Optionally, a bearing is disposed in the mounting groove of the fixing case 20, and the second end of the rotating shaft 31 is connected to the bearing, so that the second end of the rotating shaft 31 can rotate relative to the fixing case 20, and the second clamping portion 32 and the first clamping portion 2013 can be switched between a clamping state and a disconnecting state, so as to mount and dismount the probe 201.

Referring to fig. 5 and 6, in some embodiments, the clamping mechanism 30 further includes a movable assembly 33, the rotating shaft 31 is provided with a fixing portion 34, a side (i.e. a first side) of the fixed case 20 away from the second mounting hole 22 is provided with a third mounting hole 23, the third mounting hole 23 is communicated with the accommodating space 21, the movable assembly 33 is movably connected to the third mounting hole 23, so that a length of the movable assembly 33 extending into the accommodating space 21 is adjustable, and the movable assembly 33 is used for being in clamping connection with the fixing portion 34 when the second clamping portion 32 is clamped with the first clamping portion 2013.

Thus, by adjusting the length of the movable component 33 extending into the accommodating space 21, the movable component 33 and the fixing portion 34 are switched between the two states of the clamping connection and the disconnection, and by way of example, when the length of the movable component 33 extending into the accommodating space 21 is long enough to enable the movable component 33 to be clamped and connected with the fixing portion 34, the rotating shaft 31 cannot rotate under the limitation of the movable component 33, so that the movement of the second clamping portion 32 can be limited, the first clamping portion 2013 and the second clamping portion 32 are kept in the clamping state, when the detecting head 201 needs to be dismounted from the auxiliary fixing device 100, the movable component 33 moves in the direction away from the accommodating space 21, so that the length of the movable component 33 extending into the accommodating space 21 is shortened to be disconnected with the fixing portion 34, and at the moment, the rotating shaft 31 is not limited, the second clamping portion 32 can be driven to rotate, and therefore the second clamping portion 32 is disconnected with the first clamping portion 2013, the limit of the mounting bracket 2012 of the detecting head 201 is relieved, and the mounting bracket 2012 of the detecting head 201 is convenient to dismount from the accommodating space 21.

Therefore, when the rotating shaft 31 is rotated to enable the first clamping portion 2013 to be clamped to the second clamping portion 32, the second matching portion 341 rotates to the lower portion of the first matching portion 332 along with the rotating shaft 31, so that the first matching portion 332 is connected with the first matching portion 332 in a clamping manner, the rotation of the rotating shaft 31 along the circumferential direction is limited while the first clamping portion 2013 is clamped to the second clamping portion 32, and connection reliability of the first clamping portion 2013 and the second clamping portion 32 is improved.

Alternatively, as can be seen from the foregoing, the number of the rotating shaft 31 and the second engaging portion 32 is plural, the second engaging portion 341 is disposed on the rotating shaft 31, and based on this, the number of the first engaging portion 332 and the second engaging portion 341 may be plural, and the plural first engaging portions 332, the plural second engaging portions 341 and the plural rotating shafts 31 are in one-to-one correspondence. In this way, the engagement connection between the plurality of first engagement portions 332 and the plurality of second engagement portions 341 is advantageous in restricting the rotation of each rotation shaft 31, so that the connection reliability between the probe 201 and the auxiliary fixture 100 can be improved.

In this way, when the protection plate 41 receives the external impact force directed to the detecting main body 2011, the protection plate 41 firstly absorbs and damps by utilizing the material property of the protection plate 41, and the external impact force which is not absorbed by the protection plate 41 drives the protection plate 41 to drive the connecting rod 46 and the movable plate 45 to move towards the damping member 43, so as to compress the second elastic member 42 until the movable plate 45 abuts against the damping member 43, and absorb and reduce the external impact force by utilizing the damping member 43, and simultaneously the second elastic member 42 drives the movable plate 45 to reciprocate under the action of the self elastic force, so that the movable plate 45 abuts against the damping member 43 for many times until the external impact force is completely consumed, and at the moment, the protection plate 41 is restored to the free state of the second elastic member 42 without external force under the action of the second elastic member 42, so as to prevent the next external impact.
