Embodiment 1

[0032] Such as Figure 1-2 As shown, a multifunctional screwdriver includes a handle 2 and a knife bar 3 connected to the handle 2. The lower end of the knife bar 3 is provided with a straight knife head 3014, and the middle part of the lower end of the knife head 301 is provided with a knife edge 304. The upper end of the knife edge 304 is a concave arc structure, and the upper end of the knife edge 304 is a concave arc structure. In the process of tightening the iron wire with a screwdriver, the knife edge 304 can be better matched with the iron wire, which not only allows the clip The holding is more reliable, and the force-bearing area is increased, which prevents damage to the iron wire during the tightening process and ensures the service life of the iron wire.

[0033] Elastic metal sheet 303 is all provided with on the inner wall of both sides of described knife edge 304, two elastic metal sheet positions are opposite, and described elastic metal sheet 303 is the circu...

Embodiment 2

[0035] Such as Figure 3-6 As shown, a multifunctional screwdriver also includes a hammer 1, the hammer 1 includes a hammer body 104, the two ends of the hammer body 104 are hammer heads 101, and the middle part of the lower end of the hammer body 104 is provided with a connecting sleeve 103 , the inner cavity of the connecting sleeve 103 is a prismatic structure, the middle part of the hammer body 104 is provided with a tool bar hole 102, and the tool bar hole 102 is a through hole, and the tool bar hole 102 communicates with the connecting sleeve 103 , The upper edge of the tool holder hole 102 is provided with a chamfer 105 structure. Such as Figure 7 , when withdrawing the screw, the chamfered part of the knife bar hole 102 can be fixed at the screw head, the knife bar 3 passes through the knife bar hole 102 to unscrew the screw, and the knife bar hole 102 can guide and fix the knife bar 3 It solves the problem that due to the long-term use of the screw, the groove at t...

Embodiment 3

[0039] Such as Figure 8 As shown, the inner wall of the connecting sleeve 103 is provided with internal threads, the upper end of the handle 2 is provided with external threads, and the connecting sleeve 103 is threadedly connected with the handle 2 . The threaded connection can ensure the firmness of the connection between the hammer 1 and the handle 2, avoid slipping during use, and ensure the safety of use.

Abstract

The invention discloses a multifunctional screwdriver which comprises a handle and a toolbar connected with the handle. A linear tool bit is arranged at the lower end of the toolbar. The multifunctional screwdriver is characterized in that a tool edge is arranged in the middle of the lower end of the tool bit, an elastic metal piece is arranged on the inner wall of each of two sides of the tool edge, the two elastic metal pieces are opposite in position, each elastic metal piece is of an externally-convex arc structure, and a cylindrical steel wire hole is formed in the upper end of the tool edge and is a through hole. The tool bit of the screwdriver is provided with the tool edge and the steel wire hole, so that functions of clamp-type tools are replaced, the problem that a steel wire cannot be tightened by using a common screwdriver when a clamp is forgotten to carry is solved, and convenience is brought to mounting and maintaining; due to lever laws, the process of tightening the steel wire is quite labor-saving, so that the problem of labor consumption when sharp-nose pliers are used to mesh and tighten thick steel wires is solved, operating efficiency is improved, working intensity is relieved, and the multifunctional screwdriver is high in usability.

Description

technical field [0001] The invention relates to the technical field of maintenance tools, in particular to a multifunctional screwdriver. Background technique [0002] A screwdriver is a tool used to fasten or remove screws. A flat-blade screwdriver usually has a thin wedge-shaped head that can be inserted into a slot or notch in the screw head. During daily maintenance, especially when it is necessary to use steel wires to tie two hoses tightly, if you use needle-nose pliers to twist thicker steel wires, it is difficult to ensure fastening, and it takes a lot of effort to hold the pliers tightly handle; if there is no pliers such as needle-nose pliers or flat-nose pliers at hand, using an ordinary screwdriver will not be able to tightly twist and wind the steel wire used for the baling hose on the metal round pipe, which will cause inconvenience to installation and maintenance . Contents of the invention [0003] The present invention aims at the above-mentioned deficie...
