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.

Referring to fig. 1 to 5, an electronic laparoscope lock nut detaching tool is used for an electronic laparoscope, the electronic laparoscope comprises an operating handle a, a lock nut B and an insertion tube C, and the electronic laparoscope lock nut detaching tool comprises: the nut locking device comprises a fixed seat 1, a driven sleeve 2 and a driving sleeve 3, wherein a through hole is formed in the fixed seat 1, a clamping groove 10 for fixing an operating handle A is formed in the front end of the fixed seat 1, specifically, a hand guard on the operating handle A can be clamped into the clamping groove 10, so that the operating handle A is prevented from rotating randomly when a locking nut B is disassembled, and a first external thread 11 connected with the driven sleeve 2 is formed in the rear end of the fixed seat 1; the driven sleeve 2 is internally provided with a through hole, a first internal thread 20 and a second internal thread 21 are arranged in the through hole, the first internal thread 20 is matched with the first external thread 11, the thread pitch and the turning direction of the first internal thread 20 are the same as those of the locking nut B, in the embodiment, the first internal thread 20 and the locking nut B are preferably right-handed threads, and the second internal thread 21 is in threaded connection with the driving sleeve 3; the inside through-hole setting of initiative cover 3, the outside is equipped with second external screw thread 30, second external screw thread 30 and the cooperation of second internal thread 21, the handedness of second external screw thread 30 is opposite with lock nut B, in this implementation, the preferred left-handed screw thread of second external screw thread 30, initiative cover 3 still is equipped with a plurality of locking circular cones 33, locking circular cones 33 evenly set up in the 3 front sides of initiative cover, the hardness of locking circular cones 33 is greater than lock nut B, but locking circular cones 33 butt lock nut B, when locking circular cones 33 butt lock nut B, because the hardness of locking circular cones 33 is greater than lock nut B, so the pointed end of locking circular cones 33 can pierce lock nut B surface, thereby increase friction between the two.

According to the structural description above, when the electronic laparoscope lock nut dismounting tool is used, the operating handle a needs to be fixed in the clamping groove 10 of the fixing seat 1, then the driven sleeve 2 penetrates through the insertion tube C, the driven sleeve 2 is rotated clockwise, the driven sleeve 2 is connected with the fixing seat 1 through the matching of the first internal thread 20 and the first external thread 11, then the driving sleeve 3 penetrates through the insertion tube C, the driving sleeve 3 is rotated anticlockwise, the driving sleeve 3 is connected with the driven sleeve 2 through the matching of the second external thread 30 and the second internal thread 21, the driving sleeve 3 is continuously rotated anticlockwise, the tip of the locking cone 33 can be abutted against the surface of the lock nut B, because the pitch and the rotation direction of the first internal thread 20 are the same as those of the lock nut B, the rotation direction of the second external thread 30 is opposite to that of the lock nut B, and in the process of continuously rotating the driving sleeve 3 anticlockwise, after the maximum engaging force of the first internal thread 20 and the first external thread 11 is broken, driven sleeve 2 can be toward the direction rotation of keeping away from fixing base 1 to drive initiative cover 3 and remove toward same direction, lock nut B then can follow initiative cover 3 and rotate together and remove together under the effect of locking circular cone 33, thereby will lock nut B and dismantle from operating handle A. Generally speaking, the electronic laparoscope lock nut dismounting tool is simple and rapid in dismounting procedure, original devices are not damaged, and cost is saved.

In order to fix the operating handle A in the clamping groove 10 more quickly, the side opening of the fixed seat 1 of the electronic laparoscope dead-lock nut disassembling tool is arranged.

In order to more stably install the driven sleeve 2 and increase the friction between an operator and the driven sleeve 2 in the process of using the electronic laparoscope lock nut disassembling tool, an anti-slip groove 22 is arranged outside the driven sleeve 2 of the electronic laparoscope lock nut disassembling tool.

In order to more laborsavingly detach the dead lock nut B from the operating handle A, the rear end of the driving sleeve 3 of the electronic laparoscope dead lock nut detaching tool is provided with a radial rotating handle 32.

In order to ensure the whole wear resistance and reusability of the electronic laparoscope lock nut dismounting tool, the fixing seat 1, the driven sleeve 2 and the driving sleeve 3 of the electronic laparoscope lock nut dismounting tool are all made of hard rigid materials.
