Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

As shown in fig. 1 and 2, the putty knife comprises a blade 2 for scraping a working surface and a handle 1 connected to the rear end of the blade, wherein a strip-shaped groove 11 is arranged on the right side of the handle, a functional component 3 for mounting and dismounting a screw is arranged in the groove, the functional component comprises a body 31 suitable for being pinched by hands and a functional part arranged on the body, and therefore the functional component is a portable small tool.

Preferably, the functional part may be the head 32 of a screwdriver for turning the screw, thereby making the functional part a portable small screwdriver.

When the screw needs to be assembled and disassembled, an operator can take out the functional component with the screwdriver bit from the groove of the handle, and the screwdriver bit can be used for assembling and disassembling the screw by pinching the body. In order to facilitate the taking and placing of the functional components, a semicircular notch can be formed in the opening of the groove. When the functional component is placed in the groove, the functional component can be partially moved out of the groove and the notch, so that the functional component can be conveniently pinched from the notch and moved outwards.

It will be appreciated that the functional part may also be a regular hexagonal wrench for turning a socket head cap screw, or even a paper cutting blade or the like.

As a preferable scheme, as shown in fig. 3, the body can be made into a square sheet which is formed by punching, and the batch heads are respectively arranged at the middle positions of 4 edges of the body. Of course, the screwdriver bits can comprise a linear screwdriver bit with two specifications of large and small sizes and a cross screwdriver bit with two specifications of large and small sizes, so that the screwdriver bits are suitable for assembling and disassembling screws with various models and specifications. The linear head and the body can be punched and formed together, and the cross head and the body can be welded, so that a functional component with an integral structure is formed.

It is known that for the functional component with a screwdriver bit, the body thereof functions like a handle on a screwdriver bit and mainly bears torque during operation, so that the thickness of the flat body can be reduced as much as possible, the functional component can be conveniently arranged in the groove of the handle, and the width of the body can be correspondingly increased, so that sufficient torque can be conveniently formed during screw assembly and disassembly.

In order to facilitate the taking and placing of the functional components, a magnetic suction block 12 can be arranged on one side in the groove, and correspondingly, the body is made of a ferromagnetic material. When the functional unit is put into the groove of the handle, the magnetic suction block can adsorb the body, so that the functional unit is reliably positioned in the groove, the functional unit is prevented from being separated from the groove, and the functional unit is conveniently taken out from the groove.

As another preferable mode, as shown in fig. 4, the body of the functional component includes a long connecting section 311 and a short connecting section 312, so that the functional component is formed in an L-shape like an allen key formed by connecting the long connecting section and the short connecting section, and a bit is provided at each end of the long connecting section and the short connecting section of the body. When the screw on the surface of the workpiece needs to be disassembled and assembled, the screwdriver head at the end part of the short connecting section can be connected with the screw head, and then the long connecting section is rotated to generate larger torque, so that the screw is convenient to disassemble and assemble. When the screw in the deeper dent needs to be assembled and disassembled, the long connecting section can extend into the dent, the screwdriver head at the end part of the long connecting section is connected with the screw head, and the screw can be conveniently assembled and disassembled by rotating the short connecting section.

It can be understood that, because the torque generated when the long connecting section is rotated is larger than the torque generated when the short connecting section is rotated, the batch head specification connected to the end part of the long connecting section can be smaller than the batch head specification arranged at the end part of the short connecting section, thereby being beneficial to the assembly and disassembly of screws with different specifications, and avoiding the damage of the screws or the slippage between the batch head and the screw head caused by the overlarge torque.

It should be noted that the body can be made into other shapes such as equilateral triangle, circular lamp, and the bits are respectively arranged on each side of the body, or the bits are arranged on the edge of the body at equal intervals.

In order to accommodate the scraping of different work surfaces, the blade comprises a straight flat scraper 21 at the front end and a circular arc-shaped notch scraper 22 at the left side of the blade.

Preferably, the notch scraper is arranged to be as close as possible to the front end of the blade, and on the one hand, the notch scraper is arranged to be as far away from the handle, so that hands of workers are prevented from being scratched and injured. On the other hand, the front side of the notch scraper is connected with the flat scraper, and the cutting edge of the front side of the notch scraper is connected with the left side of the cutting edge of the flat scraper at the moment, so that a sharp slotting cutting edge 23 is formed. The slotting blade can be used for the operation requirements of slotting of the carton packaging tape and the like, when the packaging tape on the carton needs to be opened, the handle can be held by hand, the slotting blade is aligned to the carton sealing tape at the left and right splicing positions of the carton cover, then the handle is moved backwards, and the slotting blade can easily cut the packaging tape on the carton.

