Abstract
The utility model discloses a screw disc compasses which comprises two support feet and a support frame, wherein, the two support feet are connected with the support frame. The utility model is characterized in that screw rods are arranged on the two support feet; screw discs are fixed on the middle of the screw rods; and the support frame is made of elastic materials. The screw disc compasses is made of metal materials, and the support frame is made of steel sheets. Compared with the prior art, the utility model has the advantages that the distance between the two support feet can be regulated through the screw rods, and the regulation precision is high; the structure is simple, and the installation is convenient; and the support frame is made of steel sheets, when the screw discs are rotated for regulating the support feet, the support feet can automatically open because of the elasticity of the steel sheets, so the use is convenient.
Description
Technical field:
The utility model relates to a kind of spiral shell dish compasses.
Background technology:
Compasses of the prior art all are manual adjustments usually, and degree of regulation is smaller, and it is not too convenient to use.
Summary of the invention:
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of spiral shell dish compasses are provided.
The technical scheme in the invention for solving the above technical problem is: these spiral shell dish compasses, comprise two legs and a support, two legs are connected with support, it is characterized in that two legs are provided with screw rod, the screw rod middle part is fixed with the spiral shell dish, and support adopts elastomeric material.
Spiral shell dish compasses described in the utility model adopt metal to make, and support adopts steel disc.
The utility model compared with prior art has the following advantages and effect: 1, can regulate two distances between the leg, degree of regulation height by enough screw rods.2, simple in structure, easy for installation.3, support adopts steel disc, and when rotating spiral shell dish adjusting leg, the elastic force of steel disc can open leg automatically, and is easy to use.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment:
Referring to Fig. 1, the utility model embodiment spiral shell dish compasses comprise that two legs 1 and 3, two legs 1 of a support are connected with support 3, and two legs are provided with screw rod 5, and screw rod 5 middle parts are fixed with spiral shell dish 6, and support 3 adopts elastomeric material to make.
Present embodiment spiral shell dish compasses adopt metal to make, and support 3 adopts steel disc.
The utility model is regulated two distances between the leg 1 with spiral shell dish 6 rotating screw bolts 5, thereby can very accurately finely tune, and has improved degree of regulation.Support 3 adopts steel disc, and when rotating spiral shell dish 6 adjusting legs 1, the elastic force of steel disc can open leg 1 automatically, uses more convenient.
