Description

TECHNICAL FIELD

[0001] The utility model belongs to screwdriver technical field especially relates to a tool for assisting dismouting screw in narrow space. BACKGROUND

[0002] In some narrow space, for example, power distribution cabinet, there are more electrical components, layout is very compact, when installing components, the channel is very narrow, the operator is difficult to access installation cavity (screw hole), leading to the screw cannot be accurately put into the screw hole, it is inconvenient to screw in, the work efficiency is low, the power distribution cabinet internal part electrical component is live, the operator's operating posture is uncomfortable, there are electric shock risk problems. SUMMARY

[0003] In view of the above problems in prior art, the utility model provides a tool for assisting dismouting screw in narrow space, its technical scheme is: including the shell, at least two grippers are arranged on the outer wall of the shell, at least two spring clips are arranged on the inner wall of the shell, and the screwdriver bit is clamped between the spring clips.

[0004] As a preferred scheme, the inner wall of the spring clip is provided with a non-slip pad to prevent the screwdriver bit from sliding due to gravity.

[0005] As a preferred scheme, the top end of the gripper is provided with a magnetic ring.

[0006] As a preferred scheme, the outer wall of the shell is provided with a flashlight.

[0007] As a preferred scheme, one end of the screwdriver bit is fixedly connected with the screwdriver handle.

[0008] As a preferred scheme, one end of the screwdriver bit is movably connected with the screwdriver handle.

[0009] The utility model has the advantages of:

[0010] (1) the gripper on the shell is used for fixing the screw during dismounting and assembling, preventing the screw from falling off accidentally, and the gripper can also adapt to screws of different sizes, so the utility range is wide;

[0011] (2) the magnetic ring on the gripper can further improve the fixing ability of the screw by magnetic adsorption, preventing the screw from falling off during dismounting and assembling;

[0012] (3) the flashlight on the shell can improve the visibility during dismounting and assembling, thereby improving the efficiency of dismounting and assembling. BRIEF DESCRIPTION OF DRAWINGS

[0017] The present invention will be described in further detail below based on the accompanying drawings and specific embodiments.

[0018] Example

[0019] like Figs. 1-3 The tool shown is for assisting in the removal and installation of screws in a narrow space, comprising a housing 4, at least two grippers 5 provided on the outer wall of the housing 4, and at least two spring clips 3 provided on the inner wall of the housing 4, which clamp a screwdriver bit 1 between the spring clips 3. The grippers 5 are made of a material with good toughness, such as steel or plastic, and the spring clips 3 can ensure that the screw and the screwdriver bit 1 are aligned on the same axis.

[0020] Furthermore, an anti-slip pad 301 is provided on the inner wall of the spring clip 3 to prevent the screwdriver head 1 from sliding due to gravity.

[0021] Furthermore, a magnetic ring 6 is provided at the top of the gripper 5 .

[0022] Furthermore, a flashlight 7 is provided on the outer wall of the housing 4 .

[0023] Furthermore, one end of the screwdriver head 1 is fixedly connected to the screwdriver handle 2, and the tool is used as a common fixed screwdriver.

[0024] Furthermore, one end of the screwdriver head 1 is movably connected to the screwdriver handle 2, and the tool is used as a combined screwdriver.

[0025] The above tool is used as follows: when installing a screw, the screwdriver bit 1 is inserted through the spring clip 3, and the operator places the screw between the gripper 5 and the screwdriver bit 1. The screw is fixed in the gripper 5 by the adsorption force of the magnetic ring 6 on the gripper and the toughness of the gripper itself. Then the screwdriver handle 2 is pushed forward to insert the screw into the screw hole, and then the screw is tightened. At this time, the gripper 5 will be stretched open and the screw can be separated from the gripper 5.

[0026] When removing a screw, when the screwdriver loosens the screw slightly, the screw is grasped by the magnetic ring 6 on the gripper 5 and the toughness of the gripper 5 itself, and then the screw is continued to be loosened until the screw is screwed out;

[0027] When using in a dark place, just turn on the flashlight 7 to illuminate.

[0028] The above tools can be applied to various types of screwdrivers such as a straight, cross, hexagonal, etc. and can also be applied to fixed screwdrivers and combined screwdrivers.
