Lever type puller

Abstract

The invention discloses a lever type puller, comprising a threaded head, wherein the threaded head is of a stepped round shaft structure; one end of the threaded head is of an external thread structure for connecting a pin roll; an obliquely-opened groove is arranged at the other end of the lever type puller; a movable hinge is arranged in the obliquely-opened groove and a connecting rod is connected to the movable hinge; a stress application rod is hinged at the other end of the connecting rod; a support rod is hinged in the middle of the connecting rod; and the threaded head, the support rod and the stress application rod are mutually parallel. The invention has the benefits that: (1) a knocking force is applied from top to bottom, and accords with the human mechanics so as to generate the optimal acting force and be more convenient and force-saving for users to use; (2) since the force does not directly act on the threaded head, a greater shake force at the holding part can be avoided and hands are prevented from being hurt; (3) the obliquely-opened groove is arranged to facilitate the connection between the connecting rod and the threaded head; and (4) the lever type puller has a simple and reasonable structure so as to be more widely applied to various occasions to a greater extent.

Description

Technical field [0001] The invention relates to a lever type horse puller. Background technique [0002] In the process of mechanical manufacturing, the taper pin 1'is often used to locate the joint between the two parts. When disassembling, the extractor 2'is used (see diagram figure 1 ) To pull out the shaft pin 1'and separate the parts. During the disassembly process, it will be restricted by the external environment. It can only be used in situations where the external is not restricted. Figure 5 In the external environment, the extractor 2'can no longer be used; and, when using the extractor 2', it relies on the movement of the hammer head 3'from bottom to top to hit the convex end surface of the handle 4' , And the force generated to make the shaft pin 1'pull up, and the human body mechanics is only the best performance from the top to the bottom. This must be when the puller 2'is used, the force will be affected Restriction; At the same time, when the hammer head 3'hits ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems that the puller currently in use cannot use force, is easy to injure hands, and is not suitable for complex external environments, the present invention provides a device that conforms to human body mechanics and can produce the best force without shock. Lever type puller for the applicable occasions has been greatly increased
