In other words, the pre-force applying unit of the seed type can be applied to the search of the present invention. Moreover, due to the foregoing various types of pre-force applying unit structures, it is well known to those of ordinary skill in the art and can be found in For example, the patents of the Republic of China No. 1 and No. 9 are not the technical features of the patents requested by the author. Therefore, the applicant will not repeat them here. The conductive unit 80 includes an insulating member 82' fixed to the bottom of the base 30, and a first conductive member 84 and a second conductive member 86 disposed on the insulating member 82 and the rear cantilever 52. The two conductive members 84,% can be in contact with each other and electrically conductive. The probe 6G is disposed on the hub 5 of the suspension member for contacting the object to be tested 9 by the needle tip portion 64. The positioning of the probe 6 ( ) in the seat , is first inserted into the positioning hole 512 b of the needle holder 5 以 as shown in FIG. 4 , and the positioning hole 51 is The axial direction is perpendicular to the top surface 512a of the body 512 of the needle holder 51, and the yoke angle α of the probe 6 〇 positioning portion 66 and the elongated body portion 62 is an obtuse angle greater than 9 degrees, so 'in the probe After the positioning portion 66 of the 60 is inserted into the positioning hole 512b, the elongated body portion 62 naturally extends obliquely upward relative to the top surface 512& and further, the length of the elongated body portion 62 is designed to be added to the front M438631. The angle of the fastening portion is such that the fastening portion 622 接近 of the elongated body portion 62 adjacent to the needle tip portion 64 is higher than the buckle portion of the needle holder 51 as long as the height of the fastening portion 622 is high. Higher than the height of the card (10)). Then, the user can apply an external force to the elongated body 62 of the probe 6 to elastically bend and deform the elongated body 62 downward, so that the fastening section 622 is firstly defeated. Going to the open space 5]6, and then entering the card slot 514c of the latching portion 514 of the needle holder 51, and then engaging the card engaging surface 514d of the latching portion 514, by the probe 6 The elastic restoring force of the crucible itself, the probe 60 and the hub 51 can be fixed to each other as shown in FIG. When the user wants to remove the probe 6 ,, the probe 6 is released from the probe portion 60 and the elongated body portion 62 is disengaged from the buckle portion 514 ′ to release the probe 6 〇 and the hub. The fixing relationship of 51 is further removed from the needle holder 51. It is found that in the above embodiment, in order to prevent the probe 60 from being plastically deformed due to excessive bending during the dressing and disassembly process, and in order to enable the probe to maintain an appropriate elastic restoring force, the card is stuck. The predetermined angle α is preferably designed to be one degree, but the predetermined angle α is not limited to 100 degrees, for example, it may be 95 degrees '105. Degree and so on. In fact, the predetermined angle α can be set as long as the elongated body portion 62 can be appropriately tilted and extended upwards, however, the ease of installation, the possibility of plastic deformation, and the material properties of the existing probe can be considered. The parameter "the diameter and the length of the elongated body portion" is set to be substantially greater than 9 degrees and 135 degrees. Since the probe 60 can be fixed to the needle holder 51 without a screw, the user can quickly disassemble and mount the probe, and the elastic piece 4 can be prevented from being damaged by the action of the locking screw. Two conductive parts, %. Moreover, as shown in the sixth figure, since the positioning portion 66 of the probe 60 and the needle tip 4 64 are opposite to the elongated body & and are bent downward and extended on the same plane 'When the probe 6G is fixed to When the charm is 51, the probe 60 has only the buckle portion .514 of the needle holder 51, and the buckle portion ... is equivalent to the maximum β distance of the object to be tested 9 ,, J, and thus, the creation The edge finder 20 is equipped with a ” 乂 助 乂 乂 乂 乂 乂 乂 乂 助 助 助 助 助 助 助 助 助 助 助 助 助 助 乂 乂 乂 乂 乂 乂 乂 乂 乂 乂 乂 ” ” ” ” ” ” ” ” ” ” ” It can be close to the object to be tested 9G without being interfered by the needle holder, thereby obtaining a more accurate detection result. The structure design of the probe 6〇 and the needle holder 51 makes the probe stick Connect, ^ Axis - Personal (4), allow the integrating sphere to be as close as possible to the object 90'. Therefore, the positioning portion of the probe 6〇 is down ^ ^ and is close to the miscellaneous body 62 and the needle tip 64 - plane On the top, ^ stomach ^ better design 'Because' set the positioning part is bent upwards and two must be fixed to fix the structure of the positioning part 'this body == Above the needle - (10) space, and cause the opening of the integrating sphere 1 Z (four) secret _ W turn the county for the inspection of the branch. In addition, please refer to the seventh figure, the seventh figure reveals the edge finder provided. The position portion 66 can also be substantially bent and extended perpendicularly to the elongated body portion 62, that is, the predetermined angle α is equal to 90 degrees; at the same time, the positioning hole 512b of the needle holder 51 is opposite to the body The top surface 512a of 512 is inclined upward and extends rearwardly such that the axial direction L1 of the positioning hole 512b and the normal line L2 of the top surface 512a are approximately equal to an angle β of 1 degree. Similarly, it must be stated that In this embodiment, the angle ρ of the 1 degree is a preferred design. Actually, the angle β is not limited to 1 degree, and the angle β is substantially greater than 0 degrees and less than 45 degrees. In this manner, when the positioning portion 66 of the probe 60 is inserted into the positioning hole 512b, the elongated body portion 62 similarly extends obliquely with respect to the top surface 512a, so that the elongated body portion 62 can be subjected to an external force. The card is elastically bent to the card portion 514, and the same can be achieved as in the first preferred embodiment of the present invention. The function of the device is as follows: in the foregoing embodiments t, the elastic piece 4 is substantially connected between the seat body 30 and the suspension member 50 in a horizontal posture, that is, as shown in the fourth figure and the seventh figure. As shown in the figure, the elastic piece 40 is connected between the base body 30 and the suspension member 5〇 in such a manner that its maximum surface 4 is substantially parallel to the direction of the material 5G. However, as shown in the eighth figure and The third embodiment shown in the ninth preferred embodiment is that the elastic piece 4G can also be substantially in a vertical position between the body 3 and the cantilever member 50; in detail, the elastic piece 4 〇 $ ^ and - the rear surface 42, the upper half of the elastic piece 4 is attached to the front side % of the seat body 3 by the surface 42 , and the lower portion of the elastic material 440 is + The rear surfaces 41, 42 are attached and fixed... the rear end of the needle holder 51 and the rear end of the rear cantilever arm. In other words, the elastic piece M438631 40 is connected to the base body 30 and the suspension arm member 50 such that the largest surface thereof (that is, the front surface 41 or the rear surface 42) is substantially perpendicular to the long axis direction of the suspension member 50. between. Therefore, even if the user presses the probe 6 过 too much to cause the suspension member 5 to swing, the elastic piece 4 不易 is not easily plastically deformed because the direction of the urging force is substantially parallel to the elastic piece. The direction in which the 40 is disposed, that is, the aforementioned urging force generally applies a tensile force to the elastic piece 4〇 instead of a bending force, so that the elastic piece is not easily plastically deformed.

