Referring to fig. 1-3, fig. 1 is a schematic structural view of a feeler with replaceable feeler blades according to an embodiment of the present application, fig. 2 is a schematic partial sectional view of a base and the feeler blades at a-a in fig. 1, and fig. 3 is a schematic partial sectional view of the base, the telescoping mechanism and the feeler blades at a-a in fig. 1. The feeler 10 comprises: the device comprises a base body 11, a telescopic mechanism 12 and a feeler gauge piece 13, wherein the feeler gauge piece 13 is detachably connected with the base body 11.
A first limiting hole 111 and a containing hole 112 are sequentially formed from the surface of the seat body 11 inwards along the axial direction of the seat body 11, and the first limiting hole 111 is communicated with the containing hole 112.
The telescoping mechanism 12 includes an elastic member 121 disposed in the accommodating hole 112 and a ball 122, the ball 122 is in contact with the elastic member 121, and the ball 122 is snapped into the first position-limiting hole 111.
One end of the feeler gauge piece 13 is provided with a second limiting hole 131 corresponding to the first limiting hole 111, and the ball 122 can be inserted into or moved out of the second limiting hole 131 by the elastic force of the elastic member 121, wherein when the feeler gauge piece 13 is installed on the seat body 11, the ball 122 is simultaneously inserted into the first limiting hole 111 and the second limiting hole 131.
The terms "first", "second" and "third" in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any indication of the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.
The elastic member 121 may be a spring, an elastic ring, or other devices with certain elasticity. The elastic member 121 functions to push the balls 122 up and down. The elastic member 121 is exemplified by a spring in this embodiment.

When the second position-limiting hole 131 of the feeler gauge piece 13 is aligned with the first position-limiting hole 111 of the seat body 11, the ball 122 is no longer pushed by the feeler gauge piece 13, and under the action of the restoring force of the elastic piece 121, the elastic piece 121 and the ball 122 move toward the feeler gauge piece 13 until part of the ball 122 is pushed into the second position-limiting hole 131, so that the feeler gauge piece 13 is locked with the seat body 11, and the installation is completed.
The operation process of the ball 122 moving out of the second position-limiting hole 131 by the elastic force of the elastic member 121 is as follows: when the feeler gauge piece 13 is pulled, the outer wall of the feeler gauge piece 13 contacts with the ball 122, the feeler gauge piece 13 continues to move, the outer wall of the feeler gauge piece 13 pushes the ball 122, so that the elastic member 121 is compressed, and the ball 122 and the elastic member 121 move to the bottom of the accommodating hole 112 due to the pushing force of the feeler gauge piece 13 until the ball 122 and the elastic member 121 are compressed into the first limiting hole 111 and the accommodating hole 112, so that the feeler gauge piece 13 is separated from the seat body 11, and the detachment is completed.
In this way, the clearance gauge 10 that this application provided includes pedestal 11, telescopic machanism 12 and clearance gauge piece 13, and the first spacing hole 111 on the pedestal 11 corresponds the setting with the spacing hole 131 of second on the clearance gauge piece 13, and telescopic machanism 12 includes elastic component 121 and ball 122, and ball 122 can receive elastic component 121's elasticity can be gone into or shift out the spacing hole 131 of second, and then realize clearance gauge piece 13's installation and dismantlement, this kind of clearance gauge 10's advantage lies in that the serious clearance gauge piece 13 of certain wearing and tearing can change alone, and need not change whole clearance gauge 10, makes things convenient for the measurement personnel to use, reduces clearance gauge 10's whole use cost.
In one embodiment, the feeler blade 13 is provided with a colored protective layer. As the colored protective layer wears, it marks the caliper blade 13 thickness change.
Specifically, when the feeler gauge piece 13 is used to measure an electronic product, it should be inspected whether the colored protective layer in the feeler gauge piece 13 is worn or not, and the colored protective layer has a striking color different from the color of the feeler gauge piece 13 itself, so that the feeler gauge piece 13 which is worn has a visible mark and the feeler gauge piece 13 is inspected whether there is wear or not. Next, when it is detected that the colored protective layer has worn away and the color of the feeler blade 13 appears due to the exposure of the colored protective layer in a partial region, the measurement is stopped and the feeler blade 13 is replaced.
In one embodiment, the feeler gauge piece 13 is made of plastic material, so as to avoid damaging the measuring object, and the integral structure is light and easy to replace.
