Detailed Description
The present invention will be further illustrated by the following specific examples, which are carried out on the premise of the technical scheme of the present invention, and it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.
As shown in the attached drawings, the multifunctional telescopic double-head screwdriver comprises a handle 7, wherein the handle 7 is respectively connected with a straight screwdriver 1 and a cross screwdriver 6, a straight lifting pull rod 2 is arranged in the handle 7, the straight lifting pull rod 2 comprises a pull rod inner slide rod 2-1 and a pull rod outer toothed rod 2-3, the pull rod inner slide rod 2-1 is sleeved with a pull rod outer toothed rod 2-3, a lock hook plate 2-6 and a lock spring b 2-8 are arranged on the pull rod inner slide rod 2-1, a lock pin 2-2 is arranged on the lock hook plate 2-6, a nylon slide block 2-5 is connected at the lock hook plate 2-6 on the pull rod outer toothed rod 2-3, a lock spring a2-7 is arranged on the nylon slide block 2-5, a slide rail groove 2-9 is arranged on the pull rod inner slide rod 2-1, and pull rod plugs 2-4 are arranged on the slide rail grooves 2-9. The handle 7 is provided with the soft rubber sleeve 3, the two ends of the handle 7 are provided with the lighting devices 5, and the lighting devices 5 are provided with the switches 4.
Specifically, the extension length of the screwdriver bit can be adjusted by adjusting the position of a pull rod plug 2-4 at an outer toothed rod 2-3 of the pull rod under the action of a lock hook plate 2-6 and a locking spring 2-7, a slide rod 2-1 in the pull rod is connected with the pull rod plug 2-4 through the lock hook plate 2-6, the pull rod plug 2-4 can prevent the slide rod 2-1 in the pull rod from being separated from a straight lifting pull rod 2, and the pull rod plug 2-4 is more convenient to transversely displace under the action of a nylon slide block 2-5 and the locking spring 2-8. When the pull rod plug 2-4 is pushed to a corresponding gear by a hand, the slide rod 2-1 in the pull rod pushes the linear screwdriver 1 and the cross screwdriver 6 to move for a corresponding distance, and therefore the extension and contraction of the screwdriver head are achieved.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
