Detailed Description

The present application is further described below with reference to specific embodiments, and it should be noted that, without conflict, any combination between the embodiments described below or between the technical features may form a new embodiment.

In the description of the present application, it should be noted that, for the terms of orientation, such as "central", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., it indicates that the orientation and positional relationship shown in the drawings are based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be construed as limiting the specific scope of protection of the present application.

It should be noted that the terms "first," "second," and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

One of the preferred embodiments of the present application, as shown in fig. 1 and 20, is a convertible function scraper blade comprising a handle 1, a blade 400 and a change over assembly 2. The front side of handle of a knife 1 is provided with cutting area 101, and the inner chamber 100 of handle of a knife 1 communicates with the front end of handle of a knife 1 and cutting area 101 respectively. The blade 400 is detachably mounted on the front part of the exchanging assembly 2; the exchanging component 2 is installed in the inner cavity 100 and extends to the outer side of the tool holder 1 through the top, so that a user can drive the exchanging component 2 to drive the blade 400 to sequentially slide to the first position, the second position and the third position from back to front along the inner cavity 100. When the blade 400 is in the first position, the rear side of the blade 400 is located within the cutting zone 101, and the blade 400 may then be used to perform the cutting function of the knife. When the blade 400 is located at the second position, the front side of the blade 400 is located outside the front end of the tool holder 1, and the blade 400 can be used for achieving the blade pushing function of the tool. When the blade 400 is in the third position, the blade 400 is completely outside the forward end of the handle 1, allowing the blade 400 to be replaced.

It will be appreciated that when the rear side of the blade 400 is located at the cutting region 101, the combined structure of the blade 400 and the handle 1 is the same as or similar to that of a conventional box opener, so that the cutting function of the conventional box opener can be realized by the blade 400. When the front side of the blade 400 is located outside the front end of the handle 1, the combined structure of the blade 400 and the handle 1 is the same as or similar to that of a conventional shovel blade, so that the blade 400 can be used for realizing the push shovel function of the conventional shovel blade. When the blade 400 is moved completely out of the front end of the handle 1, the blade 400 can be removed for replacement with a new blade 400 due to the detachable connection of the blade 400 and the exchange assembly 2. Therefore, compare the single function of traditional unpacking sword, the diversification of cutter function can be realized to this application to convenience of customers' daily use more.

In this embodiment, as shown in fig. 1 to 3, the cutting region 101 may be disposed on one side of the front portion of the tool shank 1, or may be disposed on both sides of the front portion of the tool shank 1. The specific number of the cutting areas 101 can be selected according to actual needs, and in order to improve the utilization rate of the tool and the symmetrical appearance of the tool, the cutting areas 101 are preferably disposed on two sides of the front portion of the tool shank 1 in this embodiment.

It will be appreciated that when the cutter is in use in the cutting function, the blade 400 cuts through the rear ends in the cutting zone 101; when the blade is in use with a dozing function, the blade 400 is dozing through the front side. Compared with the single-side use of the traditional blade 400, the utilization rate of the blade 400 can be effectively improved. Of course, when one of the functions of cutting or spading is used more, which results in more abrasion on one side of the blade 400, the blade 400 can be turned to continue to be used, so as to further improve the utilization rate of the blade 400.

In the present embodiment, as shown in fig. 1 to 3 and 6 to 9, an inclined abutting surface 115 is provided on the front side of the holder 1. The front side of the knife handle 1 is provided with a claw part 102, the claw part 102 and the attaching surface 115 can form a cutting area 101 by mutually matching, and the opening direction of the cutting area 101 is inclined with the extending direction of the knife handle 1. An included angle between the opening direction of the cutting area 101 and the extension direction of the tool shank 1 can be set to be alpha, and the included angle alpha is set to be 30-60 degrees.

It should be noted that, as shown in fig. 3, when the cutting tool uses a cutting function, an included angle gap is inevitably formed between the tool shank 1 and the piece 500 to be cut due to the holding of the tool shank 1 by the palm; the included angle gap is the included angle alpha. In order to avoid the contact between the finger and the piece to be cut 500 when the piece to be cut 500 is cut, the included angle alpha is at least 30 degrees; however, the excessively large included angle α is also inconvenient for the operation of the tool holder 1, so that the included angle α is generally 60 ° to 70 ° at the maximum, and preferably 60 °.

Specifically, as shown in fig. 6 to 9 and 11, the tool holder 1 includes an upper housing 11 and a lower housing 12. The two sides of the front parts of the upper shell 11 and the lower shell 12 are both provided with binding surfaces 115; so that the abutting surfaces 115 of the corresponding sides of the upper and lower cases 11 and 12 are aligned with each other when the upper and lower cases 11 and 12 are combined with each other. Meanwhile, the two sides of the front part of the upper shell 11 are both provided with first angle plates 114 spaced from the attachment surface 115, and the two sides of the front part of the lower shell 12 are both provided with second angle plates 121 spaced from the attachment surface 115; so that the first and second corner plates 114 and 121 of the corresponding sides can be combined with each other to form the sheepfold 102 when the upper and lower cases 11 and 12 are combined with each other.

