Please refer to Figure 1. Figure 1 provides an embodiment of the present invention. The opener includes an outer cylinder 1 and a first inner cylinder 2. The first inner cylinder 2 is provided in the outer cylinder 1 and can be moved along a predetermined direction in the outer cylinder 1. Assuming the direction of movement, a hook 4 is hinged on the wall of one end of the outer cylinder 1. The hook head of the hook 4 is exposed from the outer cylinder 1. There are at least two hook heads 4 arranged opposite to each other and can be passed around the hinge point. The rotation of the hook increases the distance between the two hook heads, and also includes a device that can drive the hook 4 to rotate by acting on one end of the hook 4 located in the outer cylinder 1 as the first inner cylinder 2 moves in the preset direction. Driving mechanism, the beneficial effect of this embodiment is that two hooks 4 are provided at the end of the outer cylinder. The hook heads of the two hooks 4 are arranged oppositely, and the two are on the same straight line. When using, first The two hooks 4 are inserted into the hole 16 of the lead seal that needs to be opened. The hole 16 is shown in Figure 2. After insertion, the first inner cylinder 2 is moved in the outer cylinder 1, and the driving mechanism will act on the hooks 4. , causing the two hooks 4 to rotate, so that the hook heads of the two hooks 4 move far away respectively. If the distance is increased, the lead seal will be stuck, and then the outer cylinder 1 is lifted, and the lead seal can be pulled out smoothly. That is to say, the technical solution provided by this embodiment can open the lead seal conveniently and quickly without using a traditional screwdriver to pry, which greatly facilitates the opening process and speeds up work efficiency.

Furthermore, the hook 4 is L-shaped, and the L-shaped hook 4 is the best choice. The effect is that the hook head part of the L-shaped hook 4 is perpendicular to the hook body part, and it is easy to push to both sides when rotating, and The hook body part is linear and is easy to cooperate with the driving mechanism. The driving mechanism can more conveniently realize the rotation of the hook 4 by driving the linear part of the hook body.

Further, as shown in Figure 1, an embodiment of the driving mechanism is provided. The driving mechanism includes a roller 5 provided at the end of the first inner cylinder 2, and an inclined surface 6 provided at the inner end of the outer cylinder 1 of the hook 4. The roller 5. The traveling route is a straight line, and the roller 5 pushes up the inclined surface 6 during the movement to realize the rotation of the hook 4. When the first inner cylinder 2 moves downward, the roller 5 will touch the inclined surface 6. Since the track of the roller 5 is a straight line, the hook 4 will rotate under the action of the pushing inclined surface 6, so that the hook head moves to both sides. movement, stuck in the strip hole 16 of the lead seal as shown in Figure 2. This embodiment adopts a simple pushing form in which the roller 5 interacts with the slope 6 to realize the rotation of the hook 4, so the structure is simple and the operation is convenient. The biggest advantage of this embodiment.

Based on the embodiment shown in Figure 1, a further technical feature is that the outer wall of the first inner cylinder 2 does not contact the inner wall of the outer cylinder 1. The purpose of the non-contact is to better make the first inner cylinder 2 move along the The length direction of the outer cylinder 1 slides to reduce friction, so that the movement of the first inner cylinder 2 can be realized without a large force, and the purpose of simple and convenient operation is also achieved.

Further, as shown in Figure 1, a second inner cylinder 2 is also provided in the outer cylinder 1. The first inner cylinder 2 is also connected to a coaxial guide rod 7. The center hole of the second inner cylinder 2 The diameter is equal to the diameter of the guide rod 7. The guide rod 7 is inserted into the central hole of the second inner cylinder 2 and is slidably arranged. This technical feature provides a mechanism for the first inner cylinder 2 to move along the direction of the outer cylinder 1. The structural form uses the guide rod 7 as a guiding function, which greatly realizes the accuracy of the movement of the first inner cylinder 2. Due to the guide rod 7, no matter the contact between the cylinder wall of the first inner cylinder 2 and the inner wall of the outer cylinder 1, No, it can move accurately to achieve accurate positioning and contact between the roller 5 and the inclined surface 6.

Further, as shown in Figure 1, an example of how the first inner cylinder 2 realizes movement is given. A fixed plate 9 and a moving plate 8 are provided on the wall of the outer cylinder 1, and the moving plate 8 passes through the outer cylinder. 1. The wall of the cylinder is connected to the outer wall of the first inner cylinder 2. The wall of the outer cylinder 1 is provided with a long slot parallel to the moving direction of the first inner cylinder 2. The moving plate 8 is located in the long slot. The moving plate 8 and the fixed plate A first bolt 12 is passed between the moving plate 8 and the fixed plate 9, and a matching nut is provided on the first bolt 12. A first spring 10 is passed through the part of the first bolt 12 between the moving plate 8 and the fixed plate 9. When movement is required, By twisting the nut, the movement of the movable plate 8 can be realized under its pushing action, thereby realizing the movement of the first inner cylinder 2. The first spring 10 is used to realize the reset of the movable plate 8 when the nut is unscrewed. This embodiment The beneficial effect is that by manually adjusting the nut to realize the movement of the first inner cylinder 2, the movement can be turned into a slow and progressive movement without instantaneous movement, damage to the driving mechanism or hook, and no hard collision. And the action force can be fine-tuned through the nut, and the hook head has a reasonable clamping force.

Further, as shown in Figure 1, the second inner cylinder 3 is fixedly arranged, and the second inner cylinder 3 is also provided with a handle extending outside the outer cylinder 1. The beneficial effect of this technical feature is that by controlling the handle, it can Effectively operate the height of the outer cylinder 1 to facilitate lifting the outer cylinder 1 so that the hook 4 hooks the lead seal and then pulls out the lead seal.

Further, as shown in Figure 1, the second inner cylinder 3 is fixed by a second bolt 13 passing through the wall of the outer cylinder 1. The outer diameter of the second inner cylinder 3 is smaller than the inner diameter of the outer cylinder 1. The inner wall of the outer cylinder 1 is provided with a raised portion 15, and the raised portion 15 has a hole. The second inner cylinder 3 passes through the hole of the raised portion 15, and the second bolt 13 passes through it. The raised portion 15 then contacts the second inner cylinder 3 , and the raised portion 15 is provided with threads that match the second bolt 13 . A second spring 13 is connected between the two hooks 4 with opposite hook heads. The second spring 13 is connected to one end of the hook 4 located inside the outer cylinder 1 . The function of the second spring 13 is to provide rebound force.

To sum up, compared with ordinary screwdrivers, this opener is more convenient, simpler and faster to use, has a simple structure and is easy to operate, which greatly improves work efficiency.
