In order to achieve the above purpose, the present invention provides the following technical solutions: locating pin take-out mechanism has the ladder pole, slidable connection has the striking cover on the ladder pole, the tip of ladder pole is provided with the free bearing, rotatable coupling has the regulation carousel on the free bearing, the equal fixedly connected with thread head all around of regulation carousel, it has four locating holes to open on the regulation carousel, it has the groove of stepping down to open on the free bearing, the groove department of stepping down is provided with bolt assembly, the bottom of striking cover is provided with connecting convex block, it has the connecting hole to open on the connecting convex block, it has two standing grooves to open on the striking cover, the handle has been placed in the standing groove, the handle upper end is provided with the arc lug, threaded connection has spacing lid on the striking cover.

Furthermore, the four thread heads are distributed on the adjusting turntable in an annular array, the positioning holes are arranged corresponding to the thread heads one by one, and the bolt assemblies are arranged corresponding to the positioning holes.

Furthermore, the step rod is in threaded connection with the hinged support, and the connecting lug and the impact sleeve are integrated.

Furthermore, the arc-shaped convex block is welded with the handle, a round hole is formed in the middle of the limiting cover, and the handle is arranged corresponding to the connecting hole.

Furthermore, the diameters of the four thread heads are different.

The utility model has the beneficial effects that: the stepped rod, the impact sleeve, the adjusting rotary table and the threaded head are matched for use, so that the positioning pin can be taken out in a fixed mode according to different specifications, the labor intensity of workers is reduced, and the taking-out efficiency of the positioning pin is improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1-4 shown locating pin take-out mechanism, have ladder pole 1, slidable connection has striking cover 2 on the ladder pole 1, the tip of ladder pole 1 is provided with free bearing 3, rotatable connection has regulation carousel 4 on the free bearing 3, adjust equal fixedly connected with thread head 5 all around of carousel 4, it has four locating holes 401 to open on the regulation carousel 4, it has the groove of stepping down 301 to open on the free bearing 3, the groove of stepping down 301 department is provided with bolt assembly 6, the bottom of striking cover 2 is provided with connection lug 7, it has the connecting hole to open on the connection lug 7, it has two standing grooves 201 to open on the striking cover 2, handle 8 has been placed in the standing groove 201, handle 8 upper end is provided with arc lug 801, striking cover 2 upper end threaded connection has spacing lid 9.

The four screw heads 5 are distributed on the adjusting turntable 4 in an annular array, the positioning holes 401 are in one-to-one correspondence with the screw heads 5, and the bolt assemblies 6 are in correspondence with the positioning holes 401.
