Example 1

The embodiment provides a manual screwdriver which is used for screwing and disassembling screws. Please refer to fig. 1 and 2. The manual screwdriver comprises a handle 12, a bracket 13 and a cutter bar 11. Wherein the cutter bar 11 is coaxially arranged at one end of the handle 12. The handle 12 is defined to have one end of the cutter bar 11 as a front end and the opposite end as a rear end. The bracket 13 is disposed at the front end of the handle 12, the cutter bar 11 includes a connection end 114 for connecting the bracket 13, the connection end 114 is fixedly disposed through the bracket 13 and the bracket 13, and the other end (also called as distal end) opposite to the connection end 114 is a working end for screwing a screw.

In this embodiment, the working end of the tool bar 11 includes a mounting seat 112 for insertion of the bits 20. The mounting base 112 has a hollow mounting cavity, and the mounting end of the screwdriver bit 20 is correspondingly inserted into the mounting cavity to realize non-rotating connection. The installation cavity is a hexagonal column cavity, and the installation end of the corresponding batch head is a hexagonal column.

In a specific use scene, the screwdriver head is divided into a plurality of different specifications according to the structure of the working head, and one type of screw is screwed on the screwdriver head of each specification. The mounting base 112 can select to mount the screwdriver head corresponding to the matched specification according to the specification of the screw to be screwed. Typically, a manual screwdriver is provided with a plurality of different types of bits for selection by a user to drive a plurality of different types of screws. These bits are often stored separately and, due to the small size of the bits, are easily lost when stored separately from the manual screwdriver, often resulting in a bit that is not found.

In view of this, as shown in connection with fig. 2 and 3, the support 13 is provided with a plurality of storage structures 132 for storing the batch heads, the plurality of storage structures 132 being arranged around the axis of the cutter bar 11. When the storage structure 132 of the support 13 is full of the bits 20, the bits 20 are circumferentially wound around the axis of the cutter bar 11. The storage structure 132 enables the manual screwdriver to store the screwdriver bit 20, so that the screwdriver bit 20 and the manual screwdriver can be stored integrally.

The axis of the cutter bar 11 is understood to be a straight line extending coaxially with the cutter bar 11 and passing through the center of the cutter bar 11.

Referring to fig. 2, the storage structure 132 of the bracket 13 stores the bits 20, and the bits 20 are wrapped around the outer circumference of the virtual extension of the connection end 114 of the cutter bar 11. In other embodiments, one end of the knife bar 11 may extend partially into the center of the storage structure 132 or may extend through the center of the storage structure 132. When one end of the cutter bar 11 penetrates through the center of the storage structure 132, the storage structure 132 surrounds the outer circumference of the end of the cutter bar 11.

The screwdriver head and the screw are usually iron structures and can be attracted magnetically. As shown in fig. 3, the bracket 13 is further provided with a mounting structure 130 for mounting the magnetic ring 15, the mounting structure 130 and the storage structure 132 are adjacent to each other in the axial direction, and after the magnetic ring 15 is mounted on the mounting structure, the magnetic ring 15 and the cutter bar 11 are coaxially arranged, and the magnetic ring 15 is located on the adjacent side of the storage structure. After the batch head 20 is stored in the storage structure 132, the tail end of the batch head 20 is adjacent to the magnetic ring 15, and the magnetic ring 15 can absorb the batch head, so that the risk that the batch head 20 falls off from the storage structure 132 is reduced. Moreover, the magnetism of the magnetic ring 15 can be used for adsorbing the screws scattered on the table top, and the magnetic ring 15 can actively adsorb and temporarily store the screws under the condition that the screws are small and inconvenient to pick up, so that the risk of scattering and losing the screws is reduced.

In order to facilitate the adsorption of the screws, the magnetic ring 15 is partially exposed, so that the outer side surface of the magnetic ring 15 can be directly contacted and adsorbed with scattered screws, and the stability of adsorbing and storing the screws is improved. Specifically, referring to fig. 2 and 3, a mounting structure 130 is disposed at the front end of the bracket 13, and the mounting structure 130 is configured as a groove structure formed by connecting the bracket 13 to the outer end surface of the cutter bar 11. The groove structure surrounds the circumference of the tail end of the cutter bar 11, the magnetic ring 15 is arranged behind the groove structure, and the cutter bar 11 penetrates through the center hole of the magnetic ring 15 to be fixedly connected with the bracket 13. The outer (front) end surface of the magnetic ring 15 is exposed, and a tiny screw can be directly adsorbed on the outer end surface of the exposed magnetic ring 15 and surrounds the circumference of the proximal end of the cutter bar 11.
