In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

Furthermore, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Referring to fig. 1 to 9, an embodiment of the present invention provides an assembled utility knife, which includes a knife holder 100, a sliding assembly 200 capable of sliding in a longitudinal direction in the knife holder 100, and a blade 300 connected to the sliding assembly 200 and capable of extending and retracting in and out along with the sliding assembly.

The handle 100 is a unitary, removable structure that facilitates removal and replacement or repair of internal components. Specifically, the hilt 100 includes a first splicing member 101 and a second splicing member 102 which have the same structure and are symmetrically arranged with respect to each other, the cross sections of the first splicing member and the second splicing member are both in a groove shape, when the notches of the first splicing member and the second splicing member are opposite to each other and spliced, a splicing body T for holding can be formed through detachable connection with each other, and a first end cap 103 and a second end cap 104 are detachably connected with the head end and the tail end of the splicing body T respectively. In the invention, the head end of the splice body T is one end corresponding to the outlet of the blade 300, and the tail end of the splice body T is the opposite other end. The first end cap 103 and the second end cap 104 can be respectively fixed at the head and tail ends of the splice body T in a snap-fit connection manner. The first splicing member 101 and the second splicing member 102 are both provided with sliding paths 105 which correspond to each other and are transversely through, and a plurality of positioning grooves 106 with the same specification are equidistantly arranged on one side of each sliding path 105.

The sliding assembly 200 includes a sliding piece 201 disposed inside the splicing body T and capable of sliding relatively along the longitudinal direction of the splicing body T, and the sliding assembly 200 further includes a positioning element 202 having one end rotatably connected to the sliding piece 201 and the other end capable of forming a fit with any one of the positioning grooves 106 by rotation.

The blade 300 of the present invention may be an existing utility knife blade, one end of which is detachably fixed to the sliding blade 201, and the other end of which can extend out of the first end cap 103, and the first end cap 103 is provided with a knife outlet 103a for allowing the blade 300 to pass through. The initial positioning of the blade 300 can be achieved after the positioning member 202 is inserted into a positioning slot 106 according to actual requirements.

The present invention can set: the direction of the side of the sliding path 105 close to the positioning groove 106 is the same as the direction of the knife edge, and the direction of the side of the sliding path 105 far from the positioning groove 106 is the same as the direction of the knife back.

Further, the first splicing member 101 comprises a first strip 101a, and a pair of first splicing outer edges 101a extending along the longitudinal direction and symmetrically arranged at two side edges of the first strip 101a, so that the first splicing member 101 is integrally formed into a groove shape. Similarly, the second splicing member 102 comprises a second strip 102a and second splicing outer edges 102a extending along the longitudinal direction and symmetrically arranged at two side edges of the second strip 102 a.

The edge of the first inserting outer edge 101a is provided with a first hook 101a-1 extending longitudinally and a first inserting groove 101a-2 positioned at the inner side of the first hook 101 a-1. Similarly, the edge of the second inserting outer edge 102a is provided with a corresponding second hook 102a-1 and a second slot 102a-2 located at the inner side of the second hook 102 a-1; the first hook 101a-1 and the first slot 101a-2 form central symmetry with the second hook 102a-1 and the second slot 102a-2, respectively. In the present invention, the first hook 101a-1 can be inserted into the second slot 102a-2, and the second hook 102a-1 can be inserted into the first slot 101a-2, so that the first splicing member 101 and the second splicing member 102 can be spliced (detachably connected).

Preferably, the inner hook surfaces G of the first hook 101a-1 and the second hook 102a-1 form an inclined slope, so that the width of the slot openings of the first slot 101a-2 and the second slot 102a-2 is smaller than the width of the slot bottom. Therefore, when the first hook body 101a-1 is inserted into the second slot 102a-2, the first hook body 101a-1 cannot be transversely separated from the second slot 102a-2 due to the slope of the inner hook surface G; similarly, the second hook 102a-1 cannot be laterally separated from the first slot 101a-2 when inserted into the first slot 101 a-2.

