Detailed Description

In order to make the utility model realize, the technical means, the creation characteristics, the achievement purpose and the efficacy are easy to understand and understand, the utility model is further explained by combining the specific implementation mode.

As shown in fig. 1 to 4, a multifunctional screwdriver comprises a handle 1, the front end of the handle 1 is provided with a sleeve 2, the front end of the sleeve 2 is communicated with an isolation sleeve 3, a front rod 31 is slidably connected with the isolation sleeve 3, the top end of the front rod 31 is provided with a hexagonal suction groove 311, the hexagonal suction groove 311 is magnetized, the hexagonal suction groove 311 is internally provided with a screwdriver bit 8, the lower end of the front rod 31 is provided with a wafer 4, the wafer 4 is slidably connected with the sleeve 2, the wafer 4 is provided with a rear rod 7, the rear rod 7 is coaxially arranged with the front rod 31, the rear end of the rear rod 7 is slidably connected with the handle 1, the handle 1 is provided with a fastening screw 11, the fastening screw 11 is used for locking the rear rod 7, the sleeve 2 is provided with a spring 5, the spring 5 is arranged between the wafer 4 and the front end of the handle 1, the side wall of the sleeve 2 is provided with a through groove 21, the wafer 4 is provided with a shifting block 41 outside, and the shifting block 41 is slidably connected with the through groove 21. The spring 5 can be sleeved outside the rear rod 7. The isolation sleeve 3 is made of a non-ferrous or non-magnetic material, such as hard rubber or hard plastic.

In this embodiment, a plurality of clamping grooves 6 are further formed in the sleeve 2, and the clamping grooves 6 are all communicated with the through grooves 21. And a rubber stop dog 61 is arranged at the inlet of the clamping groove 6. The clamping groove 6 can pre-fix the positions of the shifting block 41 and the wafer 4, so that the wafer 4 and the shifting block 41 are prevented from being reset by mistake. The rubber stop block 61 can prevent the shifting block 41 from slipping out when being clamped into the clamping groove 6, and the rubber stop block 61 is moderate in hardness and elastic, so that the shifting block 41 can be conveniently clamped.

In this embodiment, a storage groove 9 is provided in the rear portion of the handle 1, and a plug 91 is provided at an opening of the rear end of the storage groove 9. The storage groove 9 can be used for placing the replaceable screwdriver head 8, and the storage groove 9 can also provide necessary space for the telescopic sliding of the rear rod 7.

The working process and principle are as follows:

before stretching into a narrow area, the fastening screw 11 is unscrewed, the shifting block 41 and the wafer 4 are pulled backwards, the wafer 4 compresses the spring 5 and drives the front rod 31 and the rear rod 7 to slide towards the handle 1 together until the front rod 31 and the screwdriver head 8 are both retracted into the isolation sleeve 3, and the phenomenon of mistaken adsorption can be well prevented because the isolation sleeve 3 has no magnetism. Can block 41 cards this moment into draw-in groove 6, when reaching near the screw, dial 41 draw-in groove 6 entering logical groove 21 of dialling, disk 4 slides forward under the effect of spring 5 and resets, and rod 31 and back pole 7 stretch out forward before disk 4 drives, and it can to screw up fastening screw 11 this moment, and it can to rotate the screw removal on inserting the screwdriver bit 8 of front end the screw. After the screw is disassembled, the screw can be directly retracted into the isolation sleeve 3 according to the steps, and the screw is prevented from falling off due to mistaken adsorption in the retraction process.

It will be appreciated by those skilled in the art that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
