Description

Push the flexible nail puller of release self-locking

Technical field

The utility model relates to a kind of hand-held tool, particularly a kind of flexible nail puller of release self-locking of pushing.

Background technology

The nail puller of prior art generally all is fixed dimension of a kind of specification, and length can not change, and when using like this, often needs to adopt according to environment requirement the nail puller of different length under different environment, very trouble.For this reason, a kind of flexible nail puller occurred, its length can be regulated within the specific limits; though but the flexible nail puller of prior art can be regulated its length within the specific limits; but can not form locking after the length variations, use regular meeting and occur becoming flexible, cause producing safety problem.Though perhaps can form locking, the mode of locking is very loaded down with trivial details, can not automatically lock inconvenient operation.

The utility model content

The purpose of this utility model is exactly in order to solve the problem that above-mentioned prior art exists, a kind of flexible nail puller of release self-locking of pushing to be provided.

In order to achieve the above object, the utility model has adopted following technical scheme: a kind of flexible nail puller of release self-locking of pushing comprises wrenching bar and is connected playing ailhead and shoveling head of wrenching bar two ends that wrenching bar comprises bassoon, tubule and locking mechanism; Tubule is nested in can be along the bassoon telescopic moving in the bassoon, and locking mechanism forms locking to the multiple flexible state of tubule;

Described locking mechanism is for pushing the release self-locking mechanism, and this pushes the release self-locking mechanism has a plurality ofly, correspondingly on the described tubule is provided with a plurality of lockholes, respectively pushes the release self-locking mechanism and is inlaid in respectively on the corresponding lockhole; Respectively push the release self-locking mechanism and all comprise a button and a spring; Button is inlaid on the lockhole and can moves up and down along lockhole, and spring is connected the elastic force that self-locking is provided to button between the inwall of button and tubule.

The described bassoon front end mouth of pipe is connected with the block piece of a undergauge, and anterior tube wall is provided with a button hole that is used to pass button; Described block piece is provided with in the side corresponding to button and makes things convenient for button to enter the inclined-plane of bassoon.

The top size of described button is suitable with the lockhole of tubule, and the bottom of button is more bigger than top, forms a limited step between top and the bottom, and the last end periphery of button is an arcuate structure.

Also comprise gum cover, this gum cover is sleeved in the bassoon.

The utility model is pushed the nail puller that the flexible nail puller of release self-locking can replace traditional a plurality of different sizes, can be adjusted to different length as required and form locking automatically, need only push button during release downwards and can realize release, and is simple to operation.

The specific embodiment

Referring to Fig. 1, Fig. 2, cooperate referring to Fig. 3, Fig. 4.The flexible nail puller of release self-locking of pushing of the present utility model, what comprisewrenching bar 1 and be connected the wrenching bar two ends playsailhead 2 and shovel 3.Wrenching bar 1 is length-adjustable wrenching bar, and this wrenching bar comprisesbassoon 11,tubule 12 and pushes release self-locking mechanism 13; Tubule 12 is nested in thebassoon 11 can play the rear end thatailhead 2 is connected bassoon along the bassoon telescopic moving, andshovel 3 is connected the front end of tubule.

The release self-locking mechanism 13 of pushing in the utility model has a plurality of (present embodiment is 5), correspondingly ontubule 12 is provided with a plurality oflockholes 121, respectively pushes release self-locking mechanism 13 and is inlaid in respectively on the corresponding lockhole; Respectively push the release self-locking mechanism and all comprise abutton 131 and aspring 132;Button 131 is inlaid on the lockhole and can moves up and down along lockhole, andspring 132 is connected the elastic force that self-locking is provided to button between the inwall of button and tubule.

Thebassoon 11 front end mouths of pipe in the utility model are connected with theblock piece 14 of a undergauge, and anterior tube wall is provided with abutton hole 111 that is used to pass button;Block piece 14 is provided with in the side corresponding to button and makes things convenient for button to enter the inclined-plane 141 of bassoon.

The top size of thebutton 131 in the utility model is suitable with the lockhole of tubule, and the bottom of button is more bigger than top, forms alimited step 1311 between top and the bottom, and the last end periphery of button is anarcuate structure 1312.

The utility model also can comprisegum cover 4, and thisgum cover 4 is sleeved in the bassoon 11.Wrenching bar is shielded.

The flexible nail puller of release self-locking of pushing of the present utility model is when regulating length, only need to push the button that is arranged in the bassoon button hole downwards with a hand, make it deviate to unlock (referring to Fig. 6) from the button hole of bassoon, promptly available another pulls moving tubule and regulates length.After being adjusted to Len req, the button that is in corresponding gear promptly pops up under the effect of spring, is stuck in again and forms locking (referring to Fig. 5) in the button hole of bassoon automatically.Nail puller can use under new length condition.
