Problems solved by technology

This invention can solve the problem of difficult fastening screws in some narrow spaces, but the structure of the traditional universal cross joint coupling is complicated, and the manufacturing cost is high. It is difficult to fully function in a small space, and it is not convenient enough; its complicated structure makes it difficult to repair the universal screwdriver through simple repairs after it is damaged, which is not economical

Embodiment 1

[0053] image 3 Shown is a gearless coupling in this embodiment, including a first rotor 2, a second rotor 6 and three connecting rods 8; the end of the first rotor 2 is sleeved with a first turntable 22; the A second turntable 62 is sleeved on the end of the second rotor 6; the connecting rod 8 includes a driving rod 81 and a driven rod 82; the driving rod 81 and the driven rod 82 have an included angle when they are connected; 81 penetrates into the outer edge of the first turntable 22 and slides with the first turntable 22; the driven rod 82 penetrates into the outer edge of the second turntable 62 and slides with the second turntable 62. The distance between the axis of a turntable 22 is equal to the distance between the driven rod 82 and the axial center of the second turntable 62 . The driving rod 81 rotates with the first turntable 22 and the driven rod 82 drives The direction of rotation of the second turntable 62 is the same, and both are clockwise or counter-clockwi...

Embodiment 3

[0079] A method of using a multi-angle screwdriver, the specific steps are as follows: adjust the angle between the driving rod 81 and the driven rod 82, make the movable cutter head 7 close to the screw and fit, and stabilize the first turntable 22 and the second turntable 62. Turn the handle 1 to drive the first rotor 2 and the first turntable 22 at the end to rotate, the first turntable 2 drives the driving rod 81 and the driven rod 82 to rotate, and transmits the torque to the second turntable 62, so that the The second turntable 62 and the second rotor 6 coaxially fixed to the second turntable 62, the movable cutter head 7 coaxially fixed to the second rotor 6, and the screw matched with the movable cutter head 7 rotate, so that the screw is fastened or loose.

Embodiment 4

[0081] The using method of the present invention is as follows:

[0082] A method of using a multi-angle screwdriver, the specific steps are as follows: rotate the handle 1 to drive the movable cutter head 7 to rotate to tighten the bolt; adjust the sleeve adjustment member 4 to make the handle 1 and the movable cutter head 7 at a suitable angle, and then tighten the nut 44 for fixing; rotating the handle 1 drives the first rotor 2 to rotate, the first rotor 2 drives the first turntable 22 to rotate, the first turntable 22 drives the connecting rod 8 to rotate, and the connecting rod 8 drives the second turntable 62 When rotating, the second turntable 62 drives the second rotor 6 to rotate, and the second rotor 6 drives the movable cutter head to rotate; finally, the screw is tightened.

Abstract

The invention discloses a gearless coupling and a multi-angle screwdriver. The gearless coupling of the present invention includes a first rotor, a second rotor and at least one connecting rod; the end of the first rotor is fixedly connected The first turntable; the end of the second rotor is fixedly connected to the second turntable; the connecting rod includes a driving rod and a driven rod; the driving rod and the end of the driven rod are not collinear when connected; the driving rod passes through The driven rod penetrates into the part deviated from the axis of the first turntable and slidably fits with the first turntable; the driven rod penetrates into the part deviated from the axis of the second turntable and slidably fits with the second turntable; for the multi-angle screwdriver of the present invention , comprising a handle and a movable cutter head connected with the handle, the above-mentioned gearless coupling is connected between the handle and the movable cutter head, the handle is fixedly connected with the first rotor; the movable cutter head is coaxially fixed with the second rotor. The invention can change the angle to transmit the torque, and the screwdriver can complete the screw tightening in a narrow space.

Description

technical field [0001] The invention relates to the field of couplings, in particular to a gearless coupling. [0002] The invention also relates to a multi-angle screwdriver. Background technique [0003] Most of the existing universal joints are mainly cross shaft type universal joints and ball cage type universal joints, but the universal joints have complex structures, high manufacturing costs and damage after damage. Difficult to fix problem. [0004] At present, most devices need to use screws during installation. When tightening screws, there is often a problem of narrow operating space, which leads to the interference of ordinary screwdrivers with other devices or mounting brackets, and it is impossible to fasten screws quickly and reliably. This situation greatly increases the difficulty of work for workers and reduces work efficiency, and there may be potential safety hazards when the screws are not fully tightened.
