Portable mounting and dismounting type lever pin puller

Abstract

The invention discloses a portable mounting and dismounting type lever pin puller. The portable mounting and dismounting type lever pin puller comprises a threaded head. The threaded head is of a stepped round shaft structure. One end of the threaded head is provided with an external thread structure used for being connected with a shaft pin, and the other end of the threaded head is connected with an adjustable type connecting rod, wherein the connection position of the adjustable type connecting rod is adjustable. A force application rod is hinged to the other end of the adjustable type connecting rod. An adjustable type support rod is connected to the middle of the adjustable type connecting rod, wherein the connection position of the adjustable type support rod is adjustable. The threaded head, the adjustable type support rod and the force application rod are parallel to one another. The portable mounting and dismounting type lever pin puller has the beneficial effects that knocking force is applied from top to bottom, the portable mounting and dismounting type lever pin puller meets body-mechanics and generates the optimal application force, and more convenience is achieved and more labor is saved when a user uses the portable mounting and dismounting type lever pin puller; due to the fact that the force is not directly applied to the threaded head, large vibrating force cannot be generated at a hand-holding position, and the hand cannot be hurt; the distance between the adjustable type support rod and the threaded head and the height of the adjustable type support rodare adjustable, and therefore, the portable mounting and dismounting type lever pin puller is not influenced by the height of a working table; and the portable mounting and dismounting type lever pinpuller is simple and reasonable in structure, and application occasions are remarkably increased.

Description

technical field [0001] The invention relates to a portable detachable 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; Sim...
