Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the invention, the meaning of "a plurality" is two or more unless otherwise specified.

In the description of the invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be construed broadly, e.g. as being fixed or detachable or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.

A multipurpose nail puller is disclosed, as shown in figures 1 to 9, and comprises a handle 1, a nail pulling head 2 at the front end of the handle and a swinging head 3 rotatably mounted on the nail pulling head. In order to facilitate nail pulling operation, the handle can adopt a telescopic structure, so that force application is more convenient.

The front end of the nail pulling head is provided with a fixed chuck 5, and the front end of the swinging head is provided with a movable chuck 6 corresponding to the fixed chuck. The swinging head is hinged with the nail pulling head through a hinge shaft 18, and when the swinging head and the nail pulling head rotate relatively, the operation of clamping and loosening the nail can be formed.

The support arm 4 is arranged at one end of the swing head different from the movable chuck, the support arm is provided with a groove 16 corresponding to the position of the fixed chuck, the support arm is provided with an auxiliary nail pulling mechanism 17, and when the movable chuck and the fixed chuck clamp a nail together, the support arm plays an auxiliary support role. The groove can ensure that the supporting arm does not interfere with the fixed chuck, and does not hinder the actions of clamping the nail or releasing the nail by the fixed chuck and the movable chuck.

The auxiliary nail pulling mechanism comprises a sliding component arranged at the tail end of the supporting arm. In an alternative embodiment the end of the support arm is provided with a u-shaped mounting 7, in which the axle 19 is turned on both side plates of the mounting, in which the pulley 8 is turned. In another alternative embodiment, the end of the supporting arm is provided with a seat plate 9, the seat plate is rotatably provided with a wheel shaft (two ends of the wheel shaft respectively extend out of two sides of the seat plate), and two ends of the wheel shaft are respectively provided with a pulley.

When the activity chuck cliies the nail with fixed chuck jointly, when pulling out the nail operation, along with the nail extracts the length increase, the pulley can produce the follow-up, when guaranteeing that the support arm remains the auxiliary stay effect throughout, the nail is extracted the angle and can not change usually, that is to say, owing to the follow-up of the sliding assembly who sets up, makes the nail at the in-process of extracting, can not the bending damage, has saved the operation of carrying out the repairment after the nail is pulled out, has improved the possibility of direct reutilization.

As shown in fig. 8 and 9, the auxiliary nail pulling mechanism further comprises an auxiliary support 10 mounted on the support arm. By way of example, the auxiliary support comprises a support screw screwed to the support arm, and under normal conditions, the end of the screw portion of the support screw is received in (the screw hole of) the support arm or the exposed length of the screw portion does not protrude beyond the outer edge of the pulley. When need not to use sliding assembly to produce the follow-up, need not consider during nail reutilization scheduling problem, can screw the supporting screw, make the supporting screw end stretch out the screw hole to the terminal protrusion of screw in sliding assembly (the outer fringe of well pulley) guarantees that the screw end supports the structure, for example, when unpacking, the screw end supports the boxboard at nail place, utilizes supplementary support piece to form stable support, reaches the purpose that the nail was extracted to the rapid stabilization. The auxiliary supporting piece and the sliding component have no influence on each other and can be selectively used, the universality of the nail puller is improved, application scenes are richer, the auxiliary supporting piece and the sliding component are used in a targeted manner, and the operation effect is better.

In an alternative embodiment, a hammer head 11 is arranged on the side of the pulling head, which is different from the swing head supporting arm. Utilize this tup can act as the hammer with this nail puller temporarily and use, for example, when pulling out the nail (or before pulling out the nail), if the nail is crooked state, can hold the handle, make this nail puller have tup one side to beat the nail, in time revise the nail to in the nail pulling operation, the maintenance that also can be better is by the intact of nail, the nail reutilization of being convenient for.

In order to improve the versatility and convenience of use, in an alternative embodiment, as shown in fig. 5, the fixed jaw has a first fixed clamping portion 12 and a second fixed clamping portion 13, and the movable jaw has a first movable clamping portion 14 and a second movable clamping portion 15.

The first fixed clamping part corresponds to the first movable clamping part, the second fixed clamping part corresponds to the second movable clamping part, the thickness of the edge of the first fixed clamping part is smaller than that of the second fixed clamping part, and the thickness of the edge of the first movable clamping part is smaller than that of the second movable clamping part. That is, the nails with thinner nail caps and smaller sizes or the nails with the nail caps closer to the surface of the box can be clamped between the first fixed clamping part and the first movable clamping part.

During the in-service use, can utilize first fixed clamping part and first activity clamping part to grasp the nail, make the nail outwards extract a segment distance, later accomplish pulling out of nail with the fixed clamping part of the second that thickness is thicker, structural strength is higher and the second activity clamping part, can effectively utilize the structural feature of activity chuck and fixed chuck, the nail operation is pulled out in more convenient and fast's completion, simultaneously, extension nail puller life that also can furthest.

The nail pulling device is simple in structure and reasonable in design, the pulleys in the sliding assembly can follow up in the nail pulling process, the supporting arm is guaranteed to keep the auxiliary supporting function all the time, the nail pulling angle cannot be changed, the nail is pulled out completely, secondary utilization can be directly carried out without finishing, the nail pulling operation is simple, force application is easy, the damage to the nail is small, the nail can be effectively recycled, and the nail pulling device is energy-saving and environment-friendly. This nail puller still can act as the hammer temporarily and use when being provided with the tup, can in time revise the nail at pulling out the nail in-process to in the nail pulling operation, the maintenance that also can be better is by the intact of nail.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
