Arc-shaped grooves 102a and straight grooves 102b are formed in the outer side of the rotary cylinder 102, and the arc-shaped grooves 102a and the straight grooves 102b are alternately arranged;
the straight slots 102b are axially arranged along the rotary cylinder 102, and the arc-shaped slots 102a connect two adjacent straight slots 102b end to end.
It should be noted that the connecting portion of the arc-shaped slot 102a and the straight slot 102b is a cliff-type structure, which is a height difference between the connecting portions of the two, and the heights are orderly along the same direction; referring to fig. 5, the arc-shaped groove 102a is high to low from the straight groove 102b at b, the arc-shaped groove 102b is high to low from the straight groove 102a at a, and the arc-shaped groove 102a is high to low from the straight groove 102b at c, i.e. the circumferential direction transition from b to a is high to low from b to c.

one end of the dial shaft 103c-3 is disposed in the straight groove 102 b.
When the control rod 103 is pushed in the direction 1 indicated by the arrow shown in fig. 5, the shifting shaft 103c-3 slides from the position b to the position a in the straight slot 102b, the rotating cylinder 102 is unchanged in the process, the control rod 103 is pulled back in the direction 2 after the position a is reached, the shifting shaft 103c-3 touches the corner where the straight slot 102b and the arc-shaped slot 102a meet when the position a returns, enters the arc-shaped slot 102a, meanwhile, because the arc-shaped slot 102a at a is lower than the straight slot 102b, the shifting shaft 103c-3 will move along the arc-shaped slot 102a during the return stroke, since the trigger end 103c is limited and cannot rotate, the rotary drum 102 will rotate according to the position change of the dial shaft 103c-3 in the arc-shaped groove 102a until the dial shaft 103c-3 reaches c, which is similar to a, except that the dial shaft 103c-3 reaches c and enters one side of the straight groove 102 b; pushing in direction 1 again will repeat the above action.
That is, once the lever 103 is pushed, the rotary cylinder 102 is not operated, and once the lever is pulled back, the rotary cylinder 102 is rotated.
In the present embodiment, the rotary cylinder 102 is provided with four pairs of arc-shaped grooves 102a and straight grooves 102b, i.e. the arc-shaped grooves 102a occupy a quarter of a circle in the circumferential direction, i.e. the rotary cylinder 102 rotates 90 ° every time a push-pull action is performed.
It should be noted that there is an arc edge at a, so that the shift shaft 103c-3 shifts from being at the side of the straight slot 102b to being at the side of the arc slot 102a when moving to a in the direction 1, so as to move into the arc slot 102a when the shift shaft 103c-3 returns again in the direction 2.
The pushing spring 103c-2 pushes against the shifting shaft 103c-3, so that the shifting shaft 103c-3 adapts to the height change between the straight slot 102b and the arc slot 102a, one end of the shifting shaft 103c-2 is kept in the straight slot 102b or the arc slot 102a, and the other end is kept in the limiting hole 103 c-1.
The end of the rotary cylinder 102 is provided with a first volute projection 102c and a second volute projection 102d, and the second volute projection 102d is arranged above the first volute projection 102 c;
the second volute projection 102d has a larger radius than the corresponding radius of the first volute projection 102 c.
When the rotary cylinder 102 rotates, the first spiral protrusion 102c and the second spiral protrusion 102d rotate synchronously, and it should be noted that two pairs of the first spiral protrusion 102c and the second spiral protrusion 102d, which occupy 180 ° each, are disposed on the rotary cylinder 102 in a central symmetry manner.
Example 2
Referring to fig. 1 to 8, the difference between the present embodiment and the previous embodiment is that the blocking member 302 includes a baffle 302a and a trigger plate 302b, the trigger plate 302b is disposed on the side of the baffle 302a, and the end of the trigger plate 302b contacts with the first volute protrusion 102 c;
the baffle 302a is connected with the spacing rod 101 through a shaft, and a first spring 101f is further arranged on the spacing rod 101 and connected with the baffle 302 a.
The side surface of the first spiral protrusion 102c is spiral, that is, when the first spiral protrusion 102c rotates, the position of the trigger plate 302b and the contact point thereof will be away from the center line of the rotary cylinder 102, that is, the trigger plate 302b is pushed outwards, and the baffle 302a is turned over, and the first spring 101f tends to close the baffle 302 a.
An arc plate 302c is arranged at the end part of the baffle plate 302a, and one end of the arc plate 302c is connected with the baffle plate 302a through a shaft;
the end of the arc plate 302c is provided with a first hook 302d, the second hook 301 is provided with a second hook 302e, and the position of the first hook 302d corresponds to the position of the second hook 302 e.
