Abstract
The utility model discloses a fast knife-retreating structure of a metal rotary-cut pipe cutting knife. The structure comprises a thread pawl, a screw rod, a pressure spring, a blade, a blade frame, a main body and a handle. The thread pawl is fixed to the blade frame through a pin, a thread spring is arranged between the thread pawl and the blade frame, the screw rod is fixed to the main body, the blade frame is embedded in a concave guide rail of the main body through a convex rail, and the pressure spring is sleeved between the blade frame and the main body. The structure is simple and practical and convenient to operate, achieves fast knife-retreating, and greatly improves work efficiency.
Description
Technical field
The utility model relates to a kind of metal rotary-cut pipe cutter, especially relates to a kind of metal rotary-cut pipe cutter rapid return structure.
Background technology
Metal rotary-cut pipe cutter is a kind of for the instrument of metal circular tube from radially cutting off, at present careless every profession and trade is to the extensive use of pipe, so that metal rotary-cut pipe cutter becomes a kind of cutting tool commonly used, and the operation of the withdrawing of metal rotary-cut pipe cutter of the prior art is cumbersome, the withdrawing time is long, has reduced operating efficiency.
The utility model content
Technical problem to be solved in the utility model is: a kind of metal rotary-cut pipe cutter rapid return structure is provided, and simple and practical, easy to operate, realized rapid return, greatly improved operating efficiency.
For solving the problems of the technologies described above, the technical solution of the utility model is: metal rotary-cut pipe cutter rapid return structure, comprise screw thread ratchet, screw mandrel, compression spring, blade, blade holder, main body and handle, described screw thread ratchet is fixed on the blade holder by pin, be provided with the screw thread spring between described screw thread ratchet and the blade holder, described screw mandrel is fixed on the described main body, described blade holder embeds on the matrix guide rail of described main body by the convex track, and described compression spring is sleeved in the middle of described blade holder and the main body.
Adopted technique scheme, the beneficial effects of the utility model are: because the screw thread ratchet of metal rotary-cut pipe cutter rapid return structure is fixed on the blade holder by pin, be provided with the screw thread spring between screw thread ratchet and the blade holder, screw mandrel is fixed on the main body, blade holder embeds on the matrix guide rail of main body by the convex track, and compression spring is sleeved in the middle of described blade holder and the main body, therefore, click the screw thread ratchet
Tension force by compression spring makes screw thread ratchet and screw mandrel break away from fast, make the diameter between blade holder and the main body reach maximum, when the diameter that will dwindle between blade holder and the main body, with hand push feed horse, will dwindle fast the diameter between blade holder and the main body, the screw thread ratchet can get up by auto lifting, thereby realizes rapid return.The utility model, simple and practical, easy to operate, greatly improved operating efficiency.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Such as Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4 and Fig. 5 are common, metal rotary-cut pipe cutter rapid return structure, comprise screw thread ratchet 1, screw mandrel 2, compression spring 3, blade 4, blade holder 5, main body 7 and handle 8, screw thread ratchet 1 is fixed on the blade holder 5 by pin 12, be provided with screw thread spring 11 between screw thread ratchet 1 and the blade holder 5, screw mandrel 2 is fixed on the main body 7, blade holder 5 embeds on the matrix guide rail 14 of main body 7 by convex track 13, it is middle with main body 7 that compression spring 3 is sleeved on blade holder 5, blade 4 is installed on the blade holder 5 by blade shaft 6, and roller 9 is installed on the main body 7 by roller shaft 10.
During use, click screw thread ratchet 1, tension force by compression spring 3 makes screw thread ratchet 1 and screw mandrel 2 break away from fast, make the diameter between blade holder 5 and the main body 7 reach maximum, when the diameter that will dwindle between blade holder 5 and the main body 7, with hand push feed horse 5, will dwindle fast the diameter between blade holder 5 and the main body 7, screw thread ratchet 1 can get up by auto lifting, thereby realizes rapid return.
The utility model, simple and practical, easy to operate, greatly improved operating efficiency.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
