A planar controllable slippage type wood forklift with a multi-unit connection rod driving function comprises a multi-unit connection rod driving mechanism, a movable arm lifting mechanism, a fork bucket control mechanism and the like. Under control of a computer, the multi-unit connection rod driving mechanism achieves driving of multiple small-power motors and high-power and high-torque power output, and meets the power requirement of high-load operation of the slippage type wood forklift. A hydraulic cylinder is applied to the configuration design of the wood forklift as a connection rod on the basis of the Pascal principle, the problem that in the prior art, stress on two driving chains for lifting a movable arm is unbalanced is effectively solved, and the bearing stability is improved. The slippage type wood forklift not only has the characteristics of being high in transmission efficiency, high in response speed, high in motion precision, good in controllability, capable of saving energy, environmentally friendly and the like as a controllable mechanism, but also has better bearing performance and shock resistance through introduction of the multi-unit connection rod driving mechanism and a hydraulic element, can achieve the overload protection function easily and has great engineering application prospects and development potential.

The invention discloses a high-performance wave spring. The wave spring comprises a circular spring body; the spring body adopts an open loop structural design, and is alternatively provided with crest and trough structures with the same specifications; and the outer edges of the crest and trough structures are plane structures. The high-performance wave spring, provided by the invention, is reasonable in structural design, simple in preparation process and proper in cost; the outer edges of the crest and the trough structures on the spring body adopt the plane structures; and the structures can effectively improve the stability of the wave spring in the mounting and use process, so that the nonuniform stress phenomenon is improved, and the service life of the wave spring is prolonged to a certain extent.

The invention discloses a nail guiding structure, comprising a guiding plate, at least one supporting member and a pushing and butting means. The guiding plate is vertically arranged in front of a nail rail and is provided with a first face and a second face, the first face of the guiding plate faces to the nail rail, the guiding plate is provided with at least one vertical penetration groove which penetrates through the first face and the second face of the guiding plate, the supporting member penetrates into the penetration groove in a manner of sliding back and forth, the supporting member is provided with a supporting end and a pushing and butting end, the supporting end selectively protrudes and extends outside the first face, the pushing and butting end is located at the side with the second face, the supporting member is further provided with at least one supporting face which is parallel to the extending direction of the nail rail and is used for supporting and righting a nail pin, and the pushing and butting means is used for elastically pushing and butting the pushing and butting end, and thus, the supporting end is endowed with a trend of protruding and extending to the outside of the first face.

The invention discloses a steering pull rod swinging arm comprising a swinging arm body, a skeleton and a sliding bearing. The swinging arm body and the skeleton are subjected to insert injection molding; the skeleton comprises a skeleton main body, a sliding bearing seat, a first steering pull rod lining and a second steering pull rod lining; the gravity center of a triangle constituted by geometric centers of a sliding bearing seat notch, a first steering pull rod lining notch and a second steering pull rod lining notch coincides with the gravity center of the skeleton; and the sliding bearing is fixed into the sliding bearing seat in an embedded mode. According to the steering pull rod swinging arm, the swinging arm body is formed on the skeleton through an insert injection molding technology, and the cost is low; and through all the notches in the skeleton main body, the problem of uneven force bearing of the steering pull rod swinging arm is solved advantageously, and thus the service life of the steering pull rod swinging arm is prolonged.

The present invention provides a transfer device for a micro device, comprising: a first base; a transfer base, the transfer base is formed on the first base, and the transfer base is used to carry a plurality of micro devices; the first base At least one cushioning element is also included between the transfer substrate and the transfer substrate. The transfer device of the micro device of the present invention can provide a buffer force when transferring the micro device, so as to prevent the micro device from being damaged.
