Description

Screwdriver with stabilizer bar

Technical Field

The utility model relates to a screwdriver with stabilizer bar.

Background

The screwdriver is a common tool in work in life, the screwdriver in the prior art is of a straight rod structure, and the screwdriver is detached through rotation of the screwdriver.

However, in practice, it has been found that the stability of a screwdriver is poor when operated with one hand, while the size of the screwdriver is limited, and that the stability can be improved when operated with two hands, but the portion of the screwdriver that can be gripped is limited.

Based on the above problems, we have designed a screwdriver with a stabilizer bar that improves operational stability.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a promote operating stability's screwdriver that has a stabilizer bar.

In order to solve the above problem, the utility model adopts the following technical scheme:

a screwdriver with a stabilizer bar comprises a screwdriver rod, wherein a screwdriver head is arranged at the left end of the screwdriver rod, a plurality of positioning strips are annularly arranged at the position, close to the left side, of the outer wall of the screwdriver rod, a sliding pipe is assembled outside the screwdriver rod, positioning grooves corresponding to the positioning strips are annularly arranged on the inner wall of the sliding pipe, and when the positioning strips are matched with the positioning grooves, the screwdriver rod and the sliding pipe rotate simultaneously; a handle is screwed in the outer wall of the sliding pipe.

Preferably, a polygonal end head is arranged at the right end of the cutter bar, a connecting seat is assembled at the right end of the cutter bar, a through hole for penetrating the cutter bar is formed in the axis of the connecting seat, a polygonal positioning hole is formed in the right end of the through hole, and the end head is matched with the positioning hole; a first handle is inserted into the right end of the connecting seat, and a stud bolt is matched between the first handle and the connecting seat; in the structure, the cutter bar can be pulled out to the right side after the first handle is detached, so that the whole disassembly of the device is realized, and the device is easy to maintain.

Preferably, an annular groove is arranged outside the first handle, and a handle sleeve made of rubber is assembled through the annular groove; the handle sleeve is arranged to reduce slippage between the palm and the first handle.

Preferably, the diameter of the handle sleeve is gradually increased toward the right side.

Preferably, the right end of the handle sleeve is provided with a convex part, and the inside of the convex part is hollow; when the cutter rod is pressed downwards, the palm needs to abut against the first handle, and the palm is directly painful to contact with the first handle, so that the protruding part is designed, the palm is contacted through the protruding part, and pain is reduced.

Two modes of operation of the device are as follows:

for conventional screw disassembly: sliding the sliding pipe to separate the sliding pipe from the positioning strip, wherein the sliding pipe can rotate along the cutter bar; the screwdriver head is aligned with the screw, the handle is held by the left hand to assist in fixing the cutter bar, and the cutter bar is rotated by the right hand to realize the disassembly of the screw.

Disassembling an over-tightened screw: the sliding tube is slid to keep the matching of the sliding tube and the positioning strip, at the moment, the left hand is used for righting the cutter bar, and the left hand is used for applying rotating torque to the handle to realize the disassembly of the screw.

The utility model has the advantages that:

1) in the device, the cutter bar can be positioned in a rotating way through the sliding pipe, so that the stability of the cutter bar in the rotating process is improved;

2) meanwhile, the sliding tube can be matched with the cutter bar, and the rotating torque is applied through the handle after the sliding tube is matched with the cutter bar;

3) the structure of this device is comparatively simple, and the cost is comparatively cheap, is fit for using widely.
