Four straight slots 105 are arranged along the annular ring. Two limiting blocks 106 are provided. The two limiting blocks 106 are fixed to the inner side of the two symmetrically distributed straight slots 105 and protrude to the outer side of the annular block 104. The handle rod 101 is equipped with a combined ring gauge assembly 2 via an annular block 104 and a limiting block 106. The combined ring gauge assembly 2 is used to perform various external thread inspection operations. The combined ring gauge assembly 2 includes a semi-circular ring gauge 201, a straight groove slot 202, and a connecting half-sleeve 203; The straight groove 202 is opened on the outside of the semi-circular ring gauge 201. The semi-circular ring gauges 201 are symmetrically arranged in pairs and sleeved on the outside of the straight groove opening 105. The semi-circular ring gauges 201 are connected to the outside of the limiting block 106 through the straight groove 202. The connecting half sleeve 203 is fixed to the rear end of the semi-circular ring gauge 201 and sleeved on the outside of the handle rod 101. Multiple semicircular ring gauges 201 are arranged sequentially from the inside to the outside. The length of the multiple semicircular ring gauges 201 increases sequentially from the inside to the outside, and the inner side of the multiple semicircular ring gauges 201 is sequentially formed with internal threads of different specifications to realize the detection of external threads of different specifications.

[0015] In this embodiment: by setting up a structure of multiple semicircular ring gauges 201 with increasing length from the inside to the outside, and with different specifications of internal threads formed on the inner side of the multiple semicircular ring gauges 201, the detection operation of external threads of different specifications can be realized. For example, the outermost and longest semicircular ring gauge 201 can be used to detect the largest specification of internal thread, and the outermost and most end semicircular ring gauge 201 can be used to detect the smallest specification of internal thread. During this process, the connection between the semi-circular ring gauge 201 and the external thread being tested can be checked through the opening of the straight groove 202, so as to determine in time whether the external thread being tested is qualified. Through the above structural design, a set of handle assembly 1 and combined ring gauge assembly 2 can realize the detection of internal threads of various specifications, making it more widely used, more flexible and convenient.

[0016] Please refer to this carefully. Figures 1-3 The outer diameter of the annular block 104 is larger than the outer diameter of the handle rod 101. The innermost semicircular ring gauge 201 has an annular groove 206 that matches the outer wall of the annular block 104. The inner diameter of the innermost semicircular ring gauge 201 is smaller than the inner ring diameter of the annular block 104. Multiple connecting half-sleeves 203 corresponding to multiple semi-circular ring gauges 201 of different diameters are sequentially sleeved from the inside to the outside, and the outer side of each connecting half-sleeve 203 is formed with an external thread groove 204. The outer side of the handle rod 101 is fitted with a fastening nut 205 that is threadedly connected to the outermost connecting half-sleeve 203; Two handle rods 101 are symmetrically arranged and distributed. The two handle rods 101 are respectively fixed with studs 102 and have screw holes 103 at their close ends. The assembly and fixation of the two handle rods 101 are achieved by the threaded connection between the studs 102 and the screw holes 103.

[0017] In this embodiment, it should be noted that: semicircular ring rails 201 and connecting half-sleeves 203 of different diameters are equipped with fastening nuts 205 of corresponding specifications. In actual use, the number of semicircular ring rails 201 at the end of the handle rod 101 can be adjusted as needed. The two detachable handle rods 101 are designed to facilitate the replacement of the corresponding fastening nuts 205 according to the specifications of the outermost semicircular ring rail 201. In addition, the semicircular rails 201 at the ends of the two handle rods 101 can be arranged in ascending order from left to right. For example, the innermost semicircular rail 201 at one end of one handle rod 101 has the smallest diameter, and the second semicircular rail 201 has the third largest diameter. On the other end, the innermost semicircular rail 201 has the second smallest diameter, and the second semicircular rail 201 has the fourth largest diameter. In this way, while achieving an increase in specifications, more specifications of testing operations can be performed.
