(11) That is, when the slide rail is assembled, the guide snap 4 and the front holder 3 are slidably mounted on the transverse rod 11 of the connecting frame 1 in order. When the guide snap 4 and the front holder 3 slip to the corner positions at the two ends of the transverse rod 11, there is only a need to lock the latch rod 6 onto the front holder 3, to make the guide snap 4 and the front holder 3 be held at the two ends of the transverse rod 11 respectively, so the mechanism has a locking function while achieving the effect of quickly assembling the slide rail on an oven liner, has a good holding effect, preventing the slide rail from being disengaged from the connecting frame 1, improving the reliability of structural performance, ensuring the use effect of the slide rail, guaranteeing the use quality of an oven. When the slide rail is disassembled, there is only a need to toggle the latch rod 6, to disengage the latch rod 6 from the front holder 3, so as to make the front holder 3 and the guide snap 4 slide off the transverse rod 11 in sequence. Thus the slide rail is quickly disassembled, facilitating replacement and maintenance, improving the use quality of the slide rail, guaranteeing the use effect of an oven.

(12) As shown in FIG. 1-FIG. 6, the front holder 3 comprises a U-shaped holding block slipping in the same horizontal direction as the guide snap 4. An upper end of the U-shaped holding block is provided with a latch fastener slot 31, and a low end of the U-shaped holding block is provided with an open fastener slot 32 and a connecting fastener position 33. The latch rod 6 is provided with a toggle latch block 61, an inner-side limiting fastener block 62 and a corner limiting fastener block 63. The toggle latch block 61 is adaptively fastened or separated in the latch fastener slot 31, and the inner-side limiting fastener block 62 and the corner limiting fastener block 63 are fastened or separated in the open fastener slot 32 and the connecting fastener position 33 respectively under the driving of the toggle latch block 61.

(13) In practical application, a positioning end of the latch rod 6 is connected to a rear end of the front holder 3 in a positioning mode, and a swing end of the latch rod 6 is swung up and down by taking the positioning end thereof as a fixed point. Moreover, the swing end of the latch rod 6 is outward folded to form the inner-side limiting fastener block 62, the corner limiting fastener block 63 and the toggle latch block 61 respectively. Holding positions held at a straight bar part of the transverse rod 11 and the corner position are formed by the inner-side limiting fastener block 62 and the corner limiting fastener block 63 which are fastened in the open fastener slot 32 and the connecting fastener position 33 and the U-shaped guide groove 34.

(14) When the guide snap 4 and the front holder 3 slip to the corner positions at the two ends of the transverse rod 11, the toggle latch block 61 of the latch rod 6 is toggled, to make the toggle latch block 61 be fastened in the latch fastener slot 31. Meanwhile, the inner-side limiting fastener block 62 and the corner limiting fastener block 63 are fastened in the open fastener slot 32 and the connecting fastener position 33 respectively under the driving of the toggle latch block 61.
