The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0030] like Figure 1 , Figure 2As shown, the utility model provides a small screwdriver, including a housing 11 and a scanning sensor component, a tool head storage component and a pressing component arranged inside the housing 11.

[0031] The scanning sensor assembly includes a photoelectric scanner 22 and a photoelectric sensor 21 connected to the photoelectric scanner 22. In a specific implementation, a hole is opened on the outer wall of the housing 11 to form a scanning window, which faces the photoelectric scanner 22, so that the photoelectric scanner 22 can scan the screw to be scanned through the scanning window.

[0032] The tool bit storage assembly includes a rotating shaft 33 fixed on the inner wall of the housing, a turntable rotatable around the rotating shaft 33 , and a dial wheel for controlling the rotation of the turntable, wherein the dial wheel is connected to the photoelectric sensor 21 .

[0033] In this embodiment, the rotating disk includes a first rotating disk 31 and a second rotating disk 32. The first rotating disk 31 is provided with a first groove meshing with the first dial 34, and the second rotating disk 32 is provided with a second groove meshing with the second dial 35. The photoelectric sensor 21 is connected to a first driver (not shown in the figure) of the first dial 34 and a second driver (not shown in the figure) of the second dial 35, and can control the number of rotations of the first dial 34 and the second dial 35.

[0034] In one embodiment of the present application, the structure of the first dial wheel 34 and / or the second dial wheel 35 is as follows: Figure 3 As shown, it includes a rotating lever 61 and an eccentric wheel 62 fixed on the rotating lever 61, wherein the rotating lever 61 is connected to the first driver or the second driver, and the first driver or the second driver can drive the rotating lever 61 to rotate around its own axis. The first rotating disk 31 is provided with a circle of first grooves 63, and the second rotating disk 32 is provided with a circle of second grooves 64. The first grooves 63 and / or the second grooves 64 are formed by a plurality of arc groove monomers arranged and connected along the circumferential direction. The eccentric wheel 62 is located in the first groove 63 and cooperates with the arc groove monomer. Through the cooperation of the eccentric wheel 62 and the first groove 63, the eccentric wheel can not only provide the rotation of the first rotating disk 31 and / or the second rotating disk 32 but also realize precise positioning.

[0035] In another embodiment of the present application, the first dial wheel 34 and / or the second dial wheel 35 include a rotating dial rod and a bevel gear fixed on the rotating dial rod. In this case, the first groove provided on the first rotating disk 31 and / or the second groove provided on the second rotating disk 32 are bevel teeth meshed with the bevel gear. It should be noted that the first dial wheel 34 and the second dial wheel 35 can adopt different structures.

[0036] Of course, it is also feasible to have only one turntable. In this case, that is, the turntable only includes one of the first turntable and the second turntable, and the dial wheel can be adapted to the turntable structure adopted by the dial wheel.

[0037] In specific implementation, when a corresponding cutter head is matched, if the cutter head is in the first wheel disc 31, the first dial wheel 34 is controlled to dial the first turntable 31 for a corresponding number of times (the number of times is counted according to the special part of the wheel disc structure as the first, and counted clockwise), driving the first turntable 31 to rotate to the corresponding position. If the cutter head is in the second wheel disc 32, the second dial wheel 35 is controlled to dial the second turntable 32 for a corresponding number of times (the counting method is the same as the first wheel disc).

[0038] The pressing assembly includes a locking mechanism 41 and an operating rod 43 connected to the locking mechanism 41, wherein the operating rod 43 matches the size of the cutter head position of the first rotating disk 31, and when the first rotating disk 31 or the second rotating disk 32 rotates, the cutter head positions on the first rotating disk 31 or the second rotating disk 32 will align with the operating rod 43 one by one. A magnet can be provided at the end of the operating rod 43 for contacting the cutter head to better absorb the cutter head, and the front end of the housing 11 has a cutter exit for extending the cutter head, which is opposite to the operating rod 43, and a spring 15 can be provided at the end of the cutter exit to provide a buffer for the extended cutter head.

[0039] In order to prevent the operating rod 43 from being laterally displaced, a positioning tube 44 may be provided on the outer side of the operating rod 43 , and the positioning tube 44 is fixed on the inner wall of the housing 11 .

[0040] The locking mechanism 41 is the same as the locking mechanism of the ballpoint pen in the prior art, including upper and lower tooth columns, the upper tooth column is pressed by hand, and the lower tooth column can rotate internally, the meshing of the upper and lower tooth columns is incomplete, only the tooth tips are partially meshed, and the guide ribs behind the two meshed teeth are designed to slide in the same guide groove, and after the lower tooth column slides out of the guide groove under the push of the upper tooth column, due to the action of the spring, the teeth of the lower tooth column will slide along the inclined surface of the teeth of the meshing upper tooth column, so that under the action of the inclined surface, the lower tooth column will turn an angle, slide to the other side, and be pressed down, and the function of press locking can be achieved by repeating this process.

[0041] One end of the locking mechanism 41 is connected to a button disposed outside the shell, and the other end is connected to an operating rod 43. The button can be disposed on the top or side wall of the shell 11. The locking mechanism 41 is activated by manually pressing the button to realize the up and down movement of the operating rod 43.

[0042] Please also refer to Figure 4 and Figure 5In this embodiment, the first rotating disk 31 has a fixed cutter head position 37, which is used to place a special structure 39. The fixed cutter head position 37 is not allowed to be replaced, and one of the cutter heads adjacent to the fixed cutter head position 37 is an empty cutter head position 38. The special structure 39 is provided with a through hole through which an operating rod can pass, so that the operating rod can pass through to select the cutter head of the second wheel. In this embodiment, the cross section of the through hole is a pentagon.

[0043] The second rotating disk 32 has the same structure as the first rotating disk 31, and also has a fixed cutter head position and an empty cutter head position. If a cutter head in the first rotating disk 31 is selected, the operating rod directly selects the cutter head and directly passes through the empty cutter head position of the second rotating disk.

[0044] In another embodiment of the utility model, only a fixed tool head position can be set on the first rotating disk 31, and an empty tool head position can be set on the second rotating disk. When there is only one rotating disk, the fixed tool head position and the empty tool head position can be not set.

[0045] In specific implementation, the battery can be used for power supply. In this embodiment, the battery 14 is arranged in the housing 11. The upper end of the housing 11 is provided with a pressing head 13, and a contact point is arranged under the pressing head 13. When the pressing head 13 is pressed, the photoelectric sensor system opens a passage and starts scanning. When the pressing head 13 is disconnected, the system is powered off and does not work.

[0046] The small screwdriver provided by the utility model integrates a scanning sensor component, a tool head storage component and a pressing component in a housing. The scanning sensor component can quickly identify the device screw model, and efficiently match the corresponding screwdriver in the tool head storage component. Finally, the pressing component is used to extend the matched tool from the housing. The small screwdriver provided by the utility model can easily and quickly identify and match screw props, especially in some special scenarios, such as places that cannot be reached by human hands, accurately identify the device screw model and efficiently match the corresponding screwdriver, greatly improving work efficiency.