Further, a strip-shaped magnetic member (not shown) extending longitudinally is fixed on the inner side wall of the splice body T corresponding to one side of the positioning slot 106. The bar-shaped magnetic member may be a bar-shaped magnet. In addition, the positioning member 202 includes a first connector 202a rotatably connected to the sliding piece 201, a second connector 202b capable of rotating forward and backward around a rotation center of the first connector 202a inside the splicing body T, and a locking block 202c detachably fixed to the second connector 202b and capable of magnetically attracting the bar-shaped magnetic member. The locking block 202c is preferably a hollow iron cylinder whose cross-section fits within the bottom profile of the detent 106. Therefore, under the magnetic attraction of the bar-shaped magnetic member, the locking piece 202c can be attracted and inserted into any one of the positioning grooves 106, resulting in the primary positioning. Preferably, the bottom of the positioning slot 106 is contoured to match the arc of the locking block 202 c. The locking block 202c and the second connector 202b of the present invention can be detachable by using threads (the second connector 202b has a transverse screw hole, and the outer side wall of the locking block 202c has a corresponding external thread) or directly fixed by inserting (the second connector 202b has a transverse insertion hole, and the locking block 202c is directly inserted into the insertion hole, and is only kept stable by friction).

Further, one side of the positioning groove 106 corresponding to the tail end direction of the splice T is a first surface 106a, and the first surface 106a is perpendicular to the longitudinal direction of the sliding path 105. One side of the positioning groove 106 corresponding to the head end direction of the splice body T is a second surface 106b, and the second surface 106b is an arc curved surface protruding outward. Preferably, the junction between the bottom of the positioning slot 106 and the second surface 106b can be tangent smoothly, which ensures the smoothness of the sliding of the locking block 202c in the sliding path 105.

Further, the sliding assembly 200 further includes an elastic piece 203 having one end fixed to the sliding piece 201, and the other end of the elastic piece 203 has a hook 203 a. The elastic piece 203 has elastic deformation, and is preferably a steel piece having toughness. The first connector 202a is provided with a slot 202a-1 corresponding to the hook 203a, and when the second connector 202b is rotated to be separated from the positioning slot 106 and the locking block 202c is higher than the top of the first surface 106a, the hook 203a can be inserted into and fixed in the slot 202 a-1.

The sliding path 105 includes a positioning section 105a corresponding to the positioning groove 106, a locking start section 105b located at one end of the positioning section 105a and corresponding to the tail end of the splice body T, and a locking release section 105c located at the other end of the positioning section 105a and corresponding to the head end of the splice body T, which are connected to each other. Wherein, the width of the locking starting section 105b is smaller than that of the positioning section 105a, and a first extrusion slope 105b-1 is arranged on one side (the direction of the knife back) of the locking starting section 105b far away from the positioning groove 106; the unlocking section 105c has a width smaller than that of the positioning section 105a, and a second pressing slope 105c-1 is provided on the unlocking section 105c on a side (blade direction) close to the positioning groove 106. One end of the unlocking section 105c corresponding to the head end direction of the splice body T is also provided with a mutually communicated sliding seam 105d, and the sliding seam 105d extends longitudinally and has a width smaller than that of the unlocking section 105 c.

The invention sets the following steps: when the locking block 202c slides to the unlocking section 105c, the hook 203a of the elastic piece 203 can be inserted into the slot 202a-1, so that the locking block 202c is higher than each positioning slot 106, and the sliding assembly 200 can slide in the sliding path 105 without hindrance.

In the use process of the assembled utility knife, the initial state is set as the accommodating state of the blade 300.

As shown in fig. 9, in the initial state, the lock block 202c is located in the area of the lock start section 105 b.

When the assembled utility knife needs to be used, the blade 300 is pushed out, and the positioning member 202 moves to the area of the positioning section 105 a; due to the magnetic attraction of the bar-shaped magnetic member, the locking piece 202c can be attracted to be inserted into the nearest positioning groove 106, and thus the primary positioning is realized.

When the blade 300 continues to slide outwards, the locking block 202c can touch the second extrusion slope 105c-1, and due to the slope lifting, the locking block 202c can be lifted to a higher height until the hook 203a on the elastic piece 203 is embedded into the clamping groove 202 a-1; at this time, the locking block 202c can be raised above each positioning groove 106 and kept in a stable state, and even if the slide module 200 moves in the reverse direction to the region of the positioning section 105a, the locking block 202c cannot be fitted into the positioning groove 106 in the reverse direction due to the locking of the hook 203a, and therefore, in this state, the slide module 200 and the blade 300 can slide arbitrarily in the region of the positioning section 105a and the unlocking section 105 c.

