[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 An embodiment of the utility model discloses a lever device for crimping a positive nickel strip, the lever device comprising a frame 1, two oppositely arranged supports 2 are fixed above the frame 1, a guide member 3 is fixedly installed between the two supports 2, and a sliding member 4 is slidably connected to the outer side of the guide member 3;

[0023] In some embodiments, the guide member 3 in the utility model is a guide rod arranged between the two supports 2, and the two ends of the guide rod respectively pass through the two supports 2 and are locked at their ends by locking members 31. Specifically, the locking members 31 described in this embodiment are configured as nuts, that is, both ends of the guide rod in this embodiment are provided with threaded sections. After the two ends of the guide rod pass through the two supports 2, the ends of the guide rod can be locked and fixed by nuts to achieve assembly and fixation of the guide rod.

[0024] Further, such as Figure 1 As shown, in this embodiment, a side wing 41 is fixed to the bottom of the sliding member 4, the lever 5 and the side wing 41 rotate via a first shaft 42, and the rolling member 7 and the lever 5 rotate via a second shaft 71.

[0025] Specifically, in the present embodiment, the first shaft 42 and the second shaft 71 are both configured as T-shaped pins, and the locking of the plug-in position is achieved through the T-shaped ends thereof. An annular groove is provided at the end of the T-shaped pin, and a retaining spring 8 is clamped in the annular groove. That is, in the present embodiment, the retaining spring 8 is used to connect the first shaft 42 and the second shaft 71, so that the detachable function of the lever 5 and the rolling member 7 can be achieved.

[0026] In some embodiments, Figure 2 As shown, a fixing seat 9 is fixedly installed at the end of the driving member 6 in the utility model, and the fixing seat 9 is fixedly connected to the end of the lever 5 by a fastener. Preferably, the fastener described in this embodiment is configured as a bolt, that is, the fixing seat 9 is fixed to the end of the lever 5 by a bolt to achieve a detachable connection to the driving member 6, thereby improving the convenience of installation and replacement of the driving member 6.

[0027] Further, such as Figure 3 As shown, the driving member 6 in this embodiment includes a first rod member 61 and a second rod member 62, and a length adjustment structure is provided between the first rod member 61 and the second rod member 62, that is, in this embodiment, the length of the lever arm can be changed by adjusting the length of the first rod member 61 and the second rod member 62.
