Abstract

A safety hook structure of a fixing clip, comprising: a clamping jaw, a fixed handle, a spring, a connecting rod and a movable handle, it mainly lies in: the free end of the movable handle is pivoted with a safety hook, the safety hook is close to the free end of the fixed handle, and when the jaw clamps an object, the safety hook transfers the clamping part to clamp the adjusting bolt, so that even if the release rod is pressed, the distance between the fixed handle and the free end of the movable handle is fixed, the release rod cannot smoothly release the jaw, and the release prevention can be ensured.

Description

The safety door hook structure of fixing pincers

Technical field

The utility model relates to a kind of fixedly pincers, particularly a kind of safety door hook structure of fixedly pincers, and it is at this activity handle free end safety door hook that is pivoted, and can prevent that fixing pincers from unclamping.

Background technology

The existing fixed pincers, this fixing pincers front end folder jaw is made of a fixed jaw and a movable jaw, and the front end of a fixed handle is fixed in this fixed jaw assembling, and the terminal spiral shell of this fixed handle is provided with one and adjusts bolt.This movable jaw is articulated near the fixed handle front end inboard, can cooperate this fixed jaw to produce the clamping action.One movable handle, this activity handle front end is pivoted to this outside, movable jaw rear end by pivot.And should articulate mutually with a pivot and a connecting rod front end near the activity handle front end inboard, in then being extended into by this fixed handle lateral opening groove place, this connecting rod end contacts at the front end of this adjustment bolt.One liberation bar, this liberation bar relies on pivot to be pivoted near this activity handle rear inside, and this liberation bar leading edge can be supported and be compeled to connecting rod one side.One spring, this spring one end is assembled in this movable jaw rear end, and the other end is assembled in this fixed handle inside.In view of the above, adjust bolt and can change connecting rod angle between fixed handle and the movable handle in the terminal adjustment of fixed handle, just can the adjustment movable jaw bite between fixed jaw between the crack, make it to different thickness or justify all effectively clamping of flat article.The application of force is pressed and is held when between this fixed handle and movable handle, when making movable handle rely on fixed handle, then can be that support arm sees through preceding end pivoting and provides thrust in the outside, movable jaw rear end with the connecting rod, make that movable jaw is that axle is bitten fixed jaw with the pivot, just can reach the fixation of interlock gripping objects.To liberate the terminal application of force of bar and rely on movable handle, this liberation bar can pivot be an axle then, pushes connecting rod with front end, and cooperates the pulling force of spring, just can moment this movable jaw be pulled away from this fixed jaw.

Yet its above-mentioned existing fixed pincers still have the following problems point:

These existing fixed pincers do not have safety door hook, so in a single day press or false touch liberation bar, the movable jaw of this folder jaw are unclamped, and discharge clamp position, if carrying out dangerous operation this moment, then the abrupt release clamping will bring danger immediately.

Be with, at the existing problem points of above-mentioned existing structure, how to develop a kind of innovation structure that has more desirable practicality, the ardent hope of real consumer institute also is that relevant dealer must make great efforts target and the direction that research and development break through.

In view of this, the designer this in manufacturing development and the design experiences of being engaged in Related product for many years, at above-mentioned target, in detail after design and the scrupulous assessment, eventually the utility model of a true tool practicality.

Summary of the invention