It should be appreciated that the horn 102 has a sharp corner to facilitate the knife piercing the work piece 500 through the sharp corner of the horn 102 when cutting the work piece 500. The sheepsfoot portion 102 may then position the work piece 500 during cutting by the blade 400 to avoid the work piece 500 becoming detached from the knife during cutting.

In this embodiment, as shown in fig. 4, 7 and 11, the upper end and/or the lower end of the abutting surface 115 is provided with a chamfered surface 116, and the chamfered surface 116 is arranged obliquely, so that when the blade 400 is cutting the member to be cut 500, the blade 400 can perform oblique cutting. When the blade 400 cuts, an included angle between the blade 400 and the workpiece 500 to be cut can be set to be beta, and the included angle beta is 30-90 degrees.

It can be understood that, as shown in fig. 3, since the abutting surface 115 is a plane, when the cutter performs cutting, the abutting surface 115 is generally kept in parallel with the member 500 to be cut, and such a posture is a tangential cutting, so that resistance can be reduced to ensure smooth cutting. In the actual use process, in order to adapt to the use habits of users and deal with more use scenes, a cutter is often required to perform oblique cutting. Therefore, as shown in fig. 4, in order to ensure that the cutter can perform the oblique cutting, the end portions of the abutting surfaces 115 on both sides of the front portion of the upper housing 11 and/or the lower housing 12 may be provided with inclined chamfered surfaces 116. Wherein, the included angle between the chamfer surface 116 and the binding surface 115 is 90-beta; and when the included angle beta is 90 degrees, the cutter can only perform positive cutting.

It should be appreciated that the piece 500 to be cut may be a common piece of cardboard or other item that needs to be cut in everyday life.

In this embodiment, as shown in fig. 5, 6, 8, 11 and 12, the knife handle 1 includes a housing and a flexible anti-slip strip 13. The left side and the right side of the shell are both provided with clamping grooves 113; the antislip strip 13 has two, and the antislip strip 13 can slide the block with the draw-in groove 113 of the corresponding side of casing to when holding handle 1, can improve the comfort of holding through the antislip strip 13, can also increase the non-skid property of handle of a knife 1 simultaneously. Can carry on spacingly through limit structure between antislip strip 13 and the draw-in groove 113 to avoid cutting or pushing away the in-process of shovel because too big cause antislip strip 13 and casing to take place to break away from hard.

Specifically, as shown in fig. 5, 6, 8, 11 and 12, the housing includes an upper housing 11 and a lower housing 12; the two sides of the upper end surface of the upper shell 11 and the two sides of the lower end surface of the lower shell 12 are both provided with a clamping groove 113. So that the card slots 113 of the corresponding sides of the upper and lower cases 11 and 12 can be symmetrical to each other when the upper and lower cases 11 and 12 are combined with each other. The section of the anti-skid strip 13 is shaped like U, and the two sides of the anti-skid strip 13 are provided with vertically extending clamping parts 131; therefore, when the antislip strip 13 is installed on the housing, the antislip strip 13 can cover the two sides of the upper housing 11 and the lower housing 12, and the antislip strip 13 can be slidably engaged with the engaging grooves 113 symmetrically arranged on the two sides of the housing through the engaging portion 131.

In this embodiment, as shown in fig. 8, 11 and 12, the limiting structure includes a limiting groove 1130 and a limiting block 132; the limiting groove 1130 is disposed at the rear portion of the engaging groove 113, and the limiting block 132 is disposed at the rear portion corresponding to the engaging portion 131. Therefore, in the process that the anti-slip strips 13 are installed on the two sides of the shell, the anti-slip strips 13 can be limited by the limiting blocks 132 and the limiting grooves 1130 in a clamping mode.

It can be understood that the specific number of the limiting grooves 1130 and the limiting blocks 132 can be set according to actual requirements, for example, as shown in fig. 8 and 12, the number of the limiting grooves 1130 is two, and the number of the limiting blocks 132 is two correspondingly.

For the sake of understanding, the specific installation process of the cleats 13 is as follows: the upper housing 11 and the lower housing 12 are mutually combined and fixed by a fastener to form a complete housing, and a pair of symmetrical slots 113 are formed on the left side and the right side of the housing. Subsequently, the front end of one anti-slip strip 13 is aligned with one side of the rear end of the housing, and the anti-slip strip 13 is pushed to slide along the clamping groove 113 on the corresponding side of the housing through the clamping part 131 until the front end of the anti-slip strip 13 abuts against the front end of the clamping groove 113; at this time, the stopper 132 at the rear of the engaging portion 131 can be engaged with the stopper 1130 at the rear of the engaging groove 113. The process is then repeated with the other cleat 13 attached to the other side of the housing.

