Description of the Invention: [Technical Field] The present invention provides a wire fixing device, in particular, a clip type wire fixing device. 5 [Prior Art] On the circuit board, extra wires, such as some power cables or squall lines, are sometimes added. In order to prevent these wires from moving freely on the board and affect other components, it must be done in some way. fixed. ~ For example, the signal line for connecting a microphone has been glued to & This method is not only unsightly, but when the tape loses its viscosity, the wire will fall off. Conversely, if the tape is too sticky, the residual glue marks on the circuit board when any wire is replaced or removed, and dust and debris are everywhere. 'It is very inconvenient during use. In the Chinese Patent Application No. 90224302 owned by the applicant, a "wire fixing device" is specifically disclosed, as shown in Figures i and 2, the wire fixing device 3 includes a soldering to the circuit board. The mounting section 31, an elastic arm section 32 extending from one end of the mounting section 31, and an adsorption section 33 extending from the other end of the elastic arm section 32. And by the above three, a space 35 for defining an opening 30 and for arranging the wire is defined. Further, by the example 2, for example, the adsorption section 33 protrudes away from the one side of the elastic arm section 32 toward the line space 35 by a stopper portion 34. Thereby, the circuit engineer can reserve a plurality of pads along the path for preparing the fixed wire during the wiring process for the wire fixing device 3 to be welded, and then, as long as the wires # are respectively inserted into the respective wire fixing devices 3 In the line space 35, it is possible to securely ensure that the wire is in an ideal position and that 8 5 1306375 is not offset. However, the slightest drawback is that since the opening of the wire fixing device is open, in the subsequent process, the possibility of inadvertently pulling to the adsorption section 33 causes the deformation of the elastic arm section 32; secondly, the mounting sections 31 and 5 The distance between the adsorption sections 33 determines the diameter of the wire that can be correctly clamped, so that various sizes of the wire fixing device 3 must be prepared during the preparation; the opening 3〇 is opened in the direction of the substantially parallel circuit board. Once the adjacent circuit components have a certain height In particular, the diameter of some wire rods has been reduced to about 1 mm or less, which will undoubtedly test the eyesight and care of the wire-lined personnel. It is not only difficult to start, but also the probability of damage to the wire fixing device. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a wire fixing device in which an opening is substantially closed to avoid inadvertently pulling. Another object of the present invention is to provide a wire fixing device that can clamp a wire in response to a wire size difference 15 . A further object of the present invention is to provide a wire fixing device in which the direction of the opening is substantially perpendicular to the direction of the board so that the operator can easily mount the wire. Therefore, the wire fixing device of the present invention comprises a mounting portion for soldering on the circuit board, a resilient arm portion extending from one end edge of the mounting portion, and a resilient arm portion away from an end edge of the mounting portion. An adsorption section extending substantially parallel to the direction of the mounting section; and an extension of the other end edge of the mounting section at an angle away from the mounting section. A space is set up by the above-mentioned four. The extension section has a blocking portion away from the edge of the anchorage; thereby, when the wire enters the space of the line 8 1306375, it is restricted by the adsorption section and the blocking part, and is limited to the positioning Within the line space. According to the above configuration, the opening of the wire fixing device is substantially shielded from being easily pulled, the position of the opening is perpendicular to the circuit board, the wire is easily inserted, and the adsorption section is more elastically deformed or rebounded in accordance with the thickness of the wire. There are different responses, which increase the flexibility of use. [Embodiment] The technical content, features and effects of the present invention will be clearly illustrated by the following description of the preferred embodiment and its axis description. Referring to Figures 3 and 4, the present invention will be described. The wire fixing device 1 of the first preferred embodiment is formed by bending a sheet-like member having a material elasticity, and is welded to the -t road substrate by means of surface adhesion to fix the wire 4 on the circuit board. The wire fixing device 1 of the present example comprises: a mounting section 11 for soldering to the circuit board, an elastic K12 extending upward from an end edge of the mounting section u, and an additional end edge of the elastic arm section 12, substantially parallel to the mounting section The adsorption section (1) extending in the 11 direction and the other end edge of the mounting section U are also extended upwards & The above four phase & define - the wire space in this example, the extension 14 has an extension body U2 extending from the mounting section u and extends from the other end of the extension body 142 toward the elastic arm segment η - The abutting portion 141; thereby, when the diameter of the I wire 4 is substantially equal to the space 215, the wire is pushed into the line, and the adsorption section is pushed down to deform the adsorption section 13 and is in the adsorption section. Under the elastic restoring force, the wire 4 is co-interposed with the abutting portion 141 so as to be confined in the line space 15 by 8 1306375. The end of the elastic arm segment 12 coupled to the adsorption segment 13 is defined. The edge direction is a length direction 'the adsorption section 13 is away from the elastic arm section 12 in the width direction. The adsorption section 13 has a length of 5 or a width of 5 to provide a flat adsorption surface for surface mounting. The suction of the nozzle of the technical automation operation causes the wire fixing device to be moved to a position to be mounted on the circuit board. _ In the first preferred embodiment, the length of the abutting portion 141 and the length of the adsorption section 13 are smaller than The length of the elastic arm segment 12, that is, the abutting portion 141 and 1〇 have a gap in the longitudinal direction of the adsorption section 13, and the wire 4 can be pressed against the adsorption section 13, and the deformation of the adsorption section 13 causes the wire 4 to be inserted into the line space 15. A person skilled in the art can easily understand that the adsorption section 13 is disposed below the blocking portion 141, and the blocking portion (4) partially overlaps the longitudinal direction of the adsorption section 13, and does not interfere with the present invention. In addition, the number of the abutting portions is not limited by the H embodiment, and may be as shown in the second preferred embodiment of the present invention, from the extension body to the U end of the mounting portion. The elastic f segment 12 extends to form a plurality of blocking portions 141, 141, and the wire is clamped together with the adsorption portion 13 to achieve the strength of clamping. 20 Referring to FIG. 6, a third preferred embodiment of the present invention, The wire fixing device 2 comprises a mounting portion 21 for soldering on the circuit board, a resilient arm portion 22 extending upward from the end edge of the mounting portion, and a resilient arm portion separating from the mounting portion 21 - End edge, extending in a direction substantially parallel to the mounting section 21! 3〇6375
