Abstract

The present invention discloses a kind of jack retractor device, comprises fixed underpan, sole, pillar, external spring, lifting cake, built-in spring, fixed disc and spiral nail; Described pillar is positioned at fixed underpan home position, described sole is positioned at fixed underpan side, described external spring is positioned at lower rod end, described built-in spring is positioned at pillar upper end, described lifting cake is between external spring and built-in spring, described fixed disc is positioned at above pillar, and described spiral nail is positioned at above fixed disc through fixed disc.Because this jack retractor device adopts the lifting cake of middle part to carry out jack-up, will extremely be convenient to laying of jack like this.When putting down the weight by jack-up, because external spring can provide certain cushion effect, jack so just can be avoided to be occurred by the accident smashed.

Description

A kind of jack retractor device
Technical field
The present invention relates to a kind of jack retractor device.
Background technology
Jack is that part is lifted as equipment, the light little weight-lifting equipment of jacking weight in stroke by top bracket or bottom claw in one rigidity top.Because its structure is simple, flexibly small and exquisite, be easy to carry, practical and be subject to the favor of people.Mostly existing jack is directly weight jack-up to be come by retractor device top, and jack is laid more difficult in this process, and when putting down the weight by jack-up because acceleration due to gravity easily causes jack to be smashed.
Summary of the invention
The technical problem to be solved in the present invention is to realize a kind of jack retractor device, and this device is convenient to lay when jack-up weight, and jack can not be caused to be occurred by the accident smashed because of discontinuity when putting down the weight by jack-up.
For solving the problem, the present invention adopts following technical scheme: a kind of jack retractor device, comprises fixed underpan, sole, pillar, external spring, lifting cake, built-in spring, fixed disc and spiral nail; Described pillar is positioned at fixed underpan home position, described sole is positioned at fixed underpan side, described external spring is positioned at lower rod end, described built-in spring is positioned at pillar upper end, described lifting cake is between external spring and built-in spring, described fixed disc is positioned at above pillar, and described spiral nail is positioned at above fixed disc through fixed disc.
As preferably, below described lifting cake, a protruding circular ring is set.
As preferably, described external spring is arranged on outside protruding circular ring.
As preferably, described built-in spring diameter is less than lifting cake internal diameter.
The invention has the beneficial effects as follows: because this jack retractor device adopts the lifting cake of middle part to carry out jack-up, will extremely be convenient to laying of jack like this.Separately, when putting down the weight by jack-up, because external spring can provide certain cushion effect, jack so just can be avoided to be occurred by the accident smashed.
Accompanying drawing explanation
Fig. 1 is the block diagram of a kind of jack retractor device of the present invention.
Detailed description of the invention
Consult a kind of jack retractor device shown in Fig. 1, comprise fixed underpan 1, sole 2, pillar 3, external spring 4, lifting cake 5, built-in spring 6, fixed disc 7 and spiral nail 8; Described pillar 3 is positioned at fixed underpan 1 home position, described sole 2 is positioned at fixed underpan 1 side, described external spring 4 is positioned at pillar 3 lower end, described built-in spring 6 is positioned at pillar 3 upper end, described lifting cake 5 is between external spring 4 and built-in spring 6, described fixed disc 7 is positioned at above pillar 3, and described spiral nail 8 is positioned at above fixed disc 7 through fixed disc 7.
Arrange a protruding circular ring 9 below described lifting cake 5, described external spring 4 is arranged on outside protruding circular ring 9, and described built-in spring 6 diameter is less than lifting cake 5 internal diameter.
The invention has the beneficial effects as follows: because this jack retractor device adopts the lifting cake of middle part to carry out jack-up, will extremely be convenient to laying of jack like this.When putting down the weight by jack-up, because external spring can provide certain cushion effect, jack so just can be avoided to be occurred by the accident smashed.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within scope.