The trigger plate 302b is provided with a first guide rod 302f and a connecting rod 302g, the guide rod 302f is connected with the trigger plate 302b through a shaft, the connecting rod 302g is connected with the first guide rod 302f and the arc plate 302c, and the guide rod 302f is in contact with the second vortex-shaped bump 102 d;
the baffle 302a is further provided with a second spring 302h, and the second spring 302h is connected with the arc plate 302 c.
The second spring 302h tends to keep the arc plate 302c horizontal when the shutter 302a is closed, while the first hook 302d engages with the second hook 302 e.
The arc plate 302c serves to enclose the cable within its enclosure with the second hook 301,
the second spring 302h has a certain elastic force enough to support the weight of the cable placed on the arc plate 302 c.
It should be noted that the elastic coefficient of the first spring 101f is larger than that of the second spring 302 h.
The radius of the second volute projection 102d is larger than the radius corresponding to the first volute projection 102c, which is embodied in that during the rotation of the rotary cylinder 102, the change dimension of the pilot rod 302f in contact with the side surface of the second volute projection 102d is larger than that of the trigger plate 302b in contact with the first volute projection 102c, that is, the change rate of the pilot rod 302f pushed outwards is larger than that of the trigger plate 302b when the rotary cylinder rotates by the same angle.
Note that one end of the radius end of the second spiral protrusion 102d and the first spiral protrusion 102c is a starting point, and the other end of the radius length is an end point, and the radius gradually increases from the starting point to the end point, and since the rotation direction of the rotary cylinder 102 is constant, the rotation direction is counterclockwise in this embodiment, referring to fig. 5, during the rotation of the rotary cylinder 102, the shape of the first spiral protrusion 102c is set so that the trigger plate 302b undergoes a cycle from the starting point to the end point.
Specifically, the trigger plate 302b is pushed outward when the rotary cylinder 102 rotates, but at the same time, the first guide rod 302f always acts before the trigger plate 302b, so that the pilot rod 302f is pushed by the second spiral protrusion 102d before the baffle plate 302a is pushed and overturned by the first spiral protrusion 102 c.
The guide rod 302f moves to drive the connecting rod 302g and the arc plate 302c, so that the first hook 302d is separated from the second hook 302e, and then the blocking plate 302a can be pushed open.
If the rotary cylinder 102 is not rotated, the first hook 302d is engaged with the second hook 302e, and the baffle 302a cannot be opened by turning.
To sum up, initially, the first spring 101f connects the baffle 302a to seal the entrance of the second hook 301, the arc plate 302c engages the first hook 302d with the second hook 302e under the action of the second spring 302h, at this time, the shifting shaft 103c-3 is located in the straight slot 102b, the contact plate 302b and the first guide bar 302f are both located at the position of the starting point 1, at this time, the control lever 103 is pushed and pulled back, the contact plate 302b and the first guide bar 302f move from the starting point 1 to the position of the ending point 1, in this process, the action of the pilot bar 302f precedes the action of the contact plate 302b, so the action of the pilot bar 302f drives the connecting bar 302g to rotate the arc plate 302c, the first hook 302d disengages from the second hook 302e, the baffle 302a flips over the opening, and then the control bar 103 is pushed and pulled once, the contact plate 302b and the first guide bar 302f pass through the ending point 1 and reach the starting point 2, when the opening angle of the baffle 302, the cable can be placed into the second hook 301 when the flap 302a is open, and then the control lever 103 is pulled back into position, i.e. the contact plate 302b and the pilot lever 302f reach the start point 2, and the flap 302a closes the second hook 301 entrance again.
By continuously pushing and pulling the control lever 103, the contact plate 302b and the pilot lever 302f are positioned in a cycle from the start point 1, the end point 1, the start point 2, the end point 2 to the start point 1, and the flap 302a is continuously opened and closed in the process.
This structure ensures that the shutter 103 can be opened and closed only when the control lever 103 is operated to rotate the rotary cylinder 102, and then the second volute projection 102d pushes the first guide bar 302f, and then the first volute projection 102c pushes the contact plate 302b, and the first spring 101f, the second spring 101h, and the engagement of the first hook 302d and the second hook 302e all limit the movement of the shutter 103 at the rest of time.
Another limitation of the present invention is that the force applied during use is push-pull force, which controls the second clamping assembly 300 to connect to the far cable, while the near one controls the first clamping assembly 200 to connect to the near cable by using the rotational force, so that the near cable can be connected without requiring too much movement, the far cable is too laborious to operate by using the rotational force, and it is more convenient to use push-pull force with large movement amplitude.
It should be noted that all the components of the present invention except the spring are made of insulating materials to ensure the safety of use.