When the blade 300 is moved backward and reversely, the sliding assembly 200 and the blade 300 can slide across the middle positioning section 105a without hindrance until the locking block 202c touches the first pressing slope 105 b-1; due to the extrusion of the slope, the sinking first extrusion slope 105b-1 can gradually extrude the locking block 202c, and the elastic piece 203 is caused to disengage from the hook groove 202a-1 due to the elastic deformation of the elastic piece 203, and finally the locking block 202c is disengaged from the lock and slides into the area of the locking starting section 105b to return to the initial state.

Further, the elastic sheet 203 of the present invention is preferably configured as follows:

the elastic piece 203 comprises a straight plate area 203b, limiting fixing plates 203c symmetrically arranged on two sides of the center of the straight plate area 203b, and a hook 203a and a replacement hook 203d respectively fixed at two ends of the straight plate area 203b, wherein the hook 203a and the replacement hook 203d form central symmetry about the center of the straight plate area 203 b. The limit fixing plate 203c divides the straight plate region 203b into two insertion parts. Meanwhile, the sliding sheet 201 is also provided with an inserting position 201c for fixing the elastic sheet 203, the inserting position 201c is provided with a slot 201c-1 which extends longitudinally and is through at two ends, and the width of the slot 201c-1 is matched with the thickness of the straight plate area 203 b. Therefore, the two insertion parts of the straight plate region 203b can be inserted into the slot 201c-1, so that the detachable fixation is realized. When the hook 203a is irreversibly deformed or damaged due to long-term use, the elastic piece 203 may be reversely fixed so that the replacement hook 203d faces outward. Preferably, the overall contour of the outer edge of the insertion position 201c is circular, and the outer diameter of the outer edge corresponds to the length of the insertion part, so that the matching limitation and the structural stability of the elastic piece 203 are facilitated.

Further, to facilitate controlling the longitudinal sliding movement of the sliding assembly 200 and the blade 300, the sliding assembly 200 further includes a driving member 204. The driving member 204 comprises a column 204a fixed on the sliding sheet 201 and extending out of the sliding path 105, and a pushing block 204b fixed on the outer end of the column 204 a; it should be noted that: the width of the post 204a is not greater than the width of the sliding slot 105d, and the width of the sliding slot 105d is smaller than the cross-sectional dimension of the locking block 202c, so that the locking block 202c cannot slide into the sliding slot 105d when sliding to the unlocking section 105c, but the post 204a can slide into the sliding slot 105 d.

Further, the first strip 101a and the second strip 102a are provided with sliding paths 105 facing each other. The invention sets the following steps: the sliding piece 201 and the driving piece 204 fixed on the sliding piece form a sliding module together, the sliding module is provided with two types of structures which are symmetrically arranged, different sliding modules can be assembled according to the use habits of the left hand and the right hand of a user, and the pushing block 204b can be installed on any side of the splicing body T according to the requirements and is flexible and changeable.

Further, the thickness of the second connector 202b is matched with the inner side distance between the two side walls of the splicing body T; the transverse length of the locking block 202c is greater than the inside distance between the two side walls of the splice T. It is thus ensured that the second connector 202b can rotate freely inside the splice T, while the locking piece 202c can only move within the sliding path 105.

Further, the two sides of the sliding piece 201 are symmetrically provided with guide strips 201a, and the width of the guide strips 201a corresponds to the inner side distance between the two side walls of the splicing body T (i.e. the distance between the inner side walls of the first splicing member 101 and the second splicing member 102), so that the sliding piece 201 can longitudinally slide inside the splicing body T, and the stability of the sliding piece 201 during sliding can be improved.

Further, the assembled utility knife of the present invention further comprises a telescopic fixing assembly 400, and the blade 300 is connected to the sliding plate 201 through the telescopic fixing assembly 400. The arrangement of the telescopic fixture assembly 400 enables the blade 300 to maintain a stable state during use without internal and external movement.

