The lower end of the transmission slide shaft 5 is connected with the rotating power component 41, and the upper end is inserted in the sliding long hole 63 of the inner cavity of the bidirectional screw rod 6 in a sliding manner. The cross section of the transmission slide shaft 5 is a polygonal structure, and the cross section of the sliding long hole 63 is a polygon matched with the outer side wall of the transmission slide shaft 5, so that the transmission slide shaft 5 and the bidirectional screw rod 6 can slide vertically but cannot rotate relatively, and the rotating power assembly 41 can drive the bidirectional screw rod 6 to rotate through the transmission slide shaft 5.
The inner side wall of the upper sleeve 71 is provided with an internal thread matched with the right-handed thread 62 and is in threaded connection with the upper part of the two-way screw rod 6. The inner side wall of the lower sleeve 72 is provided with an internal thread matched with the left-handed thread 61 and is in threaded connection with the lower part of the bidirectional screw rod 6. Therefore, when the rotary power assembly 41 drives the bidirectional screw rod 6 to rotate through the transmission slide shaft 5, the upper sleeve 71 and the lower sleeve 72 move vertically in opposite directions relative to the bidirectional screw rod 6 at the same time, so that the relative movement distance between the upper sleeve 71 and the lower sleeve 72 is twice as long as the movement distance of the bidirectional screw rod 6 relative to the upper sleeve 71 or the lower sleeve 72, and the required time is only half as long as that of a unidirectional screw rod.
As shown in fig. 1 and 6, the upper sleeve 71 is fixed in the inner cavity of the middle tube 12, and the lower sleeve 72 is fixed in the inner cavity of the inner tube 11, and a common structure of protrusion and notch fit can be adopted to fix and prevent relative rotation between the upper sleeve 71 and the middle tube 12 and between the lower sleeve 72 and the inner tube 11. Therefore, when the bidirectional screw rod 6 rotates, the upper sleeve 71 and the lower sleeve 72 can drive the middle pipe 12 and the inner pipe 11 to simultaneously and vertically move in opposite directions.
In this embodiment, as shown in fig. 2, 5 and 6, a first pulley seat 83 is fixedly disposed on the top of the outer tube 13, and the first pulley seat 83 is provided with a groove for mounting a pulley 86 and a slot for receiving and fixing a pulling wire. A second pulley seat 84 is fixedly arranged at the top of the upper sleeve 71, the second pulley seat 84 is also positioned at the top of the middle pipe 12, and a groove for installing a pulley 88 and a slotted hole for fixing a pull line are arranged on the second pulley seat 84.

One end of the outer tube pulling wire 82 is connected to the slot 64 arranged at the top of the bidirectional spinning rod 6, and the other end of the outer tube pulling wire is sequentially wound around a pulley 88 arranged on the second pulley seat 84 and a pulley 89 arranged at the bottom of the outer tube 13 and then is upwards connected to the slot of the first pulley seat 83. Therefore, the winding utilizes the principle of linkage pulley block, and the pull wire can save labor when pulling the lower nest 22 or the outer pipe 13.
As shown in fig. 4 and 6, the umbrella handle 3 comprises an outer shell 32 and an inner seat 33, an electronic control assembly 42 is further installed at the inner seat 33, the rotating power assembly 41 can comprise a motor and the like, a placing groove 43 for installing a battery is arranged in the umbrella handle 3, and the battery is used for supplying power to the motor. The umbrella handle 3 is also provided with a button 31 for controlling the opening and closing of the umbrella.
As shown in fig. 1, 2 and 3, when the umbrella is opened, the electronic control assembly 42 is pressed by pressing the button 31 on the handle 3 to release electric energy to drive the rotating power assembly 41 to rotate the transmission slide shaft 5 in reverse direction, the transmission slide shaft 5 drives the bidirectional screw rod 6 to rotate in reverse direction, so that the upper sleeve 71 and the lower sleeve 72 move synchronously in a direction away from the middle part of the bidirectional screw rod 6, thereby driving the inner tube 11 to move downwards relative to the bidirectional screw rod 6 and the middle tube 12 to move upwards relative to the bidirectional screw rod 6, because the inner tube 11 is fixed on the handle 3, as a result, the middle tube 12 moves upwards relative to the inner tube 11 by a distance twice the displacement of the bidirectional screw rod 6. In the process, as the distance between the top of the bidirectional screw rod 6 and the top of the middle tube 23 is lengthened, the outer tube pull wire 82 pulls the bottom of the outer tube 13 upwards through the pulley 88 so that the outer tube 13 moves upwards relative to the middle tube 12, further, as the outer tube 13 moves upwards, the lower nest pull wire 81 pulls the lower nest 22 upwards through the pulley 87 so that the umbrella ribs 10 are opened, and the electronic control assembly 42 automatically controls to stop releasing electric energy to the rotating power assembly 41, and the umbrella is in the umbrella opening state as shown in fig. 1.
