Preferably, the second thread 13 on the central screw 9 is a reverse thread, so that the driving sleeve and the jacking sleeve can advance and retreat in the same direction, and the jacking sleeve and the central screw can rotate relatively.
Before the invention is used, the internal gear 18 is selected according to the thread pitch of the bolt, and then the bolt is inserted into the first through hole 19 and the second blind hole 20, so that the effect of adjusting the gear transmission ratio is realized.
When the lifting screw rod 2 is used, the rotating part 8 of the lifting screw rod 2 is rotated through the hexagonal open-ended wrench, and when the rotating part 8 rotates, the lifting screw rod 2 can ascend or descend relative to the base 1. When 2 spiral risers of lifting screw rod rise, drive supporting seat 3, top tight cover 12, drive cover 4 and carry out 5 spiral risers in proper order, the tip of bolt is pressed close to the assembly and disassembly tools wholly, twists through hexagonal opening spanner then and moves connecting portion 15, goes up connecting portion 15 drive top tight cover 12 top tight drive cover 4 and carry out head 5, then drive carries out 5 rotating bolts of head, reaches the purpose of dismouting.
However, when the bolt is disassembled and assembled, the driving sleeve 4 and the tightening sleeve 12 need to move up and down synchronously, namely, the tightening sleeve 12 always props against the driving sleeve 4 in the bolt disassembling and assembling process, so that the actuating head 5 is always tightly combined with the head of the bolt and moves forward and backward synchronously, the bolt head is prevented from being damaged due to slipping or stress deflection, and the normal and effective transmission of the torsional moment is ensured.
Based on the principle of gear speed change transmission, when the driving sleeve 4 rotates, on one hand, the driving execution head 5 is driven to rotate the bolt, so that the aim of dismounting is fulfilled; on the other hand, the internal gear 18 can be driven to rotate, and then the tightening sleeve 12 is driven to rotate around the central screw rod 9 of the support base 3 through the planet wheel 11, so that the tightening sleeve 12 can move up and down, and the driving sleeve 4 and the tightening sleeve 12 can rotate asynchronously due to the gear transmission ratio.
Preferably, the center of the base 1 is a threaded hole, a central thread 25 is arranged in the threaded hole, the central thread 25 is meshed with the first thread 6, the base 1 is in threaded connection with the lifting screw 2 through the threaded hole, and when the lifting screw 2 rotates, the central thread 25 is meshed with the first thread 6, so that the effect of driving the lifting screw 2 to ascend or descend relative to the base 1 is achieved. The tightening sleeve 12 is internally provided with a third thread 29, and the third thread 29 is meshed with the second thread 13.
In detail, twist the rotation portion 8 of lifting screw 2 through hexagonal open-ended wrench, rotation portion 8 realizes the effect that the axial rises or descends relative to base 1 under the effect of first screw thread 6, when lifting screw 2 goes up and down, drives supporting seat 3, top tight cover 12, driving sleeve 4 and execution head 5 in proper order and rises for the whole tip of pressing close to the bolt of assembly and disassembly tools. Then, the driving sleeve 4 is screwed by a hexagonal open-ended wrench, and when the driving sleeve 4 rotates, on one hand, the actuating head 5 is driven by the upper connecting part 15 to rotate the bolt, so that the aim of disassembling and assembling the bolt is fulfilled; on the other hand, the internal gear 18 is driven to rotate through the lower connecting part 16, and as the internal gear 18 is meshed with the planet gears 11, the planet gears 11 rotate when the internal gear 18 rotates; because the planet wheel 11 is meshed with the first gear 14, when the planet wheel 11 rotates, the first gear 14 is driven to rotate, then the tightening sleeve 12 is driven to rotate through the rotation of the first gear 14, when the tightening sleeve 12 rotates, the tightening sleeve 12 goes up and down on the central screw 9 under the action of the second thread 13, the effect of further tightening the driving sleeve 4 and the execution head 5 through the tightening sleeve 12 is achieved, through the meshing among the planet wheel 11, the first gear 14 and the inner gear 18, when the driving sleeve 4 rotates, the effect of advancing and retreating of the execution head 5 and the bolt with equal pitch is achieved based on the principle of gear variable speed transmission, the execution head 5 is always tightly combined with the bolt head and synchronously advanced and retreated, the damage to the bolt head caused by slipping or force deflection is avoided, and the normal and effective transmission of the torsion moment is ensured. Meanwhile, the invention uses the hexagonal open-ended wrench in a matched manner, so that the disassembling and fastening mode of the screwdriver or the wrench which is difficult to normally implement in a narrow space is uniformly converted into the fastening mode of the hexagonal open-ended wrench which is convenient to operate in a wide space, and the problem that the situation that the screwdriver or the wrench is inclined to twist and is easy to twist is often caused because a common screwdriver or the wrench cannot be normally used due to the fact that enough unfolding space is not available in the disassembling and assembling process in the prior art is solved.
As shown in fig. 20, when the bolt is disassembled, the internal gear 18 is selected according to the thread pitch of the bolt to determine the gear transmission ratio, the bolt passes through the first through hole 19 and the second blind hole 20, so that the driving sleeve 4 and the internal gear 18 can rotate synchronously, then a certain number of threads are reserved at the lower part of the tightening sleeve 12, namely a certain space is reserved at the lower part of the driving sleeve 4, then the lifting screw 2 is rotated by using a hexagonal open-ended wrench to integrally lift the supporting seat 3, the tightening sleeve 12, the driving sleeve 4 and the execution head 5 along the axial direction until the execution head 5 tightly pushes the head of the bolt, and then the driving sleeve 4 is screwed by using the hexagonal open-ended wrench along the bolt loosening direction to drive the execution head 5 to rotate, so that the bolt is gradually loosened until the bolt is disassembled.
As shown in figure 21, when a bolt is installed, an internal gear 18 is selected according to the thread pitch of the bolt to determine the gear transmission ratio, a bolt penetrates through a first through hole 19 and a second blind hole 20, so that a driving sleeve 4 and the internal gear 18 can rotate synchronously, then a hexagonal open-ended wrench is used for rotating a lifting screw 2 to integrally lift a supporting seat 3, a jacking sleeve 12, the driving sleeve 4, an execution head 5 and the like along the axial direction until the execution head 5 jacks the head of the bolt, then the driving sleeve 4 is screwed by the hexagonal open-ended wrench along the bolt screwing direction to drive the execution head 5 to rotate, so that the bolt is gradually fastened in place, and after the bolt is fastened in place, the tool can be detached by clamping a base 1 and rotating the lifting screw 2 by the wrench.