Further, a semicircular roller scraping opening 24 can be arranged at the right side edge of the blade. It should be noted that the notch scraper on the left side is provided with a cutting edge, while the roller scraper on the right side is not provided with a cutting edge. When indoor decoration, need with cylinder coating paint on the wall etc. when we finish the coating operation of going on the wall with the cylinder, need will adsorb the coating sanitization in the cylinder to the used repeatedly of cylinder can scrape the mouth with semicircular cylinder and place the columniform cylinder surface one end that the coating paint used this moment, then along axial displacement putty knife, can conveniently extrude the residual coating that adsorbs on the cylinder, thereby makes things convenient for the washing of cylinder. Of course, the scraping edge of the roller can be made as close as possible to the end of the blade, so that on the one hand, the residual paint squeezed from the roller can be prevented from contaminating the hands of the operator, and on the other hand, a sheet-like projection 25 capable of opening the paint can is formed between the front side of the scraping edge of the roller and the right side of the flat scraper. When the tight-fit cover of the paint can needs to be opened, the sheet-shaped protrusion can be inserted into a gap between the cover and the can body of the paint can, and then the tight-fit cover of the paint can be pried open by pulling the handle.

Furthermore, two wrenching openings 26 capable of clamping nuts can be arranged in parallel in the front and at the back of the left side edge of the blade behind the notch scraper, each wrenching opening comprises a front parallel side edge, a back parallel side edge and a V-shaped bottom edge connected between the front side edge and the back side edge, and the included angle of the V-shaped bottom edges is 120 degrees, so that the wrenching openings can be matched with heads of corresponding hexagon nuts or hexagon screw heads, and the nuts or the screws can be conveniently rotated. Of course, the sizes of the front and the rear wrenching openings can be matched with nuts with different specifications so as to adapt to the assembly and disassembly of the nuts or the screws with different specifications.

In order to facilitate the removal of a small number of nails during decoration operation, a nail pulling hole 27 can be further arranged in the middle of the front portion of the blade, as shown in fig. 5, the nail pulling hole comprises a large hole 272 with a circular shape at the rear side, a small hole 271 with a circular shape at the front side, and a trapezoidal transition hole 273 connected between the large hole and the small hole, and the left side and the right side of the transition hole are respectively tangent to the same side of the large hole and the small hole, so that the nail pulling hole is in a water drop shape with a small front part and a large rear part. When the nail needs to be pulled out, the large hole of the nail pulling hole can be sleeved on the round head of the nail, the round head of the nail extends out of the large hole, then the putty knife is moved backwards, the nail rod of the nail is moved towards one side of the small hole and clamped at the transition hole, and the round head of the nail is attached to the upper surface of the blade at the moment. Then the handle is pulled upwards, so that the nail can be pulled upwards. Because the big holes are connected with the small holes through the trapezoidal transition holes, the nail rods of the nails with different specifications can be clamped at different positions of the transition holes, so that the nail puller is suitable for pulling out the nails with different specifications. Of course, we can increase the diameter of the large hole appropriately to ensure that the head of the nail can pass through the large hole.

Finally, it is also possible to provide the handle at its rear end remote from the blade with a raised rectangular projection which constitutes the striking member 13. When the close-fitting cover such as a paint can needs to be sealed again in decoration operation, the cover can be covered on the opening of the can body firstly, then the handle is held by hands, the knocking part is aligned to the edge of the cover, the knocking part is used for knocking the edge of the cover downwards, the cover can be sealed again, and the curing of paint is avoided. It will be appreciated that the handle is typically made of a material such as plastic and accordingly the striking member may be formed integrally with the handle for ease of manufacture. Alternatively, the striking member may be made of a material such as steel so as to have high hardness, thereby being used for striking a projection such as a nail.

Finally, an opening notch 28 for opening a small-bore bottle cap like a beer bottle can be arranged on the right side of the blade at the rear side of the scraping opening of the roller, so that the small-bore tight-fit cap can be conveniently opened.
