Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
Referring to fig. 1-4, the present invention provides the following technical solutions: the utility model provides a portable stock verifying attachment, including hydraulic pump 1, end cover 2 is installed to the preceding terminal surface screw thread of hydraulic pump 1, one side screw thread that hydraulic pump 1 was kept away from to the medial surface of end cover 2 is installed fixed pincers 3, fixed pincers 3 include annular body 4 and centre bore 5, centre bore 5 includes face of cylinder 6 and round platform 7, T type groove 8 has been seted up to the inner wall of round platform 7, the medial surface slidable mounting in T type groove 8 has movable clamp 9, movable clamp 9 includes batter post 10, splint 11 and with T type groove 8 complex slider 12, one side that batter post 10 was kept away from to splint 11's surface is provided with protruding crowd 13 of toper.
In this embodiment, hydraulic pump 1 has hollow structure, can supply the stock to pass, it removes to drive fixed pincers 3 during the operation, thereby accomplish the inspection of drawing of stock, because prior art, no longer giving details here, end cover 2 can avoid the activity to press from both sides 9 to fall out from T type groove 8 with fixed pincers 3 equipment back, play limiting displacement, the setting up of end cover 2 makes the dismouting of fixed pincers 3 on hydraulic pump 1 more convenient, convenient the change, fixed pincers 3 are used for fixed stock, and fixed pincers 3 need not manual regulation in the use, clamping to the stock is more stable, it is more convenient to use, and spare part still less, the production cost is reduced, and is more practical.
