Fig. 3 is the cross-sectional view in the direction A-A in Fig. 1；
Fig. 4 is the elevational cross-sectional view of mounting rack in the utility model embodiment.
Specific embodiment
It is further described below by specific embodiment:
Appended drawing reference in Figure of description includes: positioning table 1, slide bar 2, supporting table 3, locating rack 4, left air bag 5, tracheae
6, mounting rack 7, positioning sleeve 8, support tube 9, the first sliding block 10, the second sliding block 11, bolt 12, air flue 13, gas vent 14.
Embodiment is substantially as shown in Fig. 1: can measure the mouse fixing of depth of needle, including positioning table 1, positioning table
1 upper surface is welded with slide bar 2, and for 1 upper surface of positioning table also integrally formed with supporting table 3,3 upper surface of supporting table is welded with support tube
9, the first sliding block 10 and the second sliding block 11 are slidably fitted on slide bar 2, and the second sliding block 11 is located at the top of the first sliding block 10, such as schemes
Shown in 2, it is provided with tapped through hole on 11 left side wall of the first sliding block 10 and the second sliding block, tapped through hole internal screw thread is connected with positioning bolt
12, be welded with locating rack 4 in 10 right wall of the first sliding block, as shown in figure 3, locating rack 4 is in " Fang " shape, the left inside wall of locating rack 4 and
Left air bag 5 and right air bag are fixedly installed on right inner wall respectively, left 5 right end of air bag and right air bag left end are integrally formed with circular arc
Shape is recessed, and is provided with air flue 13 inside locating rack 4, and air flue 13 is connected to left air bag 5 and right air bag, also fixed on 4 side wall of locating rack
It is connected with tracheae 6,6 one end of tracheae is connected to air flue 13, and 6 other end of tracheae is connected with inflator, and being equipped in tracheae 6 only allows
