The cross member is accommodated in the slide groove 121 and slides in the slide groove 121 in the axial direction of the knob body 10.
The crossbeam both ends that adopt above-mentioned structure all link to each other with side coaming 21, and structural strength and reliability are higher to this regard as spacing portion 23, on the one hand, can promote spacing portion 23's intensity and stability, prevent that spacing portion 23 from damaging the normal operating that influences sleeve 20, on the other hand, the inner peripheral wall of side coaming 21 is connected to the crossbeam, can strengthen the intensity and the stability of side coaming 21, prevents that side coaming 21 from warping or damaging.
As shown in fig. 3 and 5, in the present embodiment, the heat insulation knob 100 further includes: the elastic member 30 is pressed and stopped between the bottom wall of the sliding groove 121 and the cross beam, and the heat insulation sleeve 20 is always pushed to the first position when the elastic member 30 stretches.
That is, when the user drives the sleeve 20 to slide from the first position to the second position, the bottom of the cross beam and the sliding groove 121 presses the elastic member 30, and when the user's force applied to the sleeve 20 is removed, the elastic member 30 stretches to spring the sleeve 20 back from the second position to the first position.
Therefore, when the user does not operate the heat insulation knob 100, the heat insulation sleeve 20 is always located at the first position, and the hand-held part 12 is covered by the heat insulation sleeve 20 to prevent the hand-held part 12 from being roasted at high temperature, so that the hand-held part 12 is always in a low-temperature state, and convenience is brought to the user.
Further, a spring seat 111 is provided on the top of the base 11, the spring seat 111 is accommodated in the sliding groove 121, and the elastic member 30 is provided on the spring seat 111. By arranging the spring seat 111 at the top of the base 11, not only can the assembly stability of the elastic element 30 be improved, but also the elastic element 30 is prevented from moving to influence the elasticity, so that the performance of the heat insulation knob 100 is improved, and convenience is provided for the assembly of the elastic element 30.
