For example, a first component could be referred to as a second component, and similarly, a second component could be referred to as a first component without departing from the teachings of the utility model. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0025] The terms used herein are for the purpose of describing various embodiments only and are not intended to be limiting. As used herein, the singular is intended to include the plural, unless the context clearly indicates otherwise. It will also be understood that the terms "comprising" and / or "having" when used in this specification specify the presence of a stated feature, number, step, operation, component, element, or combination thereof, and do not preclude the presence or addition of one or more other features, numbers, steps, operations, components, elements, or groups thereof.

[0026] refer to Figures 1 to 4According to a preferred embodiment of the present invention, the front and rear combined multi-head screwdriver has the following structure: Figure 1 As shown, the front-to-back combined multi-head screwdriver includes a rod body 10 and a head assembly 20. The head assembly 20 is detachably arranged at one end of the rod body.

[0027] Specifically, one end of the rod body 10 has a protrusion 11, which is integrally formed with the one end of the rod body 10, and the cross-section of the protrusion 11 is a quadrilateral, wherein one end of the head assembly 20 is detachably provided on the protrusion 11.

[0028] Furthermore, the head assembly 20 includes a connecting head 21, which is detachably provided on the protrusion 11. Specifically, one end of the connecting head 21 has a first mounting groove 2101, and the protrusion 11 is provided in the first mounting groove 2101. At the same time, the end of the rod body 10 provided on the protrusion 11 is fitted with the end of the connecting head 21 provided in the first mounting groove 2101. Since the cross-section of the protrusion 11 is a quadrilateral, when the user rotates the rod body 10, the connecting head 21 rotates synchronously.

[0029] Furthermore, the bottom wall forming the first mounting groove 2101 also has a second mounting groove 2102, and the head assembly 20 also includes a first magnetic block 22, which is fixed in the second mounting groove 2102. The bottom wall forming the second mounting groove 2102 can be adhesively connected to the first magnetic block 22, thereby defining the position of the first magnetic block 22, and the first magnetic block 22 is magnetically connected to the protrusion 11.

[0030] Furthermore, the head assembly 20 also includes a first head 23, which is located at the end of the connector 21 away from the first mounting slot 2101 and is integrally formed with the connector 21. Specifically, the end of the first head 23 away from the connector 21 has a first connection hole 2301. The first connection hole 2301 is configured to mate with an external cutting head. To define the position of the cutting head, the user can optionally install a magnetic block in the first connection hole 2301 to prevent the external cutting head from disengaging from the first connection hole 2301 during use.

[0031] It is worth mentioning that the end of the connecting head 21 having the first head 23 also has two oppositely arranged first mounting holes 101, and each of the first mounting holes 2103 is provided with a second magnetic block 24, wherein the second magnetic block 24 is fixed in the corresponding first mounting hole 2103 by bonding.

[0032] It should be noted that since the above-mentioned protrusion 11 is magnetically connected to the first magnetic block 22, when the user needs to remove the connector 21, he only needs to apply a pulling force to the outer wall of the connector 21, so that the protrusion 11 can be moved away from the first magnetic block 22, and then the connector 21 can be removed.

[0033] Further, if Figure 1 As shown, the surface of the rod body 10 has two knurls arranged opposite to each other, that is, the knurls can increase the friction between the fingers and the surface of the rod body 10, thereby making it easier for the user to rotate the rod body 10.

[0034] Furthermore, the end of the rod body 10 facing away from the head assembly 20 also has a second head 12, and the second head 12 is integrally formed with the rod body 10. It should also be noted that the end of the second head 12 facing away from the rod body 10 also has a second connecting hole 1201, and the size of the second connecting hole 1201 is smaller than the size of the first connecting hole 2301, and the second connecting hole 1201 is configured to cooperate with an external cutting head, that is, the connection method between the external cutting head and the second connecting hole 1201 is consistent with the first connecting hole 2301. It should also be noted that the second head 12 is configured to be inserted into the first connecting hole 2301, that is, the first connecting hole 2301 and the second connecting hole 1201 are both hexagonal, and the cross-sectional shape of the first head 23 and the second head 12 is also hexagonal. Specifically, the user manually disassembles the connecting head 21 to put the first head 23 on the second head 12, and at the same time, the first mounting groove 2101 of the first head 23 is placed outside.

[0035] Specifically, the front-to-back combination multi-head screwdriver also includes a connecting sleeve 30, one end of which is configured to cooperate with the first mounting groove 2101, and the first magnetic block 22 is magnetically connected to the bottom of the connecting sleeve 30, thereby limiting the position of the connecting sleeve 30. In addition, the end of the connecting sleeve 30 facing away from the rod body 10 also has a third connecting hole 301, and the third connecting hole 301 is configured to cooperate with an external cutter head, and the size of the third connecting hole 301 is larger than the size of the second connecting hole 1201. It should also be noted that the end of the rod body 10 with the second head 12 also has two oppositely arranged second mounting holes 102, and each of the second mounting holes 102 is provided with a third magnetic block 40, wherein when the first head 23 cooperates with the second head 12, the two third magnetic blocks 40 respectively cooperate with the two second magnetic blocks 24, thereby limiting the position of the first head 23. It is also worth mentioning that the blade that cooperates with the third connection hole 301 is a sleeve-type blade, that is, the blade is configured to cooperate with a larger external nut, thereby improving the convenience of use of the present invention. It should be noted that compared with traditional screwdrivers, the present invention can be equipped with different types of blades at both ends, thereby improving the convenience of use for users, and when encountering large-sized nuts, the present invention can also be used to remove them, thus having a wider applicability.

[0036] In summary, the front-to-back combination multi-head screwdriver based on the embodiment of the present application is explained, which provides the front-to-back combination multi-head screwdriver with advantages such as ease of use, no need for frequent replacement of blade heads, and high practicality.

[0037] It is worth mentioning that in the embodiments of the present application, the front-to-back combination multi-bit screwdriver has a simple structure, does not involve complex manufacturing processes and expensive materials, and is highly economical. Furthermore, for manufacturers, the front-to-back combination multi-bit screwdriver provided in the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further promoting product promotion and use.
