In the present embodiment, the axial hole 133 has a circular cross section, and the diameter of the axial hole 133 is 6mm or more and 15mm or less. For example, the axial bore 133 may have a diameter of 6mm, 10mm, or 15 mm.

The shape of the radial holes 134 may be polygonal, circular, elliptical, or other combinations. The radial hole 134 may be formed in the support plate 150, and may be formed by partially hollowing out the support plate 150. The supporting plate 150 can be fixedly connected with the upper housing 210 or the upper baking tray 220 by means of integral molding, welding, screwing or clipping.

In the present embodiment, the upper grill pan assembly 200 and the lower grill pan assembly 300 are wired through the wiring channel of the hinge shaft 130 to achieve electrical connection; the hinge shaft 130 is hinged with the positioning seat 350; ratchet tooth 131 of articulated shaft 130 and prevent changeing stopper 351 spacing cooperation, prevent changeing stopper 351 be used for with 130 unilateral rotation of articulated shaft when with ratchet tooth 131 butt cooperation in order to restrict articulated shaft 130 in the ascending rotational position of unilateral. That is, the frying and roasting machine 10 and the hinge shaft provided in this embodiment can perform hidden wiring, hinge and positioning functions.

The toaster 10 may further include a top block 140, a cam shaft 120, and a cam 110. The cam 110 includes a rotation center 111 and an outer circumferential surface 112, and the outer circumferential surface 112 is provided with a plurality of stopper portions 113 so that the cam 110 forms a plurality of predetermined support heights. The cam shaft 120 is used for arranging the cam 110 so that the cam 110 is fixed on the cam shaft 120, and the cam shaft 120 is assembled and connected with the lower roasting plate assembly 300 so that the cam shaft 120 can be rotatably arranged in the lower housing 310. The top block 140 is disposed between the cam 110 and the hinge shaft 130 to transmit the pushing force of the cam 110, a supporting portion 142 for supporting the hinge shaft 130 is disposed at an end of the top block 140 away from the cam 110 to support the hinge shaft 130, and the supporting portion 142 is a groove or a through hole, so that the hinge shaft 130 can rotate in the groove or the through hole.

The frying and roasting machine 10 may further include a control device (not shown) for controlling the temperature of an upper heating tube (not shown) of the upper roasting tray assembly 200 and the temperature of an upper heating tube (not shown) and a lower heating tube (not shown) of the lower roasting tray assembly 300, wherein the upper heating tube is connected to the control device through a first wire, and the first wire may pass through a wire path in the hinge shaft 130; the lower heat-generating pipe is connected with the control device through a second wire, and the second wire can pass through the wiring channel in the hinge shaft 130.

Be different from prior art's condition, the utility model provides an among articulated shaft and the machine of baking by frying in shallow oil of using it, because the articulated shaft is equipped with to walk the line passageway and pass and then the electricity is connected roast dish subassembly and lower overware subassembly in order to allow the wire, consequently can make the wire in the machine of baking by frying in shallow oil pass and walk the line passageway, the protection wire does not receive the damage.