When the umbrella is to be folded, the button 31 on the umbrella handle 3 is pressed again to press the electronic control assembly 42 to release electric energy to drive the rotating power assembly 41 to rotate the transmission slide shaft 5 in the forward direction, the transmission slide shaft 5 drives the bidirectional screw rod 6 to rotate in the forward direction, so that the upper sleeve 71 and the lower sleeve 72 move synchronously in the direction close to the middle part of the bidirectional screw rod 6, the inner pipe 11 is driven to move upwards relative to the bidirectional screw rod 6, the middle pipe 12 moves downwards relative to the bidirectional screw rod 6, and as a result, the middle pipe 12 moves downwards relative to the inner pipe 11 by a distance twice of the displacement of the bidirectional screw rod 6 and is folded and sleeved outside the inner pipe 11. In the process, as the distance between the top of the bidirectional spinning rod 6 and the top of the middle tube 23 is shortened, the outer tube 13 loses the pulling force of the outer tube pulling wire 82 and moves downwards under the action of gravity to be sleeved outside the middle tube 12, further, the lower nest 22 loses the pulling force of the lower nest pulling wire 81 and moves downwards under the action of the furling force and the gravity of the umbrella ribs 10, further, the upper sleeve 71 is pulled upwards through the lower nest pulling wire 81 to further accelerate the folding and sleeving between the outer tube 13 and the middle tube 12, as one end of the outer tube pulling wire 82 is fixed on the first pulley seat 83 and the other end is fixed on the bidirectional spinning rod 6 to form mutual pulling force traction, the pipe fittings of the middle rod 1 cannot be stretched, the electronic control component 42 automatically controls to stop releasing electric energy to the rotating power component 41, and the umbrella is in the umbrella folding state as shown in fig. 4.

As shown in fig. 9, a third pulley seat 85 is fixedly disposed on the top of the outer tube 13, and a pulley 86 is mounted on the third pulley seat 85. One end of the lower nest stay wire 81 is fixedly connected to a slotted hole formed in the top of the bidirectional rotary screw rod 6, and the other end of the lower nest stay wire is sequentially wound around a pulley 86 arranged at the third pulley seat 85 and a pulley 87 arranged at the lower nest 22 and then is upwards connected to the third pulley seat 85. In the second embodiment, the third pulley seat 85 is fixedly connected to the top of the upper sleeve 71.
In addition, a compression spring 9 is further installed in the outer tube 13, the top of the compression spring 9 abuts against the third pulley seat 85, and the bottom of the compression spring 9 abuts against the middle tube 12, so that the middle tube 12 can be prevented from retracting into the outer tube 13 when the umbrella is opened.
As shown in fig. 8 and 9, when the umbrella is to be opened, the upper sleeve 71 and the lower sleeve 72 respectively drive the outer tube 13 and the inner tube 11 to move synchronously in a direction away from the middle of the bidirectional screw rod 6, so as to extend the outer tube 13, the middle tube 12 and the inner tube 11, the compression spring 9 can assist the extension between the middle tube 12 and the outer tube 13, in the process, the upper sleeve 71 and the outer tube 13 move upwards relative to the bidirectional screw rod 6, the lower nest pull wire 81 is pulled to pull the lower nest 22 upwards through the pulley 87, so that the umbrella ribs 10 are opened, until the umbrella is in the opened state shown in fig. 8, and the electronic control assembly 42 automatically controls to stop releasing electric energy to the rotating power assembly 41.
When the umbrella is to be folded, the upper sleeve 71 and the lower sleeve 72 respectively drive the outer tube 13 and the inner tube 11 to synchronously move towards the direction close to the middle part of the bidirectional screw rod 6, so that the outer tube 13, the middle tube 12 and the inner tube 11 are compressed and sleeved together, at this time, the upper sleeve 71 and the outer tube 13 move downwards relative to the bidirectional screw rod 6, the lower nest 22 also loses the pulling force of the lower nest pulling wire 81 and moves downwards under the action of the furling force and gravity of the umbrella ribs 10, and as one end of the lower nest pulling wire 81 is fixed on the third pulley seat 85 and the other end is fixed on the bidirectional screw rod 6 to form mutual pulling force traction, the pipe fittings of the middle rod 1 cannot be stretched, the electronic control assembly 42 automatically controls to stop releasing electric energy to the rotating power assembly 41, and at this time, the umbrella is in the umbrella folding state as.
