Description

Claw hammer

Technical Field

The utility model belongs to the technical field of hardware and tools and specifically relates to a claw hammer.

Background

At present, the claw hammer that people used includes the hammer handle, and hammer handle one end is provided with the claw hammer head, and the top of claw hammer head is provided with the support column, sets up the support column in order to increase the claw height, and the iron nail that makes need extract can be extracted completely, and the support column of current claw hammer all is the snap-on together with the claw hammer head, and can not dismantle, consequently, current claw hammer in case the preparation is accomplished the back, and the length of support column just can not change. The claw hammer with the structure has the following problems in the use process: because the specification of iron nail is various, the length difference is great, to the iron nail of different length, the length of support column should suit with the length of iron nail just can guarantee that the nail nipping effect is best, if the length of support column is too short for the iron nail, then the pulling force direction that acts on the iron nail at the nail nipping in-process is along with the iron nail pulled out can be very fast skew iron nail axial direction and skew degree more and more big, draw the iron nail to buckle very easily like this, and then cause the damage and can't reuse to the iron nail, it is extravagant more serious, if the length of support column is for the iron nail overlength, then need apply bigger power at the nail nipping in-process and just can extract the iron nail, waste time and difficultly.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a nail nipping hammer is provided at the in-process assurance iron that plays to order and surely not receive any damage and can adapt to various length iron nails.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a claw hammer includes tup subassembly, handle, the one end of tup subassembly is provided with the claw wing, and the other end is provided with the tup, the tup subassembly is fixed on hand, still includes supporting part and adjustment mechanism, adjustment mechanism's one end and supporting part fixed connection, the inside through hole that is equipped with of handle, the one end that the handle was kept away from to the tup subassembly is equipped with the through-hole, the through-hole link up mutually with handle inside, adjustment mechanism run through whole handle and with tup subassembly and handle swing joint through the through-hole.

Further, the adjusting mechanism is an adjusting screw with an external thread.

Furthermore, the adjusting screw rod is connected with the hammer head component through threads.

Further, the adjusting screw rod is connected with the handle through threads.

Furthermore, the hammer head component is provided with an internal thread through hole matched with the external thread adjusting screw rod for use, and is connected with the hammer head component through threads.

Furthermore, the inside internal thread hole that cooperatees and use with the adjusting screw who has the external screw thread that is equipped with of handle, adjusting screw runs through the tup subassembly and with handle threaded connection.

Furthermore, one end of the adjusting screw rod, which is far away from the hammer head component, is provided with an adjusting button.

Further, the length of the adjusting screw is greater than that of the handle.

The utility model has the advantages that: through being provided with adjusting screw on the tup subassembly, during the use, can upwards rotate adjusting screw through rotatory adjustment button and make the supporting part outwards stretch out certain distance to extract the iron nail of different length, do not harm the effect of iron nail when reaching the nail nipping.

Drawings

The present invention will be further explained with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Fig. 2 is a schematic structural diagram of an embodiment of the present invention.

Figure 3 is the utility model discloses adjusting screw structure sketch map.

In the figure, a supporting part 1, a hammer head component 2, a nail pulling wing 2-1, a hammer head 2-2, a handle 3, an adjusting screw rod 4 and an adjusting button 5 are arranged.

Detailed Description

The following provides a further description of a claw hammer according to the present invention with reference to the following embodiments.

Fig. 1 shows an embodiment of the present invention, and an adjusting screw 4 is provided on the hammer head assembly 2 of the claw hammer, and the height of the claw point can be adjusted by using the adjusting screw 4 as an adjusting mechanism. The specific structure of the claw hammer is as follows: a through hole is arranged inside the handle 3, one end of the hammer head component 2 is fixedly connected with the handle 3, and the other end of the hammer head component is provided with a through hole communicated with the handle 3. The downthehole internal thread that is equipped with on adjusting screw 4 with through-hole matched with external screw thread, adjusting screw 4 and tup subassembly 2 carry out threaded connection and run through whole handle.

As shown in fig. 3, one end of the adjusting screw 4 is provided with the supporting portion 1, and the adjusting screw 4 is fixedly connected with the supporting portion 1, and may also be connected by a known connection method such as a screw connection or a snap connection. The other end of the adjusting screw rod 4 is provided with an adjusting button 5 which is fixedly connected, and the adjusting screw rod 4 is rotated by the adjusting button 5 to move up and down in the through hole of the internal thread of the hammer head component 2.

The support part 1 may be in various shapes such as a hemisphere, and is preferably plate-shaped and has arc-shaped support surfaces at both ends, which increases the contact area of the fulcrum and also increases the stability of nail pulling.

When the nail puller is used, the length of the adjusting screw rod 4 can be controlled through the adjusting button 5, the supporting part 1 extends out for a certain distance, nails with various lengths can be easily pulled out, the application range is wide, the adjusting button 5 is rotated to enable the supporting part 1 and the hammer head component 2 to lean against each other when the nail puller is not used, and the nail puller has almost the same appearance as a common nail puller.

Adjusting screw 4 and tup subassembly 2's connected mode also can be known technical mode such as buckle formula, snap ring formula or fixed pin, and is preferred, uses the utility model discloses a threaded connection mode is comparatively convenient like this and comparatively accurate when adjusting supporting part 1 height.

The utility model discloses a another kind of embodiment, like fig. 2, adjusting screw 4's threaded connection position can also be put inside handle 3, and handle 3's inside is equipped with has the internal screw thread through-hole, is equipped with the through hole on the tup subassembly 2, and adjusting screw 4 carries out threaded connection through the through hole of tup subassembly 2 and handle 3. When the nail puller is used, the length of the adjusting screw rod 4 can be controlled through the adjusting button 5, so that the supporting part 1 extends out for a certain distance, and nails with various lengths can be easily pulled out. Because the length of the connecting part of the adjusting screw rod 4 and the handle 3 is longer, the stability of the adjusting screw rod 4 is increased, so that the supporting part is taken as a stable and powerful fulcrum when the iron nail is pulled out.

The utility model discloses claw hammer, its adjusting screw 4's length is greater than handle 3's length, and is comparatively convenient when rotating through adjustment button 5 like this.

The above embodiments are merely illustrative of the present invention and are not intended to limit the scope of the present invention. The protection scope of the present invention can not be limited thereby, and all equivalent changes or modifications made according to the present invention without substantial changes should be covered within the protection scope of the present invention.
