Description

Technical Field

[0001] This utility model relates to the field of electric drill technology, and in particular to an electric drill equipped with a manual lock. Background Technology

[0002] An electric drill is a drilling tool that uses electricity to power holes. It is a conventional product among power tools and also the power tool product with the largest demand. The working principle of an electric drill is that the rotor of a small-capacity electromagnetic rotary or electromagnetic reciprocating motor performs work by cutting through a magnetic field. Through the transmission mechanism, it drives the working device, which in turn drives the gears to increase the power of the drill bit, thereby enabling the drill bit to scrape the surface of the object and better penetrate it.

[0003] The inventors of this application have discovered the following problems during practical use: Currently, manual lock electric drills require the manual lock to be opened before the drill bit can be inserted. However, because the manual lock lacks a mechanism to secure the drill bit, the drill bit may slip out of the manual lock during installation, affecting installation efficiency.

[0004] Therefore, it is necessary to provide an electric drill equipped with a manual lock to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem this invention aims to solve is that the drill bit may slip out of the manual lock during installation, affecting installation efficiency. In view of the above-mentioned defects of the prior art, this invention provides an electric drill equipped with a manual lock.

[0006] To achieve the above objectives, the technical solution of this utility model is: an electric drill equipped with a manual lock, comprising an electric drill body, a manual lock mechanism provided on the front side of the electric drill body, the manual lock mechanism comprising a manual lock body, a slot provided on the front side of the manual lock body, a rubber sleeve engaged inside the slot, and an insertion hole provided on the front side of the rubber sleeve.

[0007] By adopting the above technical solution, a slot is set in the manual locking mechanism, and a rubber sleeve is engaged inside the slot, providing a stable and easy-to-install fixing method for the drill bit. This increases friction, prevents the drill bit from slipping during installation, and effectively fixes the drill bit through its elastic properties.

[0008] In a further configuration, a hammer plate is connected to the rear side of the electric drill body via a connecting mechanism, the connecting mechanism including an extension rod.

[0009] By adopting the above technical solution, and by setting a connecting mechanism and connecting a hammer plate on the rear side of the drill body, the functionality of the drill is expanded. The introduction of the hammer plate allows users to directly use the drill as a hammer when they need hammering assistance, without having to carry additional tools, thus improving work efficiency and portability.

[0010] Furthermore, one end of the extension rod is fitted with a first magnet, and four extension rods are provided.

[0011] By adopting the above technical solution, the first magnet is embedded at one end of the extension rod, making the connection between the hammer plate and the electric drill body more convenient and firm. The magnetic force of the first magnet enables the hammer plate to be quickly and stably attached to the electric drill body, improving the efficiency and convenience of installation.

[0012] Furthermore, a receiving post is provided at the relative position of the connecting mechanism, and a second magnet is embedded inside the receiving post.

[0013] By adopting the above technical solution, a support column is set at the relative position of the connecting mechanism, and a second magnet is embedded inside the support column, providing a stable support point for the hammer plate. The interaction between the second magnet and the first magnet makes the hammer plate more secure and stable when connected, avoiding detachment or loosening due to vibration or impact.

[0014] Furthermore, a top shoulder is provided on one side of the card slot, which is used to provide support.

[0015] By adopting the above technical solution, a top shoulder is provided on one side of the slot to provide additional support for the rubber sleeve. This helps to prevent the rubber sleeve from being difficult to install due to uneven force during the installation of the drill bit, thereby extending its service life.

[0016] Furthermore, the rubber sleeve is designed in a conical shape, and a hook is provided at one end of the rubber sleeve.

[0017] By adopting the above technical solution, the conical structure of the rubber sleeve makes it easier to align with the insertion hole when installing the drill bit and smoothly slide it into place, improving the convenience and accuracy of installation and reducing installation errors or damage caused by improper operation.

[0018] Furthermore, a protruding portion is provided at the middle position of the rubber sleeve, and the protruding portion is arranged in an arc shape.

[0019] By adopting the above technical solution, the protrusion in the middle of the rubber sleeve is designed with an arc shape, which helps to increase the pressing pressure between the rubber sleeve and the user.

