The double-headed screwdriver has a novel structure, and the handle and the shank are detachable and separable, replacing the existing shank and handle as an integrally formed structure, which is convenient for separate replacement and flexible and convenient.

[0007] Furthermore, the handle is provided with a fixing through hole for the fastener to pass through, the fixing through hole is communicated with the accommodating groove, and the knife rod is provided with a threaded groove that cooperates with the fastener to connect reliably, is not easy to loosen freely, and is convenient for disassembly and assembly. The handle and the knife rod are separable for easy and separate replacement, which is flexible and convenient.

[0008] Furthermore, a fixing groove is provided on the handle, a fixing through hole is provided in the fixing groove, and the end of the fastener is located in the fixing groove but does not protrude from the handle, thereby avoiding damage caused by impact and affecting subsequent disassembly and assembly, thereby playing a simple protective role.

[0009] Furthermore, the accommodating groove includes a first groove and a second groove, the first groove is connected to the second groove, the cross-sectional diameter of the first groove is larger than the cross-sectional diameter of the second groove, the first groove corresponds to the end of the tool rod, and the second groove corresponds to the blade head of the tool rod. During the assembly process, when the end of the tool rod abuts against the end of the first groove, the blade head of the tool rod is located in the second groove, and the fixing through hole is aligned with the threaded groove, thereby facilitating the installation of the fastener and reducing the difficulty of installation.

[0010] Furthermore, a screwdriver is provided at the tail of the handle, and the provision of the screwdriver makes it convenient for the user to pry some small parts, thus enriching the usage functions.

[0011] Furthermore, an anti-skid rubber sleeve is provided on the handle to improve the anti-skid performance, making it less likely to slip and easier to apply force.

[0012] Furthermore, the anti-skid rubber sleeve is provided with an anti-skid groove, which increases the roughness of the surface of the anti-skid rubber sleeve, thereby improving the friction, making it less likely to slip and more reliable to use.

[0013] Furthermore, both ends of the tool rod are provided with magnetic tool heads, which are easy to operate through magnetic adsorption screws. Both tool heads can be used, and the utilization rate is high.

[0014] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0015] The handle and the knife bar are detachable and separate, replacing the existing knife bar and handle as an integrally formed structure, which is convenient for separate replacement and flexible and convenient. During assembly, the knife bar is first extended into the accommodating groove from the limiting opening, and then the fastener is inserted into the fixed through hole and connected with the threaded groove, so that the fastener locks the knife bar, the screw connection is reliable, and it is not easy to loosen freely. The limiting opening limits the radial shaking of the knife bar, and the fastener limits the horizontal movement of the knife bar. It is restricted in multiple directions, which ensures the stability of the knife bar. The knife bar can be taken out by loosening the fastener.

[0016] During the assembly process, when the end of the shank is against the end of the first slot, the cutter head of the shank is located in the second slot, and the fixed through hole is aligned with the threaded groove, thereby facilitating the installation of the fastener and reducing the difficulty of installation.
