Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

The stone material mounting fixture of this embodiment, its structure is as shown in fig. 1, fig. 2, including two centre gripping arms 1 and spring 2, the one end of centre gripping arm 1 all is equipped with chuck 3, and the other end all is provided with handle 10, and handle 10 overcoat has handle cover 11 to improve user's comfort level. The middle parts of the two clamping arms 1 are pivoted through a pivot 4, so that the two clamping arms 1 can rotate relatively through the pivot 4. The spring 2 is arranged on the pivot 4, and the two chucks 3 are mutually clamped under the elastic force of the spring 2. Chuck 3 is extended by centre gripping arm 1 and forms, and it includes straight portion 5 and sloping 6, and sloping 6 connects between the straight portion 5 of the 1 end of centre gripping arm, is "eight" word form between two sloping 6, can enlarge the centre gripping scope, and straight 5 has increased the contact surface of stone material and chuck 3 for stabilize the stone material of required centre gripping, and when two chucks 3 centre gripping mutually abut on.

The clamping head 3 is externally sleeved with a clamping sleeve 7 with one end opened, and the structure of the clamping sleeve 7 is shown in figure 3. The clamping surface of the clamping sleeve 7 is provided with wavy bulges 12 which are matched with the bulges 12 on the straight part 5, and the bulges 12 are used for increasing the friction force of the clamping surface. In order to prevent the clamping sleeve 7 from loosening or slipping off in the using process, a long opening 8 is arranged on the side face of the opening end of the clamping sleeve 7 and the inclined portion 6 of the chuck 3, a screw 9 penetrates through the long opening 8 to fasten the clamping sleeve 7 on the clamping arm 1, the long opening 8 is formed by reducing the opening end of the clamping sleeve 7 to the other end, the narrowest part of the long opening 8 is smaller than the size of a stud of the screw 9, and the clamping sleeve 7 can be better clamped on the clamping arm 1.

Wherein, the handle sleeve 11 and the clamping sleeve 7 are made of rubber. The operation of the embodiment is simple, and only by pressing the handle 10, the chuck 3 can rotate relatively through the pivot 4 to open, so that the bulge of the clamping surface contacts with the stone as much as possible, the friction force between the two is increased, and the fixing effect can be achieved.