[0020] Compared with related technologies, the electric drill equipped with a manual lock provided by this utility model has the following beneficial effects: This utility model provides an electric drill equipped with a manual lock. By setting the drill body and the manual lock mechanism, the drill body provides a stable power output and control platform, enabling users to easily perform drilling operations. In traditional electric drills, the drill bit may fall off during installation when changing drill bits. With the manual lock mechanism, users can easily pre-fix the drill bit to the drill body without additional tools or complicated steps, saving time and reducing the difficulty of operation, allowing even beginners to install it quickly.

[0021] This utility model provides an electric drill equipped with a manual lock, which uses a rubber sleeve and a protrusion on the top. The protrusion on the rubber sleeve further improves the fixing effect of the drill bit. The protrusion allows the rubber sleeve and the drill bit to generate a tension, thereby enhancing the fixing effect and making the drill bit more secure and less prone to shaking during installation.

[0027] like Figure 1 and Figure 5 As shown, a first magnet 302 is fitted into one end of the extension rod 301. There are four extension rods 301. The four extension rods 301 further enhance the stability and firmness of the connection, making it less likely for the hammer plate 4 to fall off or loosen during the striking operation, thereby ensuring the safety and reliability of the operation.

[0028] like Figure 1 and Figure 5 A receiving column 5 is provided at the relative position of the connecting mechanism 3. A second magnet 6 is embedded inside the receiving column 5. This magnetic connection method not only simplifies the installation steps, but also improves the convenience of disassembly, so that users can quickly remove the hammer plate 4 when needed and easily reinstall it.

[0029] like Figure 1 and Figure 6 As shown, a top shoulder 204 is provided on one side of the card slot 201. The top shoulder 204 is used to provide support. The presence of the top shoulder 204 also enhances the overall structural strength of the manual locking mechanism 2, enabling it to maintain reliability for a long time.

[0030] like Figure 2 and Figure 6 As shown, the rubber sleeve 202 has a conical structure. One end of the rubber sleeve 202 is provided with a hook 205. The hook 205 at one end of the rubber sleeve 202 further enhances its fixing effect. The hook 205 can engage with the slot 201 to form a fixed shape, preventing the rubber sleeve 202 from falling off or loosening during use, thereby ensuring the stability and safety of the drill bit installation.

[0031] The implementation principle of this utility model is as follows: First, prepare the drill bit, accurately insert the rubber sleeve 202 into the slot 201 in the manual locking mechanism 2, align the front end of the drill bit with the insertion hole 203 at the front end of the rubber sleeve 202, and insert it smoothly.

After the drill bit is fully inserted, operate the manual locking mechanism 2 to rotate it from the open state to the locked state, thereby ensuring that the drill bit is firmly fixed on the electric drill body 1. The tight fit of the rubber sleeve 202 helps to prevent the drill bit from slipping during installation and plays a dustproof and sealing role, preventing dust and debris from entering the interior of the manual locking mechanism 2 and protecting the internal mechanical structure from damage. When hammering assistance is needed, a magnetically connected hammer plate 4 can be installed on the connecting mechanism 3 at the rear of the drill body 1. The hammer plate 4 is connected by magnetic attraction, which makes it easy to quickly pick up and store. Use the hammer plate 4 to perform necessary hammering operations, and then disassemble and recycle it after completion.

[0032] Example 2: like Figure 6 As shown, based on Embodiment 1, this utility model provides a technical solution: a protruding part 7 is provided at the middle position of the rubber sleeve 202. The protruding part 7 is arranged in an arc shape. The arc shape of the protruding part 7 can better install the drill bit, thereby improving the accuracy and adaptability of the installation.

[0033] In practice, when inserting the drill bit, by pressing the protruding part 7, the rubber sleeve 202 can protrude outward, and then the drill bit is inserted. When the hand is released, the drill bit can have a pulling force, which further presses it into the manual lock body 206, thus improving the locking effect.

[0034] The advantages of this technical solution in practical applications include, but are not limited to, the following: 1. With the manual locking mechanism, users can easily pre-fix the drill bit to the drill body without additional tools or complicated steps, saving time; 2. The protrusions on the rubber sleeve further enhance the fixing effect of the drill bit, making the drill bit more secure during installation.
