A digital multimeter usually has an integrated voltage measurement function and can measure DC voltage and AC voltage. It is a commonly used multimeter.

[0003] The existing digital multimeter consists of a display screen, function buttons, a measurement socket and a measurement probe. When in use, the measurement probe is a tool used to connect the circuit under test and perform measurements. It usually includes two probes, red and black, which are used to connect the digital multimeter and the positive and negative electrodes of the circuit under test. The obtained data is displayed on the display screen. However, when debugging, due to the large number of circuits, the staff needs to successively use the measurement probes to detect the positive and negative electrodes of the circuit under test.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing embodiments of the present invention, cross-sectional views of device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0033] Example 1

[0034] Reference Figure 1-Figure 5 , which is the first embodiment of the present utility model, provides a fixing mechanism, which includes a receiving component 100, a clamping component 200 disposed on the receiving component 100, and a mounting component 300 disposed on the receiving component 100;

[0035] The accommodating component 100 includes a housing 101 , which is a digital multimeter, and a probe 102 provided on the housing 101 , which is a measuring probe 102 ;

[0036] The clamping component 200 includes a mounting base 201 disposed outside the housing 101 , with clamping blocks 202 slidably disposed on both sides of the mounting base 201 , and an adjustment component 203 and a positioning component 204 respectively disposed on the mounting base 201 .

[0037] Furthermore, the clamping ends of the two clamping blocks 202 are each provided with a planar groove 205, and the two planar grooves 205 are each provided with an anti-slip pad 206. The planar groove 205 enables the anti-slip pad 206 and the clamping end of the clamping block 202 to be in the same plane. The anti-slip pad 206 increases the friction coefficient of the clamping of the clamping block 202, thereby preventing the clamping block 202 from slipping during clamping.

[0038] Furthermore, the ends of the two clamping blocks 202 are both wedge-shaped. When the clamping blocks 202 need to clamp the voltmeter, the wedge-shaped ends of the clamping blocks 202 facilitate the clamping of the voltmeter by the clamping blocks 202.

[0039] Furthermore, the adjustment assembly 203 includes a strip groove 203 a provided on the mounting seat 201 , a sliding ring 203 b is slidably provided on the strip groove 203 a , and the strip groove 203 a guides the sliding ring 203 b .

[0040] Furthermore, a spring 207 is commonly connected to the corresponding surfaces of the clamping block 202 and the mounting seat 201. The elasticity of the spring 207 drives the clamping block 202 to clamp the voltmeter. When the voltmeter is not clamped, the elasticity of the spring 207 drives the clamping block 202 to reset.

[0041] Furthermore, the inner side of the sliding ring 203b and the outer side of the probe 102 are both provided with threads, and the sliding ring 203b is threadedly connected to the probe 102. The probe 102 is threadedly connected to the sliding ring 203b, such as Figure 4 As shown, when the position of the sliding ring 203 b on the probe 102 needs to be adjusted, the sliding ring 203 b only needs to be rotated so that the sliding ring 203 b slides along the threads on the surface of the probe 102 .

[0042] When in use, the sliding ring 203b is threadedly connected to a probe 102, and then the clamping block 202 is clamped on the shell 101. The elasticity of the spring 1 207 drives the clamping block 202 to be limited on the voltmeter, and then the mounting seat 201 and the probe 102 are both positioned on the surface of the voltmeter. The position of the sliding ring 203b in the strip groove 203a is adjusted by sliding so that the probe 102 on the sliding ring 203b is aligned with the electrode on the voltmeter, so that one probe 102 is fixed on the electrode of the voltmeter, and then only one hand is needed to use the other probe 102 to check the electrodes of multiple voltmeters in succession. In this way, the staff only needs one hand to operate, thereby improving work efficiency.

