Below in conjunction with attached Fig. 1 and 2, the invention will be further described.

1, strut: be three foursquare pipes, form through spreading and suit.(1) pipe A: length is 986mm, and left end is connected with the back jacking block, has oblong aperture at distance right-hand member 60mm place, and the registration device with the B pipe in the time of in working order is connected.During packed state, the left side of frame is close in the right side.(2) pipe B; Length 1030mm.Left end be inserted in the pipe A in, right-hand member is inserted in the frame, and with the frame weld together.In the pipe of distance left end 60mm, registration device is housed.(3) pipe C: length is 1036mm, and left end is inserted in the square hole of tooth bar right-hand member, injects in the B pipe again, and right-hand member is connected with preceding jacking block, has several oblong aperture on the face up, is spaced apart 80～100mm, to be connected with the thrust ratchet.

2, frame: this frame is a blanked part, and latching device is the alloy aluminum diecasting.

3, tooth bar: length overall 80～200mm, this part right-hand member has square hole, is enclosed within on the pipe C, and thruster is equipped with on the top of square hole, and tooth bar is the thrust ratchet that relies on the thruster with being connected of pipe C, and this is the connection of a kind of brand new " work ".And the connection of background technology system " extremely ".

4, thruster: this is a kind of device of one-way only operation.Be made up of ratchet, spring, detent pin, locating dowel pin, spring makes ratchet downward all the time, and the locating dowel pin that is contained on the ratchet is stopped by the plane, makes the ratchet front end face keep vertically downward, injects in the oblong aperture of pipe C.When C pipe spurred forward, ratchet was pushed, and rotates counterclockwise, and was pressed in pipe C in appearance, and when running into next oblong aperture, ratchet is again in the inserting hole.Tooth bar thrust passes to pipe C by front end face vertically downward, presses the ratchet afterbody with hand or handle and lifts ratchet, and pipe C just can pull back in the square hole of tooth bar right-hand member.

5, registration device: be a kind of device of one-way only operation, be contained in the B pipe.When pipe B pulled out, this device entered sliding state, and when arriving the oblong aperture of pipe A, the location ratchet opens automatically, enters mode of operation.When force analysis showed in working order, ratchet is stressed to be balance, can not rotate.During withdrawal, press the location ratchet, and promote pipe B left, the location ratchet just enters sliding state, and to push the top, back to together with pipe B fast together.

Thruster and pipe C go up several oblong aperture and cooperate, and the distance before making between the jacking block arrival thing is divided into coarse regulation and two parts of fine adjustment.The former relies on the quantity of the oblong aperture that is drawn out to realize, and the latter leans on the length of tooth bar to realize.Generally speaking, the former is much larger than the latter, and these two parts in the background technology all rely on tooth bar to realize, so tooth bar length is very long.As long as finely tune, that therefore can do is very short at the design's middle rack, so claim short tooth bar, these two kinds of devices are vital in the design.

Registration device makes spreading or folding can the realization, when guaranteeing packing when 1.2 meters and the longest expansion 2.885 meters.

6, anti-drop device: be a kind of device of one-way only operation, be contained in the B pipe.Pull out and insert the A pipe when the B pipe, when the anticreep ratchet was positioned at the oblong aperture of A pipe, the anticreep ratchet opened automatically, prevented that the B pipe breaks away from the A pipe.

7, handle: the profile size is similar with the handle in the background technology, except promotion and locking rack, also plays and removes the thrust ratchet, the effect that pipe C is freely retracted.

8, operating principle and step:

(1) hold out against goods: product is in the state of packing before the general operation.

1. pipe B is pulled out (being referred to as one draws) from pipe A, when pipe B interior locating device is moved the oblong aperture position of pipe A to, can hear that locating ratchet jumps out, open sound stops drag, and registration device enters " mode of operation " automatically.

2. handle is opened, and clockwise rotates on earth, and this hour rack is retracted, and the square hole position of tooth bar right-hand member (hereinafter to be referred as the tooth bar right-hand member) just is close to frame.

