It is that flexible plastic material is made that left arc grip block and right arc clip, which hold plate, left arc grip block and right arc clip Hold that the internal diameter of plate is identical, the centering angle that left arc grip block and right arc clip hold plate is 150 ° -170 °, left arc grip block The left-hand face that right lateral surface and right arc clip hold plate is provided with flexible pad.
It is of the present utility model to be using the course of work using above-mentioned technical proposal;By some pieces of same outside dimensions, end faces Coal petrography sample after docking, is then placed into mounting cylinder by the rock sample test piece polished and the structural plane docking of coal sample test specimen Left arc grip block side, then turns handwheel, and hand wheel rotating drive screw drives right arc clip to hold plate to the left along being moved to the left Mobile, until right arc clip holds plate and left arc grip block is next by coal petrography specimen holder, turning clamp nut makes clamp nut pressure Tight set pipe right-hand member, avoids screw rod from rotating.
Bearing is set in the utility model, can avoid that mounting blocks and right arc clip can be driven to hold plate and turn in screw rod rotation process It is dynamic.It is that flexible plastic material is made, left arc grip block and right arc clip hold plate that left arc grip block and right arc clip, which hold plate, Centering angle be that 150 ° -170 ° and right arc clip are held plate and can moved with left and right adjusting, can so be used for the utility model Be fixedly clamped the coal sample test specimen of various outer diameter, the utility model is had good versatility in the lab.Flexible pad plays Effectively protection coal petrography sample is pressurized what is damaged.
In summary, the utility model is designed reasonably, compact-sized, it is easily operated, it is fixed, suitable for various outer diameter Coal petrography sample fixation, prevented coal petrography sample structure face combination when axial deformation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, rock coal sample structure face of the present utility model combination fastener, including cross section are in rectangular configuration Mounting cylinder 1, the center line of mounting cylinder 1 sets along anterior-posterior horizontal, and the inner left wall of mounting cylinder 1 is fixed with fixed block 2, fixed block 2, which pass on left left sunk screw 3, is connected with the open left arc grip block 4 of right-hand member, and the right side of mounting cylinder 1 is provided with manual clamping Device.
Manual clamper holds plate 6, sleeve pipe 7, screw rod 8 and mounting blocks 9 including right arc clip, and right arc clip holds plate 6 and installation Block 9 is located inside mounting cylinder 1, and right arc clip is held the left end opening of plate 6 and is oppositely arranged with left arc grip block 4 or so, installs The right flank that block 9 holds plate 6 with right arc clip is fixedly connected by right sunk screw 10, and sleeve pipe 7, which is fixed, is located at the right side of mounting cylinder 1, The center line of sleeve pipe 7 is set along left and right horizontal, and the right side opening of mounting cylinder 1 is provided with through hole corresponding with the endoporus of sleeve pipe 7, and screw rod 8 stretches into simultaneously It is threaded in sleeve pipe 7 and through hole, passes through in mounting blocks 9 provided with the bearing chamber that right-hand member is open, the left end of screw rod 8 installed in bearing Indoor bearing 11 is rotatablely connected with mounting blocks 9, and the clamp nut contacted with the right-hand member top pressure of sleeve pipe 7 is threaded with screw rod 8 12, the right-hand member of screw rod 8 is provided with handwheel 13.
