Abstract

Disclosed is a tension spring of a potato machine. Two opposite ends of a cylindrical spring body extend to form a drag hook respectively, the drag hook at the right end of the spring body is parallel to the axial direction of the spring body, and the included angle between the drag hook at the left end of the spring body and the axial direction of the spring body is larger than 90 degrees. During usage, the drag hook at the left end of the spring body is hung into a hole of a support, and the drag hook at the right end of the spring body matches with parts on the support of the potato machine so that the parts connected onto the support of the potato machine can retract flexibly under action of external force by aid of the tension spring. The tension spring of a potato machine is simple in structure and applicable to being used with the support of the potato machine.

Description

The extension spring of a kind of potato machine

Affiliated technical field

The utility model relates to a kind of extension spring of adopting special hook structure, relates in particular to a kind of and the matched extension spring of potato machine.

Background technique

The extension spring of in daily life, using, generally form by columniform spring body and two drag hooks, and two drag hooks are by the two ends of spring body and the spring body is tangent extends, and two hooks are on same horizontal line, the extension spring of using on the potato machine product now, because the structure of potato machine part is special, usage requirement is not satisfied in the extension spring of general structure, in order to adapt to product needed, also to make certain improvements to drag hook.

Summary of the invention

The purpose of this utility model provides the extension spring of a kind of potato machine, is the drag hook of existing extension spring is done further improvement, thereby satisfies the requirement of the extension spring of using on the potato machine.

The purpose of this utility model is achieved in that the extension spring of a kind of potato machine, two opposite ends at cylindrical spring body are extended a drag hook separately, the drag hook of spring body right-hand member and spring axon are to paralleling, the drag hook of spring body left end and spring axon are spent greater than 90 to angle, during use, the drag hook of spring body left end is hung in the hole of support, and the drag hook of spring body right-hand member cooperates with part on the potato machine support, makes the part that is connected on the potato machine support rely on extension spring to shrink freely under the effect of external force.

The utility model has the advantages that, the extension spring of a kind of potato machine, the drag hook of spring body right-hand member and spring axon are to paralleling, the drag hook of spring body left end and spring axon are spent greater than 90 to angle, make the part that is connected on the potato machine support under the effect of external force, rely on extension spring to shrink freely, it is simple in structure, is suitable for and the supporting use of potato machine support.

Fig. 1 is a plan view of the present utility model;

Fig. 2 is a left view of the present utility model.

Among the figure: 1, spring body; 2, drag hook; 3, drag hook.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

A kind of potato machine extension spring as shown in fig. 1, extend a drag hook 2,3 separately in two opposite ends of cylindrical spring body 1, the drag hook 3 of spring body 1 right-hand member and spring axon are to paralleling, the drag hook 2 of spring body 1 left end is spent greater than 90 to angle with the spring axon, during use, the drag hook 2 of spring body 1 left end is hung in the hole of support as shown in Figure 2, and the drag hook 3 of spring body 1 right-hand member cooperates with part on the potato machine support, makes the part that is connected on the potato machine support rely on extension spring to shrink freely under the effect of external force.

Claims

1. potato machine extension spring is extended a drag hook separately in two opposite ends of cylindrical spring body, it is characterized in that: the drag hook of spring body right-hand member and spring axon be to paralleling, the drag hook of spring body left end and spring axon to angle greater than 90 degree.
