Description

Narrow space screw assembly and disassembly fixer

technical field

The utility model relates to the field of electric equipment, in particular to a screw assembly and disassembly fixer in a narrow space.

Background technique

As a common tool for fastening objects, screws are in great demand on many devices in substations. When carrying out equipment maintenance, eliminating defects, comprehensive self-renovation and technical overhaul, it is often accompanied by the installation and removal of a large number of screws. These screws are often installed in small spaces such as protective screens, switch cabinets, mechanism boxes, and operation boxes. When installing and removing screws in these devices, the work is often difficult due to the narrow space, and the operators cannot conveniently install them. to work. When working, the operator often holds the screw in one hand, and rotates the screw with a screwdriver in the other hand, which is time-consuming, laborious and difficult to operate, and the screw is easy to fall off, and if these screws fall on the running wire or terminal, it will form a short circuit , leading to a series of risks. At the same time, the operator will accidentally touch the live equipment due to the obstruction of the line of sight, which will increase the danger of work.

Utility model content

The utility model is mainly to overcome and solve the above-mentioned risks and problems. The utility model provides a tool for fixing screws when installing and disassembling screws in a narrow space in electric power work. It can install screws in a narrow space conveniently and without risk. It fundamentally solves the problem of difficult installation and removal of screws in narrow spaces.

The technical solution adopted to solve the problems of the utility model is:

A screw mounting and dismounting fixture in a narrow space, comprising two force-applying arms whose ends are connected, and the inner surfaces of the two force-applying arms form a gap for clamping screws; the connection point of the two force-applying arms There is a suspension hole on the top; the force applying arm is an isosceles trapezoidal structure with the width of the end gradually decreasing; the force applying arm is provided with a circular force point; the end of the force applying arm is connected to the Clamping piece; the middle part of each clamping piece is provided with a semi-cylindrical groove, so that when the two semi-cylindrical grooves are combined under force, they form a cylindrical through hole for clamping the screw; the clamping The force arm between the sheet and the stress point is covered with an insulating sleeve.

The positive effects of the utility model are: the utility model is small in size, easy to carry, simple in structure, flexible in use, convenient and durable, and can be widely used in the installation and removal of screws in various work sites in substations in narrow spaces. It reduces the difficulty of work, saves working time, reduces work risks, and significantly improves the work efficiency of operators.

Fig. 2 is the side structure schematic diagram of the utility model;

In the figure: 1-hanging hole, 2-force arm, 3-insulating sleeve, 4-clamping piece, 5-stress point.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, the utility model is a screw mounting and dismounting fixer in a narrow space. The fixer includes a force arm 2 connected at two ends, and the force arm 2 is made of hard materials such as metal or plastic. , the inner sides of the two force-applying arms 2 form a gap for clamping screws; the connection points of the two force-applying arms 2 are provided with hanging holes 1, which are convenient for hanging and placing when not in use; the force-applying arms 2 are Isosceles trapezoidal structure with gradually reduced width at the end; the force applying arm 2 is provided with a circular force point 5, which is convenient for the user to apply force; the end of the force applying arm 2 is connected to an oblique clamping piece 4; the middle part of each clamping piece 4 is provided with a semi-cylindrical groove, so that the two semi-cylindrical grooves form a cylindrical through hole when they are combined under force, and are used to clamp the screw; the clamping piece 4 and the force arm between the force point 5 is covered with an insulating sleeve 3, which prevents the utility model from being connected with a wire or a terminal to form a short circuit when in use.

The utility model can adopt the following steps in the specific operation: when installing the screw, the operator first clamps the clamping part of the device with one hand to the screw, then slowly sends the screw to the screw hole, and then uses Use the other hand to turn the screw with a screwdriver. After the screw and the screw hole are fixed, gently release the clamp to remove the device, and then tighten the screw. When removing the screw, first use the screwdriver to loosen the screw to a certain extent. Then extend the device to the exposed part of the screw and clamp the screw with the clamping piece, and then use the screwdriver to rotate the screw until it is separated from the screw hole. Use the device to clamp the screw to complete the removal of the screw conveniently.

Claims (1)

1. The utility model provides a fixer is installed and removed to narrow and small space screw which characterized in that: the clamping device comprises two force applying arms with connected ends, wherein a gap for clamping a screw is formed on the inner side surfaces of the two force applying arms; a hanging hole is formed in the connecting point of the two force applying arms; the force application arm is in an isosceles trapezoid structure with the tail end width gradually reduced; a circular stress point is arranged on the force application arm; the tail end of the force application arm is connected with an oblique clamping piece; the middle part of each clamping piece is provided with a semi-cylindrical groove, so that a cylindrical through hole is formed when the two semi-cylindrical grooves are stressed and combined for clamping a screw; an insulating sleeve is sleeved on the force application arm between the clamping piece and the stress point.
