Abstract

The invention discloses a convenient-to-unlock positioning rod. The positioning rod comprises a base, a control rod and a locking device, wherein the control rod comprises a force applying end and a stressed end; the force applying end is connected with a workpiece; the locking device is arranged on the base; the control rod comprises a tension spring section, a first rod section and a second rod section which are sequentially connected from the stressed end to the force applying end; the horizontal size of the second rod section is greater than that of the first rod section; the locking device comprises a clamping claw which is positioned on the side surface of a movement locus of the control rod; the middle of the clamping claw is hinged to the base; a pressing spring is connected between one end of the clamping claw and the base; a groove which is used for holding the second rod section is formed in the other end of the clamping claw; the length of the groove is smaller than the elastic deformation of the tension spring section. According to the positioning rod, the control rod only needs to be lengthened, so that the second rod section is not in contact with the groove of the clamping claw, and then the control rod can be unlocked by moving to the reverse direction. The control rod can be unlocked without two hands or two people, so that the unlocking step is simplified, and the unlocking operation is more convenient.

Description

technical field [0001] The invention belongs to the technical field of devices for limiting the movement of parts. Background technique [0002] The positioning rod refers to the rod body that will lock itself when it reaches a certain position. The locked position is often the limit position. The positioning rod is widely used in the mechanical field. However, the locking device of the existing positioning rod can lock the rod body in all directions, and when it needs to be unlocked, the locking device can only be disassembled, so that the rod body can be unloaded and unlocked. [0003] There are some problems in the existing unlocking device: when unlocking, the locking device needs to be unloaded, and the rod body must be moved out of the locked position at the same time, which must be done by one person's two hands, or two people. Unlocking the rod body is very inconvenient. Contents of the invention [0004] The invention provides a convenient unlocking positioning ...
