[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figures 1 to 6 In an embodiment of the utility model, a combined plug gauge includes a handle portion 1 and a plug gauge head assembly 2. The handle portion 1 includes a handle rod 101 and a fan-shaped slot 102. The fan-shaped slot 102 is opened at one end of the handle rod 101 and penetrates to the other end of the handle rod 101.

[0032] The plug gauge head assembly 2 includes a plug gauge head 201, a fan-shaped insert block 202, and a fan-shaped slot 203. Two fan-shaped insert blocks 202 are provided, and the two fan-shaped insert blocks 202 are symmetrically fixed to one end of the plug gauge head 201. The fan-shaped slot 203 is provided on the inner side of the end of the fan-shaped insert block 202 away from the plug gauge head 201. The plug gauge head 201 is plugged into the inner side of the handle rod 101 through the fan-shaped insert block 202 to realize the combination into a plug gauge as a whole.

[0033] The four fan-shaped insert blocks 202 on the two plug gauge heads 201 are close to each other and are cylindrical, and the two plug gauge heads 201 of the same group are staggered and clamped by the fan-shaped insert blocks 202 to achieve storage;

[0034] A quick-release assembly 3 is disposed inside the handle bar 101, and the quick-release assembly 3 includes a locking unit and an unlocking unit;

[0035] The locking unit is used to realize the clamping and fixing of the fan-shaped insert block 202, thereby realizing the installation and fixing of the plug gauge head 201;

[0036] The unlocking unit is used to release the locking unit from the fan-shaped insert block 202, so as to realize the disassembly of the plug gauge head 201;

[0037] The quick-install assembly 3 includes a connecting rod 301 and a fan-shaped block 302;

[0038] The connecting rod 301 is rotatably mounted on the inner side of the handle rod 101. The handle rod 101 has a circular cavity 106 for mounting and rotating the connecting rod 301. The handle rod 101 has rotation grooves 105 at both ends of the circular cavity 106. The rotation grooves 105 are connected to the fan-shaped slots 102.

[0039] The fan-shaped clamping blocks 302 are symmetrically fixed at both ends of the connecting rod 301 and are distributed inside the rotating groove 105. When the fan-shaped inserting block 202 is inserted into the inside of the fan-shaped slot 102, the fan-shaped clamping block 302 is rotated and clamped into the fan-shaped clamping groove 203 to achieve the clamping and fixing of the fan-shaped inserting block 202.

[0040] The unlocking unit includes an annular tooth groove 303, a pressing plate 304, a rack 305, and a W-shaped spring piece 306;

[0041] The annular tooth groove 303 is formed on the outer side of the middle part of the connecting rod 301, and the racks 305 are symmetrically distributed on both sides of the connecting rod 301 and mesh with the annular tooth groove 303;

[0042] The two racks 305 extend to the upper and lower ends of the handle bar 101 and are fixedly connected to the pressing plate 304. The racks 305 are moved by pressing the pressing plate 304 to realize the rotation operation of the connecting rod 301.

[0043] The W-shaped spring piece 306 is fixed to one end of the rack 305 away from the pressing plate 304 , and is used to provide a restoring thrust for the moved rack 305 .

[0044] In this embodiment: it should be supplemented that: a handle portion 1 is equipped with multiple sets of plug gauge head assemblies 2 of different specifications, each set of plug gauge head assemblies 2 includes two plug gauge heads 201, and the two plug gauge heads 201 are a go gauge and a stop gauge;

[0045] In the daily storage state, the two plug gauge heads 201 of each set of plug gauge head assemblies 2 are symmetrically distributed, and the fan-shaped plug blocks 202 of the two plug gauge heads 201 are mutually staggered and plugged, and the combination is a cylindrical shape, which can not only reduce the storage port space, but also realize the independent storage of each set of plug gauge head assemblies 2, which is convenient for management and finding;

[0046] When the plug gauge head assembly 2 and the handle portion 1 need to be used in combination, the operation steps are as follows:

[0047] Take a set of plug gauge head assemblies 2 of the required specifications, then separate the two plug gauge heads 201, then take the handle 1, and press the pressing plate 304 (it should be noted that: one pressing plate 304 can be pressed, or two pressing plates 304 can be pressed at the same time), the pressing plate 304 pushes the rack 305, the rack 305 pushes the connecting rod 301 to rotate through the annular tooth groove 305, and the connecting rod 301 drives the fan-shaped block 302 to rotate 90 degrees, so that the fan-shaped block 302 is completely rotated out of the upper slot 102 and stored in the rotating groove 105, so that the fan-shaped block 302 does not affect the insertion of the fan-shaped plug block 202;

[0048] Then, two plug gauge heads 201 are respectively inserted into the fan-shaped slot 102 from both ends of the handle rod 101 through the fan-shaped insert block 202. When the plug gauge head 201 fits the end surface of the handle rod 101, the fan-shaped slot 203 on the fan-shaped insert block 202 is aligned with the fan-shaped insert block 302.

[0049] At this time, the pressing plate 304 is released, and the pressing plate 304 and the rack 305 are reset under the elastic force of the new spring piece 306, and the connecting rod 301 drives the fan-shaped blocks 302 at both ends to rotate synchronously, and the fan-shaped blocks 302 rotate 90 degrees and snap into the upper slot 203, so that the two plug gauge heads 201 are synchronously installed and fixed, and then the measurement operation can be carried out;

[0050] If it is necessary to replace the plug gauge head 201 of other specifications, it is only necessary to press the pressing plate 304 again to release the fixation of the plug gauge head 201, then take out the plug gauge head 201 and install the plug gauge head 201 of the new specifications. The overall operation is simple and convenient.

[0051] Through the cooperation of the above multiple parts, the plug gauge head assembly 2 can be conveniently disassembled and assembled. Through the detachable structure of the plug gauge head assembly 2, when a single plug gauge head 201 is damaged, only the single plug gauge head 201 needs to be replaced, and the overall operation is more flexible and convenient.

[0052] Please refer to Figures 1 to 4 A middle protrusion 103 is fixedly connected to the middle of the outer side of the handle bar 101, and a contraction groove 104 is provided at the upper and lower ends of the middle protrusion 103. Two pressing plates 304 are symmetrically distributed inside the contraction groove 104. A middle movable groove 107 for the rack 305 to move up and down is provided in the middle of the inner part of the handle bar 101;

[0053] When the pressing plate 304 is in the initial state, one end surface of the pressing plate 304 away from the rack 305 is flush with the outer wall end surface of the middle protrusion 103;

[0054] The sector-shaped block 302 protrudes from the inner side of the sector-shaped slot 102 when in a vertical state.

[0055] In this embodiment, the structure of the middle protrusion 103 is arranged so that the pressing plate 304 will not be squeezed during the daily measurement process, thereby ensuring the installation stability of the plug gauge head assembly 2.

[0056] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
