Description

Technical Field

[0001] This utility model belongs to the field of electric screwdrivers, and in particular relates to a multifunctional electric screwdriver. Background Technology

[0002] To enable manual operation of existing commercially available electric screwdrivers without batteries, two metal components and six metal rods must be added to the outside of the drive shaft. This increases the length of the drive shaft and the body, thus increasing costs.

[0003] While commercially available manual ratchet screwdrivers are faster to use than manual screwdrivers, their two-piece metal design results in higher costs and insufficient concentricity of the drive shaft, making them unsuitable for use with electric screwdrivers.

[0004] In view of this, it is indeed necessary to improve the above-mentioned shortcomings. This utility model has a simple structure, small size, and is easy to process and manufacture. It also has the function of a ratchet screwdriver, making it more convenient to use and lower in cost. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-functional electric screwdriver that is small in size, light in weight, has a stable structure, and also functions as a ratchet screwdriver, making it easy to operate.

[0006] To achieve the above objectives, the specific technical solution of this utility model for a multifunctional electric screwdriver is as follows: Includes: a main body with two battery spring slots, two main body screw holes, a main body ratchet hole, a main body shaft hole, a main body flange, a main body positioning groove, a main body accommodating space, and a main body limiting flange; a drive shaft component with a drive shaft internal hexagonal hole, a drive shaft ratchet groove, a drive shaft limiting groove that engages with a C-lock, a drive shaft elastic groove that engages with a disc elastic component, and a drive shaft hexagonal flange at the other end that engages with the internal hexagonal hole of the shaft disc component; and a shaft disc component with a shaft disc component internal hexagonal hole that engages with the drive shaft hexagonal flange, and a shaft disc component with three shaft disc teeth at the other end. The gearbox engages with a planetary gear; a ratchet assembly has a ratchet disc and a ratchet bar with a groove for engaging with a ratchet elastic element, and a ratchet bar flange plane and a ratchet bar flange inclined surface for engaging with the drive shaft ratchet groove; a disc assembly has two inner flanges engaging with a disc positioning flange and a disc hole engaging with the body, and an outer disc recess and an outer disc flange engaging with the ratchet disc; a disc elastic element, one end engaging with the drive shaft elastic groove and the other end engaging with the body; a tooth A gearbox assembly includes an internal gear that mates with a planetary gear, a space within the gearbox that mates with a bushing, and a flanged hole that mates with a ratchet bar. Two external gearbox recesses mate with a motor mounting component. A bushing assembly has an internal hole that mates with a drive shaft, and a flange with a flanged hole that mates with a ratchet bar. A switch assembly has a circular hole that mates with a rocker switch. A switch mounting component has a flange that mates with a motor recess. One switch fixing groove mates with a rocker switch, and two switch fixing circular grooves mate with the main body; one motor component has a motor gear mates with a planetary gear, and a motor groove mates with a switch fixing flange; one motor fixing component has two motor fixing flanges at one end that mate with a gearbox component groove, and a motor fixing circular hole at the other end that mates with the motor component; one main body rear cover has two main body rear cover screw holes that mate with the main body screw holes; and one battery cover has a battery cover screw hole that mates with the main body battery screw hole.

[0007] Furthermore, when the motor rotates, it drives the planetary gear to rotate, which in turn drives the drive shaft to rotate, thereby achieving the purpose of tightening or loosening the screw.

[0008] Furthermore, when the disc is in its normal position, it is in electric operation mode. The ratchet disc is at its highest point in the y-axis direction. The plane of the ratchet disc's round bar flange and the inclined surface of the ratchet disc's round bar flange are disengaged from the ratchet groove of the drive shaft. The hexagonal flange of the drive shaft is coupled with the hexagonal hole inside the disc. When the motor rotates, it drives the drive shaft to rotate to lock or loosen the screw.

[0009] Furthermore, when the disc is rotated 90 degrees to this position, it operates in ratchet mode. Due to the push of the ratchet elastic element, the ratchet disc is at its lowest point in the y-axis direction. The plane of the ratchet bar flange and the inclined surface of the ratchet bar flange engage with the ratchet groove of the drive shaft, giving the drive shaft ratchet function. When the plane of the ratchet bar flange is in front and the inclined surface of the ratchet bar flange is behind, the drive shaft can only move backward and not forward. When the plane of the ratchet bar flange is behind and the inclined surface of the ratchet bar flange is in front, the drive shaft can only move forward and not backward. Due to the engagement of the inner flanges of the two discs with the body flange and the push of the disc elastic element, the drive shaft is at its highest point in the x-axis direction, causing the hexagonal flange of the drive shaft to disengage from the inner hexagonal hole of the shaft disc. At this time, even if the motor rotates, it cannot drive the drive shaft to move. Only the manual ratchet screwdriver function is activated. Attached Figure Description

[0014] The above describes the structural configuration and connection relationships of this utility model. The method of using this utility model is as follows: For a simplified description of the operation of this utility model, please refer to Figures 1 to 8. The rotation of the motor component 20 drives the planetary gear 25 to rotate, which in turn drives the shaft disk component 12 to rotate. The hexagonal hole 121 inside the shaft disk component engages with the hexagonal flange 115 of the drive shaft, thereby driving the drive shaft component 11 to rotate, thus locking or loosening the screw.

[0015] In a preferred embodiment, when the disc component 14 is in the normal position, it is in electric function mode. The ratchet disc 131 is pushed by the outer flange 145 of the disc component and is at the highest point in the y-axis 33 direction, so that the plane 134 of the ratchet bar flange and the inclined surface 135 of the ratchet bar flange are disengaged from the ratchet groove 112 of the drive shaft. The hexagonal flange 115 of the drive shaft is coupled with the hexagonal hole 121 of the shaft disc component. When the motor component 20 rotates, it drives the drive shaft component 11 to rotate, which is used to lock or loosen the screw.

[0016] In a preferred embodiment, when the disc component 14 is rotated 90 degrees to this position, it is in ratchet function mode. At this time, the ratchet elastic element 27 pushes the ratchet component disc 131 to the lowest point in the y-axis 33 direction, so that the ratchet component round bar flange plane 134 and the ratchet component round bar flange inclined surface 135 cooperate with the drive shaft ratchet groove 112, so that the drive shaft component 11 has ratchet function. When the ratchet component round bar flange plane 134 is in front and the ratchet component round bar flange inclined surface 135 is behind, then the drive shaft component 11 can only move backward and cannot move backward. When moving forward, with the ratchet component's round bar flange plane 134 at the rear and the ratchet component's round bar flange inclined surface 135 at the front, the drive shaft component 11 can only move forward and cannot move backward. Due to the cooperation between the inner flange 141 of the two disc components and the body flange 105, as well as the pushing of the disc elastic component 15, the drive shaft component 11 is at the highest point in the x-axis 32 direction. The drive shaft's hexagonal flange 115 disengages from the inner hexagonal hole 121 of the shaft disc component. At this time, even if the motor component 20 rotates, it cannot drive the drive shaft component 11 to move. Only the manual ratchet screwdriver function can be activated.

[0017] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
