The telescopic universal joint 33 has at least two universal joints, and the telescopic structure can be arranged at any section. If the coupler with more than three universal joints is adopted, the universal joint coupler has certain telescopic capacity, and each section of the coupler can have no telescopic structure.

The design is described by taking only two universal joints and a three-section type coupling as an example, and the middle section of the telescopic structure is taken as an example. The wood board is a cuboid wood board which is only unprocessed, the pencil board is a whole formed by clamping a pencil lead between two wood boards after grooving, pressurizing and drying, and the wood board is also of a cuboid structure.

Based on the scheme, the normal working process is as follows, a wood board or a pencil board moves from the feeding side of the rack 1 to the propelling wheel 22, the driving source directly or indirectly drives the driving shaft 32 to rotate, the driving shaft 32 drives the telescopic universal coupling 33 to rotate, so that the propelling wheel shaft 21 connected with the telescopic universal coupling 33 is driven to rotate, all the propelling wheel shafts 21 are driven to rotate in the same direction, all the propelling wheels 22 rotate in the same direction at the moment, and the wood board or the pencil board conveyed to the lower side of the propelling wheel 22 is conveyed to the processing equipment (a router or a planer).

When the specifications of the pencil to be processed are changed, the thicknesses of the wood board and the pencil board are changed, so that the distance between the propelling wheel 22 and the lead base plate 11 needs to be adjusted.

The adjusting process comprises the following steps of obtaining a reasonable distance between the propelling wheel 22 and the wire bottom plate 11 through measurement or previous data, loosening the positioning assembly 4 to enable the propelling wheel adjusting block 2 to freely lift, moving the propelling wheel adjusting block 2 to a required height according to the reasonable distance (when the propelling wheel adjusting block 2 lifts, the propelling wheel 22 and the propelling wheel shaft 21 lift simultaneously), locking the positioning assembly 4 to limit the minimum height of the propelling wheel adjusting block 2, and completing adjustment. In the adjusting process, one end of the telescopic universal coupling 33, which is connected with the propelling wheel shaft 21, vertically ascends or descends and keeps parallel to the wire bottom plate 11; the telescopic universal coupling 33 and the driving shaft 32 are connected at one end to keep the position unchanged, the middle section is telescopic, and the front and rear driving sources can be adjusted to always drive the propelling wheel 22 to rotate. In the design and adjustment process, only the height position of the propelling wheel adjusting block 2 needs to be adjusted, the height of the bearing seat 31 does not need to be adjusted, moving parts are few during adjustment, the adjustment is convenient, the speed is high, and the efficiency is high.

Specifically, the propulsion wheel shaft 21 is provided with a propulsion wheel gear 211, and the propulsion wheel gear 211 is connected with a propulsion wheel gear 211 on another propulsion wheel shaft 21 through a chain 212.
