Adjustable lever pin puller

Abstract

The invention discloses an adjustable lever pin puller which comprises a thread head; the thread head is of a ladder-shaped circular shaft structure; one end of the ladder-shaped circular shaft structure is used for connecting an external thread structure of a shaft pin; an adjustable connecting rod is connected to the end part of the other end of the ladder-shaped circular shaft structure, wherein the connecting position of the adjustable connecting rod is adjustable; a stress application rod is articulated to the other end of the adjustable connecting rod; the middle of the adjustable connecting rod is connected with an adjustable supporting rod the connecting position of which is adjustable; and the thread head, the adjustable supporting rod and the stress application rod are parallel to each other. The adjustable lever pin puller has the beneficial effects that: (1) the knocking force is from top to bottom, is in line with human body mechanics and generates the optimal acting force so that the adjustable lever pin puller is more convenient and saves labor when used by users; (2) as the force does not directly act on the thread head so that the larger vibrating force is not generated at a handclasp part and hands are not hurt; (3) the distance between the adjustable supporting rod and the thread head and the height of the adjustable supporting rod can be adjusted so that the adjustable lever pin puller is not affected by the height of a working table; and (4) the adjustable lever pin puller has a simple and reasonable structure and is suitable for more occasions to a great extent.

Description

technical field [0001] The invention relates to an adjustable lever pin puller. Background technique [0002] In the process of mechanical manufacturing, a tapered shaft pin 1' is often used for positioning at the joint of two parts, and a puller 2' is used for disassembly (see illustration 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, and the puller 2' can only be used in occasions where the outside is not restricted. Figure 12 When using the external environment, the puller 2' cannot be used; and, when using the puller 2', it depends 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 when the force is exerted from the top to the bottom. When using the puller 2', the force will be affected. Restriction; Simultaneou...

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. Hand, greatly increased the adjustable lever pin puller applicable to the occasion
