Description

Binding band hand pulling device with safe device

The utility model relates to a kind of packing tape hand controller, particularly relate to a kind of can so that the packing tape hand controller the operation on safer packing tape hand controller with safety device.

General hand controller all has a handle, can rotate with respect to a body, so that drive an axle by a ratchet, and the rotational action of utilizing this axle is twisted the stringing rope, but, in strand stringing rope, it does not have any safety device and fixes this handle, make this handle still can rotate with respect to this body, make that this axle can also be back then unclamp the tight cotton rope of strand, so the article that utilize this hand controller binding to live also can unclamp, the article that this kind situation not only makes binding live might come loose and damaged, the article that drop more likely hurt the people, so quite dangerous.

Because many shortcomings of the general hand controller of using always through research improvement design repeatedly, are developed the packing tape hand controller that the utlity model has safety device finally.

Main purpose of the present utility model is, overcome the shortcoming of prior art, and provide a kind of novel packing tape hand controller with safety device, it can prevent that handle and body are separated out, make the tight cotton rope on axle of ratchet and strand can not get loose phenomenon, unclamp and hurt the people and can prevent to be tied article effectively, make the packing tape hand controller safer in operation.

The purpose of this utility model is realized by following technical scheme.

A kind of packing tape hand controller with safety device, include a body and a handle, both utilize an axle and combine pivotally, a pair of ratchet is fixed on the axle and with axle and rotates together, one screens element is arranged on the body the inside versatilely, and give ejection by elastic element and go to engage this to ratchet, a driver element is arranged on handle the inside versatilely, and gives ejection by elastic element and go to engage this to ratchet; It is characterized in that:

On body, be provided with one up extend collude linear element, and on driver element, be provided with a perforate, this perforate will be colluded linear element and be passed and block driver element, and this driver element and handle can not move to the direction that is separated from body, get loose and prevent to be twisted tight cotton rope.

Compared with the prior art the utility model has tangible advantage.By above technical scheme as can be known, the utility model

A kind of packing tape hand controller with safety device, comprise a body and a handle, it utilizes an axle to combine, one ratchet is fixed on the axle, one screens element is arranged on the body the inside and can engages this ratchet, one driver element is arranged on the handle the inside and can engages this ratchet, wherein principal character be on body, be provided with one up extend collude linear element, and on this driver element, be provided with a perforate, can collude linear element for this and pass and block this driver element, can make this driver element and handle can not move, get loose and can actv. prevent to be twisted tight cotton rope to the direction that is separated from body.

In sum, the utility model can prevent that handle and body are separated out, make the tight cotton rope on axle of ratchet and strand can not get loose phenomenon, unclamp and hurt the people and can prevent to be tied article effectively, make the packing tape hand controller safer in operation, and have substantial practicality, so the utility model is a novel structure in fact, is suitable for practical new design.

Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Fig. 1 is the block diagram that the utlity model has the packing tape hand controller of safety device;

Fig. 2 and Fig. 3 are part section action scheme drawing of the present utility model.

Below in conjunction with accompanying drawing and preferred embodiment, to concrete structure of the present utility model, feature and effect, describe in detail as after.

See also Fig. 1 to shown in Figure 3, the utlity model has the packing tape hand controller of safety device, its whole pair of packing tape hand controller comprises a body 10 and a handle 20, both utilize an axle 30 to combine with the pivoting structure, a pair of ratchet 31 is fixed on the axle 30, and and axle 30 is rotated together, one screens element 11 is arranged on body 10 the insides versatilely, and giving ejection by spring 12 makes it go to engage this to ratchet 31, one driver element 21 is arranged on handle 20 the insides versatilely, and gives ejection by spring 22 and make it go to engage this to ratchet 31.Operation time, when handle 20 near the place of body 10 when rotating away from the direction of body 10, driver element 21 can engage ratchet 31 and order about ratchet 31 and rotate, and makes axle 30 to rotate and can be used to twist the stringing rope.Aforesaid hand controller structure is the hand controller structure that belongs to known, wherein, in strand stringing rope, and when the direction of handle 20 past bodies 10 moves, it tends to hand controller is remained on the tight state of this kind strand, can prevent it separately yet this handle 20 and body 10 there is no any safety device, and can't prevent that screens element 11 is separated from this to ratchet 31, so make the phenomenon that gets loose is arranged often by the tight cotton rope of strand.

The improved structure of the utility model promptly is to provide a kind of packing tape hand controller with safety device, and it can prevent that handle 20 and body 10 are separated out each other; This safety device mainly is included in to dash forward on the body 10 establishes a pair of body 14 that colludes, and on driver element 21, be provided with and be somebody's turn to do colluding body 14 corresponding a pair of holes 24, so that can be for wearing this to colluding body 14, and make handle 20 and body 10 can not be separated from each other each other to hold; See also shown in Figure 3, when pulling driver element 21, so that will be somebody's turn to do when colluding body 14 and be fastened on this to hole 24 the insides, this handle 20 can be caught on and can't be moved away body 10, therefore it can be so that the tight cotton rope on axle 30 of this ratchet 31 and strand be unlikely the phenomenon that gets loose, so can prevent tied article of living from unclamping and hurt the people.

Claims (1)

1, a kind of packing tape hand controller with safety device, include a body and a handle, both utilize an axle and combine pivotally, a pair of ratchet is fixed on the axle and with axle and rotates together, one screens element is arranged on the body the inside versatilely, and give ejection by elastic element and go to engage this to ratchet, a driver element is arranged on handle the inside versatilely, and gives ejection by elastic element and go to engage this to ratchet; It is characterized in that:

On body, be provided with one up extend collude linear element, and on driver element, be provided with a perforate, this perforate will be colluded linear element and be passed and block driver element, and this driver element and handle can not move to the direction that is separated from body, get loose and prevent to be twisted tight cotton rope.
