Description

A kind of crow bar nail puller

The utility model relates to a kind of crow bar nail puller technical field.

The nail puller mechanical structure design of using at present is unreasonable, and the sled head is short, sled head-clamp angle little nail nipping strength deficiency, the nail nipping effect is undesirable, has influenced the efficient of nail nipping, and the also unreasonable insufficient strength of handle body Section Design is often crooked easily, whole configuration design is not attractive in appearance yet, and can not work as crow bar and use.

The purpose of this utility model is a kind of crow bar nail puller of design, and it is made up of handle, handle body and sled head, and handle body section is oval, handle body and sled head-clamp angle are between 91 °～135 °, thereby overcome above-mentioned shortcoming, nail nipping has the force efficiency height, and mechanical structure is reasonable in design durable.

The utility model is achieved in that handle 4 connection handle bodies 1, and handle body 1 section is oval, and handle body 1 connects sled 3, has sled mouth 2 on sled 3 top, and handle body 1 is 91 °＜α＜135 ° with prizing a angle between 3.

The utility model has the advantages that: make the practicality of nail puller reasonable in design by Mechanics Calculation, nail nipping has the force efficiency height, durable long service life, and configuration design is attractive in appearance, and can work as the crow bar use by one-object-many-purposes.

Below in conjunction with accompanying drawing, the utility model is described further with embodiment:

Fig. 1 front view, the view of Fig. 2 for making progress at Figure 1B, Fig. 3 is the cutaway view at Figure 1A-A place, the view of Fig. 4 for making progress at Fig. 1 C.

In the accompanying drawing: 1, handle body, 2, the sled mouth, 3, the sled head, 4, handle.

Handle 4 connection handle bodies 1, handle body 1 section are oval, and handle body 1 connects sled 3, has sled mouth 2 on sled 3 top, and handle body 1 is 91 °＜α＜135 ° with prizing a angle between 3; Fix the nail cap with the sled mouth 2 on the sled 3, move handle 4 with hand nail is tripped out from object.
