Embodiment
As Figure 1-3, a kind of pressure type bolt elongate measuring scale, including hollow sleeve, the sleeve 11 by it is lower extremely
On include successively, gage sleeve pipe 7, gage supervisor 3, the sleeve 11 connects the lower end of gage sleeve pipe 7 by joint 8, described
The upper end of gage sleeve pipe 7 connects the gage and is responsible for 3 lower ends, and the measuring pressure plate 6 is arranged at the gage supervisor 3 close to lower end,
The compression spring 5 is placed on the gage supervisor 3 and between gage supervisor 3 and measuring pressure plate 6, the compression bullet
Measuring pressure plate 6 is pushed down in the lower end of spring 5, and the projection of gage supervisor 3 is withstood in upper end, in order to which the measuring pressure plate 6 is along the gage master
The upper and lower pretension displacement of pipe 3, it is provided with the side of projection one of the gage supervisor 3 of the top of the measuring pressure plate 6 for described in measuring
The micrometric depth gauge 4 of the upper and lower displacement distance of measuring pressure plate 6, gear 12 is provided with the sleeve 11, the gear 12 is by sleeve
The driving of gear extension bar 9 in 11 rotates, the upper end of gear extension bar 9 through joint 8 extend in gage sleeve pipe 7 with connecting rod 2