[0043] Example 2

[0044] Reference Figures 1-6 , which is the second embodiment of the present utility model. This embodiment is different from the first embodiment in that: the positioning component 204 includes a plurality of grooves 204a arranged on the sliding ring 203b, and balls 204b are slidably arranged in the plurality of grooves 204a. The grooves 204a and the balls 204b are connected by a second spring 204c. A plurality of limiting holes 204d are provided on the strip groove 203a. When the sliding ring 203b slides, the balls 204b on the sliding ring 203b are successively engaged with the limiting holes 204d, and the elasticity of the second spring 204c drives the balls 204b to engage with the limiting holes 204d.

[0045] Furthermore, the limiting hole 204d is adapted to the ball 204b, and the limiting hole 204d and the ball 204b are adapted to position the sliding ring 203b on the strip groove 203a, thereby preventing the probe 102 from being offset due to the sliding of the sliding ring 203b when the probe 102 is positioned on the electrode of the voltmeter, thereby preventing the probe 102 from being offset when contacting the electrode of the voltmeter.

[0046] The remaining structures are the same as those of Example 1.

[0047] During use, the positioning assembly 204 positions the slip ring 203b to prevent the probe 102 from being deflected when the probe 102 is positioned on the electrode of the voltmeter due to the sliding of the slip ring 203b, thereby preventing the probe 102 from being deflected when contacting the electrode of the voltmeter.

[0048] Example 3

[0049] Reference Figures 1-6 , which is the third embodiment of the present utility model. This embodiment is different from the second embodiment in that: the mounting component 300 includes two matching holes 301 provided on the housing 101, and the mounting seat 201 is provided with two clamping blocks 302. The clamping blocks 302 are adapted to the matching holes 301. The mounting seat 201 is fixed to the housing 101 through the engagement between the matching holes 301 and the clamping blocks 302. Figure 2 The housing 101 is fixed in the voltmeter cabinet by the clamping block 202, and then the electrodes of the voltmeter are inspected by the two probes 102. This is convenient for users to observe, compared with the existing observation method of placing it on the ground.

[0050] Furthermore, magnets 303 are provided on the corresponding surfaces of the block 302 and the matching hole 301, and the block 302 is quickly engaged with the matching hole 301 through the magnet 303. The attraction between opposite poles of the magnet 303 prevents the block 302 and the matching hole 301 from being released from the limit during use.

[0051] The remaining structures are the same as those of Example 2.

[0052] Working principle:

[0053] When in use, the sliding ring 203b is threadedly connected to a probe 102, and then the clamping block 202 is clamped on the housing 101. The elasticity of the spring 1 207 drives the clamping block 202 to be limited on the voltmeter, and then the mounting base 201 and the probe 102 are both positioned on the surface of the voltmeter. The position of the sliding ring 203b in the strip groove 203a is slidably adjusted so that the probe 102 on the sliding ring 203b is aligned with the electrode on the voltmeter, so that one probe 102 is fixed on the voltmeter, and then only one hand is needed to use the other probe 102 to check multiple electrodes in succession, so that the staff only needs one hand to operate; when it is inconvenient to observe in the voltmeter cabinet, the mounting base 201 is fixed on the housing 101 through the matching hole 301 and the clamping block 302, and then the housing 101 is fixed in the voltmeter cabinet through the clamping block 202, and then the electrodes of the voltmeter are checked by the two probes 102, which is convenient for the user to observe.

[0054] Example 4, with reference to Figure 7, which is the fourth embodiment of the present utility model, provides a meter body 400 arranged on the top side of the shell 101, a knob 401 arranged on the shell 101 for rotating, and a terminal 402 arranged on the bottom side of the shell 101.

[0055] Usage process: The measured value of the data is displayed through the meter body 400, which is convenient for the user to record the data. The knob 401 allows the user to select the required unit of voltage, current or resistance, which can be used for different devices. Terminal 402 is used to connect to the probe 102 of the circuit under test. The data is fed back through the probe 102 and displayed through the meter body 400.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
