The corresponding internal thread of line, the socket section and the resiliometer casing thread fitting.
By using above-mentioned technical proposal, the resiliometer casing and positioning tube of thread fitting, connection is closer, secured, makes
Positioning tube do not allow it is easy to be lost.
Preferably, the fixation kit includes being set on socket section and the magnet of resiliometer casing apparent surface.
By using above-mentioned technical proposal, magnet causes the fixation being socketed between section and resiliometer casing to be more convenient, and not
There is a situation where positioning tube is lost.
Preferably, the surface that the supporting section and the attack plane contact is equipped with fixed seat in a ring.
By using above-mentioned technical proposal, fixed seat increases the area that positioning tube is abutted with attack plane so that positioning
Cylinder is more stable to be connected in attack plane, improves the accuracy of test data.
Preferably, the fixed seat is equipped with rubber layer with the surface that the attack plane contacts.
By using above-mentioned technical proposal, rubber layer increases the frictional force between fixed seat and attack plane so that Gu
Reservation is less likely to occur to deviate with attack plane, improves the accuracy of test data.
In conclusion the utility model has the advantages that：
1st, the length of positioning tube is more than the length of elastic stem, ensures that positioning tube can limit resiliometer casing, limits
The offset of resiliometer casing relative positioning cylinder length direction processed avoids the occurrence of the situation hair that positioning tube is detached with resiliometer casing
Raw, positioning tube is socketed on resiliometer casing, the swing of limitation reisilometer when in use so that resiliometer casing is along positioning tube
Length direction is closer or far from movement；During measurement, positioning tube is vertically connected to attack by worker close to the end face of elastic stem one end
Plane, elastic stem is vertical with attack plane at this time, and the resiliometer casing slided later in positioning tube is tested, compared to direct hand
Hold the test of reisilometer, the data precision higher that such mode is tested；
2nd, in cone supporting section cause positioning tube it is more stable be connected to attack plane, positioning tube is less likely to occur to incline
Tiltedly, the accuracy of test is improved indirectly；And the supporting section of cone can play the hand of tester certain protection
Effect reduces and pounds the situation of tester's hand since elastic stem concussion causes attack planar section fragment to come off.

Internal thread 9, socket section 5 coordinated with resiliometer casing 1 by internal and external threads 8, external screw thread 8 be located at resiliometer casing 1 lean on short round
One end of bar 2 is hit, internal thread 9 is located at socket section 5 close to one end of resiliometer casing 1, and the resiliometer casing 1 of thread fitting is with determining
Position cylinder 4, connection are closer, secured so that positioning tube 4 is not allowed easy to be lost.
Supporting section 6 is installed with the surface annular fixed seat parallel with attack plane 3 close to the surface of attack plane 3
11, fixed seat 11 increases the area that positioning tube 4 is abutted with attack plane 3 so that the more stable attack that is connected to of positioning tube 4 is put down
On face 3, the accuracy of test data is improved；Fixed seat 11 is installed with rubber layer 12, rubber close to the surface of attack plane 3
Glue-line 12 increases the frictional force between fixed seat 11 and attack plane 3 so that fixed seat 11 is less likely to occur with attack plane 3
Offset, improves the accuracy of test data.
Specific workflow：During measurement, positioning tube 4 is vertically connected to bullet by worker close to the end face of 3 one end of attack plane
Plane 3 is hit, elastic stem 2 is vertical with attack plane 3 at this time, and the resiliometer casing 1 slided later in positioning tube 4 is tested, phase
Than the test for directly holding reisilometer, the data precision higher that such mode is tested.
Embodiment two：A kind of positioning device of reisilometer, referring to Fig. 3, the difference between this embodiment and the first embodiment lies in：Gu
Determine component difference, the magnet 10 including being fixedly installed in socket 1 apparent surface of section 5 and resiliometer casing, magnet 10 is so that set
The fixation connect between section 5 and resiliometer casing 1 is more convenient, and the situation of the loss of positioning tube 4 is less likely to occur.
Above-described embodiment is only explanation to the utility model, is not the limitation to the utility model, this field
Technical staff can as needed make the present embodiment the modification of no creative contribution after this specification is read, but only
It all to be protected in the right of the utility model by Patent Law.
