Sealing effect between pars stridulans 42, meanwhile, also improve the sealing effect of the junction of drive end bearing bracket 412 and back end main body 413.
Wall extension 4123 is also connected with preceding connection wall 4124 away from the outer edge of pars stridulans 42, and preceding connection wall 4124 is mainly used
It is connect in back end main body 413；Correspondingly, back end main body 413 has the rear connection wall 4131 extended forward, rear connection wall 4131
First receiving space 411 is surrounded, rear connection wall 4131 and the preceding connection wall 4124 of drive end bearing bracket 412 connect and fix.Wherein, preceding connection
It is provided with fixture block on one in wall 4124 and rear connection wall 4131, another is provided with card slot, passes through matching for fixture block and card slot
Conjunction realization drive end bearing bracket 412 is connected and fixed with back end main body 413, is not only convenient for the assembly of drive end bearing bracket 412 and back end main body 413, but also
Convenient for the disassembly of drive end bearing bracket 412 and back end main body 413.
At this point, the extended loop 434 of resilient support circle 43 specifically supports the wall extension 4123 and back end main body for being located at drive end bearing bracket 412
Between 413 rear connection wall 4131.Wherein, can be set front projection 435 in the front surface of extended loop 434, front projection 435 with
The wall extension 4123 of drive end bearing bracket 412 abuts, in order to the assembly of drive end bearing bracket 412 and back end main body 413；Meanwhile extended loop 434
Rear surface is abutted with the front surface of the rear connection wall 4131 of back end main body 413.
At this point, at least one outer lug 433 in 431 outside of bracing ring main body can be abutted with lower connection wall, it is more by being arranged
Resealing can further increase sealing effect and connection reliability between bracing ring main body 431 and back end main body 413.
In the present embodiment, by it is multi-sealed can further increase it is close between bracing ring main body 431 and pars stridulans 42
Effect and connection reliability are sealed,
Optionally, back end main body 413 is formed in the second accommodation space 413a, the second accommodation space 413a and is provided with circuit
Plate 45, circuit board 45 are electrically connected by conducting wire with oscillator 44, and circuit board 45 is mainly used for controlling the working condition of oscillator 44；Its
In, sealant is filled in the second accommodation space 413a, to realize fixation and the moisture protection to circuit board 45, simultaneously, moreover it is possible to
External water etc. is enough avoided to enter inside it from the rear end of ultrasonic probe 4.
Pars stridulans 42 are influenced in first receiving space 411 in order to avoid the sealant in the second accommodation space 413a enters
Sounding effect, meanwhile, avoid the sealant in the second accommodation space 413a from mixing with the sealant in first receiving space 411,
The rear end of pars stridulans 42 is provided with gasket 46, to pass through gasket 46 for first receiving space 411 and the second accommodation space
413a is completely separated.