Specifically, the telescopic fixing assembly 400 includes a knife clamp 401 for fixing the blade 300, four sets of links 402 connected to the periphery of the knife clamp 401, and damping blocks 403 respectively fixed to the ends of the respective links 402. The guide bar 201a is provided with a window 201a-1 corresponding to the damping block 403, and the damping block 403 can extend out of the window 201a-1 under the extrusion of the corresponding connecting rod 402 to extrude the inner side wall of the splice body T (i.e. the inner side wall after the first splicing outer edge 101a and the second splicing outer edge 102a are butted). Preferably, four sets of connecting rods 402 are symmetrically distributed, and four damping blocks 403 are distributed in the shape of four corner points of a rectangle.

In addition, the sliding sheet 201 is provided with a micro-motion groove 201b corresponding to the knife clamping piece 401, and the knife clamping piece 401 passes through the micro-motion groove 201 b; the blade 300 is removably attached to the holder blade 401. The micro-groove 201b is a longitudinal groove of short length in which the clamping knife 401 can slide longitudinally to some extent.

When the blade 300 is used to cut an article, the blade 300 itself tends to slide in and out in a telescopic manner.

When the blade 300 has a tendency of extending outwards, the two connecting rods 402 corresponding to the outer sides can be pushed outwards by the knife clamping piece 401, so that the two connecting rods have a tendency of expanding towards two sides, and the tendency can push the corresponding damping blocks 403 to partially protrude out of the respective windows 201a-1 and jointly press the inner side walls of the splicing bodies T to form a friction resistance; and the greater the tendency of the blade 300 to slip, the greater the friction. Preferably, the outer surface of the damping block 403 is coated with a resistance increasing layer for increasing friction force, and the resistance increasing layer may be a rubber layer.

When the blade 300 has a tendency of retracting inwards, the two connecting rods 402 corresponding to the inner sides can be pushed inwards by the knife clamping piece 401, so that the two connecting rods also have a tendency of expanding towards two sides, and the tendency can push the corresponding damping blocks 403 to partially protrude out of the respective windows 201a-1 and jointly press the inner side walls of the splicing bodies T to form friction resistance; and the greater the tendency of the blade 300 to slip, the greater the friction.

It should be noted that: only when external force directly acts on the blade 300 and causes the blade to have the tendency of stretching inward and outward, the telescopic fixing assembly 400 can be actuated to work to form extrusion friction. If the inward and outward extension and contraction of the blade 300 is controlled only by pushing the above-mentioned pushing block 204b, the telescopic fixing assembly 400 is not caused to operate because there is no tendency to push and pull the knife clamping member 401. Therefore, the above-mentioned principle of action can ensure that: when the blade 300 is used for cutting an article, the telescopic fixing assembly 400 can ensure that the article can stably work and does not move; when the blade needs to be manually controlled to stretch, the stroke matching between the locking block 202c and the sliding path 105 can ensure the smoothness of manual pushing and pulling, and the operation is not laborious.

Further, the insert holder 401 includes a slide ring 401a passing through the micro-motion groove 201b and a pressing bolt 401b capable of being screw-coupled with an inner sidewall of the slide ring 401 a. The slip ring 401a may be an annular structure, and its inner side wall has an internal thread, and the extrusion bolt 401b is connected with the internal thread fit of its inner side wall, realizes the mode of detachable connection. The sliding ring 401a is provided with a limiting seat which is positioned on one side of the sliding sheet 201, and the bolt head 401b-1 of the pressing bolt 401b is positioned on the other side of the sliding sheet 201, so that the sliding sheet 201 is positioned between the limiting seat and the bolt head 401 b-1. The blade 300 is provided with a connecting hole 301, the connecting hole 301 is sleeved on the periphery of the sliding ring 401a and clamped between the bolt head 401b-1 and the sliding sheet 201, and clamping and limiting of the blade 300 are achieved. The limiting seat can be a convex block structure and can be placed on one side of the micro groove 201 b.

Preferably, the sliding ring 401a is provided with a first connecting seat 401a-1, a second connecting seat 401a-2, a third connecting seat 401a-3 and a fourth connecting seat 401a-4 corresponding to each connecting rod 402.