3. the left hand tooth bar right-hand member of holding with a firm grip, right handgrip pipe C pulls out, preceding jacking block withstands goods (being referred to as two tops), the right hand is still held pipe C afterwards, draw back (being referred to as three moves back) along handle pipe C, when the thrust ratchet entered the oblong aperture of pipe C, pipe C was stuck, can not retreat, the distance that at this moment retreats can not go up the pitch-row (80～100mm) of oblong aperture greater than pipe C.To notice that in this step the right-hand member of tooth bar should be close to frame when preceding jacking block withstands goods, otherwise, will shorten effective usable length of tooth bar.The method that for this reason preferably adopts left hand and right hand outwards to spur simultaneously, C pulls out pipe, withstands goods.

4. left hand still keeps attitude 3., and the tooth bar right-hand member of holding with a firm grip is released tooth bar, and jacking block withstands goods (being referred to as four tops) once more before making.

5. pull handle and rotate counterclockwise, until the handle device auto lock that is locked.

As mentioned above, the key points for operation that hold out against goods are: one draw, move back on two tops, three, four tops, wherein move back on two tops, three, four tops are continuous smoothly action.

(2) unload the tooth bar strut:

1. unclamp latching device, handle clockwise rotates, and makes gear break away from tooth bar, and the right hand promotes the sinciput piece, contacts with frame until the tooth bar right-hand member, and at this moment the thrust ratchet also is inserted in the oblong aperture of pipe C, promotes to be stopped.

2. use handle (at this moment handle is above the thrust ratchet) or left hand to pin the thrust ratchet, make it break away from pipe C, the right hand still promotes preceding jacking block, and C is fully retracted the tooth bar right-hand member until pipe.

3. handle rotates counterclockwise, until being locked.In this process, tooth bar, pipe C, preceding jacking block will outwards move the distance of about 30mm.

4. regain location ratchet (its method is narrated) in " registration device ", pipe B is inserted among the pipe A fully.

9, characteristics:

(1) packing measurement is little: the design's packing measurement is 1200mm.

(2) maximum development size is 2885mm.

(3) setting range is big:

1. in use do not pull out when managing B, when promptly having only A pipe and C plumber to do, the setting range of development size is 1200mm～2045mm.

2. when the pipe B be positioned the device spreading the pipe A on the time, the setting range of development size is: 2045mm～2885mm.

3. comprehensive 1. 2. as can be known the design in use the setting range of development size be: 1200mm～2885mm.

(4) adopt short tooth bar: length overall 80～200mm.

Because it is 80～100mm that pipe C goes up the spacing of oblong aperture.Therefore in the operation that holds out against goods, move back when finishing when three, the distance between preceding jacking block and the goods is less than 80～100mm, and in four top processes, tooth bar is drawn out same length, and handle at work tooth bar mobile have only 25mm.Therefore at the handle end-of-job, when being locked, the tooth bar running length has only 105～125mm.Key was for 4 whens top, and the right-hand member of tooth bar is critical by frame, during two tops before jacking block head on goods, the right-hand member of tooth bar will head on frame.

(6) easy and simple to handle:

1. when the pipe rubbish goes out, press the anticreep ratchet, pipe B can pull out the A from pipe, jumps out as long as hear the location ratchet, and open sound can stop drag, and that pipe C pulls out from pipe B is simpler, pulls straight pipe C and withstands goods, one moves back smoothly, does not stop to just moving back.

2. when pipe is regained, press the location ratchet, pipe B can be retracted into pipe A, and pipe C is retracted into when managing B, needs only the afterbody of pinning the thrust ratchet with handle or left hand, and the right hand promotes the sinciput piece, and pipe C just can be retracted rapidly.

What need understand is: though the foregoing description is to the present invention's detailed explanation of contrasting; but these explanations, just to simple declaration of the present invention, rather than limitation of the present invention; any innovation and creation that do not exceed in the connotation of the present invention all fall within the scope of protection of the present invention.
