The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In the description of the present invention, it is to be understood that the terms "left", "right", "front", "back", "top", "bottom", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 to 3, a tool for quickly mounting a stud includes an end cover 1, a threaded head 2, an abutting head 3, a first threaded sleeve 4, and a second threaded sleeve 5.

The end cover 1 is sleeved on the outer side of the threaded head 2 and is in sliding connection with the threaded head 2.

The top end of the screw head 2 is provided with a transmission hole 21, the outer side wall of the screw head 2 is provided with an annular flange 22 and an external thread, and the annular flange 22 is fixedly arranged above the external thread. On the basis of the technical scheme, the transmission hole 21 is square. The transmission hole 21 is formed in the top of the threaded head 2, so that the assembly tool can be suitable for assembling a pneumatic wrench or a pneumatic ratchet wrench, and the installation efficiency of the stud 6 is greatly improved.

As shown in fig. 3, the abutment head 3 is provided at the bottom of the screw head 2 and abuts against the tip of the stud 6. On the basis of the technical scheme, the abutting joint 3 and the thread head 2 are connected in a clamping or threaded mode. On the basis of the technical scheme, the abutting head 3 is provided with a spherical shape or a conical shape. Because the top of stud 6 is mostly uneven terminal surface in actual assembly process, area of contact is big to frictional force is great. Therefore, the spherical or conical abutting head 3 is arranged at the lower end of the threaded head 2, so that the contact area between the spherical or conical abutting head and the top end of the stud 6 can be reduced, the friction force is effectively reduced, the abutting head 3 and the stud 6 are easy to separate in the assembling process, and the assembling efficiency is improved.

The first thread bush 4 is movably sleeved on the outer side of the thread head 2 and is fixedly connected below the end cover 1. On the basis of the technical scheme, the inner wall of the first threaded sleeve 4 is provided with a limiting table 41, the limiting table 41 and the bottom end of the end cover 1 form a limiting groove 7, and the annular flange 22 is in sliding connection with the limiting groove 7. On the basis of the technical scheme, the inner wall of the first threaded sleeve 4 is provided with an internal thread, and the internal thread is arranged below the limiting table 41 and is matched with the external thread of the threaded head 2. The annular flange 22 on the screw head 2 is matched with the limiting groove 7 for use, so that the screw head 2 can drive the whole tool to rotate in the assembling process, and efficient assembling is realized.

The second threaded sleeve 5 is fixedly connected below the first threaded sleeve 4, and the inner wall of the second threaded sleeve 5 is in threaded connection with one end of the stud 6. Through setting up second thread bush 5, can change according to the specification of the stud 6 of actual assembly, it is nimble convenient to use, and application scope is extensive.

On the basis of the technical scheme, the end cover 1 is fixedly connected with the first threaded sleeve 4, and the first threaded sleeve 4 and the second threaded sleeve 5 through the fasteners 8. Fix end cover 1 and first thread bush 4, first thread bush 4 and second thread bush 5 through fastener 8, can guarantee the structural stability of frock in the assembling process, still conveniently change the specification of second thread bush 5 according to actual assembly demand simultaneously.

On the basis of the technical scheme, the first threaded sleeve 4 and the second threaded sleeve 5 are arranged into an integrally formed structure. Except that above-mentioned first thread bush 4 and second thread bush 5 carry out fixed connection through fastener 8 can also select to set up first thread bush 4 and second thread bush 5 into integrated into one piece structure, also can not need the fastener to fix promptly, improve the utility model discloses the wholeness of frock.

When the tool works, the tool of the utility model is firstly assembled in advance; then screwing one end of the stud 6 into the internal thread 9 of the machine base, and aligning the other end of the stud with the internal thread of the second thread sleeve 5; inserting a pneumatic wrench or a pneumatic ratchet wrench transmission square head into a transmission hole 21 at the top of the thread head 2, adjusting a pneumatic wrench switch, rotating clockwise, screwing the stud 6 into the second thread sleeve 5, enabling the top end of the stud 6 to be in contact with the abutting head 3 at the lower end of the thread head 2, and abutting the annular flange of the bolt head 2 against the lower end face of the limiting groove; then the tool drives the stud 6 to be completely screwed into the internal thread 9 of the base. After the assembly is finished, the pneumatic wrench is adjusted to be turned on or off, the butting head 3 rotates anticlockwise, and is small in contact area with the top end of the stud 6 due to the fact that the butting head is a smooth ball head or a conical head, friction force is small, and the butting head is preferentially disengaged; then the screw thread head 2 is unscrewed until the annular flange 22 of the screw thread head 2 contacts the upper end face of the limiting groove 7, at the moment, the screw thread head 2 drives the whole tool to rotate anticlockwise, and finally the tool is separated from the double-end stud 6 in a threaded mode, and the tool is taken down.

Therefore, the utility model provides a frock of quick installation double-screw bolt can effectively solve among the prior art assembly operation process loaded down with trivial details, waste time and energy and the low scheduling problem of installation effectiveness, and it is nimble convenient to use, and assembly efficiency is high and application scope is extensive.
