[0031] The base 1 forms a chamber, and a compression locking structure is arranged in the chamber; the compression locking structure comprises a fixed seat 6, and connecting plates 7 are arranged on both sides of the fixed seat 6. The lower ends of the connecting plates 7 are rotatably connected to the fixed seat 6, so that the connecting plates 7 can swing relative to the fixed seat 6. A rotating rod 8 is rotatably arranged between the upper ends of the connecting plates 7 on both sides, and the rotating rod 8 is connected to the handle 3. Figure 1 The handle 3 is inserted into the mounting hole and connected to the rotating rod 8, that is, the connection part of the handle 3 and the rotating rod 8 is hidden in the interior of the upper shell 2, which is helpful to improve the appearance and safety; the rotating rod 8 is provided in a flat shape, and the handle 3 is provided with a flat assembly groove matching the shape of the rotating rod 8, so that the handle 3 is matched and installed with the rotating rod 8 and then locked; compared with the design of the rotating rod 8 in a circular shape, the flat shape can enhance the linkage of the handle 3 and the rotating rod 8, that is, the handle 3 and the rotating rod 8 are not easy to slip, so that the swinging handle 3 can well control the rotation of the rotating rod 8.

[0032] The fixed seat 6 is connected to the base 1, and the handle 3 is connected to the upper shell 2, so that pulling the handle 3 can control the upper shell 2 to swing up and down, that is, control the upper pressing plate 5 to open and close relative to the lower pressing plate 4. The rotating rod 8 is further provided with a tension cam 9, the tension cam 9 is connected with one end of a pull rod 10, the other end of the pull rod 10 is connected with a cam arm 11; further comprising a connecting shaft 12, both ends of the connecting shaft 12 are connected to the connecting plates 7, the middle part of the cam arm 11 is rotatably connected to the connecting shaft 12; the lower end of the cam arm 11 is connected with a elastic tension member 13.

[0033] As Figure 5As shown, the elastic tension component 13 comprises an outer cylinder 1301, an inner rod 1302 and a bearing seat 1303, the inner rod 1302 is slidingly connected in the outer cylinder 1301; the cam arm 11 has a lower end surface 1101, the outer cylinder 1301 is connected with the lower end surface 1101; the bearing seat 1303 has an upper end surface 13031, the inner rod 1302 is connected with the upper end surface 13031; the outer cylinder 1301 is externally sleeved with a spring 1304, the upper end of the spring 1304 abuts against the lower end surface 1101 of the cam arm 11, and the upper end of the spring 1304 abuts against the upper end surface 13031 of the bearing seat 1303; therefore, the inner rod 1302 can be pulled out in the outer cylinder 1301, and the spring 1304 can reset the position between the inner rod 1302 and the outer cylinder 1301.

[0034] The fixed seat 6 is provided with a track groove 14 corresponding to the elastic tension component 13, the lower end of the elastic tension component 13 slidingly abuts against the track groove 14; the two sides of the bearing seat 1303 are provided with bearings 1305, the bearings 1305 are rollingly connected on the track groove 14, so that the lower end of the elastic tension component 13 (the bearing seat 1303) can be connected on the track groove 14 in a rolling manner, the friction is small, and the movement is smooth.

[0035] And the track groove 14 is in a curved shape extending upwards, and the higher it is, the closer it is to the connecting shaft 12; the rotation of the cam arm 11 drives the elastic tension component 13 to move along the track groove 14, so that the pressing force of the elastic tension component 13 on the cam arm 11 gradually increases or gradually decreases. Figure 6 And Figure 7 As can be seen, the track groove 14 is in a curved parabolic arc shape, the lowest point A where the lower end of the elastic tension component 13 (the bearing 1305 on the bearing seat 1303) contacts on the track groove 14 is set, and the highest point B where the lower end of the elastic tension component 13 (the bearing 1305 on the bearing seat 1303) contacts on the track groove 14 is set, since the track groove 14 is curvedly closer to the connecting shaft 12 the higher it is, therefore, when the lower end of the elastic tension component 13 moves from the point A to the point B, the spring 1304 is in a gradually compressed state, and the pressing force of the spring 1304 on the cam arm 11 gradually increases; when the lower end of the elastic tension component 13 moves from the point B to the point A, the spring 1304 is in a gradually recovered elongation state, and the pressing force of the spring 1304 on the cam arm 11 gradually decreases.

[0036] The inner rod 1302 is provided with a convex edge 13021 in the length direction, and the inner part of the outer cylinder 1301 is correspondingly provided with a groove 13011, and the convex edge 13021 is slidingly assembled in the groove 13011. The convex edge 13021 and the groove 13011 are arranged so that the inner rod 1302 does not rotate in the radial direction when sliding in the outer cylinder 1301, that is, at least to ensure that the bearing seat 1303 does not twist, so that the bearing 1305 stably slides along the track groove 14.

[0037] The handle 3 is integrally formed in a ring-shaped closed shape. Multiple parts of the handle 3 can be operated to facilitate convenient use.

[0038] The working principle of the electric iron is as follows: first, pull down the handle 3 to drive the upper shell 2 to swing, so that the upper pressing plate 5 of the upper shell 2 presses on the lower pressing plate 4 of the base 1 to iron the clothes; then turn the handle 3 downward to drive the rotating rod 8 and the tension cam 9 to rotate, thereby pulling the pull rod 10 forward to swing the cam arm 11 forward, and finally driving the elastic tension component 13 to rotate from the Figure 6 state to the Figure 7 state. As described above, the spring 1304 is in a compressed state at this time, thereby resisting the cam arm 11, which complies with the principle of the lever triangle to lock the handle 3, and the operator will not turn the handle 3 back, avoiding fatigue. When the ironing time is enough, turn the handle 3 upward to drive the rotating rod 8 and the tension cam 9 to rotate, thereby pushing the pull rod 10 backward, and finally driving the elastic tension component 13 to rotate from the Figure 7 state to the Figure 6 state, that is, no longer resisting the cam arm 11, and then lifting the handle 3 upward to drive the upper shell 2 to turn upward, that is, to separate the upper pressing plate 5 from the lower pressing plate 4, so that the clothes can be taken away.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent replacements to some technical features, but any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