In the foregoing third preferred embodiment, the elastic piece 4 has an empty portion 44 (as shown in the eighth figure). The hollow portion 44 is elongated and located above the elastic 1±4G. Between the lower half and corresponding to the gap 24 between the seat and the rear cantilever 52 (as shown in FIG. 9), and the longitudinal direction of the material is substantially perpendicular to the cantilever member 5 The long axis direction of the crucible; thereby, when the conductive members 84, 86 of the edge finder 20 are disconnected, the elastic piece 4 is tied to the left and right sides of the ray "44" to produce elastic bending and eccentricity. It is provided that the elastic restoring force of the miscellaneous y 4 () can be moderately reduced. However, in actuality, the elastic piece 40 may not have the hollow portion 44' provided so that the bent portion of the elastic piece 4b has a preferable rigidity. In the third preferred embodiment, the manner in which the suspension member 50 is disposed is not limited to the embodiment. For example, the needle holder _ _ the rear cantilever 52 may not be connected to the elastic piece 4 ,. And the needle seat = and the (four) arm 52 are fixedly connected or connected to each other to be synchronously oscillated. The tongue can be replaced by the tongue - the elastic piece is a single-member of the groove, and the elastic piece 4 can be inserted into the 15 M438631 in a substantially vertical position. It is worth mentioning that the needle holder 51 is usually an electric conductor to The probe 60 is transmitted to the probe 60 and then transmitted to the object to be tested. When the hub 51 is not integrally connected with the rear cantilever 52, the rear cantilever 52 can be an insulator to make the probe 60 and the conductor 86 There is no indirect electrical connection; however, when the hub 51 and the rear cantilever 52 are integrally formed and are electrically conductive, an insulating member must be disposed between the rear cantilever 52 and the electrical conductor 86. It is to be noted that, in the foregoing embodiments, the positioning hole 512b of the needle holder 51 is a countersink having a tapered head and a communicating with the tapered head. The positioning portion 66 of the probe 60 can be easily inserted into the positioning hole by the design of the countersink, but the shape of the positioning hole 512b is not limited thereto. In addition, the latching portion 514 of the hub 51 does not have a slot 514e, that is, the latching portion 514 is configured to allow the probe 6 to be abutted against the slotted wall of the fox-shaped groove. As long as the long strip 62 of the probe 6G can be abutted and solidified, the main technical feature of the edge finder provided by the present invention is that the positioning hole and the buckle portion are utilized. The needle holder 51 of the 514 is provided with the elastically deformable probe 60 ′ so that the probe 6 〇 can be pressed against the buckle portion 514 by an external force and elastically bent, thereby achieving the function of quickly disassembling the probe 卯. It is conceivable that the hub 51 can be any component of the spotting device for fixedly arranging the probe 6〇, that is, the hub 51 is not used in the edge finder 20. Finally, it must be stated again that 'the composition of the present invention disclosed in the previous examples' is only an example, and _ to limit the scope of the case, M438631 alternatives or changes to other equivalent components, should also apply for this case Covered by the scope of patents. 17 [Simple description of the diagram] The first picture is a three-dimensional combination diagram of the conventional edge finder; the second picture is the side view of the edge finder shown in the first figure; If the picture is combined; read... and ^ four pictures are the partial side view of the first part, which shows that one of the probes of the edge-finding test and the needle-thread are mutually secretive; ° the fifth picture is the first of the creation - difficult The stereoscopic exploded view of the stylus holder and the probe provided by the real off; w ^, in the figure, only the probe material of the edge finder is fixed, and the probe is The seventh aspect of the present invention is a side view of the edge finder provided by the second preferred embodiment, which shows that the probe of the edge finder is not connected to a needle holder; The eighth figure is the exploded view of the edge-trigger provided by the creation-third preferred embodiment in a feeding unit; and the ninth figure is a partial side view of the eighth figure, showing the seeking One of the probes and one of the needle holders are not fixed to each other.
