Detailed Description

The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.

1-2, the fault detection device provided by the utility model comprises a universal meter main body 1 and a meter pen 2 connected with the universal meter main body 1, wherein a protective piece is arranged at the meter pen 2;

in use, the guard has a first state and a second state;

the first state is that the protective piece is positioned at the nib of the watch pen 2;

the second state is that the protection piece releases the protection of the nib of the stylus 2.

In an alternative embodiment, in order to protect the nib of the stylus 2 from accidental touch damage, the protecting member comprises a sleeve 3, a limiting ring 4 and a spring 5, wherein the limiting ring 4 is fixedly sleeved on the stylus 2, the sleeve 3 is positioned at the periphery of the nib of the stylus 2, the spring 5 is movably sleeved at the periphery of the stylus 2, one end of the spring 5 is fixedly connected with the limiting ring 4, and the other end of the spring 5 is fixedly connected with the inner wall of the sleeve 3.

It should be noted that, the sleeve 3 is moved along the length direction of the stylus 2, so that the limiting ring 4 continuously increases the depth inside the sleeve 3, compresses the spring 5, and the compressed spring 5 has resilience, so as to be beneficial to driving the sleeve 3 to recover.

In an alternative embodiment, the end of sleeve 3 remote from stop collar 4 is closed, which forms a through hole for stylus 2 to pass through.
