Set up the different semicircle arc recess 502 of a plurality of radiuses simultaneously, several kinds of radiuses that can the adaptation is commonly used evaporation dish 10 for when pressing from both sides and getting corresponding radius evaporation dish 10, the matching degree is better, and the centre gripping is more steady.

The radius of the semi-circular groove 502 closer to the hinge portion 4 is smaller, and the evaporation pan 10 can be easily moved from the semi-circular groove 502 with the largest radius of the left and right clamp openings to the semi-circular groove 502 with the matched radius.

Example 3

As shown in fig. 3-4, the clip column 8 is composed of a connection column 801 and a small ball 802 arranged at the end of the connection column 801, the diameter of the end section of the connection column 801 is smaller than that of the small ball 802, the small ball 802 is fixed with the inner side of the handheld portion 3 through the connection column 801, a spherical groove 901 matched with the small ball 802 is arranged in the clamping groove 9, a half-opened U-shaped expansion groove 902 is arranged on the side wall of the spherical groove 901, and the small ball 802 is squeezed and clamped into the spherical groove 901 through external force. The opening of the spherical groove 901 is provided with a bell mouth 903, and the diameter of the small end of the bell mouth 903 is smaller than that of the small ball 802, so that the small ball 802 can enter the spherical groove 901 through extrusion and be clamped. The other structure is the same as embodiment 1.

The end of the clamping column 8 is provided with a small ball 802, and the small ball 802 is captured by the spherical groove 901 with the U-shaped expansion groove 902 through elastic deformation of the U-shaped expansion groove 902 within the elastic limit by pressing the small ball 802 into the spherical groove 901. When the small ball 802 is clamped into or pulled out of the spherical groove 902, larger extrusion force needs to be overcome, more stable and reliable secondary safety guarantee can be formed, and the shaking of fingers does not easily cause the clamping structure to loosen. In addition, the structure of this card post, draw-in groove is comparatively simple, can used repeatedly.
