[0026] With reference to Figure 1 , Figure 2 and Figure 4 , the utility model provides an embodiment: assembly type oscilloscope assembly probe, including oscilloscope body 1, two interface mechanisms 2 and two joint mechanisms 3, oscilloscope body 1 includes body 101, two interface mechanisms 2 all include cylindrical groove 201, connecting ball groove block 202, a plurality of buffer blocks 203, protective cover 205 and annular groove 206, two joint mechanisms 3 all include connecting ball head 301, wire head 302 and protective layer 304, two cylindrical grooves 201 are respectively symmetrically opened to the lower position of one side of the front end of body 101, the rear end of two connecting ball groove blocks 202 is fixed to the rear end center of two cylindrical grooves 201 respectively, two connecting ball heads 301 are respectively clamped and set to the inside of the spherical recess of the front end of two connecting ball groove blocks 202.

[0027] Specifically, the oscilloscope body 1 provides good installation position for two connecting ball heads 301 and two protective layers 304 in two joint mechanisms 3 through two cylindrical grooves 201 and two annular grooves 206 in two interface mechanisms 2, two connecting ball groove blocks 202 in two interface mechanisms 2 are respectively and stably and firmly electrically connected with the processing unit built-in in the body 101 in the oscilloscope body 1 and two connecting ball heads 301 in two joint mechanisms 3, and provide stable and firm electrical connection between the probe and the oscilloscope.

[0028] With reference to Figure 3The upper end of the machine body 101 is fixedly provided with a handle 102, and the upper middle of the front end of the machine body 101 is fixedly provided with a display screen. A plurality of keys 103 and a plurality of knobs 104 are fixedly arranged around the display screen at the front end of the machine body 101.

[0029] Specifically, in use, according to actual needs, the user can operate related operations through the plurality of keys 103 and the plurality of knobs 104 in combination with the information displayed on the display screen. The handle 102 facilitates the user to move the position of the oscilloscope.

[0030] Referring to Figure 4 and Figure 5 Two annular grooves 206 are respectively formed in the outer circle of the two cylindrical grooves 201 of the machine body 101. The rear ends of the two protective covers 205 are fixedly arranged at the edge positions of the front ends of the two cylindrical grooves 201. The two protective covers 205 are both circular rings. The diameters of the inner holes of the two protective covers 205 are both greater than the diameter of the two connecting ball heads 301. The column walls of the two annular grooves 206 are both fixedly provided with a plurality of spring dampers 204 in a central symmetry. Two groups of the plurality of spring dampers 204 are respectively fixedly connected to the outer middle positions of the plurality of buffer blocks 203 in front of and behind. The diameters of the internal passages surrounded by the plurality of buffer blocks 203 in each cylindrical groove 201 gradually increase from front to back. The diameters of the rear ends of the internal passages surrounded by the plurality of buffer blocks 203 in each cylindrical groove 201 are less than the diameter of the two connecting ball heads 301. The diameters of the front ends of the internal passages surrounded by the plurality of buffer blocks 203 in each cylindrical groove 201 are slightly greater than the diameter of the two wire heads 302.

[0031] Specifically, in use, according to actual needs, the user can sequentially insert the connecting ball head 301 and the wire head 302 in the joint mechanism 3 into the internal passage formed by the plurality of buffer blocks 203 in the cylindrical groove 201 in the interface mechanism 2. The spherical design of the connecting ball head 301 facilitates the insertion from the front end of the internal passage. During the insertion of the connecting ball head 301, the plurality of buffer blocks 203 are expanded outward under pressure, and the plurality of spring dampers 204 are compressed and shortened. The expansion of the diameter of the internal passage facilitates the insertion and passing of the connecting ball head 301.

[0032] When the connecting ball head 301 completely passes through the internal passage, the rear end of the connecting ball head 301 is clamped and arranged into the spherical recess at the front end of the connecting ball groove block 202. At this time, the wire head 302 connected to the front end of the connecting ball head 301 stays in the internal passage. Since the diameter of the wire head 302 is less than the diameter of the connecting ball head 301, the plurality of spring dampers 204 restore the deformation, reset the plurality of buffer blocks 203, and leave a certain narrow space between the internal passage and the outer wall of the wire head 302.

[0033] Even if the probe is moved during use, the rear end of the internal passage is smaller in diameter than the connecting ball head 301, so the connecting ball head 301 cannot easily come off, and the plurality of spring dampers 204 and the buffer block 203 provide good limiting, supporting and resetting functions for the wire head 302 that moves eccentrically with the connecting ball head 301 as the center.

[0034] With reference to Figure 4 And Figure 6 The rear end centers of the two wire heads 302 are fixedly arranged at the front end centers of the two connecting ball heads 301, and the outer walls of the two wire heads 302 are each covered and fixedly provided with a wire sheath 303. The outer walls of the two wire sheaths 303 are each covered and fixedly provided with a protective layer 304 near the two cylindrical grooves 201, and the front end edges of the two protective layers 304 are each fixedly provided with a cover 305, and the rear ends of the two protective layers 304 are each clamped into the interior of the two annular grooves 206.

[0035] Specifically, the wire sheath 303 provides good protection and insulation for the wire head 302, the rear end of the protective layer 304 is well clamped into the annular groove 206, which provides good protection for the connection and effectively enhances the stability of the connection.

[0036] Working principle: in use, according to actual needs, the user can insert the connecting ball head 301 and the wire head 302 in the joint mechanism 3 into the internal passage formed by the plurality of buffer blocks 203 in the interface mechanism 2, and the spherical design of the connecting ball head 301 facilitates insertion from the front end of the internal passage. During the insertion of the connecting ball head 301, the plurality of buffer blocks 203 are expanded outward under pressure, and the plurality of spring dampers 204 are compressed and shortened, and the diameter of the internal passage is expanded to facilitate the insertion and passage of the connecting ball head 301.

[0037] Then, when the connecting ball head 301 completely passes through the internal passage, the rear end of the connecting ball head 301 is clamped into the spherical groove at the front end of the connecting ball groove block 202, and at this time the wire head 302 connected to the front end of the connecting ball head 301 stays in the internal passage. Since the diameter of the wire head 302 is smaller than that of the connecting ball head 301, the plurality of spring dampers 204 restore the deformation and reset the plurality of buffer blocks 203, leaving a small space between the internal passage and the outer wall of the wire head 302.

[0038] Secondly, even if the probe is moved during use, the rear end of the internal passage is smaller in diameter than the connecting ball head 301, so the connecting ball head 301 cannot easily come off, and the plurality of spring dampers 204 and the buffer block 203 provide good limiting, supporting and resetting functions for the wire head 302 that moves eccentrically with the connecting ball head 301 as the center.

[0039] Finally, the wire skin layer 303 provides good protection and insulation for the wire head 302, and the back end of the protection layer 304 is well clamped into the annular groove 206, thereby providing good protection for the connection and effectively enhancing the stability of the connection.

[0040] Finally, it should be noted that the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing detailed description of the application has been made, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
