[0024] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0025] A multi-functional tachometer includes a tachometer body 1, a detection head 2 at the bottom of the tachometer body 1, a protective cover 3 at the bottom of the tachometer body 1, first connecting components 4 symmetrically arranged on the left and right sides of the protective cover 3, and second connecting components 5 arranged on the lower side of the left and right sides of the tachometer body 1.

[0026] In this embodiment, please refer to Figure 2 The first connecting component 4 includes a connecting seat 401. An adjustment groove 402 is provided on the base surface of the connecting seat 401. A first rotating claw 403 is rotatably provided on the front side inside the connecting seat 401, and a second rotating claw 404 is rotatably provided on the rear side inside the connecting seat 401. A first connecting ear 405 is provided on the front side of the first rotating claw 403, and a second connecting ear 406 is provided on the back side of the second rotating claw 404. A first fixing spring 407 is provided between the bottom of the first connecting ear 405 and the front side of the base surface of the connecting seat 401, and a second fixing spring 408 is provided between the bottom of the second connecting ear 406 and the rear side of the base surface of the connecting seat 401.

[0027] In this embodiment, please refer to Figure 2 The second connecting component 5 includes a connecting plate 501, and a connecting block 502 is provided at the bottom of the connecting plate 501.

[0028] The inner side of the connecting seat 401 is fixedly connected to the left and right sides of the protective cover 3, and the inner end of the connecting plate 501 is fixedly connected to the left and right sides of the tachometer body 1. The connecting block 502 is located inside the first rotating claw 403 and the second rotating claw 404. Limiting holes are provided at the corners of the bottom of the tachometer body 1, and limiting posts are provided at the corners of the base surface of the protective cover 3 corresponding to the limiting holes. Anti-slip textures are provided on the left and right sides of the tachometer body 1. The anti-slip textures can increase the friction with the hand, thereby making it more slip-resistant during use. The tachometer is equipped with a protective cover 3, a first connecting component 4, and a second connecting component 5. After the protective cover 3 is placed below the tachometer body 1, the connecting block 502 enters the interior of the first rotating claw 403 and the second rotating claw 404. The connecting block can be limited by the first fixing spring 407 and the second fixing spring 408, thereby fixing the protective cover 3 to the bottom of the tachometer body 1. The protective cover 3 can protect the detection head 2. When the tachometer body 1 is accidentally dropped, it is not easy to be damaged. The overall device has a simple structure, is easy to operate, and has higher practicality.

[0029] The working process of this utility model is as follows: When using a multi-functional tachometer, a protective cover 3, a first connecting component 4, and a second connecting component 5 are installed on the multi-functional tachometer. After the protective cover 3 is placed below the tachometer body 1, the limiting post enters the interior of the limiting hole. At this time, the connecting block 502 enters the interior of the first rotating claw 403 and the second rotating claw 404. The connecting block 502 can be limited by the first fixing spring 407 and the second fixing spring 408, thereby fixing the protective cover 3 to the bottom of the tachometer body 1. The protective cover 3 can protect the detection head 2. When the tachometer body 1 is accidentally dropped, it is not easy to be damaged. When it is necessary to remove the protective cover 3, it can be removed by simply pulling the protective cover 3 downwards, which is convenient during operation.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
