Abstract
The utility model relates to a hand screw screwed directly by hands and used for fixing articles such as circuit boards and the like. The utility model is characterized in that a nut (1) is arranged at one end of the screw rod (2), threads (3) are arranged at the other end of the screw rod (2) and a groove (4) is arranged on the nut (1). The utility model has the advantages that the diameter of the handhold nut part is larger than the diameter of the nut of the common screw, the length is longer, and the hand feeling is good and the screwing is facilitated during hand screwing because fine threads are manufactured; the screw rod can be designed with proper length according to the practical need; the production and the manufacturing are facilitated and the hand screw is suitable for common places because the threads are standard threads; and the dissembling and the assembling of the circuit board can be carried out without requiring any tool, and the field maintenance and the field repair are convenient.
Description
Technical field
The utility model be a kind of be used for fixing object such as similar circuit plate directly with the tight hand-screw of hand-screw.Belong to technical field of tools.
Background technique
In existing electronic product, be used for the fixing general employing standard fastening screw trip bolt of circuit board, must tool using when the disassemble or assemble circuit board.This is not too convenient during maintenance, repair at the scene.
Summary of the invention
The purpose of this utility model provides a kind of directly with the tight hand-screw of hand-screw, in order to the fastening screw trip bolt of fixed class like objects such as circuit boards.
Technical solution of the present utility model: its structure is that an end of screw rod is a nut, and the other end of screw rod is a screw thread, has groove on the nut.
Advantage of the present utility model: the nut diameter of holding the general screw of nut part is bigger, length is longer, and is manufactured with microgroove, has excellent handle and screws when being convenient to manual screwing.Spiro rod length can be designed to suitable length according to actual needs; Screw thread is convenient to manufacture and is applicable to and pass through occasion for to use standard thread.Adopt this hand-screw, can just can carry out the disassemble or assemble of circuit board, make things convenient for field maintenance, maintenance not by instrument.
Description of drawings
Accompanying drawing 1 is a main TV structure schematic representation of the present utility model;
Accompanying drawing 2 is attached TV structure schematic representation of the present utility model;
Accompanying drawing 3 is the structural representations of looking up of the present utility model;
Among the figure 1 is nut, the 2nd, screw rod, the 3rd, screw thread, the 4th, groove.
Embodiment
