The upper plate 23 is also substantially in the shape of a square, and includes an upper surface 231 and a fourth abutting surface 233 opposite to the upper surface 231. The upper surface 231 of the upper baffle 23 is adjacent to the two ends thereof. The fifth screw hole 224 of the side baffle 22 corresponds to the third sixth screw hole 235. The sixth screw hole 235 has the same shape as the third screw hole 214 on the second abutting surface 211 of the bottom plate 21. The fourth abutting surface of the upper baffle 23 is provided with four sixth abutting grooves 237 (see FIG. 2) corresponding to the four third abutting grooves 135 of the cover body 13 and having the same structure. The 〇 includes a support portion 31 and a substantially straight cube-shaped support portion; and a bend of the both ends of the support Deng 31 bent toward one surface thereof = 32. The support portion 31 includes two opposite side surfaces. And the two side tables=two straight dome surfaces 34. The support portions 31 are spaced apart from each other to provide two large openings 331 extending through the two side surfaces 33. The connecting portion 331 cooperates with the bending portion for connecting the Μ and the external power mechanism (not shown) such as a cylinder, etc. The top surface of the support # 31 is also π female &< 21 J- ^ ^ - 1 3, there is a second screw hole M2 corresponding to the bottom plate of the resisting mechanism 20, the third screw hole M2. The inner diameter of the inner diameter G is a magazine, and the outer diameter thereof and the first abutting groove 20 The bottom plate 21 is fixed to the base 30 by the first side of the bottom platen screw 50 from the third screw hole 214 to the seventh screw hole 342 of the base 11 of the 200923371. Then, the two side plates 221 are placed on the two ends of the bottom plate 21, so that the second abutting surfaces 223 of the two side baffles 221 face each other, and the fifth screw holes 225 and the bottom plate 21 on the two side baffles 221 are The fourth screw holes 215 of the end are respectively aligned, and then screwed from the fourth screw hole 215 to the fifth screw hole 225 on the fourth connecting surface 222 of the side baffle 221 by the second screw 50 to make the two side blocks The plate 221 is fixed to the bottom plate 21. An elastic member 4 夹 is placed in each of the fourth abutting groove 212 and the second abutting groove 226 of the bottom plate 21 and the two side baffles 221 , and the holding unit 10 is placed between the two side baffles 221 . The other end of each elastic member 4 is inserted into the corresponding bottom abutting groove 118 and the second abutting groove ii 9 of the bottom surface 114 and the second second surface ι of the holding unit 10. The __elastic member 4 夹 is placed in each of the third abutting grooves 135 of the cover 13 of the holding unit 10, and the upper plate 23 is pressed thereon, and each elastic member 4 is spliced to the other end. Inserting into the corresponding sixth resisting groove 237 of the upper baffle 23, and finally screwing the sixth screw hole from the two ends of the upper striking plate 23 into the two side supporting plates 221 ^ the third connecting surface 221 by screws The fifth screw hole 224 is used to fix the upper board and the two side shutters 221 . Referring to FIG. 4 and FIG. 5, when the holding device is used, the columnar head 61 of a data cable plug 60 is inserted into the receiving slot 115 of the holding body n from the side of the base 〇 弯 邙 π. The conductive terminal 6! 2 extending from the inner column 61 is from the other end of the accommodating groove 115 to the other end. One side of the bent portion 32 of the stern 30 is connected to an external power device such as a steam rainbow (not connected, the base is driven by the external power device, the μ device _ and the data cable plug 60 are fixed; U疋's object to be tested, such as mobile phone movement. 200923371 Due to the resistance mechanism 20, the two gamma Ba #1 丨 baffle 22 is slightly larger than the two sides of the holding body 11 113 + day of the day - the resisting surface 131 and the first The distance between a connecting surface 132 and the distance between the top surface 112 of the holding body u and the bottom surface ι 4 is equal to that in the resisting mechanism 2, and is fixed by the elastic member 40, by means of elasticity The piece 4" is in a floating state, which can be offset by the resistance machine. The object to be tested is fixed by the fixture, and the holder is held: the object to be measured is not positioned due to the dimensional tolerance between the objects. On time: 10, by making a slight offset in the resisting mechanism 20, the data sub-612 is automatically aligned with the data line socket on the object to be tested (the reason is to insert the conductive terminal 612 of the data line.) The tolerance between the fixture and the object to be tested is caused by: , the problem. The holding device 100 and the steam red, etc. In combination, it can reach the insertion and extraction strength and the entry and exit angle # ''·〇Test system stability. The purpose of the heart is 'to improve the test: understand the 'the holding unit 10 and the resisting machine: the second surface resists The elastic member 4〇 may be one or the same, and the corresponding abutting groove may be a pair or a pair or more. It can be understood that the base 30 can be configured in a clear manner. The body structure can be understood that the cover body 13 and the holding body u can also be understood as a body, and the holding unit can be divided into four bodies. The holding body 11 can be rooted 13 200923371 according to the held data line plug. The bottom plate 21, the two side baffles 22, and the upper baffle 23 of the resisting mechanism 20 may be integrally fixed to each other as long as the size and shape are different. The cavity of the holding body 10 can be accommodated.
