the base 11 are provided with fixing pieces 4, and the fixing pieces 4 can adopt sucking discs, magnetic attraction mechanisms and the like so as to avoid the displacement of the device in the drilling process.
The positioning mechanism 12 comprises lifting slide rails 121 symmetrically arranged at the left end and the right end of the base 11, positioners 122 arranged at the upper end and the lower end of the lifting slide rails 121, lifting slide rods 123 matched with the sliding connection between the lifting slide rails 121, lifting springs 124 arranged between the lifting slide rods 123 and the lifting slide rails 121, and numerical marks 125 arranged on the surfaces of the lifting slide rails 121. The positioner 122 may employ a bolt positioner that is clamped in place at different locations by rotating an adjusting bolt shaft.
The drilling mechanism 2 includes a bit holder 21 fitted on the elevating slide bar 123, a bit 22 fitted on the lower end of the bit holder 21, and an electric hand drill 23 fitted on the upper end of the bit holder 21. The bit holder 21 may be a high strength drill chuck for use in connection with the means for connecting the drill bit to the drill and for positioning and guiding.
The front and rear ends of the base 11 are respectively provided with a through groove 111, a limiting slide rail 112 is arranged above the through groove 111, and rotary seats 113 are respectively arranged on two sides of the through groove 111. The rotating seat 113 is a structural member capable of rotating on a certain axis for supporting and allowing the other member to rotate, and the rotating seat 113 may employ a rolling bearing (such as a ball bearing or a roller bearing) or a sliding bearing.
The limiting mechanism 31 comprises a positive and negative screw rod 311 arranged on the through groove 111, limiting sliding blocks 312 matched and arranged on the left and right rods of the positive and negative screw rod 311, a stop block 313 arranged on the outer side of the limiting sliding blocks 312, and a rotating frame 314 rotatably arranged at the lower end of the limiting sliding blocks 312. The limit slider 312 is a ball nut member that cooperates with the positive and negative thread screw 311, and is internally provided with threads and balls. The positive and negative lead screw 311 is a special lead screw that is commonly used to synchronize or adjust the relative position between two or more components.

Bearings can be adopted between the fixed blocks 321 and the transmission rods 322 to realize rotation installation.
Example 2

(1) Preparation:
firstly, marking and positioning holes to be processed on a workpiece, and placing the electric hand drill positioning and drilling device on a stable working table. Ensuring that all components are already fixed and ready.
(2) Positioning a workpiece:
In the case of a planar workpiece, the rotating frame 314 is ensured to be rotated and folded into the through groove 111.
If the workpiece is a cylindrical workpiece, the rotating frame 314 is opened, the transmission mechanism 32 is operated through the rotating handle 323 according to the diameter of the workpiece, and the positive and negative screw rods 311 on two sides are controlled to synchronously rotate, so that the synchronous movement of the limit sliding blocks 312 is realized, and the rotating frame 314 correspondingly stretches to a proper position so as to fix the workpiece.
The workpiece is placed on the base 11 and stabilized by the rotating frame 314.
(3) Positioning a drill bit:
The height of the lifting slide bar 123 is adjusted according to the position of the hole to be drilled on the workpiece, so that the drill 22 is aligned with the scribing position of the predetermined hole. Numerical indicia 125 on the lifting slide 121 may assist the user in accurately determining the position of the drill bit 22.
(4) Starting drilling:
Ensuring that both the workpiece and the drill 22 are stably secured. The electric hand drill 23 is turned on and the drilling operation is started.
(5) Ending operation:
After the drilling is completed, electric hand drill 23 is first turned off. The work piece is carefully released, ensuring that no harm or damage is caused. If the drilling of other workpieces is needed, repeating the steps.
(6) Cleaning and storing:
after all drilling operations are completed, any debris or dust on the device is cleaned. The device is stored in a dry, clean place for the next use.
Through the operation method, a user can efficiently and accurately use the electric hand drill to position the drilling device for drilling.