In one embodiment of the present application, as shown in fig. 1, 2, 5, 6, and 13 to 15, a first through groove 111 communicating with the inner cavity 100 is provided on an upper side of the tool holder 1. The exchanging assembly 2 comprises a regulating block 23 and a supporting plate 21; the supporting plate 21 is slidably mounted in the inner cavity 100, and the blade 400 is detachably mounted on the mounting part 211 at the front part of the supporting plate 21; the adjusting block 23 is elastically mounted on the supporting plate 21 and extends into the first through groove 111. When the blade 400 is located at a specific position, the adjusting block 23 and the tool holder 1 can be locked by a locking structure. When the position of the blade 400 needs to be changed, the locking structure can be unlocked by operating the adjusting block 23, and the supporting plate 21 is driven to drive the blade 400 to move.

It will be appreciated that the particular positions of the blade 400 correspond to the position described above for performing the cutting function, the blade function, and the replacement of the blade 400.

In this embodiment, as shown in fig. 13 and 14, the supporting plate 21 is provided with a positioning groove 212 having an upward opening; the conditioning block 23 may be slidably mounted within the positioning slot 212. And, cooperate through the elastic component between the bottom of regulating block 23 lower extreme and the bottom of constant head tank 212, and then realize unblock the locking structure through pressing regulating block 23 downwards in order to impel its slip along constant head tank 212.

It is understood that the specific structure of the elastic member is well known to those skilled in the art, and the common elastic member may be a spring or an elastic sheet.

It can be further understood that, when designing the positioning groove 212, in order to ensure the smooth sliding of the adjusting block 23, the size of the positioning groove 212 needs to be slightly larger than that of the adjusting block 23, so that a certain shaking space exists after the adjusting block 23 is installed in the positioning groove 212. Also, when the upper side of the cutter is directed downward, the regulating block 23 may fall from the first through groove 111.

In order to ensure the installation stability of the adjusting block 23, as shown in fig. 13 and 14, the supporting plate 21 is provided with a through positioning hole 2120 at the bottom of the positioning groove 212, and the lower end of the adjusting block 23 is provided with a positioning rod 232. The size of the end of the positioning rod 232 is larger than that of the positioning hole 2120 in a normal state, and the end of the positioning rod 232 is retractable; during the installation of the adjusting block 23, the end of the positioning rod 232 can be retracted to pass through the positioning hole 2120. So that the adjusting block 23 can slide along the positioning hole 2120 by the positioning rod 232 during pressing the adjusting block 23.

It will be appreciated that, when the positioning rod 232 is disposed at the lower portion of the adjusting block 23, the elastic member is preferably a spring, and the spring may be labeled as the first spring 22, in order to facilitate the disposition of the elastic member between the adjusting block 23 and the bottom of the positioning groove 212. The first spring 22 may be sleeved on the positioning rod 232.

In this embodiment, as shown in fig. 6, the first through groove 111 is disposed in the upper housing 11; the extending direction of the first through groove 111 is parallel to the length direction of the tool holder 1. The adjusting block 23 can slide along the extending direction of the first through slot 111 to drive the supporting plate 21 to move the blade 400 to a specific position. Further, in order to facilitate the locking of the blade 400 by the locking structure, the locking structure may be provided at a side portion of the first through groove 111 in the extending direction.

Specifically, the locking structure includes a locking groove and a latch 231; the specific arrangement of the locking groove and the latch 231 can be various, including but not limited to the following two types:

the setting method is as follows: as shown in fig. 9, 10, 13 and 14, the number of the locking grooves is at least two, and the locking grooves are arranged at intervals along at least one side of the extending direction of the first through groove 111; the fixture block 231 is arranged at the corresponding side of the adjusting block 23; so that the locking of the blade 400 at the specific position is achieved by the engagement of the latch 231 with the locking groove at the specific position; the locking block 231 is driven to be separated from the corresponding locking groove by pressing the adjusting block 23, so as to release the locking of the blade 400 at the specific position.

The setting mode is two: the number of the fixture blocks 231 is at least two, and the fixture blocks are arranged at intervals along at least one side of the extending direction of the first through groove 111; the locking grooves are arranged on the corresponding sides of the adjusting blocks 23; so that the locking of the blade 400 at the specific position is achieved by the engagement of the locking groove with the latch 231 at the specific position; the locking groove is driven to be separated from the corresponding latch 231 by pressing the adjusting block 23, so as to unlock the blade 400 at a specific position.

It is to be understood that, for the convenience of the following description, the specific arrangement of the locking groove and the latch 231 is exemplified by the first arrangement described above.

It will also be appreciated that the knife in this embodiment includes at least three functions, cutting, spading and replacing the blade 400. Wherein, when cutting and shoveling, the blade 400 needs to be locked due to the stress; therefore, the number of the locking grooves is at least two, so that when the blade 400 performs cutting and shoveling, the locking of the blade 400 is realized by the engagement of the corresponding locking groove and the fixture block 231.

Of course, in order to ensure that the blade 400 can be replaced at any angle, the locking structure may be used to lock the blade 400 when the blade 400 is replaced. Namely, the number of the locking grooves is at least three, and the three locking grooves are arranged at intervals.
