As shown in fig. 4 and 5, the driving unit 22 includes a bracket 221, a transmission shaft 222, a first gear 223, a second gear 224, a fixing seat 225 and a driving shaft 226. The bracket 221 has one end pivotally connected to the left pivot point p4 of the middle transverse link 21b, and the other end bent upward and located a predetermined distance d above the first longitudinal link 21d to accommodate the first gear 223. The shaft 222 has a transmission portion 227 and a pivot portion 228 (see fig. 10), the transmission portion 227 is located above the pivot portion 228, the cross section of the transmission portion 227 is regular hexagon, and the cross section of the pivot portion 228 is circular. The first longitudinal link 21d is provided with a hexagonal hole at a position corresponding to the left pivot point p1 of the pivot left transverse link 21a, and the transmission portion 227 of the transmission shaft 222 is coaxially fixed to the first gear 223 and is engaged with the hexagonal hole of the first longitudinal link 21 d.

It should be noted that, as shown in fig. 3, in order to enhance the structural stability of the snow shoveling apparatus 1, a set of pivot mechanisms 30 is further disposed at the bottom side of the snow shoveling plate assembly 10, such that the pivot mechanisms 30 can connect the snow shoveling plate units 11a-11 c. The hinge mechanism 30 includes a left connecting rod 31, a middle connecting rod 32, a right connecting rod 33, a first hinge rod 34 and a second hinge rod 35. The left connecting rod 31 is connected to the bottom side of the left snowboard unit 11a, the middle connecting rod 32 is connected to the bottom side of the middle snowboard unit 11b, and the right connecting rod 33 is connected to the bottom side of the right snowboard unit 11 c. The first pivoting lever 34 has one end pivotally connected to the right end of the left connecting rod 31 and the other end pivotally connected to the middle of the middle connecting rod 32, and the second pivoting lever 35 has one end pivotally connected to the right end of the middle connecting rod 32 and the other end pivotally connected to the right end of the right connecting rod 33.

In practice, when a user needs to use the snow shoveling device 1 of the embodiment to shovel snow, the user can rotate the driving shaft 226 of the link mechanism 20 by using an electric screwdriver (provided with a hexagonal socket, not shown), so that the snow shoveling plate assembly 10 is driven by the link mechanism 20 to be converted into the unfolded state (as shown in fig. 1), and the snow shoveling plate units 11a-11c are transversely arranged, so that the front sides 12 jointly form a snow shoveling surface to shovel snow. When the user wants to store the snow shoveling device 1 without shoveling snow, the user can use the electric screwdriver to rotate the driving shaft 226 of the link mechanism 20 in the reverse direction to convert the snow shoveling plate assembly 10 into the folded state (as shown in fig. 5), and at this time, the snow shoveling plate units 11a-11c are arranged obliquely and longitudinally, thereby reducing the width of the snow shoveling plate assembly 10 in the transverse direction and facilitating the user to store the whole snow shoveling device 1.

In order to more effectively secure the blade units 11a-11c when the blade assembly 10 is in the extended position, two locking assemblies 40 are also used in this embodiment. Referring to fig. 6 to 8, the two locking assemblies 40 are respectively disposed between the left snowboard shoveling plate unit 11a and the middle snowboard shoveling plate unit 11b and between the middle snowboard shoveling plate unit 11b and the right snowboard shoveling plate unit 11 c. Each locking assembly 40 structurally includes a socket 41, a pin 42, a positioning unit 43 (see fig. 8) and a mounting seat 44, taking the locking assembly 40 disposed between the middle shovel unit 11b and the right shovel unit 11c as an example (the locking assemblies 40 of the left shovel unit 11a and the middle shovel unit 11b can be analogized in this way), the socket 41 is disposed on the middle shovel unit 11b, the mounting seat 44 is disposed on the right shovel unit 11c, the pin 42 is movably disposed in the mounting seat 44, the pin 42 is structurally elongated and has a first positioning hole 421 and a second positioning hole 422, and a flange 423 is further disposed at the right end of the pin 42 to facilitate the user to stack the pin 42. Referring to fig. 8, the positioning unit 43 includes a positioning pin 431 and a compression spring 432, the positioning pin 431 has a plugging portion 433 and a stopping portion 434, and two opposite sides of the compression spring 432 respectively abut against between the inner wall of the mounting seat 44 and the stopping portion 434. When the plug pin 42 is pushed to an unlocking position (as shown in fig. 6), the plug pin 42 is not inserted into the socket 41, and the insertion portion 433 of the positioning pin 431 is inserted into the second positioning hole 422 of the plug pin 42. When the user wants to lock the middle shovel board unit 11b and the right shovel board unit 11c, the user can pull the positioning pin 431, so that the stopping portion 434 of the positioning pin 431 compresses the compression spring 432, the compression spring 432 accumulates an elastic restoring force, and the inserting portion 433 is separated from the second positioning hole 422, so that the user can push the pin 42 through the flange 423 to insert the tail end of the pin 42 into the socket 41 (as shown in fig. 7), thereby locking the middle shovel board unit 11b and the right shovel board unit 11c, at this time, the user can put down the positioning pin 431, push the stopping portion 434 of the positioning pin 431 through the elastic restoring force of the compression spring 432, so that the inserting portion 433 of the positioning pin 431 is inserted into the first positioning hole 421, and thus, the positioning of the pin 42 can be completed.
