Embodiment Construction

[0022] refer to Figure 1-Figure 3 , the double-headed high-torque screwdriver of this preferred embodiment includes a handle 1 and a handle 2; wherein, there is a first concave channel 101 arranged in the axial direction of the handle in the handle, and the first concave channel is divided into a middle section 102 and a middle section 102. The two end sections 103, the middle section and the two end sections all have substantially the same circular cross-section, and the diameters of the two end sections are larger than the middle section diameter. At this time, a stepped hole is formed at the transition between the two end sections and the middle section, and the stepped hole It acts as the limit hole 104 of the cutter bar. Both ends of the handle also have a second recessed channel 105 arranged perpendicular to the axial direction of the handle, and the moment rod 3 can be arranged in the second recessed channel. The cutter bar 2 is accommodated in the first concave chann...

Abstract

The invention discloses a double-head large-torque screwdriver. The double-head large-torque screwdriver comprises a screwdriver handle (1) and a screwdriver rod (2), a first concaved channel (101) is formed in the axial direction of the screwdriver handle (1), and the screwdriver rod (2) is contained inside the first concaved channel; the screwdriver rod (2) slides inside the screwdriver handle to be adjusted to a working position screwdriver head end or keeps a relative fixed position with the screwdriver handle under limiting of a limiting component to limit a working position screwdriver head station; second concaved channels (105) which are perpendicular to the axial direction of the screwdriver handle are further formed in the two ends of the screwdriver handle (1), and a torque rod (3) can be arranged inside each second concaved channel. The problem that an existing screwdriver is inconvenient to replace is solved; meanwhile, large-torque operation is achieved.

Description

technical field [0001] The present invention relates to screwdriver tools. Background technique [0002] In actual work, there will be corresponding screw disassembly and fastening work in the process of product production, assembly, and maintenance. The screw heads are generally different from cross and straight. Generally, two screwdrivers with corresponding head shapes are used for work. However, in the field construction process, it is easy to cause the omission of the screwdriver. In view of the above problems, the prior art provides a screwdriver with a detachable bit, which realizes the work of disassembling and fastening screw heads of different shapes with one screwdriver. At the same time, there is still a problem. There may be oil stains and pollutants with strong adhesion in the bad environment on site. Using the screwdrivers currently on the market to replace the screwdriver head will cause the hands of the staff to be stained with dirt. [0003] In addition, ...
