The technical solution of the utility model is：
A kind of straight sand machine crossover sub, including straight sand machine joint and transition joint, the rear end of the straight sand machine joint are set
There are cylindrical bore and cylindrical female, the front end of the straight sand machine joint is provided with external thread section and clamp segment, the folder
Tight section is provided with axis hole, also, is circumferentially arranged at intervals with axial bar shaped insertion seam, clamp segment is formed spaced card
Pawl, the outer end outer surface of the claw is round table-like, and the transition joint is provided with endoporus, and the back segment of the endoporus is internal thread
Section, the internal thread segment and the external thread section of the straight sand machine joint match, the leading portion of the endoporus be taper tighten head and with
The outer end of the claw matches.
The axis hole of the clamp segment and the fixing axle of bistrique rear end are clamping, or, axis hole and the emery wheel of the clamp segment connect
The connecting pole of head rear end is clamping, is provided with emery wheel clamping bench and thread segment in the middle part of the emery wheel joint, is screwed on the thread segment
There is locking nut.
Card side is respectively provided with the outer surface of the straight sand machine joint and transition joint, can be fixed with spanner one
Rise, the card side is four directions or six sides.
The beneficial effects of the utility model are：
1. the utility model uses the combination of multiple parts, bistrique can be both installed, emery wheel can be installed again, extended straight
The polishing scope of sand machine, improves operating efficiency, reduces labor intensity, prevent potential safety hazard.
2. the outer end of the straight sand machine joint of the utility model is provided with claw, and has bar shaped insertion seam between claw, easily
Produce deformation and elasticity is big, easily fix the connecting pole of bistrique or emery wheel joint, manipulation is convenient.
3rd, card side is provided with the straight sand machine joint of the utility model and transition joint, is easy to the two connection, and pass through
Spanner fixes, and is connected firmly, security is good.
4th, the straight sand machine joint rear end of the utility model is provided with connecting hole and connection screw thread, can be directly fixed with straight sand machine
Connection, convenient disassembly, in addition, straight sand machine joint and transition joint are provided with taper and tighten portion, can quickly it be formed clamping.
5th, the utility model is designed reasonably, accurate positioning, function be more and easy to use, implementation easy to spread, has good
Economic benefit.
