[0005] Further preferably, a layer of MC cast nylon is fixed to opposite sides of the two clamp arms.

[0006] Further preferably, arc grooves are provided on opposite sides of the two clamp arms, and the MC cast nylon is designed as an arc structure and embedded in the arc grooves and fixed to the clamp arms by screws.

[0007] Further preferably, the telescopic drive assembly is one of a pneumatic cylinder, a hydraulic cylinder or an electric cylinder.

[0008] Further preferably, a slot is provided downwardly at the top of each of the two clamp arms, and the two clamp arms are cross-arranged through the slot.

[0009] The utility model achieves the following beneficial effects:

[0010] Two sets of stick clamps of the present application can automatically clamp the left and right ends of the stick. When used in conjunction with the crane hoist hook, the stick can be suspended. Compared with the stick fixing method in the prior art, the degree of automation is higher, the clamping time of the stick is reduced, and work efficiency is improved.

[0016] 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.

[0017] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0018] Example

[0019] refer to Figure 1-Figure 3 As shown, the present application discloses a stick clamp for slitting and winding lithium battery diaphragms, comprising a base 10, a telescopic drive assembly 20, two connecting rods 30 and two clamp arms 40. A bearing seat 50 is arranged below the base 10. The top ends of the two connecting rods 30 are connected to the inner ring of the bearing of the bearing seat 50 through a first hinge shaft 60. The two clamp arms 40 are cross-hinged at the bottom of the two connecting rods 30 through second hinge shafts 70 respectively. The intersection centers of the two clamp arms 40 are connected through a third hinge shaft 80. The telescopic drive assembly 20 is connected and arranged between the two second hinge shafts 70. Under the drive of the telescopic drive assembly 20, the two clamp arms 40 perform opening and closing actions.

[0020] In addition to the above features, a layer of MC cast nylon 90 is fixed on the opposite side of the two clamp arms 40 of the present application. Since MC cast nylon 90 has multiple unique properties such as light weight, high strength, self-lubrication, wear resistance, corrosion resistance, insulation, etc., the use effect of the clamp arm 40 of the present application is increased.

[0021] As for the installation method of the MC cast nylon 90, an arc groove 41 is opened on the opposite side of the two clamp arms 40 of the present application. The MC cast nylon 90 is designed as an arc structure and is embedded in the arc groove 41 and fixed to the clamp arm 40 by screws.

[0022] It can be selected that the telescopic drive component 20 is one of a pneumatic cylinder, a hydraulic cylinder or an electric cylinder. In specific use, if other types of telescopic drive components 20 can achieve the relevant functions of the present application, this technical field can also be adaptively selected.

[0023] In order to better install the two clamp arms 40, the present application provides a slot 42 downward from the top of the two clamp arms 40, and the two clamp arms are cross-arranged through the slot 42. In addition to the above effects, when the two telescopic clamp arms 40 are used to clamp the stick 100, it can play a stabilizing role.
