Description

Technical Field

[0001] This application relates to the field of multi-functional tool technology, and more particularly to a keychain and a keychain set. Background Technology

[0002] Screwdrivers, as one of the most basic and widely used fastening tools, are a staple item in homes and workplaces, used to tighten or loosen screws of various sizes.

[0003] Traditional screwdrivers typically come in single units or as part of a tool set, designed primarily to meet fixed, predictable repair needs. However, this traditional form of screwdriver reveals significant limitations when dealing with sporadic repair needs in unexpected, mobile scenarios. Specifically, when users are in non-fixed workplaces such as offices, outdoors, or while traveling, they may encounter unexpected situations such as loose eyeglass screws, needing watch adjustments, loose USB device interface screws, or loose battery compartment screws on children's toy cars. Although the repairs themselves are simple, users usually don't carry traditional screwdrivers with them, leading to a dilemma of "having the tools at home, but being unable to solve the immediate problem."

[0021] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] like Figure 1 and Figure 2 As shown, the keychain 100 provided in this application embodiment includes a main body 110 and a movable latch 120 connected to the opening of the main body 110. The movable latch 120 is rotatably connected to one end of the opening of the main body 110, closing or opening the opening. The main body 110 and the movable latch 120 enclose each other to form a key ring. A key or hanging ring 211 can be installed into the key ring when the movable latch 120 is open.

[0024] In this embodiment, the main body 110 is provided with a bit insertion hole 111, which is located on the circumferential side of the main body 110. The bit insertion hole 111 is configured to insert a bit 300, and the head of the bit 300 inserted into the bit insertion hole 111 extends to the outside of the main body 110. That is to say, the keychain 100 provided in this embodiment has the function of removing and installing screws after inserting the bit 300. Since the keychain 100 is an item that people carry with them in daily life, the bit insertion hole 111 on the keychain 100 allows users to carry an emergency screwdriver, thereby meeting the user's daily needs for removing and installing screws.

[0025] For example, the bit insertion hole 111 is located at the corner of the circumferential side of the main body 110, and the thickness of the bit insertion hole 111 at the corner is greater than the thickness of other parts of the main body 110. This allows for a reduction in the thickness of other parts, making the keychain 100 thinner and lighter overall.

[0026] In some embodiments of this application, the axial direction of the bit insertion hole 111 extends along the length of the body 110. During use, the user can hold the key ring 100, using it as the handle portion of the bit 300 for easy application of force.

[0027] In some embodiments of this application, the circumferential edge of the body 110 is provided with one or more of the following: a file, a ruler 112, a nail puller, and a bottle opener 113. Exemplarily, the body 110 has opposing first side 130 and third side 150, and opposing second side 140 and fourth side 160, the second side 140 and fourth side 160 being located between the first side 130 and the third side 150. The main body 110 has a file, ruler 112, nail puller, and bottle opener 113 on its circumferential edge. The file (not shown) is located on one of the first side 130 and the third side 150, the bottle opener 113 is located on the other side, the ruler 112 is located on one of the second side 140 and the fourth side 160, the movable latch 120 is located on the other side, the bit insertion hole 111 is located at the corner connecting the first side 130 and the fourth side 160, and the nail puller is located at the corner connecting the first side 130 and the second side 140. This arrangement gives the keychain 100 multiple functions, allowing it to be used as a file, ruler 112, nail puller, and bottle opener 113 while holding keys, facilitating daily emergency operations for users.

[0028] This application embodiment also provides a keychain 100 set, which includes a quick-change bit adapter 200 and a keychain 100 according to any of the above-described embodiments. The quick-change bit adapter 200 has a connecting end 210 and a mounting end 220. The connecting end 210 is detachably connected to the keychain 100, and the mounting end 220 is provided with a quick-change bit structure, which is configured to detachably mount bit 300. That is, the keychain 100 is equipped with a quick-change bit adapter 200, which detachably mounts bit 300. When not in use, bit 300 is stored on the quick-change bit adapter 200. When in use, it is removed from the quick-change bit adapter 200 and then installed in the bit insertion hole 111 for use as a screwdriver. After use, bit 300 is removed and placed back on the quick-change bit adapter 200. The number of quick-change bit connectors 200 can be one or more (including two). Multiple quick-change bit connectors 200 can store multiple bits 300 of different specifications and models to meet different user needs.

[0029] For example, the connecting end 210 is provided with a hanging ring 211, and the quick-change bit connecting rod 200 is installed in the key ring formed by the main body 110 and the movable latch 120 through the hanging ring 211. The quick-change bit structure is set as a quick-change bit chuck structure. For example, the quick-change bit chuck structure is the quick-change chuck structure of the head of an electric screwdriver, that is, a quick-change chuck structure that includes a spring steel ball locking structure.
